对于扣件式钢管脚手架的搭设,笔者曾对永川市在建的47个工程进行过调查,发现它们在不同程度上都存在安全隐患,而且都忽视了同—个问题:大横杆没有交替置于立杆内侧和外侧,而是靠在立杆同一侧,如图1。为什么会这样呢?我认为,目前搭设扣件式钢管脚手架一般只注重杆件间距、剪刀撑、连墙杆等,而未对脚手架工程进行设计和计算。实际上,扣件式钢管脚手架的纵向刚度
For the erection of fastener-type steel scaffolds, I have investigated 47 projects under construction in Yongchuan City and found that they have hidden dangers to varying degrees, and all overlooked the same problem: the large crossbar is not alternated. On the inside and outside of the pole, but on the same side of the pole, as shown in Figure 1. Why is this happening? I think that the erection of fastener-type steel scaffolds currently focuses only on the spacing between rods, scissors, connecting rods, etc., without designing and calculating the scaffolding project. In fact, the longitudinal stiffness of fastener-type steel scaffolding
