What issues should be paid attention to during the construction of membrane structures? Today, let is invite a membrane structure manufacturer to share what they typically focus on during construction.
The membrane surface should only be installed after the paint on the supporting structure components has dried to prevent the membrane from adhering to the supports due to wet paint, getting contaminated, or even tearing from localized stress concentration caused by adhesion.
When hoisting or lifting the membrane, extra care must be taken to avoid scratches or cuts from sharp objects. Any protruding parts that might come into contact with the membrane during lifting should be wrapped with soft materials for protection.
During hoisting, ensure even stress distribution across the membrane. If necessary, continuous "hoisting loops" can be welded onto the membrane, and these loops can be clamped between two steel plates for lifting. When welding the "hoisting loops," pay attention to the welding direction to ensure the weld is under tension during lifting and avoid peel stress on the weld.
The movement during hoisting should be slow and steady, with workers assisting from different angles using ropes to control the membrane is motion. Large-area membrane hoisting should be conducted on clear, windless days. According to China is membrane structure technical regulations, which came into effect on August 1, 2004, installation should not proceed when wind speeds exceed level 3 or temperatures are below. Mechanical equipment should be used for hoisting whenever possible. If manual lifting is necessary, minimize folding and squeezing of the membrane to avoid creases.
Once the membrane is hoisted into position, secure the edges and corners promptly. If tensioning cannot be completed on the same day, appropriate safety measures must be taken to prevent membrane tearing due to strong winds or rainwater accumulation overnight.
The entire installation process must strictly follow the construction design to ensure orderly execution. Supervisors should frequently inspect the entire membrane surface and closely monitor stress conditions to prevent accidents caused by localized stress concentration or over-tensioning. For high-altitude work, ensure personal safety at all times.
