In order to improve the body in such a manner that a more simple method of production can be achieved which also results in a reduction in the dead weight whilst the stability is at least as high as previously, the edge parts (3), which are bent upwards, of the floor (1) merge into flange-like edge parts (1) which are in each case angled outwards, and furthermore the reinforcements of the side walls are designed as beads (6) which extend over the entire height thereof, and the side walls are welded by their end sides onto the flange-like edge parts (4) such that they are supported against the latter. <IMAGE>

Description

The invention relates to a structure for trucks, especially swap bodies, especially for bulk goods goods, consisting in particular of approximately a cuboid shaped, above, especially open box, in particular with an opening rear wall, the bottom of which at least long angled or rounded abge has curved edge parts on which the side walls are attached, which are a variety behind distributed in the longitudinal extension of the side walls arranged, upright stiffeners.

In box-like structures known from practice made of sheet steel of this type for trucks that are primarily used for Transport of bulk goods are intended, the longitudinal angled upwards or rounded Bottom edge parts favor emptying of the superstructure, and the superstructures also releasably attached to the vehicle can be to match them each against a like or exchange another structure can, the box side walls have one after each inside cranked end part, which on the inside of the after Above the bent bottom edge part attached is welded.  

In addition, are outside the box-like structure these underneath and laterally, in the Areas of the side walls of vertically oriented frames welded from U-shaped bars, the latter with the free flange edges on the outside of the body issue.

Here, however, arise between the box and inaccessible to its frames, inaccessible against rust formation protected and cannot be retrofitted from rust Cavities, in the areas of which rust formation increases starts.

In addition, the manufacture of such structures relatively complex. The dead weight is also one such a structure is relatively large.

The object of the invention is now to build a Trucks in the preamble of the claim specified type to improve such that under Ver better protection against corrosion a simpler Manufacturing is achievable, which at least  same stability as previously a Ver weight reduction results.

The solution to this problem is characterized by that the upturned edge parts of the floor in flange-like angled outwards Edge parts pass over, also the stiffening of the Side walls than over their entire height stretching beads are formed and that the sides walls with their end faces on the flange-like Support edge parts and welded to the latter are.

These measures are now so far not avoidable cavities both inaccessible from the outside in the areas of wall stiffeners as well as in the areas of connection between the Box bottom and the box side walls avoided, so that now the construction of a complete and everyone allows repeatable rust protection.

In addition, the manufacture and the right are unnecessary elaborate assembly of the previously required wall stiffeners.  

The outward angled flange also results like bottom edge parts a significant increase the shape stability of both the box bottom and of the box side walls, without the material to increase effort significantly. In addition, the bead-like stiffeners in the To produce side walls extremely cheap to manufacture, because flat sheets only on the respective one Places must be folded.

To further simplify manufacturing, it is advantageous if the flange-like edge parts for Box bottom are angled parallel to each other, so that when arranged at right angles to the box floor Side walls whose end faces are only rectangular need to be integrally molded.

For an even greater dimensional stability of the structure namely in the area of the connections between the To reach the box bottom and the box side walls, it is advantageous if the side walls with the flange-like edge parts on at least one side, especially on the outside by means of complete, over the entire length of the weld seams  are connected and that the side walls on the other Side, especially inside at least in the Areas of the bead back to the flange-like Edge parts are welded.

As a result, the box floor facing End parts of the side walls by means of both sides arranged weld seams clamped on the box bottom, resulting in a significant increase in bending strength results.

Other features to increase the dimensional stability are disclosed in claims 4 to 6.

An advantageous development of the box bottom is that this including the bent Edge parts running longitudinally and over its entire Has width distributed beads.

Preferred configurations of the beads are in the Claims 8 to 11 disclosed.  

Another, possibly preferred design the box-shaped structure is characterized by that the box side walls made of one piece, profiled box-like and in particular further by additionally molded, longitudinal webs stiffened plates, in particular made of light metal are composed and that in particular the Box bottom made of the same material as the box side walls.

It is also possible to use the box side walls Box bottom with its insides on the edge parts of the Welded to the bottom of the box, where especially the box side walls over the aforementioned welds down from above can be formed.

Embodiments of the invention are in the Drawing shown and will be described in more detail below described.

Show it:

Figure 1 shows a part of a box-like structure in a perspective view.

Figure 2 shows a part of a variant in cross section.

Fig. 3 shows another embodiment in the same view as FIG. 2.

In all embodiments, the box-shaped structure made of sheet steel, especially for trucks, which is primarily intended for the transport of bulk goods and can be fixed to the chassis as well as releasably, from a one-piece box bottom 1 and attached to these side walls 2 .

The box bottom 1 has at least on the long side obliquely angled upward edge parts 3 which merge into flange-like edge parts 4 running parallel to the flat bottom part. Edge strips 5 are bent vertically downward from the latter.

The side walls 2 have extending over their entire height, vertically directed, and distributed over the entire length of the side walls is arranged, pressed through beads 6 and are each welded with their lower end faces on the edge parts 4 standing up.

For this purpose, seamless weld seams 7 are provided on the outside over the entire length of the side walls 2 . On the inside, only weld seams 8 are provided in the areas of the bead backs. It is also possible to weld the side walls 2 to the inside of the edge parts 4 by means of weld seams extending over their entire length.

According to FIG. 2, the edge parts 3 are rounded upwards and the width of the edge parts 4 corresponds to the thickness of the side walls 2 including beads 6 . Furthermore, the side walls 2 are arranged so that they are flush with the edges of the skirt 4 . In addition, here the edge strips 5 extend to approximately the flat base part and end in the edge part 9 which is bent inwards at right angles.

According to FIG. 3, the box base 1 is Lich Enclosure of the edge portions provided with longitudinally extending beads 10 3 and 4. The channel width of each bead 20 corresponds to the thickness of a side wall 2 including beads 6 and the side walls 2 are each inserted with their lower end parts into the beads 10 arranged in the edge parts 4 and open at the top, with the side walls 2 including beads 6 adjoining the Support flanks of the beads preferably frictionally, so that the side walls are already clamped in the beads 10 before the welds 7 and 8 are applied.

The bottom 1 is still supported by means of cross struts 11 which are distributed over the length of the box-like structure and which preferably have a U-profile.

According to Fig. 1 of the floor 1, two longitudinal carriers 12 are attached I-shaped profile at the bottom, which cross-struts carry. 11 This box is intended for detachable and interchangeable arrangement on a chassis. In the case of superstructures permanently connected to the chassis, the carriers are attached a priori to the chassis. The boxes 1 , quasi any base area, can also be closed at the top or designed to be lockable. Under certain circumstances, it may be advantageous to profile the beads 6 in a substantially semicircular or triangular manner.

All new, in the description and / or drawing disclosed individual and combination features regarded as essential to the invention.
