关于型钢悬挑扣件式钢管脚手架的几点思考

在选择型钢悬挑扣件式钢管脚手架的支座结构形式时,应考虑尽量避免钢管扣件承受偏压、剪切和扭曲等作用。悬挑梁端的斜拉钢丝绳是安全储备,在确定悬挑梁的锚固和悬挑长度时,应综合考虑钢筋压环允许的拉应力值、螺栓与混凝土的容许黏结强度、混凝土局部承压能力等因素,在特殊部位采取加强措施,并正确使用和维护悬挑架。

Some Thoughts on Steel Pipe Scaffold of Steel Hang Fastener

To identify the structure of steel pipe scaffold of steel hang fastener,we must ensure that the steel fastener will not be affected by forces of side pressure,clipping and distorting.Side-draw steel rope in the tilting end is a safety insurance, so in identifying the anchor fastener and the length of the tilting,a comprehensive approach must be taken to take into account the minimum drawing refection strength allowed by the steel pressure circle,sticking tensity of the concrete and screw top and the pressure resistance strength of the concrete,and in special places,consolidation must be taken with rational utilization and maintenance of the scaffold.
