Problems solved by technology

The disadvantage, however, is that the stress clips used in the known system require a larger installation space compared to the RN system, and that the clamping screws require a greater length in order to be able to compress the stress clips in a simple installation process

Embodiment Construction

[0074] The fastening system B for fastening the track S to a fixed foundation U made of cement consists of two systems 1 , 2 .

[0075] Each system 1 , 2 for fixing the rail S comprises stress clips 3 , angle guide plates 4 , bolts 5 , insulating means 6 and nuts 7 screwed on the bolts 5 .

[0076] The angle guide plates 4 are made of a non-conductive plastic material and each have a through-hole for a screw 5 . On its underside corresponding to the foundation U, the angle guide plate 4 has a projection 8 which is parallel to a bearing surface 10 of the angle guide plate 4 which bears against the rail base 9 and thus the The lugs run parallel to the track S. As shown in FIG. The structure of the projection 8 is adapted to the structure of the groove 11 formed in the top side 12 of the fastening base U corresponding to the angle guide plate 4 . In this way, the projection 8 of the angle guide plate 4 engages positively in the groove 11 in order to ensure that a rotation of th...

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

technical field [0001] The invention relates to a system for fixing rails to a foundation, the system having a bolt fixed in the foundation in the completed installed system, the bolt having a threaded section, at the bolt fixed in the foundation, the thread The sections protrude from the top side of the foundation with a vacancy. Background technique [0002] Systems of this type are used, for example, to fasten rails in foundations consisting of cement slabs or concrete sleepers. Such foundations made of non-flexible materials are also known as "fixed pavement". [0003] Fixed pavement is possible in the areas of high-speed passenger transport or heavy freight transport because it enables particularly precise and secure track fixing. At the same time, the track load can be adjusted in a relatively simple manner to achieve the desired service life. Thus, for example, by arranging an elastic intermediate layer between the rail and the respective foundation, a certain amou...
