PROBLEM TO BE SOLVED: To prevent a crack with a width greater than 0.05 mm along a beam from appearing on a top surface of a floor slab, in a concrete slab structure having a beam provided in a lower part of the concrete floor slab.SOLUTION: A fiber net is embedded in a position lower by 10-50 mm than a top surface of a concrete floor slab and a corresponding position on a beam. Additionally, the length T of the fiber net is prescribed within a predetermined range with respect to a beam interval L1. Furthermore, the plurality of fiber nets are equally arranged in the longitudinal direction of the beam. An interval B between the adjacent fiber nets is prescribed within a predetermined range with respect to a beam length L2 and a net width b. |
