南京美术馆新馆钢结构施工关键技术

Key Technology of Steel Structure Construction of New Nanjing Art Museum

南京美术馆新馆主钢结构为极不规则的超大跨度、大悬挑、多层回字形桁架结构,在施工过程中采用地面原位整体拼装后再整体提升方式,整体提升重量达到8016吨,是近十年来国内外建筑钢结构整体提升重量及提升难度最大的项目。针对本项目钢结构施工过程,本文对相关关键技术进行了探讨。

The main steel structure of the new Nanjing Art Museum is a very irregular structure with super span,large overhanging,and multi-layer circular truss.During the construction process,the integral lifting method is adopted after the overall assembly of the ground in situ.The integral lifting weight reaches 8,016 tons,which is the most difficult project to lift the integral weight of the building steel structure at home and abroad over the past decade.Aiming at the steel structure construction process of this project,the paper discusses the relevant key technologies.
