Description

Plate element for guiding rail and manufacturing method thereof

The present invention relates to a plate member provided for guiding a rail at a rail fixing point, and which is constructed of a plastic material.

The invention is also related to a method for manufacturing a plate element of this type.

Modern rail fastening points, particularly used in heavy duty trucks or in areas of high speed rail lines, often contain different sheet-like components made of plastic material that are used to support and guide the rails that are awaiting fixation.

These plate-like components for fixing rails include those known in the technical language as "manipulation plates", "liners", "angular guide plates", "spacer plates", "pressure distribution plates" and "ribs". Plate" plate.

In practice, this type of control panel has a dual function as part of a system for securing railroad tracks for railway vehicles. In one aspect, it is used to laterally guide the rail and absorb lateral forces thereon when the system is fully assembled in the track, the transverse force being tied to the respective rails in the respective fixtures Appears when the pressure is over. On the other hand, a spring element is generally supported and guided on the manipulating plates, and the spring element applies the required elasticity to press the rail against the respective subsoil. Holding power.

In order to accomplish this dual function, the known steering panel generally has a contact surface that acts against the foot of the rail to be fixed in a fully assembled position against the rail vehicle as it passes over the rails These orbits work. The manipulating plates are formed by a shoulder portion of the manipulating plate opposite to the contact surface and pivoted away from the rails and acting against a shoulder formed on the respective subsoil The support surface, or at least one of the fastening elements that securely couple the control panel to the respective subsoil, is supported against the respective subsoil of the rails.

If the control panel is constructed as an "angular guide plate", an additional recess may be formed on the underside of the control panel extending in the longitudinal direction of one of the control panels, the recess being assembled when assembled Positioned in an interlocking manner in a correspondingly formed concave portion of the subsoil. In this manner, the position of the manipulating plate is laterally fixed to the longitudinally extending portion of the tracks.

In order to simultaneously tension the springs arranged on the control panel against the subsoil, a passage opening leading from the upper side to the lower side is regularly produced in the conventional control panel. The tensile element required to tension the respective spring element is inserted through the passage opening for coupling it to the subsoil supporting the rails. In this connection, generally, a screw or a threaded bolt is used as a tensile element that can be screwed into a screw anchor inserted into the subsoil.

In order to be able to transport, store and assemble it simply, in addition to the sufficiently high elasticity of the above-mentioned dual function of the control panel, in principle A low weight is required. This need can be met by the construction of such a control panel from a resilient, durable plastic material. An example of this type of control panel is described in DE 102 54 679 B4, DE 41 01 198 C1 and DE 20 2004 020 816 U1.

Liners, spacer plates, pressure distribution plates and ribs are used in the discussion of rail-fixing systems of this type in order to transfer loads which occur when the fixed point formed by one of the fixed systems of this type is pressed A wide area is covered and uniformly covers the direction of gravity of the subsoil on which the fixed point is constructed. With regard to such partial conditions in the respective rail fixing system and their assembly positions, for this purpose it extends at least to cover the width of the foot of the rails measured transversely to the longitudinal extension of the rails. Or extend laterally beyond this width. The panels in question are thus either placed directly on the respective subsoil in the discussion or supported by a layer or layers in the subsoil. It also constitutes a package of a plurality of layers composed of different plates and an intermediate layer composed of an elastic material, on the one hand, by means of an evenly distributed load occurring on the one hand, and on the other hand, waiting for the elasticity required for the long service life of the fixed rail, ensuring The required force resilience at a fixed point in the direction of gravity.

For such plate-like components for rail equipment, the ribs are a special example. When the two ribs which are parallel to each other and extend in a longitudinal direction are attached to the freely-prepared side of the rail which is abutting, the rib between them defines the rail to be fixed when assembled, and stands on its rail The contact area on it. The ribs are spaced apart from each other such that they laterally guide the rail and withstand when the fixed point formed by the respective rail fixing system is pressed The lateral force that appears.

In practice, the plate elements of this type of plastic material are generally made by injection molding in this discussion. Although plastic material plate elements are used in practice, the basic problem is, for example, the use of relatively large parts having large wall thicknesses and material volumes in the control panels, linings or ribs. This large shape can absorb the large forces generated during actual operation and provide sufficient area to support the rails of the rail fastening system or other components such as, for example, each spring element, according to current understanding of the board components.

Due to its high thick wall and material volume, it takes a relatively long processing time to manufacture well-known board components. Furthermore, it also has a negative impact on rigidity due to mixing and cooling problems. Therefore, in addition to the long processing time, an expensive procedure is required in order to ensure an optimum stiffness distribution covering one of the entire plate element volumes and in particular to avoid any loss of stability in the area of the weld formed by injection molding. .

However, the volume of material required can be minimized by a shape that is optimally compliant with the load that actually occurs. However, one of the best shapes of this type often leads to a complex design that also bears a high demand for injection molding in industrial manufacturing.

In contrast to the background of the prior art mentioned above, the object of the invention is to produce a panel element which can be produced in a particularly simple and cost-effective manner and which has the best properties. A method of making this type of plate element is also provided.

In terms of the board component, the design according to the present invention is as in the patent application This is done for the board component of item 1.

In the case of this method, the solution to the above object of the present invention is to complete the panel element of the present invention by the measure of item 15 of the patent application.

Specific embodiments and variations that are advantageous in the present invention are set forth in the appended claims, and are explained in more detail below in conjunction with the general inventive concept.

A plate element of the invention for securing a rail in a rail fixing point is thus formed in at least two parts which are formed in a space spaced apart from one another and which are connected to one another in a solid manner.

The method of the invention for producing a plate element of this type comprises the steps of: - producing the portions of the plate member that are separated from each other in space by means of a tool and - bonding the portions to the plate member.

Thus, a plate element for rail fixing is produced, the plate element being constructed of at least two parts that are rigidly interconnected, the at least two parts being initially prefabricated and then joined together in another working step so that they are tied Permanently and firmly connected.

The plate element of the present invention is characterized in that two or more of the components are not bonded during manufacture of the plate member in the tool for this purpose, for example, in a finished processing step that is feasible in injection molding manufacturing. It is the portions of the board element that are combined in an individual step that is outside the scope of the tool.

The division between the individual parts of a plate element of the invention may be selected such that the individual components are assigned to perform the function in an optimal manner, individually and in the state in which they are combined in the plate element. . In addition, it is expedient for the dividing plane formed between the two parts to be parallel at least in sections and at a distance from one of the contact surfaces of the plate element, with the plate element being located at the contact surface Stand on the subsoil when using the position. Thus, for example, it is useful when a half of the lower plate that is placed on the subsoil and is resistant to wear is combined with a second half of the plate on which the composite is made of a plastically pliable material. And thus it is desirable, but less resistant to wear, to form the desired molded portion on the sides above the plate members.

Alternatively, the division between individual portions of a plate member of the present invention can also extend from the lower side of the plate member to the upper side. In this way, for example, a control panel for one of the sections of the section for the lateral guiding position to be in direct contact with the lateral edge of the foot of the rail to be guided can be constructed of a highly wear-resistant material, The segment of the steering panel, which is independently made from the first segment, can be constructed of a lighter and more malleable material that can achieve lighter weight and complex shapes, regardless of the material in the second segment. Low rigidity ensures a high enough inherent stability.

A particular advantage of the present invention is that one of the panel elements of the present invention is divided into at least two portions to reduce cycle time in manufacturing. This applies in particular when the parts of the plate element are made of a plastic material, since the manufacturing time required for the injection molding of the plastic material part is secondary to the wall thickness of the part in question. In this way, in a two-shot injection molding tool In a processing cycle that is part of one of the methods of the present invention, the two portions are capable of simultaneously producing a substantial reduction in the idle time required to fill the mold and cure.

The individual parts of a plate element of the invention can thus be fabricated together in a tool or in a different tool prior to assembly. It is therefore desirable to manufacture simultaneously in a tool if the parts are made using a forming process that is the same or at least similar in processability. In this case, for example, if the portions of a plate member of the present invention are made of a plastic material, reinforcing fibers are disposed as necessary to ensure the indispensable rigidity. In this case, among the tools used, for example, a plurality of chambers corresponding to the number of the portions are formed, and the individual portions are separately and separately formed from the other portions.

Of course, these parts of a plate element of the invention can also be constructed with different tools. The material used in this part of the manufacturing discussion can be adapted to the load imposed on the parts during actual application. It can be understood that, for example, a part of the plate member which is practically loaded with a high-strength plastic material and the wire-molded component is formed on the other part, for example, can be less Made of a hard, fully shaped plastic material. It is also understood that the portion of a plate member of the present invention that is located on the respective subsoil in the mounting position and in some cases subjected to an abrasive load is constructed to be more complex and optionally complex. The other part of the molded component is made of a highly wear-resistant plastic material for the purpose of guiding a spring element or for guiding the liquid which has accumulated on the control panel.

Significant time and cost savings are achieved by the design of the present invention and thus the enabling process also has a corresponding effect in providing plate elements that are typically used for the first portion and the at least one other portion of a different material.

Since the portions constituting the plate member of the present invention are separately manufactured, different materials can be further combined with each other. It is thus intended that the load is expected to be particularly high, one part can be made of a metallic material such as cast aluminum or cast iron, and the other part can be composed of a plastic material.

The plastic materials that typically make the panel elements of the present invention are typically thermoplastic materials. Such plastic materials include, for example, polyamine (PA), polypropylene (PP), polyethylene terephthalate (PET) or general products of polymerization or polycondensation.

The portions of a plate member of the present invention can be firmly intertwined with each other via a force-fit, a positive engagement or an adhesive, or by a combination or a mixture of the types of connections. connection.

The portions of one of the panel elements of the present invention can also be selected depending on the load that is present in practice or the technique used to combine the preformed portions of one of the panel elements of the present invention for bonding or joining. Combine this way. It is therefore appropriate if a recess is shaped into a portion of the other portion that is placed therein. The portion that is configured to be recessed so as to be disposed therein is completely surrounded by the material of the other portion to an outer surface.

One of the types of arrangements, for example, when the system is placed in another part The portion of the recess is composed of a plastic material having high wear resistance and the other portion is resistant to environmental factors such as ultraviolet rays, moisture and temperature but has a relatively low wear resistance. It is useful to have a material composition. In this example, the outer portion protects the other portion of the recess disposed therein from the environmental factor and the outer surface of the portion disposed in the recess constitutes the layer, the layer having the respective rail fixed The associated plate element disposed on the subsoil on which the point is constructed.

The portions constituting one of the plate members of the present invention may also be constructed such that they interlock with each other in stages. For this purpose, one of the other portions is formed on the portion to protrude at least one concave portion that is interlocked into. The projection of the portion can constitute a recess that is locked to the recessed portion of the other portion. For this purpose, the concave portion can constitute a recess that is locked as a recess with the projection of the other portion. The projection of the portion can also be slightly larger than the concave portion of the other portion such that the projection can be pressed into the concave portion by applying sufficient pressure and thus forcedly locked thereto.

Another possibility is to create a strong connection between the components of a plate element by adhesive bonding. For this purpose, the parts can be bonded, welded (for example by ultrasonic welding, friction welding or welding of heating elements) or welded together. To achieve this, for example, a layer can be placed on the portion that causes an adhesive connection to one of the other portions, either automatically or in the presence of heat, radiant energy such as ultraviolet light, chemical energy or force. Under contact with the other part. a layer of this type, for example, by inserting a film into the part of the tool and by the phase The material of the relevant portion of the closed portion that is activated after the molding is formed by injection molding.

Of course, it is also possible to use special connecting members such as screws, nails, rivets, brackets and the like to hold the portions of the panel element of the present invention together. It is also understandable to use conventional bonding and joining techniques such as clinching or clipping. The use of a dissolvable member has the advantage that if a particular portion needs to be replaced due to wear or the entire panel member needs to be removed in an environmentally friendly manner, the portions can be easily separated from one another.

The correct positioning of the portions of a panel element of the present invention during assembly can be maintained by articulating the portions together in a hinge. The portions are thus pivotable on each other relative to the shaft formed by the hinge. For this purpose, the hinge can be constructed as a film hinge produced when the parts are made. For this purpose, the parts constituting one of the plate elements of the present invention can be produced separately from each other by plastic material in the same tool, each part having a chamber, wherein the chambers are hinged by the two parts The film hinges interconnected in a manner are connected to each other by a sufficiently narrow passage molded therein. It will also be appreciated that during simultaneous injection molding of the portions of a plate member, the sprue provided to fill the molding chamber can be designed such that after the portions are demolded, they form a portion that is relatively Joints that are folded together.

Moreover, the correct positioning of the portions can also be maintained by positioning the guides such as dies, pins or the like that are configured to properly position the portion on another portion.

It is particularly advantageous in the present invention that the panel element of the present invention is provided with a steering panel to direct the rails to be laterally supported in a rail attachment point, respectively. The advantages of the design of a plate element of this type of the invention are particularly suitable for securing the rail due to its relatively large volume and the high local load that this type of control panel must withstand. In this way, the multiple parts provided in accordance with the present invention, particularly in the type of control panel of this type, enable the mechanical and other characteristics of the individual segments of the control panel to be compliant in the practice.

Liners and ribs can also be produced in a cost-effective manner according to the invention, and the linings or ribs can likewise be of large volume and can be moulded in combination in order to minimize their weight and achieve any necessary Support and guiding functions.

Accordingly, the present invention provides a board component that can be used to secure a rail for rail vehicles in a particularly cost effective manner. In particular, if the parts of the plate element are made of a plastic material, this application makes it possible to considerably reduce the cycle time. The positive effect made of a plastic material is to achieve improved manufacturing quality via a reduced volume relative to the individual portions of the volume of an entire panel element, the manufacturing quality being characterized by minimized delay while minimizing Contraction. Furthermore, the present invention enables a substantial portion of a standardized, pre-manufactured and thus cost-effective, to be combined with a portion of the related requirements individually, thereby enabling a substantial cost to be achieved. save. For example, if the panel element of the present invention is a control panel, then the same lower portion can be optimally adapted to the respective supported position in the operation. An upper portion of the spring element of the type on the vertical plate is joined.

The plate elements 1, 2, 3, 4, 5, which are shown in the figures in the form of a control panel, are separately pre-formed separately from each other and then with the respective plates. The two components 1a, 1b; 2a, 2b; 3a, 3b; 4a, 4b; 5a, 5b are combined.

The control panels 1-5 are part of a fixed system for securing the rails S for use in railway vehicles. These individual components of one of the types of fastening systems are well known and have been described, for example, in the above publication. For example, this type of fastening system is provided by the applicant as "W14", "W21", "300" and "304".

In the case of this type of fastening system, a fixed point is formed, for example, on a sleeper or panel made of concrete, which constitutes the subsoil U which is only partially shown in Fig. 1. For its part, the subsoil U belongs to a fixed point formed by the use of a control panel 1-5 of the present invention.

The fixing system thus comprises a spring element which is generally in the shape of a ω and is designed based on a conventional tensile clamp, and is constructed as a screw or a threaded bolt for stretching the tensile element of the spring element against the respective subsoil And one of the manipulation panels 1-5. Of course, additional components also belong to the system, such as linings, elastic sheets, etc., in order to achieve a particular elasticity of the respective fixed points and an optimum pressure distribution.

For the sake of clarity, only those panels 1-5 are shown in the components generally belonging to a rail fastening system and partially indicate the subsoil U.

The manipulating panels 1-5 are each designed according to the well-known "angular guide plate" and have a square shape when viewed from above. On one of the longitudinal sides, a contact surface 1c, 2c, 3c, 4c, 5c is formed which extends respectively to cover the length L of the length of the control panels 1-5, which are utilized when fully assembled The respective operating panels 1-5 act against the bottom of a rail S that is fixed in the respective fixed points.

On the opposite longitudinal sides of each of the operating panels 1-5, a support surface 1d, 2d, 3d, 4d, 5d extending from the length L of the respective operating panel 1-5 is also extended. The support panel 1-5 is supported against the shoulder portion 7 by the support surface when assembled, and the shoulder portion is molded to the subsoil U carrying the steering panel 1. The subsoil U, which is only partially shown here, can be formed, for example, by a concrete sleeper, a concrete slab or an additional fixing component.

On the bottom side of the manipulating plates 1-5 combined with the subsoil U, a flat contact surface 1e, 2e, 3e, 4e, 5e is formed, which is used when fully assembled The contact surface is placed on the contact surface 8 of the subsoil U which is also flat.

In the region where the transition between the contact surfaces 1e, 2e, 3e, 4e, 5e and the lateral support surfaces 1d, 2d, 3d, 4d, 5d is made, an extension is also formed in a downward direction to cover each of the manipulation panels 1 A recess of the length L of -5, 1f, 2f, 3f, 4f, 5f, which is placed in a correspondingly formed groove 9 in the subsoil U. In this way, the position of the operating panel 1 in a lateral direction Q to the rail S is fixed to the subsoil U in an interlocking manner.

The passage openings 1g, 2g, 3g, 4g, 5g from the upper side of the operating panels 1-5 to a central position to the lower side are also formed in each of the operating panels 1-5 In one case, the tensile element, not shown here, is used for stretching a spring element supported on the upper side of the control panel 1 through the passageway and is not shown here to be assembled in the fastening system. Time guide.

Forming molding elements on the upper side of the manipulation panels 1-5, It is provided for guiding the central ring of the spring element and for guiding water and other liquids that may collect on the steering panel 1.

As mentioned above, the manipulation panels 1-5 are respectively constituted by a first portion 1a, 2a, 3a, 4a, 5a and a second portion 1b, 2b, 3b, 4b, 5b. The two parts 1a-5a; 1b-5b are separately pre-formed in a spatially separated chamber of an injection molding tool not shown here, respectively, with fiber-reinforced plastic material, and then with the respective control panel 1 -5 combination.

The plastic material of the upper portion 1a-5a of the respective manipulation panel 1-5 is set in each example to face the top portion in the assembly position (Fig. 1) so that the mold member is molded in the respective manipulation On the upper side of the plates 1-5, they are provided to guide the spring elements that are located there in each of the examples, or to guide the liquid with high precision. In contrast, when the assembly (Fig. 1) is placed on the subsoil U, the plastic materials of the lower portions 1b-5b of the manipulation panels 1-5 are adjusted so that the manipulation panels 1 - The lower portion 1b-5b of 5 provides a high degree of abrasion resistance.

In the steering panel 1 shown in FIG. 1, the dividing plane 1i extends in parallel with the contact plane 1e and the supporting surface 1d connected to the contact surface 1e between the two portions 1a, 1b in each example, And extending to cover the entire width B and length L of the operating panel 1. The two portions 1a, 1b of the operating panel 1 are joined together by an adhesive film that has been applied to the upper surface of the lower portion 1b of the operating panel 1, and when assembled (Fig. 1) the lower portion is placed in the The subsoil U is bonded to the upper portion of the manipulating plate 1 which is disposed in the upper region when assembled. The adhesive effect of the adhesive film can be activated, for example, by adding heat or radiant energy.

In the control panel 2 shown in Fig. 2, a receiving member 2j is formed into the upper portion 2a, wherein the second portion 2b is disposed in an interlocking manner. In this way, the second portion 2b is laterally surrounded by the material of the first portion 2a and positioned on the upper side thereof, while the lower side thereof combined with the subsoil U constitutes the contact surface 2e, which The control panel 2 is positioned on the subsoil U by means of the contact surface. In order to ensure that the second portion 2b is permanently clamped in the receiving member 2j of the first portion 2a, the second portion 2b can be pressed into the receiving member 2j. In addition to achieving a positive locking connection in this way, bonding can also be accomplished.

In the control panel 3 shown in Fig. 3, in an inverted design of the operating panel 2, a receiving member 3j is formed into the lower portion 3b, wherein the upper portion 3a of the operating panel 3 is disposed on the receiving member . In this example, the highly wear-resistant material of the lower portion 3b is surrounded by the less elastic but sufficiently molded upper portion 3a of the plastic material on its side surface and the lower side thereof so that only The upper side of the upper portion 3a constituting the molded portions required to guide each spring member is left unused. Here, at the same time, the upper portion 3a can be bonded to the receiving member 3j of the lower portion 3b.

In the manipulating plate 4 shown in FIG. 4, during the manufacture of the portions 4a, 4b, the chambers of the injection molding tools are joined together by a channel having a minimum height so that after demolding The portions 4a, 4b of the operating panel 4 are connected together via a thin strip. This strip constitutes a film hinge 4h extending around the length L of the manipulating plate 4 around the folded portions 4a, 4b for bonding to the manipulating plate 4. In this way, the film hinge 4h enables the parts 4a to be correctly positioned in a simple manner, 4b. In turn, the dividing plane 4i of the portions 4a, 4b extending over the width B and the length L of the operating panel 4 extends substantially parallel to the contact surface 4e of the operating panel 4, wherein it is recessed The area of 4d moves downward in the area.

This connection between the portions 4a, 4b in the control panel 4 shown in Figures 5 and 6 is ensured by forced engagement and press fit locking.

For this purpose, concave portions 4k, 4l, 4m, 4n in the form of slits are formed in the upper portion 4a, each concave portion extending from the upper side to the lower side of the upper portion and in the manipulation The longitudinal extension of the plate 4 extends. Here, a pair of concave portions 4k, 4l are disposed in the segment of the upper portion 4a disposed on the one side adjacent to the passage opening 4g, and are disposed at a distance from each other, and the other phase The corresponding recessed portions 4m, 4n are configured to enter the segment of the upper portion 4a disposed on the other side. The concave portions 4k-4n respectively have sharp edge recesses 4o projecting into each of the concave portions 4k-4n, which in each example are along the concave portions 4k facing away from the adjacent concave portions 4k-4n. This edge of 4n extends. On the lower side of the lower portion 4b, a protruding portion 4p is formed on the upper portion 4a in the region of the concave portions 4k-4n, the side of the protruding portion being tapered Formed by means.

In the region of the lower portion 4b of the operation panel 4 combined with the concave portions 4k-4n, a hollow portion 4q corresponding to the shape of the projection portion 4p is formed, wherein the operation panel 4 The protruding portion 4p is placed to interlock with the hollow portion when fully assembled. The protruding portion 4p and the hollow portion 4q constitute a one in this way by correctly positioning the portions 4a, 4b Attached to the supported positioning guide.

In the hollow portion 4q of the lower portion 4b, the notch projecting portions 4r, 4s are formed on the lower portion 4b, and in each of the examples, when the manipulating plate 4 is completely assembled, the notch projecting portion is locked with The concave portions 4k-4n are combined. With respect to the recess thereof, the recess 4o of the individual recessed portions 4k-4n is locked in an interlocking manner, in which manner the lower portion 4b is firmly held in the upper portion in an undetachable manner. 4a.

In the control panel 5 shown in Figures 7 and 8, a circular recessed portion 5k, 5l is formed in the design of a passage opening in each of the upper portions 5a, which is disposed laterally adjacent to the passage opening 5g. . In this way, the edges 5u of the concave portions 5k, 5l combined with the lower portion 5u of the operating panel 5 are inclined in an outward direction so as to form a combination with the respective concave portions 5k, 5l. A self-centering base for a correspondingly shaped projection 5v is formed in a tapered manner to form a peripheral surface of the projection in contact with the bevel edge region 5u. The cylindrical, non-beveled upper portion 5w of the protruding portion 5v is slightly larger than the cross section of the opening of the combined concave portion 5k, 5l, so that the protruding portion 5v is self-contained in the respective concave portions 5k, 5l Centering to ensure that the portions 5a, 5b are correctly positioned on one side and on the other side the portions 5a, 5b can be pressed together so that they are inseparable from each other in a non-detachable, press-fit manner connection. If desired, it is of course also possible to supplement a press-fit connection by a secure adhesive connection, such as bonding or via a press-fit connection, such as a latch. In order to ensure that the wall thickness of the lower portion 5b is as uniform as possible, a contact hole 5x is formed in the region of the protruding portion 5v into the lower portion 5b.

The plate member 100 shown in Fig. 9 is also a control panel designed as an angular guide plate for use in a rail fastening system, on the one hand for laterally guiding the rails S which are waiting to be fixed and on the other hand A W-shaped spring element (not shown), a tensile clamp, is placed in a fully assembled rail fastening system wherein the tensile clamp exerts the desired elastic retention on the bottom F of the rail S to be secured.

The plate member 100 is divided into a front portion 101 and a rear portion 102 which are combined with the rail S to be fixed, which are prefabricated separately from each other and made of different materials.

The dividing plane T between the portions 101 and 102 extends to cover the length L of the plate member 100 and extends from the upper side 103 of the plate member 100 to the lower side 104, a contact thereon The surface is constructed with the plate member 100 positioned on a concrete sleeper (not shown) which, when in use, constitutes the subsoil carrying the rails.

The first portion 101 employs a fifth of the width B of the plate member 100. The dividing plane T is thus aligned above the height H parallel to the flat supporting surface 105, during which the plate element 100 is placed at the lateral edge of the bottom of the rails S to be fixed, and The formation is on the front side of the first portion 101 joined to the rails S. Only in the upper section joined to the upper side 103, the split plane T bounces back when a protruding portion 106 is deployed in the direction of the second portion 102. With the protruding portion 106, the first portion 101 is disposed on a corresponding recess 107 formed by one of the second portions 102, wherein the height of the protruding portion 106 is measured such that the sides of the plate member 100 are The first portion 101 and the second portion in the edge region The upper side 103 of the segment 102 smoothly penetrates each other.

In contrast, a guiding element 108 is formed on the upper side of the intermediate section of the first portion 101, on the one hand defining the passage opening 109 which forms the first portion, and on the other hand, it constitutes the position to be configured The manipulating portion of the centering ring of the stretching jig on the plate member 100.

Transverse to the guiding element 108, a recessed recessed portion 110, 111 is formed on each side of the guiding element 108 from the upper side 103 into the first portion 101. A notch projection 112, 113 reaches into each of the recessed recessed portions 110, 111, and the recessed projection portion is formed on the front end 114 of the second portion 102 that is coupled to the first portion. In this manner, the first portion 101 and the second portion 102 are connected in an interlocking manner when the plate member 100 is ready for use, when the recessed projections 112, 113 are recessed from the recesses. The connection can be released when the inlet portions 110, 111 are raised and the first portion 101 is removed from the second portion 102.

When the plate member 100 is fully assembled, the flange segments 117, 118 are formed on the lateral wide sides 115, 116 of the second portion 102 and are in the direction of the first portion 101 by the second portion The front end E of the protrusion 102 is configured to be guided laterally to prevent the first portion 101 from sliding relative to the second portion 102 in a longitudinal direction when loaded. At the same time, the flange segments 117, 118 are used as a guide for the simple, correct positioning of the portions 101, 102.

The first portion 101 is constructed of a highly loadable, fiber reinforced plastic material and is particularly designed to be durable in this segment adjacent the contact surface 105 so that it can tolerate high friction loads. This side It is ensured that the first portion 101 reliably assumes the mechanical load that occurs during use.

However, the second portion 102, which extends the width B of the remaining portion and accepts a substantial proportion of the volume of the plate member 100, is constructed of a thin, easily stretchable, less loadable plastic material and thus is low in weight. However, it is statically designed so that it can easily direct the forces occurring during use into the subsoil where it is safely supported.

The division of the plate member 100 enables it to separate the chambers 120 from each other in order to further minimize weight and increase the basis for combining with the first portion 101 to form the chambers 119, 120 and support into the second portion 102. The inherent stability of its front side. In this way, not only is the high rigidity of the second portion ensured but also the contact surface disposed on the bottom side 104 of the plate member 100. This means that the load distribution that occurs there covers a large area. Therefore, premature wear associated with mechanical loads, particularly frictional loads, on small flat sections is reduced.

In order to support the interlock between the first and second portions 101, 102 when the plate member 100 is assembled and ready for use, a protruding portion can be formed on the first portion 101, the first portion 101 engaging with The smallest movement opens before entering the chambers 119, 120.

If one of the portions 101, 102 of the plate member 100 is worn, the associated portion 101, 102 can be replaced independently of the others.
