BOTTOM EXPANSION MEMBER, STEEL TOWER FOUNDATION STRUCTURE, AND CONSTRUCTION METHOD OF STEEL TOWER BASE
To provide a bottom expansion member capable of suppressing construction work of a base construction from getting complicated while ensuring resistance against a pull-out load of the base, a steel tower foundation structure, and a construction method of steel tower base.SOLUTION: A bottom expansion member 40 has a plurality of main bodies 80 of precast concrete, which can be placed inside an excavation hole 26A drilled in a ground 26 along a circumferential direction of a floor plate 30 that retains a leg material 24 constituting a part of steel legs 20 of a steel tower 10. The bottom of excavation hole 26A is configured so that a part thereof can be inserted into a radially expanded bottom part 26A2 of excavation hole 26A, and so that a load can be transmitted to an outer peripheral surface 30B of the floor plate 30.SELECTED DRAWING: Figure 1
【課題】基礎の引き抜き荷重に対する抵抗を確保しつつ、基礎の構築作業が煩雑になることを抑制することができる拡底部材、鉄塔基礎構造及び鉄塔基礎の構築方法を提供する。【解決手段】拡底部材４０は、地盤２６に掘削された掘削穴２６Ａの内側に配置されて鉄塔１０の鉄骨脚部２０の一部を構成する脚材２４を保持する床板３０の周方向に沿って複数配置可能とされ、掘削穴２６Ａの下部が掘削穴２６Ａの径方向に拡大された拡底部２６Ａ２に一部が挿入可能とされると共に、床板３０の外周面部３０Ｂと荷重の伝達が可能とされたプレキャストコンクリート製の本体部８０を有している。【選択図】図１
