目前在楼板面预埋钢管作外脚手架的连墙件的作法非常普遍(图1),因部分施工人员认为拉杆接合的作法导致脚手架的横向刚度比图1的刚性连接方法弱,导致拉杆接合的作法基本被淘汰(图2)。柔性连接只承受拉力,而拉杆接合既承受拉力也承受压力,按JGJ130—2011中6.4.6条:连墙件必须采用可承受拉力和压力的构 At present, it is very common practice to construct a continuous wall with embedded steel tubes for external scaffolding (Figure 1). Some constructors consider that the tie-bar approach results in a weaker lateral stiffness of the scaffold than the rigid-tie method of Figure 1, The basic approach was eliminated (Figure 2). Flexible connections only bear tensile force, while the pull rod joint both withstand tension and pressure, according to JGJ130-2011 in 6.4.6: even wall pieces must be used to withstand the tension and pressure of the structure
