FRP grating and ECC fiber concrete combined roof waterproof combined structure

The invention discloses an FRP grating combined ECC fiber concrete roof waterproof combined structure. The structure comprises an ECC fiber concrete base layer, a heat preservation layer, an ECC fiber concrete top layer and an FRP grating. The waterproof composite structure is good in durability, easy to construct, convenient to maintain and low in cost, meanwhile, the tensile strength, tensile strain and deformation capacity in a temperature field of concrete can be greatly improved, the surface impact resistance and stress resistance can be further improved by using the FRP grating, and the service life of the concrete is prolonged. Cracks of the concrete caused by dry and wet deformation, temperature deformation and structural deformation are avoided; the double ECC fiber concrete layers enable the composite structure to have two defensive lines, the waterproof reliability is greatly improved, and the composite structure is suitable for being popularized and used in the waterproof technology of building ro
