Membrane structure parking shed As one of the most common urban landscapes, it is usually outdoors and resistant to sunshine and rain all year round. Although the membrane material itself is UV resistant, we also need to do a good job in the external protection of the membrane material itself, so as to extend the service life of the membrane structure parking shed to a great extent. The membrane structure parking shed is mainly composed of membrane materials and steel structure skeleton, which is characterized by beautiful appearance, unique structure and long service life. With the increase of membrane structure in people's daily life, what environmental factors affect membrane structure?

1. Prepare for protection before hurricane. For example, close the doors and windows, check whether there is strong wind that will blow the flowerpot and other things, and eliminate the membrane structure and other dangerous factors. Lighting structure around the membrane structure.

2. The membrane structure usually uses cover plate screws to fix the pins to prevent accidents. Due to long-term vibration, the screws become loose and fall off. It is recommended to use connectors with no dangerous locks at places with high vibration frequencies (especially at gusset plates). The cotter pin is made of 304 or 316L stainless steel (galvanized carbon steel is very solid, naturally rustproof, and not dangerous).

3. Membrane fixing bolts, steel cables and other membrane components are easily loosened and corroded. After the completion of the membrane structure parking shed, the steel supports, cables, bolts, etc. shall be regularly maintained and inspected to see if the anti rust paint falls off and causes corrosion.

4. In some areas with large wind load, the gusset plate of membrane structure is in a state of vibration for a long time, and the pin fixing the gusset plate falls off.

5. In order to reduce the impact of corrosion on the membrane surface, the corrosion membrane surface shall be selected respectively, and membrane structure parking shed shall be set at the corrosion extension. At the edge of the membrane, consider the stress point of the tension, and properly strengthen the edge of the tension membrane.

6. Remember the problem of membrane surface flatness in the axle structure at the 2013 Hangzhou World Expo. The plane of the membrane is provided with 11 overflow ports. When the rainfall exceeds the overflow height and reaches a certain thickness, the rainwater will pass through. Discharge at overflow port. The specific orientation of the overflow port is less than 8% of the film surface gradient.

7. If there is slight corrosion, remove the corrosion layer first, and then conduct anti-corrosion treatment from scratch. If the connecting parts such as screws are corroded, they should be replaced as soon as possible. Membrane structure is a flexible structure with low stiffness and low natural frequency. It is easy to deform and vibrate under the action of external wind load. Therefore, the material selection of the membrane structure shed must be more careful.

At the same time, the membrane structure is also eroded by rainwater for a long time. Rain or acid rain damages the membrane structure. Most membrane structures can be waterproof, but some cheap membrane structures have poor acid resistance, discoloration or weak membrane protection.
