SAFETY CONSTRUCTION STAIR
PROBLEM TO BE SOLVED: To provide a safety construction stair in which the rear ends of a base tread can be supported from a lower side.SOLUTION: A safety construction stair of the present invention includes multiple base treads 21 disposed in the diagonal direction at intervals. An upper end of a riser 3 disposed between adjacent base treads 21 is disposed in response to a front lower surface of the base treads 21 of the upper side. Also, a decoration tread 25 is stuck to the upper surface of the base tread 21 and becomes a finished state with respect to a temporary construction state where the front surface lower end of the riser 3 is disposed in response to the rear end of the base tread 21 of the lower side. In the front surface lower end of the riser 3, a tread insertion groove 30 is formed in response to the rear end of the base tread 21, and is disposed in the state where the rear end of the base tread 21 is inserted in the tread insertion groove 30.SELECTED DRAWING: Figure 7
【課題】下地段板の後端を下側から支持できる安全施工階段を提供する。【解決手段】本発明は、斜め方向に間隔をおいて配置される複数の下地段板21を備え、隣り合う下地段板21間に配置されるけこみ板3の上端が上側の下地段板21の前部下面に対応して配置されるとともに、当該けこみ板3の前面下端部が下側の下地段板21の後端に対応して配置された仮設状態に対し、下地段板21の上面に化粧段板25が貼り付けられて仕上げ状態となる安全施工階段を対象とする。けこみ板3の前面下端部に、下地段板21の後端に対応して段板挿入溝30が形成されるとともに、その段板挿入溝30に下地段板21の後端が挿入された状態に配置されている。【選択図】図7
