Abstract

PURPOSE:To prevent oscillation of a stair by fixing the outdoor side of a stair provided outside a building to a side beam through a fastener and providing a handrail wall, the lower end of which is supported on a foundation. CONSTITUTION:A stair 2 provided with a plurality of footboards 6 and treadboards 7 is fixed between side beams 5 comprising channel steel through fasteners 8. And the upper end and lower end of the side beam 5 are supported by a column 15 erected on a foundation 11 and a handrail wall 4 is fixed to the side beam 5 on the outdoor side through the fastener 8. Further, base materials 10 comprising channel steel are provided at the upper end and lower end of the handrail wall 4 and the lower end of the wall 4 is placed on a concrete block 11a of the foundation 11 and fixed to an anchor bolt 12. Consequently, the handrail wall can be prevented from falling down and safety can be improved.

Since the load of the handrail wall 54 is borne by the above, the load is limited and only the lightweight handrail wall 54 can be attached. Further, since the handrail wall 54 is supported by the side girders 51 in this manner, the handrail wall 54 vibrates along with the stairs 50 and does not serve as a shake preventing means. Therefore, it is necessary to stretch the brace in a cross shape between the both side girders 51 at the bottom of the stairs 50 as a measure for preventing shake.
