  • Anchorage system of the elements to be supported on the completed structure
    Patent number: 4316689
    Abstract: An anchoring system is provided for use in building walls. A drill hole is formed in a wall or floor with a radially enlarged portion. A fixing bolt bearing an anchoring sleeve and a threaded piece is inserted into the hole. The anchorage sleeve having radially outwardly extended projections flexes upon insertion into the hole to expand these projections into the enlarged portion and a control element is rotated to move a threaded piece interconnected with the anchoring sleeve into the lower end of the anchoring sleeve. The system provides a more reliable anchor than conventional adhesive bolts or expansion bolts.
