Modern High Rise Buildings Exterior Glass Curtain Wall System Cladding Construction

Product Description

A curtain wall is defined as a thin, usually aluminum-framed wall filled with glass.

The frame is attached to the structure of the building and does not bear the floor or roof load of the building.
Wind and gravity loads are transferred from the curtain wall to the building structure, usually at the floor line.

Curtain walls can be classified by their method of fabrication and installation into the following general categories:

1.stick systems 

2.unitized (also known as modular) systems.

Glass curtain wall is a new type of contemporary wall.

According to the different ways of glass curtain wall support structure, it will be divided into the following categories:

1, tie rod (cable) structure point glass curtain wall.
The use of stainless steel tie rods or with glass slit corresponding to the cable made of curtain wall support structure.
The glass is fixed by metal connectors with it. In the construction of full mechanical processing accuracy, so that the members are tensile rods.
Therefore, the construction to be pre-stressed, this flexible connection can reduce the rate of glass breakage when vibration.

2, metal support structure point type glass curtain wall.
Use metal materials to do the support structure system, through the metal connectors and fasteners will be firmly fixed on it, very safe and reliable.
Make full use of the flexibility of the metal structure to meet the needs of the building modeling, people can clearly see through the glass supporting the entire structural system of glass.

3,All-glass structure point-type glass curtain wall.
Through metal connectors and fasteners to the glass support structure (glass ribs) and the surface glass into a whole, become a building enclosure structure.

How to choose the design.

1,According to the requirements of the design

(1), the drawings should be complete and detailed, and the expression should be standardized.
Construction drawing descriptions and construction requirements, nodal pattern drawings, pre-buried anchorage node calculations, curtain wall keel frame in the vertical load, horizontal load under the action of stress deformation and other calculations, lightning protection, fire prevention, drainage measures must be complete.

(2), curtain wall design should be taken to prevent rain leakage performance measures, glass curtain wall column and beam cross-sectional form should be designed according to the principle of equal pressure, in parts prone to leakage should be set up to flow to the outdoor drainage holes, in parts prone to condensation should be set up condensate drainage pipes, the production of components in strict accordance with the requirements of the drilling of drainage holes, open part of the sealing material should be neoprene or silicone rubber products.

(3), the glass curtain wall should be set at the contact of different metal materials insulating gasket (general thickness lmm) or take other anti-corrosion measures, the size of the insulating sheet is not less than the contact area to ensure that the aluminum alloy column and different steel connectors direct contact, column and beam contact should be set at the flexible gasket.

In the glass curtain wall of modern high-rise buildings, the combination of low-e coated glass and ordinary glass, compartments filled with dry air insulating glass is used.
Insulating glass is a good heat insulation, sound insulation, anti-frost, moisture, wind pressure strength, beautiful and applicable, and can reduce the self-weight of the building of new building materials.
It is made of two (or three) pieces of glass, using a high-strength, high-gas-tight composite binder, the glass and the aluminum alloy frame containing the desiccant bonding, made of high-performance sound insulation and heat insulation glass.
According to experimental testing, in winter, when the outdoor temperature is -10 ℃, the temperature in front of the indoor single-layer glass window is -2 ℃, while the temperature in front of the insulating glass window is 13 ℃;.
And in the summer, double insulating glass can block 90% of the solar radiation heat; although the sun can still pass through the glass curtain wall, but the sun will not feel hot on the body.
Therefore, the use of insulating glass curtain wall room can be warm in winter and cool in summer, greatly improving the living environment.
