HIGH STRENGTH BOLT CONNECTION STRUCTURE OF STEEL PIPE COLUMN FILLED WITH CONCRETE AND H-SHAPED CROSS SECTIONAL BEAM, AND ITS HIGH STRENGTH ANCHOR BOLT

摘要

PROBLEM TO BE SOLVED: To provide a connection structure of a square or circular steel pipe column (CFT column) filled with concrete by use of a joint metallic fitting and a high strength bolt, and an H-shaped sectional beam, and a head fastening high strength bolt realizing the connection structure, enabling cost reduction and improvement of joint capacity and an H-shaped sectional beam. ;SOLUTION: A nut to which an anchor plate having a female screw is roughly connected in advance, is fixed to the inside of a steel pipe column and a head fastening high strength bolt which can form an anchor part at the front end side, is inserted from the outer face of the jointing metallic fitting brought into contact with the outer face of the steel pipe column to the bolt hole, and the male screw is fittingly connected to a nut fixed to the inner side of the steel pipe column to form an anchor part at the front end side and embedded in the concrete filled into the steel pipe column and solidified.;COPYRIGHT: (C)2004,JPO
