With the progress of science and technology and the development of the construction industry, air membrane building, as a new form of construction, has gradually been widely used in various fields. Air membrane building has been widely recognized for its unique advantages, such as large span, light weight, energy saving and environmental protection. However, as a new form of construction, the safety and security of air dome buildings have also attracted much attention. This article will address the safety and security issues of air dome buildings and propose corresponding solutions.
1. Overview of air dome building.
Air membrane building is a kind of inflatable membrane structure building, which mainly uses air pressure to support the membrane surface, and realizes the expansion and retraction of the building by adjusting the air pressure. Air dome buildings are widely used in large venues, exhibition centers, industrial facilities and other fields. Due to its advantages of large span, light weight, energy saving and environmental protection, air membrane building has become an important form of modern architecture.
Second, the safety and security of air dome buildings.
Although the air dome building has many advantages, its safety and security still need to be paid attention to. Here are some possible security issues:
1.Aging of membranes.
The main structure of the air membrane building is composed of membrane materials, which will lead to the aging of membrane materials and the decline of strength and durability after long-term use. If the membrane is severely aged, it can cause safety issues.
2.Wind and snow load problems.
Air-dome buildings are usually in an open-air environment and must withstand the effects of natural factors such as wind and snow. If the wind and snow load is too large, it will cause damage to the air film and even cause safety accidents.
3.Fire safety issues.
The fire performance of the air membrane building is relatively poor, and once a fire occurs, the fire is easy to spread rapidly in the inflatable membrane. In addition, the air film material is prone to deformation and melting at high temperatures, leading to the collapse of the building.
4.Air pressure control issues.
The air pressure of the air dome building needs to be maintained within an appropriate range to ensure the stability and safety of the building. If the air pressure is not properly controlled, it may cause the membrane to crack or the building to deform.
3. Safety and security measures for air dome buildings.
In view of the above safety problems, the following measures can be taken to improve the safety of air dome buildings:
1.Choose high-quality membranes.
Choosing high-quality membrane materials is an important measure to ensure the safety of air membrane buildings. The selection of membrane materials with good durability and mechanical properties can extend the service life of the building and reduce the risk of aging. In addition, the membrane material is regularly inspected and maintained, and the damaged and aged parts are repaired in time to keep it in good working condition.
2.Improve the building's resistance to wind and snow.
In order to resist the influence of natural factors, corresponding measures can be taken during the design and construction of air dome buildings. For example, increase the wind resistance design of the building and improve the snow pressure resistance of the building. At the same time, strengthen quality supervision during the construction process to ensure that the construction quality meets the relevant standards.
3.Enhance the fire performance design of the building.
In view of the fire performance of air dome buildings, corresponding fire protection measures can be taken in the design stage. For example, flame retardant membranes or fire-retardant coatings can be added to improve the flame retardant properties of the material. In addition, a fire alarm system and fire extinguishing equipment are set up in the building so that fire sources can be identified and extinguished in a timely manner.
4.Establish a complete air pressure control system.
The stability and reliability of the air pressure control system is essential for the safety of the air dome building. A sound air pressure control system can ensure that the air pressure in the air film is kept within a proper range. By setting up sensors and automatic adjustment devices, changes in air pressure are monitored in real time and adjustments are made to prevent abnormal situations. At the same time, strengthen the daily maintenance and inspection of the system to ensure its normal operation.
