摘要
2010年上海世博会西班牙国家馆结构主体为空间异型刚架结构。结构竖向及水平向构件沿建筑立面在不同部位发生扭曲,以与建筑空间扭转曲面相适应,同时要满足结构可拆卸和异地二次安装的要求,这对结构的制作和安装带来巨大的挑战。施工过程中以计算机模拟吊装为基准,同时建立高精度三维工程控制网,采用柱桁架现场拼装后整体吊装和梁桁架空中散拼的吊装技术和半相贯节点、销轴连接及法兰连接等节点施工工艺,保证了安装精度。
The structure of Spain pavilion in World Expo 2010 Shanghai is a special shaped steel space structure. The vertical and horizontal structure members have been curved in 3 dimensions in order to adapt the inner and outer surface of the building,and the structures could be disassembled after the Expo and reinstalled on the other site. This brings the challenge to the structure manufacture and the installation. During the construction, the column trusses were assembled on site before hoisting and beam trusses were installed in the air based on the computer hoisting simulation and controlled by the high accuracy three dimensional measure control network. The partial intersected CHS joints, pin joints and flange connections were applied to guarantee installation precision.
