Light roofing system

Abstract

The invention discloses a light roofing system, comprising a substrate layer and a waterproof surface layer, wherein the waterproof surface layer comprises a functional coating layer which is made of functional paint and a waterproof layer which is made of waterproof paint; and the functional paint comprises a base material and a functional material, the functional material comprises an inorganicflaky material, an inorganic high-rigidity wear-resistant material and polymer powder with good toughness, the adding amount of the inorganic flaky material accounts for 1-8% of the total weight of the functional paint, the adding amount of the inorganic high-rigidity wear-resistant material accounts for 2-15% of the total weight of the functional paint and the adding amount of the polymer powderwith good toughness accounts for 1-8% of the total weight of the functional paint. In the light roofing system, all materials, except the substrate layer, are selected from the paint, therefore, the light roofing system is light in weight, the burden of a load-bearing mechanism is effectively reduced, and the unnecessary material consumption is avoided. As the light roofing system only comprises the waterproof surface layer and the substrate layer, the roof structure is simple, the expansion coefficients of the materials approach to each other, the water leakage caused by roof crazing can be effectively avoided, the maintenance cost is low; and as the paint is used as the surface layer, the use is safe.

Description

technical field [0001] The invention relates to the technical field of roof structures, in particular to a light roof system with simple structure. Background technique [0002] In recent years, the energy crisis has intensified globally and has become a major theme for the sustainable development of countries and societies. Building energy consumption accounts for about 30% of the total energy consumption in developed countries. Under the general situation of energy conservation and emission reduction, the demand for energy conservation in engineering construction continues to increase. [0003] like figure 1 As shown, the existing building roof system, such as the master roof in the "Building Standard Design Architecture Atlas of Central and Southern Regions", consists of a base material layer 1, a slope layer 2, a leveling layer 3, a waterproof layer 4, and heat insulation Layer 5, isolation layer 6, protective layer 7, decorative layer 8 and other multi-layered and mul...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the multi-layer structure composed of various materials, the construction process is complicated and cumbersome, the material consumption is large, the construction period is long, and professional construction personnel are required, so the cost is high;

[0005] 2. Since most of the materials used are mortar, waterproof coiled material, waterproof coating, thermal insulation materials and other construction materials, the load-bearing structure of the house has a heavy burden, and the consumption of steel reinforcement materials and energy and building materials during the construction process are large;

[0006] 3. The multi-layer superimposed structure of different materials is adopted. Due to the inconsistent expansion coefficients of the materials of each layer, it is easy to cause roof cracking and water leakage;

Once the roof structure is damaged artificially or naturally, it is difficult to check and detect. It can only be removed as a whole and resurfaced, which consumes a lot of resources and high maintenance costs;

[0008] 5. Existing roofing systems need to consume a lot of non-recyclable materials during construction and maintenance, and generate a lot of construction waste, which not only consumes excessive resources, but also causes damage to the environment;

[0009] 6. Most of the materials used in the existing roofing system contain flammable materials, especially waterproof and thermal insulation materials, which may even produce toxic smoke when burned, posing a great safety hazard
