Rail transit steel-concrete composite beam with sound insulation function
The invention relates to a rail transit steel-concrete composite beam with a sound insulation function, and relates to the technical field of bridge construction; the rail transit steel-concrete composite beam comprises a steel-concrete bridge deck slab, two steel main beams and a plurality of transverse supports; the two steel main beams are arranged on the two sides of the steel-concrete bridge deck slab respectively in the cross bridge direction, and the bottom ends of the steel main beams are connected with the steel-concrete bridge deck slab; and the plurality of transverse supports are arranged at intervals in the longitudinal bridge direction, the two ends of each transverse support are connected to the top ends of the two steel main beams respectively, and the transverse supports, the steel-concrete bridge deck slab and the steel main beams jointly define a sound insulation cavity. According to the steel-concrete composite beam, the mechanical property advantages of the two materials are exerted, the structural bearing capacity and flexural rigidity are enhanced, the problem that a bridge deck slab in a hogging moment area cracks is solved, when a vehicle travels in the sound insulation cavity, propagation of wheel track noise can be effectively isolated, and train operation sound pollution is reduced. And meanwhile, the steel structure can be subjected to factory prefabrication, the construction quality is guaranteed, and the construction efficiency is correspondingly improved.
本申请涉及一种自带隔音功能的轨道交通钢混组合梁，涉及桥梁施工技术领域，轨道交通钢混组合梁包括钢混桥面板、两个钢主梁和多个横撑，两个钢主梁沿横桥向分设于钢混桥面板的两侧，且钢主梁的底端与钢混桥面板连接；多个横撑沿纵桥向间隔设置，横撑的两端分别连接于两个钢主梁的顶端，并与钢混桥面板和钢主梁共同围设形成隔音腔室。本申请的钢混组合梁发挥两种材料的力学性能优势，增强结构承载能力和抗弯刚度，避免了负弯矩区桥面板开裂问题，车辆在隔音腔室内行车，可有效隔绝轮轨噪音的传播，降低列车运营声污染。同时钢结构可进行工厂化预制，施工质量得到保证，施工效率也相应提高。
