んで対向する。A substantially L-shaped connecting body 8 composed of an adhesive piece 9 to the child beam 7 and an attachment piece 10 to the parent beam 1 is bonded to both ends of the child beam 7 by welding or the like. The attachment piece 10 has a flat plate shape, and has a larger area than the mounting surface 6 of the parent girder 1 and contacts the mounting surface 6. At the center of the mounting piece 10, a screw hole 10a in which a female screw is cut is provided. Protrusions 10b, 10b are continuously provided on both sides of the attachment piece 10. The protruding piece 10b has a length corresponding to the protruding length of the mounting surface 6 of the main girder 1. That is, when the mounting piece 10 is brought into contact with the mounting surface 6 of the main girder 1,
The protruding piece 10b is in contact with the concave surface 3b of the main girder 1 and faces the mounting surface 6 therebetween.
