FLOOR CONSTRUCTION METHOD

To improve workability when fire-resistively covering an upper surface of a plurality of wooden floor slabs at a construction site.SOLUTION: A floor construction method includes: a floor member installation step of installing a plurality of floor members 20 each of which includes a wooden floor slab 22, and a first cement-based fire resistive covering material 50 for covering an upper surface 22U2 of the wooden floor slab 22 at least leaving an end part 22E in such a manner that end parts 22E are adjacent to each other; and a fire resistive covering step of pouring a second cement-based fire resistive covering material 60 between the adjacent first cement-based fire resistive covering materials 50, and for fire-resistively covering upper surfaces 22U1 of the adjacent end parts 22E by the second cement-based fire resistive covering material 60.SELECTED DRAWING: Figure 2 【課題】本発明は、現場において、複数の木質床版の上面を耐火被覆する際の施工性を向上することを目的とする。【解決手段】床施工方法は、木質床版２２と、少なくとも端部２２Ｅを残して木質床版２２の上面２２Ｕ２を被覆する第一セメント系耐火被覆材５０と、を有する床部材２０を、端部２２Ｅ同士を隣り合わせて複数設置する床部材設置工程と、隣り合う第一セメント系耐火被覆材５０の間に第二セメント系耐火被覆材６０を流し、隣り合う端部２２Ｅ同士の上面２２Ｕ１を第二セメント系耐火被覆材６０によって耐火被覆する耐火被覆工程と、を有する。【選択図】図２
