在高层建筑施工中,悬挑脚手架占外架工程量的60%以上。《建筑施工扣件式钢管脚手架安全技术规范》(JGJ 130—2011)规定:每个型钢悬挑梁外端宜设置钢丝绳或钢拉杆,与上一层建筑结构斜拉。钢丝绳、钢拉杆不参与悬挑钢梁受力计算,即每根型钢上的钢丝绳是作为安全储备使用的,由此可以看出钢丝绳的重要性。在《钢丝绳夹》(GB/T5976—2006)中规定:在钢丝绳公称直
In high-rise building construction, cantilevered scaffolding accounted for more than 60% of the amount of the project. The “Code for Safety of Fastener Steel Pipe Scaffolding for Construction” (JGJ 130-2011) stipulates that the outer end of each cantilevered beam should be equipped with steel wire rope or steel pull rod, which is to be inclined with the structure of the previous building. Rope, steel rod does not participate in the calculation of cantilevered steel beams, that is, each steel bar on the profile is used as a safety reserve, which can be seen the importance of rope. In the “steel wire rope clamp” (GB / T5976-2006) states: the rope straight
