A method for inserting and fixing of a fastening of a sentence in a lightweight construction - sandwich plate and fastening of a set

摘要

Disclosed is a method for inserting and fixing of a fastening section a countersink having a set in a middle layer and two on the middle layer in each case on mutually opposite main faces having outer layers applied lightweight construction - sandwich plate by means of adhesive technology, in which, by removal of material extending in the depth of the middle layer, the middle layer is not completely introduced and the fastening recess which projects through a set into the recess is inserted and glued there. In order, in the case according to the previously known processes fixed attachment of an etching in the case of a tensile load of such an insert having a resistance occurring depressions image on the opposite cover layer is to avoid for the process, it is proposed that the recess up to a bottom of the same by means of a depth in the material of the middle layer is guided, which extends further than a length of the countersink is to be received in the recess portion, and that in the case of the adhesive bonding of the fastening, a set of an air gap between a facing the base of the recess end face of the countersink section and the bottom of the recess is left is arranged in which no adhesive. The air gap is achieved by means of a decoupling, so that the tractive force is no longer to be forwarded to the opposite cover layer, the undesired dell education does not occur.
