REINFORCING BAR FIXING METHOD AND HOLE ROUGHENING DEVICE
To develop a roughening treatment technology capable of obtaining sufficient adhesion strength without confirming a roughening state.SOLUTION: A method for fixing the reinforcing bar to an existing concrete skeleton comprises: a step of drilling with a core drill; a step of roughening the drilled hole wall by a roughening device; a step of filling a filling material into the hole, inserting the anchor reinforcing bar into the hole, and curing the filling; and a step of fixing the reinforcing bar to the existing concrete skeleton, and the roughening step controlling a rotational speed and an in-hole movement speed of a roughing tool of a roughing device.SELECTED DRAWING: Figure 1
【課題】目荒し状態を事後確認することなく、十分な付着強度が得られる目荒し処理技術を開発する。【解決手段】コアドリルで削孔する工程、削孔された孔壁を目荒装置で目荒しする工程、充填材を孔内に充填し、定着筋を孔に挿入し、充填材を養生する工程と、を備えた、既設コンクリート躯体に定着筋を固定する既設コンクリート躯体に鉄筋を定着する方法であって、目荒しする工程は、目荒装置の目荒し工具の回転速度と孔内移動速度を管理する鉄筋定着方法。【選択図】図１
