Beam end connecting structure of simply supported rotary continuous steel-concrete combined continuous beam and construction method
The invention relates to a beam end connecting structure of a simply supported continuous steel-concrete combined continuous beam, which comprises a steel main beam, a welding stud connecting piece, a perforated connecting steel plate and an end cross beam, the steel main beam is composed of an upper flange plate, a web plate and a lower flange plate, the end cross beam is of a reinforced concrete structure, and the end cross beam is located at a middle fulcrum of the continuous beam and is connected with the web plate through a connecting piece. The beam ends of the steel main beams of every two adjacent spans extend into the end cross beams in the middle to be fixed, the perforated connecting steel plates are fixed between the upper flange plates of the steel main beams of every two adjacent spans through welding stud connecting pieces, and the lower flange plates of the steel main beams of every two adjacent spans are connected through opposite vertex steel plates. The problem that the beam ends of the steel beams are discontinuous is well solved, meanwhile, the problem that connection is not convenient due to the fact that the steel main beams are large in interval is solved, the adverse effects of steel beam pressing and concrete plate pulling of the steel-concrete combined simply-supported-to-turn continuous beam are improved, it is guaranteed that the whole steel-concrete combined simply-supported-to-turn continuous beam is continuously stressed, and the construction efficiency is improved. The durability of the structure is improved; and the service life of the bridge is prolonged.
本发明涉及一种简支转连续钢‑混组合连续梁的梁端连接构造，包括钢主梁、焊钉连接件、开孔连接钢板、端横梁，所述钢主梁由上翼缘板、腹板和下翼缘板组成，所述端横梁为钢筋混凝土结构，所述端横梁位于连续梁中支点处，相邻两跨的钢主梁梁端均伸入中间的端横梁内部固定，开孔连接钢板经焊钉连接件固定于相邻两跨的钢主梁的上翼缘板之间，相邻两跨的钢主梁的下翼缘板之间经对顶钢板连接。很好地解决了钢梁梁端不连续的问题，同时解决了钢主梁间隔大而不利连接的问题，改善了钢‑混组合简支转连续梁的钢梁受压以及混凝土板受拉的不利影响，保证了钢‑混组合简支转连续梁的整体受力连续，提高了结构的耐久性和桥梁的使用寿命。
