REINFORCEMENT STRUCTURE OF COLUMN TYPE FOUNDATION FOR EXPOSURE TYPE COLUMN BASE
To provide a reinforcement structure of column type foundation for an exposure type column base which prevents an increase in size of column type foundation, secures excellent resistance action to deformation of an anchor bolt, and can appropriately suppress cone-type destruction of a column type concrete body.SOLUTION: Column type foundation 1 for an exposure type column base has a plurality of rise reinforcements 2 arranged in annular arrangement in a vertical height direction, a plurality of hoop reinforcements 4 which is annularly formed so as to surround arranged in multi-stages in the vertical height direction of the rise reinforcements, and a plurality of anchor bolts 5 that are positioned inward the rise reinforcements and are arranged in annular arrangement embedded in a column type concrete body 3 having a flat cross-sectional square shape; and an exposure type column base part 6 is installed and fixed, in which a plurality of reinforcement plates 10 are provided between the anchor bolts and an outer surface 3a of the column type concrete body so as to inscribe the plurality of hoop reinforcements from the hoop reinforcement 4A of the uppermost stage to the hoop reinforcement of the lower part and correspond to one anchor bolt one by one.SELECTED DRAWING: Figure 1
【課題】柱型基礎を大型化することなく、アンカーボルトの変形に対し優れた抵抗作用を確保して、柱型コンクリート体のコーン状破壊を適切に抑制することが可能な露出型柱脚用柱型基礎の補強構造を提供する。【解決手段】平断面正方形状の柱型コンクリート体３内に、上下高さ方向に沿って、環状の配列で複数配筋される立ち上がり筋２と、立ち上がり筋の外回りを包囲する環状に形成され、立ち上がり筋の上下高さ方向に多段に配筋される複数のフープ筋４と、立ち上がり筋よりも内方に位置させて環状の配列で複数配設されるアンカーボルト５とが埋設され、露出型柱脚部６が設置固定される露出型柱脚用柱型基礎１であって、アンカーボルトと柱型コンクリート体の外面３ａとの間に、最上段のフープ筋４Ａから下方のフープ筋にわたり複数のフープ筋に内接させて、かつアンカーボルト１本１本に１対１で対応させて、複数の補強プレート１０を設けた。【選択図】図１
