The tensioned membrane structure relies on the tension stress of the membrane itself, the support rod and the cable to form a mechanism system. Under the sunlight, the interior of the building covered by the film is filled with natural diffuse light, and the distinction between the light surface and the shadow without strong contrast, the indoor space visual environment is open and harmonious. At night, the lights in the building illuminate the night sky through the membrane of the roof, and the shape of the building shows a dreamlike effect. The tensioned membrane structure is especially suitable for the construction of the roof of the city's landmark buildings, such as sports and entertainment venues, shopping malls and restaurants that need advertising effect. The transportation hub of a city is the key building of the city's lifeline, and the use function requires the clear signs of each unit of the building. Thus in recent years, more and more such buildings use membrane structure. The service life of the building membrane material is more than 25 years. During use, the mechanical form of the material can be kept stable under the action of snow or wind load. Tracking tests and material loading and accelerated climate change tests prove that the mechanical properties and chemical stability indicators of its membrane materials have dropped by 20% to 30%, but they can still be used normally. The surface of the membrane is smooth and elastic, and the particles of dust and chemical substances in the atmosphere are extremely difficult to adhere to and penetrate. The building membrane can be restored to its original clean surface layer and light transmittance after being washed by rain.
