Large-cantilever eccentric ring steel structure and construction method thereof
The invention discloses a large-cantilever eccentric ring steel structure and a construction method thereof. The steel structure comprises eccentric annular upper and lower layer steel structures, the rear parts of the eccentric annular upper and lower layer steel structures are connected through a plurality of groups of steel columns, each group of steel columns comprises a plurality of steel columns, the bottoms of each group of steel columns are connected with a reinforced concrete cylinder on a foundation, the front parts of the upper and lower layer steel structures are provided with hollow circles which are vertically opposite, and the peripheries of the upper and lower layer steel structures are in an overhanging state. The upper-layer steel structure and the lower-layer steel structure each comprise an outer ring truss and an inner ring truss, and the outer ring trusses and the inner ring trusses are connected through a plurality of inter-ring straight trusses which are perpendicularly arranged in a crossed mode. A prestress inhaul cable system is installed on the top of the upper-layer steel structure and used for improving the bearing capacity of the upper-layer steel structure and preventing the overhanging part of the upper-layer steel structure from deforming. The problems of special shapes, large-size cantilevers and poor foundations are solved, the structural bearing capacity is high, and the structural strength and rigidity are guaranteed.
本发明公开了一种大悬挑偏心环钢结构及其施工方法。钢结构包括偏心环状上、下层钢结构，两者后部通过多组钢柱相连，每组钢柱包括多个钢柱，每组钢柱底部与基础上的一钢筋混凝土筒相连，上、下层钢结构的前部设有上下相对的空心圆，上、下层钢结构的四周呈悬挑状态。上、下层钢结构均包括外圈环桁架和内圈环桁架，外圈环桁架与内圈环桁架之间通过垂直交叉布设的多个环间直桁架相连。上层钢结构的顶部安装有预应力拉索系统，预应力拉索系统用于提高上层钢结构的承载力并避免上层钢结构的悬挑部分发生变形。本发明解决了异型、大尺寸悬挑、基础不佳的问题，结构承载力强，结构强度和刚度有保障。
