Steel-concrete-UHPC (Ultra High Performance Concrete) combined bridge deck slab
The invention relates to a steel-concrete-UHPC combined bridge deck which comprises a bottom steel plate, a common concrete layer and a UHPC ultra-high performance concrete layer, the bottom steel plate is connected with an existing bridge, the common concrete layer is poured on the bottom steel plate, the UHPC ultra-high performance concrete layer is poured on the common concrete layer, and the steel-concrete-UHPC combined bridge deck is formed. Compared with the prior art, the method has the advantages that the anti-cracking performance of the upper edge tension area of the bridge deck slab is effectively improved, the economic value is good, the safety is high, and the material performance is fully played.
本发明涉及一种钢‑混凝土‑UHPC组合桥面板，包括底钢板、普通混凝土层和UHPC超高性能混凝土层，底钢板与既有桥梁相连，普通混凝土层浇筑在底钢板上，UHPC超高性能混凝土层浇筑在普通混凝土层上，组成钢‑混凝土‑UHPC组合桥面板。与现有技术相比，本发明具有有效改善桥面板上缘受拉区的抗裂性能、具有较好的经济价值、安全性高、充分发挥材料性能等优点。
