Dowel for positive fixings on gas concrete structures - has reinforcement rods driven hooked shape into concrete without expanding pressure

摘要

The dowel for fixing items on gas concrete structures has a basic element which has at its point a moulded sleeve (3) and bending faces (8) spread round the circumference. Reinforcement rods (5) are fixed evenly spread round the circumference on a counter member. These rods are guided through the moulded sleeve and are pressed out over the bending faces hook-shaped as the tension screw is tightened. The reinforcement rods can have a slide radius and a point at their free ends. ADVANTAGE - The rods engage in the brickwork as the screw is tightened to produce a stable positive connection without expanding fores which could break down the brickwork.
