Paving construction process for roofs of steel framework composite building

The invention provides a paving construction process for roofs of a steel framework composite building. The paving construction process comprises the steps that a roof framework and roof panels are prepared, the roof panels are bond to the bottom surface and the top surface of the roof framework, concrete is prepared, the roof framework is filled with the concrete, the concrete is vibrated, a supporting framework is erected on the building, the supporting framework is paved with the roofs of the steel framework composite building, seam filling pipes are plugged in roof plate seams between every two adjacent roofs of the steel framework composite building, the roofs of the steel framework composite building and the seam filling pipes or the supporting framework are welded, and roof plate seams are filled with filler. By the adoption of the technical scheme, the concrete filling the roofs of the steel framework composite building is vibrated, the internal and external temperature difference is reduced, after paving and filling with the seam filling pipes, the filler is used for filling to enable the roof plate seams to be kept consistent, the thermal expansion rate of the building roof is kept uniform, twisting and deformation are avoided, and the roof waterproof grade and the construction quality are improved.
