扣件式钢管支承架构配件及搭设质量现场调查与分析
Parameter survey on steel tubular scaffold components and installation quality
摘要
Abstract
In order to provide the parameter basis for the design and calculation of the supporting frame,ran-dom sampling of the support frame of the building and municipal 10 sites was conducted,and the indexes such as the wall thickness,the weight of the fastener and the tightening moment of the fastener bolts were investiga-ted.The results show that based on the actual situation of the steel pipe and fastener of the current supporting frame and the present quality,in the design of the supporting frame,the thickness of the steel pipe should be taken as 2.7 mm.Only about 10% fastener tightening moment in the sampling project is up to the standard, and the proportion of tightening moment sampling must be enlarged in the actual project;The tightening mo-ment of the sampling fastener is concentrated in the 20~40 N·m,the resistance of the fastener to the sliding capacity should be reduced accordingly.关键词
