摘要:
The present invention relates to a bedplate (UP) for a rail fastening point in which a rail for a rail vehicle is fastened on a foundation, wherein the bedplate (UP) has a main body with a ribbed structure which is formed into the main body of the bedplate (UP) from the underside (10) assigned to the foundation and which is formed by ribs (26) and apertures (27) which are bounded by the ribs (26) and open towards the underside (10), and to a rail fastening point. The bedplate according to the invention for a rail fastening point can be produced in a simple, cost-effective manner and makes it possible with simple means to avoid indentation into a soft foundation. This is achieved in that the bedplate (UP) additionally comprises a covering (34) which is fastened to the bedplate (UP) after the main body has been produced and which at least partially covers the ribbed structure on the underside (10) of the main body.

The invention relates to a fastening point (1) for a rail (2) on a foundation (U). The fastening point comprises a bedplate (3) which is arranged on a support surface (12) of the foundation (U) and which has a bearing surface (7) formed on its underside (6) assigned to the foundation (U) and which also has a through-opening (21,22), said fastening point also comprising a spring element (34,35) for exerting an elastic holding-down force on the rail foot (15), and a clamping screw (27,28) which braces the spring element (34,35) against the bedplate (3), wherein the clamping screw (27,28) is guided by way of its threaded shaft (29,30) through the through-opening (21,22) in the bedplate (3). According to the invention, the clamping screw (27,28) acts by way of its screw head (31,32) against the spring element (34,35), the clamping screw (27,28) being screwed by way of its threaded shaft (29,30) into a thread (25,26) provided in the region of the through-opening (21,22) in the bedplate (3), and there being a clearance (44,45) below the bedplate (3) as an extension of the through-opening (21,22) in the bedplate (3), into which clearance the threaded shaft (29,30) of the clamping screw (27,28) can be introduced by way of its free end.

The present invention relates to a plastic plug (1) for securing a rail on a solid base, said plug having a plug opening (3) for introducing a sleeper bolt (2), a plug internal space (8), a shank section (4) which connects to the plug opening (3) in the longitudinal direction LR of the plastic plug (1), and a holding section (5) which connects to the shank section (4) in the longitudinal direction LR of the plastic plug (1) and is provided on the outside with at least one projection (11) protruding in the radial direction R and running around the circumference. Cracks in the solid base near the surface are avoided by an upper flank (12) of the projection (11) associated with the plug opening (3) at an angle ß1 of 90° ± 3° in relation to the longitudinal axis L of the plastic plug (1).

The invention relates to a component for rail fixing systems, said component being made of a fiber-reinforced plastic which consists of a base plastic and reinforcing fibers incorporated into said base plastic. The component according to the invention can be produced from plastic inexpensively and allows the combination of a low component weight with a mechanical load-bearing capacity which is optimally adapted to the respective requirement while having a wide freedom of design. This is achieved in that the component is produced using the injection molding compounding process, and the length of the reinforcing fibers is at least 200 μm on average.
