Description

The invention relates to a superstructure device for a switch with a block made of a steel high-strength grade existing tongue bed, wherein the block is connected to a lower part of a same or other than the high-strength steel existing material such as structural steel, in particular cohesively connected.

A corresponding superstructure device consisting of structural steel lower part is z. B. the DE-C-101 24 624 refer to. The lower part and the upper part are block-shaped and connected by screws, welding or pinning. In this case, the superstructure device extends over the length of the tongue bed. A corresponding construction is also found in the DE-C-101 12 979 , In the corresponding constructions integral components of the superstructure device are the tongue bed limiting the tongue bed and Beischiene.

Of the DE-U-298 24 701 is to be taken a superstructure device in which the Beischiene is a separate component and the stock rail and support bed for the tongue are integrally formed and form an elongated basic block. The basic block can have the geometry of an H, so that there is a cavity between the longitudinal legs of the basic block. A similar construction can be found in the DE-B-20 42 486 , In this case, heating rods are arranged in the heating chamber, which are pressed on the underside against the support bed by means of a pressure plate. The sheet extends at a distance from the bottom of the cavity.

From the DE-B-10 2004 048 751 For example, there is known a tongue device with a stock rail made of a wear-resistant tempered steel base block made by abrasive machining. The jaw rail bounded below a tongue plate supporting a sliding plate a cavity in which a heater is provided.

In the known superstructure devices, the block forming the tongue bed extends only over part of the total length of the tongue device, the ends usually being welded to control rails to form the overall tongue device.

From the DE-A-195 25 135 is an expansion joint for relatively longitudinally displaceable adjacent rail sections known as grooved rail sections.

In the WO 2004/065691 a switch is described, the tongue is stored in a box-like receptacle.

The present invention is based on the object, a superstructure device of the type mentioned in such a way that with structural simplification and material savings individual circumstances is taken into account. Also, the possibility should be created to easily integrate the superstructure device in a track.

According to another aspect, the possibility should be given to heat a tongue device in the region of the tongue bed to the required extent energetically favorable.

In order to achieve an aspect of the invention, it is proposed that the block extends beyond the length of the tongue bed and at least beyond one side of the tongue bed and that the lower part is an elevation of the block in the form of at least two mutually spaced supports. The lower part, which may also comprise a bottom plate to which the supports are connected as if welded, may be made of the same high-strength steel as the block, of another material which also includes a high-strength steel deviating from the material of the block, in particular mild steel consist.

In particular, it is provided that the block extends over the entire length of the tongue device on both sides beyond the tongue bed addition. Length of the tongue device corresponds to the standard.

However, there is also the possibility that the block extends beyond only at least one side of the tongue bed. In this case, it is provided in particular that the block extends at least as far as the entrance or beginning of the tongue device, whereas on the output side of the tongue device either the stock rail or the tongue rail or both the stock rail and the tongue rail can be provided with a transition rail profile or rail profile, the factory welded.

According to the invention, there is provided a superstructure device in which the tongue bed comprising the block and the stock rail defining this limit and adjacent portions of the tongue device are integrally made of high-strength steel, so that high wear resistance is provided. At the same time, however, the superstructure device can be made of material, since the lower part is not blocky, but consists of two mutually spaced especially consisting of structural steel supports that limit a gap in the desired extent easily heating is arranged such that they are operated energetically low can. However, the construction remains cost-effective, even if the lower part also consists of high-strength steel, since only material for the supports or for the supports and floor or base plate is required, from which the supports go out or connected to the supports as welded are.

However, deviations of a construction in which the block does not extend over both sides of the tongue bed over the entire length of the tongue device are also covered by the invention. This deviation may be necessary due to on-site or constructive conditions or requirements. On-site deviations can then lead to a change in the length if, for example, a fit into existing track gaps occurs. But also customer prescribed welding procedures, which are easier to use with conventional rails than with rails of high quality in a section of a rail to be welded, can be reason for a shortening.

Design deviations are deviations from control lengths that are used in interleaved tongue devices of complex track systems, e.g. Track harps, follow-up branches or multi-lane points systems cause shortening and / or lengthening of the overall lengths.

Extensions of the monoblock design are needed to avoid increasing the number of weld joints between the assemblies. Shorter extensions, until z. B. 400 mm, are integrated in the monobloc of the tongue device, longer extensions, from z. B. about 400 mm, will be conveniently welded factory rails. Plant-specific, the extension can be done before the end of the actual tongue device, so that consequently the usually the length of the tongue device having monoblock construction is shortened accordingly, the unit monoblock extension but the length of the tongue device projects beyond.

In other words, the block basically extends over the entire length of the tongue device, but can be extended or shortened to the extent necessary, the latter in particular to avoid on-site process-specific special expenses in the welding of the control rail with components made of high-strength steels and structural steel on site and cost-effective to take account of design features in track systems.

Thus, according to one embodiment, a superstructure device according to the invention can be provided in which the block extends beyond the length of the tongue bed, but not over the entire length of the tongue device. In this case, preferably, the block in the region where it does not coincide with the extension of the tongue device is welded to a control rail, which then forms a unit with the block. At least the block is then supported on the elevation according to the invention in the form of at least two mutually spaced supports.

Notwithstanding known tongue devices, the superstructure device is designed with respect to the tongue bed beyond this as a monoblock, wherein in particular the superstructure device extends to the entrance or beginning of the tongue device. It is also possible for at least the cheek-rail-side end section or the tongue-rail-side end section or both the cheek-rail-side and the tongue-rail-side end section of the tongue device to be sections of the monobloc.

If the block does not extend over the entire length of the tongue device, transitional or standard rail profiles are welded to the remaining sections so that simple connection to the connecting rails in the track is made possible. In particular, however, it is provided that the superstructure device according to the invention extends over the entire length of the tongue device and is designed as a monoblock, without requiring welding of rails within the tongue device. In this case, the block thus comprises inlet of the tongue device in the form of a stock rail and end portion of the tongue device, ie stock rail and tongue rail.

Is according to the teaching of the invention, the superstructure device formed over the entire length of the tongue device, it is z. B. provided for a R50 switch, that the tongue device basically has approximately a length of about 5350 mm, that is about the length that has the tongue device standard with an R50 turnout. However, site-specific extensions or shortenings for the purpose of eg better welding in the track system do not limit the teaching according to the invention. In that regard, the figures are to be relativized. The decisive factor, however, is that the block is longer than the tongue bed and extends substantially over the entire length of the tongue device. The lengths of the blocks for further points are given the following restrictions: R25: in about 4900 mm R30: in about 4600 mm R50: in about 5350 mm R100: in about 7200 mm R150: in about 8500 mm.

The block comprising the tongue bed and the stock rail and insert formed integrally therefrom, and the block defining the tongue bed and / or the end of the tongue device, should consist of a rolled sheet or forged body from which the superstructure device with its sections is laser cut, autogenous cutting, thermal cutting, plasma cutting or by milling is worked out.

The block in the original state can have a width of about 370 mm and a height of about 100 mm, in order to ensure optimum material utilization.

Preferably, the uprights forming supports should be materially bonded to the block with respective outer sides of a support flush with one of the outsides of the block.

Furthermore, the supports should start from a base or base plate and in particular be welded to this. It is provided in hervorzuhebender embodiment of the invention, that of the underside of the block, so the tongue rail supporting tongue rest, the inner sides of the elevations forming pillars and extending therebetween inner surface of the bottom or base plate by introducing an insulation limited interior at least opposite the floor or base plate is thermally insulated, that is independent of air-related insulation. This can be done by casting, foaming or introducing loose insulating material. It is also possible, along the floor or base plate and, if necessary. Spaced to arrange this an insulating board with high thermal insulation or low heat transfer coefficient.

For increased thermal insulation is further provided that the insulation introduced into the interior is covered at least on the block side of a heat shield, such as a stainless sheet metal such as stainless steel, which has a poor heat conduction. Thus, the space receiving the heating is insulated at least at the bottom so that an energetically favorable operation of the heating is possible.

In a further embodiment, there is the possibility that the space receiving the heating not only on the bottom side, but also with respect to the elevation, so the rectangular in cross-section supports is thermally insulated, also casting, foaming or introducing insulating material in loose form possible is. In this case, the insulation with respect to the interior is preferably also covered by a heat shield.

With respect to the extending below the tongue bed cavity and its thermal insulation is to be noted that the relevant teaching is independent of the inventive design of the tongue device itself. Rather, the relevant teaching can be used anywhere where below a sliding plate on which a tongue rail is supported, a heated cavity extends. Therefore, the invention also relates to a superstructure device with a box-shaped body bounding an interior space, which is bounded on the head side by a tongue blade of a switch supporting sliding plate and the bottom side of a base and bottom plate and in which a heater is arranged, and is characterized that the interior is thermally insulated by means of a separately introduced into the interior insulation at least with respect to the bottom or base plate, wherein between the insulation and the underside of the sliding plate, the heater is arranged as heating rod.

In hervorzuhebender development of the invention, it is provided that in the outer side of the stock rail and / or the guide rail a recess such as recess or step extends, that the recess extends to a height which extends above the top of the slide plate, and that in the recess Insulation such as insulating wool or insulation board is arranged.

By these measures, the stock rail or the guide rail is isolated from the outside in an area in which the sliding plate extends and the tongue rail is supported on this. Thus, insulation in the contact area, so that in cold seasons freezing is avoided.

Furthermore, it is provided that the insulation is covered on the outside, in particular watertight. For this purpose, the insulation can be closed or covered on the outside by a metal sheet or a support supporting the block or the tongue bed.

In a related construction, the stock rail in particular on the outside a step, so that there is a cavity between the vertical portion and the outer cover, which is filled by the insulation. The insulation may extend from the horizontally extending upper portion of the step to the base plate of the tongue device. However, there is also the possibility that the portion of the insulation extending between the stock rail and the outer cover merges with that which surrounds the heater.

According to a self-inventive teaching, it is provided that the support has block or tongue bed side spaced-apart, in particular a comb-like geometry forming projections over which the block or the tongue bed is supported. By these measures, the contact between the support and the block or the tongue bed is reduced, so that a lower heat transfer occurs. It is heat conduction between the bottom plate and the support and thus reduced to the ground.

Between the projections extending spaces may be filled with portions of the insulation, which forms a unit in particular with the existing insulation in the interior or goes into this.

In particular, it is provided that the insulation outside of the heating along underside of the sliding plate and / or outside of the stock rail extends into or almost into the area in which the tongue rail contacts the sliding side or the stock rail on the inside.

With regard to the insulation, in particular the outside insulation of the stock rail is to be noted that the relevant teaching is not necessarily related to block structures. Rather, the isolation thereof is also common in conventional tongue devices, e.g. possible in VDV design. In that regard, the teachings relating to insulation are to be considered detached from a specific type of tongue device.

Furthermore, a superstructure device with a made of a high-strength steel grade tongue bed, comprising stock rail, Beischiene and tongue rail a soft supporting sliding plate, the block with a lower part of a same or another high-strength steel existing material, such as mild steel, is connected , Is connected in particular cohesively, characterized in that the tongue bed to form a block of materially interconnected individual parts in the form of the stock rail, the sliding plate and the Beischiene, and that the lower part is an elevation of the block in the form of at least two mutually spaced supports ,

With this construction, the same advantages as in the monobloc construction according to the invention are achieved. In that regard, reference is made to the relevant explanations and explanatory features, which also apply to the alternative solution. For more details, advantages and features of the invention will become apparent not only from the claims, the features to be taken these features - alone and / or in combination, but also from the following description of the drawing to be taken preferred embodiments.

In the following description of a superstructure device according to the invention this is explained with reference to a grooved rail superstructure device, without thereby the teaching of the invention is to be limited.

Furthermore, the same reference numerals are used in principle for the same elements in order to simplify them.

In order to clarify the invention over the prior art and to delimit from it, is in Fig. 12 a tongue device illustrated in schematic representation with a nomenclature according to the VDV guidelines. Furthermore, in the Fig. 13 a schematic representation of a switch reproduced, which is composed of a tongue device 100, an intermediate rail portion 102 and a core portion 104. The tongue device comprises according to the Fig. 12 a total length V + 1z, where V is an extension over the length 1z at the start of the turn, which is to be considered when using an electric chamber heater.

An in Fig. 1 Tongue device according to the invention shown in plan view as the superstructure device 10 has a length 1z + V, resulting in the following values according to the control values for the tongue device according to the invention depending on the turnout radius, with conventional tolerances or site-specific extensions or shortenings for the purpose z. B. a better welding in a track system are to be considered: R25: 4900 mm R30: 4600 mm R50: 5350 mm R100: 7200 mm R150: 8500 mm.

In Fig. 1 should be symbolized by the blackened areas in the tongue device that extends over the entire length of the tongue device, a one-piece block 12, which consists of a steel high-strength grade with a strength up to 1600 N / mm ² or more, in particular a strength between 1200 N. / mm ² and 1600 N / mm ² or more. By way of example, mention may be made of the steels known by the names DILLIDUR, XAR or HARDOX or BAINIT.

From block 12 is z. B. by CNC milling, thermal cutting such as autogenous cutting, plasma cutting or laser cutting a tongue bed 14 worked out, which is bounded by a stock rail 16 and a Beischiene 18, which are thus integral parts of the block 12. On the tongue bed 14, a tongue rail 20 is then slidably disposed in the extent extent.

The tongue bed extends approximately the length between the cuts BB and DD and is bounded by a beginning 110 (entrance) with jaw rail section 112 and an end section 120 with curved control rail 122. The end section 120 and the beginning 110 may be sections of the block 12 ,

However, there is also the possibility that inlet and / or end portion area are not sections of the block 12, but consist of transition or rule rail profiles. As a result, complex welding of the control rail with components made of high-strength steels and structural steel are avoided on site. The connection of short-transition rail profiles in the inlet or end section area can be carried out at the workshop.

A block design belongs to the state of the art, but not in terms of their length; because according to the prior art, the block has a length corresponding to the tongue bed.

Deviating from prior art constructions is further provided according to the invention that the block 12 is not connected to a block-like base, but with parallelepiped or rectangular rectangular supports 22, 24 as square sections of structural steel and thus elevated to this, which in turn of a base plate or Bottom plate 26 go out. The supports 22, 24 are preferably connected to both the block 12 and the bottom plate 26 cohesively. Furthermore, it can be seen from the figures that the outer sides 28, 30 of the elevation, that is to say the supports 22, 24, are aligned in the outer sides 32, 34 of the block 12.

The supports 22, 24 and the bottom plate 26 may be referred to as the lower part or only the supports 22, 24 as the lower part.

The elevation consists of a material such as structural steel and is therefore inexpensive to produce.

As the Fig. 5 (Section DD) illustrates, the tongue rail 20 can be fixed by a brace in the direction of the bottom of the block 12 wedge 38 in the tongue root. A required for this purpose and the wedge member 38 passing through screw 40 is over a in a chamber 42 of a further cuboidal support 44, which represents a portion of the elevation for the block 12 in the region of the section DD, existing nut 41 engageable so as to the wedge member 38 in Direction of the bottom of the block 12 when fixing the tongue rail 20 to adjust or to solve the wedge 38 when replacing the rail 20.

Due to the teaching of the invention, it is possible to heat the tongue device to the desired extent energetically favorable. For this purpose, it is possible to introduce into the between the bottom plate 26, the supports 22, 24 and the bottom of the block 12 limited interior 46 according to the following explanation a heater such as a heating element 48, to the required extent relative to the supports 22, 24 and the bottom plate 26 is isolated by means of an insulating material - also simplifies insulation - so that as a result minimizes heat loss and a desired heating of the tongue rail 20 supporting tongue rest 15 takes place.

So is after the Fig. 6 an insulation 50 in the U-shaped section to isolate the heating rod 48 receiving gap 52 both to the supports 22, 24 and the bottom plate 26. The insulation 50 may consist of a foam material, of a molded material or of loose insulating material, which is covered with respect to the gap 52 via a heat shield 54, which has a poor heat conduction. This may be a stainless sheet so in particular stainless steel.

According to the embodiment of Fig. 7 is the heating element 48 receiving gap 52 with respect to the bottom plate 26 isolated, the insulation 56 may also be covered by a heat shield 54 and can be introduced by casting, foaming or in loose form.

According to the embodiment of Fig. 8 the inner space 46 is partially filled by an insulator 58, which has an L-shape in section, so that the space 52 is insulated from the base plate 26 and the right-hand support 24. Otherwise, the insulation 58 according to the explanations to the 6 and 7 trained and also be covered by a heat shield 54.

As insulation 60 according to Fig. 9 It is also possible to use an insulating panel 60 with high heat insulation or low heat transfer coefficients. In the embodiment, the insulation runs parallel and spaced from the bottom plate 26, wherein the heating rod 48 or other suitable heating receiving space 52 is also thermally insulated from the supports 22, 24, wherein an insulation according to the Fig. 6 to 9 may be provided, so insulating material in potted or foamed or loose form, the insulation 62, 64 may be covered over the gap 52 via a heat shield 54. This also applies to the insulation 60, so the insulation board 60 or other suitable insulation.

After Fig. 10 extends only parallel to the bottom plate 26, the insulation 60 in the form of an insulating board with this over the gap 52 covering heat shield 54th

The embodiment of Fig. 11 is similar to the Fig. 8 in that the intermediate space 52 is surrounded by a sectionally L-shaped insulation which is composed, on the one hand, of the insulation 60 and, on the other hand, of the insulation 64, which in turn are covered by a heat protection plate 54 in relation to the intermediate space 52.

In the Fig. 20 - 23 Further embodiments of tongue devices are shown with insulation to allow an energetically favorable heating and also to achieve an extent to an extent that freezing of the tongue rail in their contact surfaces to the stock rail and the slide plate is omitted or reduced. In the following description, the same reference numbers are used in principle for identical elements.

Of the Fig. 20 is a section through a tongue device of welded profiles and construction profiles similar to a tongue device in VDV type refer, which consists of a stock rail 116, or guide rail 118 and an extending therebetween sliding plate 114, on a support, the inside along the stock rail 116 extends, and the Beischiene 118 is supported.

The stock rail 116 and the guide rail 118 start from a base plate 126. On the slide plate 114, a tongue rail 120 is adjustable.

The guide rail 118, the slide plate 114 and the stock rail 116 define an interior 146, which can also be referred to as a chamber, in which a heater 148 extends below the slide plate 114. This is surrounded by an insulation 150, which is composed in the embodiment of a running below the heater 148 Sandwichisolierplatte 152 and the side of the heater 148 surrounding insulation preferably in the form of insulating wool. In that regard, with regard to the insulation, a construction or a course chosen, as for example the Fig. 9 can be seen.

Notwithstanding the embodiments of the 6 and 11 the tongue device in the area of the stock rail 116 is additionally insulated on the outside. For this purpose, the stock rail 116 in its outer side a Auskammerung 158, in which an insulation 160 is introduced, which is externally closed, for example with a metal plate 162 which is welded to the head of the stock rail and the foot. In this case, the Auskammerung 158 extends above the top 162 of the slide plate 114 to optionally in the contact area between the tongue rail 120 and the stock rail 116 to the contact surfaces of the tongue rail 120 to the stock rail 116 and the slide plate 114 to isolate in an extent that a freezing does not occur.

In Fig. 21 a tongue device is shown in block version, as this corresponds to the teaching of the invention, that consists of a the stock rail 116, the slide plate 114 and the case or guide rail 118 having block of high strength steel, which is supported on columns 122, 124 as the lower part, the in turn emanate from a base or bottom plate 126.

As the diagram illustrates self-explanatory, the stock rail 116 has in its outer side a step-shaped recess 164, which is spaced on the outside spaced from the support 122, so that there is a limited by the step space 166, which is filled with an insulation 168, which are up below the sliding plate 114 extends and surrounds the heater 148. On average, therefore, the insulation 168 has an L-geometry.

The in the Fig. 22 sectional tongue device is also formed block-wise with respect to the tongue bed, but deviating from the construction according to FIG Fig. 2 supported by supports 122, 126, one of which, namely the left support 122 is offset inwardly and - as the support 124 - from the bottom of the slide plate 114 emanates. The stock rail 116 also has a stepped recess 164 in its outside to provide a space into which insulation 172 is inserted. The space 172 is limited in the embodiment of an outside on the outside of the head of the stock rail 116 flush cover 170 such as sheet metal and the support 122, which is welded to the underside of the slide plate 114 mentioned. The inner space 146 between the inner support 126 and the support 126 extending in the region of the guide rail 118 has the heater 148 and an insulation 150 according to the embodiments explained above Fig. 20 on.

Of the Fig. 23 is to be noted a noteworthy invented construction of a tongue device, which has a block structure insofar as the stock rail 116, the guide rail 118 and the slide plate 114 are formed as a block of high-strength steel, which is elevated by supports 174, 176, of a reason - or bottom plate 126 go out.

According to the embodiments of the Fig. 21, 22nd the stock rail 116 has a stepped recess 164 on the outside, the support 174 being at a distance from the vertical portion of the stepped portion 164 so as to provide a space 166 into which the insulation 168 can be inserted, extending into the interior space 146 below the heater 148 extends.

Deviating from the construction of the Fig. 21 However, the block is not supported flat on the supports 174, 176, but virtually point-like, ie, the upper edge of the supports 174, 176 has a comb-like geometry, which is formed by spaced apart in cross-section, preferably rectangular projections which are connected to the block Thus, on the one hand with the underside of the stock rail 116, ie the horizontally extending portion of the step 164, and on the other hand with the underside of the slide plate 114 in the region of the support or guide rail 118 are in particular materially connected. The space between the projections is filled with insulating material, as shown in the sectional view Fig. 23 clarified.

The relevant construction is again based on the Fig. 24 - 28 be clarified. So is in Fig. 24 in side view a tongue device shown, the teaching of the invention with respect to the block design of the upper part and the supports of the lower part according to the Fig. 1-5 can correspond. In addition, in addition to the stock rail 12, the guide or Beischiene 18 and the tongue rail 14 purely in principle, an adjustment system 214 for adjusting the tongue rail 14 and a box 216 shown for a heater.

Like the detail X according to Fig. 26 is to illustrate, the upper part, so the tongue bed, which consists of high-strength steel and the stock rail 12, the Beischiene 18 and the slide plate 14 includes, not supported on the supports 22, 24, but over spaced mutually extending projections of the supports 22, 24, as related to the Fig. 23 has been explained. The relevant supports have been identified by the reference numeral 174, 176.

From the representation of Fig. 26 it can be seen that the projections are welded in sections with the block-like tongue bed in the areas marked "Section 2". This results from the filled rectangular welding sections 218. Between the projections, the supports 22, 24 and 174, 176 extend back to the tongue bed, so that there is a free space, which is filled with an insulating material 220. This is supposed to hatch in Fig. 26 symbolize.

The sectional views AA and BB according to Fig. 27, 28 then lead to constructions such as these Fig. 23 can be seen, the Fig. 28 of the Fig. 23 corresponds and the Fig. 27 a section through the tongue device reproduces, in which the tongue bed is supported on the supports 174, 176 and 22, 24 and integrally connected thereto.

Notwithstanding the illustrations in Fig. 23 is in Fig. 28 illustrates that the insulation, which extends into the space between the projections, is sealed on the outside with a material that prevents ingress of liquid. The corresponding areas are identified by the reference numeral 222.

The relevant construction for reducing heat conduction between the lower part and the upper part of the tongue device is also possible for conventional tongue device constructions, as shown in FIGS Fig. 29, 30th purely in principle is clarified. This is a section of a tongue device to remove, which consists of normal rails. The tongue device may thus be of the VDV type or similar type as shown in FIG Fig. 20 corresponds, so that corresponding reference numerals are used.

A comparison of Fig. 29, 30th illustrates that in the webs both the stock rail 116 and the Beischiene 118 through holes 224, 226 are provided as holes, which are filled by an insulating material 228, 230.

The Fig. 29, 30th should convey in principle that the reduction of the heat conduction by introducing insulation in the transition region between the lower and upper part of a tongue device detached from the special construction ownfinderischen content.

The above-described inventive features with regard to the insulation of the interior space 46 have their own inventive content and apply regardless of whether or not a monoblock construction according to the invention is used. Rather, the relevant teaching is everywhere applicable, where below a tongue rail supporting plate is a cavity in which a heater is arranged.

Of the Fig. 14 is an independent solution thought, which differs from the Monoblockweise previously described type in that the stock rail 210, Beischiene 212 and slide plate 214 are separately manufactured components, which are materially connected together to form a block. Thus, replace the jaw rail 210, the Beischiene 212 and the slide plate 214, the monobloc 12. The lower part of the tongue device corresponds to the above-explained teaching, so represents an elevation, which consists of the supports 22, 24, in particular of structural steel, which of the bottom or base plate 26 go out.

Based on 15 to 18 should again be explained the teaching of the invention. The Fig. 15 corresponds to the Fig. 1 , In this case, the superstructure device extends to the block 12 and the components according to Fig. 14 and the lower part over the entire length of the tongue device. According to Fig. 16 I extend the superstructure device from the tongue device input or beginning over the entire tongue bed and has a welded-on rule rail section at the end both in relation to the jaw rail and the tongue rail.

According to Fig. 17 the block is formed on the tongue rail side to the end of the tongue device. In contrast, the end portion of the stock rail is a control rail. The block itself extends from the entrance or beginning of the tongue device and extends over the entire tongue bed.

According to Fig. 18 the block is formed from the beginning or entrance of the tongue device to the end of the tongue device with respect to the stock rail. Outside the tongue bed on the other hand, the tongue rail is a rule rail.

Of the Fig. 19 Once again possible variants of the teaching of the invention can be seen. In the drawing, a section of a switch is shown in plan view, in which the length of a tongue device is designated by reference numeral 200 according to standard. The basic length of a monoblock construction with elevation according to the invention is provided with the reference numeral 202. Consequently, the lengths 200, 202 are the same.

If on-site or design deviations from the control length are required, the monobloc can be shortened by a required length K, for example. In the Fig. 19 For example, at the beginning and at the end of the monoblock, an abbreviation marked K is shown by way of example. Thus, in this embodiment, the actual location of the monoblock of the invention is: 202-2K.

On the shortened monoblock then rule rails can be welded, which can go beyond the length of the tongue device according to standard (reference numeral 200) according to the drawings. The corresponding extensions are marked V. Of course, it is also possible to connect a monoblock in control length 202 at the factory with standard rails, as the areas V illustrate.

Thus, the actual overall length 206 of the factory manufactured tongue device may be longer than the tongue device 200 according to standard.

The structure of the different embodiments with respect to the block construction and the lower part corresponds to that in connection with the Fig. 3 to 5 has been described, as well as the specification of the sections BB, CC and DD to express.
