Membrane structure parking shed What are the structural forms of?
The membrane structure shed has many advantages, such as light weight; Good shockproof and antifreeze performance; There is no need to apply internal support plates, etc., which not only reduces the difficulties encountered by residential building structures in long-span construction projects, but also can be transformed into larger open spaces. But many people still don't know much about the membrane structure shed. There are many structural forms of the membrane structure shed, and how many are there? The following is a short story to share with you. I hope it will be helpful to you.
From the structural form, the membrane structure shed can be roughly divided into three types: skeleton type, tension type and inflatable membrane structure. The inflatable membrane structure shed is the membrane material around the fixed roof structure. Use the air supply system to make the indoor air pressure rise to a certain pressure, and then generate a pressure difference inside and outside the roof to resist external forces. As the pneumatic support is adopted, the steel cable is used as the auxiliary material, without any beam and column support, and larger space can be obtained. The construction speed is fast and the economic benefit is high. However, it is necessary to maintain 24 hours of fan operation, and the cost of continuous operation and machine maintenance is high.
After the skeleton membrane structure shed, the roof skeleton is composed of steel structure or laminated materials, on which the membrane materials are stretched, and the lower support structure has high stability. Because the roof shape is relatively simple, the opening is not easily restricted, and the economic efficiency is high, this is also the reason why it is widely used in any size of space. Tension membrane structure is composed of membrane materials, steel cables and struts. Tension is introduced to membrane materials through steel cables and struts to achieve a stable form. In addition to practicing creative, innovative and beautiful modeling, it is also a structural form that can better reflect the spirit of membrane structure. In recent years, large-span space has also adopted the form of steel cable net composed of steel cables and compression materials to support the upper membrane materials.
