PURPOSE:To enhance safety by forming a support metal fitting composed of a base part and a leg part, joining the base part so that the leg part can rotate to the base part, and supporting a slope plate by putting the support metal fitting in an indoor-outdoor step difference part. CONSTITUTION:A support metal fitting 1 is formed by joining a metallic cross- sectional U-shaped base part 2 and a leg part 3, and the base part 2 of the support metal fitting 1 is applied to the reverse both ends of a slope plate, and is fixed to the slope plate by nails 15. The leg part 3 of the support metal fitting 1 is rotated, and a height of the support metal fitting 1 is adjusted to a step difference height, and after the leg part 3 is fixed by fastening a thumbscrew 13, it is extended over a place having a step difference. Therefore, stumbling at traveling time or impact at passing time by a wheelchair or the like can be perfectly prevented. |
