    • PROBLEM TO BE SOLVED: To provide a method of reinforcing a reinforced concrete column by which assured construction and adhesive strength can be expected even if a construction surface is brought into contact with underground water and wetted and the construction is difficult in the method for reinforcing against an impact force by fixing a reinforcement plate to the outer surface of a column body by adhering to an anchor.
      SOLUTION: This method of reinforcing a reinforcement concrete column comprises the step of disposing the reinforcement plate such as a steel plate on the outer surface of the column body of a reinforced concrete with the anchor bolt interposed therebetween to provide a very small gap therebetween, the step of depositing a shrinkage-compensating mortar at the portion of the lower surface of the reinforcement plate at the lower part of the column body in contact with underground water for cutting off water by sealing the very small gap between the reinforcement plate and the surface of the column body through all the peripheral edges by fitting a rubber packing and placing a resin mortar therein, the step of removing the air and moisture in the gap between the column body and the reinforcement plate by evacuation, the step of placing a hard resin into the gap while evacuating the gap, the step of fixing the anchor bolt to the column body by placing a filler, and the step of bonding the anchor bolt to the reinforcement plate.

    • 要解决的问题:提供一种增强钢筋混凝土柱的方法,即使施工表面与地下水接触并且在该方法中难以接合,也可以确保结构和粘合强度 用于通过将锚固件固定在柱体的外表面上来固定加强板来抵抗冲击力。 解决方案:这种增强钢筋混凝土柱的方法包括将钢板等加强板设置在钢筋混凝土柱体的外表面上,其间插入有锚栓,以提供非常小的间隙 其间,在柱体下部的加强板的下表面的部分处,与地下水接触以沉积收缩补偿砂浆的步骤,以通过密封加强板和加强板之间的非常小的间隙来切断水 通过装配橡胶垫片并将树脂砂浆放置在其中,通过所有周边边缘的柱体的表面,通过撤离去除柱体和加强板之间的间隙中的空气和水分的步骤, 将树脂填充到间隙中,同时排出间隙,通过放置填料将锚定螺栓固定到柱体的步骤,以及粘合步骤 e锚杆到加强板。 版权所有(C)2008,JPO&INPIT
