What is a building curtain wall? What is a curtain wall?

1. The concept of curtain wall: The building envelope structure composed of structural frame and inlaid plates, which does not bear the load and function of the main structure. Second, the development trend of curtain wall a, from bulky to lighter plates and structures (natural stone thickness 25mm, new materials up to the thinnest up to 1mm) b, less varieties and gradually move to more types of plates and richer colors (at present, there are nearly 60 kinds of plates such as stone, ceramic plates, glass-ceramic, high-pressure laminates, cement filament boards, glass, inorganic fiberglass, clay boards, metal plates, etc. Extend the life of the curtain wall (from closed curtain wall to open curtain wall) f. Environmental protection and energy saving (at present, the most commonly used in the European and American construction markets is the metal decorative insulation board, which is composed of colored painted aluminum-zinc alloy carved finish, polyurethane insulation layer and glass fiber cloth; Taking into account the functions of decoration and thermal insulation and energy saving, the topcoat will not fade for 10-15 years, and the overall service life can reach 45 years; 3. Classification of curtain wall:

1. Closed and open 2. The difference between the two: a. Neutral silicon copper weather-resistant sealant and foam rod are required for closed type, and open type does not need to be used b. Open is lower than closed type, with good waterproof effect, long life, and easy ventilation Fourth, the performance of curtain wall: 1. Wind pressure deformation 2. Rainwater leakage 3. Air infiltration 4. In-plane deformation 5. Thermal insulation 6. Thermal insulation 7. Impact resistance 5. The three advantages of curtain wall:

Beautiful, energy-saving, easy to maintain].

The curtain wall is the exterior wall enclosure of the building, which is not load-bearing, and is a lightweight wall with decorative effect commonly used in modern large and high-rise buildings. It is a building envelope structure composed of structural frame and inlaid panels, and does not bear the load and function of the main structure. Our common office buildings are generally glass curtain walls, and banks are generally stone curtain walls and aluminum panel curtain walls. ]

It is a glass curtain wall, which is an object of aluminum alloy frame inlaid with various glass exterior wall lighting and envelope structure. It is also divided into: open frame and hidden frame. ]

Building curtain wall is a building perimeter maintenance structure composed of metal structure and plates, and does not bear the load and function of the main structure. Building curtain wall is different from infill wall, it has the following characteristics; 1 It is a complete structural system composed of panels and supporting structures; 2. It can withstand large deformation in its own plane or has sufficient displacement capacity relative to the main structure; 3. It is an envelope structure that does not share the load and action of the main structure.

Curtain walls are usually composed of panels (glass, aluminum panels, stone slabs, ceramic panels, etc.) and supporting structures (aluminum beams, columns, steel structures, glass ribs, etc.) behind them. This façade system is supported on the main structure and usually encapsulates the main structure. Because there is a wide gap between the panels, and the connection between the panels and the beams and columns has the ability to move, the curtain wall can withstand a large deformation of 1 100 in the plane.

The curtain wall is the exterior decoration of the house].

To put it simply, curtain wall mainly refers to a kind of external decoration that is different from the interior decoration, the curtain wall is actually divided into indoor and outdoor, and at the same time, there is also a distinction between functional and decorative, and the common form of structural form (such as frame type and unit type), or the form of material distinction (glass curtain wall, metal curtain wall, stone curtain wall, ceramic plate curtain wall, etc.) is basically understood by everyone.

At this stage, the mainstream glass curtain wall structure.

In a word, curtain wall mostly refers to a kind of quiet decoration outside the wall, which is not load-bearing, and has a certain displacement capacity because of its structural characteristics.

The curtain wall itself is generally not less than 500 yuan per square meter. Some of the main groups include private owners, business owners, property owners, investment and renovation companies, renovation companies, general contractors, developers and so on.

The main functions of the curtain wall include fire prevention, energy saving, temperature insulation, sound insulation, aesthetics, etc., and these are also the main curtain wall inspection content, of course, the content of the inspection also includes structural safety, material standards, wind load measurement, lightning protection investigation, etc., these are for the safety of the curtain wall, the consideration of practicability, practicability and so on.

Of course, to go deeper, the benefits of curtain walls are not limited to functions and the like, but also have a lot of promotion effects on enhancing the value of buildings, building corporate image, and enhancing employee enthusiasm, so they are also more and more popular.

First, the curtain wall system lacks a clear system.

Building curtain wall. China has made great progress, some systems have reached or surpassed the level of foreign countries, and a large number of high-quality projects and high-tech projects have emerged. The curtain wall is composed of panels and structural systems (supporting devices and supporting structures), which can have a certain displacement capacity relative to the main structure or a certain deformation ability of itself, and do not bear the role of the main structure.

Curtain walls are divided into structural curtain walls, unitized curtain walls, and all-glass curtain walls according to their structures, and glass curtain walls are mainly divided according to different facing materials.

Metal curtain wall, stone curtain wall, ceramic plate curtain wall.

1) Glass curtain walls (structural curtain walls) are mainly divided into three categories.

Exposed glass curtain wall.

Exposed glass curtain wall is a glass curtain wall in which metal frame members are exposed on the outer surface. Exposed frame glass curtain wall is the most traditional form, the most widely used, and reliable working performance. Compared with the hidden frame glass curtain wall, it is easier to meet the requirements of construction technology.

Concealed frame glass curtain wall.

The metal frame of the concealed glass curtain wall is hidden behind 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.

Point glass curtain wall.

Point glass curtain wall is a new support method that has emerged in recent years. Point glass curtain wall, its full name is metal supporting structure, point glass curtain wall, but once it appeared, it developed rapidly in the city.

2) Metal curtain wall.

The metal curtain wall is generally composed of aluminum alloy veneer, titanium magnesium alloy plate, metal composite plate and other finishing materials, and is generally a civil building.

The application of Chinalco Laqing alloy veneer curtain wall is more common. According to its structural form, it can be divided into unit aluminum curtain wall and component aluminum curtain wall, the so-called unit curtain wall refers to the framed curtain wall that assembles the panel, beam and column into a curtain wall unit in the factory, and completes the installation and construction on site in the form of a curtain wall unit.

3) Stone curtain wall.

Stone curtain walls are usually composed of stone panels and supporting structures (beams, columns, steel structures, connectors, etc.), and are not responsible for the load and function of the main structure of the building envelope.

The structural form is divided into pin-pin structural form, short-groove stainless steel supporting plate structural form, long-groove aluminum alloy supporting plate structural form, hanging small unit structural form, and back-bolt connection structural form.

The definition of curtain wall: it is the outer wall enclosure of the building, which is not load-bearing and hangs like a curtain, so it is also called "curtain wall", which is a lightweight wall with decorative effect commonly used in modern large-scale and high-rise buildings.

It can also be understood as on the basis of the completion of the main structure frame, put on a layer of "beautiful coat", which has the functions of anti-wind pressure deformation, heat preservation, sound insulation, lightning protection, fire prevention, sound absorption, energy saving, and beautiful decoration. Compared with the traditional window wall building, the appearance changes are more diverse, the visual effect is more beautiful, and the energy-saving effect is also better.

According to the type of installation, it can be divided into: structured curtain wall and unitized curtain wall. According to the type of material, it can be divided into: glass curtain wall, stone curtain wall, metal plate curtain wall, man-made panel curtain wall and other styles, and with the progress of technology, the types of curtain walls are still increasing.

The curtain wall is the outer wall enclosure of the building, which is not load-bearing and hangs like a curtain, so it is also called "curtain wall", which is a lightweight wall with decorative effect commonly used in modern large-scale and high-rise buildings. It is a building envelope or decorative structure composed of panels and supporting structure systems, which can have a certain displacement capacity relative to the main structure or a certain deformation ability of itself and do not bear the role of the main structure (the external wall frame support system is also a kind of curtain wall system).

The curtain wall is the outer envelope of the building, including glass curtain wall, metal sheet curtain wall, stone curtain wall, etc.

Building curtain wall refers to the non-load-bearing exterior wall enclosure of the building, which is usually composed of panels (glass, metal plates, stone slabs, ceramic plates, etc.) and supporting structures (aluminum beams, columns, steel structures, glass ribs, etc.) behind it.

The building curtain wall is composed of a supporting structure system and panels, which can have a certain displacement capacity relative to the main structure and does not share the role of the main structure.

During the "Twelfth Five-Year Plan" period, China will vigorously develop building energy-saving related industries, and China will carry out energy-saving renovation of 100 million square meters of buildings, which is undoubtedly an opportunity for the rapid development of the building curtain wall industry.

After years of development, China's curtain wall industry has shown a rapid development trend in production and sales, and has become a major country in the production and use of curtain walls in the world. China produces and installs about 55 million square meters of various building curtain walls every year, with an annual output value of nearly 120 billion yuan, and the total market has accounted for more than 60% of the world's total.

Hello, I am glad to be able to ask you about your question, curtain wall is a kind of building exterior wall decoration material. The specific description is as follows: it refers to a kind of decorative wall on the surface of the exterior wall of the building, which is usually composed of aluminum alloy, glass, stone, metal plate and other materials.

The main function of the curtain wall is to beautify the appearance of the building, enhance the overall image of the building, and at the same time can also play the role of heat insulation, heat preservation, waterproof, windproof, sound insulation and so on. Curtain walls are widely used in high-rise buildings, commercial complexes, office buildings, hotels, hospitals, schools and other buildings. The design and construction of curtain walls need to consider many factors, such as architectural style, environmental conditions, material selection, safety protection, etc.

The material and structure of the curtain wall can also affect the overall cost and service life of the building. With the continuous progress of science and technology, the design and production technology of curtain wall is also developing, and more and more new materials and technologies are applied to the production of curtain wall, making the shape of curtain wall more diverse, beautiful, and intelligent.
