Membrane structure parking shed It is a new type of building that can be seen everywhere. Under direct use, it can better handle the parking problem and help the traffic area. And the membrane structure parking shed has its own characteristics. Sun protection, rain protection, snow protection, etc. It also includes fire prevention measures. The vehicle is well protected. I can understand several points about the protection measures.

A: PTFE and PVC membrane materials are selected. According to the test, when the temperature of membrane materials and harmful gases are in contact with fire, the fire resistance and combustion function of PTFE membrane are higher than those of PVC membrane, but PVC membrane forms an opening soon after heating, which is beneficial to the emission of smoke and heat. In addition, the CO2 and CO produced by PTFE membrane is at least twice as much as that of PVC membrane, so It is used for membrane structure, and the sealed membrane structure is better.

B: According to professional technology, some outstanding methods can be adopted to distinguish fire areas by adding "fire belts", that is, combustible materials can be used to distinguish parts of buildings. The building components and decorations in this area are all non combustible materials. This method can properly do a good job of fire prevention

C: Medium steel is coated with fireproof coating, which is stable and better. With the fireproof advantage of steel structure, it can not be affected by high temperature.

One kind of membrane material used in membrane structure is the membrane material with high strength and good flexibility. The fabric base material is divided into polyester fiber and glass fiber. The resins used as coating materials are polyvinyl chloride resin (PVC), silicone and polytetrafluoroethylene resin (PTFE), which are light, light, light and transparent; Ability to reflect, absorb and transmit natural light; It is nonflammable, nonflammable or flame retardant; It has the characteristics of durability, fire resistance, excellent air tightness, etc; The membrane material whose surface is treated with fluorine (coated with PVF or PVDF) has the advantages of non sticking and good self-cleaning function.
