High-performance concrete structural member with multiple layers of prestressed fiber meshes and manufacturing method of high-performance concrete structural member
The invention discloses a multi-layer prestressed fiber net high-performance concrete structural member and a manufacturing method thereof. The multi-layer prestressed fiber net high-performance concrete structural member comprises a member body formed by solidifying high-performance reactive powder concrete. The component main body comprises a plurality of layers of plate structures which are stacked in the height direction; fiber meshes are arranged between every two adjacent plate structures and on the upper surface of the uppermost plate structure and the lower surface of the lowermost plate structure in the plurality of stacked plate structures; and each fiber mesh is pre-embedded and consolidated on the upper surface or the lower surface of the corresponding plate structure after being tensioned by applying prestress. During manufacturing, all the fiber meshes are sequentially positioned and tensioned from bottom to top, and the corresponding plate structures are poured till the fiber meshes on the upper surface of the uppermost plate structure in the multiple plate structures are fixedly connected to the corresponding plate structures. Compared with traditional global dispersion type ultra-high performance concrete, the purposes of greatly reducing the fiber volume mixing amount, improving the material utilization efficiency and reducing the construction cost of structural parts are achieved.
本发明公开了多层预应力纤维网高性能混凝土结构件及其制作方法，包括采用高性能活性粉末混凝土固结成形的构件主体；构件主体包括多层沿高度方向堆叠设置的板结构；每两块相邻的板结构之间，以及位于多块堆叠的板结构中最上方板结构的上表面和最下方板结构的下表面均设有纤维网片；每一纤维网片均在施加预应力进行张拉后，预埋固结在相应的板结构的上表面或者下表面。制作时，从下向上依次定位、张拉每一纤维网片并浇筑相应的板结构，直至多块板结构中最上方板结构上表面的纤维网片被固结在相应的板结构。本发明相比于传统全域弥散型超高性能混凝土达到大幅度降低纤维体积掺量，提高材料利用效率并降低结构件造价目的。
