Description

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

It is known that in vehicles, for example in rail vehicles, floor panels are used which have to be leveled out in order to compensate for tolerances during installation.

For example, the pamphlet describes EP 2 409 889 A1 a floor for a vehicle. Tolerance compensation on floor panels is made possible by using a clamp fixation for a floating bearing of the floor panels. The clamp is fixed using screws and sliding blocks that can be moved in longitudinal and transverse grooves. Due to the floating mounting, tolerance compensation in a longitudinal and transverse direction of the vehicle is 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 JP 5 858624 B2 shows a rail vehicle, wherein a space between a floor panel and a passenger cabin floor is secured. Sides of the passenger cabin floor are supported by an outer floor bracket and a side beam so as to extend in the longitudinal direction of a side groove body.

The invention is therefore based on the object of creating a floor structure, a method for installing a floor structure and a rail vehicle with the floor structure, in which tolerance compensation of a floor panel in a vertical direction is possible with simple means, with the installation of the floor structure being simplified .

According to the invention, this object is achieved with a floor construction according to claim 1 . Furthermore, the object is achieved with a method for installing the floor structure according to claim 8 and a rail vehicle according to claim 14. Advantageous developments of the invention are contained in the dependent claims.

According to the invention, the solution to the problem is a floor structure with the technical features of claim 1.

One advantage of the invention is that tolerance compensation in a vertical direction is made possible by means of the compensation device. The compensating device has only two arms arranged at right angles to one another. The arms are straight, ie they are free of curves and bends and are not bent. Also, as used herein, the term "straight line" is understood to mean that the arms follow a course of a straight line, the arms also having a predetermined material thickness. The arms can be integrally connected to each other. Thus, the compensating device has a very simple structure. Due to the compensating device, it is possible to use the base plate with the Pre-assemble floor bearing element, whereby the assembly of the floor structure is simplified overall.

A first arm of the balancer may abut and be attached to a side wall. This allows the compensating device to be easily installed on the side wall.

The base plate is preferably fastened to a second arm of the balancing device, in particular by means of an adhesive. The base plate thus rests on the second arm of the compensating 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 insulating means and/or the drainage insulation can be pre-assembled below the base plate. This simplifies the assembly of the floor structure. Due to the simple construction of the compensation device, an insulating means and/or a drainage insulation can also be arranged below the compensation device. The insulating medium can dampen vibrations and the drainage insulation can wick away moisture.

In a particular development of the invention, a transition profile is arranged between at least one end of the base plate 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 deflection of the floor covering.

In particular, the transition profile is arcuate. An arcuate version of the transition profile is easy to manufacture and forms a rounded shape at a corner between the floor panel and the profile element. Alternatively, the transition profile can have a right angle or an obtuse angle instead of the arcuate design.

In addition, the transition profile can adjoin a profile element, e.g. The transition profile forms a transition between the base plate and a vertical profile element, e.g. an air duct, arranged parallel to the side wall. At least one gap between the base plate and the profile element is thus bridged in order to prevent dirt or the like from penetrating. The seal covers a gap between the transition profile and the profile element.

1. a) Befestigung zumindest des Bodenlagerelements und des Übergangsprofils an der Bodenplatte, wobei zumindest die Bodenplatte, das Bodenlagerelement und das Übergangsprofil eine vormontierte Einheit bilden,
2. b) Einstellen der Ausgleichseinrichtung in der senkrechten Richtung und Befestigen der Ausgleichseinrichtung an der Seitenwand,
3. c) Aufsetzen der vormontierten Einheit auf den Unterboden und auf die Ausgleichseinrichtung
4. d) Befestigen der vormontierten Einheit an der Ausgleichseinrichtung.

Furthermore, the solution to the problem consists in a method for installing the floor structure, the method comprising the steps:

1. a) Fastening at least the floor bearing element and the transition profile to the floor panel, with at least the floor panel, the floor bearing element and the transition profile forming a preassembled unit,
2. b) adjusting the balancer in the vertical direction and fixing the balancer to the side wall,
3. c) Placing the pre-assembled unit on the underbody and on the compensation device
4. d) Attaching the pre-assembled unit to the compensating device.

An advantage of the method according to the invention is that a tolerance compensation of a floor panel takes place in a vertical direction by means of the compensation device. The assembly of the floor structure is also simplified overall. The transition profile is also pre-assembled.

In addition, in step a), the floor covering can be attached to the floor panel and to the transition profile. So the floor covering can also be pre-assembled.

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

In a further embodiment of the invention, at least one second drainage insulation is attached to the subfloor between step b) and step c). Due to the geometry of the compensating device and its attachment directly to the side wall, there is enough space for a second drainage insulation.

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

In addition, the task is solved by a rail vehicle with at least one floor structure.

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 as an example in relation to a rail vehicle. The rail vehicle has an underbody 20 and a side wall 21 and is otherwise not shown in any more detail. The floor structure 10 is shown in the figure only in the area of a side wall 21 . However, the floor structure 10 is constructed accordingly in the area of a further side wall opposite the side wall 21 . The floor structure 10 is thus built into the rail vehicle symmetrically in a transverse direction y. A longitudinal direction x of the rail vehicle corresponds to a direction of travel.

In the area of the side wall 21 , the floor structure 10 has a floor bearing element 30 which is arranged on the subfloor 20 . A base plate 31 rests on the base bearing element 30 . Between the underbody 20 and the floor panel 31 are a first insulation means 40 and a first drainage insulation 41 are arranged. The first insulating means 40 is arranged between the floor panel 31 and the first drainage insulation 41 which rests on the subfloor 20 .

A floor covering 50 rests on the floor panel 31 . One end 51 of the floor covering 50 is deflected at one end 32 of the floor panel 31 . In this case, 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 borders on a seal 53 . The seal 53 seals the floor covering 50 against a profile element 60, for example a channel element.

In addition, the floor structure 10 has a compensating device 70 in the area of the side wall 21 . The compensating device 70 is here an angle 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 attached to the side wall 21 by means of an attachment unit 73, for example a screw connection. The compensating device 70 can be displaced together with the fastening unit 73 in a vertical direction z, for example in a slot 22 in the side wall 21. The end 32 of the base plate 31 rests on the second arm 72. The bottom plate 31 may be attached to the second arm 72 by means of an adhesive 74, for example. A second insulating means 80 and a second drainage insulation 81 are arranged between the equalizing device 70 and the underbody 20 . The second insulating means 80 is arranged between the equalizing 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 insulating 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 floor panel 31 . The seal 53 can be preassembled on the transition profile 52 . Overall, a large part of the floor structure 10 can be built into the rail vehicle as a preassembled unit, with the preassembled unit being held together by at least one adhesive.

Before installing the preassembled unit in the rail vehicle, however, the compensating device 70 must be adjusted in the vertical direction z. A corresponding further compensating device must also be set in the vertical direction z on the further side wall opposite the side wall 21 . With the help of the compensating device 70 and the additional compensating device, tolerances are compensated for or leveled out during the installation of the preassembled unit. The base plate 31 then assumes a horizontal position, with a predetermined tolerance range being maintained. When the compensating device 70 and the further compensating device are adjusted, 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 insulating means 40 and the second insulating means 80 can have mineral wool, for example. The bottom plate 31 can be made of birch plywood, for example.

The height of the floor structure 10 can vary in different rail vehicles and can be adapted to different installation conditions. A weight of the preassembled unit can be controlled by setting the size of the bottom panel 31 . Installing the preassembled unit shortens assembly times for the floor construction in final assembly, ie when assembled in the rail vehicle.
