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.

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.
