The invention relates to a prestressed local reinforcing block structure of a cross-shaped steel-fiber composite material, which is used for constraining and reinforcing a local area of a concrete main body and comprises a plurality of prestressed tendons, a plurality of cross-shaped reinforcing ribs and a plurality of cross-shaped reinforcing ribs, the cross-shaped steel members are positioned among the plurality of prestressed tendons; the micro-expansive concrete is poured on the inner sides and the outer sides of the prestressed tendons and the cross-shaped steel members; and the fiber composite material is wound outside the micro-expansive concrete. Compared with the prior art, the cross-shaped steel member and the fiber composite material are comprehensively applied, the compressive strength and the overall performance of the concrete in the pressed area are remarkably improved, the construction process is simplified, prefabrication and assembly are facilitated, the construction progress can be obviously accelerated, and an effective solution is provided for the stability and the safety of a prestressed structure.
本发明涉及一种十字型钢‑纤维复合材料的预应力局部加强块结构，用于对混凝土主体局部区域进行约束加固，所述预应力局部加强块结构包括：若干预应力筋；位于若干预应力筋之间的十字型钢构件；浇筑在所述预应力筋和十字型钢构件内侧和外侧的微膨胀混凝土；以及缠绕在所述微膨胀混凝土外部的纤维复合材料。与现有技术相比，本发明综合应用十字型钢构件和纤维复合材料，显著提升受压区混凝土的抗压强度和整体性能，简化了施工过程，适合预制和拼装，可明显加快施工进度，为预应力结构的稳定性和安全性提供有效解决方案。
