In China, the building energy consumption accounts for more than 27% of the total energy consumption, and it is increasing at the rate of 1% per year. According to statistics of the Ministry of construction, the building area of new buildings in urban and rural construction is nearly 2 billion square meters every year, of which more than 80% are high energy consumption buildings, and the proportion of building energy consumption in the total energy consumption of the country will rise rapidly from 27.6% to more than 33%. A large amount of wood will be consumed in the construction process, and the main consumption link comes from the use of formwork timbers in civil construction. In general construction, one cubic meter of timber is used for every 20 square meters. If Steel Railway Sleepers are used instead of ordinary timber, the use of timber can be reduced by 90%, that is to say, only 0.1 cubic meter of timber is consumed for every 20 square meters. It is estimated conservatively that 90 million cubic meters of timber can be saved per year according to the newly increased construction area of 2 billion square meters in China.
At present, the construction formwork in our country is mainly made of ordinary timber. Since the 1990s, China's building structure system has made great progress, with a large number of high-rise buildings, super high-rise buildings and large public buildings built. With the rapid development of large-scale infrastructure, new requirements are put forward for formwork construction technology. The promotion and application of Steel Railway Sleepers
have reformed formwork construction technology, saved a lot of wood, and achieved significant economic and social effects.
