むようにしたことにより問題点を解決したものである。Stepped members for the floor to the landing and from the landing to the floor are manufactured in a factory, and after the stair side formwork, receiving slab formwork, and floor formwork are completed, the formwork for the floor to landing and the landing form are completed. By setting the terrace members from the formwork to the upper floor and slab formwork, reinforcing the landing floor and upper slab, and pouring concrete only on the landing, the framework of the formwork of the terrace members, reinforcement arrangement, and concrete This problem was solved by eliminating complicated work such as pouring, inking, plastering, dismantling and clearing formwork, and by making it possible to finish road closures in one day.

Furthermore, a reinforcing bar (6) is made to protrude horizontally from the landing of the staircase having a plurality of steps (4) to the step member for the floor, and one side reinforcement (8) of the step member (3) is are made to protrude, and a reinforcing bar (8) is made to protrude diagonally from the rear surface of the top stage (4b),
In addition, a dowel bar (9) is made to protrude from one side of the stepped member (5).

Then, weld the embedded metal fittings of the floor (〇〇) and the embedded metal fittings of the step member (3), and place the lower surface of the top step (2a) on the existing formwork for the landing (old), and then Next, hang the floor terrace member (5) from the landing with a crane, place the lower surface of the lowermost step (4a) on the already framed formwork for the landing, and then The lower surface of section (4b) is attached to the formwork (1) for the existing upper floor slab and floor.
Place it on 21.
