Open-frame glass curtain wall is the most traditional form, which is widely used and has reliable working performance. Compared with the hidden frame glass curtain wall, it is easy to meet the construction technology requirements.
There must be a gap between the glass and the aluminum frame of the open-frame glass curtain wall component to meet the necessary activity space for the temperature change and displacement of the main structure. The gaps are filled with elastic materials (such as rubber strip) and sealed with silicone structural adhesive (weather-resistant adhesive for short) if necessary.
2. The hidden frame glass curtain wall is a silicone structural adhesive for glass (hereinafter referred to as structural adhesive) bonded to the aluminum frame. In most cases, metal connectors are not added. The all-aluminum frame is hidden behind the glass, forming a large-area all-glass mirror.
Glass and aluminum frame are completely bonded by structural adhesive, which bears the influence of glass weight, wind load, earthquake and temperature change. Therefore, structural adhesive is the key to the safety of hidden frame curtain wall. The latest hook node is easy to install.
Reflective glass curtain wall refers to the building envelope or decorative structure, which can be displaced relative to the main structure through the supporting structure system and does not share the role of the main structure. There are two kinds of walls: single-layer and double-layer glass. Glass curtain wall is a beautiful and novel way of building wall decoration, which is a remarkable feature in the era of modernist high-rise buildings. 20 13 according to FLAP (deadly light awareness program), in Toronto alone, one to nine million migratory birds die from these glass curtain walls every year.
Frame-supported glass curtain wall is a glass curtain wall supported by the metal frame around the glass panel, which mainly includes:
1, open frame glass curtain wall
Open-frame glass curtain wall is a kind of glass curtain wall with exposed metal frame members on its outer surface. It takes the aluminum alloy profile with special section as the frame, and the glass panel is completely embedded in the groove of the profile. It is characterized in that the aluminum alloy profile itself has dual functions of skeleton structure and glass fixing.
Open-frame glass curtain wall is the most traditional form, which is widely used and has reliable working performance. Compared with hidden frame glass curtain wall, it is easier to meet the requirements of construction technology.
2. Hidden frame glass curtain wall
The metal frame of the hidden frame glass curtain wall is hidden on the back of the glass, and the metal frame can't be seen outdoors. Hidden frame glass curtain wall can be divided into full hidden frame glass curtain wall and semi-hidden frame glass curtain wall, which can be horizontal or vertical. The structural characteristics of the concealed frame glass curtain wall are: the glass is outside the aluminum frame, and the glass and the aluminum frame are bonded with silicone structural sealant. The load of curtain wall is mainly borne by sealant.
