Cable-stayed bridge of steel truss reinforced concrete beam
The invention discloses a cable-stayed bridge of a steel truss reinforced concrete beam, which comprises a main beam for directly bearing the load of a bridge deck, wherein the main beam is erected ona side pier and penetrates through a bridge tower, a plurality of pairs of stay cables are arranged between the bridge tower and the main beam, and the main beam is formed by assembling a plurality of prefabricated segments along the bridge direction. Each prefabricated segment is composed of a reinforced steel truss and a concrete beam, and the reinforced steel trusses and the concrete beams arespliced and fixed. The concrete beam is internally provided with a reinforced steel truss node plate, and the reinforced steel truss node plate is connected with a lower chord node of the reinforcedsteel truss. The main beam is of a combined structure of the reinforced steel trusses and the concrete beams, the material performance advantages of steel and concrete are brought into full play, thestructural rigidity is high, the power performance is good, and the problem that creep deformation of a large-span concrete main beam is difficult to control is effectively solved. The cable-stayed bridge adopts a prefabricated segment assembling method for construction, the construction period is shortened, the construction quality is improved, later creep is reduced, and mechanical and standardized construction is achieved.
本发明公开了一种钢桁加劲混凝土梁的斜拉桥，包括直接承受桥面荷载的主梁，所述主梁架设在边墩上且穿过桥塔，所述桥塔与主梁之间设置有多对斜拉索，所述主梁顺桥向由多个预制节段拼装而成。所述预制节段由加劲钢桁、混凝土梁组成，所述加劲钢桁、混凝土梁拼接固定。所述混凝土梁中设置有加劲钢桁节点板，所述加劲钢桁节点板与加劲钢桁的下弦节点相连。本发明主梁采用加劲钢桁、混凝土梁的组合结构，充分发挥钢材、混凝土各自的材料性能优势，结构刚度大且动力性能好，有效解决了大跨度混凝土主梁徐变变形难以控制的难题。采用预制节段拼装法施工，节省了施工工期，提高了施工质量，减少了后期徐变，实现机械化、标准化施工。
