Prefabricated laminated slab adopting pre-stretching fiber net anti-cracking process and manufacturing method thereof
The invention discloses a prefabricated laminated slab adopting a pre-tensioning fiber mesh anti-cracking process and a manufacturing method, and belongs to the technical field of assembly type structure engineering. The laminated slab comprises a concrete layer, a fiber mesh, distribution steel bars and truss steel bars; a pre-tensioning method is adopted for carrying out pre-stress tensioning on the fiber grids, pouring is carried out to form the novel laminated slab, a layered formwork overall pouring technology is adopted, the construction problem during pre-stress tensioning of the fiber grids of the component can be effectively solved, the laminated slab adopts the pre-stress grids, the anti-cracking performance of the laminated slab can be effectively improved, and the rigidity of the laminated slab can be improved; and the crack width under the normal use condition is reduced.
本发明公开了一种采用预拉纤维网抗裂工艺的预制叠合板及制作方法，属于装配式结构工程技术领域，叠合板包括混凝土层、纤维网格、分布钢筋和桁架钢筋；采用先张法对纤维网格进行预应力张拉，并进行浇筑形成新型叠合板，采用分层模板整体浇筑工艺，能够有效解决构件纤维网格预应力张拉时的施工难题，叠合板采用预应力网格可以有效提高其抗裂性能，增大刚度，减小在正常使用情况下的裂缝宽度。
