GLUE ANCHOR FOR CONCRETE, STONY MATERIALS AND WOOD.

摘要

This fastener (1, 10) has a number of circumferential collars (3, 13), the lateral sides (5, 15) of which include an obtuse angle with the adjacent shank periphery. Thereby an equal stress distribution in the adhesive layer and a larger holding force are achieved. Fasteners for securing building parts have a 105 DEG obtuse angle, whereas fasteners especially adapted for securing rail carriers have a 135 DEG angle.
