Photocatalyst heat insulation building wall structure

Abstract

The invention discloses a photocatalyst heat insulation building wall structure. The photocatalyst heat insulation building wall structure comprises a building outer wall body and a photocatalyst layer, an inner heat preservation layer and an inner decoration layer are sequentially arranged on the inner side of the building outer wall body from inside to outside, and an outer heat preservation layer, a damp-proof layer and the photocatalyst layer are sequentially arranged on the outer side of the building outer wall body from inside to outside; and the photocatalyst layer is coated on the outer side of an outer hanging plate, and the inner side of the outer hanging plate is fixed on the building outer wall body through a keel framework. The photocatalyst layer on the surface of a buildingwall can adsorb moisture in air, and dirt is prevented from making contact with the surface of the wall; due to the wavy form and the porous characteristic of the outer hanging plate, the surface areaof the wall is increased, the moisture condensation capacity and the moisture absorption capacity of the wall surface are improved, moisture transpiration and heat absorption are achieved when the air temperature rises, thus the wall surface is cooled, and the effects of cooling, heat insulation and self-cleaning are achieved in combination with an air flowing interlayer.

Description

technical field [0001] The invention relates to the technical field of building heat-insulating wall structures, in particular to a photocatalyst heat-insulating building wall structure. Background technique [0002] Architecture is an artificial environment created by human beings based on certain scientific laws and cultural backgrounds in order to meet the basic needs of human beings by using the material and technological means they have mastered. The physical environment of a building directly affects the physiological feelings of users, and is an important factor in determining green and healthy buildings. The exterior wall of a building is the direct contact interface between the internal environment of the building and the external environment, and acts as an enclosure. Its physical properties profoundly affect the physical environment inside the building, especially the indoor thermal environment. The exterior wall of the building needs to have sufficient strength ...

AI Technical Summary

Problems solved by technology

In an environment with high wind speed, the surface of the outer wall is easily stained, which affects the appearance of the facade, and even causes damage to the surface, and the physical properties of the internal structure fail
