The current demand for large stands must meet the needs of the audience with a wide field of vision, protect them from environmental interference, and be beautiful, so the stand membrane structure began to come out. So what is the form of the stand membrane structure? SIGMA GROUP will explain it, I hope it can be helpful to everyone.                            

1. Stand skeleton membrane structure:

After the roof skeleton is made of steel or laminate, the structure of the membrane material extends over it to increase the stability of the underlying support structure. Due to the relatively simple shape of the roof, it is not easy to restrict openings. And it has the characteristics of high economic efficiency and can be widely used in large and small spaces.

2. Stand inflatable membrane structure:

Inflatable membrane structures are used to secure the membrane material around the roof structure. After using the air supply system to increase the indoor air pressure to a certain pressure, the ceiling will generate a pressure difference between the inside and outside to withstand the external force. Stands and steel cables are used as auxiliary materials, and there are no beams and columns to support. This gives you more space, faster construction and better economics, but you need to keep the blower running 24 hours a day, which is more expensive for continuous operation and machine maintenance.

3. Stand tensioned membrane structure:

It is composed of membrane material, steel cable and column. Steel cables and columns are used to introduce tension into the membrane material to obtain a stable shape. In addition to the practical, innovative, novel and beautiful shape, it can also represent the structural form of the spirit of the membrane structure.

In recent years, steel cables and compressed materials have been used to form steel cable nets in large-span spaces to support the top membrane material. Due to the higher requirements for structural accuracy, structural performance and expressiveness, its cost is slightly higher than that of the skeleton membrane structure.
