JOINT DEVICE BETWEEN MEMBERS FOR CONSTRUCTION

摘要

PROBLEM TO BE SOLVED: To provide a joint device between members excellent in execution workability having high rigidity and strength and generating small displacement and residual displacement relating to extracting force. SOLUTION: A protruded type joint 1 provided in one of the fellow members intended to be connected is fitted to a recessed part of a hollow type joint 2 provided in the other to make connection. The hollow type joint 2 has an outer frame unit 2a having a tapered hole, a wedge unit 3 set up in this tapered hole, and a coil spring 4 energizing the wedge unit 3 toward an insertion port side inserted with the protruded type joint 1. A tapered angle of the wedge unit 3 corresponding to the tapered hole of the outer frame unit 2a is set to 10 degrees or more. A protruded part 1a of the protruded type joint 1 pressed into the hollow type joint 2 is tightened from an external periphery by the wedge unit 3 energized by the coil spring 3, to resist against an extracting load.
