事より手間がかかり、また仕上げまで多くの工程
を要するため工期が長びくのが難点であるが、他
に次のような問題点がある。(Problems to be Solved by the Invention) The conventional method of constructing reinforced concrete stairs by on-site construction is extremely difficult to construct, takes more time than building the structure, and requires many steps to finish, resulting in a long construction period. This is a difficult point, but there are other problems as well.
階段の上下で壁型枠が分かれるためコンクリー
ト打設圧力により躯体精度が悪くなる。 Because the wall formwork is separated at the top and bottom of the stairs, the concrete placement pressure deteriorates the accuracy of the frame.
階段に隣接する室へ階段歩行音が直接伝わつて
しまう。 The sound of walking on the stairs is transmitted directly to the room adjacent to the stairs.

により緊結するなどして行う。 Stair supports for receiving the precast concrete stairs are buried in the upper and lower floor slabs at the upper and lower ends of the precast concrete stairs. Then, a precast concrete staircase is placed on this staircase bracket and fixed thereto. Fixing is done by bolting the metal fittings embedded in the upper and lower ends of the precast concrete stairs to the stair support fittings.
プレキヤストコンクリート製階段と隣接する壁
との間の隙間には弾性シーリングを施す。 The gap between the precast concrete staircase and the adjacent wall is provided with elastic sealing.
（実施例）
以下本発明を一実施例を示す図面とともに説明
