钢网架起步跨提升施工技术

Construction Technology of Starting Span Lifting of Steel Net Frame

钢网架结构是一种杆系结构,构件主要承受轴向力,截面尺寸相对较小,具有空间受力小、刚度大、重量轻、抗震性能好等优点,且在建筑平面形状上也能适应各种形状要求,满足各类使用功能,但这也给施工技术提出了新的挑战。钢网架起步跨提升施工技术,针对筒壳拱形网架的起步跨安装有独特的优势,且无需搭设脚手架进行安装,可大幅节约施工成本,取得良好的社会和经济效益。

The structure of steel net frame is a kind of bar frame structure. The members mainly bear axial force.The section size is relatively small, and it has the advantages of small spatial force, large stiffness, light weight,and good seismic performance. And in the shape of the building plane,it can also adapt various planar shapes and meet the various functions of use. But this also presents new challenges for the construction technology. The steel net frame starting span improvement construction technology has unique advantages for the initial span installation of cylindrical arched net frames. And no scaffolding is required for installation, which greatly saves construction costs and obtains good social and economic benefits.
