[China Glass Net] The glass curtain wall is composed of three parts: skeleton, glass and accessories.
(1) Skeleton. It consists of a longitudinal column and a crosspiece, which is used to support the glass, fix the glass, and connect to the wall structure through the connecting piece. It transmits the weight and wind load of the glass and other loads to the main structure, so that the glass and the wall structure are integrated.
Type 1 steel skeleton: The steel is used as the skeleton of the glass curtain wall. The glass is embedded in the frame of the aluminum alloy, and then the aluminum alloy frame and the skeleton are fixed. For the frame of the steel combination, the mesh size may be appropriately increased, but for the main bending member, the section should not be too small, and the deflection should be controlled within 5 mm. Otherwise it will affect the glass installation of the aluminum window and also the appearance of the curtain wall.
2 Aluminium alloy profiles (the term “profiles†are provided by the industry encyclopedia). Skeleton: The aluminum alloy profiles with special sections are used as the skeleton of the glass curtain wall. The glass is embedded in the groove of the skeleton, between the pillars of the glass curtain wall and the main structure. Secure with a connecting plate. When installing the glass, first place the aluminum alloy bead on the inside of the column, then place the glass into the groove and seal it with a sealing material. The beam supporting the glass is slightly inclined to exclude rainwater flowing into the groove due to poor sealing and to seal the outer cover.
(2) Glass is the key material for the construction of glass curtain walls. It directly restricts the performance of the curtain wall, and is also the main embodiment of the curtain wall art style. Therefore, the selection of glass is the main content of the curtain wall design. If the glass is improperly selected, it will have quite serious consequences. According to the application requirements, float glass, heat absorbing glass, tempered glass, heat reflective coated glass, low-emission coated glass, and laminated glass and insulating glass composed of these single-layer glasss are separately selected (interlayer hollow) Industry Encyclopedia provides) glass).
1 Float glass: The forming process of float glass production is done in a tin bath with protective gas (N2 and H2). The molten glass continuously flows from the kiln and floats on the surface of the relatively dense tin liquid. Under the action of gravity and surface tension, the molten glass spreads on the tin surface, flattens, and the upper and lower surfaces are flattened, hardened and cooled. After being introduced into the transition roller table. The roller of the roller table rotates, and the glass ribbon is pulled out of the tin bath into the annealing kiln, and after annealing and cutting, a flat glass product is obtained. Compared with other forming methods, the advantages of float method are: Suitable for high-efficiency manufacturing of high-quality flat panels (the term "flat" is provided by the industry). If there is no stratum, the thickness is uniform, the upper and lower surfaces are flat and parallel to each other; The scale is not limited by the forming method, the energy consumption per unit product is low; the utilization rate of the finished product is high; the scientific management and realization of the whole line mechanization and automation are realized, and the labor productivity is high; the continuous operation cycle can last for several years, which is favorable for stable production; It can provide suitable conditions for online production of some new varieties, such as electro-float reflective glass, sprayed film glass during annealing, and cold-end surface treatment.
2 Endothermic glass: Endothermic glass is a flat glass that absorbs a large amount of infrared radiation energy and maintains a high visible light transmittance. There are two methods for producing endothermic glass: one is to add a certain amount of colorant with endothermic properties to the raw material of ordinary soda lime silicate glass (the term "colorant" is provided by the industry encyclopedia); The seed is made by spraying one or more layers of metal or metal oxide film on the surface of the flat glass.
3 tempered glass: The mechanical strength of tempered glass is more than 3 times that of ordinary annealed glass. After breaking, it becomes a small obtuse angle granule, which will not cause significant harm to the human body. The bending strength is 3 to 4 times larger than that of ordinary glass. The temperature difference that can withstand is 2.5 to 3 times of annealed glass, it belongs to legal safety glass and has good thermal stability. It is widely used in places with high requirements on mechanical strength and safety.
4 Heat-reflecting coated glass is also called solar control film glass: it is formed on the surface of high-quality float glass by plating one or more layers of metal compound film. It can effectively control the direct radiation energy input of the sun, has a variety of reflective tones and excellent decorative effects, good indoor and architectural structure avoidance function, and has an ideal visible light transmittance (entry "through" The rate "provided by the industry encyclopedia" and reflectivity, can also reduce the transmission of ultraviolet light.
5 Low-emission coated glass: Low-emission coated glass (LOW-E glass) is formed by plating several layers of low-radiation materials and other metal compound films on the surface of high-quality float glass. The so-called "low radiation" is named because this coating layer has an extremely low surface emissivity (the term "emissivity" is provided by the industry encyclopedia). It blocks the amount of insulation from the hot end to the cold end. That is, in winter, the heat in the room is prevented from leaking to the outside, and in the summer, the outdoor heat is prevented from entering the room. It has a higher reflectivity for the infrared heat radiation from the sunlight and a higher transmittance for the visible light portion of the sunlight. LOW-E glass can achieve higher visible light transmittance and lower reflectivity, which can effectively avoid light pollution and improve indoor lighting. L0w-E glass must be used as insulating glass due to the protection of the film layer and the need to control heat transfer. Insulating glass made of LOW-E glass can simultaneously control direct sunlight radiation and greatly reduce the overall heat transfer coefficient of the glass. And LOW-E insulating glass is a good energy-saving glass product.
6 High-strength single-piece cesium-potassium fire-retardant glass: High-strength single-piece cesium-potassium fire-resistant glass is a high-strength and high-safety fire-proof glass that can be used for building exterior walls, and its strength is 15 times that of tempered glass. The broken particles are smaller than tempered glass, the fire resistance is up to 1h~3h, and the weather resistance is the same as that of ordinary float glass. Due to its safety and excellent fire performance, it has been widely used in engineering.
7 Laminated glass: Laminated glass is made of a tough polyvinyl butyral (PVB) interlayer film between glass, which is processed by high temperature and high pressure. Therefore, when the laminated glass is broken by the extraordinary external force, the glass fragments will adhere firmly to the PVB interlayer film, and there will be no sharp glass fragments falling off (the term "shedding" is provided by the industry encyclopedia) or pointing to the glass surface. This makes it almost impossible for people who come into contact with it (especially adolescents) to be scratched or bruised by broken glass (the term "broken glass" is provided by the industry's encyclopedia). The PVB film absorbs a large amount of impact energy and rapidly attenuates it. When the glazing ceiling, skylight, ceiling and overhead floor are made of laminated glass, even if the glass is broken, there is no smashing and falling. The PVB film hinders the sound waves, so that the laminated glass can effectively block the sound transmission and reduce the noise. Laminated glass has a very high barrier to UV light (up to 99%), helping to avoid the effects of UV radiation on valuable furniture curtains, displays or other items.
8 Insulating glass: Insulating glass is a glass component in which two or more pieces of glass are separated by a certain thickness of aluminum frame filled with high-efficiency molecular sieve adsorbent, and the edges are sealed and bonded with high-strength sealant. The air in the sealed glass space constitutes an insulation and noise barrier. If the space is filled with an inert gas, the heat insulation and sound insulation properties of the product can be further improved.
