  • plate elements of the type in question are made of plastic usually made by injection molding. Even if plastic plate elements have prevailed in practice, there is a fundamental problem in the fact that the guide plates, shims or ribbed plates, for example, are comparatively massive parts with great wall thicknesses and material volumes. According to the existing understanding, this massive design is necessary so that the plate elements can absorb the high forces that occur in practical use and offer enough space to support the rail or the other elements of a rail fastening system, such as the respective spring element.
  • the object of the invention was to create a guide plate which can be manufactured in a particularly simple, cost-effective manner and which has optimal usage properties.
  • a plate element designed as a guide plate according to the invention is a guide plate which is provided to laterally guide the respective rail to be supported in a rail fastening point. Because of their comparably large volume and the high local loads that such guide plates have to endure, the advantages of the design according to the invention have a particularly favorable effect on guide plates for rail fastenings.

  • a plate element according to the invention designed as a guide plate is thus characterized in that the two or more parts from which it is composed are not already joined in a completed process step when the plate element is produced in the tool used for this purpose, as is the case, for example, in an injection molding process Production would be possible, but that the parts of the plate element are joined together in a separate operation outside of the tool in which they were produced.

  • the parting plane formed between the two parts is at least partially aligned parallel and at a distance from a support surface of the plate element with which the plate element stands on a substrate in the position of use. This can be useful, for example, when a lower wear-resistant plate half resting on the respective substrate is combined with a second plate half lying on it, which is made from a complex formable and thus suitable for the formation of molded parts required on the top of the plate element, but from one less wear-resistant material is made.
  • a guide plate for laterally guiding a rail can be made of a highly wear-resistant material in its section coming into direct contact with the lateral edge of the foot of the rail to be guided, while the section of the guide plate made independently of the first section consists of a lighter and there is more malleable material, which allows a lower weight and a complex shape, which ensures a sufficiently high dimensional stability despite the lower strength of the material of the second section.
  • the particular advantage of the invention is that by dividing a plate element according to the invention designed as a guide plate into at least two parts, shorter cycle times result in production. This is especially true when, as in a guide plate according to the invention, the parts of the plate element are made of plastic, since the production time required for the injection molding production of a plastic part is the square of the wall thickness of the respective part. Thus, when proceeding in one process cycle in a two-component injection molding tool, both parts can be produced in parallel, so that there is a significant reduction in the waiting times required between filling the mold and solidification.
  • the individual parts of a plate element according to the invention can be produced together in one tool or in different tools before assembly. Simultaneous production in one tool can be useful if the parts are to be produced from materials that are identical or at least similar in terms of their processability. This is the case, for example, when the parts of a plate element according to the invention are made from plastic materials to which reinforcing fibers are added if necessary in order to ensure the required strengths.

It can be useful if a receptacle is formed in one part in which the other part sits.
  • the receptacle can be shaped in such a way that the part seated in it is completely surrounded by the material of the other part except for an outer surface.

  • the outer part protects the other part seated in its receptacle against environmental influences, while the part seated in the receptacle with its outer surface forms the support with which the The relevant plate element lies on the subsurface on which the respective rail fastening point is erected.
  • the parts forming a plate element according to the invention are shaped in such a way that they interlock in sections.

  • the height of the projection 106 is dimensioned such that in the lateral edge regions of the plate element 100 the top side 103 of the first part 101 and second part 102 merge into one another without jumps.
  • a guide element 108 is formed on the upper side thereof, which on the one hand delimits the through opening 109 formed in the first part and on the other hand forms a guide for the central loop of the tensioning clamp to be arranged on the plate element 100.
  • a latching recess 110, 111 is formed in the first part 101 from the top 103 on both sides of the guide element 108.
  • a latching projection 112, 113 which is formed on the end face 114 of the second part 102 assigned to the first part, engages in each of these latching recesses 110, 111.
  • the first part 101 and the second part 102 are positively connected to one another in the ready-to-use state of the plate element 100, this connection being able to be released in that the latching projections 112, 113 are lifted from the latching recesses 110, 111 and the first part 101 from second part 102 is withdrawn.
  • cheek portions 117, 118 projecting in the direction of the first part 101 from the end face E of the second part 102 form a lateral guide which prevents the first part 101 from being underneath the lateral broad sides 115, 116 of the second part 102
  • the load moves relative to the second part in the longitudinal direction L.
  • the cheek sections 117, 118 serve as positioning aids for simply aligning the parts 101, 102 in the correct position.
  • the first part 101 is formed from a highly resilient, fiber-reinforced plastic and, in particular, is solid in its section adjoining the contact surface 105, so that it can withstand high frictional loads. In this way it is ensured that the first part 101 reliably absorbs the mechanical loads that occur during use.
  • the second part 102 which extends over the remainder of the width B and takes up the vast majority of the volume of the plate element 100, is, on the other hand, formed from an easily malleable, less resilient plastic of low density and associated low weight, but is statically designed so that it forces occurring during use can be safely diverted into the ground against which it is supported.
  • the division of the plate element 100 into two parts allows chambers 119, 120 and struts to be formed in the second part 102, which separate the chambers 120 from one another, to further minimize the weight and increase its dimensional rigidity, starting from its end face assigned to the first part 101.
  • the second part 102 not only is a high degree of rigidity of the second part 102 ensured, but it is also closed to the support surface present on the underside 104 of the plate element 100.
  • the loads that occur there are thus distributed over a large area. Accordingly, the risk of premature wear that would otherwise be associated with the concentration of mechanical, in particular frictional loads, on small surface sections is reduced.
  • projections can be formed on the first part 101, with which the first part 101 engages with minimized play in the end openings of the chambers 119, 120 when the plate element 100 is assembled ready for use.
  • the respective part 101, 102 can be replaced independently of the other.
