Steel and bamboo timber used in building formwork is huge in China, and building formwork is an important tool for concrete structure construction. Experts pointed out that in cast-in-situ concrete structure engineering, formwork engineering generally accounts for 20%-30% of the cost of concrete structure engineering, 30%-40% of the workload of the project, and about 50% of the construction period. Formwork technology directly affects the quality, cost and benefit of Engineering construction, so it is an important content to promote the progress of construction technology in China.
With the development of the real estate industry and the construction of various projects in China, the template industry has developed rapidly. In 2009, the use of building formwork amounted to 585 million square meters, an increase of 7.3% year on year. Industry insiders expect that, in 2010, under the support of good policy of domestic investment and the environment of international economic environment gradually improving, the production scale of China's construction formwork industry will maintain a growth rate of about 10%; from 2011 to 2012, the average annual growth rate of production scale of China's construction formwork industry will be about 15%; by the end of 2012, the output of China's construction formwork industry will reach 220 million square meters left. Right.
According to statistics, China's steel formwork Market in 2009 was 153 million square meters, an annual growth rate of 6.9%. The output of steel formwork, including steel composite plate and all-steel large formwork, is 39.7 million square meters, with an annual growth rate of 6.6%. The new steel moulds are converted into about 3 million tons per year, which is equivalent to the steel consumption of 43 French Eiffel Towers (70,000 tons for Eiffel Towers), 27 Beijing Bird's Nest (110,000 tons for Beijing Bird's Nest) and 37 Hangzhou Bay Bridge (800,000 tons for Hangzhou Bay Bridge).
Now Plastic formwork, like PVC board formwork, PP hollow formwork are becoming more and more popolar in China.
