What s going on with the folds of the air dome building?

There are many reasons for wrinkles, but most of them are caused by improper prestress values in design and construction. The membrane is a kind of material with bending resistance and compressive stiffness approaching zero, and the membrane will not wrinkle when the shape finding analysis and load analysis are carried out in the design. Generally, for the anisotropic film material, when the principal strain in one direction is negative, the membrane element will appear in a unidirectional pleated state or a fully pleated state.

The structure of the membrane is for you: there are two main folds of the air membrane building.

1. Material folds should be checked when the membrane is processed, once the membrane is found to be wrinkled, pay attention to distinguish, if the material is folded, it can not be processed. Because the material folds are irreversible.

2. Structural folds Structural folds are recoverable folds, which are generally generated by the disappearance of tension in a certain direction, and the folds can be eliminated by re-tensioning, so you don't have to worry too much.

Many people don't know what an air dome is, and when I introduce it to them, I will give him an analogy, the air dome is similar to a hot air balloon, and the shape is also like a magnified version of a hot air balloon building, and people can move around in it.

Someone told me that no, the air film is like a vegetable greenhouse.

Perhaps the vegetable greenhouse can better understand the basic shape of the air film, but the metaphor of the hot air balloon shows part of the principle of the air film: a membrane structure building supported by the principle of air pressure.

In fact, the air film is a new type of building with high technology content in the new era, which has a history of several decades abroad. In the 60s of the 20th century, after the completion of an air film building in North America, thousands of air film buildings have been built in the world, and most of them have been in use, and some have been used for more than 30 years. China has now begun to gradually promote the integration of this advantage in the air dome building.

The air film uses the building membrane as the "shell", and the "shell" is supported by the difference between the internal and external air pressure to form a building. Its mechanical supporting units include inflatable function, air conditioning and heating system, backup system, etc., and the entire "shell" is fixed and sealed by a special airtight aluminum groove anchoring system.

The shell is made of PVC membrane material for construction, which has strong tensile resistance, corrosion and weather resistance, and can operate normally at 40-60 degrees below or above zero, and the building interior is guaranteed to be at a suitable temperature of 20-24 degrees.

Therefore, the air dome building is not a simple temporary "greenhouse" similar to "inflatable toys" in our previous concept, but a new form of architecture, which is different from conventional buildings, but it has all the characteristics of conventional buildings, and it can also be a long-term building with a service life of up to 20-30 years.

Of course, it also has the flexibility that conventional buildings do not have, and can be made into a detachable seasonal building. The air dome building meets the load code of a conventional building.

In the seemingly simple concept of air film, there are many careful designs to meet different needs. For example, as a golf course, the lighting needs not to affect the vision of the player. Here, the light source first shines on the lampshade, and then the lampshade is reflected to the film, and then reflected down, through the secondary reflection, the whole venue is completely free of glare and shadows, and the lighting brightness adapts to the needs of the human eye, and it is also energy-saving.

Air membrane building is a building structure system that uses special building membrane materials as the shell and is equipped with a set of intelligent mechanical and electrical equipment to provide positive air pressure inside the air membrane building and support the main body of the building.

1. The air film relies on the difference between internal and external air pressure to support the whole building. Due to the flexibility of the material and the inherent effectiveness of the structure and the curved shape, there are no members subjected to bending, torsion and compression;

2. There is no need for any frame or beam and column support inside, and the span can reach 180 meters;

3. With the increase of atmospheric pressure, the oxygen content of the environment is increasing, so the air pressure difference inside and outside the air film will not only not have any adverse effects on the human body, but will help people engage in sports activities or physical work; Generally, the difference between the inside and outside air pressure is 250 Pa, which is about one atmosphere (equivalent to the air pressure difference between the first and ninth floors of a normal building).

Air membrane building is a building structure system that uses special building membrane materials as the shell and is equipped with a set of intelligent mechanical and electrical equipment to provide positive air pressure inside the air membrane building and support the main body of the building.

Shanghai Zhanji membrane structure has more than 10 years of design and construction experience, leading the industry, affordable and quality. He has an in-depth understanding of the membrane structure industry, and can meet the dual needs of customers for product novelty and practicality.

Air membrane building, also known as "air supported structure", is a building structure system that uses special building membrane material as the building shell and is equipped with a set of intelligent operation control system to provide air pressure for the interior of the completely closed air membrane building, so that the whole building always maintains positive pressure on the external environment, so as to support the main body of the building by the internal and external pressure difference.

There are three factors that form this structure: material, support, and circulation.

1.Membrane material is formed by a high-strength, flexible film material and a resin coating material fixed on both sides of the substrate. The high ductility combined with the heat resistance, stain repellency and light transmission provided by the coating makes the membrane material better able to adapt to weather changes.

2.The air pressure difference between the inside and outside of the air film building is usually 250pa-500pa, and the air pressure inside the air film building is higher than the air pressure outside the building, so that the outside air cannot enter the air film building through doors, windows and gaps, and the simple understanding is to blow up a balloon. Some people will worry that the air pressure inside the stadium is greater than the outside air pressure, and whether the internal activities will affect the students' bodies?

First of all, the air pressure difference of 250-500pa has no effect on the human body; Secondly, with the increase of air pressure, the oxygen content of the air is also in an increasing state, and the internal activity of the air film can enjoy more oxygen circulation. ”

3.In addition to the materials and support system, the interior of the air film building has a good air purification link, and the only channel of the building is the inflatable mechanical unit in the operation control system, and the air enters and purifies in the inflatable mechanical unit at the same time to ensure that the air entering the room is clean.

Shanghai Zhanji membrane structure for you: the life of the air membrane building is mainly related to the following factors.

1. Membrane. Generally, the membrane manufacturer will provide 15 years of free compensation for the quality assurance promise, that is, if the membrane shows aging and quality problems within 15 years, the membrane production unit will provide free quality service.

Membrane can be customized according to customer requirements: the relevant selection of membrane material and related use and quality requirements to be customized and produced, especially the external environment of the special region and environment, membrane manufacturers will carry out special processing and production according to customer requirements.

2. Machinery and equipment.

Mechanical equipment is the heart of the air film building, and the quality of the equipment determines the life of the air film building and the convenience of use. Wind cabinets and fans are generally free of protection for 30 years, so there is no need for manual service.

About 15-20 years or so, depending on your use.

Air membrane building refers to a building structure system that uses special building membrane materials as the shell and is equipped with a set of intelligent mechanical and electrical equipment to provide positive air pressure inside the air membrane building and support the main body of the building. Specifically, you can consult Jiangsu Weibo intelligent prefabricated inflatable membrane structure.

Zhanji membrane structure will answer for you:

The air membrane building adopts the sixth new building material - membrane material as the "shell" of the building, which is supplied by a set of intelligent mechanical and electrical equipment to the interior and forms positive pressure, and the "shell" is supported by the air pressure difference between indoor and outdoor to form the main body of the building, and the interior does not need any frame or beam support. In addition to the constant temperature throughout the year, it also has an all-weather air filtration system. The air dome hall has air supply outlets and air outlets, and the atmospheric pressure in the air dome is guaranteed to be constant at 250Pa, which is the most suitable for human movement, and the outdoor air compressor connected to the air supply outlet has an air filtration function.

Even in autumn and winter, when the haze is at its heaviest, the museum can always stay at about 10. In the cold winter and heat, the air dome can be used to maintain the temperature in the tube with relatively low energy consumption. Not only will you not have difficulty breathing, but you will inhale fresher air than the outside.

Therefore, it can achieve an anti-smog effect.
