EP1198376B1 - Floor for vehicles, in particular, rail vehicles for transporting passengers - Google Patents

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.

Description

The invention relates to a floor for vehicles, in particular Rail vehicles for the transportation of people, with a rigid floor profile plate, on the longitudinally elastic profile strips with recesses as a decoupling profile in holding bars are held clamped longitudinally displaceable, being in the recesses fixed a rigid support profile longitudinally and with floor panels that are transverse to the vehicle's longitudinal direction are arranged laid, the transverse edges of the Floor panels are interconnected.

EP 0 622 286 B1 describes a sound-absorbing support element for Covering bodies, in particular for the formation of floors in railway vehicles known for passenger transportation, which from a on Support body or rigid profile attached to the cover body, that against the respective other body with interposition an insulating element is supported elastically. On the carrier or cover body is attached an elastic profile strip, which has a recess in which one to the other Body open, rigid hollow profile defined by a clamp fit is by attaching the rigid hollow profile into the recess grip the elastic profile strip. A second rigid profile is attached to the ceiling or support body, which has a web, which engages in the open hollow profile and by means of a elastic insulation material at a distance with the rigid hollow profile is elastically connected, the insulation material having physical properties has such that it is suitable for higher frequencies sufficient to insulate. Between the rigid profile and the ceiling or support body is a compensation layer made of elastic Material, for example made of rubber, arranged.

The profile bar of this known support element is longitudinally displaceable arranged, a height tolerance compensation for leveling however, the floor plate is on a horizontal surface only by inserting the compensation insert made of elastic Possible material. Due to the occurrence in the floor area of the shell Construction deviations are the height tolerances of the support point to the point of support of the floor slab, so that an individual compensation is only possible if the Montage these deviations are found and the compensatory supplement is dimensioned accordingly. It arises high expenditure of time. In addition, the known support element is through the use of two rigid ones connected by a PUR soft foam Profiles labor-intensive, but at the same time relatively difficult and requires quite a height, which is the longitudinal movement through the recesses in the profile strip conditional leverage of force application impaired.

DE 44 41 290 C1 describes a vibration and sound absorbing, elastic supporting connection element for floors of rail vehicles for the transportation of passengers, in particular for a double-shell, wood-free floor in segment construction, being between the floor panel and the body frame section-wise elastic absorbing Intermediate links arranged across the body of the car body are. The elastic connecting element consists of a through the side wall profiles lying across the body of the car body limiting the body of the car in its longitudinal extent Profile body with a positive on top of this applied elastic pad on the one hand and on the other from a section below in the same direction, on the car body underframe elastic adhesive application. As a support for floor attachments such as seat frames, handrails, partitions and climate protection walls plate-shaped webs are embedded in the profile body.

In the longitudinal direction of the car body underframe, elastic spacer strips are arranged to the left and right of the elastic adhesive application, which both create the distance between the profile body and the car body underframe required for bonding and also form a leveled level for the subsequent floor construction.
In this known solution, too, there is between the floor plate and the profile body resting on the spacer strip an elastic rubber pad with elevations and depressions pointing towards the floor plate, which must be dimensioned differently in order to compensate for height tolerance deviations.
With this solution, the disadvantages mentioned at the beginning cannot therefore be eliminated. In addition, this known prior art has the disadvantage that the supports must be positioned very precisely in the transverse direction. The use of adhesive is also complex and expensive.

Furthermore, EP 0 576 394 A1 discloses a vibration and sound-absorbing elastic connecting element for the floating mounting of a floor structure on a supporting vehicle floor of rail or road vehicles for the transport of people with an elastic body with contact surfaces for the vehicle floor and floor structure. The connecting element has a basic profile with a support surface for the car floor and a cover profile which is offset in height from the basic profile with a support surface for the floor structure, each with opposing, essentially perpendicular to the car floor and floor structure, and an elastic surface arranged between the stop surfaces and adhering to them Mass on.
This known vibration and noise-damping connecting element also permits an individual height compensation of tolerance deviations only with a correspondingly high expenditure of time and installation.

In this prior art, the invention is based on the object to improve a floor for rail vehicles in such a way that a level, sales-free reference level for the floor construction through a simple, easy-to-assemble tolerance compensation the deviations in the bodywork in the longitudinal and transverse directions and in height as a pure positive connection between the floor slab and car body base plate is made possible.

This task is done by a floor of the type mentioned Kind solved with the characterizing features of claim 1. Advantageous refinements can be found in the subclaims.

The height compensation in the tolerance deviations is carried out by Insert elastic spacers with the height deviation adapted dimensions in the holding profile, so that easily A level reference plane is created for the floor structure Assembly is simple and time-saving at the same time. The invention Floor construction is also characterized in that its height and weight is low and still excellent Damping and vibration behavior due to the different Shore hardness of profile strip and spacer reached becomes.

The advantages achieved with the invention therefore exist in that the assembly times can be shortened Manufacturing costs reduced and individual height compensation the tolerance deviations over the body length and width becomes possible. The floor plate made of wood or aluminum can thereby free of sales and consistently on the one reference level leveled supports' while maintaining the Longitudinal displaceability can be placed or fastened.

An embodiment of the invention is based on the Illustrated drawings.

In Fig. 1 the basic structure of the floor is shown. A floor profile plate 2 composed of multi-chamber profiles rests on the longitudinal beams 1 of the car body. In the longitudinal direction, the floor profile plate 2 has upstanding retaining webs 3, in each of which elastic profile strips 4 of short length, for example with a length of 200 mm, are held in a positive manner in the longitudinal direction. The profile strips 4 are made of rubber and are designed such that two recesses 5 in the rubber body opposite each other are formed in each case for the reception of a rigid holding profile 6 .
The holding profile 6 consists of metal, preferably of aluminum, is profiled flat and in turn has two contact surfaces F, which are spaced apart by a recess 13 . The recess 13 is countersunk in the center of the holding profile 6 and preferably accommodates a blind rivet nut 16 for the subsequent screwing of the floor panels 12 . For this purpose, transverse oblong holes 17 are provided in the floor panels 12 .

Blind holes 7 are machined in the holding profile 6 and extend vertically to the bearing surfaces F. The holding profile 6 is inserted into the recesses 5 and is positively held so that it is able to move in the longitudinal direction. In the inserted state, the contact surfaces F close the holding section 6 is about the height _H B of the profile strip 4, so that the retaining profile, the overall height _H B of the profile strip does not exceed 6. 4 By replacing the holding profile 6 , the floor height can be set higher or lower while maintaining the rest of the structure.
Spacers 8 made of rubber are inserted into the blind bores 7 of the holding profile 6 in a form-fitting manner. For this purpose, the spacer 8 has a plug-in extension 10, the diameter of which is coordinated with the diameter of the blind bore 7 and ensures a secure fit in the blind bore 7 . As it were, T-shaped, the plug-in extension 10 merges into a crosshead 9 , which is adapted to the contact surface F accordingly.

2 shows a section of a floor profile plate of a car body shown in plan view. The holding webs 3 of the floor profile plate 2 are spaced apart from one another such that they form an alignment A with one another in the longitudinal direction. As already mentioned, the webs 3 hold the profiled strip 4 made of rubber, which in turn holds the holding profile 6 in a longitudinally movable manner, the holding profile 6 with the spacers 9 . Crosspieces 3, profile strip 4, holding profile 6 and spacers 8 together form supports 11. The floor 12 subsequently constructed is supported on these supports 11 .
Due to the body-in-white tolerances in the floor area of the car body production, the individual supports 11 have a different height level H _N in both the longitudinal and transverse directions .
In order to level this different height level H _N for the floor to be built up, as shown in FIG. 3, the spacers 8 have crossheads 9 with different thicknesses (thicknesses) which compensate for the tolerances. For this purpose, starting from a fixed point FP (see FIG. 1), which is expedient at a

The longitudinal beam 1 is fixed, the height level H _{N is determined} for each support 11 in the longitudinal and transverse directions. The spacers 8 with the correspondingly determined strengths
in the crossheads 9 with their plug-in extensions 10 are inserted into the blind holes 7 of the holding profile 6 . A leveled reference level for the floor structure is created. This is the crucial prerequisite for a consistently flat floor as a basis for the entire interior of the passenger compartments.

The number of supports 11 to be set up depends on the load or deflection of the floor profile plate and the floor 12.

The rubber of the profile strip 4 and the rubber of the spacers 8 have a different shore hardness. This ensures a particularly good decoupling between the components in terms of sound and vibration damping.

Fig. 4 shows in section two floor panels 12, for example made of wood, which are connected and stiffened to one another along the transverse transverse joints by a T-profile 15 made of aluminum. The T-profile 15 is inserted between the abutting floor panel ends so that a bottom of the floor panels 12 comes to rest on the inside of the crosshead 18 . The inner web height SH of the T-profile 15 corresponds to the thickness of the floor plate 12 and thereby forms a continuous, flat connection of the floor plates to one another and stiffens them. The T-profile 15 is preassembled on a panel edge QK of the floor panel 12 and placed on the supports 11 . The other floor plate 12 is placed on the other part of the crosshead 18 and fastened to it by a connecting means 19, for example screws.
