Title:
CONCRETE BLOCK COUPLING STRUCTURAL BODY AND COUPLER USED IN THE SAME
Document Type and Number:
Japanese Patent JP3544917
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a concrete block coupling structural body capable of coupling concrete blocks mutually and firmly in a proper pressure contact condition.
SOLUTION: A second tightening member 62 arranged on a coupling rod 30 of a divided block DB1 on one side among a first tightening member 61 arranged on a coupling rod 30 of the other divided block DB2 and the second tightening member 62 is turned to tighten a female screw part 62b of the second tightening member 62 into a male screw part 61c of the first tightening member 61 to give a force in the direction of mutual draws near to mutually opposing coupling rods 30, 30 and maintain a condition in which a predetermined attraction force is given so that the divided blocks DB1, DB2 are brought into pressure-contact and are mutually and firmly coupled.
