Full-life durable ballastless track steel bridge deck
The invention discloses a full-life durable ballastless track steel bridge deck, which relates to the technical field of steel bridge decks, and comprises a steel bridge deck arranged along the longitudinal bridge direction, and a bridge deck slab arranged on the upper end surface of the steel bridge deck; the two protection walls are arranged on the two sides of the bridge deck slab at intervals in the longitudinal bridge direction, and a channel connecting mechanism is reserved between the two protection walls and the bridge deck slab, arranged on the upper end face of the bridge deck slab and located in a channel reserved by the two protection walls. The anti-corrosion structure has the beneficial effects that the bridge deck slab and the concrete cushion layer are matched with the connecting mechanism, so that the anti-corrosion structure has the outstanding advantages of simple structure, definite stress, good fatigue performance, long service life and the like, the anti-corrosion problem of the ballastless track steel bridge deck is fundamentally solved, and the long service life and durability of the steel bridge deck slab are realized; the concrete cushion layer and the steel bridge deck form a whole through the stainless steel rib plates and the transverse bridge direction stainless steel ribs and participate in structural stress in a superposed beam mode, the steel consumption of the bridge is reduced, the structural rigidity is improved, and it is guaranteed that operation is more stable.
本发明公开了一种全寿命耐久型无砟轨道钢桥面，涉及钢桥面技术领域，包括沿纵桥向设置的钢桥面，还包括：桥面板，设置在钢桥面的上端面；两个防护墙，纵桥向间距设置在桥面板两侧，两个防护墙与桥面板之间留有通道连接机构，设置在桥面板的上端面，且位于两个所述防护墙留出的通道内。本发明的有益效果是：通过桥面板和混凝土垫层，配合连接机构，具有结构简单，受力明确，疲劳性能好，全寿命耐久等突出优点，从根本上解决了无砟轨道钢桥面的防腐问题，实现了钢桥面板的长寿命耐久，混凝土垫层通过不锈钢肋板和横桥向不锈钢筋与钢桥面形成整体，以叠合梁的方式参与结构受力，减少了桥梁的用钢量，增加了结构刚度，保证运行更平稳。
