Description

Technical Field

[0001] This invention relates to the field of curtain wall duct sealing technology, and in particular to a structure for sealing the connection between ducts and curtain walls. Background Technology

[0002] In building facade construction, the appearance of the curtain wall is particularly important, especially in modern architecture, where it not only serves as an enclosure but also forms a crucial part of the building's exterior. With the development of architectural aesthetics, the integrity and beauty of the building facade have become key design elements. Therefore, the close integration of outdoor ducts and the curtain wall structure is especially important, and a harmonious and unified appearance is a crucial standard for evaluating construction quality. However, traditional curtain wall vent designs typically expose them at the joints between curtain wall sections or at the exposed frame trim. While this arrangement is relatively simple to construct, it visually disrupts the overall aesthetic effect of the building facade and fails to meet the high aesthetic demands of modern architecture.

[0003] Traditional curtain wall and duct connection sealing structures also have several technical shortcomings. Firstly, traditional connection methods have low support strength, making them unable to withstand various external forces that ducts may encounter during use, such as wind pressure and snow loads, posing certain safety hazards. Secondly, traditional sealing structures have insufficient sealing performance, easily leading to water leakage at the joints, which not only affects the building's functionality but may also damage the internal structure. Furthermore, traditional designs are relatively complex to install and maintain, increasing construction costs and the difficulty of later maintenance. Therefore, there is an urgent need for a new type of duct and curtain wall connection sealing method to solve the problems existing in current technology and meet the dual requirements of modern architecture for both aesthetics and safety.
