  • Patent number: 6327829
    Abstract: A connecting structure of concrete block according to the present invention comprises connecting rods buried in divided blocks, and a connector which exerts forces to attract exposed ends of the connecting rods toward each other and maintains a condition where it exerts predetermined attracting forces. In this connecting structure, the connecting rods are attracted toward each other and the divided blocks are brought into contact with each other under pressure by tightening an external thread portion of a first tightening member into an internal thread hole of a second tightening member with a tool after the divided blocks are combined so as to match cavities thereof with each other. A connector according to the present invention comprises a first tightening member which is rotatably fitted over an exposed end of a connecting rod of one divided block and a second tightening member which is rotatably fitted over an exposed end of another concrete block.

  • Patent number: 6065263
    Abstract: A connector forces exposed ends of connecting rods buried in divided concrete blocks toward each other. After the divided blocks are combined so as to align respective cavities within the blocks, a tool tightens an external threaded portion of a first tightening member into an internal threaded hole of a second tightening member. The tool thus forces the connecting rods toward each other and brings the divided blocks into contact with each other under pressure.
