拱型门式钢管脚手架整体稳定性试验研究

Experimental study on integral stability of steel tubular scaffold with arch skeleton frames

针对新型拱型门式钢管脚手架在东南沿海地区的广泛应用现象,本文以MF0817型门式钢管架为例,进行了五组整体承载力试验,分析该型号门式脚手架的结构性能。通过对连墙件、脚手板、交叉支撑和水平拉杆等构配件的不同参数设置,研究构配件对门式脚手架极限承载力和失稳模式的影响,为工程应用和推广提供指导建议。

In view of the wide application of the new arch portal steel pipe scaffold in the southeast coastal area,taking mf0817 portal steel pipe scaffold as an example,five groups of overall bearing capacity tests are carried out to analyze the structural performance of this type of portal scaffold.By setting different parameters of components and parts such as wall connecting parts,scaffold board,cross support and horizontal tie rod,the influence of components and parts on the ultimate bearing capacity and instability mode of portal scaffold is studied,so as to provide guidance and suggestions for engineering application and popularization.
