び割れ防止構造。[Scope of Claim for Utility Model Registration] (1) In the structure of earthen concrete where a base layer is formed on the top surface of the soil, a sheet material is spread on the top surface, and a concrete layer is poured, the sheet material has water retention properties. An earthen floor concrete containing a porous synthetic resin fibrous material, which absorbs excess water during concrete placement and also prevents water from penetrating from the soil into the concrete. Anti-crack structure. (2) The sheet material is formed in multiple layers by a water-permeable synthetic resin sheet made of nonwoven fabric, a porous water-absorbing material made of polymeric synthetic resin, and a synthetic resin sheet. A crack-prevention structure for concrete with an earthen floor.
