JOINT STRUCTURE OF STEEL PIPE REINFORCED CONCRETE COLUMN AND PRESTRESSED BEAM

摘要

PURPOSE: To reduce costs by welding a contact member to a beam connection part of a steel pipe column to pass a PC steel wire of a prestressed beam through the contact member and steel pipe column thereby to tighten the member and column by means of bolts so that a beam of large span having rigidity larger than that of a steel framed beam can be provided. ;CONSTITUTION: A contact member 3 comprising an angle of unequal legs is welded. to an area of a steel pipe column 1 to be joined to a prestressed beam 2. And PC steel wires 4 forming the beam 2 are passed through the column 1 so as to be tightened and stretched by means of nuts 5 thereby to form a joint part. In this case, holes for passage of the wires 4 are formed through the column 1 and hence sectional area of the column is reduced; however, the contact member 3 reinforces the strength of the column. Thus by using the joint part of the column 1 and beam 2, a beam of large span having rigidity larger than that of a steel framed beam can be provided.;COPYRIGHT: (C)1996,JPO
