摘要

Structural lattice element for three-dimensional frames, comprising tubular elements of girders and global connectors, each of said connectors possessing a series of threaded holes in the connector, each of the tubular elements of the frame having an integral end cap each of its elements. Opposite ends, said end cap possessing a central hole coaxial with said tubular, having a connecting bolt of an expanded head disposed within an internal space of said gimbal element and extending a threaded shank coaxially with respect to said jumper element protruding towards out through said central hole, said threaded shank being able to be coupled with a polygonal sleeve mounted on said shank so as to be slidable axially back and forth within a predetermined length but not rotatable with respect to said shank, characterized for the c arranging a series of holes receiving plugs in a front end wall of said end cap, so that a mouth of at least one of said plug receiving orifices is completely exposed when a rear end wall of said radially and angularly separated each constituted any of said threaded holes of the connector, sleeve is in intimate contact with said front end wall of the said cap, and a plug is inserted into said receiving hole whose mouth is completely exposed a part of said plug in contact with a flat side wall of said sleeve.
