摘要:
Screw dowel for concreting into a railway sleeper or ballastless track and frictionally connecting to a sleeper screw, containing a threaded portion (14) with external thread flights (18) arranged on the outside of the screw dowel (10) and with internal thread flights (19) arranged on the inside of the screw dowel; and an upper subportion (16) without external thread that is situated close to the dowel opening (26) in the installed state; the screw dowel containing two constituent parts made of different materials, namely a basic body made of plastic and a cylindrical ring (20) made of a steel material and mounted with a form fit and/or force fit.
摘要:
A system for fastening a rail to a solid foundation, and a method for renovating a rail-fastening point. The system and the method allow a fastening point for a rail to be easily and economically renovated in such a way that a permanently reliable function of the renovated fastening is then ensured again while the worn support section remains. The system for fastening a rail to a solid ground foundation includes: a layer formed by a compensating mass applied to the support section; a base plate resting on the layer and extending over the support section, upon which the rail is supported in the finally installed state; a spring element for exerting a resilient elastic retention force on the rail; and a clamping element that can be anchored in the solid foundation for clamping the spring element.

An elastic tensioning clamp made of spring steel for rail fixation comprises a central loop (44) having two inner legs (46) connected by an arc-shaped central portion (48) as well as nooses (42) connected to the inner legs (46) of the central loop (44) and running towards the free ends (50) of the tensioning clamp (40). The nooses (42) are formed so as to have, in the unloaded state, a maximum height (H) of at least 20 mm above the upper plane (E2) of the central loop (44) in the region of the two inner legs (46).
摘要:
The present invention relates to an angular guide plate (4) and to a system for fastening rails for rail vehicles, which angular guide plate (4) and system are equipped with a supporting surface (13) via which the angular guide plate (4) is positioned on a solid foundation in its assembly position, in particular in a system in which a spring element (6) for applying the required holding force to the rail (2) is supported on the angular guide plate (4) in the assembly position. The angular guide plate (4) according to the invention allows the abrasive wear of angular guide plate (4) or foundation (3) that occurs in the prior art to be minimised. This is achieved in that the supporting surface (13) is overlaid at least in certain sections with a resilient layer (5).

A system for fixing a rail onto a foundation comprises a spring element, which can be clamped against a foundation by means of a clamping element, with at least one spring arm and an adapter piece. The adapter piece has a holder, in which an end section of the spring arm of the spring element sits, and a contact surface section formed at its periphery, with which, when the system is assembled, it sits on the rail foot of the rail to be fixed, such that the elastic retaining force exerted by the spring element is transferred onto the rail foot.

摘要:
A system for fastening a rail on a substrate includes a base plate, molded into which is a central portion, the width of which is adapted to the width of the rail foot of the rail to be fastened, with at least one fastening element for connecting the base plate to the substrate. The at least one tensioning element is provided for holding down the rail on the base plate. The system provides a fastening system allowing fastening of rails that satisfies modern requirements with the additional benefit of low production costs and simple assembly, while maintaining the basic configuration of the base plate provided and using simple means.
摘要:
A system for fixing a rail onto a foundation and to a guide plate. The system comprises a spring element, with at least one spring arm, which can be clamped against the foundation by means of a clamping element, an adapter piece, with a contact surface section, which sits on an end section of the spring arm, and a guide plate. The guide plate has a contact surface for the rail foot and a sliding surface which adjoins the contact surface via which the adapter piece can be moved from a pre-assembly position in which it sits on the guide plate with its contact surface section to an assembly position in which it is seated, with its contact surface section, on the rail foot of the rail to be fixed. A stop is provided on the sliding surface against which the adapter piece rests in the pre-assembly position.
