The SuiZhou High Speed train station ETFE membrane Structure has an area of 16000 m2 and took 90 days to complete.
The Millennium Ginkgo Valley in Suizhou is one of the four densely integrated ancient ginkgo settlements in the world. During the Mid-Autumn Festival, the leaves under the ginkgo tree flew like a golden paradise. SuiZhou High Speed train station ETFE membrane Structure is the inspiration drawn from this, and the natural artistic conception "under the ginkgo tree" is integrated into the building.
In order to abstractly express the morphology of ginkgo leaves, SuiZhou High Speed train station ETFE membrane Structure uses "umbrella-like unit bodies" as the main structure. Multiple "umbrella-like units" form a tall tree-like structure, which is connected into a dynamic roof. The high and low buildings are like old trees in the ancient village, reflecting the beauty of the architectural structure. Taking into account the three basic functional elements of light transmittance, diffuse reflection, and gold, the "umbrella unit body" was finally built with an ETFE film structure.
The interior of the station is filtered by the transparent membrane structure to produce soft diffused light, avoiding glare and direct sunlight, and the indoor illumination is more uniform. The area of the membrane structure skylight is also determined by the previous lighting simulation calculation, so that the waiting hall can meet the lighting requirements during the day even if it is cloudy.
Although the performance of the ETFE film looks very weak, the tensile strength of the ETFE film at room temperature can reach 55 N/mm². The conventional physical properties are equivalent to the iron sheet of the same specification. Under the premise, it is difficult to tear and damage by manpower; in addition, the transmittance of ETFE film can reach up to 95%, the density is 1.75g/cm³, the working temperature is -190℃~+150℃, the B1 class fireproof, has a high degree of non-stick self Cleanliness, can be used outdoors for more than 20 years. Combining these characteristics, ETFE becomes a light, thin, but very tough building material, known as "soft glass."
In the daytime, light penetrates the ETFE membrane structure to slowly reveal the internal structure, just like the texture of leaves, making the architectural space vivid and full of vitality. At night, the station is lit by LED lights installed in the membrane structure cavity to form a luminous body, like a bright "lantern", illuminating the way for passengers to go home.
The completion of the SuiZhou High Speed train station ETFE membrane Structure gives Suizhou a new vigor, brings a new period of development opportunities for Suizhou, and shows the unique local style of Suizhou.
