The curtain wall panels are made of fiberglass reinforced concrete?
Since the start of construction, Jinan Rail Transit Line 8 has been committed to creating a green construction model, building the country's first full-range permanent and prefabricated superimposed station, taking the lead in using clustered reverse circulation pneumatic down-the-hole hammers to reduce construction noise in Jinan Rail Transit construction, and completing the application and implementation of technologies such as concrete self-waterproofing... Now, Line 8 has used the "black technology" that combines beauty and strength in the construction of elevated stations - GRC curtain wall panels.
What is GRC? Simply put, GRC is the abbreviation of fiberglass reinforced concrete. It is not ordinary concrete, but it is added with alkali-resistant glass fiber, with high strength, good toughness, and can be made into various shapes. It is simply the "variable star" in the construction industry! The GRC curtain wall panels used in the elevated stations of Line 8 are composite materials composed of cement, quartz sand, fiberglass, etc., with "lightweight technology + green genes".
How powerful is the GRC of Line 8? Green and environmentally friendly, energy-saving and low-carbon. The curtain wall of the elevated station on Line 8 is assembled from GRC curtain wall panels on both sides of the inside and outside, and each curtain wall panel is only 25 mm thick. Compared with the traditional concrete curtain wall with a thickness of more than 150 mm, its self-weight is reduced by more than 84%. In terms of environmental performance, GRC technology shows the advantage of rolling resistance. The curtain wall of a single station on Line 8 is assembled from 796 GRC curtain wall panels of different shapes, which can reduce the amount of concrete by about 700 cubic meters and reduce carbon emissions by about 700 tons. The GRC curtain wall has high strength, good durability, and can withstand bad weather. Ingenuity is also added to the design, which not only reduces the disturbance caused by wind resistance, but also reduces the time for rain and snow to fall on the surface to erode the concrete, thereby improving safety.
Safe and durable, with high construction efficiency. GRC curtain wall panels are produced in an industrialized prefabricated mode. They are transported to the site and assembled like building blocks. The construction precision is high and the quality is well controlled. At the same time, it avoids the safety hazards and wood waste caused by the erection of scaffolding and supporting formwork in the traditional concrete pouring form, and the labor can be reduced by about 40%, and the construction speed is increased by about 50%.
Good-looking and futuristic. GRC technology not only brings environmental benefits, but also opens the "appearance revolution" of rail transit buildings. Compared with traditional concrete pouring construction, GRC curtain wall panels have strong plasticity and can change different shapes according to the design to create various smooth lines and unique shapes. The curtain wall of a station of the elevated station of Line 8 contains 52 different shapes of GRC curtain wall panels. The deep window cover part of the component is a hand-made imitation of the Longshan cultural relic texture board, which reflects the historical and cultural characteristics of Jinan and gives the building art and humanistic attributes; the inner side is designed with a light strip. When it is turned on at night, the entire station is like a glowing work of art, with a futuristic sense. With the blessing of technological aesthetics, the Line 8 elevated station bids farewell to "sameness" and becomes a new landmark of the city!
