PCT No. PCT/JP90/00395 Sec. 371 Date Oct. 30, 1990 Sec. 102(e) Date Oct. 30, 1990 PCT Filed Mar. 26, 1990 PCT Pub. No. WO90/11416 PCT Pub. Date Oct. 4, 1990.A device for joining an elongate structural member having a hollow end to a connector node includes a cover for the hollow end and an elongate bolt extending a threaded end therethrough for engaging with the node. A portion of the bolt between the threaded distal end and a bolt head at the opposite end has the form of a square cross-sectioned boss which has an external thread cut into corner portions thereof such that the square boss can be threaded through an internally threaded aperture in the cover, this internally threaded aperture being smaller than the bolt head. A sleeve having a length longer than the square boss has a square through-aperture sized to slidingly fit around the square boss. During use of the device, the cover is welded to an end of the elongate structural member, the sleeve is slidingly fitted around the square boss and a threaded distal end of the bolt is threaded to a matchingly sized threaded aperture in a node and the bolt is tightened thereto by the application of an external torque provided to an outside surface of the sleeve. |
