Metal tents have a certain weight because they all use metal supports, so they need a lot of manpower and it takes time to assemble and disassemble. Especially in the process of demolition, there are many unsafe factors, which may hurt yourself if you are not careful. In addition to this internal inflatable structure, an inflatable building called frame structure has been developed at present. The so-called frame inflatable building does not need to inflate the house, but inflates the beams, columns and arches in the house like bicycle tires. Do not use masonry, wood or steel and reinforced concrete as beams and columns. Once inflated, this kind of beam-column has good rigidity and is very strong. Finally, the "skeleton" built by inflatable beams and columns is covered with plastic sheets, glass fiber sheets and other film materials, and anchored to the ground with ropes, thus becoming an inflatable building. Its advantage is that it doesn't need to inflate the whole building, so it can reduce the cost of constantly replenishing gas and leak-proof equipment. The disadvantage is that it is not as simple and fast as internal expansion.
