Embodiment Construction

[0025] Figure 1-3 An adhesive connection and a method for producing the adhesive connection according to the invention are shown.

[0026] There is an adhesive connection between the first hollow profile 1 and the second hollow profile 2 , wherein the second hollow profile 2 is surrounded by the first hollow profile 1 in the overlapping region. The second hollow profile 2 is thus inserted into the first hollow profile 1 in each case.

[0027] A core 3 is arranged in the overlapping area within the first hollow profile 1 and the second hollow profile 2, which core 3 is connected to the first hollow profile 1 by means of a cover or base 7 and is cuboid-shaped or made of foam material. Cubic solid. This core 3 has four boundary surfaces 4 as side walls, which are arranged in a parallel and immediately adjacent manner in each case to an inner side 6 of the second hollow profile 2 . An adhesive 5 is introduced between the core 3 and the inner side 6 of the second hollow profile...

Abstract

The invention relates to an adhesive connection of a first hollow profile (1) to a second hollow profile (2), wherein the second hollow profile (2) is replaced by the first hollow profile (1) in an overlapping region Surrounding, wherein a core (3) connected to said first hollow profile (1) is arranged in said overlap region within the first hollow profile (1) and the second hollow profile (2), wherein said core The part (3) has at least one boundary surface (4) arranged substantially parallel to and adjoining the inner side (6) of the second hollow profile (2), wherein the adhesive (5 ) is arranged between said core (3) and the inner side (6) of said second hollow profile (2); and a method for producing an adhesive connection.

Description

technical field [0001] The invention relates to an adhesive connection of a first hollow profile to a second hollow profile, wherein the second hollow profile is surrounded by the first hollow profile in an overlapping region. Background technique [0002] Connected hollow profiles can be used to manufacture eg load-bearing structures of motor vehicles, in particular body structures of the known "space frame" type. [0003] In order to connect two hollow profiles, it is known to insert one hollow profile into the other, for example to weld, clamp or glue the two hollow profiles in the overlapping region. However, simple adhesive connections are only moderately reliable, especially in the case of imprecise or twisted installation of the hollow profiles. [0004] For example, DE 10 2006 044 799 A1 discloses a body module for a motor vehicle with a plurality of load-bearing profiles connected together and whose load-bearing ends are to be inserted into receiving holes, further...
