EXTERIOR PLATE AND ITS MOUNTING STRUCTURE

PURPOSE:To support an exterior plate certainly against an external force in out-of-plane direction by fixing a certain number of connecting tools for floor slab reinforcing rods to the rear surface of the body of the exterior plate in such an arrangement that the connecting tools are dispersed across the width to the left and right. CONSTITUTION:At the rear surface of the body 2A of an exterior plate, connecting tools 4 are fixed in an arrangement dispersed in the direction across the width to the left and right of the body 2A of exterior plate, wherein the number of such connecting tools 4 is specified as approx. 1/3 or more of the number of floor slab reinforcing rods 3A in the attitude alongside the out-of- plane direction of the floor slab 3 part, which confronts the body 2A of exterior plate in the direction out of the plane of said rear surface of the body 2A. These connecting tools 4 are connected with the rods 3A in the condition that a force in the out-of-plane direction is transmitted between them. The number of connecting tools 4 shall preferably be approx. one half or more of the number of rods 3A, or further favorably be approx. 2/3 or more of the same.
