Australia AS Standard Certified Membrane Structural Building Construction

Australia AS standard Certified Membrane Structural Building Construction

Membrane structure is a space structure that uses high-strength flexible film materials to withstand the tension and compression of other materials to form a stable curved surface that can withstand a certain external load. Its shape is free, light, soft, full of power, flame retardant, easy to make, quick to install, energy saving, easy to use, safe to use, etc., which makes it widely used all over the world.
 
Specifications:

 
Membrane structure is a structural system that combines architecture and structure. It uses high-strength flexible film materials and auxiliary structures to generate certain pre-tension stresses in a certain way and form a certain spatial shape under stress control as a covering structure. Or the main body of the building, and a type of narrow structure with sufficient rigidity to resist external loads.
 
Membrane structure is a new type of building structure developed in the middle of the 20th century. It breaks the pattern of pure linear architectural style. With its unique beautiful curved shape, it is simple, crisp, rigid and soft, and the combination of strength and beauty. Refreshing feeling, while providing architectural designers with greater imagination and creative space. Membrane structure has a strong sense of time and representativeness. It is a multi-disciplinary cross-application project integrating architecture, structural mechanics, fine chemical engineering, material science, and computer technology. It has a high technical content and artistic appeal. Its curved surface Can be arbitrarily changed according to the architect's design needs. Combined with the overall environment, the iconic image project is built, with strong practicability and wide application fields. It can be applied to large public facilities, such as the roof system of stadiums, airport halls, exhibition centers, shopping centers, parking lots, platform facilities, etc.
 
Advantages:

Membrane structure engineering is light in weight: The materials and structure used in the membrane structure confirm that the membrane structure is a light structure, which is very light compared with other traditional building structures.

Membrane structure engineering has long service life: Membrane structure buildings are semi-permanent buildings. The earliest membrane structure building in the world has a history of more than 30 years and is still in use. Its steel frame can be used forever as long as it is coated with anti-corrosion and maintained in time. The membrane material used in construction is a kind of advanced composite material with good mechanical properties, high strength and aging resistance. As long as the structure design is reasonable, the safe service life of the membrane structure building can be as long as 50 years.

The membrane structure has good self-cleaning performance: the surface of the membrane material used in construction has no static electricity, and has no adsorption power to dust, so it is not easy to get dust, and even a little dust can be easily removed by wind and rain. Therefore, membrane structure buildings always appear in our vision with bright and clean surfaces.

The membrane structure has a large span: the membrane structure can be built into a large-span building without intermediate support columns. Some large-scale public event venues and stadiums require column-free, large-area open space indoors, which poses a big problem for architects. With a membrane structure roof, the problem is greatly simplified. Because the membrane per unit area is very light, the load-bearing capacity of the framework is greatly reduced. When necessary, a very light roof can be propped up by the slight pressure difference between indoor and outdoor air.

Membrane structure has good manufacturability: Membrane materials are flexible materials and some complex spatial curved surfaces that are difficult to manufacture with rigid materials. It is much more convenient to adopt membrane structures. The membrane material can be supported by the steel frame, or can be stretched by the rigging to generate various spatial curved surfaces. The curved surface generated by the membrane structure is smooth and soft, and it can clearly reflect the beauty of the membrane under pressure.

The construction period of the membrane structure is short: the production of the skeleton and the processing of the fabric are carried out in the factory, so the construction period on the site is greatly shortened, and the situation of cross-working and mutual interference of multiple types of work on the site is reduced.

Classification:
The architectural structure of the membrane structure is colorful and ever-changing. According to the support method, it is divided into an inflatable membrane structure, a tensile membrane structure and a skeleton support membrane structure.
1. Skeleton membrane structure
The roof skeleton made of steel structure or integrated material is stretched above the membrane structure, and the lower support structure has high stability. Due to the simple roof shape, the opening is not easy to be restricted, and it has high economic benefits. It is widely applicable For any large and small space.
2. Tensile membrane structure
It is composed of membrane material, steel cable and pillar, and uses steel cable and pillar to introduce tension into the membrane material to achieve a stable form. In addition to practicing creative, innovative and beautiful shapes, it is also the most structural form that can demonstrate the spirit of membrane structure. Large-span spaces also mostly use steel cables and compressed materials to form a steel wire mesh to support the upper membrane. Due to high construction accuracy requirements, strong structural performance, and rich expressive power, the construction cost is slightly higher than the skeleton membrane structure.
3. Inflatable membrane structure
The inflatable membrane structure is to fix the membrane material around the roof structure. After the indoor air pressure is raised to a certain pressure by the air supply system, the pressure difference between the inside and outside of the roof is generated to resist the external force. Because the air pressure is used for support, and the steel cable is used as an auxiliary material , Without any beam and column support, it can get more space, quick construction and high economic benefit, but it needs to maintain the 24-hour blower operation, which is higher in the cost of continuous operation and machine maintenance costs.
