Embodiment Construction

[0092] The system 1 for fastening the rail S on a fixed base, not shown in detail here, made of concrete sleepers, comprises: a base plate 3 made of plastic; a correspondingly arranged intermediate layer below the base plate 3 4. The middle layer is made of elastic material; under the middle layer 4, the support plate 5 is set on the fixed base 2; four eccentric bushes 6a, 6b, 6c, 6d are respectively set corresponding to each eccentric bushing. There are fixing bolts 7a, 7b, 7c, 7d serving as fixing parts; two spring parts 8a, 8b; two adapter parts 9a, 9b; and two clamping bolts 10a, 10b.

[0093] Seen from above, the backing plate 3 made of plastic has a bone-shaped extensive structure. In this case, the width B of the backing plate, which is determined along the longitudinal extension L of the rail S to be fastened, in each outer region 3a, 3b delimiting its narrow sides, is significantly greater than the width of the backing plate in the middle region, wherein the width B s...

Abstract

The invention relates to a support plate and a securing element comprising said type of support plate, having a minimum weight and optimum rigidity and which is also suitable for supporting an elastic intermediate layer. According to the invention, said claimed support plate for securing a rail (S) to a solid foundation (2) is made of a plastic material and has a reinforced structure (3s) which is formed on the underside (U) of said support plate (3) associated with the solid foundation (2), said reinforced structure being formed from ribs (3t) and recesses (3u) which are arranged therebetween. The claimed recesses of the reinforced structure (3s) are closed by a filling material (T).

Description

technical field [0001] The invention relates to a backing plate for fixing a rail on a fixed base, wherein the backing plate is made of plastic and a reinforcing structure is formed in the underside of the backing plate corresponding to the fixed base, the reinforcing structure consisting of It is composed of ribs and recesses located between the ribs. [0002] In addition, the present invention also relates to a fixing device for a rail made of the above-mentioned backing plate. Background technique [0003] In practice, a track fixing system is known for short "ECF", in which the track rests on the contact surface of a backing plate made of steel. On the long side of the backing plate which is oriented in the longitudinal direction of the rail to be fastened, the contact surfaces are each delimited by a rib, on which the rail support is guided laterally in the assembled state. In addition, the rib serves as a support for the clamping bolt, which is inserted with its scre...
