Embodiment Construction
[0092] A system 1 for fixing a track S on a fixed base U formed, for example, of cement sleepers or cement slabs, the system comprising a first backing plate 2, a second backing plate 3, an elastic intermediate layer 4, a pressure distribution plate 5, a height Adjustment plate 6, first guide plate 7, second guide plate 8, two elastic parts 9, 10 formed as ω-shaped clamping clips, two pairs of adapters 11-14 and two clamps formed as clamping bolts Clamping elements 15 , 16 act on the central rings of the spring elements 9 , 10 via washers 17 , 18 .
[0093] The fastening system 1 is seated in a receptacle 19 formed in one piece on the fastening base, which is delimited on its narrow side extending parallel to the rail S by support shoulders 20 , 21 . In the bearing surface of the receptacle 19 present between the support shoulders 20 , 21 , plastic pins 22 , 23 are respectively inserted into the base U adjacent to the support shoulders 20 , 21 . When assembling the system 1 ,...

Abstract
The invention relates to a system (1) for fastening a rail S on a subsurface (U) and a spacer (2, 3) intended for such a system (1). The system (1) comprises a guide plate (7, 8) for laterally guiding the rail S to be fastened, a spring element (9, 10), which can be braced against the subsurface (U) by means of a tensioning element (15, 16) and which sits on the guide plate (7, 8) and with a free spring arm (48, 49) exerts a hold-down force on a rail foot (F) of the rail (S) when the system (1) is completely assembled, and a spacer (2, 3), which is arranged to equalize the height differences between the guide plate (7, 8) and the respective subsurface (U). The spacer (2, 3) is to be divided in two parts (24, 25) along a joint line (32), which is guided, starting from one of the longitudinal sides (26, 27) of the spacer (2, 3) that are aligned transversely to the rail to be fastened (S), at a distance (a1, a2) to one narrow side (28, 29) of the spacer to the through-passage (30, 31), and from there is guided in the direction of the narrow side (28, 29) of the spacer (U), intersecting the through-passage (30, 31).
Description
technical field [0001] The invention relates to a system for fixing a rail on a base, which system has a guide plate guiding the rail to be fixed on its longitudinal side, an elastic part which can be clamped with respect to the base by means of a clamping element, the elastic part sits on the guide plate and in the fully assembled system exerts a pressing force with a free spring arm on the rail foot of the rail to be fixed, and also has a backing plate which extends transversely to the rail to be fixed through the width of the guide plate, the A backing plate is provided to equalize the height difference between the guide plate and the individual bases, wherein the backing plate has a rectangular basic shape and has through-openings for the clamping elements used for clamping the elastic elements. [0002] The invention also relates to a mounting plate for such a system, which is used on the one hand to support the other components of the fastening system over a large area o...
