我单位对传统的混凝土圈梁的支模方法进行了改革。具体做法如下。1.先把定型小钢模拼装好(图1),并事先把支撑件做成如图2、3所示的两部分。2.安装时,将部件①从预留洞穿过,把部件②用2φ8螺栓固定在部件①上,部件①上有8φ10圆孔,可支成梁断面为240,300,350和370毫米4 My organization has reformed the traditional model method of concrete ring beams. The specific approach is as follows. 1. First assemble the small steel mold (Figure 1), and make the support in advance as shown in Figure 2, 3 in two parts. 2. When installing, pass the part 1 through the reserved hole, and fix the part 2 with 2φ8 bolts on the part 1. The part 1 has 8φ10 round holes, and the beams can be cross-sectioned 240, 300, 350 and 370mm 4
