<p><P>PROBLEM TO BE SOLVED: To provide a column-beam joint part and reinforcing hardware for the column-beam joint part, capable of making split T-connection for a steel column having a closed cross section rational and simple, by reinforcing the column-beam joint part of the steel column having the closed cross section and a beam made of H-steel by the split T-connection, thereby resulting in shortening of a construction term and reduction of cost of construction. <P>SOLUTION: In this column-beam joint part, ends of the column 1 made of a square-shaped steel pipe, the beam 2 made of H-steel, and an upper part flange 2a and a lower part flange 2b of the beam 2 are composed of joint hardware 3 having a T-shaped cross section to be split T-connected with a beam joint part of the column 1 and a high strength bolt 5. The reinforcing hardware 4 is mounted on the inside of the beam joint part of the column 1 corresponding to the joint hardware 3. The reinforcing hardware 4 is composed of a flange 4a attached additionally to an inner side face part of the beam joint part, a web 4b provided on the flange 4a by protruding substantially horizontally, and reinforcing ribs 4c attached to both of upper and lower sides of the web 4b at substantially right angle to the flange 4a and the web 4b. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
