摘要

The anchor (1), for the reinforcement of a concrete construction block (25) with an overhang arm (12) projecting from one side, has a shaft (2) with an anchor head (4) at its end (3). The other end of the shaft is within an anchor sleeve (22), bonded to the concrete reinforcement rods (11). The anchor head has a rectangular ground surface (5) with long and short sides. The length of the long sides is about 1.5 times the width of the short sides.
