Method for upside-down jacking construction of high-altitude multi-layer and high-rise hanging steel structure
The invention discloses an upside-down jacking construction method for a high-altitude multi-layer and high-rise hanging steel structure, which adopts an upside-down jacking method to construct the high-altitude multi-layer and high-rise hanging steel structure and ensures that the stress form of a rod piece is not changed in the construction process. The influence of adverse stress caused by stress form transformation of a structural rod piece in the traditional steel structure construction process is avoided; low-altitude assembly is adopted, so that the danger of high-altitude operation is avoided, the mounting precision is improved, and meanwhile, the construction cost of high-altitude temporary supporting and high-altitude hoisting is reduced; by the adoption of the upside-down jacking technology, the hanging structure can be always in a pulled state in the construction process, the dangerous state that the hanging structure is changed from being pressed to being pulled is avoided, the safety coefficient of the construction process is improved, and the mechanical and labor cost is reduced.
本发明公开了一种高空多高层吊挂钢结构倒装顶升施工的方法，采用倒装顶升的方法对高空多高层吊挂钢结构进行施工，保证了施工过程中杆件的受力形式不变，避免了传统钢结构施工过程结构杆件受力形式转变带来的不利应力的影响；低空拼装，避免了高空作业的危险，提高了安装的精度，同时减少了高空临时支撑和高空吊装的施工成本；采用倒装顶升技术，可使吊挂结构在施工过程中始终为受拉状态，避免了吊挂结构从受压转受拉的危险状态，提升了施工过程的安全系数，降低了机械和人工成本。
