Prefabricated laminated slab made in accordance with pretensioning fibermesh anti-cracking process and manufacturing method thereof

A prefabricated laminated slab made in accordance with a pretensioning fibermesh anti-cracking process, the laminated slab comprising:

• fiber grids, wherein a concrete layer is arranged above the fiber grids, and the concrete layer is internally provided with distribution bars and truss bars;
• wherein the fiber grids are orthogonal grids with overhanging fiber whiskers, a fiber mesh size defining a respective pore diameter of the grids is 20 mm (0.788 inch) to 50 mm (1.97 inch), and each fiber grid is a tensioned grid;
• wherein a thickness of the concrete layer is 60 mm (2.364 inch) to 120 mm (4.728 inch), and a particle size of concrete aggregate located in the concrete layer is smaller than the pore diameter of each fiber grid;
• wherein the distribution bars comprise longitudinal distribution bars and transverse distribution bars, and the longitudinal distribution bars and the transverse distribution bars are all located above the fiber grids;
• and
• wherein the truss bars comprise two bottom longitudinal bars, top longitudinal bars and a plurality of connecting bars, the two bottom longitudinal bars are located between the longitudinal distribution bars, the top longitudinal bars are located above the concrete layer, and two ends of the connecting bars are respectively connected with the bottom longitudinal bars and the top longitudinal bars.
