CONSTRUCTION METHOD OF RAFT FOUNDATION AND RAFT FOUNDATION STRUCTURE
To provide a construction method of a raft foundation and a raft foundation structure allowing productivity and in-site workability to be improved, construction cost to be reduced, and construction period to be reduced through securing connection strength between an inner foundation and a bottom base, and standardizing the inner foundation.SOLUTION: A construction method of a raft foundation provided at least with a concrete bottom base 10 and an outer foundation and an inner foundation comprises: a first step of arranging a plurality of precast concrete materials 40 without connecting each other, the precast concrete materials 40 composing the inner foundation, which is provided with a concrete body 41, leg parts 42 extending downward from the concrete body, and a plurality of vertical bars 43 of which one end are buried in the concrete body and the other end extend downward from the concrete body and bend; a second step of binding the vertical bars 43 and bottom base bars 11; and a third step of integrating the bottom base and the inner foundation through filling concrete in a lower part of the concrete body 41 to such an extent the lower part is fully filled.SELECTED DRAWING: Figure 2
【課題】内部基礎と底盤との接合強度を確保し、内部基礎を規格化することで生産性向上、現場での施工性向上、施工コストの抑制、工期短縮を実現できるべた基礎の施工方法及びべた基礎構造を提供する。【解決手段】コンクリート製の底盤１０、外部基礎及び内部基礎を少なくとも備えるべた基礎の施工方法において、内部基礎を構成するプレキャストコンクリート部材４０が、コンクリート本体部４１と、その下面から下方にのびる脚部４２と、一端がコンクリート本体部の内部に埋設されており、他端がコンクリート本体部の下面から下方にのびて屈曲する複数の縦筋４３とを備えており、複数のプレキャストコンクリート部材４０を相互に連結せずに配置する第１工程と、縦筋４３と底盤筋１１とを結束する第２工程と、コンクリート本体部４１の下部が埋まる程度にコンクリートを打設することで底盤と内部基礎とを一体化する第３工程を備える。【選択図】図２
