Abstract

The invention relates to a system for attaching a rail S to a substrate U, the system having a nut (7) which can be screwed onto the threaded segment (32) of the stud bolt (5) and which works on the central loop (14) of the tension clamp (3) to tension the tension clamp (3) against the substrate (U). Such a system according to the invention can be cost-effectively produced and easily assembled because the nut (7) has an extension on its underside (U) in the shape of an annular section (29) which abuts the inner sides of the side pieces (15, 16) of the central loop (14) in the space (17) laterally bordering the side pieces (15, 16) of the central loop (14) in a gripping and form-locking manner, and the nut has an inner threading (30) which fits to the threading of the stud bolt (5) threaded segment (32).

Description

SYSTEM OF CLAMPING A RAIL ON A BASE FIELD OF THE INVENTION The invention relates to a system for fastening a rail to a base, which is fastened to the base when the system is completely threaded and has a threaded part that projects freely from the base when the threaded pin is clamped to the base. base.

BACKGROUND OF THE INVENTION They use systems of this type, for example, to fasten a rail on concrete blocks or concrete sleepers. The bases of this unshakable type that are also called "block shoes", block shoes have been successfully tested in high speed and in the heavy transport traffic sector since the rail is especially precise and safe. The loading of the RIEL can be done in a comparably simple manner in such a way that and assemble. n Rail fastening system specially designed is simply the "RN system". It comprises a spring element designed from a leaf spring, having a spring part and a support part, that of an axis in a direction transverse to the longitudinal axis of the element d such that it rests on the base of the spring part. The part of the wheel is longer than the support part, so that it projects freely with a final part.

When it is fully assembled, the applicable end part rests or rests and remains on the firm base by means of an elastic resilient layer resiliently directed against the firm base. The pretension is necessary for this to be achieved here in which a threaded bolt is firm and is guided by through openings formed in the support portion d, and a nut is screwed onto the threaded bolt, acting as a washer on the side superior of the firm muell element. The spring element is supported simultaneously, with its part u being rándose There is also increased abrasive wear in the region of the positional groove, as a result of which the anti-spring seat itself is no longer secured even after a short period of time.

The rail fastening system of the type mentioned at the beginning is published by the applicant "Schienen-Befestigungs-Systeme für Beto 14". In this system, the rail to be fastened is also placed directly on the middle of a resilient intermediate layer. The rail is guided here later at an angle, which in each case form a channel for the rail at which the respective rail sits. The forces introduced by the guide plate at an angle into the base carrying the rail add a flange on the respective base for each of the plates on which the associated angle guide plate rests.

In the W14 system, a W-shaped tensioner, which presses its arms free on the upper free side of the rail shoe of the completely assembled rail, is assembled on the guide plate at an angle curved to the lacquer. in n They lie on the track shoe and the support parts of the tension clamp which is generally grooved and formed at said angle.

The advantage of the concept of the angle-based rail clamping system W14 and the comparable systems is the fact that the tensioning screw of the tension clamp can be kept substantially free of ales, thus ensuring a permanent secure support of the r and minimum risk of damage. break. However, the drawback is that it is used in the known system and requires an installation space with the RN system, and the tensioning screw requires a large length? Fasten the tension clamp with simple assembly. For the W1 function and similarly constructed systems, it is necessary that it be supported in each case on the firm base, by means of which the elements absorbed by the angled guide plate are guided towards each other.

A system according to the invention for fastening a rail on u with the prior art, comprises a threaded bolt attached to the bas is fully assembled. This threaded bolt has a part rosc freely on the upper side of the base when the threaded bolt A system according to the invention simultaneously comprises a piece, having a central loop and at least one arm or the central loop, the central loop having two side pieces that are spaced apart, which between them limit a space, in that the thread is arranged when the system is fully assembled and, when the system is fully assembled, with its final part li, exerts a resilient clamping force on the track shoe to be sublimated, the system in accordance with the The invention also comprises screwing on the threaded part of the threaded bolt and, when assembled, acts on the central loop of the tension clamp with the tensioner against the base. positive and positive between the nut and the threaded part of the bolt by the height of the flange with respect to the nut that, according to generally to reinforce a tension clamp, acts only optionally by means of a washer on the loop tensor. or on the other hand, it is secured by the conformation of the extempt flange according to the invention, said conformed being the sides of the central loop of the tensioning fastener which, the central loop and securely even under the large loads that are produced Because of this design according to the invention of the pre-nut according to the invention, it is therefore possible to fasten a fastener according to the design of conventional fasteners on a p roject only by a short piece comparatively on the side, on which the rail is to be fastened. As a result, a system requires little height in the fully assembled position.

This is supported positively on the flange. If, for example, the fastening of a circular cable material substantially in cross section, crosswise of the neck formed in the flange of the nut is circular in order to enable a simple assembly with onal devices which, especially, work automatically , the Turkish head must, on which the coupling faces of the bias are configured.

? The fact that the length of the side pieces of the central loop d the length of at least one spring arm of the tension clamp is such that, seen in plan, the central loop projects from the spring arm of the tension clamp, ensures that the central loop when it is fully assembled to project on the shoe of the central loop can be used as security against lifting the rail.

A reliable transmission of the clamping force to be applied by the track shoe braces can be achieved because the end part of the arm of the r "r" n l ir i Eral of the central loop of the tension clamp. In this case, the bra W, so that a uniform load of all components d is achieved.

A configuration of the fastening system according to the present invention is characterized in that, in accordance with the foregoing, it comprises an angled guiding pest that is arranged so that its upper side is free in the assembly position. , has to guide the tensioner bra. If a matching depression is present that the rail is to be fastened, the angled guide plate on its underside may have a projection which is arranged to engage to form a positive assurance of the position of the guide plate in assembly. The electrical isolation of the clamping system is made possible by the angled guide plate consisting of an insulating material. The fastening system according to the invention comprises an electrically insulating material elemroduce and has a receiver of the spring arm of the tension clamp and is designed to be relevant terminal the rail to its etar.
