CONSTRUCTION METHOD OF BUILDING FOUNDATION, AND PARTITION FRAME

To provide a construction method of a building foundation which can eliminate the need to install leveling concrete between a pile head of a pile-like ground reinforcement body driven into a ground and a bottom face side of a building foundation, and to provide a partition frame capable of being used in the construction method of a building foundation.SOLUTION: A construction method of a building foundation includes the steps of: exposing a pile head 21 of a pile-like ground reinforcement body 2 driven into a ground; disposing a partition frame 100 forming a pile head space 31 for concrete installation at an upper side of the pile head 21; laying crushed stone 4 at a peripheral side of the partition frame 100 and fastening; providing a formwork 5 of a building foundation in a region including the pile head space 31; and installing concrete into the formwork 5 manufacturing the building foundation and into the pile head space 31.SELECTED DRAWING: Figure 1 【課題】地盤に打ち込んだ杭状地盤補強体の杭頭と建物基礎の底面側との間に捨てコンクリートを打設することを不要にできる建物基礎の施工方法、並びにこの建物基礎の施工方法において用いることができる仕切り枠を提供する。【解決手段】建物基礎の施工方法は、地盤に打ち込まれた杭状地盤補強体２の杭頭２１を露呈させる工程と、杭頭２１の上側にコンクリート打設用の杭頭上空間３１を形成する仕切り枠１００を配置する工程と、仕切り枠１００の周囲側に砕石４を敷いて締め固める工程と、杭頭上空間３１を含む領域に建物基礎の型枠５を設ける工程と、建物基礎を作製する型枠５内および杭頭上空間３１内にコンクリートを打設する工程と、を含む。【選択図】図１
