Rail attachment system for junction areas

摘要

The invention relates to a rail attachment system (1) for attaching a rail (2) to a concrete support slab (3a) or a concrete sleeper (3b) or to a steel structure comprising an intermediate plate (4), a rail attachment plate (5) with angle guide plates (6, 6b) arranged thereon, at least two first tensioning clamps (7a) for clamping the rail foot (2a) to the rail attachment plate (5) as well as screws (9) and/or ankle bolts (10) and at least two second tensioning clamps for screwing the rail attachment system (1) to the underlying surface, characterized in that an elastic intermediate layer (8) is arranged between the rail (2) and the rail attachment plate (5), and the intermediate plate (4) is composed of a highly elastic material and/or comprises a steel plate (4), at least two second tensioning clamps (7b) for clamping the rail attachment plate (5) to the substructure, preferably via the intermediate plate (4), wherein the first and second tensioning clamps (7a, 7b) are embodied in a highly elastic fashion with a high tensioning force, are provided, and at least one upper sliding plate (12) is arranged between the rail foot (2a) and a first tensioning clamp (7a), and at least one lower sliding plate (13) is arranged between the rail foot (2a) and the elastic intermediate layer (8) and is attached by means of a steel support (14) in the case of a steel substructure.

主权项

1. A track-fastening assembly for attaching a rail to a substrate formed by a concrete support slab, a concrete sleeper, or a steel underlayment, the assembly comprising:
an intermediate plate formed of highly elastic material or steel; a rail-attachment plate provided with angle guides; at least two first spring clips for clamping a rail foot to the rail-attachment plate; first and second anchors formed by screws or bolts, the first anchors being seated in the rail-attachment plate and holding down the first spring clips; an elastic intermediate layer between the rail and the rail-attachment plate; at least two second spring clips attached by the second anchors to the substrate and clamping the rail-attachment plate to the substrate via the intermediate plate, the first and second spring clips being highly elastic and exerting a high tension force; at least one upper slide plate between the rail foot and a first spring clip; and at least one lower slide plate between the rail foot and the elastic intermediate layer.
