STEEL TOWER FOUNDATION STRUCTURE
To provide a steel tower foundation structure which can prevent a load from an upper side in a height direction of a steel tower from affecting a foundation part of the steel tower, while facilitating transport of members constituting the foundation part of the steel tower.SOLUTION: A steel tower 10 includes: leg materials 24; a precast concrete upper side floor plate block 46 which constitutes a portion of an upper side in a height direction in a floor plate 30 which is arranged on the radially outside of a spiral reinforcement 32, and in which adjacent ones are connected; a precast concrete lower side floor plate block 48 which constitutes a portion of a lower side in the height direction in the floor plate 30; a lower side reinforcement 56 including a lower side vertical reinforcement 56A which is arranged on the radially inside of the spiral reinforcement 32, and which extends in the height direction, and a lower side horizontal reinforcement 56B a part of which is embedded in the lower side floor plate block 48; and a steel hoop reinforcement 34 which has an annular shape surrounding the lower side vertical reinforcement 56A when viewed from the height direction, and which is bonded to the lower side horizontal reinforcement 56B in a state of being supported by the lower side horizontal reinforcement 56B from the lower side in the height direction.SELECTED DRAWING: Figure 1
【課題】鉄塔の基礎部を構成する部材の運搬を容易なものとしつつ、鉄塔の高さ方向上側からの荷重が鉄塔の基礎部に影響を及ぼすことを抑制することができる鉄塔基礎構造を提供する。【解決手段】鉄塔１０は、脚材２４と、螺旋筋３２の径方向外側に配置された床板３０における高さ方向上側の部分を構成し、隣接する同士が連結されたプレキャストコンクリート製の上側床板ブロック４６と、床板３０における高さ方向下側の部分を構成するプレキャストコンクリート製の下側床板ブロック４８と、螺旋筋３２の径方向内側に配置されると共に高さ方向に延在する下側縦筋５６Ａと、下側床板ブロック４８に一部が埋め込まれた下側横筋５６Ｂと、を備えた下側補強筋５６と、高さ方向から見て下側縦筋５６Ａを囲む円環状とされ、下側横筋５６Ｂに高さ方向下側から支持された状態で下側横筋５６Ｂに接合された鋼製のフープ筋３４とを有している。【選択図】図１
