Hollow peg for anchoring thin-walled plates used in construction - comprises sleeve and hood parts which are connected by interlocking conical fingers

摘要

The hollow plug comprises two connectable parts which are a sleeve or jacket under part and a hood or bonnet upper part. The two parts grip each other at the edges of the jacket. On the inner walls of the parts are offset fingers which link together. The fingers are conical and taper towards their distal end. The fingers are placed at the base or foot end of the plug which connects to the top part with a press-fit connection through a plug screw with plug guides in the cross-axis. The plug wall inner side lies against the fingers and provides a counter force in the longitudinal axis of the plug.
