What is inflatable membrane structure?
Inflatable membrane structure is a new building structure and an important branch of light space structure. It has colorful shapes and superior architectural and structural characteristics. It is mainly divided into tension membrane structure, skeleton membrane structure, inflatable membrane structure and cable truss membrane structure. Inflatable membrane structure is a relatively closed space structure. Different from the traditional space structure building, it blows air into the structure through the fan to keep a certain pressure difference between the inside and outside of the membrane structure, thus ensuring the rigidity of the membrane structure system and maintaining the designed shape. At the same time, the pressure control system can maintain a certain internal and external pressure of the structure and ensure the stability of the structure. 19 17, W. Lanchester of England invented an inflatable membrane structure as the roof of the right outer courtyard building, which is a convenient and economical roof system, but he did not build it himself. 1946, Englishman WalterBird built the first modern inflatable membrane structure-Doppler radar dome, with a diameter of 15m and a rise of18.3m. The membrane material is neoprene and covered with glass fiber. From 1950 to 1970, the United States, Germany and other places have built a large number of similar domes with the maximum diameter of 60 m. 1970 World Expo Osaka, Japan provided an opportunity for the development of membrane structures. Because there are many earthquakes in Japan, the exhibition halls are mostly located in low-grade soft soil, so light structural system should be adopted. The structural design of the USA Pavilion was completed by DavidGeiger, and a large-span and low-profile inflatable membrane structure with a plane of 139m×78m was built for the first time.
From 1972 to 1984, seven giant inflatable membrane structures, such as Silver Dome, were designed by DavidGeiger and built by Birdair Company of the United States. However, most membrane structures have proved to be difficult to effectively resist harsh weather conditions. 1988, Japan built the Tokyo Dome. Although the inflatable membrane structure technology has reached a new level, since then, no huge inflatable membrane structure buildings have been built around the world.
What are the advantages of inflatable membrane structure?
The construction period is shorter than other buildings: all the design and production of the membrane in the gas model building are completed in the factory, and only the installation is carried out on site. The construction difficulty is low, and the construction period is shortened by over 1/2. It is the most economical building form often used in construction management. Pollution-free during construction: there is no noise, environmental pollution and construction waste during the production and construction of membrane materials. Inflatable membrane structure building can obtain large building space with little resource consumption. Lower cost: In traditional buildings, the larger the span, the larger the steel beam and the higher the cost. Inflatable membrane buildings are different. Within the scope allowed by the design, the span and cost have not changed, so the total cost is generally only 1/3 to 1/5 of the traditional steel structure and concrete structure. Lightweight building space with larger span: Due to the light weight of the membrane itself, the weight of the inner and outer double-layer membrane is less than three kilograms. By using the high pressure difference between indoor and outdoor inflatable membranes, 100 meter long span, large space and no beam and column can be realized; This is something that traditional architecture cannot do.
Does the inflatable membrane structure greenhouse belong to buildings and structures?
Inflatable membrane structure greenhouse belongs to buildings and structures.
Inflatable structure, also known as "inflatable membrane structure", refers to the building structure formed by filling air into film products made of polymer materials. inflatable
Structure can be divided into air-bearing membrane structure and inflatable membrane structure. The most typical inflatable membrane structure building is the Water Cube. The inflatable membrane structure on the inner and outer facades of the Water Cube consists of 3,065 air pillows, with a maximum of 70 square meters, covering an area of 654.38+10,000 square meters and a developed area of 260,000 square meters. It is the largest inflatable membrane structure project in the world, and it is also the only large public building completely enclosed by membrane structure.
The difference between architecture and structure
Buildings are generally called buildings. Generally refers to houses or places for people to carry out production, life or other activities. Such as industrial buildings, civil buildings, agricultural buildings and garden buildings.
Structures generally refer to places where people do not directly carry out production and living activities. Such as water towers, chimneys, trestles, dams and reservoirs.
Usually, the so-called structures refer to artificial structures that do not have, contain or provide human habitation functions, such as water towers, pools, filter pools, clarifiers and biogas digesters. Generally, man-made buildings that own, contain or provide human habitation functions are called buildings.
What are the advantages of inflatable membrane structure?
The inflatable membrane structure is very economical in use. Through the design of the film, the brightness of sunlight can be fully utilized during the day without supplementary light. At night, the efficient and energy-saving patented secondary diffuse reflection lighting system can effectively save lighting energy consumption.
The inflatable membrane structure is formed into a complex curved surface, which is beneficial to resist wind and snow.
Inflatable membrane structure has incomparable advantages over traditional building structures. Its outstanding environmental protection characteristics, high energy efficiency, super-mass, high intelligent monitoring system, low cost beyond imagination, unusual operation economy and fully enclosed structural design show its great attraction as a new building structure with humanization, convenience and economy.
