Abstract
A device for attaching a rail to a bearing element (tie) (3) and comprising an elastic intermediate plate (34) and on top of this a rigid pressure distribution plate (35) which is arranged between the base (2) of the rail (1) and the tie (3); guide plates (10, 11) are attached to the tie (3) to provide lateral guidance of the base of the rail (2) and clamps (38) act on the base of the rail (2) and clamp the rail (1) to the tie (3). The elastic intermediate plate (34) projecting on both sides beneath the base (2) of the rail (1) extends on each side into a recess (16, 17) formed by the guide plate (10, 11). As a result, the elastic intermediate plate (34) can provide adequate resistance to the horizontal forces so that tilting of the rail is prevented. At the same time, the major forces of the clamps (38) are transmitted via the guide plates (10, 11) directly to the tie (3) so that non-uniform compression of the elastic intermediate plate (34) cannot occur during assembly and thus rail cant errors are avoided.
