DEFORMATION CONTROL METHOD AND BELT-LIKE FASTENING MEMBER FOR REINFORCING STEEL PLATE USED ON REINFORCED CONCRETE COLUMN

PROBLEM TO BE SOLVED: To provide a deformation control method for a reinforcing steel plate used on a reinforced concrete column that is implemented easily even in a narrow work space and capable of certainly preventing swelling of the reinforcing steel plate.SOLUTION: When a reinforced concrete column is reinforced by placing a reinforcing steel plate around the reinforced concrete column and injecting and hardening mortar between the reinforced concrete column and the reinforcing steel plate, the method comprises, between the step for covering an outer periphery of the reinforced concrete column with the reinforcing steel plate and the step for injecting and hardening mortar; the step for fitting a plurality of rod-form members that extend along a height direction of the reinforced concrete column at an outside of a central part of the reinforcing steel plate; the step for winding a belt-like member on outside of the rod-form members; and the step for fastening both ends of the belt-like member using a fastening member while applying tension on the belt-like member, so as to forcibly hold down a swollen part of the reinforcing steel plate when the reinforcing steel plate swells during mortar injection. 【課題】狭い施工スペースでも施工が容易で、かつ補強用鋼板のはらみ出しを確実に防止することのできる鉄筋コンクリート柱補強用鋼板の変形抑制方法を提供する。【解決手段】鉄筋コンクリート柱の周囲に補強用鋼板を配置するとともに、鉄筋コンクリート柱と補強用鋼板との間にモルタルを注入して硬化させ、鉄筋コンクリート柱を補強する際に、補強用鋼板にて鉄筋コンクリート柱の外周を覆う工程とモルタルを注入して硬化させる工程との間に、前記補強用鋼板の中央部外側に、前記鉄筋コンクリート柱の高さ方向に沿って延長する複数の棒状部材を取付ける工程と、前記棒状部材の外側に帯状部材を巻き付ける工程と、前記帯状部材の両端部を、締結部材を用いて、前記帯状部材を緊張させた状態で締結する工程とを設けて、モルタルの注入時に補強用鋼板がはらみ出したときに、はらみ出しを強制的に押さえ込むようにした。【選択図】図４
