Abstract: 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.

Abstract: 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.

Abstract: A system and an intermediate element for a system for fixing a rail for a rail vehicle onto a foundation. The intermediate element is arranged between an end section of a spring element and the rail such that the spring element exerts a retaining force on the rail by means of the intermediate element. The intermediate element has a supporting surface, on which the end section of the spring element rests during use, and a contact surface, with which the intermediate element sits on the rail during use. The intermediate element is elastically resilient in an active direction from the supporting surface towards the contact surface.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A screw anchor for concrete attachment to a railroad tie or solid track comprises external threads (16) disposed on the exterior of the screw anchor (10) and internal threads (18) disposed inside the screw anchor (10) for force-fitted connecting to a fastening element (30), wherein the screw anchor (10) comprises two sections (12, 14) adjacent to one another in the longitudinal direction, the first section (12) having a substantially cylindrical external shape and the second section (14) having a substantially conical external shape, and wherein the second section (14) is disposed between the first section (12) and an inlet opening (26) for the fastening element (30).

Abstract: The invention relates to a system for securing a rail, including a guide plate for providing lateral support for the rail to be secured, a spring element supported on the guide plate and having at least one spring arm exerting an elastic retaining force on the base of the rail, and tensioning means for tensioning the spring element. Such a system allows an optimally secure support of the rail even in the case of a level ground having no indentations or stop shoulders, whilst being easy to handle and having only a small number of components to be mounted in each case, by providing a support angle which may be connected to the solid ground and which has a bearing surface against which the guide plate rests on the side facing away from the rail base. According to the invention the support angles are made from a plastic material, in order to facilitate assembly and improve the function of the support angles in practical use.

Abstract: 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).
