DE19602942A1 - Floor for railway goods wagon - Google Patents

Abstract

The flooring element (1) is propped up from the wagon's bogie by a frame. It is self-supporting, being supported only in its edge areas on the frame. It has at least two cover layers between which a grid (4) is located which keeps the layers apart. The grid has spaced strips which interlock and form a mesh with cells (8). The floor is closed by strips (7) encompassing its edges. Recesses are formed at the crossover points of the strips.

Description

The invention relates to a floor element for rail freight cars, which on the The base frame is supported by a supporting structure.

So far it is known, for. B. from DE 30 41 193 A1 or DE 3 82 308 A1 under the floor of rail freight wagons has a relatively narrow structure To arrange steel beams. The structure has essentially the load from the Support the base plate and the load. On the one hand, training requires egg nes diversified structure a considerable manufacturing effort and others On the one hand, a heavy structure noticeably reduces the transportable payload.

The invention is therefore based on the object of a floor element for To create floor of rail freight wagons, which is simple and easy lighter design of the structure of the base frame of the freight car, on the other hand can take the necessary loads.

This object is achieved by the teaching specified in claim 1.

Advantageous further developments are specified in the subclaims.

An embodiment of the invention is below with reference to the drawing described in more detail.

Figure 1 is a plan view of a floor element.

Fig. 2 is a cross section through the floor element according to the line AA of Fig. 1;

Fig. 3 is a partial section along the line BB of Figure 1 in an enlarged view.

Fig. 4 is a side view of one half of a rail freight car with floor elements and

Fig. 5 is a plan view of the half of the railway goods wagon according to the Fig. 4.

A floor element 1 is self-supporting and has an upper cover layer 2 and a lower cover layer 3 , the grid 4 are held at a distance by an intermediate web. The web grid 4 has grid strips 5 arranged at a distance from one another, which are connected and interlocked with grid strips 5 arranged perpendicularly thereto. The toothing takes place at the crossing points of the intersecting grid strips 5 through recesses 6 in the grid strips 5 . The lattice structure of the floor element 1 is closed at the edges by edge strips 7 .

The cover layers 2 , 3 are firmly connected to the web grid 4 or the grid strips 5 , in particular by gluing or gluing.

The chambers 8 of the floor element 1 formed by the lattice structure are connected to one another via ventilation gaps 12 in the grid strips 5 for air circulation.

At least two openings 13 are provided in the lower cover layer 3 and / or in the edge strips 7 . The openings 13 connect the chambers 8 to the ambient air and ensure drainage (condensed water, penetrated water) of the floor element 1 via air circulation.

The lower cover layer 3 is made of plywood or sheet metal (steel or aluminum sheet).

An economical floor element 1 preferably has cover layers 2 , 3 made of higher quality plywood (e.g. birch plywood) and grid strips 5 made of less valuable plywood (e.g. spruce plywood) or sawn timber.

To form a floor of a rail freight car several Fußbo denelemente 1 are arranged side by side and only supported at their peripheral areas in the base 9 . The base frame 9 of the rail freight wagon has only two outer long beams 10 , between which 1 cross beam 11 are arranged with the grid width of the floor elements. The floor elements 1 rest on these supports 10, 11 . Inner long beams are eliminated.

The dimensions of the floor element 1 are dependent on the gap to be bridged between the outer long beams 10 and the chosen width grid. The thickness of the floor element 1 is approximately 10 cm. A practice-oriented width grid is approximately 150 cm. A practical Längenabmes solution and thus the distance to be bridged between the long beams 10 is about 180 cm.

For higher loads, a floor element 1 can have more than two cover layers 2 , 3 , each of which is kept at a distance via a web grid 4 . A formation with an upper cover layer 2 , a lower cover layer 3 and a middle cover layer requires two web grids 4 .

The upper and lower cover layers 2 , 3 are coated on their outer surfaces with plastic. On the one hand, the wear resistance and service life of the Fußbo denelements 1 and on the other hand, the quality of use is increased.
