Fabricated steel-concrete combined rigid frame bridge beam and construction method thereof
The invention discloses a fabricated steel-concrete combined rigid frame bridge beam which comprises a plurality of prefabricated main beam sections, pier columns and cross beam sections, the adjacentprefabricated main beam sections are bolted through the cross beam sections, and the pier columns are inserted into the cross beam sections to form a hidden cross beam structure. A cover beam is hidden in the main beam structure, the building height is reduced, the aesthetic feeling is improved, the hidden cross beam structure is made into a steel prefabricated part, the hoisting weight is low, and on-site construction is convenient and fast. Slotted holes are formed in the cross beam sections, cross beam shearing force connecting pieces are arranged in the slotted holes, the extending sections of the pier columns are inserted into the slotted holes, rigid connection of the pier columns and the bent cap is achieved through high-strength concrete grout, the steel consumption of the structure is reduced through system advantages, and the manufacturing cost is saved. Meanwhile, the invention discloses a construction mode, main manufacturing of the main beam structure is carried out in aprefabrication factory, the engineering quality can be guaranteed, the method is suitable for the steel-concrete composite beam with a large span, the structural advantages of the steel-concrete composite beam can be brought into full play, and good technical and economic benefits and wide application prospects are achieved.
本发明公开了一种装配式钢‑混凝土组合刚构桥梁，包括若干预制主梁节段、墩柱、横梁节段，相邻的预制主梁节段通过横梁节段栓接，该墩柱插入横梁节段中形成暗横梁结构。通过将盖梁藏入主梁结构中，降低了建筑高度，提高了美感，将该暗横梁结构制成钢预制件，吊重较小，现场施工便捷。横梁节段内部设置槽孔，槽孔内设置横梁剪力连接件，将墩柱的伸入段插入槽孔并通过高强混凝土浆实现墩柱与盖梁的刚接，利用体系优势降低了结构的用钢量，节省了造价。同时公开一种施工方式，将主梁结构主要的制造放在了预制厂，有利于保证工程质量，适用于较大跨径的钢混组合梁，且有利于充分发挥钢混组合梁的结构优势，具有良好的技术经济效益及广阔的应用前景。
