How much do you know about the glass curtain wall?
The glass curtain wall uses an insulating glass filled with dry air between the compartments. The insulating glass has two layers and three layers. The two layers of insulating glass are sealed by two layers of glass to form a sandwich space. The three layers of glass are composed of three layers of glass and two interlayer spaces.
Insulating glass has the advantages of sound insulation, heat insulation, anti-frosting, moisture proof and high wind pressure resistance. In the summer, double-layer insulating glass can block 90% of solar radiant heat. The sun can still pass through the glass curtain wall, but most of the sun does not feel hot. The room with the insulated glass curtain wall can be warm in winter and cool in summer, which greatly improves the living environment.
Basic classification of glass curtain wall
1. Exposed frame glass curtain wall
The exposed frame glass curtain wall is the metal frame member is exposed on the outer surface. It is framed by a special section of aluminum alloy profile, and the glass panel is fully embedded in the groove of the profile. Its characteristic is that the aluminum alloy profile itself has the dual Function of the skeleton structure and the fixed glass.
The framed glass curtain wall is the most traditional form, with the widest application and reliable performance. Compared with the hidden frame glass curtain wall, it is easier to meet the construction technical level requirements.
2. hidden frame glass curtain wall
The metal frame of the hidden frame glass curtain wall is concealed on the back of the glass, and the metal frame is not visible outside. The hidden frame glass curtain wall can be divided into two types: full hidden frame glass curtain wall and semi-hidden frame glass curtain wall. The structural characteristics of the hidden frame glass curtain wall are: the glass is outside the aluminum frame, and the glass is bonded to the aluminum frame with a silicone structural sealant. The load on the curtain wall is mainly absorbed by the sealant.
3. All-glass curtain wall
The all-glass curtain wall is up of glass ribs and glass panels.
4. point supporting glass curtain wall
The point supporting glass curtain wall is composed of a glass panel, a point supporting device and a supporting structure. The support structure has glass rib support, single steel or steel pipe support, truss support and tension cable system support structure.
5. Unitized curtain wall
The unitized curtain wall refers to the building curtain wall which is made up of the complete wall structure of the wall panel and the supporting frame at the factory and is directly installed on the main structure. The unitized curtain wall can be mainly divided into: unit curtain wall and semi-unit curtain wall.
