CONSTRUCTION METHOD FOR PRECAST FLOOR SLAB
To provide a construction method for a precast floor slab that contributes to shortening construction time even when the step includes the installation of the precast floor slab in the steel frame erection cycle.SOLUTION: The steel frame construction step includes a steel frame erection step for erecting the steel frame, and a steel frame joining step for joining steel frame joints 23. A first cutout portion 41 (first hole portion) through which a welding worker 7 (a worker who joins the steel frame) can pass is formed in the precast floor slab 1. The precast floor slab installation step is performed consecutively after the steel frame erection step, and the steel frame joining step is performed after the precast floor slab installation step, in which the welding worker 7 passes through the first cutout portion 41 and moves from above the precast floor slab 1 onto a scaffolding 6 temporarily installed below the precast floor slab 1, and joins the steel frame from below the precast floor slab 1.SELECTED DRAWING: Figure 3
【課題】鉄骨建方サイクル中にプレキャスト床版の設置を含めた工程としても工期短縮に寄与するプレキャスト床版の施工方法を提供する。【解決手段】鉄骨造骨組構築工程では、鉄骨の建方を行う鉄骨建方工程と、鉄骨接合部２３の接合を行う鉄骨接合工程と、を有する。プレキャスト床版１には、溶接作業者７（鉄骨の接合を行う作業者）が通り抜け可能な第１切り欠き部４１（第１孔部）が形成される。プレキャスト床版設置工程は、鉄骨建方工程の後に連続して行われ、鉄骨接合工程は、プレキャスト床版設置工程の後に行われ、溶接作業者７が第１切り欠き部４１を通ってプレキャスト床版１の上方からプレキャスト床版１の下方に仮設された足場６の上に移動し、プレキャスト床版１の下方から鉄骨を接合する。【選択図】図３
