Answer: The membrane structure carport is composed of membrane, cable and supporting structure. The unstressed state has no rigidity. It is a mechanism rather than a structure and cannot withstand external loads. Therefore, the membrane structure carport needs to be prestressed. The greater the prestress, the greater the system stiffness. The larger the size, the higher the requirements for the support system and the support, and the higher the construction cost, so the prestress should be appropriate.
Question: How to ensure the quality of the membrane structure carport?
Answer: Static calculation must be carried out when designing, while ensuring the beautiful appearance, the stability of the overall structure should be ensured; welding quality should be ensured during processing, anti-corrosion treatment should be in place, film material cutting should be reasonable; supporting structure should be ensured when installing To be firmly connected, the membrane material must be in place to ensure that the prestress of the membrane surface meets the design requirements; during maintenance, sharp and hard objects scratch the membrane surface. The steel structure must not be adjusted or disassembled at will, and personnel should be arranged to drain water in extreme weather. , Discharge snow, and inspect the carport regularly.
Question: What is the cause of water accumulation in the membrane structure carport?
Answer: It is mainly caused by unreasonable design and improper construction. Because PVDF membrane has good ductility, if water accumulates somewhere on the membrane surface of the carport, it is easy to produce a depression, which will bear other directions. The collected rainwater produces a "bag-like effect". As the rainwater continues to accumulate, the accumulation of water will become more and more serious.
Question: What is the price of the membrane structure carport?
Answer: The price of the membrane structure carport is affected by many factors, such as the complexity of the model, the use of membrane materials, the size of the company selected, the area of the carport, etc. The calculation formula is: membrane structure carport price = steel consumption * unit price + membrane material used Area * unit price + labor fee + tax;
Question: What is the meaning of film cutting compensation value (shrinkage)?
Answer: The film material is cut in a stress-free state. The cutting model is the shape in the prestressed state, and the film material is an elastoplastic material. Therefore, to obtain the design form in the prestressed state, it must be done during film cutting. Compensation (shrinkage).
Question: What is the standard for the length of the steel cable?
Answer: The production length of the steel cable refers to the length in its prestressed state. Therefore, when the steel cable is manufactured, it should be calibrated under the design prestress and then relaxed for production.
Question: What is the relationship between the position when the steel structure is installed and the position after the prestress is applied?
Answer: Since the shape of the supporting structure will change after the prestress is applied, the influence of the prestress should be considered in the initial stage of the installation of the steel structure to achieve the design shape after the prestress is completed. The steel structure is designed with a graphic model, and the steel structure should be checked for strength, rigidity and stability.
