某MALL大型钢构吊装施工技术分析

Construction Technology Analysis of a Mall Large Steel Structure Lifting

某中心MALL美术馆六层及屋面层原设计为预应力混凝土结构,考虑到施工难度及工程进展,提前进行了结构形式,将预应力混凝土结构变更为钢结构,对变更后的钢结构吊装的施工关键技术进行了研究。

The six-storey and roof of MALL Art Museum of a certain center were designed as pre-stressed concrete structure. Considering the difficulty of construction and the progress of engineering, the pre-stressed concrete structure was changed into steel structure in advance. The key construction technology of hoisting of the altered steel structure was studied.
