Bridge deck structure and bridge
The embodiment of the invention provides a bridge deck structure, a bridge deck structure body and a ballastless track, the bridge deck structure body comprises a cross beam arranged in the transverse bridge direction and an orthotropic bridge deck slab, and the middle part of the cross section of the orthotropic bridge deck slab is concave downwards; and the ballastless track is fixed at the top of the middle concave part of the bridge deck slab through a track mounting structure. By the adoption of the bridge deck structure, installation precision, anti-shearing capacity and stability are high, and due to the fact that the track structure and the bridge structure are designed in a collaborative and integrated mode, on the premise that rigidity and strength are guaranteed, the overall structure height of the ballastless track, the bridge deck slab and the lower trussed beam is reduced, and construction cost is reduced. The problems that in the prior art, a traditional bridge deck structure is low in installation precision, poor in stability and high in structure height, and if existing building height limitation exists in front of and behind a bridge span point, bridge structure design cannot be achieved are solved.
本申请实施例提供一种桥面结构，其桥面结构主体及无砟轨道，其中桥面结构主体包括沿横桥向设置的横梁及正交异性桥面板，其中正交异性桥面板横截面的中间部分下凹；无砟轨道通过轨道安装结构固定在所述桥面板中间下凹部分的顶部。采用这种桥面结构，安装精度高、抗剪切能力强、稳定性高，并且由于将轨道结构和桥梁结构协同一体化设计，在保证刚度和强度的前提下，降低无砟轨道、桥面板和下桁梁的总体结构高度，解决了现有技术中传统桥面结构安装精度低、稳定性差、结构高度高，若在桥梁跨点前后存在既有建筑限高，则桥梁结构设计无法实现的问题。
