PCT No. PCT/JP87/00137 Sec. 371 Date Mar. 29, 1988 Sec. 102(e) Date Mar. 29, 1988 PCT Filed Mar. 4, 1987 PCT Pub. No. WO88/01323 PCT Pub. Date Feb. 25, 1988.A device for joining elongate structure members to connector nodes includes a bolt having oppositely threaded ends for threaded engagement with a nut at one end and a connector node at the other end. Between its threaded ends the bolt has a cylindrical portion and a torque transmitting portion. An externally threaded bolt-support member engageable with internal threads at the end of the structure member slidingly receives the cylindrical portion of the bolt while a sleeve with an internal aperture non-rotatably but slidingly receives the torque-transmitting portion of the bolt. In use, the nut prevents the bolt from pulling out of the bolt-support member while external torque applied to the sleeve tightens the structure member to the connector node. An elastic sealing member around the bolt is squeezed between the connector node and the torque-transmitting portion of the bolt and this may be supplemented by sealing material applied at the interface between the sleeve and the structure member end. The critical components of the combination, especially the threads thereof, are thus protected against ambient corrosion and a strong, durable, easily made connection is provided for highly loaded structures. |
