[0002]

2. Description of the Related Art Conventionally, the upper and lower flanges 17 and 18 of an H-shaped steel mounting beam 16 are joined to the side edges of the upper and lower flanges 12 and 13 of an H-shaped steel beam, with their end faces facing each other. In this case, as shown in FIG.
On the side edges 14 and 15 of the upper and lower flanges 12 and 13 and the side surface of the web 39, the end side surfaces of the upper and lower flanges 41 and 42 and the end side surface of the web 43 of the H-shaped steel take-out beam 40 are welded,
The splice plate 45 is superposed on the flanges 17, 18, 41, 42 and the webs 43, 44 of the projecting take-out beam 40 and the attaching beam 16 and bolted,
A method of joining the take-out beam 40 and the attachment beam 16 via the splice plate 45 is adopted.

As another method, as shown in FIG. 21, a joint plate 46 is welded at a right angle to the web 39 of the through beam 11, and the joint plate 46 protruding from the through beam 11 is attached to the web of the attaching beam 16. 44 is bolted and joined, and the flanges 1 of the through beam 11 and the attachment beam 16 are connected.

SUMMARY OF THE INVENTION Therefore, according to the present invention, the attachment beam 16 can be joined to the through beam 11 without welding the take-out beam 40 and the joint plate 46, and by doing so, the through beam 11 can be formed.
In addition to reducing costs, standardize the frame system of steel structures to transport through beams 11, stock, and
The purpose is to rationalize construction work.
