With the acceleration of the pace of urban modernization, cars have become an indispensable means of transportation in any city. Because of the rapid development of the automobile industry in China, the number of cars in cities has doubled, but the urban construction planning has not been able to adapt to the requirements of this development as soon as possible, often without parking space. Therefore, the parking lot should be fully considered in the planning of the construction group. The construction and planning of the parking lot as an important part of the modern urban construction planning has become increasingly important. In the construction of many parking lots, the air dome structure shed stands out and becomes the darling of the construction industry. It is precisely because the application is so extensive that people are very popular, so special attention should be paid to the quality of construction and other aspects, Let the editor of Gaoshan Air Dome Structure Company explain how to ensure its quality.

The air dome structure is favored by people because of its advantages such as free and lightweight shape, flame retardant, easy to make, fast installation, energy saving, easy to use, and safe use. People can see the smooth air dome structure building with unique shape, and the wrinkles of the membrane material have an important impact on the membrane structure car shed. The wrinkling of the membrane structure car shed refers to the out-of-plane deformation of the membrane material under uniaxial tensile stress. The wrinkles on the membrane surface can be divided into two types: one is caused by the relaxation of the membrane material due to the loss of tension on the membrane surface in one direction, which is called structural wrinkles; The other is caused by defects in the film production process, improper heat sealing or improper packaging folding, which is called material folding.

Structural wrinkles are temporary and will disappear with the membrane surface being tensioned again, while material wrinkles will not disappear. Generally speaking, the fold refers to the former, namely structural fold. The effect of wrinkles on the air dome structure is not only reflected in the visual effect, but also can not be ignored. The appearance of wrinkles will lead to the redistribution of membrane surface pretension, so that the stress in some areas of the membrane surface is lower than the design value, while the stress in other areas is higher than the design value. When the membrane surface stress is lower than the design value, the local stiffness of the structure will be reduced, and the breeze vibration will easily occur; When the membrane surface stress is higher than the design value, it will lead to large strain and creep of the membrane material, and even local tear of the membrane material. In addition, wrinkles will also affect the beauty and drainage performance of the structure; Therefore, it is necessary to avoid the wrinkling of membrane material under normal service condition (long-term load combination).
