Construction method for goblet-shaped support super-long multi-layer horseshoe-shaped curved surface space steel structure
The invention discloses a construction method for a goblet-shaped support super-long multi-layer horseshoe-shaped curved surface space steel structure. The steel structure adopts a plurality of large-dip-angle giant steel pipe column core tubes penetrating through a top plate of a basement to support a large-span asymmetric horseshoe-shaped multilayer truss, and the construction method comprises the following steps: 1) mounting a core tube; pre-burying and fixing steel pipe column foundation bolts through a positioning frame; adopting multi-space accurate positioning on a spatial special-shaped circular tube inclined column of the steel pipe column; adopting multiple-space accurate positioning in positioning and mounting of a large-span overweight steel box girder, and reserving an operation hole in a cover plate, wherein welding is facilitated, and the field welding quality of a butt joint opening of the steel box girder is improved; and 2) mounting a truss: splicing the truss on the ground through a positioning jig frame, integrally lifting the truss through a plurality of lifters mounted on the top of a steel tube column of the core tube, and carrying out butt joint on pre-mounted inward-extending cantilever brackets and outward-extending cantilever brackets on the core tube. The method can meet the field mounting requirements of the goblet-shaped support super-long multi-layer horseshoe-shaped curved surface space steel structure.
本发明公开了一种樽形支撑超长多层马蹄形曲面空间钢结构施工工法，钢结构采用多个穿地下室顶板大倾角巨型钢管柱核心筒支撑一个大跨度非对称马蹄形多层桁架，施工工法为：1)安装核心筒，采用定位架对钢管柱地脚螺栓进行预埋固定；钢管柱的空间异形圆管斜柱采用多重空间精准定位；大跨度超重钢箱梁定位安装采用多重空间精准定位，并通过在盖板上预留操作洞口，方便施焊，提高了钢箱梁对接口的现场焊接质量；2)安装桁架，桁架在地面采用定位胎架拼装，采用安装在核心筒钢管柱柱顶的多个提升器对桁架进行整体提升，采用预先安装的内伸悬挑牛腿与核心筒上的外伸悬挑牛腿对接。本发明能够满足樽形支撑超长多层马蹄形曲面空间钢结构现场安装需求。
