The invention provides a system for fastening a rail in place and a rail fastener which, while being simple to install, allow a large measure of freedom in the production of the components required and at the same time have great practical utility. To this end a system according to the invention for fastening a rail to a fixed bottom support comprises: a base plate produced from a plastics material, an intermediate layer which is arranged between the base plate and the fixed bottom support, a carrier plate which is arranged between the intermediate layer and the bottom support, a resilient member to hold down the rail which is to be fastened in place, a clamping bolt to brace the resilient member against the base plate, and a fastening member for fastening the base plate to the fixed bottom support.

A rail securing system comprising at least one angle guide plate allows a perfect retention of the tension clamp in its pre-assembly position and facilitates final assembly. The angle guide plate has recess, which is designed as a seat for a free end section of a spring arm of a tension clamp to be mounted on the angle guide plate, wherein the recess engages around the end section by less than half of its circumference. The transition between the recess and the section of the angle guide plate which follows on from the recess in the direction of the rail is formed such as to be free of any abrupt change, so that the tension clamp can be pushed in a simple manner on the angle guide plate into its assembly position.

The invention relates to a support for a system for fastening a rail on a substrate, having an angle bracket, which has a base section with a contact surface associated with the respective substrate, also having a supporting section, standing on the base section, which on its free front side associated with the rail to be fastened has a bearing surface, and also having a through hole formed in the base section for inserting a fastening element intended for fixing the angle bracket on the substrate. With such a support reliable support of the rail in service, also with greater tolerance for positioning the individual components, according to the invention is ensured by the fact that the through hole at least in a direction aligned parallel to the contact surface has an over-measure in relation to the circumference of the part, in the assembled condition sitting in the through hole, of the fastening element and by the fact that an additional locking piece, cooperating with the fastening element for fixing the angle bracket in a particular relative position obtained by a relative movement of fastening element and angle bracket, is also provided.

For achieving improved securing effect in use with oil or wax coated contact surfaces, a self-locking resilient or non-resilient element, such as a spring-ring or a washer, has wall-like protrusions extending on each major surface from the inner to the outer boundary, and recesses lying therebetween, the protrusions each having a plateau-like upper surface which, viewed in cross-section along the peripheral direction of the element, is curved concavely in order to form edges lying in the region of the plateau boundaries, the edges being formed as scraping edges. The wall-like protrusions extend radially in a zig-zag manner from the inner boundary to the outer boundary of each major surface, and each of the recesses lying between the protrusions forms a zig-zag-shaped continuous channel, open in the region of the inner and outer boundaries in order to achieve a drainage effect.

A rail fastening arrangement in which a rail for a rail vehicle is fastened to a base, and to a shim. The rail fastening arrangement includes two guide plates, of which one guide plate respectively is associated with one of the longitudinal sides of the rail, and a shim which is arranged between the base and the rail. The shim, at its top, has a contact area on which the rail is supported, and, at its bottom, has a supporting surface by way of which the shim is supported on the base. The contact area and the supporting surface of the shim, viewed in a section located transversely to the longitudinal extension of the rail, enclose an acute angle. The edge at which the shim is thinner is arranged beneath the rail, fastening of rails oriented at a cant relative to the vertical in the region of points.

The present invention relates to a plastic dowel for the fastening of a rail on a solid substrate. The plastic dowel includes an opening, an 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.
摘要:
A system and a method for fastening a rail to a substrate, with a guide plate for laterally guiding the rail that has a standing surface associated with the substrate, a support element to support the guide plate in the assembly position, a spring element supported on the guide plate and at least one spring arm for exerting a resilient holding force onto the foot of the rail, and a tensioning means for tensioning the spring element. The fastening can be assembled in that the support element has a support lug supported on the substrate in the assembly position to reach under the standing surface of the guide plate in a way that the guide plate is supported on the substrate via the support lug in the region where the guide plate and support lug overlap.
