Steel-ultrahigh-toughness concrete combined bridge deck slab based on steel bar truss connection
The invention discloses a steel-ultrahigh-toughness concrete combined bridge deck slab based on steel bar truss connection. The combined bridge deck slab is composed of a steel bridge deck top plate, stiffening ribs, upper chord steel bars, lower chord steel bars, web member steel bars, upper part and lower part connecting steel bars and ultrahigh-toughness concrete. The web member steel bars are pressed into a wave shape and welded with an upper chord member and the lower chord member through a welding machine, and therefore a single steel bar truss is formed. The steel bar trusses are transversely and continuously placed side by side along the bridge floor, are connected into a whole through the upper part and lower part connecting steel bars and then are welded on the bridge deck top plate to form a steel framework. The ultrahigh-toughness concrete is poured on the bridge floor steel framework to play a role in protecting the bridge deck. In the combined bridge deck deck slab system, the stress mode of the steel bar truss system is reasonable, good overall working performance is achieved, and the fatigue performance of the structure is improved while the cost and construction complexity are reduced.
本发明公开了一种基于钢筋桁架连接的钢‑超高韧性混凝土组合桥面板，由钢桥面顶板，加劲肋，上、下弦钢筋，腹杆钢筋，上、下部连系钢筋和超高韧性混凝土组成。腹杆钢筋压制成波浪形，并通过焊接机械将其与上下弦杆焊接，从而形成单个钢筋桁架。各钢筋桁架沿桥面横向连续并排放置，上下部连系钢筋将各钢筋桁架连接成一个整体后再与桥面顶板焊接可形成钢骨架。超高韧性混凝土浇筑在桥面钢骨架上，起到保护桥面的作用。本发明提出的组合桥面板体系中，钢筋桁架体系受力模式合理，具有良好的整体工作性能，在降低成本和施工复杂度的同时改善了结构的疲劳性能。
