Description

Floor structure for a vehicle, method for assembling a floor structure and rail vehicle with at least one floor structure

description

The invention relates to a floor structure for a vehicle, a method for assembling a floor structure and a rail vehicle with at least one floor structure.

It is known that in vehicles, e.g. used in rail vehicles, floor panels that have to be leveled to compensate for tolerances during installation.

For example, the document EP 2 409 889 A1 describes a floor for a vehicle. Tolerance compensation on floor panels is made possible by using a clamping fixture for floating storage of the floor panels. The clamp is fixed by means of screws and sliding blocks that can be moved in longitudinal and transverse grooves. Due to the floating bearing, a tolerance compensation in a longitudinal and transverse direction of the

Vehicle possible. The disadvantage here is that tolerance compensation is only possible in the longitudinal and transverse directions. In addition, complex hollow profiles with grooves are required.

The invention is therefore based on the object of providing a floor structure, a method for assembling a floor structure and a rail vehicle with the floor structure, in which tolerance compensation of a floor plate in a vertical direction is possible with simple means, the assembly of the floor structure being simplified ,

This object is achieved with a floor structure according to claim 1. Furthermore, the object is achieved with a method for assembling the floor structure according to claim 8 and a rail vehicle according to claim 15. Advantageous embodiments of the invention are contained in the subclaims. According to the invention, the object is achieved in a floor structure for a vehicle, the vehicle having at least one underbody and at least two to one another

has opposite side walls, the floor structure has at least one floor slab and at least one floor covering which rests on the floor slab, the floor slab being fastened to at least one floor storage element, characterized in that at least the floor slab forms a preassembled unit with the floor storage element and the preassembled unit the underbody and at least one compensating device for compensating for tolerances, which is fastened to at least one side wall, the compensating device being adjustable in a vertical direction and having only two arms arranged at right angles to one another, which are provided exclusively for compensating tolerances.

An advantage of the invention is that by means of the compensation device

Tolerance compensation in a vertical direction is made possible. The compensation device has only two arms arranged at right angles to one another. The arms are rectilinear, ie free of curvature and bending as well as non-angled. In addition, the term “rectilinear” is to be understood here in such a way that the arms follow a straight line, the arms also having a predetermined material thickness. The arms can be connected to one another in one piece. The compensating device thus has a very simple structure Compensating device, it is possible to use the bottom plate Pre-assemble the floor support element, which simplifies the assembly of the floor structure overall.

A first arm of the compensating device can rest against and be fastened to a side wall. This enables simple mounting of the compensation device on the side wall.

The base plate is preferably fastened to a second arm of the compensation device, in particular by means of an adhesive. The base plate therefore rests on the second arm of the compensation device and is attached to it at the same time. This also enables easy assembly.

In a special embodiment of the invention, at least one insulation means and / or at least one drainage insulation is arranged below the base plate and / or below the compensation device. The insulation agent and / or the

Drainage insulation can be pre-assembled below the floor slab. This simplifies the assembly of the floor structure. The simple structure of the

Compensating device can also be below the compensating device

Insulation means and / or drainage insulation can be arranged. The insulation can dampen vibrations and the drainage insulation can wick away moisture.

In a special development of the invention, a transition profile is arranged between at least one end of the floor slab and at least one end of the floor covering, which deflects the floor covering from a transverse direction into a vertical direction.

This enables a seamless redirection of the floor covering.

In particular, the transition profile is arcuate. An arched version of the

Transition profile is easy to manufacture and forms a rounded shape at a corner between the base plate and the profile element. Alternatively, the transition profile can have a right angle or an obtuse angle instead of the curved design. In addition, the transition profile in the vertical direction can adjoin a profile element, for example a channel element, a seal being arranged in particular between the transition profile and the profile element. The transition profile forms a transition between the base plate and a vertical profile element, for example an air duct, arranged parallel to the side wall. Thus, there will be at least one gap between the

Bridged base plate and the profile element to prevent the ingress of dirt or the like. The seal covers a gap between the transition profile and the profile element.

Furthermore, the problem is solved in a method for assembling the

Floor structure, the method comprising the steps of: a) fastening at least the floor support element and the transition profile to the

Bottom plate, at least the bottom plate, the bottom bearing element and the

Transition profile form a pre-assembled unit, b) adjusting the compensation device in the vertical direction and attaching the

Compensation device on the side wall, c) placing the pre-assembled unit on the underbody and on the

Compensation device d) Attach the pre-assembled unit to the compensation device.

An advantage of the method according to the invention is that tolerance compensation of a base plate takes place in a vertical direction by means of the compensation device. The assembly of the floor structure is also simplified overall. That too

Transition profile is pre-assembled.

In addition, in step a) the floor covering on the floor plate and on the

Transition profile to be attached. So the floor covering can also be pre-assembled.

In step a), at least one first insulation means is preferably attached to the base plate. This increases the number of pre-assembled components of the floor structure. In particular, at least a first drainage insulation is attached to the first insulation means in step a). As a result, the number of pre-assembled components of the

Floor structure further increased.

In a further embodiment of the invention, at least one second drainage insulation is attached to the sub-floor between step b) and step c). Due to the

There is enough space for a second drainage insulation in the geometry of the compensation device and its attachment directly to the side wall.

Furthermore, at least one second insulation means can be attached to the second drainage insulation. There is also enough space below the compensation device for the second insulation medium.

In addition, the task is carried out by a rail vehicle with at least one

Floor structure solved.

An exemplary embodiment of the invention is explained in more detail below with reference to a single figure.

The figure shows a schematic sectional view of a floor structure according to the invention.

In the figure, a floor structure 10 according to the invention is shown by way of example with reference to a rail vehicle. The rail vehicle has an underbody 20 and a side wall 21 and is not otherwise shown. The floor structure 10 is shown in the figure only in the region of a side wall 21. However, the floor structure 10 is constructed accordingly in the region of a further side wall opposite the side wall 21. The floor structure 10 is thus symmetrical in a transverse direction y

Rail vehicle installed. A longitudinal direction x of the rail vehicle corresponds to a direction of travel.

The floor structure 10 has a floor bearing element 30 in the region of the side wall 21, which is arranged on the subfloor 20. A bottom plate 31 lies on the

Floor bearing element 30. Between the underbody 20 and the bottom plate 31 are a first insulation means 40 and a first drainage insulation 41 are arranged. The first

Insulation means 40 is arranged between the base plate 31 and the first drainage insulation 41, which rests on the sub-floor 20.

A floor covering 50 lies on the base plate 31. One end 51 of the floor covering 50 is deflected at one end 32 of the floor slab 31. The floor covering 50 is guided on a transition profile 52. The transition profile 52 is attached to the end 32 of the base plate 31. The transition profile 52 is adjacent to a seal 53. The seal 53 seals the floor covering 50 against a profile element 60, for example a duct element.

In addition, the floor structure 10 in the region of the side wall 21

Compensating device 70 on. The compensation device 70 here is an angular element with a first arm 71 and a second arm 72, the first arm 71 and the second arm 72 forming a right angle. The first arm 71 is fastened to the side wall 21 by means of a fastening unit 73, for example a screw connection. The

Compensating device 70 can be moved together with the fastening unit 73 in a vertical direction z, e.g. in an elongated hole 22 in the side wall 21. The end 32 of the base plate 31 rests on the second arm 72. The bottom plate 31 can e.g. be attached to the second arm 72 by means of an adhesive 74. A second insulation means 80 and a second drainage insulation 81 are arranged between the compensation device 70 and the underbody 20. The second insulation means 80 is arranged between the compensation device 70 and the second drainage insulation 81, which rests on the underbody 20.

During assembly, at least the base plate 31, the base bearing element 30 and the transition profile 52 are preassembled. The first insulation means 40 can also be preassembled on the base plate 31.

The first drainage insulation 41 can be preassembled on the first insulation means 40. The floor covering 50 can also be preassembled on the base plate 31. The seal 53 can be preassembled on the transition profile 52. Overall, a large part of the floor structure 10 can therefore be installed as a pre-assembled unit in the rail vehicle, the pre-assembled unit being held together by at least one adhesive. Before installing the preassembled unit in the rail vehicle, however, the compensation device 70 must be set in the vertical direction z. A corresponding additional compensation device must also be set on the further side wall opposite the side wall 21 in the vertical direction z. With the help of

Compensating device 70 and the further compensating device tolerances are compensated or leveled when installing the preassembled unit. The base plate 31 then assumes a horizontal position, a predetermined tolerance range being maintained. When the compensation device 70 and the further compensation device are set, the second insulation means 80 and the second drainage insulation 81 can be installed, specifically on the side wall 21 and the further side wall opposite the side wall 21.

The first insulation means 40 and the second insulation means 80 can, for example

Have mineral wool. The bottom plate 31 can e.g. be made of birch plywood.

The height of the floor structure 10 can be different in different rail vehicles and can be adapted to different installation conditions. A weight of

pre-assembled unit can be controlled by determining the size of the base plate 31. Installation of the pre-assembled unit shortens assembly times for the

Floor construction in a final assembly, that is, in an assembly in the rail vehicle.
