ETFE membrane structures are widely used in transparent roofs, curtain walls and long-span buildings.
Specific applications include the following aspects:
1. Transparent roof: ETFE film can be used to cover the top of the building to achieve indoor lighting, shading and insulation functions.
2. Curtain wall: ETFE film can be used to cover the exterior wall of the building to increase the aesthetics and light transmission of the building.
3. Long-span building: ETFE membrane can be used for long-span structures of buildings, such as stadiums, exhibition halls, etc., to achieve the coverage and lighting of large Spaces.
4. Greenhouse: ETFE film can be used in greenhouse structure to provide good lighting conditions and climate control.
Architectural advantages of ETFE membrane structure:
1. Lightweight: The proportion of ETFE film is only 1% of glass, which is lighter than glass or metal materials, which can reduce the building's own weight and load and reduce construction costs.
2. Light transmittance: ETFE film has excellent light transmittance, which can make the indoor get better natural lighting effect, reduce energy consumption and lighting costs.
3. Weather resistance: ETFE film has good weather resistance and corrosion resistance, applied to outdoor weather tests, such as light, heat and cold, wind and rain, bacteria and other comprehensive damage.
4. Flexible design :ETFE film can be freely designed according to the shape and needs of the building, and can achieve various shapes such as curved surface and spherical surface.
5. Sustainability :ETFE membrane is a recyclable material that meets the requirements of sustainable development and has less impact on the environment.
ETFE membrane structure construction method:
1. Film pre-stretching: Before installing ETFE film, it is necessary to pre-stretch the film. This step can increase the weatherability and corrosion resistance of the film, while reducing the deformation of the film during use and fixing the film by bolting or welding.
2 Film material fixation: ETFE film usually uses aluminum alloy or steel as a support structure on the support structure.
At the same time, the edge part of the film material needs to be sealed to ensure that the connection between the film material and the support structure is tight and reliable.
3. Air bag inflation: After the installation is completed, the air bag inside the film needs to be filled with gas through the inflation system to maintain the shape and stability of the film.
The inflation system usually consists of a compressed air unit, an air bag and a control system.
