<P>PROBLEM TO BE SOLVED: To provide a lightweight metal substrate that can shorten a necessary distance of a finished surface to a minimum while securing a thickness of a wet fire-resistant coating material and can be attached without dividing a fire-resistant coating plate into pieces, the lightweight metal substrate being easy to process and simply attached. <P>SOLUTION: The lightweight metal substrate comprises an L-sectioned corner angle member attached in parallel with a corner part of an iron column and/or an iron beam to which the fire-resistant coating material and fire-resistant coating plate are attached, and an erection member comprising a bridge part constructed orthogonally between corner angle members and sectioned substantially in a flat plate shape, and a fixation part gripping the corner angle members at both ends of the bridge part. The fixation part of the erection member includes a fixation part body surrounding the outside of an angle surface of the corner angle member and a gripper bent at both edge parts or one edge part of the fixation part body to grip an angle collar part as a side edge of the angle surface of the corner angle member, the bridge part being provided connecting with the fixation part body. <P>COPYRIGHT: (C)2013,JPO&INPIT |
