Structure of external wall facing layer

Abstract

The invention relates to a structure of an external wall facing layer. The structure of the external wall facing layer is characterized by comprising a plurality of structural units, wherein each structural unit comprises a biological nano-film layer, a paint coating layer, an air interlayer layer, a wire mesh layer, an insulating layer, an external wall of a building, a waterproof material layerand waterproof mortar, wherein structures on both sides of each structural unit are sequentially provided with the insulating layer, the wire mesh layer, the air interlayer layer, the paint coating layer and the biological nano-film layer from the exterior wall of the building to the outside; the structure of the middle part of each structural unit is sequentially provided with the insulating layer, the wire mesh layer, the air interlayer layer and the waterproof material layer from the exterior wall of the building to the outside; the paint coating is used for forming a slope to a waterproofmaterial layer from thick to thin; and the two sides of each waterproof material layer are filled with the waterproof mortar. The construction method is simple, convenient and low in improvement cost;the scope of application is wide. The dust removal effect of the building is good, the maintenance cost of the building is reduced, the service life of the outer wall is prolonged, and the structureof the external wall facing layer can adapt to various building outside facade practices.

Description

technical field [0001] The invention belongs to the field of construction engineering and building wall structure, and relates to a structure for reducing the service life of the exterior wall finish layer from being exposed to moisture and sunlight. Background technique [0002] At present, most of the exterior walls of buildings in my country often use stucco paint to decorate the facade. However, in the wet state for a long time due to rainfall and damp, and then exposed to the sun for a long time, the decorative layer of the building wall will easily swell and fall off, reducing the service life of the outer wall of the building. At the same time, the decorative layer of the building is easy to accumulate dust and affect the overall building. The appearance of the building requires manual cleaning and maintenance and replacement of the finish layer, which increases the cost of building maintenance. Therefore, a new way is needed to reduce the cost of building maintenanc...
