Description

Technical Field

[0001] This invention relates to the field of curtain wall installation technology, and in particular to a symmetrical shuttle-shaped cable-stayed curtain wall structure and its construction method. Background Technology

[0002] As glass curtain walls become increasingly common on building exteriors, their height and width are also increasing to meet the demands for both lighting and aesthetics. However, relying solely on the back-mounted joists within the curtain wall to fix the glass sometimes fails to meet structural and safety requirements. Therefore, cable-stayed curtain walls have been proposed in existing technologies. Current cable-stayed curtain walls are installed using only vertical cables, relying solely on the vertical force of the cables and the horizontal force of the horizontal bars for balance, resulting in poor stability and weak anchoring force. Therefore, targeted design is needed to improve the stability of the cable system within limited space and further enhance the auxiliary role of the cables in supporting the curtain wall joists. Summary of the Invention
