Definition of Glass Curtain Wall Glass Curtain Wall Construction Process

Vacuum glass can be used for curtain walls. Glass curtain wall is a beautiful and novel building wall decoration method, which is a distinctive feature of modern high-rise buildings. The glass curtain wall looks good from the outside, and from the inside, it has a wide field of vision. In the winter, it increases sunlight radiation and raises the indoor temperature. The curtain wall is not only simple in shape, luxurious and modern, it can reflect the surrounding scenery and has a very good decorative effect. It also integrates the wall and the window, which greatly reduces the weight of the building. With light weight, decorative, easy installation and construction advantages. Let's take a look at the definition of the glass curtain wall and the order of the construction technology of the glass curtain wall.

Definition of glass curtain wall

Definition: The glass curtain wall composed of the panel and glass rib or point support device and support structure is a full glass curtain wall.

Features: 1, the effect of transparency, can make the natural harmony of indoor space and outdoor environment.

2. The components are exquisite, the structure is beautiful, and the perfect fusion of exquisite metal structure and glass decoration art is realized.

3, supporting a variety of structures to meet the needs of different architectural structures and decorative effects.

4. The glass and connecting claws are connected by ball joints, which have strong ability of absorbing deformation.

Glass curtain wall function

The glass curtain wall of a modern high-rise building incorporates a combination of mirror glass and normal glass, filled with dry glass or inert gas. Hollow glass is divided into two layers and three layers. Two layers of hollow glass are sealed by two layers of glass and form a sandwich space. Three layers of glass are two layers of three layers of glass. Hollow glass has the advantages of sound insulation, heat insulation, anti-frost, moisture resistance, and strong wind pressure resistance. According to measurements, when the outdoor temperature is -10°C, the temperature in front of the single-layered glass window is -2°C, while the indoor temperature using the triple-layered insulating glass is 13°C. In the hot summer, double-glazing can block 90% of solar radiant heat. The sun can still pass through the glass walls, but most of the sun does not feel hot. The use of hollow glass curtain walls can make it cool in winter and cool in summer and greatly improve the living environment.

Glass curtain wall construction process

The installation sequence of glass curtain wall: construction preparation → measurement and pay off line → installation and treatment of embedded parts → installation of connection angles → installation of column columns → installation of cross beams → manufacture and installation of structural glass assembly components → caulking of weather-resistant silicone sealant → cleaning inspection → completion acceptance.

Selection of glass curtain wall

1, see the design requirements

1) The drawings should be complete and detailed, and the expression should be standardized. The description of construction drawings and requirements for construction, calculation of joints, calculation of anchorages of embedded parts, calculation of stress and deformation of curtain wall keel frame under vertical load and horizontal load, and lightning protection, fire prevention, and drainage prevention must be complete.

2) The curtain wall design should take measures against the leakage performance of rainwater. The cross-section form of the columns and beams of the glass curtain wall should be designed according to the isobaric principle. The leakage holes that flow to the outside should be set at the parts that are prone to leakage, and the condensation holes are easy to generate. Condensate discharge pipe shall be provided for the water part. When the component is manufactured, the water hole shall be drilled in strict accordance with the requirements. The sealing material of the opening part shall be neoprene rubber or silicon rubber.

3) The contact area of different metal materials on the glass curtain wall should be provided with insulating gasket (general thickness lmm) or other anti-corrosion measures. The size of the insulating sheet is not smaller than the contact area to ensure that the aluminum alloy column and the different steel connecting parts are in direct contact with each other. Contact pads should be set with flexible gaskets.

2, the choice of materials.

1) The profile for curtain wall should meet the high precision requirement as specified in the current national standard "aluminum alloy construction profile" GB/T5237. The thickness of the anodized film should not be lower than the "aluminum and aluminum alloy anodized anodic oxide film general specification" The grade of AA15 specified in GB8013 is as follows: The wall thickness of structural profiles is not less than 3mm. The minimum average film thickness is 15 дm and the minimum local film thickness is 12 дm. The surface color of the anodized aluminum alloy profile is basically uniform, and defects such as corrosion spots, electric welding, black spots, and oxide film fallout are not allowed.

2) Frame glass curtain wall should adopt safety glass. The glass curtain wall supported by the glass ribs shall be used for the glass curtain wall. The glass ribs shall be made of toughened glass. Personnel mobility density, public places where young people or young children are active, and all places that are vulnerable to impact in use should be made of safety glass.

3, physical performance testing

The physical performance test of the building curtain wall refers to the test of the wind wall deformation performance of the curtain wall, the leakage performance of the curtain wall rain, the air permeability of the curtain wall, the displacement performance of the curtain wall level, and many other physical properties. The unit curtain wall and the multi-span continuous beam curtain wall should have Representative parts of more than two layers of test specimens were tested. Structural adhesives, weatherproof adhesives and other materials used for curtain walls shall be tested in accordance with regulations before use, and shall be carried out before the installation of curtain wall components. Through the inspection, defects in the design and production process and problems to be noted in the installation process can be found, and the correctness of the design and material selection and the function of the curtain wall design are conformed to the actual situation.

Editor's summary: The relevant information on the definition of glass curtain wall and the construction technology of glass curtain wall was introduced here for everyone.
