These truncated legs 4 'are with their adhesive-coated outer sides with the bottom part 1 ^T, 1 "of the pallet or glued to the bottom of a container or box ■. In Fig. 9 is 4 by lüinwärtsbördelung of the edges" of the shortened legs 4 ^T a greater depth of the longitudinal groove 7 is reached.

The with the bottom of a pallet or a container \ resp. A box to be glued sides of the support beams 2, have permanent adhesive surfaces 5. The latter are protected from gluing in a known manner by easily tearable cover films.

Figs. 11 and 12 show a container, respectively. a box 9, the bottom of which is divided by two inner and two outer, each opposing each other, is formed as flaps arranged bottom parts 9 ', 9 ". The bottom parts 9" carry the support beams 3 and two outer bars and a two-part middle bar. The outer bars 3 are on the outer longitudinal edges of the Container fixed by gluing. The middle support beam is formed from two equally long beam parts 13, which in the In the closed position of the base parts 9 ″ coaxially adjoin one another and cover the parting line 10 between the two bottom parts 9 ″. One beam part 13 is on the bottom part facing left 9 ″ and the other beam part attached to the facing right-hand bottom part 9 ″ by gluing with their adhesive side 4. the Beam parts 13 each have an extension 14 on their outer legs 4, which serve as an adhesive flange and a better one

Purpose of the holder on the bottom part. In the support beam 3, in turn, a stiffening element 6 is inserted, which the two Parts 13 of the middle support beam 3 connects to one another, so that the base parts 9 ″ each carrying a beam part 13 are in their Are locked in their closed position. The top of the container can be closed in a conventional manner. That is of course Support accessory more for containers etc. with large volumes and weight suitable, which are transported by forklifts. When pulling the associated stiffening element out of the beam 3 up to the parting line 11 or by pulling it out completely, the connection between the beam parts 13 is canceled, so that the bottom parts 9 ″, each of which carries a beam part 13, can be pivoted into their open position can, as stated above, the support beams 3 fold flat. To enable the stiffening elements to be pushed in easily 6, these have bevels 15, 15 '(FIGS. 4 and 7) on one end side on the longitudinal sides 6 "and on the apex.

The container 9 according to FIGS. 13 and 14 is stranded with three support beams 3, each of which has two separate beam parts 13, which ' the latter on the outer base parts 9 "across to their hinged bolts are glued on. Each bottom part 9 ″ carries, as FIG. 14 shows, three bar parts 13, which are in the closed position of the bottom parts 9 ″ by inserting stiffening elements 6 each combine to form a single support beam 3, which is the length of an overall beam 3 have, and are rigidly connected to one another in the position of use.

and are each divided in half their length. The one beam part 13 is connected to one half of the pallet and the other beam part 13 to the other half of the pallet. With the through Insertion of the stiffening elements 6 achieved connection of the two-part beams 3, the pallet 1 is also given a solid structure. Folded pallets can be stacked on top of one another when not in use, requiring little space. When the Pallet, according to FIGS. 16 and 17, the support beams are of course also folded flat.

The described support additive for transport props is particularly characterized by its surprisingly high strength against stress on tension, vertical and side pressure, bending and torsion. It is cheap in price and allows a transport prop can be thrown away after only a short period of use. The support additive and the associated transport accessories can be impregnated so that they can be exposed to the elements. The collapsible support beams can also be sold individually because the attachment to transport props such as pallets, boxes, containers, etc. is very easy due to the easy attachment option by gluing.

A V-profile according to FIG. 18 or an element composed of two V-profiles according to FIG. 19 can serve as a stiffening element for insertion into a support beam 3 and 4 designed as a square hollow profile. For the creation of clean folded edges, especially vertex edges 6 ^! the V-profiles 6 are on the surface of the corrugated ^{cardboard blank 1 T} serving as the hollow profile inside for a stiffening element 6 or a support beam 3 rabbet grooves 7,

For the engagement of the apex edges 6 ^{T of} a V-profile stiffening element 6 according to FIGS. 18 and 19, grooves 7 are also grooved and pressed in at the corresponding points on the inside of the hollow profile of the support beam 3. These guide channels 7 facilitate the insertion of the stiffening element 6, on the one hand secure its position in the support beam 3 and on the other hand stiffen the cross-sectional shape of the support beam. By attaching folds 7 ^! On the vertical side walls of the support beam 3 according to FIG. 20, it is achieved that when the load is high, the side walls do not bend outward but inward and thus bring about an even better holding of the stiffening element. The absorption of the loading pressure on the beam 3 is in any case left to the stiffening element 6 alone. Since the stiffening elements have to withstand the entire load pressure, in most cases only a double or multi-walled corrugated cardboard of high quality is sufficient for their production, such as the "corrugated fiber board" or the like known in specialist circles. Thanks to the absorption of the entire load pressure by the stiffening elements, the wall thickness of the support beams 3 can be kept relatively very thin. For this reason, a fine-wool to ultra-fine corrugated cardboard (called B- and Ε-wave in professional circles) corrugated cardboard can be used. However, this must be of good quality, since it is subjected to both mechanical and tensile loads on the bottom surface of the support beam. A perfect folding of the support beams can only be achieved by using single-wall, thin types of corrugated cardboard.

Instead of a V-profile, a triangular profile according to FIG. 22 can also be used as the stiffening element. This forms a self-contained, rigid triangular profile 17, in which the apex edge 6 ^! is supported by vertical strut parts 17 '. The triangular profile 17 is bent from a piece of overall ¹ by the through five Falzrinnen 7 six partial strips forming corrugated cardboard blank is bent together 1 ^T three angles of 60 and subsequently through two angles of 90 ° so that the two end tabs 17 ¹ a Form the height support of the isosceles profile % triangle.

To enable the stiffening element to be pushed in unhindered 6 in the support beam 3, the edge corners can be rounded on at least one of the two end faces 15, Fig. 22 should be eliminated. These corner roundings 15 can of course also be made on the V-profiles 6 according to FIGS. 18 and 19.

The support device formed by stiffening elements is particularly suitable for pallets, containers and pallet boxes, on which they can be attached to any desired shape thanks to their square cabbage profile Place of the floor of a transport prop can be arranged and furthermore, thanks to a diagonally bracing stiffening element, the square carbon profile has a high load-bearing capacity.

Supporting beams and stiffening Salem duck may be preferably made of waterproof Materialein, such as both sides impregnated W or plastic corrugated cardboard, but furthermore also made of plastic, wood or sheet metal.

The diagonal bracing of the square hollow profile through the stiffening element is secured by the engagement of the longitudinal edges of the latter in channels on the inside of the hollow profile. The latter fix the stiffening element in its most effective position. The guide channel takes on the function of the pressure axis, which enables the self-bracing effect of the stiffening element with increasing pressure load. Thanks to the guide channel is ⁴ : the stiffening element can be pushed quickly and safely into the support beam.

The stiffening element can be a V-profile or triangular profile, which has two side legs standing at an oblique angle, be formed. It can also be made up of several adjacent or produce a coherent triangular door profile.

A V-shaped stiffening element made of two-layer or multi-layer corrugated cardboard is characterized by its surprising load-bearing capacity, is torsion-resistant, light and comes with a lot of

times cheaper to stand than a conventional stiffening element made of stacked corrugated cardboard lamellas; in addition it is in non-use state, i.e. if not yet inserted or removed, very space-saving.

Since especially the containers in the area of their outer walls have the best static properties and small-sized containers the gaps between the support beams would become too narrow for effortless manipulation with forklift trucks, were according to the invention the polygonal hollow profile having support beams in a ring | shaped system, be it as a prefabricated, closed Unity, be it with an interspace forming the guide trough, in order to ensure that the supporting beams are statically and functionally at their disposal can be fixed in the most favorable position. '

Since it has been shown several times that moisture is the greatest enemy of corrugated cardboard, it was provided that both the support beams as well as the stiffening elements through suitable measures such as impregnation, coating on both sides with plastic, etc., through waterproof cladding with conventional packaging machines and " -Systems, such as electrostatic welding in waterproof films, shrink films, etc. or by attaching special Protective devices are protected.

It appears to be particularly useful for multiple use of the transport props provided with the support device also to use other liat ^ rials instead of corrugated cardboard, which are Thanks to their special properties and processing options, they are suitable for the manufacture of support equipment, such as

In the case of two-part support beams arranged on the bottom flaps of containers, the stiffening elements are pushed in a double! function is achieved, namely both the perfect Longitudinal and cross bracing as well as a solid, fast bottom closure.

Two or more transport props provided with carrying beams such as containers, e.g. containers, boxes can be effective by inserting correspondingly long, continuous stiffening elements be coupled together to form a detachable unit. This is because it is desirable for several small containers to be transported to one transport unit join together to save loading manipulations.
