A prefabricated building exterior wall thermal insulation decorative slab

Abstract

The invention discloses a prefabricated building exterior wall thermal insulation decorative large board, which belongs to the technical field of new building materials, and includes a laminated board, a heat insulation board and a heat preservation board. Good heat-conducting and insulating elastic rubber, the laminated board is fixedly connected to the left inner wall of the heat insulation board, and the insulation board is fixedly connected to the right side of the heat insulation board. Through the setting of the curved surface of the insulation board, the cold wind spreads when it hits the insulation board from the front. At the same time, the curved surface of the insulation board acts as a guide for the cold air flow, avoiding increasing the diffusion area of ​​the cold air, and through the setting of two air ducts, the wind force is converted into the power of the rotating rod, which effectively consumes the wind force and avoids In case of problems such as wind damage, through the setting of the air duct, the wind force is converted into power, which drives the wear-resistant rubber A and wear-resistant rubber B to rub against each other, and the heat generated by the friction is transmitted to the wall through the bonding plate, further Increase the insulation effect.

Description

technical field [0001] The invention relates to a prefabricated building exterior wall thermal insulation and decorative slab, which belongs to the technical field of new building materials. Background technique [0002] Wall board is a kind of building board that plays the role of strengthening the wall, preventing fire and moisture, etc. In the development process of wall board, more and more attention is paid to its performance advantages. [0003] The main function of the existing exterior wall panels with thermal insulation is to resist the invasion of cold wind, but when the cold wind hits the front, the wind will expand to the surrounding after hitting the wall panels, which increases the distance between the wall panels and the cold wind. The contact area of ​​the brought cold air accelerates the temperature dissipation of the wall, resulting in a reduction in the thermal insulation effect. Therefore need a kind of new exterior wall insulation board badly to solve t...

AI Technical Summary

Problems solved by technology

[0005] 1) The use of prefabricated installation technology for thermal insulation wall panels is not obvious

The external insulation material is made of polystyrene board, and the installation techniques mainly include point-and-point method of polystyrene board and wall installation, and polystyrene board and wall one-time pouring molding method, such as hanging and pasting methods. Special environmental factors such as strong winds, corrosion, and the influence of wet work will cause condensation and mildew on the inner surface of the outer wall, freeze-thaw cycles, and material corrosion will cause the insulation board to fall off, crack, bulge, and fall off; technical measures and construction methods will lead to maintenance difficulties. Affect the service life of the board and the effect of building insulation and facade

[0006] 2) The energy-saving and environmental protection performance of thermal insulation wallboard materials has great limitations, and the application and development prospects are restricted. The construction site waste of thermal insulation materials will pollute the surrounding environment to a certain extent

[0007] 3) The integrated design of thermal insulation and decorative performance of the board is insufficient, and the construction is cumbersome. The decorative surface layer of the board is easy to fall off under the influence of environmental factors such as ultraviolet rays, high temperature, severe cold, strong wind, and rain, which affects the appearance of the city

[0008] Aiming at the existing structure technology of thermal insulation wall panels and the shortage of wind energy utilization, exploring the research of installation and assembly, effective use of wind energy, and decorative integrated composite wall panels has entered people's field of vision.
