Prestressed carbon plate-ECC combined reinforced concrete structure and construction method
The invention discloses a prestressed carbon plate-ECC combined reinforced concrete structure and a construction method. A cement-based composite material ECC layer, a prestressed plate and a cement-based composite material ECC layer outer protective layer are laminated at the bottom of a concrete beam; the plate is protected on the outer side of the plate reinforced by the prestressed plate by utilizing good durability such as crack resistance and impermeability of the cement-based composite material ECC, so that the erosion effect of the external severe environment on the plate is isolated, and meanwhile, the overall bearing capacity of the concrete beam and the crack resistance of the beam bottom can be improved; and the ECC layer is arranged between the prestressed plate and the concrete, so that the stripping of the plate can be delayed due to the characteristics of fine cracks, the interfacial shear stress is effectively transmitted, and the advantage of high tensile strength of the plate is better exerted.
本发明公开了预应力碳板‑ECC组合加固钢筋混凝土结构及施工方法，在混凝土梁底部叠合了水泥基复合材料ECC层、预应力材板以及水泥基复合材料ECC层外护层；利用水泥基复合材料ECC抗裂及抗渗性等良好的耐久性能在预应力板材加固的板材外侧保护板材，隔离外部恶劣环境对板材的侵蚀作用，同时也能提高混凝土梁的整体承载力以及梁底的抗裂缝能力；通过预应力板材和混凝土之间设置的ECC层，细密裂缝的特性则可以延缓板材的剥离，有效地传递界面剪应力，从而更好地发挥板材高抗拉强度的优点。
