用适于低高度架的定性要求来搭设和控制有较高高度的脚手架,其稳定性不能满足施工需要,必须同时考虑以定量方法进行控制。本文主要介绍英国关于扣件式钢管脚手架的实施规范,讨论脚手板、小横杆、脚手架操作平台的布置、搭设所采用的定量要求;根据不同情况采用不同形式的系杆拉结脚手架,并按面积法则进行布设;以及纵向斜撑、侧向斜撑、平面斜撑的布置。
The erection and control of scaffolds with higher heights are required to meet the qualitative requirements of low-height stands. The stability cannot meet the construction requirements, and control must be considered simultaneously with quantitative methods. This article mainly introduces the British implementation specification for fastener steel pipe scaffolding, discusses the layout of the scaffolding, small cross bar, scaffolding operation platform, and the quantitative requirements for the erection; according to different situations, different forms of tie bar pull knot scaffolds are used, and The area rule is laid; and the arrangement of longitudinal braces, lateral braces, and plane braces.
