Description

Technical Field

[0001] The invention relates to the technical field of building engineering, and in particular to a double-layer thermal insulation, fireproof and waterproof decorative aluminum plate. Background Art

[0002] Traditional metal roofing systems such as patent number CN201120570763.1 disclose a metal roofing structure. Most of these roofing structures are directly installed with insulation cotton and metal plates on the steel structure. This roofing system has only one insulation layer and waterproof layer. Its roofing system has poor insulation and waterproof performance. It is suitable for general industrial and civil buildings with a roof waterproofing grade of III. Moreover, this roofing system will cause sealant aging and metal plate surface corrosion after long-term exposure to the sun and rain. Once the metal roofing panel is damaged, it will cause roof rainwater leakage, affecting the normal use of the building. In cold areas, snow accumulation in early spring is prone to form snow dams. Because the snow dam prevents the melted snow water from being discharged, it forms accumulated water, which penetrates into the roof from the gaps where the metal roofing panels meet, causing water leakage, affecting the use. In recent years, some double-layer waterproof, heat-insulating and sound-insulating roofing systems have also appeared in the industry, but most of these roofing systems have no fireproof effect, do not have internal and external decoration effects, and have poor waterproof effects. In addition, the overall quality is heavy and the installation is more troublesome. Summary of the invention

[0003] The purpose of the present invention is to provide a double-layer thermal insulation, fireproof and waterproof decorative aluminum plate. The thermal insulation and fireproof cotton can reduce the heat loss in the venue and has a certain fireproof effect. The filament non-woven geotextile has good mechanical function and good water permeability. The waterproof breathable membrane can prevent water from penetrating. The aluminum profile square tube is convenient for drainage of the aluminum plate, and the overall waterproof effect is good. The waterproof perforated aluminum single plate one and the waterproof perforated aluminum single plate two are coated with a layer of fluorocarbon, so that the aluminum plate has better low temperature and high temperature resistance. The overall structure is light, convenient for transportation and on-site installation, and the perforated aluminum plate can be built-in with lighting pipelines, which has a good concealing effect. The technical problems of the poor waterproof effect and weak decorative function of the conventional double-layer thermal insulation aluminum plate are solved. The many technical effects that can be produced by the preferred technical scheme among the many technical schemes provided by the present invention are described in detail below.

[0004] In order to achieve the above object, the present invention adopts the following technical solution:
