Roof panel

Abstract

The invention provides a roof panel which comprises a truss structure (C type steel frame structure), an upper bearing surface layer, a lower bearing surface layer and a heat preservation filling layer, wherein the heat preservation filling layer is the middle layer inside the truss structure (C type steel frame structure) of the roof panel, and the upper surface and the lower surface of the truss structure (C type steel frame structure) are connected with bearing surface layers; the bearing surface layers comprise glass fibers, reinforced materials, composite layers containing magnesium and padding, the upper layers and the lower layers of the bearing surface layers are the glass fibers, and a layer of reinforced materials are arranged on the lower layer glass fibers of the upper bearing surface layer; the composite containing magnesium and the padding are arranged in the middle layer, and the glass fibers and the reinforced materials are combined into a composite through viscidity of the composite containing magnesium. According to the roof panel, the truss structure (C type steel frame structure) is simple; the cold bridge and waterproof problems of the structure of the roof panel are solved through the upper bearing surface layer and the lower bearing surface layer; the bearing surface layers can be prefabricated in factories, field forging is not needed, and therefore the construction processes of the roof panel are simplified, and the quality is easy to control. A truss can be assembled in the field, and therefore transportation cost is saved, and production, installation and construction are convenient to conduct.

Description

technical field [0001] The invention relates to a roof panel. It belongs to the field of building materials. Background technique [0002] Roof panels, as the name suggests, refer to the use of the roof of the house to make the roof leak-proof and have certain load-bearing, cold-proof and heat-insulating and other effects. Since the roof panel needs to be able to directly bear the roof load, it needs to have a certain strength and toughness. In addition, the roof panel also needs to have the following basic characteristics: [0003] 1) Weather resistance, anti-corrosion, fire prevention: It is applied under various climatic conditions and shows good weather resistance performance. It exhibits good corrosion resistance in acid, alkali, and salt chemically corrosive environments, and its fire resistance is ≥ 2 hours. [0004] 2) Waterproof performance: After the waterproof material is laid, it can effectively block the infiltration of water. [0005] 3) Wind resistance and...

Problems solved by technology

Then, after about 4-6 hours of drying, the semi-finished product is turned over, and the other side layer is made on site in the same way. Moreover, during the production process, the surface layer slurry will flow to the steel truss and the polycarbonate. In the gap in the middle of the styrene board, the thickness and weight cannot meet the control requirements. The error rate of thickness is 10-30% due to manual operation, and the probability of weight error is 20-40%.

In production practice, it has been found that due to the denser truss structure and steel mesh used for this kind of roof panel, the structure is still relatively complicated, the production site occupies a large area, and the construction speed is not ideal enough. It is impossible to assemble the roof panel on site, thereby saving Transportation costs

Production waste is likely to cause slight pollution to the environment, especially the need for on-site pouring of the surface layer, which is time-consuming and cannot meet large-scale, large-scale and modern production
