The report on "Beijing Haze" is endless. How to return the safety and comfort of students' movements has become a concern of many school builders.
At the Shunyi International School in Beijing, the New York Times and Los Angeles Times paid attention to and reported on the construction of a film stadium that can filter PM2.5 and purify air at the end of last year. At the Bida 2017 Spring Summit, Mr. Liu Guomin of Bodwei Environmental Technology Co., Ltd. introduced the application and exploration of the film gymnasium in the school field.

Safe, intelligent and mobile gymnasium
The structural principle of a gas film building is actually very simple: it is a new form of construction formed by the "pressure difference between the inside and outside of the gas film."
The structure itself is very simple, but it takes some exploration and experience to make it safe, energy efficient, smart, clean and convenient.
This one is the effect picture of the film night scene.
This is the inside
First of all, I want to talk to everyone about security.
Buildings constructed with air pressure differentials are often questioned by many people.
We use our own patented technology: "Slanted Orthogonal Mesh Steel Cable System" to make such a tent-like film structure become a "resistant 16-level typhoon" that can "resist over more than 25KG of snow." Building mode." At the same time, the use of technical means to greatly enhance the durability of the film, extend the service life, and meet the North American permanent building code.
Through continuous research and development in technology, Bodwei “saving energy consumption by 70% every yearâ€: PVDF membrane, excellent self-cleaning performance, high SR/IE index, modular assembly construction, low carbon and environmental protection, membrane partition Good thermal performance, effectively reducing the internal energy loss of the film
"Full intelligent operation, remote monitoring of mobile APP". In this digital age, we also did some digital exploration in the use of the venue.
Through the various sensors in the venue, the stadium's data, such as air quality, venue pressure and other parameters are sent to mobile phones and other equipment, so that users can understand the health status and use of their stadium in any place.
In addition, compared with traditional sports venues, the film-building stadium has a weight of about 3 kilograms per square meter, which constitutes the architectural membrane of the whole building, and has a detachable and reusable point. There are also many advantages:
For example, the cost is low, only one-third of the cost of traditional stadiums;
The construction period is short, and the installation of the main membrane building can be completed in only 10 days;
Energy saving and environmental protection, the membrane is a very good thermal insulation material.
At the same time, due to the adoption of the three-layer transparent film, the heat insulation coefficient is increased and the natural light energy can be ensured to enter the hall. The gas film gymnasium can be insulated and light-transmitted. Under normal daylight conditions, artificial lighting is not required in the venue. Greatly reduce the energy cost of the venue in terms of lighting, heating, air conditioning and so on.
According to the energy consumption tracking statistics of the air film stadiums in Beijing, the air-conditioning and heating energy consumption of the film gymnasium is 1/4-1/10 of that of the traditional gymnasium. At the same time, the film gymnasium can be almost maintenance-free, which greatly reduces the maintenance cost of the gymnasium. Electromechanical equipment can be moved, transferred and transported very conveniently.
Stadium that can filter PM2.5
"Suddenly open" is the first feeling that many people have entered the Shunyi International School Comprehensive Gymnasium.
This is a stadium with an area of ​​4,271 square meters (75.6 meters long and 56.5 meters wide). It is also the largest air-film stadium in China. The ceiling is nearly 20 meters high.
Natural light enters the pavilion through the membrane, and the entire stadium is very light and the space is very large.
In this comprehensive stadium there is a football field with artificial turf. More than a dozen children from all over the world are playing on the football field, and there is a large multi-purpose stadium and runway. The tennis hall next to it is also 4271 square meters and there are 6 tennis courts in the hall.
"In addition to the energy-saving, constant-temperature and comfortable features, the two air-film gymnasiums in Shunyi International School also have the function of purifying the air and solving the PM2.5 problem that people are most concerned about nowadays."
According to Mr. Liu Guomin, Shenzhen Bodwei Construction Technology Co., Ltd., who is responsible for the construction of the venue, Shunyi International School attaches a high degree of attention to sports. According to the American standards adopted by the school, if the air pollution index exceeds 200, Students cannot go outside to participate in sports activities.
According to the statistics of this school, there were more than 40 days in 2012, and the children “cannot go outdoors to participate in sports activities because of air pollutionâ€. This situation is “it is difficult for schools and students to accept and acceptâ€.
In order to completely solve this problem, Shunyi International School chose the film gymnasium built by Shenzhen Bodwei Company.
The Film and Space Gymnasium is a high-tech emerging stadium. It is made of special architectural membranes and is equipped with a set of fully automatic intelligent electromechanical equipment to provide fresh air inside the completely enclosed membrane building, while controlling the interior. Temperature, humidity, pressure, etc., so that the inside of the film field stadium always maintains a positive pressure on the external environment, and a building structure system that supports the building body by the internal and external pressure difference.
It is precisely because of the special structural characteristics of the film gymnasium, that is to say, the air pressure in the film gym is higher than the air pressure outside the stadium, which ensures that the outside polluted air cannot enter the film hall through the doors, windows and gaps.
The only way for air to enter the film gym is the inflatable mechanical unit. As long as this link can be handled, the air in the film gym can be cleaned.
According to the requirements of the school, the R&D team did a lot of research and development work, and adopted patented technology, adding five air treatment processes to completely solve the problem of PM2.5.
After the completion of the project, Shunyi International School used the US instruments to measure the air quality in the film gymnasium. In the case that the outdoor pollution index has reached severe pollution (PM2.5 index is 650), the film theater The index is only 20.
In this way, students can breathe fresh, pollution-free air regardless of the air conditions, and can exercise in such an environment.
The pneumatic Standing Desk is a simplification of the automatic lifting table. It eliminates the need for a motor or compressor, and adjusts the air pressure bar manually to achieve the function of lifting
advantage:1. Low price and high cost performance 2. No need to connect to electricity, no oil, good safety.
Disadvantages:1. The stability is not high 2. It takes a little effort to raise and lower, and some buttons need to be lifted by hand to achieve the purpose of up and down.
