The present invention relates to a plastic dowel for the fastening of a rail on a solid substrate. The plastic dowel includes an opening, and interior, a shank section, and a holding section, which provides at least one circumferential projection around its circumference. The at least one projection protrudes in a radial direction whereby the upper flank of the projection of the holding section assigned to the dowel opening is aligned at an angle of 90°±3° in relation to a longitudinal axis of the plastic dowel.

A fastening point for a rail on a foundation including a bedplate arranged on a support surface of the foundation. The bedplate includes a bearing surface formed on its underside associated with the foundation and also a through-opening, a spring element for exerting an elastic holding-down force on a rail foot and a clamping screw, which braces the spring element against the bedplate. The clamping screw is guided with its threaded shaft through the through-opening of the bedplate. The clamping screw acts with its screw head against the spring element and is screwed into a thread provided in a region of the through-opening of the bedplate. A free space is provided in a region underneath the bedplate in the extension of the through-opening of the bedplate, into which the threaded shaft of the clamping screw can be inserted.

The present invention relates to a base plate for a rail fastening point, in which a rail for a rail vehicle is fastened on a substrate. The base plate includes a main body with a rib structure, which from the underside assigned to the substrate is formed into the main body of the base plate and is formed by ribs and by recesses which surround the ribs and are open to the underside, and to a rail fastening point. The base plate for a rail fastening point can be manufactured in a simple, cost-effective manner and makes it possible to avoid by simple means pressing into a soft substrate. This is achieved in that the base plate additionally includes a cover fastened to the base plate after the manufacture of the main body, which covers the rib structure on the underside of the main body at least in sections.

The invention relates to a plate element (1-5; 100) for fixing a rail (S) in a rail fixing point. The plate element (1-5; 100) can be manufactured according to the invention in a particularly simple and cost-effective manner under optimal usage conditions such that the plate element (1-5; 100) is made up of at least two parts (1a, 2a, 3a, 4a, 5a; 1b, 2b, 3b, 4b, 5b; 101, 102) which are manufactured spatially separate from one another and connected to one another rigidly. In order to manufacture a plate element (1-5) according to the invention the parts (1a, 2a, 3a, 4a, 5a; 1b, 2b, 3b, 4b, 5b; 101, 102) are first generated in a first step in spatially separate tools and in a second step are then joined to the plate element (1-5).
摘要:
The present invention relates to a component for rail fixing systems manufactured from a fibre-reinforced plastics material which consists of a basic plastics material and reinforcement fibres integrated therein. The component for rail fixing systems according to the invention can be manufactured from plastics materials in a cost-effective manner and combines a low weight with a mechanical resilience optimally matching the requirements with the greatest possible level of design freedom. This is achieved by manufacturing the component by using injection moulding compounding and the length of the reinforcement fibres being an average of at least 200 μm.
