REINFORCEMENT CAGE AND CONSTRUCTION METHOD OF CONCRETE STRUCTURE
To provide a reinforcement cage capable of extending/contracting vertically and changing a diameter thereof.SOLUTION: A reinforcement cage 1 has a plurality of flexible spiral strands 11a, 11b arranged in a circumferential direction of the reinforcement cage 1 leaving an interval, the strands being disposed inside and outside with varying directions of spiraling, and the outer and inner strands 11a, 11b are connected rotatably at an intersection. The reinforcement cage 1 realizes extended and contracted states by changing an angle of intersection between the inner and outer strands 11a, 11b, and furthermore the reinforcement cage 1 is capable of changing a diameter to a small diameter in the extended state and to a wide diameter in the contracted state of the reinforcement cage 1.SELECTED DRAWING: Figure 2
【課題】上下に伸縮可能であり、且つ径を変えることのできる鉄筋籠等を提供する。【解決手段】鉄筋籠１は、鉄筋籠１の周方向に間隔を空けて配置された可とう性を有する複数本の螺旋状のストランド１１ａ、１１ｂを、旋回方向を変えて内外に設け、内外のストランド１１ａ、１１ｂを交差部で回転可能に接合したものである。鉄筋籠１は、内外のストランド１１ａ、１１ｂの交差角が変化することにより、伸長状態と収縮状態とを実現でき、さらに、鉄筋籠１は伸長状態で細径、収縮状態で広径となり、鉄筋籠１の径を変えることができる。【選択図】図２
