DE2510211C3 - Wall component made from partial profiles - Google Patents

Description

The invention relates to a wall component made of partial profiles that lie next to one another at their edges are connected to each other, in which at the respective joint of two partial profiles a shape and non-positive connection by embedding a hook-like attachment of one partial profile in a groove of the second partial profile is provided, the groove and the hook-like projection in the surface extension are inserted into each other in the perpendicular direction.

With such a wall component according to DT-AS 23 44 638, there are two at the respective joint Partial profiles of the hook-like approach of a partial profile has a bead with such ribs that he opposite the Groove opening of the second partial profile is an oversize required to produce a cold pressure welded connection having. This wall component therefore requires a highly dimensionally accurate and form-free one Formation of the associated edges of the partial profiles.

The invention is based on the object of providing a wall component of the type mentioned at the beginning create, in which a special dimensional accuracy of the hook-like approach on the one hand and the groove on the other is not required.

This object is achieved according to the invention in that the embedding of the hook-like extension is thereby achieved the effect is that of the groove edge overlapped by the hook-like approach nipht material of the respective partial profile into the groove space remaining after the hooking and at least partially over the hook-like approach is shifted.

Accordingly, the anchored part of the profile in the groove of the second profile by a thereto profiled only after the entanglement due to the displacement of material approach the Wandungsbauteil according to the invention, the hook-like approach, it has been found that then, for example by means of a conventional compression machine not only the desired form - and non-positive connection at the respective joint between two partial profiles can be produced without any problems, but a smooth outer surface of the wall component can also be achieved there The invention is particularly suitable for the mass production of freight containers. However, the invention is not limited to this. Under wall components, not only all walls of a freight container, such as front, side walls, roof and floor are to be understood within the scope of the invention but also, for example, pallets, parts of vehicle superstructures for both freight and passenger traffic, parts of bridge structures, formwork components for civil engineering and the like.

For this purpose, in a further embodiment of the invention, a material shift by cold deformation is to be allowed prefer, whereby it is expedient on the one hand to use the material used for embedding prior to embedding the hook-like approach provided in the form of a bead extending the groove wall and on the other hand the hook-like approach to the formation of it in the direction perpendicular to the surface extension in the groove holding approach is notched accordingly.

Embodiments of the invention are explained in more detail below with reference to the drawing. It shows

F i g. 1 in section two partial profiles in the area of a joint,

F i g. 2 the joint according to FIG. 1 after establishing a connection between the partial profiles, F i g. 3 in section designed as a chamber profile Partial profile and

4 shows a joint between two partial profiles according to FIG. 3.

According to FIG. 1 are two sub-profiles 1 and 2 to be connected to one another, for example extruded profiles, hooked into one another at their edges by means of hook-like lugs 3 and 4, respectively. This remains between the two Partial profiles 1 and 2 in the area of the outer surface 5 have a groove space 6. The groove space 6 has a wedge-like shape Bevel 7 on the one partial profile 1 or his

so approach 3 such a cross-sectional shape that a filling of this groove space 6 to anchoring this Partial profile 1 or its approach 3 in the second partial profile 2 leads. The prerequisite for this is of course a Bonding between the filling material used and at least the second partial profile 2. Around this To obtain material connection, a bead 8 is provided in the second partial profile 2, which the outer surface 5 of the Partial profiles or the wall component to be formed therefrom protrudes. The material forming the bead 8 is therefore used to fill in the remaining groove space 6 after the partial profiles 1 and 2 are hooked. this is preferably done by upsetting the second partial profile 2 in the area of the bead 8, for. B. by means of a Riveting hammer. According to FIG. 2, the result is the formation of a second projection 9 on the second partial profile 2 such that that this approach forms an abutment for the interlocking of the two partial profiles. After upsetting the second Partial profile 2 is therein the first partial profile 1 with his

hook-like approach 3 embedded.

In the multi-chamber profile shown in Figure 3 two hook-like lugs 10 and 11 are provided on both narrow sides, preferably in the form of racks. In this case, the lugs 10 and 11, which are opposite one another in pairs, are in each case formed identically, but this is not binding. A bead 12 is located in each case in the area of the attachment 10, which after hooking with a hook-like extension 11 of a second partial profile this together anchored to the approach to be formed from the bead 12. This is shown in FIG. 4 for a joint before the

Immersion of the bead 12 in the groove space 13 remaining between the two partial profiles is shown it can be seen that in the approach to be anchored 11 of the one partial profile of the relevant longitudinal edge 14 is concave. 1 shown Wedge-like bevel 7 is therefore not binding, but rather is decisive for the respective approach to be anchored U only that its the bead 12 opposite longitudinal edge 14 when dipping the bead into the remaining groove space 13 to form an abutment for the interlocking of the two lugs 10, 11 effective third approach
