Two-part joining element and method for any kind of prefabricated hole free making a mold - and non-positive joint, and thus manufactured composite component structure

摘要

The present invention relates to a two-part joining element (10) for any kind of prefabricated hole free making a mold - and non-positive joint between the at least two components (40, 50), with:– a nail-like outer part (20) comprising a shaft with a head (22) and the tip (23), wherein the shaft as the hollow shaft with a top opening is formed; and– a pin-like inner part (30) which, via the head opening in the hollow shaft of the outer part (20) and can be driven in this case, the upper material at the tip (23) is displaced to the outside and is plastically deformed.The present invention also relates to a method for any kind of prefabricated hole free making a mold - and non-positive joint between the at least two components (40, 50) with the use of an insert element (10) and a composite component structure produced (100).
