一、概述国外采用钢管脚手架已有六十余年历史,由于种种原因,我国在60年代初期才开始推广。近年来,随着城乡建筑规模的扩大,钢管脚手架应用量越来越大,钢管脚手架配件的生产量也越来越大。但是,随着钢管脚手架应用量的增加和应用范围的扩大,脚手架安全事故亦时有发生。本文综述钢管脚手架类别、构造、稳定性验算与试验以及有关安全事项,供读者参考。钢管脚手架按承载能力可分为轻型、中型及重型三类。各类脚手架额定载重量、应用范围及主要规格如表1所示。钢管脚手架所用的钢管大多为φ48×3.5。有些国家采用壁厚4.06或4.45mm钢管,抗拉强度为340～475N/mm~2,流限为 First, an overview of the use of steel scaffolding abroad has more than 60 years of history, due to various reasons, China began to promote in the early 60s. In recent years, with the expansion of the scale of construction in urban and rural areas, the number of steel pipe scaffolding applications is increasing, and the production of steel pipe scaffolding accessories is also increasing. However, with the increase in the number of steel pipe scaffolding applications and the expansion of the scope of application, scaffold safety incidents have also occurred from time to time. This article reviews the classification, construction, stability calculation and testing of steel pipe scaffolds and related safety issues for the reader’s reference. Steel pipe scaffolding can be divided into light, medium and heavy categories according to the bearing capacity. Various types of scaffolding rated load, application range and main specifications are shown in Table 1. Most steel pipes used for steel pipe scaffolds are φ48×3.5. Some countries use steel pipes with a wall thickness of 4.06 or 4.45mm, tensile strengths of 340 to 475N/mm2, and flow limits of
