<P>PROBLEM TO BE SOLVED: To allow stable operations by suppressing deformation and to secure corrosion resistance against rust, in a supporting metal fitting of an H-shaped steel and a concrete slab in a lightweight banking method. <P>SOLUTION: The supporting metal fitting includes a pair of engaging parts to be engaged with a flange of the H-shaped steel slidably in a vertical direction, and deformation and displacement are suppressed by burying the engaging parts in concrete. The engaging part is formed of an U-shaped base plate, a pair of locking pieces in an L shape positioned so as to face both sides of the base plate, and an U-shaped anchor member. Almost all of the supporting metal fitting is buried in the concrete and the corrosion resistance against rust is secured by covering of the concrete and molten zinc plating. <P>COPYRIGHT: (C)2013,JPO&INPIT |
