Characteristics of landscape film 1： Light weight
The reason why the dead weight of tensile structure is small is that it relies on the form of prestress rather than materials to maintain the stability of the structure. Therefore, its dead weight is far less than that of traditional building structures, but it has good stability. Architects can use its lightweight and long-span characteristics to design and organize the detailed components of the structure, organically unifying its lightweight and stable structural characteristics.
Landscape film characteristic II: light transmittance
Light transmittance is one of the most widely recognized characteristics of modern membrane structures. The light transmittance of the film material can provide the required light for buildings, which is of great significance for building energy conservation. This is particularly important for some commercial buildings that need more light and high brightness. Through the use of natural lighting and artificial lighting, the transmittance of film materials can provide more creative space for the design of buildings. At night, the transmittance turns the film structure into a sculpture of light.
The transmittance of the film material depends on its base fiber, coating and color. The spectral transmittance of standard membrane materials ranges from 10% to 20%. Some membrane materials can reach 40%, while some films are impermeable. The selection of light transmittance and light color of film material can be adjusted by the color of coating or surface layer. Through the proper combination of the film material and the transparent thermal insulation material, the multilayer film containing the thermal insulation layer can be made transparent. Even though the spectral transmittance is only a few percentage points, the film roof is still bright and transparent to the eyes of people.
Feature 3 of landscape film: flexibility
The tensioned membrane structure is not rigid and will deform under wind load or snow load. Membrane structure adapts to external load through deformation. In this process, the curvature radius of the membrane surface in the direction of the load will be reduced until it can more effectively resist the load.
The flexibility of tension structure makes it possible to produce large displacement without lasting deformation. The elastic properties and prestress level of membrane materials determine the deformation and response of membrane structures. The flexible nature can stimulate people's architectural design inspiration.
Different membrane materials have different flexible procedures. Some films have good flexibility and will not be brittle or damaged due to folding. These materials are the basis and premise for the effective realization of movable and expandable structures.
Feature 4 of landscape film: sense of sculpture
The unique surface shape of tension membrane structure makes it have a strong sense of sculpture. The membrane surface achieves self balance through tension. The undulation of the negative Gauss film surface has a sense of balance, which makes the larger structure seem to float slightly between the heaven and the earth, as if it is free from the shackles of gravity. Whether indoor or outdoor, this sculptural texture is exciting.
