<p>PROBLEM TO BE SOLVED: To easily execute stairs using a precast concrete member without requiring a large-scale temporary facility or the like. SOLUTION: A wall-floor structure 10A is formed integrally of precast concrete in which a bearing wall section 11, size in the height direction of which is one over an approximately integral section of the stair height of a building, and a landing floor section 12 installed so as to cross one vertical end section of the bearing wall section 11 at right angles are continued. A plurality of the wall-floor structures 10A are arranged so that the landing floor sections 12 are directed alternately to the reverse sides while being positioned in each floor slab of the building or the intermediate height of the floor slabs, the bearing wall sections 11 are joined mutually in the vertical direction, and a stair body 20 composed of precast concrete is built and joined among each landing floor section 12.</p> |
