REINFORCEMENT DEVICE FOR CYLINDRICAL TYPE PRECAST CONCRETE MEMBER AND CONCRETE FLOATING STRUCTURE IN FLOATING TYPE WIND POWER GENERATION FACILITY ON OCEAN USING THE SAME

To provide a precast cylindrical body reinforcement device with advantages such as being capable of evenly reinforced in all directions in a periphery and at least being detachable after installation.SOLUTION: A structure has tension cables 30, 30... expanding along an inscription regular polygonal line inside a precast cylindrical body 15. The tension cables 30 are laid so as to introduce tensile force between adjacent anchorage metal fittings 31, 31 by fixing the adjacent metal fittings 31, 31 in respective vertex positions in the inscription regular polygonal lines. In addition, a plurality of reinforcement devices 2 stretching the tension cables 30 along the inscription regular polygonal line are provided in pairs at prescribed intervals in a direction of axial center of the precast cylindrical body 15 along the inscription regular polygonal line.SELECTED DRAWING: Figure 6 【課題】全周方向に亘って均等に補強できること、及び少なくとも設置後に取り外しが可能であるなどの利点を備えたプレキャスト筒状体の補強装置を提供する。【解決手段】プレキャスト筒状体１５の内側において、内接する正多角形状線に沿って緊張ケーブル３０、３０...が張設されている構造とする。内接する正多角形状線の各頂点位置に定着金具３１、３１...を固定し、隣接する定着金具３１、３１間に緊張力を導入可能に緊張ケーブル３０を架け渡す。また、内接する正多角形状線に沿って緊張ケーブル３０を張設した補強装置２を一組としてプレキャスト筒状体１５の軸芯方向に所定の間隔で複数設けるようにする。【選択図】図６
