Large-span suspension steel structure reverse construction method
The invention discloses a large-span suspension steel structure reverse construction method which comprises the following steps: S1, constructing steel structures on two sides of a large-span area to three layers, arranging 12 support columns on the ground of the large-span area, and arranging concrete foundations on the lower parts of the support columns; and S2, the 3-4 layers of steel structures in the large-span area are installed, square steel is placed between the 3 layers of cross beams and the supporting columns in the steel structures in the large-span area, and concrete of the 3 layers and the 4 layers of floors in the large-span area is poured. The construction method is reasonable in design, the problem that the high-altitude installation difficulty of a large-span multi-layer steel structure is large is solved through the steel structure installation construction technology with temporary supports arranged from bottom to top, the large-span area steel structure can be synchronously constructed in the construction process of main structures on the two sides, the construction progress is accelerated, and the purpose of shortening the construction period is achieved; and meanwhile, a strip cutting method is provided, the problem that deformation of the steel structure is too large due to sudden unloading is effectively solved, and construction safety is guaranteed.
本发明公开了一种大跨度悬挂钢结构逆作施工方法，包括以下步骤：S1，将大跨度区域两侧钢结构施工至3层，在大跨度区域地面设置12根支撑柱，并在支撑柱下部设置混凝土基础；S2，将大跨度区域的3‑4层钢结构安装完成，大跨度区域钢结构中3层横梁与支撑柱之间放置方钢，并浇筑大跨度区域中3层和4层楼面混凝土。本发明设计合理，通过设置临时支撑、自下而上的钢结构安装施工工艺，解决了大跨度多层钢结构高空安装难度大的难题，且能够在两侧主体结构施工的过程中，同步施工大跨度区域钢结构，加快施工进度，达到节约工期的目的，同时提出分条切割法，有效解决钢结构因突然卸载变形过大的难题，保证施工安全。
