Tie-bar fastening element for linking a tie-bar to a wall set vertically to it penetrates a hole in a wall with inner and outer bearing surfaces

摘要

A tie-bar fastening element (10) is designed to penetrate a hole (12) in a wall (14). Fitted parallel to each other and with a gap corresponding to the wall's thickness, an inner (20) bearing surface (BS) lies on the wall's inner side (18) facing the tie-bar and an outer (22) BS lies on an outer side (16) opposite the tie-bar. A slot (26) runs through the outer BS.
