INSTALLATION METHOD OF REINFORCEMENT CAGE
PROBLEM TO BE SOLVED: To facilitate manufacture and installation of a reinforcement cage 10 and installation of a spacer for setting a covering concrete thickness, when constructing a box body 3 that is a tunnel-like reinforced concrete structure.SOLUTION: A reinforcement assembly stand 11 is installed over a mold 8, in a work space 5 located on an extension line in a horizontal direction of a concrete casting space 9 partitioned by the mold 8. A reinforcement cage 10 is assembled on the reinforcement assembly stand 11, and the reinforcement cage 10 is moved by sliding from the reinforcement assembly stand 11 onto the mold 8. In the step for assembling the reinforcement cage 10, a roller 12 that also serves as a spacer is fitted rotatably on a lower reinforcement 10c of the reinforcement cage 10 in a direction perpendicular to an axis. The roller 12 is made to roll on the reinforcement assembly stand 11 and the mold 8 in the step for moving the reinforcement cage by sliding. A radius of the roller is the same with a covering concrete thickness, and no spacer needs to be installed separately.SELECTED DRAWING: Figure 2
【課題】 鉄筋コンクリート製のトンネル状構造物である函体３の構築に際し、鉄筋籠１０の製作及び設置、かぶり厚設定用のスペーサの設置を容易にする。【解決手段】 型枠８により区画されるコンクリート打設空間９の水平方向の延長上の作業空間５に、型枠８に連ねて、鉄筋組立架台１１を設置する。鉄筋組立架台１１上で鉄筋籠１０を組み立て、鉄筋組立架台１１上から型枠８上へ鉄筋籠１０をスライド移動させる。ここにおいて、鉄筋籠１０を組み立てる工程では、鉄筋籠１０の軸直角方向下側鉄筋１０ｃに、スペーサを兼ねるローラ１２を回転可能に取付ける。そして、前記スライド移動させる工程では、鉄筋組立架台１１及び型枠８上で前記ローラ１２を転動させる。前記ローラの半径はかぶりに一致しており、別途スペーサの設置は不要である。【選択図】 図２
