Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a plate member for guiding a rail,

The present invention relates to a plate member made of a plastic material and provided for guiding a rail at a rail anchorage point. The invention also relates to a method of manufacturing such a plate member.

BACKGROUND OF THE INVENTION [0002] Recent rail anchoring points, particularly used in the field of heavy-duty vehicles or high-speed railways, typically include various plate-shaped components made of a plastic material used to support and guide the rail to be fixed.

These plate-shaped rail-securing components include a "steering plate", a "packing plate", an "angled guide plate", a "spacer plate", a "pressure distribution plate" Quot; rib plate "

Indeed, the steering plates of the type in question here have dual functions as part of a system for securing rail rails. On the one hand, the plates are used for the lateral guidance of the rails and, when fully assembled on the track, absorb lateral forces on the plates, which force each time the supported rails ride over their respective anchor points Occurs. On the other hand, a spring element is generally supported and guided over the steering plate, which causes the spring resilient force to act on the rails against each subsoil.

In order to carry out this dual function, known steering plates generally have a contact surface which acts against the base of the rail to be fixed in a fully assembled position, and functions as a rail when the railway vehicle is passed against this contact surface. The steering plates are either fixed to a support surface which is opposite the contact surface and which is formed on the side of the steering plate which is away from the rails and which acts against the shoulder formed on each subsoil, Is supported by the member against the subsoil supporting the respective rails.

If the steering plate is formed as an "angle guide plate ", additional indentations may be formed in the lower portion of the steering plate extending in the longitudinal direction of the steering plate, which, when assembled, It is located in a fastening manner. As such, the position of the steering plate is fixed across the longitudinal extension of the rails.

In order to simultaneously press the springs disposed on the steering plate against the subsoil, the passage openings guided from the upper side to the lower side are regularly formed on the normal steering plates. A tensioning member required to press each spring member is inserted through this passage opening to engage the tension members to the underlying soil supporting the rails. In this connection, in general, a screw or screw bolt is used as the tension member, which can be coupled to the screw anchor inserted in the subsoil.

In order to be able to simply transport, store and assemble the steering plate, in addition to the sufficiently high resilience of the type of steering plate of the type of dual function described above, a low weight is basically required. This requirement can be met by a steering plate made of rigid, elastic plastic material. Examples of these types of steering plates are described in DE 102 54 679 B4, DE 41 01 198 C1 and DE 20 2004 020 816 U1.

When the anchoring points formed by this type of rail anchoring system are applied to the rail fixation systems of the type of the object that are intended to deliver the resulting load when the anchoring points are traversed equally in the gravity direction over a large area over the constructed anchor soil, , Spacer plates, pressure distribution plates and rib plates are used. For this purpose, it may be necessary to extend over the width of at least the base of the rails taken across the longitudinal extension of the rails relative to the local conditions and the assembling positions of the plates in each rail fixing system, do. The plates are then placed directly on each respective subsoil or supported by one or more intermediate layers on the subsoil. A package of intermediate layers consisting of a plurality of layers consisting of different plates and of an elastic material is also formed a. An equal distribution of loads occurring therebetween, on the one hand, and b. On the other hand, the required elasticity for the long life of the rails to be fixed, and the necessary flexible elasticity of the fixing point in the direction of gravity are secured.

Plates with ribs are a special case of plate-shaped parts for fixing the rails. When assembled, two ribs parallel to one another on the free top side and extending longitudinally to the rails to be fixed form a contact area where the rails to be fixed by the rail base are located when they are assembled between the rails. When the ribs guide the rail base in the transverse direction and the anchor points formed by the respective rail fastening systems are traversed, the ribs are spaced from one another to take up the transverse forces that occur.

In fact, plate members composed of this type of plastic material are generally manufactured by injection molding. Even if the plate member of the plastic material is actually used, there is a fundamental problem in that relatively large parts having large wall thickness and material volume are used, for example, in steering plates, packing plates or rib plates. This large configuration is necessary to provide a sufficient area for the plate members to absorb large forces generated during actual operation and to support rails or other members of the rail fastening system, such as, for example, respective spring members .

Depending on the large wall thickness and the material volume, a relatively long machining time is required to manufacture a known plate member. It also has a negative impact on stiffness due to blending and cooling problems. Thus, in addition to the long machining time, an expensive process is required to ensure optimum distribution of stiffness over the entire volume of the plate member, and in particular to avoid loss of stability of the weld seam region formed by injection molding.

However, it is possible to minimize the volume of material required by a fine filigree adapted to the actual load. However, this type of optimal shape also results in a complicated configuration, which also typically involves high demands in industrial manufacturing through injection molding.

With respect to the background of the above-described prior art, it is an object of the present invention to provide a plate member which can be manufactured particularly simply and cost-effectively and has optimal characteristics. A method of manufacturing this type of plate member is also provided.

This object is achieved by a plate member constructed according to claim 1 on the side of the plate member.

In a method aspect, a solution to the above-described object according to the present invention is achieved by a method according to claim 15 of the present invention which is carried out in the manufacture of a plate member according to the present invention.

Effective embodiments and variations of the present invention are provided in the dependent claims and will be described in more detail below in accordance with the general concept of the present invention.

The plate members according to the invention for fixing the rails to the rail anchoring points thus consist of at least two parts which are spatially separated from each other and tightly connected to one another.

A method according to the invention for manufacturing a plate member of this type comprises the following steps:

- fabricating plate member parts in spatially separate tools;

- coupling the parts to the plate member.

Thus, a plate member for rail fixing is produced, which consists of at least two parts which are tightly connected to one another and which are initially assembled in a further working step, which is pre-manufactured and then the parts are permanently connected tightly.

Thus, the plate member according to the invention can be constructed so as not to be assembled during the manufacture of the plate element, for example in a tool used in a finished process, which is possible in injection molding manufacture, but assembles parts already made in separate steps, Features two or more parts.

The division between the individual parts of the plate member according to the present invention can be selected to perform the designated function in an optimal manner with the individual parts respectively coupled to the plate member. In addition, it is important that the dividing surface formed between the two parts is at least parallel to the section and located at a certain distance from the contact surface of the plate member, and that by this contact surface, when the plate member is in the use position, Lt; / RTI > For example, this can be achieved by forming a second plate half, made of a material that is required to form the necessary molded parts on the upper side of the plate member, but less abrasive, Lt; / RTI > may be useful.

Alternatively, the division between the individual parts of the plate member according to the invention may also extend from the lower side to the upper side of the plate member. Thus, for example, the steering plate for lateral guidance of the rails of the sections in direct contact with the lateral edges of the base of the rail to be guided can be made of a material that is much more abrasion resistant and the steering plate section, which is manufactured separately from the first section It can be made of a lighter and more flexible material, which makes it lighter in weight and can produce complex shapes, thus ensuring a sufficiently high inherent stability, even though the stiffness of the material of the second section is weaker.

A particular advantage of the present invention is that the division of the plate member according to the invention into at least two parts reduces the manufacturing cycle time. This is especially so when the parts of the plate member are made of plastic material and the manufacturing time required for injection molding production of the plastic part is quadratically related to the wall thickness of the part. Thus, in a process cycle as part of a method according to the present invention in a two component injection-molding tool, both parts can be manufactured simultaneously, which can significantly reduce the required waiting time between filling and solidifying the mold .

The individual parts of the plate member according to the invention can then be fabricated together in a tool or several tools before assembly. Simultaneous manufacture in a tool can be convenient when components are manufactured using a molding process with the same processability or at least similar materials. This is the case, for example, when the parts of the plate member according to the invention are made of reinforcing fibers and plastic materials, which are allocated on demand, in order to ensure the requisite stiffness. In this case, the tools are used when the individual parts are manufactured separately from each other, for example when the number of cavities corresponds to the number of parts to be formed.

Of course, the parts of the plate member according to the invention can be manufactured in other tools. According to this method, the material used to manufacture the parts to be used is used to suit the load applied to these parts in actual use. For example, it can be considered that the parts of the plate which are actually subjected to a large load are made of a high-strength plastic material, and that other parts on the fine filigree-shaped member can be made of, for example, a well- . From a plastic material having greater corrosion resistance than other parts on the relatively complicated molded part to guide the collected liquid to the steering plate in a predetermined manner or to guide the elastic member, It may be considered to manufacture a part of the plate member according to the present invention in which wear is generated under a predetermined condition and a load is applied.

Significant time and cost savings achieved with the arrangement according to the invention and the manufacturing process enabled thereby also have a significant effect on the plate member provided as a normal use in which the first part and at least one additional part are made of different materials .

Other materials may be further combined with each other by separating and manufacturing the parts constituting the plate member according to the present invention. For a load that is expected to be particularly large, it means that one part can be made of a metal material such as cast aluminum or cast iron, and the other part can be made of a plastic material.

The plate member according to the present invention, which is usually made of a plastic material, is generally a thermoplastic plastic material. For example, these materials include polyamide (PA), polypropylene (PP), polyethylene terephthalate (PET), or general products that have been polymerized or polycondensated.

The components of the plate member according to the present invention can be firmly connected to one another by force-fit, positive engagement or adhesive bonding, or by the combination or mixing of these connection types.

The manner in which the parts of the plate member according to the invention are combined can also be selected according to the technique used for the actual occurring load or the coupling or connection used to join the pre-manufactured parts together to the plate member according to the invention . Thus, it may be convenient to have an indent in one part where the other part is located. The indent portion can be formed such that the part located in the recessed portion is completely surrounded to the outer surface by the material of the other part.

For example, this type of arrangement is advantageous in that the parts located at the indentation of the other part are made of a plastic material with high abrasion resistance and the other parts are highly resistant to environmental factors such as UV light, moisture and temperature, It can be useful when it is composed of branches. In this case, the outer part protects the other parts located in the indentation from environmental factors, and the outer surface of the part located in the indentation forms a layer where the associated plate member rests on the subsoil where each rail anchoring point is built.

The parts forming the plate member according to the present invention may also be formed to mutually engage in the sections. To this end, at least one recess may be formed on one part to engage with the protrusion of the other part. The projection of one part may be formed as a notch that engages the recess of the other part. For this purpose, the recess may be formed as an indentation and the notches of the protrusions of the other parts are fastened together. The protrusion of one part is also somewhat larger than the recess of the other part, so that the protrusion can be pressed into the recess and then press-fitted.

Another possibility to form a solid connection between the parts of the plate member is to form an adhesive bond. For this purpose, the parts may be joined together and welded (e.g., ultrasonic welding, friction welding or heating element welding) or soldered. On the one hand, for example, a layer may be provided which affects the adhesive connection with each of the other parts, while each of the other parts may be provided automatically or with the aid of radiant energy such as heat, UV light, Affects other parts that come into contact with other parts under influence. These types of layers can be formed, for example, by injection molding again with the film inserted into the tool of one part and the material of the associated part activated after molding of the associated part.

Screws, nails, rivets, brackets, and the like. Special connections can of course also be used to hold the plate members according to the invention together. It is also conceivable to use conventional coupling and connection techniques such as clinching and clipping. Using a resolvable connection means having the advantage that parts can be easily separated from each other if it is necessary for the parts to be replaced by wear or if it is necessary for the entire plate member to be discarded in an environmentally friendly manner.

During assembly, the precise placement of the components of the plate member according to the present invention can be supported by parts that are articulated together by a hinge. The parts can then be pivoted on top of one another about an axis formed by the hinge. For this purpose, the hinge can be formed as a resultant film hinge when the parts are manufactured. To this end, the parts forming the plate member according to the invention can be made of a plastic material in the same tool separated from one another by one cavity per part, the cavities being connected to each other by a sufficiently narrow channel, A film hinge is articulated. It is conceivable that the spindle provided to fill the molding cavity during the injection molding manufacturing of the plate member can be configured to form a joint in which the parts can be folded together after molding of the parts.

In addition, the precise placement of the components can also be supported by placement guides such as molding marks, pins, etc., provided for precise placement of a component on other components.

It is particularly effective if the plate members constructed in accordance with the present invention are provided so as to guide the rails which are respectively supported laterally at the rail anchor points. The advantages of the design of this type of plate member in accordance with the invention due to the large volume and high localized loads that this type of steering plate has to withstand are particularly desirable for securing the rails. Thus, it is possible to adapt to the mechanical and other characteristics of the individual sections of the steering plates under the conditions actually encountered, particularly by the multiple components of the steering plate provided in accordance with the present invention.

The packing plates and rib plates can also be manufactured in a cost-saving manner in accordance with the invention, and such packing plates or rib plates can occupy a large volume, perform the necessary supporting and guiding functions and minimize weight Can be complicatedly formed.

Thus, the present invention provides a plate member for securing rails for railway cars, which can be manufactured particularly cost-effectively. This aspect is particularly applicable if the parts of the plate member are made of plastic material, since the cycle time can be significantly reduced according to the invention. The positive effect produced from the plastic material is that an improved manufacturing quality is achieved through a reduced volume of individual components relative to the volume of the entire plate member, and this manufacturing quality is characterized by minimal delay and also minimized shrinkage. Moreover, according to the present invention, a cost-saving, pre-manufactured standardized basic part can be combined with a part adapted individually to a large number of related conditions, thus significant cost savings can be achieved. For example, if the plate member according to the present invention is a steering plate, the same lower part can always be combined with the upper part, which is optimally adapted to the type of elastic member to be respectively supported on the steering plate.

The steering plates 1 to 5 are part of a fixing system for fixing a rail S for a railway vehicle. The individual components of this type of fastening system are well known and are described, for example, in the publications already described above. For example, fixed systems of this type are provided by applicants with the designation "W14", "W21", "300" and "304".

With this type of anchoring system, the anchoring point is formed on a tie or plate made of concrete, for example forming the subsoil U shown only partially in Fig. Thus, the subsoil U belongs to a fixed point formed by using the steering plates 1 to 5 according to the present invention.

The fastening system comprises an elastic member which is generally omega-shaped and is constructed on the basis of a conventional tensioning clamp, the tensioning member comprising a tension member for pressing the elastic member against each of the subsoil and one of the steering plates 1 to 5 Screw or screw bolt. Of course, additional members may also belong to such systems as packing plates, elastic sheets, etc. to achieve a constant elasticity and optimal pressure distribution of each anchor point.

For clarity of components generally belonging to the rail fixing system, only the steering plates 1 to 5 are shown and the subsoil U is shown in part.

The steering plates 1 to 5 are each constructed on the basis of a known " angle guide plate " and have a rectangular shape in plan view. The contact surfaces 1c, 2c, 3c, 4c and 5c are formed so as to extend over the length L of the steering plates 1 to 5, respectively, on one longitudinal side surface, whereby the respective steering plates 1 to 5 Act on the foot of the rail S to be fixed to the respective fixing points when fully assembled.

The support surfaces 1d, 2d, 3d, 4d and 5d extend over the length L of each of the steering plates 1 to 5 at the opposite longitudinal side surfaces of the respective steering plates 1 to 5 Whereby when the steering plates 1 to 5 are fully assembled, they are supported with respect to the shoulder 7, which is molded with respect to the subsoil U supporting the steering plate 1. The subsoil U, which is only partially shown, is formed by, for example, a concrete tie, or a concrete plate or other fixture.

When the flat contact surfaces 1e, 2e, 3e, 4e and 5e are respectively formed and completely assembled on the lower side of the steering plates 1 to 5 associated with the subsoil U, the steering plates 1 to 5 Is placed on the flat contact surface (8) of the subsoil (U).

The indentations 1f, 2f, 3f, 4f, and 5f are formed in the region where the transition occurs between the contact surfaces 1e, 2e, 3e, 4e, 5e and the side-direction supporting surfaces 1d, 2d, 3d, 4d, Is formed in a downward direction extending over the length L of each of the steering plates 1 to 5 and is arranged in a correspondingly formed groove 9 of the subsoil U. Thus, the position of the steering plate 1 in the transverse direction Q of the rail S is fixed to the subsoil U in such a manner as to be mutually engaged.

The passage openings 1g, 2g, 3g, 4g and 5g located at the center and extending from the upper side to the lower side of the steering plates 1 to 5 are also formed in the steering plates 1 to 5, A tension member for pressing a spring element (not shown) supported on the upper side of the steering plate 1 is guided through the steering plate when the fastening system is assembled.

The upper side surfaces of the steering plates 1 to 5 are formed with molding elements for guiding the center loops of the spring elements and for discharging water and other liquid that can be collected on the steering plate 1. [

As described above, the steering plates 1 to 5 are composed of the first parts 1a, 2a, 3a, 4a and 5a and the second parts 1b, 2b, 3b, 4b and 5b, respectively. These two parts 1a to 5a (1b to 5b) are pre-manufactured in a space separated into spaces in an injection molding tool, not shown here, respectively, of a fiber-reinforced plastic material and then joined to the respective steering plates 1 to 5 do.

The plastic material of the upper parts 1a to 5a of each of the steering plates 1 to 5 shown upward in the assembling position (Fig. 1) guides the elastic elements located there in each case, Are molded to form molding elements formed on the upper side of each of the steering plates 1 to 5 provided for discharging. On the contrary, when assembled (Fig. 1), the plastic material of the lower parts 1b-5b of the steering plates 1 to 5 located on the lower soil layer U is formed of the lower part 1b of the steered plates 1-5 B) are adjusted to provide a high degree of resistance to corrosion wear.

In the steering plate 1 shown in Fig. 1, a divided surface 1i is formed parallel to the contact surface 1e between the two parts 1a and 1b in each case and the support surface 1d connected to the contact surface 1e And extends over the entire width (B) and length (L) of the steering plate (1). When the two parts 1a and 1b of the steering plate 1 are assembled (FIG. 1), when they are placed on the undergarment U and assembled, the upper part 1a of the steering plate 1 The upper part of the lower part 1b of the steering plate 1, which is joined to the lower part 1b. The adhesive effect of the adhesive film can be activated, for example, by the addition of heat or radiation energy.

In the steering plate 2 shown in Fig. 2, the receiving member 2j is formed into the upper part 2a, which is disposed in such a manner that the second parts 2b are engaged with each other. As such, the second part 2b is laterally surrounded at its upper side by the material of the first part 2a and its lower side joined with the subsoil U forms a contact surface 2e, 2) are placed on top of the subsoil (U). The second component 2b can be pressed into the receiving member 2j in order to securely and permanently grasp the second component 2b on the receiving member 2j of the first component 2a. As long as the indentation-fastening connection is achieved in this way, bonding can also be carried out.

Contrary to the structure of the steering plate 2, in the steering plate 3 shown in Fig. 3, the housing member 3j is formed in the lower part 3b, and the inside of the housing member 3 The upper part 3a is located. In this case, the large abrasion resistant material of the lower part 3b is less elastic on the side surface and its lower side so that only the upper side of the upper part 3a, on which the molded part necessary to guide the respective elastic elements, And surrounds the well-formed upper part 3a made of plastic or the like. Here, the upper part 3a can also be adhered to the inside of the receiving member 3j of the lower part 3b.

4, the cavities of the injection molding tools are connected together by a channel having a minimum height during the manufacture of the parts 4a, 4b, so that the parts 4a, 4b are connected together by a thin strip after mold disassembly. This strip forms a film hinge 4h which extends beyond the length L of the steering plate 4 and around which the parts 4a and 4b are folded to engage these parts to the steering plate 4. [ As such, in a simple manner, the film hinge 4h enables precise placement of the parts 4a, 4b. The parting surfaces 4i of the parts 4a and 4b extending over the whole width B and the length L of the steering plate 4 are arranged substantially parallel to the contact surface 4e of the steering plate 4 And the dividing surface moves down in the region of the indentation 4d.

The connection between the parts 4a, 4b of the steering plate 4 shown in Figs. 5 and 6 is ensured by positive engagement and press-fit fastening.

For this purpose, slit-shaped recesses 4k, 4l, 4m, 4n are formed in the upper part 4a extending from the upper side to the lower side of the upper part and extending in the longitudinal direction of the steering plate 4. [ Here, the pair of recesses 4k and 4l are formed in the cross-section of the upper part 4a provided on the other side of the pair of corresponding recesses 4m and 4n, Are formed at a predetermined distance from each other in the cross section of the upper part (4a) provided on one side surface adjacent to each other. The recesses 4k to 4n each have a sharp edge 4k to 4n protruding from each of the recesses 4k to 4n extending in each case along the edge of the recesses 4k to 4n converted from the adjacent recesses 4k to 4n, And an indentation 4o of the edge. A protrusion 4p is formed on the lower part of the lower part 4b of the upper part 4a in the region of the recesses 4k to 4n on the lower side thereof and the lateral surface of the protrusion is formed in a conical tapered shape.

A hollow portion 4q is formed in the region of the lower part 4b of the steering plate 4 coupled to the recesses 4k to 4n so as to adapt to the shape of the projection 4p, When the steering plate 4 is fully assembled, the projections 4p are engaged with each other. The projecting portion 4p and the hollow portion 4q thus form a positioning guide, whereby the correct positioning of the parts 4a, 4b is additionally supported.

Notch protrusions 4r and 4s are formed on the lower part 4b of the hollow part 4q of the lower part 4b and these notch protrusions 4r and 4s are formed in the lower part 4b when the steering plate 4 is fully assembled , Which in each case are fastened to the recesses 4k to 4n coupled to the protrusions. With the notches 4t, the notches are fastened in an interlocking manner to the indentations 4o of the respective recesses 4k to 4n so that the lower part 4b is fixedly held above the upper part 4a.

In the steering plate 5 shown in Figs. 7 and 8, the circular recesses 5k, 51 are provided in the passage opening 5g in the width direction of the passage opening 5g of each section of the upper part 4a, Structure. As such, the edge 5u of the recesses 5k, 51 coupled to the lower part 5u of the steering plate 5 has a correspondingly shaped protrusion 5v, 5l coupled to each recess 5k, Is circumferentially beveled so that an auto-centering sheet for the beveled edge region 5u is formed, and the peripheral surface of the protrusion contacting the beveled edge region 5u is formed in a conical tapered manner. The cylindrical upper section 5w in which the bevel of the projection 5v is not formed is somewhat larger than the cross section of the opening of the coupled recesses 5k and 51 so that the correct arrangement of the parts 5a and 5b, Is ensured by the automatic centering of the protrusions 5v in the first and second protrusions 5k and 5l while the other parts 5a and 5b can be pressed together to fix the parts to each other in a fixed press-fit manner. If desired, the pressure-tight connection can of course be complemented by a rigidly connected connection, such as a connection, or by a press-fit connection, such as latching. A countersink 5x is formed inside the lower portion 5b from the contact surface 5e in the area of the projection 5v in order to ensure the wall thickness of the flat as possible lower portion 5b.

The plate member 100 shown in Fig. 9 also has a steering system (not shown) which is designed as an angle guide plate for use in a transverse inner-rail fixing system of the rail S to be fixed on the one hand and on the other W- Plate and the tension clamp is placed in a fully assembled rail fastening system applying a predetermined resilience force on the base F of the rail S to be fastened.

The plate member 100 is divided into a front part 101 coupled to a rail S to be fixed and a pre-fabricated rear part 102 separated from each other by a different material.

The dividing surface T between the parts 101 and 102 extends from the upper side 103 of the plate member 100 with the contact surface formed to the lower side 104 When the plate member is extended and the plate member is used, the plate member 100 is placed with it on a concrete tie (not shown) forming a subsoil supporting the rail.

The first part 101 is formed at about 1/5 of the width B of the plate member 100. The parting surface T is then formed on the front side of the first part 101 coupled to the rail S and with the plate member 100 with the trailing edge of the base of the rail S to be fixed during use, (H) in parallel with the flat support surface (105) on which the flat support surface (105) is disposed. The dividing surface T is formed only when the protrusion 106 extends in the direction of the second component 102 only in the upper section coupled to the upper side 103 only. The first part 101 is located in the indentation 107 formed corresponding to the second part 102 and the first part 101 is located in the transverse edge area of the plate member 100. In addition, The height of the projection 106 is measured so that the upper side surface 103 of the first component 102 and the upper side surface 103 of the second component 102 flexibly intercommunicate with each other.

In contrast, on the upper side of the middle section of the first part 101, a guide opening 108 is formed and on it, on the one hand, a passage opening 109 formed inside the first part, while the plate member 100, on the other hand, Thereby forming a steering member for the center loop of the tensile clamp disposed above.

Notch recesses 110 and 111 extend from the upper side surface 103 to the first component 101 and extend across the guide member 108 on each side of the guide member 108. Notch protrusions 112 and 113 extend into each of the notch recesses 110 and 111 and these notch protrusions are formed in the front end 114 of the second component 102 coupled to the first component. As such, when the plate member 100 is ready for use, the first part 101 and the second part 102 are connected in an interlocking manner and the notch protrusions 112 and 113 are connected to the notch recesses 110 111, and when the first part 101 is separated from the second part 102, this connection can be released.

When the plate member 100 is fully assembled, it is formed on the lateral light sides 115 and 116 of the second part 102 and extends from the front end E of the second part 102 toward the first part 101 direction The cheek sections 117, 118 protruding from the first part 101 form a transverse guide which, when loaded, prevents the first part 101 from slipping longitudinally relative to the second part. At the same time, the cheek sections 117, 118 act as placement guides for simple, precisely positioned alignment of the components 101,

The first part 101 is also formed of a highly loadable, fiber-reinforced plastic material, and in particular in the section adjacent to the contact surface 105, the first part is rigidly configured to withstand a large frictional load. As such, it is ensured that the first part 101 reliably withstands the mechanical load that occurs during use.

However, the plate member 100 occupies a significantly large volume fraction and the second part 102 extending over the remainder of the width B is easily manufactured with a small thickness of less flexible, less loadable plastic material, Since the weight is small but static, the force generated during use can be easily guided to the subsoil and supported securely.

The division of the plate member 100 further increases the inherent stability based on the front side coupled to the first part 101 to minimize the weight further and form the chambers 119, It is possible to branch to the second part 102 which separates them from each other. Thus, not only the high rigidity of the second part 102 is ensured, but also the adhesion of the second part to the contact surface provided on the lower part 104 of the plate member 100 is ensured. This means that the load generated here is distributed over a large area. Thus, it is possible to reduce the risk of unexpected wear associated with the concentration of mechanical loads, particularly friction loads on small flat sections.

In order to support the interlocking between the first and second parts 101 and 102, protrusions can be formed on the first part 101 and when the plate member 100 is assembled and ready for use, The first part 101 may be coupled together at the front openings of the chambers 119,

If one of the parts 101, 102 of the plate member 100 is worn, then the associated parts 101, 102 can be replaced separately from the others.
