FASTENING ELEMENT AND METHOD FOR FASTENING GUARD ELEMENTS ON A SUBSTRUCTURE

摘要

The present invention relates to a fastening element and a method for fastening guard elements on a substructure. In order to provide an improved fastening element for fastening guard elements, it is suggested within the scope of the invention that the fastening element consists of a shot-fire element and a collar screw connection, wherein the shot-fire element has a tip and a body with an external thread, and the collar screw connection has a blind hole with an internal thread that corresponds to the external thread of the shot-fire element, thereby enabling the shot-fire element to be connected to the collar screw connection. The guard elements, which have a circumferential collar, are placed on a substructure, in particular a steel structure such as a double-T beam, and subsequently anchored by means of fastening elements. For this purpose, the shot-fire element is fired into the substructure (steel substructure) by means of a stud gun such that the tip penetrates into the substructure. This results in a form-locked and captive connection between the shot-fire element and the substructure.
