From the structural methods can be roughly divided into skeleton type, tension type, inflatable membrane structure in three forms.

1. Frame Supported Structure
After the roof frame made of steel or glulam, the structure of the stretched film material above it, the lower support structure has high stability, the roof shape is relatively simple, the opening is not easily constrained, and the economic benefits are high. Suitable for any large and small space.

2. Tension Suspension Structure
It consists of membranes, steel cables and struts. Tension is introduced into the membrane using steel cables and struts to achieve a stable form. In addition to being creative, innovative and aesthetically pleasing, it is also the structural form that best represents the spirit of the membrane structure. In recent years, large-span spaces have also used steel cables and compression materials to support the upper membrane material. form. Due to the high requirements of construction accuracy, strong structural performance, and rich expressiveness, the cost is slightly higher than the skeleton membrane structure.

3. Inflatable membrane structure (Pneumatic Structure)
The inflatable membrane structure fixes the membrane material on the periphery of the roof structure and uses the air supply system to increase the pressure in the chamber to a certain pressure, so that the pressure difference between the inside and outside of the roof is generated to resist the external force. The pressure is used to support and the steel cable is used as an auxiliary material. Without any beams or column supports, more space is available, the construction is quick and the economic benefits are high, but it is necessary to maintain the operation of the blower for 24 hours, which is higher in the cost of continuous operation and machine maintenance costs.
  
Only the buildings that express the structural logic correctly are powerful and persuasive.” This sentence reveals the essence of the tensioned membrane structure. For tensioned membrane structures, any additional support and decoration is superfluous. The structure itself is In other words, modeling that is not in conformity with the structure is not possible, because such a film is not fluttering or lacks stability.The beauty of a tensioned film structure lies in its perfect combination of “force” and “shape”.

The basic elements of a tensioned membrane structure are usually: membranes, cables, and support structures (stems, arches, or other rigid members).

Membranes A new type of building material that has been recognized as the "sixth building material" after brick, stone, concrete, steel and wood. The membrane material itself cannot be pressed or bent, so it is necessary to introduce a proper pretension for the membrane structure to work properly. In addition, another important condition to ensure the normal operation of the membrane structure is to form reciprocal surfaces. In order to reduce the deformation of the structure, the traditional structure must increase the resistance of the structure; while the membrane structure disperses the load by changing the shape, so that the minimum internal force increases. When the membrane structure is deformed near the equilibrium position, two kinds of restoring force can be generated: one is caused by the geometric deformation; the other is caused by the material strain. Generally, the geometric stiffness is much larger than the elastic stiffness. Therefore, for each diaphragm to have good stiffness, a negative Gaussian surface should be formed as far as possible, ie, “high point” and “low point” are formed along the diagonal direction. The "high point" is usually provided by a mast, and perhaps for this reason, some literature also refers to the tensile membrane structure as a suspension membrane.

As the elastic boundary of the membrane material, the membrane is divided into a series of diaphragms, thereby reducing the free supporting length of the membrane and making the surface of the membrane easier to form a large curvature. According to the literature, the free support length of the membrane should not exceed 15 meters, and the coverage area of ​​the monolithic membrane should not exceed 500 square meters. In addition, another important role of the cable is to provide additional support for the support structure such as the mast, so as to ensure that the support structure does not collapse due to the damage of the membrane material.

The transparence of the hollow roof is a problem considered by many architectural centers because the light transmission is not good.
Darkness gives people a very depressed feeling. And now more and more people will choose structural roofing?

Membrane structure roof features:
 One: high lighting factor
1. The sunlight shining on the roof is transmitted into the room in diffuse light.
2. Look inside the roof to become a series of bright surfaces, whose intensity changes due to the relative position of the roof and the sun.
Change.
3. The daylighting coefficient of the indoor space of the membrane structure (ie, the ratio of the natural light level of indoor and outdoor surfaces)
Can be as high as 10%;
4, and traditional buildings, light can only enter the room from a limited light window, even on cloudy days, membrane structure room
The level of light inside can also meet the basic requirements of most activities.
  
Two: good color
1. Indoor activity personnel will have a good color perception of white or beige-colored membranes. These two color pairs can
See light has a characteristic of linear spectral transmission.
2. The transmission spectrum is related to the fiber and its characteristics, the thickness of the coating, and the additional surface layer.
  
Three: No glare
Because transmitted light and reflected light that enter the roof of the membrane structure are diffuse light, glare is unlikely to occur.
However, the placement of the glass lighting area and the shade should be taken into account to prevent direct light from causing glare.

Membrane structure is a brand-new building structure form, it integrates architecture, structural mechanics, fine chemical and materials science, computer technology as one, with high technical content. The surface can be arbitrarily changed according to the architect's design needs, combined with the overall environment, building a landmark image project.

Artistic
Give full play to the imagination of the architects and reflect the beauty of structural components.
Because the film has a certain light transmission, it can reduce the lighting intensity and time during the day and can save energy. At the same time, the gorgeous landscape formed by the nighttime lantern transmission can also achieve very good advertising and promotional benefits. The large dome membrane structure can fundamentally overcome the difficulties encountered by traditional structures in snoring (unsupported) buildings, creating a huge unobstructed viewing space and effectively increasing the space usage area.

Self-cleaning
Membrane construction uses protective membranes that allow the building to have a good self-cleaning effect while ensuring the service life of the building.

Shorter duration;
Membrane construction projects are processed and manufactured in the factory, which can reduce on-site construction time, avoid construction cross-cutting, and have shorter construction period compared to traditional construction projects.

Membrane structure awning is precisely because it has a lot of advantages, so let this development so rapid, so the obvious advantage of the membrane structure awning is:

Membrane Structure Awning Pieces 1. The changing supporting structure and flexible membrane material make the building model more diversified, novel and beautiful, at the same time, it embodies the beauty of the structure, and the color is rich. It can create a more free architectural shape and a richer architectural language. .

Second, better economic benefits

Membrane building roof weight is only 1/30 of the conventional steel roof, which reduces the cost of the wall and the foundation. At the same time, the unique architectural and nightscape effects of membrane construction have obvious "architectural recognizability" and commercial effects, and its price-benefit ratio is higher.

Third, shorter construction period

All the processing and production in the membrane engineering can be done in the factory according to the design, and only the installation work is performed at the site. It is almost twice as fast as traditional construction.

Fourth, lower energy consumption

The film material has high reflectivity and low light absorption, and has low thermal conductivity, which largely prevents solar energy from entering the room. In addition, the translucency of the film ensures a proper natural diffusely diffuse light illumination chamber.

Fifth, a greater span of architectural space

Due to its light weight, membrane buildings can eliminate the need for large span coverage of the internal support surface, which allows people to flexibly use and use the building space.

Sixth, the use of a wide area

From a climatic point of view, it applies to the vast area from Alaska to Saudi Arabia; from a range of perspective, it is probably as small as a single tent, a flower garden piece, and a large number of buildings covering tens of thousands of square meters; from the field There are not only awnings in the landscape, but also in the carports, stands, interiors, stadiums, and so on, so if you want to, you can do it.
