The membrane structure is supported by columns and steel frames or tensioned by steel cables. It is composed of membrane materials, steel cables and pillars. Tension is introduced into the membrane materials by steel cables and pillars to achieve stability. In addition to practical, creative and beautiful modeling, it is also a structural way to show the spirit of membrane structure In large span space, steel cable net composed of steel cable and compressed material is often used to support the upper membrane material. The construction cost is slightly higher than that of skeleton membrane structure because of high construction precision requirements, strong structural functions and rich expressive force.
Inflatable membrane structure is to fix the membrane material around the roof structure, use the air supply system to raise the indoor air pressure to a certain pressure, so as to generate a pressure difference in the roof surface to resist external forces. Because the air pressure is used to support, and steel cables are used as auxiliary materials, without any beam or column support, it can get more space, convenient construction, and high economic benefits, However, it is necessary to keep the blower working for 24 hours, and the cost of continuous operation and machine maintenance is high. Membrane structure landscape
Membrane structure is a kind of space structure, which can withstand certain external loads and forms a stable surface by using high-strength flexible membrane materials to fully experience the tension and compression of other materials. It is free, light, soft, full of strength, flame retardant, easy to manufacture, easy to install, energy-saving, easy to use and other advantages, so it is widely used around the world.
The construction weight of membrane structure engineering is light: because of the information and structure selected for membrane structure, membrane structure engineering is a light structure, which is very light compared with other traditional construction structures.
Long construction life of membrane structure engineering: membrane structure buildings belong to semi construction. Now the early membrane structure construction has been used for more than 30 years in the world and is still in use. Its steel skeleton can be used for a long time only after anti-corrosion coating and timely maintenance. The membrane material used for construction is a kind of composite material with outstanding mechanical function, high strength and aging resistance. As long as the structure design is reasonable, the service life of membrane structure construction can be up to 50 years.
The membrane structure has good self-cleaning property: the surface of the membrane materials used for construction has no static electricity, and has no adsorption force to dust, so it is not easy to touch dust. Even if a little dust falls, it is easy to be removed by wind and rain. Therefore, membrane structure construction always appears in our vision with a bright and clean appearance.
