SHAPE HOLDING MECHANISM, INSTALLATION DEVICE FOR STRAND REINFORCEMENT CAGE AND INSTALLATION METHOD FOR STRAND REINFORCEMENT CAGE
To provide a shape holding mechanism, an installation device for a strand reinforcement cage and an installation method for the strand reinforcement cage capable of holding a shape of the strand reinforcement cage to prevent its deformation when raising it up from a horizontal state to a vertical state.SOLUTION: A method uses a shape holding mechanism 3 comprising: an insertion frame 5 configured to secure a beam member 5b on a frame body 5a, a movable member 7a connected to the frame body 5a, and an end part holding mechanism 31 connected to the beam member 5b; and an installation device 1 provided with a column 9 secured on the beam member 5b and a cylinder 13 to raise up the column 9. Then, inserting the frame body 5a arranged horizontally to a strand reinforcement cage 27 to move the movable member 7a to a direction where a distance from the frame body 5a becomes larger, expands and deploys the strand reinforcement cage 27 in a pile hole 33 through raising the frame body 5a with the cylinder 13 in a state of holding a cross-sectional shape of the strand reinforcement cage 27.SELECTED DRAWING: Figure 3
【課題】水平な状態から垂直な状態に立て起こす際にストランド鉄筋籠の形状を保持して変形を防止できる形状保持機構、ストランド鉄筋籠の建て込み装置及びストランド鉄筋籠の建て込み方法を提供する。【解決手段】フレーム本体５ａに梁部材５ｂが固定された内挿フレーム５と、フレーム本体５ａに連結された可動部材７ａと、梁部材５ｂに連結された端部支持機構３１とからなる形状保持機構３と、梁部材５ｂに固定された支柱９と、支柱９を立て起こすシリンダ１３とを具備する建て込み装置１を用いる。そして、水平に配置されたフレーム本体５ａをストランド鉄筋籠２７に内挿し、可動部材７ａをフレーム本体５ａからの距離が大きくなる方向に移動させることによってストランド鉄筋籠２７の断面形状を保持した状態で、シリンダ１３を用いてフレーム本体５ａを立て起こしてストランド鉄筋籠２７を杭孔３３内に伸展させる。【選択図】図３
