我公司在张家口医学院附属医院外科病房楼施工中,采用了提升脚手架工艺。该工程为现浇钢筋混凝土框架结构,全高41m,长57m,宽13m,层高4.2～3.7m,共10层。开间分6m、6.6m和7.2m三种;进深为5.7、4.2m(楼道宽3m)。按传统施工方法,脚手杆、脚手板、排木、铅丝等用量大,施工费用高,周期长,重复劳动多,每层均须搭、拆,效率低。针对上述问题,我们采用提升脚手架施工。实践表明,该工艺取得了较好的技术经济效果。一、施工方案 1.脚手架采用钢管搭设内脚手架,再从内脚手架上悬挑外脚手架,内外脚手架联成整体。
In the construction of the surgical ward building of the Affiliated Hospital of Zhangjiakou Medical College, our company adopted the scaffolding process. The project is a cast-in-situ reinforced concrete frame structure with a total height of 41m, a length of 57m, a width of 13m, and a floor height of 4.2-3.7m, a total of 10 layers. Open space is divided into 6m, 6.6m and 7.2m three; depth is 5.7,4.2m (bridge width 3m). According to the traditional construction method, the amount of footwork, scaffolding, row of wood, lead wire, etc. is large, the construction cost is high, the cycle is long, the repeated work is more, each floor must be taken and removed, and the efficiency is low. In response to the above problems, we use scaffolding construction. Practice shows that this process has achieved a good technical and economic effect. First, the construction program 1. Scaffolding using steel pipe built scaffolding, and then from the internal scaffold overhanging external scaffolding, internal and external scaffolding into a whole.
