Construction method for preinstallation of overhanging I-shaped steel beam of building external scaffold
The invention provides a pre-installation construction method for a cantilever I-shaped steel beam of a building external scaffold, and relates to the technical field of I-shaped steel beam scaffold construction. Comprising the steps of steel beam positioning and paying-off, beam plate reinforcing steel bar manufacturing and mounting, steel beam hoisting and fixing, I-shaped steel beam mounting, buckle limiting protection, reinforcing steel bar hoop embedding, concrete strength calculation, beam plate concrete pouring and scaffold erecting. The steel beam is firstly installed and then the floor structure concrete is poured, so that the installation process of erecting the cantilever scaffold is simpler and quicker, the construction safety is ensured, the construction progress is accelerated, the working face of a subsequent construction floor is not occupied, the construction period is shortened, and the problem that the position deviation of the steel beam and the hoop is large is effectively solved.
本发明提出了一种建筑外脚手架悬挑工字钢梁预安装施工方法，涉及工字钢梁脚手架施工技术领域。包括：钢梁定位放线、梁板钢筋制作与安装，钢梁吊装固定、工字钢梁安装，卡扣限位防护、钢筋抱箍埋设，砼强度计算、梁板砼浇筑，脚手架搭设；通过先安装钢梁后浇筑楼层结构混凝土，使搭设悬挑脚手架的安装工艺更加简单快捷，保证了施工安全，加快了施工进度，有不占用后续施工楼层的工作面、有利于节省工期的优点，有效解决钢梁和抱箍位置偏差较大的问题。
