摘要:
The invention relates to a method which enables sleepers to be produced for the railway track superstructure having optimised performance characteristics, in a reliable and cost-effective manner. The method according to the invention provides the following production steps: a) providing a mixture 10-60 % mass of which consists of a granulate of a plastic, which is deformable by applying heat, and the remainder of which consists of a sand having a bulk density of 1.4-2.0 g/cm3; b) heating the mixture to a temperature of 150-200 ° C.; c) pouring the mixture into a press mould reproducing the sleeper; d) pressing the mixture in the mould at a pressing pressure measured in the mixture of 1-5 MPa over a pressing period of up to 60 minutes; and e) removing the sleeper from the mould.

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 system for fastening a rail on a subsurface, includes a support plate having a contact surface, and at least one guide plate that is seated on said support plate and has a passage opening for a clamping element, which leads from the free top side thereof to the bottom side thereof. The clamping element is guided through the passage opening and is fixedly connected to the subsurface. A latching connection between the support plate and the guide plate is formed in the region of the passage opening by at least one latch arm. The latch arm engages through said passage opening and has a latch projection which interacts in an interlocking manner with a stop formed on said guide plate. A recess is molded into the circumferential surface delimiting said passage opening of said guide plate, in which recess the respectively associated latch arm is seated.

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).

A system for a screwless rail fastening includes a spring element and a supporting collar. The spring element has a bearing section, a curved section, a holding-down section, aligned in the opposite direction to the bearing section, a curved section curved in the direction of the bearing section, and a locking section aligned transversally to the bearing section. The supporting collar includes a fastening section for retaining the supporting collar on the foundation, a carrier section supported by the fastening section, a bearing recess formed on the carrier section for mounting of the bearing section, and a locking head supported by the carrier section on which a counter-bearing for the locking section is formed so that the locking section is retained in a position relative to the bearing section of the spring element.

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.
