Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to an indoor and outdoor double-layer curtain wall system and its construction method. Background Technology

[0002] In recent years, with the rapid development of my country's economy, glass curtain wall structures have been widely used as exterior building decorations in construction projects. However, the energy-saving effect of ordinary glass curtain walls is not satisfactory. As human society develops, the demand for improved living standards is becoming increasingly strong, leading to a surge in the consumption of non-renewable energy sources and a decrease in their availability. Countries around the world are paying more and more attention to energy conservation, especially in the field of building construction, where energy-saving requirements are becoming increasingly stringent from design to manufacturing.

[0003] In the existing technology, in order to meet the requirements of energy saving and environmental protection of glass curtain walls, there are designs for double-layer split unit curtain walls.

[0004] However, existing double-layer split unitized curtain walls are usually a simple combination of two types of curtain walls in design, which is costly and inconvenient to install, maintain and replace. If damage occurs during use, it is difficult to restore, which brings great inconvenience to later maintenance and panel replacement. The overall cost is too high and does not meet the national requirement of "increasing revenue and reducing expenditure" to reduce construction costs. Summary of the Invention

[0005] The purpose of this invention is to provide an indoor and outdoor double-layer curtain wall system and construction method to solve the problems mentioned in the background art. The existing double-layer split unit curtain wall is usually a simple combination of two curtain walls in design, which is costly and inconvenient to install, maintain and replace. If damage occurs during use, it is difficult to restore, which brings great inconvenience to later maintenance and panel replacement. The overall cost is too high and does not meet the national requirements of "increasing revenue and reducing expenditure" to reduce construction costs.
