JOINT AND SHAFT COMBINATION FOR SPACE TRUSS

摘要

PROBLEM TO BE SOLVED: To provide a joint and shaft combination for a space truss at low production cost by reducing the number of screw holes formed in joints for the space truss as much as possible and by reducing the number of components related to pipes as much as possible. SOLUTION: Four blocks composed of an upper cover 1 and an upper body 2, the upper body 2 and a lower body 3, and the lower body 3 and a lower cover 4 or a core having four square pole projections extending radially and 8 brackets combined with the core can be integrally connected together. A shaft is locked between the four blocks or the brackets mutually so as to assemble a simple space truss.
