The initial average formal analysis is called form finding analysis. For example, due to the common Membrane structure parking shed There is no bending stiffness for the raw material of, and the main shear strength is very poor. It is necessary to improve its stiffness and stability through the curvature transformation of the membrane surface and the lower prestress. The membrane structure shed has no stress free form at any time, so the membrane surface form must meet the stress learning average under certain boundary conditions and certain prestress conditions, and load analysis and shear analysis are carried out on this basis.
The substrate of the film structure greenhouse is divided into cold rolled substrate, hot galvanized substrate and electro galvanized substrate. This kind of color steel plate is often used to press the rollers of various brands of color steel equipment. The coatings can be divided into polyester, silicon modified polyester, vinylidene fluoride and plastisol. The surface morphology of membrane structure can be divided into coated board, embossed board and printed board. Membrane structure greenhouses are mainly used in private educational institutions, stadiums, parking lots and other places. Membrane structure greenhouses are still gradually replacing other old greenhouses as the first choice of greenhouses.
In order to ensure that the processing and production parts of the membrane structure shed should be horizontal, the processing environment should meet specific temperature and humidity requirements. Please dry the film table and don't stain it.
Completely different things are obviously different in design and manufacturing process.
Film processing must be carried out in strict accordance with the design drawings and technical documents. The heat seal of the film and other manufacturing processes shall be cut by special equipment, and the relevant measuring instruments shall be qualified by metrological verification.
The same batch of membrane materials shall be used for the membrane structure parking lot. The surface of the paint film shall be free of pinholes, obvious wrinkles, obvious dirt, broken wires, damages, and obvious color difference.
