One-side volt/bolt use beam-column junction structure

摘要

PURPOSE: To secure the durability and rigidity of a connection part of a column and a beam with the simple structure, and to easily perform the connecting work from outside of a steel pipe colunm, which has the closed cross section, without performing the welding at a construction field. ;CONSTITUTION: A reinforcing member 21 is provided in the inner surface of a beam connection part of a steel pipe column 20. The end of a steel frame beam 22 is connected to the steel pipe column 20 by one-side bolts 1, which are respectively passed through a connecting fitting 23, the pipe wall of the steel pipe colunm 20 and the reinforcing member 21, through the connecting fitting 23 provided in the end of the steel frame beam 22. As the one-side bolt 1, a bolt, of which lead-in axial force is applied as the fastening force, is used. As the steel pipe column 20, a square steel pipe column or a round steel pipe column is used. As the steel frame beam 22, a H-type steel or the like is used. As the reinforcing member 21, a plate to be overlapped with the inner surface of the steel pipe column 20, a diaphragm, or a rib connected along the vertical direction is used.;COPYRIGHT: (C)1996,JPO
