鹦鹉螺状单层钢网壳结构施工技术

Construction Technology of Nautilus Shaped Single-layer Steel Reticulated Shell Structure

青岛东方影都展示中心工程设计为鹦鹉螺状单层钢网壳结构。其构件制作、现场测量定位、支撑胎架设置、大梁安装、卸载均为施工重难点,且工程工期较紧,尤其是弯曲大梁对定位、吊装等要求严格。结合工程实际情况,介绍了构件制作、测量定位、网壳结构施工等关键施工技术。实践证明,采用本技术施工,鹦鹉螺完成后结构曲线柔和优美。

Qingdao Oriental Cinema Exhibition Center project is designed as nautilus shaped single-layer steel reticulated shell structure. The construction difficulties including components manufacture,in-site measuring and location,support jigs setting,beam installation,unloading and tight construction time,especially the strict requirement on curved beams location and installation. Based on the actual conditions,the key construction technology of components manufacture,measuring and location,shell structure are introduced. It proves that the structural lines curves can be realized ideally.
