Membrane structure parking shed What are the solutions to membrane wrinkles?
Folds on the membrane surface of the membrane structure parking shed refer to the out of plane or out of plane deformation of the membrane material under the uniaxial tensile stress. Generally speaking, they can be divided into two types. One is the relaxation of the membrane material caused by the disappearance of the membrane surface tension in one direction. This phenomenon is called structural wrinkles, and the other is due to defects in the film production process Material folding is caused by improper thermal bonding or improper package folding.
The effect of wrinkles on the structure and performance of the membrane structure parking shed cannot be ignored, which is not only reflected in the visual effect. The appearance of wrinkles will lead to the redistribution of the membrane surface pretension, making the stress in some areas of the membrane surface lower than the design value, while the stress in other areas higher than the design value.
When the membrane stress is higher than the design value, it will lead to greater strain and mutation, even the local tearing of the membrane, and wrinkles will also affect the beauty and drainage performance of the membrane structure. During the construction of the membrane structure, under the normal long-term load combination, wrinkles should be avoided as far as possible.
Material wrinkles rarely occur, generally due to the problems of membrane cloth manufacturers, which are difficult to solve the day after tomorrow. In actual production, the processing and installation of membrane structure is the main reason for affecting membrane structure wrinkles. Construction personnel should pay attention to this aspect, strengthen specific measures, reduce membrane wrinkles of membrane structure, and make the membrane structure beautiful.
The above is about solving the wrinkles on the membrane surface of the membrane structure parking shed. I hope this article can help you!
