JOINING DEVICE FOR REINFORCED CONCRETE COLUMN AND STEEL-FRAME BEAM, AND JOINT STRUCTURE OF REINFORCED CONCRETE COLUMN AND STEEL-FRAME BEAM

摘要

PROBLEM TO BE SOLVED: To provide a joining device for a reinforced concrete column and a steel-frame beam and a joint structure of a reinforced concrete column and a steel-frame beam which can provide a sufficient joining performance and can easily and accurately join the steel-frame beam to the reinforced concrete column without requiring high construction accuracy.;SOLUTION: This joining device for a reinforced concrete column and a steel-frame beam includes a joint metal 6 which is disposed inside hoop reinforcements 3 and buried in a reinforced concrete column 1, female screw members 12 the base ends 12a of which are joined to the joint metal and which are buried in the reinforced concrete column while avoiding the hoop reinforcements to open screw holes at the front ends 12c thereof to the side surface of the reinforced concrete column, an end plate which has loose holes and is installed at the end of a steel-frame beam facing the reinforced concrete column to form a grout filling space between reinforced itself and the concrete column, and joining screw members which are inserted into the loose holes to join the end plate and the female screw member, at one end of which a first screw screwed with the female screw member is formed, at the other end of which a second screw tightened with the end plate is formed, and which has a shaft body formed at a position through which the side surface of the reinforced concrete column extends between the first screw and the second screw.;COPYRIGHT: (C)2011,JPO&INPIT
