The station roof model is constructed from stretched canvas
Tensile Membrane Structure is a new type of material structure discovered and developed by the famous German architect Frei Otto. This type of structure applies tension to the frame system and canvas (covering membrane) above, has a lightweight structure and impressive span-crossing ability.
Awnings made from stretch canvas have been used and developed for many years in developed countries around the world. However, in recent years, stretch canvas has become widely known and used thanks to its outstanding properties. Especially applied to projects with large areas such as stations, airports, pedestrian streets...
Three common materials can be applied to station roof models
The diversity of materials as well as colors and designs of canvas can meet diverse usage needs, allowing architects to unleash their creativity in iconic spaces. 3 common materials in the design and construction of station roofs are:
- PVDF is a 3-layer canvas with good resistance to weather conditions, durability and flexibility. The fabric is created by weaving the yarn into the fabric base and treating and repairing the resin on both sides of the base. The central fabric base is divided into polyester fiber and glass fiber. In recent years, through continuous improvement of materials, weather resistance and anti-rust properties have been improved. Self-cleaning PVDF membrane can last for more than 15 years.
- PTFE The main feature to note when using PTFE is that it must be handled very carefully during the construction phase. Installing PTFE-coated fiberglass fabric requires more intricate details than PVDF fabrics. PTFE (glass) cloth would be the preferred choice to be used if cleaning is difficult or impractical in some projects. Because FTFE's inherently 'non-stick' surface resists adhesion and rainwater can help clean off most dirt. PTFE's lifespan can be up to 25 years
- ETFE Has a stretching feature to create curves for the canopy. In addition, this is a transparent tarpaulin that protects from rain and sun but allows light to pass through. The amount of light that penetrates depends on the pattern on the canvas that the customer chooses. The light transmittance is 95%, allowing the plants below to grow naturally. And not affected by ultraviolet rays, air pollution and other forms of environmental weathering. This is the top choice for a simple and economical light canopy.
Based on usage needs, personal preferences as well as investment costs, investors can consider choosing the most suitable roof model for their project to bring value and aesthetic effect. most optimal.
Installation of station roof model
The design and construction of station roofs made from stretched canvas is a combination of the straight, long, strong lines of the steel structure and the soft curves of the canvas. The creativity of architects and the meticulous calculations of structural engineers will produce station roof models with the most wonderful applications.
There are two main forms when constructing stretch canvas roofs:
- Connect to existing construction
- Connect to a column system designed and built to suit the space
With a lighter weight than traditional roofing fabrics and a simple, quick installation process, it helps the operations of railway stations, airports, etc. to be less interrupted.
