高空大跨度型钢悬挑式钢管支模架施工技术

在高层建筑施工中,高空大跨度悬挑混凝土结构因其位置高、跨度大、结构自重大以及风荷载大等原因,无法直接利用外墙脚手架,采用高空型钢悬挑式钢管支模架能够很好地解决这一难题。文章通过某工程实例,介绍了高空大跨度型钢悬挑式钢管支模架施工的施工方案、工艺流程及操作要点,说明了高空大跨度型钢悬挑式钢管支模架的施工质量标准。

The construction technology of high-altitude long-span steel cantilever-style steel frame formwork

In the high-rise building construction,because of its location high,large span,heavy structure weight,as well as wind loads and other factors,high-altitude long-span cantilever concrete structures can not directly use the external walls of the scaffolding,using high-altitude steel cantilever-style steel frame formwork can be a very good solution to this problem.Through an engineering example,this article introduced the construction program,technological process and operation points of high-altitude long-span steel cantilever-style steel frame formwork,and its quality standard.
