Kind Code:
A
Abstract:
The invention relates to an expansible fixing plug (10) having an expansion screw (14), which is located in an expansible fixing plug sleeve (12). In accordance with the invention, a screw thread (30) is of saw tooth construction and a rear part (16) of the fixing plug sleeve (12) is axially extendable. When the expansible fixing plug (10) is subjected to axial loading the expansion screw (30) moves axially in the fixing plug sleeve (12) and the screw thread (30) expands the fixing plug sleeve (12). The expansible fixing plug (10) therefore has a subsequent-expansion behaviour when a drilled hole becomes enlarged. A further advantage of the invention is the mounting of the expansible fixing plug (10) by hammering in without turning the expansion screw (14). The core diameter of the screw thread (30) enlarges from the front to the rear to increase the capacity of the expansion screw (14) to withstand transverse loading. (FIG. 5).
