Description

Technical Field

[0002] As a commonly used material in modern building facade decoration projects, building dry hanging panels are currently widely used in various civil and public buildings. Building dry hanging panels have the characteristics of light total weight and good thermal insulation performance. During installation, they are fixed to the building facade through keels. There is usually a certain distance between them and the building exterior wall. This part of the space can play a role in thermal insulation.

[0003] As we all know, lightweight building materials have a low thermal conductivity, and such lightweight building materials are less effective in improving the thermal storage performance of buildings. After the common building dry-hanging panels are installed, they cannot be replaced or moved as a fixed whole, and their thermal insulation performance cannot be adjusted at any time according to climate changes. In addition, lightweight building materials such as dry-hanging panels themselves are difficult to improve the thermal storage capacity of buildings. It is difficult to simultaneously meet the requirements of low thermal conductivity, strong thermal storage capacity and light weight in the existing technology. Utility Model Content
