我们在使用钢模支地梁、圈梁模板时,采用了以下两种工具,代替木龙骨和木拉杆,收到了良好的经济效果。1.П形卡具:用Φ12圆钢热加工成П形,见图1。当用240毫米宽的圈梁时,П形卡具宽度为:b+2a+12=240+2×22+12=296毫米;当用于370毫米宽的圈梁时,它的宽度为420毫米。2.支撑卡具:用Φ12圆钢焊接而成,见图2。使用时这种卡具穿在圈梁底面下的墙身预留的龙骨孔里,以支撑圈梁两侧面的钢模板。支撑卡横向焊 We used the following two tools when using steel molds to support the ground beam and ring beam formwork. Instead of wood keel and wooden tie rod, we received good economic results. 1. П-shaped fixtures: Φ12 round steel hot processed into П-shaped, see Figure 1. When using a 240 mm wide ring beam, the П clamp has a width of b+2a+12=240+2x22+12=296 mm; when used on a 370 mm wide ring beam, it has a width of 420 mm. Mm. 2. Support clamps: Welded with Φ12 round steel, see Figure 2. When used, this kind of fixture is worn in the keel hole reserved in the wall below the ring beam to support the steel template on both sides of the ring beam. Support card transverse welding
