HIGH STRENGTH BOLT JOINT STRUCTURE OF CIRCULAR STEEL PIPE COLUMN AND H-SHAPED BEAM AND CONNECTION HARDWARE

摘要

PROBLEM TO BE SOLVED: To provide a high strength bolt joint structure of a circular steel pipe column using special shaped connection hardware capable of stably ensuring joint performance (rigidity and proof stress) and alleviating a burden on the cost and an H-shaped beam and the special shaped construction hardware used for the joint structure.;SOLUTION: The connection hardware connected to both the top and bottom of the circular steel pipe column at a predetermined interval are formed of a pair of right and left deformed T-formed sections or deformed L-formed sections having inclined flanges arranged in a line in parallel with the H-shaped beam, the flanges of a pair of right and left deformed T-formed sections or deformed L-formed sections are abutted on the circular steel pipe column, the circular steel pipe column and the flanges of a pair of deformed T-formed sections or deformed L-formed sections are clamped/connected with the high strength bolt inserted so as to turn to the center of the circular steel pipe column in the abutment part or in a neighboring area of the abutment part, both the top and bottom flanges of the H-shaped beam are connected to webs of a pair of right and left deformed T-formed sections with a high strength bolt.;COPYRIGHT: (C)2004,JPO
