摘要:
A system includes a guide plate, a fastening member and a resilient member, for fastening a rail on a solid base. The guide plate serves as a guide for the rail in the horizontal direction and as a stop for movements of the rail in the vertical direction. The guide plate has a contacting surface against which the longitudinal side of the foot of the rail rests. The resilient member which rests on the guide plate exerts substantially no hold-down force on the rail and merely supports the guide plate elastically against the clamping member. The resilient member is of a W-shaped or S-shaped configuration and, in the fitted state, a portion thereof projects sufficiently far over the foot of the rail for it to be retained resiliently by the resilient member if it is moved upwards in the vertical direction.

A screw anchor for concrete attachment in a railway sleeper and to a force-fit connection using a rail screw containing a threaded section with external threads disposed on an exterior of the screw anchor and internal threads disposed in the screw anchor; and an upper partial section without external threads which is disposed in a mounted state close to an anchor opening. The screw anchor utilizes material with high elasticity arranged in the upper partial section, wherein this material, when in a mounted state, forms an elevation which extends in an upward direction over an upper side of an end surface of the upper partial section and reduces a free opening section of the inner chamber of the upper partial section.

The invention relates to a system for fastening a rail to a sleeper with a baseplate, which includes at least one side portion and a bearing surface adjoining the side portion for the rail to be fastened, and with at least one guide plate that sits on the side portion. In order to simplify the installation on the respective sleeper in such a system, the invention provides that the guide plate is held on the baseplate by a catch connection formed in the region of the side portion.

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.

A system for fixing a rail onto a foundation and a support plate intended for such a system. The system comprises a guide plate, a spring element which can be clamped against the foundation by means of a clamping element, sits on the guide plate and in the final mounted system with its free spring arm exerts a retaining force on a rail foot of the rail, and a support plate which is arranged to compensate for height differences between the guide plate and the foundation concerned. The system proposes dividing the support into two parts along a joint line which runs, starting from the one long side of the support plate aligned transverse to the rail to be fixed, at a distance from the one short side to the passage opening and from there intersecting the passage opening in the direction of the short side of the support plate.

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).

The invention provides a base plate, and a fastener equipped with such a base plate, whose weight is minimized and whose stiffness is optimised on the one hand and which is suitable for being supported on an elastic intermediate layer on the other hand. To this end, a base plate according to the invention for fastening a rail to a fixed bottom support has, the base plate being made of a plastics material and a stiffening structure which is formed by ribs and by depressions present between the ribs being formed or molded in the underside of the base plate, which underside is associated with the fixed bottom support, depressions of the stiffening structure being closed off, in accordance with the invention, by a filling material.
摘要:
A base plate for fastening a rail to a fixed bottom support, having a through-opening which runs from the upper side of the base plate to its underside and through which a clamping bolt having a polygonal head is inserted from the underside, forming in the underside, a receptacle, wherein the head of the clamping bolt is seated. Each side-face of the bolt head has a face for contact formed on the circumferential wall, which extends for part of the length of a side-face of the bolt head, and against which side-face has, planar support. The faces for contact on the circumferential wall are spaced apart from one another. There is formed in the circumferential wall of the receptacle, between each pair of adjacent faces for contact, a recess wherein there is no contact between the bolt head and the circumferential wall of the receptacle.

A system for fastening a rail to a tensioning clamp for a system, which rail has a rail foot, a web positioned thereon and a rail head, with a carrying plate and a tensioning clamp held on the carrying plate, which has a central portion for bracing the tensioning clamp on the carrying plate, at least one torsion portion branching off from the central portion in the lateral direction and a holding arm which is connected to the torsion portion via a curved transition portion, extends, starting from the transition portion, counter to the torsion portion and exerts via the free end of its end portion a resilient holding-down force on the rail foot of the rail to be fastened, the length of the torsion portion and the course of the transition portion being adapted to each other in such a way that at least the transition portion is guided without supports laterally past a region of the carrying plate that is associated with the central portion of the tensioning clamp. A tensioning clamp which is particularly suitable for this purpose is disclosed, wherein the end portion of the holding arm is angled away from the torsion portion in such a way that it points, in the direction of the web of the rail to be fastened.
