Abstract

The invention aims to improve a floor for rail vehicles in such a way that an even, level, reference plane for constructing the floor is obtained by a simple tolerance compensation of the deviations in the longitudinal direction, transverse direction and height of the shell assembly. Said compensation is embodied as an easy-to-assemble positive-fit connection between the floor plate and the body-shell floor plate. This is achieved by a retaining profile which is configured as a profile with a recess for accommodating a connecting element and provided with at least one blind opening. An elastic spacer, comprising a plug-in extension to compensate for the existing differences in level between the floor plate and the floor-profile plate, is inserted into the blind opening under pressure, forming a positive-fit. The positive-fit between the blind opening and the plug-in extension is perpendicular in relation to the positive-fit between the profile batten and the retaining profile.

Dependent claims

Floor for vehicles, in particular railway vehicles for transporting passengers, with a rigid bottom profile plate on which profile battens (4) that are elastic in the longitudinal direction and have recesses (5) are clamped as an isolation profile in projecting retaining webs (3) so that they can move in the longitudinal direction, whereby a rigid retaining profile (6) is fixed in the recesses so that it can move longitudinally, and with floor plates that are laid in the transverse direction with respect to the longitudinal direction of the vehicle, whereby the transverse edges of the floor plates are connected to one another,

characterized by the fact
that the retaining profile (6) is realized in the form of a profile in which there is a recess (13) to receive a connecting element (14) and at least one blind hole (7), in which an elastic spacer (8) is engaged by means of a plug-in extension (10) to equalize any differences in level between the floor plate and the bottom profile plate in a positive-fitting manner, whereby the positive fit between the blind hole (7) and the plug-in extension (10) is oriented perpendicular to the positive-fit connection between the profile batten (4) and the retaining profile (6).
