Description

TECHNICAL FIELD

[0002] Curtain wall is the outer wall of the building, like a curtain hanging, also known as suspended wall, is a light weight wall with decorative effect commonly used in modern large and high-rise buildings. Curtain wall is composed of panel and supporting structure system, which can have a certain displacement capacity relative to the main structure or have a certain deformation capacity, does not bear the main structure of the building envelope or decorative structure. The curtain wall contains metal plate curtain wall, which generally includes single aluminum plate, composite aluminum plate, aluminum plastic plate, stainless steel plate, titanium alloy plate and color steel plate, among which aluminum plate curtain wall dominates in metal curtain wall. Its lightweight material reduces the load of the building, providing a good selection condition for high-rise buildings, and has excellent waterproof, antifouling and corrosion resistance.

[0003] With the development of the construction industry, there are many forms of glass curtain wall today, and the types vary greatly. The modeling and aesthetic degree of aluminum plate curtain wall are required to be higher, such as diversification and building streamline in architectural art; this requires the aluminum plate to be installed according to the design requirements to adjust the installation angle of the curtain wall aluminum plate. However, the existing installation device is basically similar to the hinge structure disclosed in CN114439134B, which is a kind of aluminum plate spherical curtain wall and construction method. The hinge structure is used to achieve the mutual rotation between the adjacent two aluminum plates, thereby controlling the installation angle between the adjacent two aluminum plates. After connecting the aluminum plates with the structure, the aluminum plates are connected in a piece, and when a certain aluminum plate needs to be adjusted in angle, the other aluminum plates may be driven or directly stuck, and the angle of a single aluminum plate cannot be adjusted. At the same time, when adjusting the angle of the aluminum plate, the angle adjustment of the hinge is limited by the angle of the shaft, and can only be adjusted in the same direction, and the change of the angle is also very limited, which has certain limitations on the appearance modeling of the curtain wall, and it is also difficult to apply it to the installation of more aluminum plate curtain walls.
