摘要： PURPOSE: To construct a high quality stairs without skillful techniques, in the site works. CONSTITUTION: A stairs 2 is constituted of a plurality of PC stairs provided with a lower stage divided-landing and an upper stage divided-landing formed as a unit in the lower and upper stages of a stepping floor, and anchor rods on the stepping floor, protruded from the connection part of the floor. In the bearing wall 1, omnia-wall boards 3, 3 in which truss reinforcements and external reinforcements connected thereto are exposed at one face, make a hollow space between wall boards while oppositely arranging mutual truss reinforcements and oppositely position. The connection parts of PC stairs continuing at every specified floor are inserted in a specified position of these omnia- wall boards 3, 3 and notches extending the anchor reinforcements of the floor to the hollow space, are provided. Cast-in-place concrete is placed into the hollow space and the anchor reinforcements are fixed.

摘要： PURPOSE:To construct good-quality stairs without requiring skill in work at a job site. CONSTITUTION:Stairs parts 2 are constituted on both surfaces of a bearing wall 1 so as to spring out in a cantilever shape by sandwiching the bearing wall 1 between them; Cast-in-place concrete wall parts 8 are arranged so as to continue with both left and right end surfaces of a PC bearing wall 4 to constitute a main body of the bearing wall 1. The cast-in-place concrete wall parts 8 are integrally formed with the PC bearing wall 4 by burying anchor reinforcements 7. The PC stairs parts 2 are composed of a PC member. Anchor reinforcements 9 are protrusively arranged toward the cast-in-place concrete wall parts 8 from side surfaces of the uppermost stage part and the lowest stage part in the PC stairs parts 2. The respective anchor reinforcements 9 are buried in the opposed cast-in-place concrete wall parts 8, and are integrally formed with the cast-in-place concrete wall parts 8.
