JOINT STRUCTURE OF CIRCULAR STEEL TUBE TRUSS CONSTRUCTION

摘要

The present invention relates to a joint structure in which a chord and a brace are joined in a structure of truss construction configured of a circular steel tube, wherein the chord and the brace are formed of the circular steel tube. Moreover, an end portion of the brace is joined to the chord via a reinforcement support, and the reinforcement support is attached to an outer surface of the chord. The joint structure comprises: a longitudinal reinforcement bar installed in the longitudinal direction of the chord; a transverse reinforcement bar vertically installed on both sides of the longitudinal reinforcement bar; and a brace support installed on an upper surface of the longitudinal reinforcement bar and the transverse reinforcement bar. The brace support is formed with a flat surface parallel in the longitudinal direction of the chord, and an end portion of the brace is joined to the flat surface of the brace support.
