What is a glass curtain wall? What are the classifications of glass curtain walls?

We know that glass is widely used in our daily life, and most of the curtain walls in our impression are cloth or electronic screens. Many people may have heard of the glass curtain wall, but they don't know much about it. So, what is a glass curtain wall? What does it do? What are the classifications of glass curtain walls? Now Bian Xiao will introduce you to what is the glass curtain wall and its classification, hoping to help you understand the glass curtain wall.

What is a glass curtain wall?

Reflectionglasscurtainwall refers to the external protective structure or decorative structure of a building, which can be displaced relative to the main structure through the supporting structure system without sharing 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.

What are the classifications of glass curtain walls?

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, flat and vertical, or criss-crossed. 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.

3. Point glass curtain wall

Point glass curtain wall is a new type of support in recent years. Point glass curtain wall, whose full name is point glass curtain wall with metal support structure, has developed rapidly in the city once it appears.

According to the different supporting structure, point glass curtain wall can be divided into the following types in form:

(1) Point glass curtain wall with metal supporting structure. This is the most widely used form at present. It uses metal materials as the supporting structure system, and the glass is firmly fixed on it through metal connectors and fasteners, which is very safe and reliable. Make full use of the flexibility of metal structure to meet the needs of architectural modeling, and people can clearly see the whole structural system supporting the glass through the glass. Crystal clear glass and solid metal structure are the embodiment of "beauty" and "strength". Enhance the contrast between "virtual" and "real".

(2) Point glass curtain wall with all-glass structure. It connects the glass supporting structure (glass rib) and the facade glass into a whole through metal connectors and fasteners, and becomes the building envelope structure. The construction is simple, the cost is low, the glass surface and ribs form a wide field of vision, which is pleasing to the eye, and the indoor and outdoor space of the building achieves the maximum visual integration.

(3) Point glass curtain wall with tie rod (cable) structure. It adopt stainless steel tie rods or cable corresponding to glass panes as that supporting structure of the curtain wall. The glass is fixed on it by metal connectors. In architecture, the precision of machining is fully realized, so that all components are tensile components. Therefore, prestress should be applied during construction, which can reduce the breakage rate of glass during vibration.
