Steel structure reinforcing device suitable for two-way curved arch bridge and construction method of steel structure reinforcing device
The steel structure reinforcing device comprises an arch ring arranged in the bottom of an arch wave in the to-be-reinforced two-way curved arch bridge, the arch ring is formed by a plurality of steel pipe arches filled with concrete, the two ends of each steel pipe arch are installed on an arch seat through steel pipe arch supports, the arch seats are fixedly arranged on bridge piers, and the two ends of each steel pipe arch are fixedly connected with the bridge piers. The bending degree of each steel pipe arch is matched with the cambered surface of the bottom of the arch wave, each steel pipe arch penetrates through the original cross beam and is located between every two adjacent arch ribs, a plurality of box-shaped cross beams are arranged at the bottom of the arch wave along the cambered surface at intervals, each box-shaped cross beam is fixedly installed on the arch ribs, and the box-shaped cross beams are connected with the arch ring into a whole through a plurality of sets of fastening assemblies. Load borne by the two-way curved arch bridge can be finally transmitted to the bridge piers sequentially through the box type cross beams, the fastening assemblies and the concrete filled steel tube arch rings, the bearing capacity of the two-way curved arch bridge is remarkably improved, the reinforcing cost is low, steel structure construction is convenient, meanwhile, the overall appearance structure of the bridge is not damaged, and popularization is facilitated.
本发明公开了一种适用于双曲拱桥的钢结构加固装置及其施工方法，包括设在待加固双曲拱桥中拱波底部内的拱圈，该拱圈由多根灌有混凝土的钢管拱形成，每根钢管拱的两端均通过钢管拱支座安装在拱座上，拱座固设在桥墩上，每根钢管拱的弯曲程度与拱波底部弧面吻合，每根钢管拱穿过原横梁、并位于相邻两个拱肋之间，拱波底部沿弧面间距设有多条箱型横梁，且每条箱型横梁固定安装在拱肋上，箱型横梁通过多套紧固组件与拱圈连接为一体。本发明可将双曲拱桥承受的载荷依次通过箱型横梁、紧固组件、钢管混凝土拱圈最终传递到桥墩上，显著提高了双曲拱桥的承载力，且加固成本低、钢结构施工方便，同时不破坏桥梁的整体外貌结构，便于推广普及。
