[0046] The present application will be further described below in conjunction with the drawings and specific embodiments.

[0047] Reference Figure 1This invention provides a facade curtain wall system with a closely spaced tensioned aluminum alloy mesh structure and its construction method, designed to improve the light transmittance of buildings. It is primarily applicable to the installation of glass curtain walls. The facade curtain wall system utilizes support columns to support the tensioned aluminum alloy mesh structure. This mesh structure is openwork, offering high light transmittance and good transparency. The support columns serve as both the main structure and the installation foundation for the glass curtain wall, eliminating the need for the existing curtain wall joists. This simplifies construction steps, improves efficiency, and avoids obstruction caused by the joists. The support columns have a rectangular outer contour and are connected by connecting rods. When setting the connecting rods, the number of rods is minimized while still meeting load requirements, thereby maximizing light transmittance and meeting the building's high light transmittance requirements. Furthermore, the combination of the support columns and the glass curtain wall can create unique and creative shapes, showcasing a perfect fusion of architecture and technology. The facade curtain wall system with a closely spaced tensioned aluminum alloy mesh structure and its construction method are described below with reference to the accompanying drawings.
