Embodiment Construction

[0042] A system 1 for fastening a track 2 on a rigid foundation 3 formed, for example, of a concrete slab or a concrete sleeper, which system 1 comprises an elastic intermediate plate (here not show).

[0043] Arranged on the intermediate plate is a base plate (also not shown here) made of steel, which covers the intermediate plate and which in actual use produces The load (along the direction of gravity) acting on the base plate through the track 2 is distributed on the middle plate.

[0044] Another intermediate layer (also not shown here) covers the substrate. The width of the intermediate layer corresponds at most to the width of the bottom 4 of the rail 2 , the lower surface of which is arranged on the intermediate layer.

[0045] In order to adjust any desired inclination formed by the rail 2 with respect to the horizontal surface of the rigid base 3, the base plate may have a wedge-shaped cross-section, the upper surface of the base plate associated with the rail bott...

Abstract

The invention relates to a support for a system (1) for fastening a rail (2) on an underlying surface (3), comprising a support angle (14) having a base section (23) with a contact surface (23a) associated with the respective underlying surface (3), a supporting section (22) placed on the base section (23), said supporting section having a contact surface (21) on its free front side where the rail (2) is to be fastened, and a passage opening (29) formed into the base section (23) for passing through a fastening element (17, 19) used for the fixation of the support angle (14) on the underlying surface (3). According to the invention, the passage opening (29) comprises in at least one direction parallel to the contact surface (23a) an overdimension in relation to the circumference of the part (19) of the fastening element (17, 18), which, in the mounted state, is placed in the passage opening. Furthermore, an additional stop piece (15, 16) that cooperates with the fastening element (19) is provided for fixing the support angle (14) in a respective relative position of the fastening element (17, 18) and the support angle, obtained by a relative displacement.

Description

technical field [0001] The invention relates to a support for a system for fastening a rail to a base, the support comprising an angle bracket having a base with a contact surface associated with a corresponding base, a support portion standing on the base , having a bearing surface on the free front side of the support part associated with the rail to be fastened; and a through-hole formed in the bottom into which fastening means for fastening the angle bracket to the base are inserted . [0002] Furthermore, the invention relates to a system for fastening a rail to a base, comprising: a guide plate for laterally supporting the rail to be fastened; an elastic element supported on the guide plate and having at least one elastic arm , the elastic arm is arranged to exert an elastic retention force on the bottom of the track; means for fastening the elastic element; Lateral forces generated during upward travel support the guide plate. Background technique [0003] A suppor...
