Description

Technical Field

[0001] This invention relates to the field of glass curtain walls, and more particularly to a composite curtain wall using metal panels and tempered glass in the same building and a construction method thereof. Background Technology

[0002] In one of the airport GTC transportation hub projects undertaken by our company, the GTC main building has two floors including the roof. The first floor has a metal panel curtain wall, while the second floor has a tempered glass curtain wall. The curtain wall height is 27.38 meters, the roof eaves perimeter is 340.5 meters, and the curtain wall perimeter is 277 meters.

[0003] To highlight the design concept and make the overall shape of the GTC main building more aesthetically pleasing, the metal panel curtain wall is installed on the main structure of the first floor of the GTC main building, while the tempered glass curtain wall is installed on the main structure of the second floor of the GTC main building, tilting from the inside of the main building to the outside from the bottom up. This design makes it difficult to connect the metal panel curtain wall and the tempered glass curtain wall. Improper handling of the connection will result in an uncoordinated appearance of the GTC main building, which not only makes it difficult to meet the design and construction requirements, but also makes the construction of the tempered glass curtain wall more difficult due to the outward tilt design, making it difficult to guarantee the construction quality. At the same time, the tempered glass curtain wall is affected by its own weight and the tilt design, resulting in poor overall stability and poor wind resistance, and has many defects.

[0004] Therefore, there is an urgent need for a composite curtain wall system using metal panels and tempered glass in the same building, as well as a construction method, to solve the aforementioned technical problems. Summary of the Invention

[0005] This invention aims to solve the above-mentioned problems, thereby providing a composite curtain wall of metal panels and tempered glass used in the same building and its construction method. The metal panel curtain wall and the tempered glass curtain wall are connected into a whole through the joint, thereby making the appearance of the GTC main building more harmonious, beautiful and simple. At the same time, the setting of the joint reduces the difficulty of connecting the metal panel curtain wall and the tempered glass curtain wall, meets the design and construction requirements, and also realizes the tilting setting of the tempered glass curtain wall. It also solves the defects of poor overall stability and poor wind resistance of the tempered glass curtain wall due to the dual effects of its own weight and tilting setting. In addition, it reduces the construction difficulty of the tilted tempered glass curtain wall and ensures the construction quality.
