Common classification of membrane structures

The construction industry has always been one of the mainstream industries in the moment. Understanding some of the knowledge of the construction industry has helped us a lot. Today we will talk about the membrane structure in the construction industry.

1. The spatial structure : this type of structure is particularly suitable for large stadiums, population corridors, essays, public recreation and entertainment plazas, exhibition venues, shopping centers and other fields.

2. The fabric material used in the tensile structure is a kind of film with high strength and flexibility; the center fabric substrate is divided into polyester fiber and glass fiber, and the resin used as the coating material is polyvinyl chloride. Resin (PVC), silicone and polytetrafluoroethylene resin (PTFE), which is light, flexible, small in thickness, light in weight, good in light transmission; reflective, absorbing and transmissive to natural light; it is non-combustible and flame retardant Or flame retardant; has durable, fireproof, airtight and other characteristics; the surface of the film treated with fluorine (coated PVF or PVDF), itself is not sticky, has a good self-cleaning performance.

3. The membrane structure can be divided into steel structure, tension structure and aerated structure according to its structural form; according to the characteristics of the membrane, it can be divided into permanent membrane structure (the membrane life can exceed 25 years), semi-permanent membrane structure (film The material has a service life of 10-15 years) and a temporary membrane structure (the membrane life is 3-5 years); according to the membrane composition, it can be divided into PVDF membrane, PTFE membrane and ETFE membrane.
