PROBLEM TO BE SOLVED: To obtain superlative architectural designability by applying a finish material which was continuously formed in one united body for at least two steps of treads and risers, and giving nonslip irregular finish or inlaying board members of different materials to the finish material of the tread. SOLUTION: One side surface of a stair 1 made of a tread 11 and a riser is made of a wooden handrail wall 2, other side surface is made of a partition wall 3, and a groove-shaped recessed and projected portion 4c is provided at the tip portion of the tread 11, and a foamed resin 4d is applied to the rear surface. Moreover, a base portion of a clip 5 is embedded in the foamed resin 4d on the bottom surface, a tip 5a of the clip 5 is fitted to a transparent hole of the tread 11 and fixed. Also, a handrail 6 is attached to the sloped upper surface of the handrail wall 2. Next, the surface 6a of the handrail 6 is made of vinyl chloride, a pipe portion at the top and a hollow portion at the base is filled up with foamed urethane 6b, and a slit is formed for attaching a mounting fittings 6c in the longitudinal direction. Thus, the stair having safety and excellent architectural desinability can be obtained. |
