Abstract
The utility model discloses a steel bridge floor which comprises a steel bridge body and a bridge floor protective layer. The bridge floor protective layer is paved on the steel bridge body and used for improving the corrosion resistance and the friction resistance of the steel bridge body. The bridge floor protective layer consists of,,an inner layer, an intermediate layer and an outer layer from bottom to top, wherein the inner layer is coated with antirust primer paint, the intermediate layer is a strengthening layer and the outer layer is a reinforcing layer. The bridge floor protective layer is paved on the surface of the steel bridge body, and the bridge floor protective layer has strong bonding capacity and good flexibility and wear resistance, can protect the steel bridge body against corrosion for 15-20 years and prevent the layering of the steel bridge body after service for 9-15 years, and effectively improves the compression resistance and the loading capacity of the steel bridge floor and reduces the load of the bridge, so that the service life of the bridge is prolonged, the comprehensive cost is reduced and the bridge construction period is shortened.
