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, describes the publication EP 2 409 889 A1 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. The floating bearing enables tolerance compensation in both the longitudinal and transverse directions of the vehicle. 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.

• - das Fahrzeug mindestens einen Unterboden und mindestens zwei einander gegenüberliegende Seitenwände aufweist,
• - der Fußbodenaufbau mindestens eine Bodenplatte und mindestens einen Fußbodenbelag aufweist, der auf der Bodenplatte aufliegt, wobei
• - die Bodenplatte auf mindestens einem Bodenlagerelement befestigt ist, dadurch gekennzeichnet, dass
• - zumindest die Bodenplatte mit dem Bodenlagerelement eine vormontierte Einheit bildet und
• - die vormontierte Einheit auf dem Unterboden und mindestens einer Ausgleichseinrichtung zum Ausgleich von Toleranzen aufliegt, die an mindestens einer Seitenwand befestigt ist, wobei
• - die Ausgleichseinrichtung in einer senkrechten Richtung verstellbar ist und
• - ausschließlich zwei rechtwinklig zu einander angeordnete Arme aufweist, die ausschließlich für den Ausgleich von Toleranzen vorgesehen sind.

According to the invention the object is a floor structure for a vehicle, wherein

• the vehicle has at least one underbody and at least two opposite side walls,
• - The floor structure has at least one floor slab and at least one floor covering that rests on the floor slab, wherein
• - The base plate is attached to at least one base bearing element, characterized in that
• - At least the base plate forms a preassembled unit with the base bearing element and
• - The pre-assembled unit rests on the sub-floor and at least one compensating device for compensating for tolerances, which is attached to at least one side wall, wherein
• - The compensation device is adjustable in a vertical direction and
• - Has only two arms arranged at right angles to each other, which are only intended to compensate for tolerances.

An advantage of the invention is that tolerance compensation in a vertical direction is made possible by means of the compensation device. The compensation device has only two arms arranged at right angles to one another. The arms are straight, i.e. 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. Compensating device thus has a very simple structure. Due to the compensation device, it is possible to pre-assemble the base plate with the base bearing element, which simplifies the assembly of the base 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 base plate. This simplifies the assembly of the floor structure. Due to the simple construction of the compensation device, an insulation means and / or drainage insulation can also be arranged below the compensation device. The insulation can dampen vibrations and the drainage insulation can wick away moisture.

In a special development of the invention, between at least one end Floor plate and at least one end of the floor covering arranged a transition profile that deflects the floor covering from a transverse direction in a vertical direction. This enables a seamless redirection of the floor covering.

In particular, the transition profile is arcuate. An arcuate design 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 can in the vertical direction to a profile element, e.g. adjoin 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 arranged parallel to the side wall, e.g. an air duct. Thus, at least one gap between the base plate and the profile element is bridged 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 assembling the floor structure, the method comprising the steps:

1. a) fastening at least the base bearing element and the transition profile to the base plate, at least the base plate, the base bearing element and the transition profile forming a preassembled unit,
2. b) adjusting the compensation device in the vertical direction and attaching the compensation device to the side wall,
3. c) Place the pre-assembled unit on the sub-floor and on the compensation device
4. d) attaching 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. The transition profile is also pre-assembled.

In addition, in step a) the floor covering can be attached to the floor slab and to the transition profile. 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). 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 sub-floor between step b) and step c). Due to the geometry of the compensation 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 compensation device for the second insulation medium.

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 is a floor structure according to the invention 10 exemplified in relation to a rail vehicle. The rail vehicle has an underbody 20 and a side wall 21 on and is not otherwise shown. The floor construction 10 is only in the area of a side wall in the figure 21 shown. The floor construction 10 is in the area of one of the side walls 21 opposite other side wall constructed accordingly. The floor construction 10 is thus in a transverse direction y installed symmetrically in the rail vehicle. A longitudinal direction x of the rail vehicle corresponds to a direction of travel.

The floor construction 10 points in the area of the side wall 21 a floor support element 30 on that on the underbody 20 is arranged. A floor slab 31 lies on the floor support element 30 on. Between the underbody 20 and the bottom plate 31 are a first means of insulation 40 and a first drainage insulation 41 arranged. The first insulation agent 40 is between the bottom plate 31 and the first drainage insulation 41 arranged that on the sub-floor 20 rests.

A floor covering 50 lies on the base plate 31 on. An end 51 of the flooring 50 is at one end 32 the bottom plate 31 diverted. Here is the floor covering 50 on a transition profile 52 guided. The transition profile 52 is at the end 32 the bottom plate 31 attached. The transition profile 52 borders on a seal 53 on. The seal 53 seals the floor covering 50 opposite a profile element 60 , for example a channel element.

In addition, the floor structure 10 in the area of the side wall 21 a compensation device 70 on. The equalizer 70 here is an angle element with a first arm 71 and a second arm 72 , the first arm 71 and the second arm 72 form a right angle. The first arm 71 is by means of a fastening unit 73 , for example a screw connection, on the side wall 21 attached. The equalizer 70 is together with the fastening unit 73 in a vertical direction z movable, for example in an elongated hole 22 the side wall 21 , On the second arm 72 is the end 32 the bottom plate 31 on. The bottom plate 31 can, for example, with an adhesive 74 on the second arm 72 be attached. Between the compensation device 70 and the underbody 20 are a second means of insulation 80 and a second drainage insulation 81 arranged. The second insulation agent 80 is between the compensation device 70 and the second drainage insulation 81 arranged that on the sub-floor 20 rests.

When assembling at least the bottom plate 31 , the floor bearing element 30 and the transition profile 52 preassembled. Also the first insulation agent 40 can on the bottom plate 31 be pre-assembled.

The first drainage insulation 41 can on the first insulation 40 be pre-assembled. The flooring 50 can also on the base plate 31 be pre-assembled. The seal 53 can on the transition profile 52 be pre-assembled. Overall, a large part of the floor structure 10 be installed as a preassembled unit in the rail vehicle, the preassembled unit being held together by at least one adhesive.

Before installing the pre-assembled unit in the rail vehicle, however, the compensation device 70 in the vertical direction z can be set. There must also be a corresponding additional compensation device on the side wall 21 opposite other side wall in the vertical direction z can be set. With the help of the compensation device 70 and the other compensation device, tolerances are compensated or leveled when installing the preassembled unit. The bottom plate 31 then assumes a horizontal position, whereby a predetermined tolerance range is maintained. If the equalizer 70 and the further compensation device are set, the second insulation means 80 and the second drainage insulation 81 be installed, namely on the side wall 21 and the side wall 21 opposite other side wall.

The first insulation agent 40 and the second insulation agent 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 be different in different rail vehicles and adapted to different installation conditions. A weight of the pre-assembled unit can be determined by determining the size of the base plate 31 to be controlled. Installation of the preassembled unit shortens assembly times for the floor structure in a final assembly, ie when it is installed in the rail vehicle.
