First: There are a lot of prefabricated components. The following points are summarized: cost, duration, quality, safety, and environmental protection. In general, prefabricated components are all manufactured by the factory. Quality, safety and environmental protection are easier to control than on-site cast-in-place, and for the United States, workers working outdoors are three times more expensive than those working in factories. China is not that much, but it must also Nearly twice. If a large number of prefabricated components are used, a large number of field workers can be reduced.
Second: the problem of the construction period. For example, last year, a domestic construction company built a 10-story building in three days, and all prefabricated steel components were directly put up. Then I snorted on the Internet and said who would dare to buy this building. In fact, I feel that this is completely okay, but the preconditions mainly include the following: reasonable deep drawing design, rigorous construction organization design, perfect technical disclosure and obedient workers. These things are the hardest and most time-consuming. In addition, China is now also promoting the use of prefabricated components. It is said that most of the engineering bureaus of China Construction have already established or are building prefabricated component bases, one in Tianjin Wuqing and the third in Wuhan. I think prefabricated component technology is also the way out for China's construction industry, but there is still a long way to go.
