イド式仮階段。 The front parts of the left and right pillars of a lower ladder rung are formed by fixing the front ends of the left and right sides of a number of treads at a predetermined pitch to the outer wall surface of the groove of the left and right pillars, which are facing each other at a distance. At the top of the rising piece, the rear ends of the left and right sides of the numerous treads are placed on the outer wall surface of the groove of the left and right pillars facing each other at intervals, so that the rear ends of the left and right sides of the many treads are aligned at the same pitch as the pitch of each tread of the lower ladder rung. The lower parts of the rear rising pieces of the left and right pillars of the upper ladder rung, which are fixed and provided with hooks at the front ends of the topmost treads, are overlapped, and the upper ends of the left and right pillars of the lower ladder rung are attached to the upper ladder rung. A sliding temporary staircase is provided in which slide guides are provided at the lower ends of the left and right pillars, respectively, and the overlapped portions of the front rising piece of the lower ladder rung and the rear rising piece of the upper ladder rung are screwed together.
