钢屋架现场制作由于受现场机械设备和操作水平的影响,往往不同程度地存在一些质量问题,给工程留下隐患。因此,施工中应注意以下几点。1.节点板、垫板必须采用剪板机下料,杆件优选无齿锯下料,禁止气割下料,因为气割下的板、杆,不仅尺寸不一致,影响构件的美观,而且在高 Due to the influence of on-site mechanical equipment and operation level, steel roof truss production often has some quality problems to some extent, leaving hidden dangers for the project. Therefore, the following points should be noted during construction. 1. The gusset plate and backing plate must be cut by shears, and the rods are preferably not sawed by cutting teeth. Gas cutting is prohibited. Because the plates and rods under gas cutting are not only inconsistent in dimensions, but also affect the aesthetic appearance of the components.
