METHOD FOR CONSTRUCTING REINFORCED CONCRETE STRUCTURE AND REINFORCING BAR SUPPORTING DEVICE
To provide an efficient construction of a reinforced concrete structure whose cross-sectional shape and/or area varies in the vertical direction.SOLUTION: A method for constructing a concrete structure (pier 1) that includes a plurality of main reinforcing bars 5a extending obliquely with respect to the vertical direction includes: a first step of forming a reinforcing bar unit 6a on the ground formed by combining a plurality of reinforcing bars 7, 8; a second step of moving the reinforcing bar unit 6a to a building position Q1; and a third step of connecting the reinforcing bar unit 6a to the main reinforcing bars 5a provided so as to include the building position Q1. The reinforcing bar unit 6a has a plurality of hook portions (hooks 7a, 8a of the reinforcing bars 7, 8) on which the main reinforcing bar 5a can be hooked. The second step includes moving the reinforcing bar unit 6a diagonally downward along the main reinforcing bar 5a to the building position Q1 while the main reinforcing bar 5a is hooked on the hooked portion of the reinforcing bar unit 6a.SELECTED DRAWING: Figure 15
【課題】断面の形状及び／又は面積が鉛直方向で変化する鉄筋コンクリート構造物を効率良く施工する。【解決手段】鉛直方向に対して傾斜して延在する複数の主鉄筋５ａを含むコンクリート構造物（橋脚１）の構築方法は、複数の鉄筋７，８を組み合わせてなる鉄筋ユニット６ａを地上で形成する第１の工程と、鉄筋ユニット６ａを建て込み位置Ｑ１まで移動させる第２の工程と、建て込み位置Ｑ１を含むように設けられた主鉄筋５ａに鉄筋ユニット６ａを結合する第３の工程とを含む。鉄筋ユニット６ａは、主鉄筋５ａを引っ掛け可能な引っ掛け部（鉄筋７，８のフック７ａ，８ａ）を複数有する。前記第２の工程は、鉄筋ユニット６ａの引っ掛け部に主鉄筋５ａを引っ掛けた状態で、鉄筋ユニット６ａを主鉄筋５ａに沿って建て込み位置Ｑ１まで斜め下方に移動させることを含む。【選択図】図１５
