A SYSTEM FOR FASTENING A RAIL

Abstract This invention relates to a system for fastening a rail (10, 142, 222, 224, 252, 300, 302) having a rail foot (16, 236, 258) resting on a support (34, 170, 230, 310, 348), comprising a load-distributing plate (14, 144, 226, 228, 304), arranged between the rail foot and the support, a resilient first intermediate layer (30, 136, 176, 250, 312) supporting the load-distributing plate relative to the support, and, if required, a second intermediate layer (32, 196, 232), which extends between the first intermediate layer and the support and comprises an essentially non-resilient material, a holding element (26, 28, 106, 108, 236, 254, 322) connected to the support, from which holding element extends at least one elastic clip (22, 24, 234, 270, 272) having several legs (38, 40, 42, 44, 46, 48, 50) and which supports itself on the rail foot, characterized in that the holding element (26, 28 106, 108, 2336, 254, 322) is an insert, which is removably insertable into the load-distributing plate (14, 144, 226, 228, 304) and which allows movement relative to the load-distributing plate in the direction of the support (34, 170, 230, 310, 348), whereby the load-distributing plate is directly preloadable via the holding element relative to the support, or wherein the holding element is formed together with the load-distributing plate as a unit, the holding element forming a unit with the load-distributing plate having a through-opening (70, 118, 186, 246), in which is arranged a second insert (62, 102, 304, 188, 220, 248), which insert is movable relative to the holding element and allows an adjustment relative to the holding element, and through which passes a screw element (78, 164, 190, 288, 324), connecting the holding element and the support (34, 170, 230, 310, 348) and which can be screwed into the support, whereby the load-distributing plate can be indirectly preloaded relative to the support by the holding element.
Full Text FIELD OF INVENTION
The invention relates to an arrangement for mounting a rail having a rail foot on
a support, such as a concrete tie using a load-distributing plate, such as a ribbed
plate, arranged between the rail foot and the support, a resilient first
intermediate layer supporting the plate relative to the support, and, if required, a
second intermediate layer, extending between the first intermediate layer and
the support, of essentially inflexible material such as hard plastic, a holding
element being connected to the support, from which holding element extends at
least one resilient clip which comprises several legs, and which supports itself
directly or indirectly on the rail foot.
BACKGROUND OF INVENTION
A corresponding arrangement is found in EP-B-0 619 852. Here, the clip exhibits
approximately an M-shape in plan view and comprises two outer legs and two
inner legs, which are connected to each other by arch sections. The outer legs
are fixed in receptacles of a holding element, whereas the inner legs, or rather
the arch connecting them, rest on a rail foot. The holding element comprises two
spaced-apart shoulders with U-shaped channel-like openings that serve as
receptacles, into which the ends of the outer legs can be driven, so that the
inner legs hold down, with the necessary prestress, the rail which is to be
secured. The holding element can either be embedded in a concrete tie through
a stud or can be joined, e.g. by welding, to a ribbed plate.
A clip, which in plan view exhibits an E-shape, for fastening a rail is known from


AT-C-350 608. For the purpose of fixing the clip, a leg is driven into a channel of
an anchor element, which in turn is cast into a concrete tie.
A clip with W-shaped geometry is described in DE-C-30 18 091. Sections of the
clip are fixed in a channel-like depression of an angular-guide plate. Opposing
sections of the clip rest on a rail foot. The clip itself is connected to a concrete tie
through a through-bolt.
Rail fastening systems with clips known in the art have the disadvantage that not
enough space is available, in particular in the area of rail switches and rail
intersections where the rails are positioned in close proximity to each other, for
positioning and securing the clips. For this reason, these areas in principle
require customized designs for fastening the rails.
OBJECT OF INVENTION
The problem to be solved by the present invention is to further develop a rail
fastening arrangement of the above-mentioned type in such a way that
uncomplicated construction measures can be used to secure the rail or rails in
the region of a switch, in particular, whereby an resilient bearing of the rail
should be possible to a degree as is known according to the state of technology
and is required in the area of switches. In particular, the goal is to provide the
capability of carrying a rail with simple design measures in such a way that the
spring system, formed by the resilient clip and the resilient first intermediate
layer, exhibits a characteristic curve with a bend, so that good damping is
provided when passing, but that otherwise a quasi rigid unit results.

Independently of this, it should be ensured that the stresses on the clips do not
lead to a loss in fatigue strength.
SUMMARY OF INVENTION
According to the invention, this problem is solved mainly by the fact that the
holding element is formed as a first insert that is removably insertable into the
load-distributing plate and/or forms a unit with the plate, and that the load-
distributing plate can be directly or indirectly preloaded relative to the support
through the holding element.
Direct preloading through the holding element means that the holding element
establishes the prestressing of the load-distributing plate, i.e. the degree to
which.


the resilient first intermediate layer is compressed in the absence of an additional
load on the rail. The load-distributing plate is then adjustable relative to the
holding element in the direction of the support, so that the required prestressing
of the clip can be effected. A construction of this type is intended in particular for
firm rail bearings.
In contrast, indirect preloading means that the load-distributing plate and the
holding element form a unit-be that by means of a positive connection, or by an
integral formation-and that the preloading is established by a spacer element,
which preferably is insertable as a removable insert into the holding element,
which consequently is adjustable relative to the insert.
By employing measures of this type, the bearing of the rail on the support point
can be developed as firm or soft as is required, whereby a high resilience can be
achieved through an indirect preloading of the load-distributing plate through the
holding element, since a relative movement between the load-distributing plate
and the holding element will not take place and as a result the clip itself does not
have to follow large excursions of the spring system. This ensures the required
fatigue strength.
As a further development of the invention it is provide'd that the holding element
has a base section with a shaped projection extending along the bottom, and
that from the area of the base section facing away from the shaped projection,
i.e. its upper side, extends at least one receptacle, such as a shoulder or
channel, in which extends one leg of the clip or a section of a leg.

In a sectional view, the shaped projection preferably exhibits a circular or oval
geometry of its circumference, whereby the planar extent preferably is smaller
than the planar extent of the base section. In a structure of this type, the
holding element is inserted into the load-distributing plate from the side further
from the support. If the planar extent of the base section is smaller than that of
the shaped projection, the holding element will have to be inserted from the
bottom of the load-distributing plate.


Differing from sleeper mountings known in the art, the invention proposes a
holding element with a clip, in which the holding element is removably insertable
into a load-distributing plate, which in turn can be forrned as a ribbed plate or as
an elevated region in the vicinity of a heel of a switch tongue. The holding
element is then secured by a screw element passing through it, such as a
through-bolt, the load-distributing plate being, at the same time, fixed by the
holding element.
In particular, it is foreseen that the shaped projection of the holding element not
only engages by a positive connection into the load-distributing plate, but rather
also has a shape- and friction-locked connection with the latter, if prestressing of
the load-distributing plate is to be achieved directly through the holding element.
When securing the holding element and with it the load-distributing plate, a first
support surface of the holding element rests on a section of the load-distributing
plate forming a second support surface. In addition, the holding element should
have an axial opening, in which is located a second insert, which is movable
relative to the holding element and through which passes the screw element,
e.g. a through-bolt, which connects the holding element to the support and
which can be screwed directly or indirectly into the support. If the holding
element is then fixed and therefore the load-distributing plate is fixed as well,
the screw element, or a disk-shaped element that the screw element passes
through, rests with a frictional connection either on a third support surface of the
holding element, at the side facing away from the support, or on the second
insert, depending on whether the load-bearing plate is to be prestressed directly
or indirectly through the holding element.

For prestressing to be applied indirectly through the holding element, i.e. when
the second insert is tightened positively between the screw element and the
support, or an essentially rigid plate arranged thereon, a special embodiment of
the invention provides that at least two projections protrude peripherally from
the shaped projection, with the.

respective clearances of the projections to the support surface extending from
the holding element being equal to or slightly greater than the clearance
between the second support surface, extending from; the load-distributing plate
and the bottom surface of the load-dissipating plate, along which extends or
from which extends the resilient first intermediate layer. Thus, the peripherally
protruding projections can embrace the load-distributing plate, making it possible
to achieve the desired positive connection.
To achieve this technically, an independently inventive proposal provides that the
holding element be connected to the load-distributing plate in a bayonet-joint-
like manner. For this purpose, the through-opening which accepts the insert, of
the load distributing-plate has a geometry that is matched to the outer geometry
of the shaped projection. However, the cut-outs associated with the projections
extend in such a manner that the holding element must be inserted into the
load-distributing plate in a position that is offset relative to the position that is
oriented towards the rail foot, so that it can subsequently be rotated and be
oriented towards the rail to be secured.
If, as mentioned, the holding element is preferably removably connected to the
load-distributing plate, then it is of course also possible that the two are formed
as an integral unit. For example, the load-distributing plate and the holding
element can be formed as one piece, for example by casting.

To achieve the desired prestressing, the following constructional options, in
particular, are available. If the load-distributing plate is prestressed directly
through the holding element, then, with the screw element or the disk-shaped
element through which it passes supported by fictional engagement, the holding
element rests through a fourth support surface on the support, such as the
concrete tie or the second intermediate plate, which is made substantially
inflexible and for example consists of hard plastic. A clearance then exists,
between the first and the fourth support surfaces of the

holding element, which is smaller than the thickness of the resilient first
intermediate layer, when the screw element is loosened, and the clearance
between the second support surface and the undersurface of the load-
distributing plate. Consequently, when the screw element is tightened, and thus
the holding element and therefore the load-distributing plate are secured, the
resilient first intermediate layer is compressed to the required degree and the
desired prestressing is achieved.
For indirect prestressing, i.e. the screw element or the disk-shaped rests in a
frictionally engaged manner upon the second insert, the second insert has an
axial extent which, upon tightening of the screw element, results in a
displacement of the holding element with the load-distributing plate in the
direction of the support and consequently a compression of the resilient first
intermediate layer. The screw element, i.e. its head or the disc-shaped element,
then obviously rests upon a region of the holding element. Since in this case the
holding element and the load-distributing plate form a unit, the clip only has to
compensate for tilting forces introduced by the rail, so that no loss of fatigue
strength occurs.
A further proposal of the invention provides that two shoulders, each of which
accommodates one leg section of the clip, extend from the base section of the
holding element, the screw element, such as a through-bolt, extending between
the shoulders. Also extending between the shoulders is the leg or legs of the clip,
which rests or rest upon the rail foot or upon an element, and by which rails
running next to.each other can be secured.

An independently inventive proposal of the invention, it is provided that the base
section of the holding element is arranged between two rail feet, that two pairs
of shoulders extend from the base section, that one clip extends from each pair
of shoulders, and that between two pairs of shoulders there extends a plate
element which is adjustable relative to the base element and which rests upon
the rail feet, and upon which rests at least one leg of each clip.

Instead of two pairs of shoulders, two spaced-apart channel-like receptacles can
extend from the base section in order to be able to accept a leg of a clip
exhibiting an E-shape in plan view, as described in AT-C-350 608.
By the construction of the clips which are supported on a plate element mounted
on the rail feet, reliable holding down of rails that run immediately next to each
other, as is the case in the region of rail switches and rail intersections, is
possible in a simple manner.
The base section, which comprises the two pairs of shoulders or the two
channels, preferably exhibits a quadratic geometry, whereby from the base
section projects a quadratically shaped protrusion, having a cross-section of
rectangular geometry with rounded corners and engaging the load-dissipating
plate and having a positive connection with the latter.
The intermediate plate, or its support surfaces for the clips, should then have a
slope that corresponds to the slope of the rail foot that is usually to be secured.
The holding element or the first insert comprises metal, whereas the second
insert comprises plastic, in particular polyamide with a fibre glass content
between 50% and 70%, preferably approximately 60%.

DETAIL DESCRIPTION OF INVENTION
The Figures, which always use the same reference numbers for identical
elements, illustrate fastenings for a rail extending in a rail switch. To fasten the
rails, one employs resilient tensioning clamps,-also referred to as clips-and
holding elements accepting the clips, as they have been described on principle in
EP-B-0 619 852, in particular in its FIGS. 1-5. In this respect, reference is made
to the relevant disclosure. However, the invention is not limited to the
corresponding shape of the clips. Furthermore, the teaching of the invention is
also realizable with clips of different geometry and with clips of a type that are

accepted by holding elements, which for the purpose of securing clips have a
channel, for example, instead of shoulders, as is known from the fastening
system according to AT-C-350 608. In this respect, reference is particularly made
to the relevant disclosure therein.
Figure 1 shows, purely schematically, a layout of a simple rail switch towards the
right. In this, the rails are supported on concrete ties and are secured, again
purely

as an example, by so-called Pandrol® clips, as described in EP-B-0 619 852.
Figures 2-7 illustrate the standard fastening of a rail on the track, i.e. a stock rail 10
immediately before the tip of the switch. The stock rail ] 0 rests in the usual manner
upon an intermediate layer 12 (pad), which in turn is arranged on a load-distributing
plate 14, which hereinafter will be referred as the ribbed plate. The rail 10 as well as its
foot 16, i.e. the foot's side edges 18, 20, are secured by clips 22,24 resting upon them,
which extend from holding elements 26, 28.
The ribbed plate 14 is supported by a resilient intermediate layer 30, which in turn rests
on an essentially inflexible plate 32, made for example of hard plastic. In this
exemplary embodiment, the plate 32 in turn extends directly from a concrete tie 34.
Below the rail foot 16,- the resilient intermediate layer 30 can have, for example
according to WO-A-200227099, recessed areas 36, which under normal loading of the
rail 10 extend at a spacing from the intermediate plate 32. Under excessively high
loads, the recessed regions will come to rest on the intermediate plate 32, so that the
intermediate layer 30 will become stiffer.
The clips 22. 24 have in plan view an approximate M-shape and comprise the outer legs
38, 40, which merge through arch sections 42, 44 into the inner legs 46, 48, which in
turn are connected by an arch section 50.
When fastening the clips 22, 24, the outer legs 38, 40 are driven into the holding
elements 26. 28. in particular into so-called shoulders 52, 54, or rather into hollow
spaces surrounded by the shoulders. Owing to the shape of the legs 38, 40, 46, 48 and
the shape of the arch sections 42, 44, the arch section 50 subsequently rests with
prestress upon the rail foot 16 or rather the respective longitudinal edge 18, 20 and thus

holds down the stock rail 10. In this, the arch section 50 is surrounded by a sleeve 56
consisting of electrically insulating material.
The basic design of the clips 22, 24 was described on the basis of clip 22 alone, but
this applies analogously to clip 24. In the following, the design of the holding elements
26, 28 will also be described by using holding element 26 as an example.
The holding element 26 and the shoulders 52, 54, which accept the outer legs 38, 40 and
each of which has a laterally open U-shaped channel 58, 60 for accepting the legs 38,
40, originate in a plate-shaped base section 62, which in turn on its bottom has a shaped
projection 64, which preferably exhibits a cup-shaped geometry with a circumferential
wall 66 and a bottom wall 68. The bottom wall 68 is provided with a through-opening
70, to accept an insert 72, which can also be regarded as an adjusting cone. The insert
has a through-opening 74, through which passes a shaft 76 of a through-bolt for
securing the holding element 26 and thus the ribbed plate 14. For this purpose, the
base section 62 rests with a first support surface 80 upon a section of the ribbed plate
14 forming a second support surface 82. The ribbed plate 14 has a through-opening 84
to be able to positively accept the shaped projection 64. To fasten the holding element
26, 28 and thus the ribbed plate 14, the respective holding element 26, 28, i.e. the shaped
projection 64, is inserted into the corresponding opening 84 of the ribbed plate 14.
Subsequently, the insert 72 is inserted into the through-opening 70 of the holding
element 26. The through-bolt is then screwed into a nut 88, which is accommodated by
a sleeve 86 arranged in the concrete tie 34. The sleeve 86 is accommodated by a
widening 90, which extends from a socket 92, which is embedded in the concrete tie 34
and which surrounds the shaft 76 of the through-bolt 78 in its assembled state, as
illustrated in the sectional view of Figure 2.
The through-bolt 78, i.e. its head 94, is supported on a washer 96, which in turn rests on
the interior surface of the bottom of the shaped projection 64. When the


through-bolt 78 is tightened, the holding element 26, 28 is drawn onto the essentially
rigid plate 32 and rests in frictional engagement with the latter . During this, the washer
96 rests upon the edge region of the interior surface of the bottom wall 68 surrounding
the through-opening 70, which consequently is referred to as third support surface 98.
Simultaneously, the ribbed plate 14 is pulled along, which resiliently prestresses the
ribbed plate 14, since the distance between the first support surface 80 of the holding
element 26 and its fourth support surface 100 resting on the plate 32 is smaller than the
thickness of the ribbed plate 14 and the resilient intermediate layer 30 in the relaxed
state, i.e. with loosened through-bolt 78. Tightening the through-bolt 78 consequently
compresses the resilient intermediate layer 32, which allows the desired prestressing of
the ribbed plate 14 to be achieved.
Under load, the stock rail 10 is able to deflect to the necessary degree. The resilient
intermediate layer 30, together with the washer 96, thereby forms a spring system,
which allows realization of a characteristic curve with a knee-point, which is shown in
DE-C-42 43 990. Of course, an equivalent characteristic curve could also be achieved if
the head 94 rested directly on the bottom wall 68.
Since the prestressing of the ribbed plate 14 is provided by the holding element 26, 28, a
relative movement is possible between the ribbed plate 14 and the holding element 26,
28 and therefore the stock rail 10. As a result of this, the clip 22, 24 must if necessary
execute spring excursions, in dependence on the subsidence of the stock rail 10, which
can lead to loss of fatigue strength. To eliminate this possibility, the prestressing of the
ribbed plate 14 can be realized, in accordance with the exemplary embodiment of
Figures 5-7, by an insert 102, 104 passing through the holding element 26, 28. In this
case, one employs a holding element 106, 108, which is positively connected to the
ribbed plate in a bayonet-joint-like manner.
As illustrated particularly clearly in Figure 7, the holding element 106, 108 has a shaped
projection 110. which exhibits a circular cross-section with two peripherally protruding
projections 112, which in turn have a semi-circular cross-sectional geometry.


Irrespective of this, the shaped projection 110, corresponding to the shaped
projection 64 of holding element 26, 28, has a circumferential wall 114 as well as a
bottom wall 116 with an opening 118. Consequently, the circumferential wall 114
corresponds to a hollow cylinder. In contrast, the geometry of the circumferential
wall 66 of the shaped projection 64 of the holding element 26, 28 has an oval cross-
section, in order to secure, by interlocking insertion into the ribbed plate 14, a proper
alignment of the clips 22, 24 relative to the rail foot 18 or its side edges 18, 20.
The circumferential wall 114 of the shaped projection 110 is surrounded, in a form-
fitting manner, by inner surfaces 120, 122 of openings 124, 126 in the ribbed plate 14,
the peripherally protruding projections 112 extending along the bottom 128 of the ribbed
plate 14. Further, in accordance with the exemplary embodiment of Figures 2-4, the
holding element 106, 108 rests with its base section 130, i.e. with the lower surface of
the base section, forming the first support surface 80, upon the top of the ribbed plate
14. the clearance between the first support surface 80 and the peripherally protruding
projection 112 corresponding to the thickness of the ribbed plate 14 in the region of
the opening 124,126.
To allow insertion of the holding elements 106, 108 into the openings 124, 126, the
openings 124, 126 have cut-outs 132, 134 matching the projections 112, the projections
112 passing through these in a position of the holding element 106 in which the latter is
not aligned properly relative to the rail foot 16. When the holding element 106 has
been inserted into the opening and the peripheral projections 112 extend along the
bottom 128 of the ribbed plate 14, the holding element 106 is rotated to the proper
alignment relative to the rail foot, the holding element 106 being connected to the
ribbed plate 14 in a bayonet-] oint-like manner. Now, the insert 102 is inserted into the
opening 118 of the bottom wall 116. The insert 102 then exhibits a height such that
during tightening of the through-bolt 78, the required prestressing of the ribbed plate 14
can be achieved by compressing an intermediate layer 136 arranged below the ribbed
plate. 14. The resilient intermediate layer 136 is then attached -otherwise than the
exemplary embodiment of Figures 2-5 - at the bottom 128 of the ribbed plate 114. This
can be effected by vulcanizing.


Insertion of the holding element 106, 108 into the ribbed plate 14 and thus the
interlocking and friction-locking joining of these is also illustrated by Figures 20 and
21, so that extensive explanations arc not required. In Figures 20 and 21, the rail to be
secured extends above the holding elements 106, 108, which is shown in various
positions. Accordingly, the holding element 106, 108 initially is inserted into the
ribbed plate 14, a part of which is shown, offset by 90┬░ from its proper positioning and
is subsequently rotated through 90o. In this position, shown in the illustrations on the
right, the shoulders 52, 54 are oriented towards to the rail foot 16 or the side edge 18,
20 in such a manner that upon after driving the clip 22 or 24 into the space bordered by
the shoulders 52, 54, the clip 22, 24 rests via its arch section 50, or the sleeve 56
surrounding the latter, on the edge section 18 or 20, respectively, and therefore holds
down the rail 10 to the necessary degree.
Furthermore, the other reference numerals used in Figures 20, 21 correspond to those
used in other figures for the corresponding illustrated elements.
Prior to driving the clip 22, 24 into the holding element 104, 106, the latter and
therefore the ribbed plate are secured via the through-bolt 78, which is screwed into
the nut 88 and is tightened. During this, the washer 96 rests upon the insert 102 and,
when the through-bolt 78 has been tightened, the insert 102 rests upon the intermediate
plate 32, which consists of a hard material. Therefore, the insert 102 is friction-locked
between the intermediate plate 32 and the washer 96. Disks 138, 140 acting as disc
springs can be arranged between the bolt head 94 and the washer 96, as illustrated in
Figures 5-7. The disks 138, 140 act in a screw-locking manner. Alternative
constructions, such as for example NORD-LOCK washers, are also possible.
As described in connection with Figures 2 to 4, the resilient intermediate layer 136 and
the washer 96 form a compound spring system with a characteristic curve with a bend.

In the exemplary embodiment, the height of the insert 102, 104 is smaller than the
thickness of the bottom wall 116 of the holding element 106, 108 and the thickness of
the resilient intermediate layer 136 in the relaxed state.
Because the holding element 106, 108 is connected to the ribbed plate 14 by-
interlocking and friction-locking, these two are moved as a unit relative to the insert
102, 104, so that as a result no additional spring loads arise for the clips 22, 24 from a
subsidence of the stock rail 10. Consequently, fatigue strength is ensured.
The design of a removable holding element, which can be used to indirectly or directly
preload a load-distributing plate for a rail, in particular in the region of rail switches,
and further can be used to preferably removably arrange the load-distributing plate, is
not limited to application in the region of normal rails or in the region of a stock rail
immediately before a switch blade, but can also find use in the region of a tongue blade
142, which for reasons of simplicity was omitted in Figures 8 and 9, but is included in
the exploded view of Figure 10.
In this region of the rail switch, corresponding to the section B-B of Figure 1, the stock
rail 10 is arranged on a ribbed plate 144, from which removably extends a slide plate
146, on which the tongue blade 142 is slidingly adjustable.
The slide plate 146 can be removably fastened to the ribbed plate 44 via bar spring
elements 148. 150, which extend along the longitudinal side edges of the ribbed plate
144 and which can be loaded via thrust blocks 152, 154, which originate from the ribbed
plate 144 and have a U-shaped cross-section. The thrust blocks 152, 154 extend
between supports 156, 158, 160, 162 of the slide plate 146, upon which the bar spring
elements 148, 150 rest when the slide plate 146 is fixed.
In its end region on the slide plate side, the ribbed plate 144 is secured by a through-
bolt 164, which can be tightened by means of a nut 168, which is accommodated in a
positive connection by a collar 166, extending within a concrete tie 170, from which


extends the ribbed plate 144. Analogous to the explanations for the through-bolt 78,
the shank 172 of the through-bolt 164 is surrounded by sleeve 174, which is cast into
the concrete tie 170 and consists of an electrically insulating material.
As in the embodiments of Figures 2 to 7, the ribbed plate 144 is supported on a resilient
intermediate layer 176, which can be arranged as separate element below the ribbed
plate 144, or can be joined to the latter, which is preferably effected by vulcanizing.
For prestressing the ribbed plate 144, i.e. to compress the resilient intermediate layer
176 to the desired extent in order to provide the required degree of resilient support for
the support point formed by the ribbed plate 144 and the slide plate 146, a design is
chosen that is equivalent to that of Figures 5 to 7. Therefore, the ribbed plate 144 is
indirectly prestressed on the rail side by a holding element 108, which in principle
corresponds to that in Figures 5 to 7, so that the clip resting on the rail foot 16, or rather
on the side edge 20, or the left one in the illustration, is indicated by reference numeral
24.
Accordingly, the holding element 108 consists of a plate-like base section 178, which in
a plan view is rectangular, from which extends a shaped projection 180having a circular
cross-section, which consists of a circumferential wall 182 equivalent to a section of a
hollow cylinder as well as a bottom wall 184, which has a through-opening 186, into
which an insert 188 can be inserted with positive connection. The insert 188 accepts a
through-bolt 190, which can be screwed into a nut 192, which in turn is accepted in a
positive connection by a collar 194 in the concrete tie 170.
The insert 188 has a height, which, when the through-bolt 190 is tightened and there is
thus a friction-locked contact of the insert 188, on the one hand, on the plate 196, which
is arranged on the concrete tie 170 and consists of inflexible material such as hard
plastic, and on the other hand at the washer 198, through which extends the through-
bolt 190, ensures that the resilient intermediate layer 176 is compressed by the holding
element 108 and the ribbed plate 144 connected to the latter to a degree that is sufficient

to achieve the desired prestressing. Discs 202, 204 acting as disc springs can in that
case be arranged between the head 200 of the bolt 290 and the washer 198, in
accordance with the illustration of Figures 5 to 7.
The washer 198, which rests frictionally on the top of the insert 188, is also supported
on the inner surface of the bottom wall 184 of the holding element 108, which in turn
is connected by interlocking and friction-locking to the ribbed plate 144, as was
described in connection with Figures 5 to 7. In other words, projections 206 protrude
peripherally from the outer surface of the circumferential wall 182, which, given a
proper orientation of the holding element 108 relative to the rail foot 106, will extend
along the bottom surface of the ribbed plate 144.
To allow insertion of the holding element 108, the ribbed plate 144, which positively
accepts the holding element 108, i.e. its shaped projection 180, has a corresponding
through-opening 208 with an inner geometry that corresponds to the outer geometry of
the shaped projection 180, whereby the cut-outs 210, 212 corresponding to the
projections 206 extend in such a manner that the holding element 108 is to be inserted
into the ribbed plate 144 in a position in which the clip 24 would not be supported
properly, or would not at all be supported, on the rail foot 16, so that consequently the
holding element 108 must be rotated to reach its operating position. As a result of this,
the projections 206 extend below the ribbed plate 144 without a possibility of
detaching the holding element 108.
In other words, a design of this type realizes a bayonet-joint-like connection between the
holding element 108 and the ribbed plate 144.
For completeness sake, it must be pointed out, with regard to the embodiment of
Figures 8 to 10, that a further intermediate layer (pad) 214 can be located between the
foot 16 of the stock rail 10 and the ribbed plate 144, and likewise between the slide
plate 146 and the ribbed plate 144. The corresponding pad is indicated by reference


numeral 216.
The clip 24, in the exemplary embodiment, rests on the left side edge 20 of the stock
rail 10. The opposing side edge 18 is hold downed by the slide plate 146. In this
respect we refer to the customary designs.
The prestressing of the ribbed plate 144, i.e. the compression of the resilient
intermediate layer 176, is achieved in the end region of the ribbed plate 144, on the
slide plate side, via the through-bolt 164, which, via a washer 218, rests on an insert
220, having a height that is smaller than the thickness of the ribbed plate 144 and the
thickness of the resilient intermediate layer 176 in the relaxed state, i.e. when the
through-bolt 164 is loosened. Therefore, if the insert 220 is tightened between the
washer 218 and the plate 196, the resilient intermediate layer 176 is compressed
accordingly. Naturally, the height of the insert 220 is greater than the thickness of the
ribbed plate 144.
To ensure that the holding element 108 and likewise the holding element 106 of Figures
5 to 7 is not only properly oriented towards the rail foot 16 to hold down the latter, but
also will remain in that position, a lock pin 222, 224 is provided, which can be inserted
into a recess formed by sections of the ribbed plate 14, 144 and the corresponding
holding element 106, 108. The lock pin 222, 224 can only be inserted into the recess
formed in this manner if the component sections are properly aligned relative to each
other, i.e. form the opening for inserting the lock pin 222, 224, as schematically shown
in the drawings.
Figures 11 to 13 correspond to the section C-C in Figure 1 extending in the region of the
tongue heel. In this region, the tongue blade 142 is supported on and fixed to an
intermediate plate 228, which is arranged on a ribbed plate 226 and forms an elevated
area. For this, clips and holding elements are used which were described with reference
to Figures 5 to 10. so that on principle the same reference numerals are used for identical
elements. Consequently, the clip 24 securing the stock rail 10 extends from the holding

element 108, which as mentioned earlier is connected to the ribbed plate 226 in a
bayonet-joint-like manner.
In other words, the base section 178 extends along the top of the ribbed plate 226 and the
projections 206, given a properly inserted holding element 108, extend along the bottom
surface of the ribbed plate 226. This is how the desired positive connection is ensured
in bayonet-joint-like manner. The prestressing of the ribbed plate 226 is accomplished
via the friction-locked fit of the insert 188 between the plate 232, which is arranged on a
concrete tie 230 and consists of a hard material, and the washer 198, through which
passes the through-bolt 190, which can be tightened by means of the nut 192 secured in
the concrete tie 230.
When the clip 24 is properly aligned relative to the side edge 20 of the rail foot 16, the
holding clement 108 can also be locked by means of the lock pin 222.
The side edge 233 of the foot of the tongue blade, which faces away from the stock rail
also serves as support for a clip 234 of the previously-described design, which extends
from a holding element 236, which has a plate-like base section 238 that rests upon the
top 240 of the intermediate plate 228. The holding element 236 is then connected by
interlocking and friction-locking to the intermediate plate 228 and the ribbed plate
226, which supports the intermediate plate 228 and in the exemplary embodiment is
made in two pieces. This is realized in a manner described previously. For this
purpose, a shaped projection 242 extending from the base section 238 has protruding
projections 244. which in the usual manner can be inserted positively into the
intermediate plate 228 and the ribbed plate 226 and subsequently rotated relative thereto.
In this respect, reference is made to the description relating to Figures 5-10.
The through-opening 246 of the holding element 236 accommodates an insert 248, the
height of which provides the prestressing of the ribbed plate 226, i.e. the compression of
the resilient intermediate layer 250 extending from the bottom of the ribbed plate 226,
which can be vulcanized to the bottom of the ribbed plate 226 or can be embodied as
separate layer. The intermediate layer 250 can thereby have a fundamental design, as

shown for example in EP-A-0 953 681, i.e. can have recessed sections that only come
to rest on the plate 232 if, under excessively high loads acting upon the stock rail 10 or
the tongue blade 142, it is desired that the intermediate layer 250 become stiffer.
To hold down or load the stock rail 10 and the tongue blade 142 with appropriate above-
described clips at their mutually opposed side edges 18, 25, a design was chosen that
has independent inventive merit. Between the stock rail 10 and the tongue blade 142
extends a holding element 254, which has a plate-like base section 256, which is
rectangular in plan view, with a shaped projection 258 of rectangular cross-section
extending from the bottom of the base section. Analogous to the exemplary
embodiment described above, the cross-section of the shaped projection 258 is smaller
than that of the base section 256. The shaped projection 258 has a through-opening,
through which a through-bolt 288 can pass.
Viewed longitudinally of the rails 10, 142, two pairs of shoulders, 262, 264 and 266,
268 extend at some distance from each other, which in each, like the above-described
holding elements, form channel-like receptacles with U-shaped cross-sections for the
outer legs of clips 270, 272, which have a design and function corresponding to those
of e.g. clips 22, 24. Extending between the shoulders 262, 264 on one side and the
shoulders 266, 268 on the other side, there is an intermediate plate 274, which can be
viewed as a bridge element and which is adjustable relative to the holding element 254,
and rests by border sections 280, 282, bounded by steps 276, 278, upon the rail foot 16.
236 of the stock rail 10 and the tongue blade 142, respectively, or rather their side edges
18, 252, as is particularly well illustrated in the sectional view of Figure 11.
The centre legs of the clips 270, 272 then rest upon the top 286 of the intermediate plate
274, whereby the intermediate plate 276 is pressed onto the rail feet 16, 233.

Therefore, narrowly spaced rails, i.e. the stock rail 10 and the tongue blade 142 in the
exemplary embodiment, can be loaded in a space-saving manner via clips that are
employed in the other parts of the rail switch.
To ensure identical geometric conditions with respect to holding down, such as when the
clips are directly supported on a rail foot, the top surface of the intermediate plate 274
preferably has a roof-like geometry with slopes that correspond to those of the support
surfaces of the rail feet 16, 236 in those regions, which usually serve as support for the
clips.
Analogous to the holding elements 108, 236, the holding element 254 is fastened via
the through-bolt 288. Since the holding element 254 does not grip or have a positive
connection to the ribbed plate 256 - as was described on the basis of Figures 5 to 10 -,
but is only positively inserted into a matching through-opening 290, a relative
movement between it and the holding element 256, and thus additional loading on the
clips 270. 272, can occur in dependence on the subsidence of the ribbed plate 226.
However, since the holding element 254 is secured by the through-bolt 288 in the centre
region of the intermediate plate 274, which is considered a bridge element, the spring
excursions which occur can be kept low enough to not affect the fatigue strength of the
clips 270, 272. Also contributing to this is that the ribbed plate 262 is split in the
region of the through-opening 290, so that a relative movement occurs between the
section 292 accepting the stock rail 10 and the section 294 supporting the tongue blade
142. Correspondingly, the resilient intermediate layer 250 is also divided into sections
296, 298. The contact lines between the sections 292, 294 and 296, 298, respectively,
then pass through the through-opening 290.
A so-called double-securement, as was described in connection with the holding
element 254 and the directly adjacently extending stock rail 10 and tongue blade 142,
can also be found in the section D-D of Figure 1, the details of which arc shown in
Figures 14 to 16. Again, for elements that have already been described, in principle
the same reference numerals have been employed.

The rail sections 300, 302 merging into the tongue blade and the wing rail arc held
down on the outside by clips, which extend from holding elements and correspond to
those of Figures 5 to 7. Consequently, holding elements 106, 108 extend positively
from a ribbed plate 304, which is split in this exemplary embodiment. The clips 22, 24
can be driven into the holding elements 106, 108, after the holding elements 106, 108
have been properly aligned relative to the respective rail-foot side edges. In this
position, the holding elements 106, 108 are secured against rotation relative to the ribbed
plate 304 by lock pins 222, 224. The prestressing of the ribbed plate 304, or rather its
sections 306, 308, upon each of which rests one of the rail sections 300, 302, is
accomplished via the inserts 102, 104, which pass through the shaped projections 114
of the holding elements 106, 108 and have a positive connection to a concrete tie 310
via the through-bolts 78, i.e. are fixed between the washer 96, through which the
through-bolt passes, and the plate 32. Accordingly, arranged between the plate 32 and
the ribbed plate 304 there is an resilient intermediate layer 312, which, analogously to
the ribbed plate 304, is embodied in two pieces (sections 314, 316).
On the other hand, the mutually opposed side edges 318, 320 of the rail sections 300,
302 are held down by means of clips and an intermediate plate or bridge element, as has
been described in connection with Figures 11-13. In other words, between the rails
300, 302 extends a holding element 322, from which extend two pairs of shoulders 321,
323. 327 with unlabelled channel-like receptacles for outer legs of clips, which
correspond to the clips of the previously described type, i.e. the clips 270, 272, so that
the reference numerals relating thereto are used. The holding element 322, corresponds
in construction to the holding element 254, also has a plate-like or quadratic base
section 256 with a shaped projection 258, which has a through-opening, through which
passes a through-bolt 324 corresponding to the through-bolt 260 of Figure 13, to fasten
the holding element 322.
Across the holding element 322 extends an intermediate plate 326, which can also be
viewed as a bridge element and which performs the function of the intermediate plate
274 of Figures 11-13.


Therefore, the intermediate plate 326 is a separate component part, which is placed
upon the holding element 322, i.e. the top of the base section 256, whereby for the
purpose of achieving proper alignment relative to the holding element 322, the
intermediate plate 326 has, on its side facing the holding element, a recess 328 having a
width corresponding to that of the base section 256. In the case of proper positioning,
the intermediate plate 326 lies, at its side edges, which are bounded by steps 334, 336,
on the longitudinal side edges 338, 340 of the rail sections 300, 302, so that
subsequently the clips 270, 272 are driven into the holding element 322, i.e. into the
shoulders 321, 323, 325, 327.
The fact that the holding element 322 extends in the split region of the sections 306,
308 of the ribbed plate 304 allows a relative movement between the rail sections 300,
302 to take place, the spring loading of the clips 270, 272 being simultaneously
reduced.
A sectional view E-E of Figures 17 to 19 reflects the situation of the rail switch in the
region of the guide rails. A rail section 342, along which extend supports 344 for
accepting guide rail inserts 346, is fastened by holding elements and clips, which can
correspond to the construction of Figures 2 to 4, in particular Figures 5 to 7, i.e. a
position outside of a rail switch. In this respect, the same reference numerals are used
for identical elements, the construction of Figures 17 and 19, in which the prestressing
of the ribbed plate 14 is accomplished via the inserts 102, 104, being selected so that
consequently the holding elements 106, 108 have a positive connection to the ribbed
plate 14. so that no relative movement can take place between them.
The supports 344 are connected by through-bolts to the concrete tie 348 accommodating
the rail section 342. In this regard, reference is made to sufficiently well known
designs.

foot and the support, a resilient first intermediate layer (30, 136, 176, 250, 312)
supporting the load-distributing plate relative to the support, and, if required, a second
intermediate layer (32, 196, 232), which extends between the first intermediate layer
and the support and comprises an essentially non-resilient material, a holding element
(26, 28, 106, 108, 236, 254, 322) connected to the support, from which holding element
extends at least one elastic clip (22, 24, 234, 270, 272) having several legs (38, 40, 42,
44, 46, 48, 50) and which supports itself on the rail foot, characterized in that the
holding element (26, 28 106, 108, 2336, 254, 322) is an insert, which is removably
insertable into the load-distributing plate (14, 144, 226, 228, 304) and which allows
movement relative to the load-distributing plate in the direction of the support (34, 170,
230, 310, 348), whereby the load-distributing plate is directly preloadable via the
holding element relative to the support, or wherein the holding element is formed
