Problems solved by technology
[0002] Fixing of fittings is known to be difficult on lightweight construction panels because the intermediate layer provided with cavities is not suitable for carrying the forces
The problem thus far, especially on the end side, is to fasten the fitting in an efficient manner with high strength
In addition, the introduction of the adhesive is also difficult, since the thickness of the intermediate layer can deviate due to tolerances and thus strongly alter the quality of the adhesive connection
Last but not least, inaccessible bonding for automated manufacturing parts

Embodiment Construction
[0034]The lightweight construction panel 1 comprises two outer cover panels 2, 4, between which an intermediate layer 3 with cavities is arranged, which is produced, for example, as a honeycomb panel made of cardboard or plastic . The cover sheets 2 and 4 can likewise be made of cardboard or plastic and have a higher strength than the middle layer 3 . In order to fasten the fitting 10 on the end face 6 of the lightweight construction panel 1 , a hole 5 is formed in the end face 6 , which hole has a circular cross section. Here the bore 5 is designed such that a part of the bore is formed on the inside into the outer cover plates 2 and 4 , so that a curved wall section 8 is formed on the cover plates 2 and 4 . The cover plates 2 and 4 generally have a thickness between 1.0 mm and 10 mm, so that the holes are cut into the cover plates by 0.2 mm to 5 mm, preferably 0.2 mm to 1.5 mm.
[0035] The fitting 10 made of plastic or metal comprises a housing ring 11 which can be insert...

The invention relates to a method for fixing a fitting to a lightweight board, and to a corresponding device. According to said method, a lightweight board (1) is first fixed to a fixing device via two outer cover boards (2, 4) and a center layer (3) and at least one front bore (5) is incorporated thereinto a section of the bore channel of which engages in a cover board (2, 4). A fitting (10) is inserted into the bore channel. Glue is injected into the fitting (10) into a glue chamber (13) which is partially delimited by the wall (8) of the bore channel in the region of the cover board (2, 4). Fittings can thus be effectively mounted to the front faces of lightweight boards (1).
Description
technical field [0001] The invention relates to a method for fastening fittings to lightweight construction panels, a device for carrying out the method and a lightweight construction panel with fittings. Background technique [0002] It is known to be difficult to fasten fittings on lightweight construction panels, since the intermediate layer provided with cavities is not suitable for absorbing forces. The problem thus far, especially on the front side, is to fasten the fitting in an efficient manner with high strength. Previously, the fitting was glued on the inner side of the cover, which enabled a direct connection of the fitting to the two cover. Of course, here too the strength is limited, since the planar arrangement of the cover can absorb forces only to a limited extent in the plane of the cover. Furthermore, the introduction of the adhesive is also difficult, since the thickness of the intermediate layer can deviate due to tolerances and thus drastically alter t...
