SQUARE STEEL TUBE STEEL-FRAME TRUSS JOINT FOR SECURING STRUCTURAL STRENGTH AND EXECUTING ASSEMBLING AND DISMANTLING EASILY BY USING HIGH TENSION STEEL BAR

摘要

PURPOSE: A square steel tube steel-frame truss joint is provided to assemble and dismantle an upper chord and a lower chord with/from a web to bear the roof load by securing structural strength and stiffness of a joint, to simplify construction work and to heighten safety and economical efficiency with excellent durability. CONSTITUTION: The square steel tube steel-frame truss joint comprises a high tension steel bar(10), a pin plate(11), upper and lower chord square steel tubes(12,12a), a diagonal square steel tube, and a post square steel tube. The square steel tube truss joint contains many webs which are formed by a fixed joint and a pin joint, installed between upper chord square steel tubes(12,12a) arranged to be inclined longitudinally and lower chord square steel tubes arranged horizontally, and composed of a high tension steel bar(10) and a spade end(10a).
