POSITION ADJUSTMENT DEVICE, AND POSITION ADJUSTMENT METHOD OF UNDERGROUND PILED COLUMN
To provide a position adjustment device for adjusting a building-in position of an underground piled column and a position adjustment method of the underground piled column capable of being used in enlarging a cross section of the underground piled column while utilizing an underground hole having an existing cross section diameter.SOLUTION: A position adjustment device adjusts a building-in position of an underground piled column having a rectangular cross section which is inserted into an underground hole. The position adjustment device comprises: a pressing device positioned between the underground piled column and a hole wall of the underground hole at an external corner portion of the underground piled column and pressing the hole wall; a pressing device support member installed on the underground piled column and supporting the pressing device; and a reactive force receiving member installed on the underground piled column whose front face side is in contact with the pressing device and whose rear face side is in contact with the underground piled column. A column portion of the underground piled column is made of precast reinforced concrete construction. Insert nuts are embedded at a contact position of the reactive force receiving member and the pressing device support member. The reactive force receiving member and the pressing device support member are respectively bolt-fastened via the insert nuts.SELECTED DRAWING: Figure 4
【課題】既往の断面径を有する地中孔を利用しつつ構真柱を大断面化する際に用いることの可能な、構真柱の建込み位置を調整する位置調整装置及び構真柱の位置調整方法を提供する。【解決手段】地中孔に挿入された、矩形断面を有する構真柱の建込み位置を調整する位置調整装置であって、前記構真柱と前記地中孔の孔壁との間であって前記構真柱の出隅部に位置し、該孔壁を押圧する押圧装置と、前記構真柱に設置され、該押圧装置を支持する押圧装置支持部材と、前記構真柱に設置され、表面側が前記押圧装置に当接し、裏面側が前記構真柱に当接する反力受け部材と、を備え 、前記構真柱の柱部分が、プレキャスト鉄筋コンクリート造よりなり、前記反力受け部材と前記押圧装置支持部材の当接位置に、インサートナットが埋設されており、前記反力受け部材と前記押圧装置支持部材がそれぞれ、インサートナットを介してボルト締結されている。【選択図】図４
