Description

Technical Field

[0001] The utility model relates to the technical field of building curtain walls, in particular to a building curtain wall structure. Background Art

[0002] In the decoration industry, the curtain wall keel is a supporting structure in the building's exterior curtain wall system, used to fix and support wall materials, such as aluminum veneer. As a new type of building material, aluminum veneer is now more and more widely used in indoor and outdoor decoration projects.

[0003] The main shortcomings of existing building curtain wall technology include:

[0004] Insufficient stability and wind pressure resistance: In traditional curtain wall systems, the connection between curtain wall panels and keels may not be strong enough, resulting in the curtain wall panels being easily loosened or damaged under severe weather conditions such as strong winds, affecting the stability and safety of the overall structure.

[0005] Difficult installation and adjustment: In some traditional curtain wall systems, the installation process is complicated and difficult to adjust. Once the aluminum veneer or other curtain wall materials are improperly installed, adjustments may be very time-consuming and labor-intensive, increasing construction costs and time.

[0006] Inadequate waterproofing and thermal insulation: Existing curtain wall structures may be inadequate in terms of waterproofing and thermal insulation. Improper gap treatment or inappropriate material selection can lead to water vapor penetration and heat loss, affecting the comfort and energy efficiency of the building.

[0007] Electrochemical corrosion problem: Metal materials, especially the connection points between different metal materials in the curtain wall system, may undergo electrochemical corrosion, which will reduce the durability of the curtain wall system and require regular replacement or maintenance, increasing long-term maintenance costs.

[0008] Limited aesthetics: In some existing curtain wall designs, it may be difficult to achieve more innovative and diverse aesthetic designs due to structural and installation technology limitations. This limits the creativity of architects and designers in curtain wall exterior design.

[0009] Difficulty in maintenance and replacement: Traditional curtain wall systems can face challenges when curtain wall panels need to be replaced or maintained, especially in high-rise buildings, where these tasks are not only difficult but also costly.

[0010] These shortcomings reflect challenges in curtain wall design, material selection, installation techniques, and maintenance strategies, which need to be overcome through technological innovation and design improvements. Utility Model Content
