按照常规的施工方法,在砖墙上留置圆形洞时,必须支木模圆拱券台。这样,不仅浪费人力、物力,而且,施工难度也比较大。为了解决这个问题,我单位采用了“钢筋笼拱券台法”。即根据设计留洞尺寸大小,制作两三个钢筋圈,即24墙用2个,37墙用3个,然后,用直钢筋将钢筋圈连接成笼。在砌砖墙时,将 According to the conventional construction method, when a circular hole is left on a brick wall, a wooden arched coupon must be supported. In this way, not only manpower and material resources are wasted, but also the construction is relatively difficult. In order to solve this problem, my unit adopted the “rebar cage arch law”. That is, according to the design of the size of the hole, two or three reinforcement rings are made, that is, 24 for the wall and 3 for the 37 wall. Then, the reinforcement ring is connected to the cage by the straight reinforcement. When building a brick wall, it will
