Characteristics of prefabricated houses and their present situation in China

At first, Bian Xiao wanted everyone to know such a problem. How many of you know and understand the prefabricated houses? To tell the truth, Bian Xiao was also confused about this term before doing his homework. Then let's take a look at the characteristics of prefabricated houses and the present situation in China!

Characteristics of prefabricated houses

1. According to the fact that there is no mass production at present, the progress of prefabricated houses is about 30% faster than that of traditional construction methods.

2. There is no problem with the safety of the assembly room, because the prefabricated stairs and external walls need to be overlapped with reinforced concrete when they are transported to the construction site, not simply connected. Each floor is penetrated by steel bars, and the building structure is solid.

3. Compared with traditional houses, prefabricated houses have higher component accuracy, which can greatly improve the common quality problems such as wall cracking and leakage, and improve the overall safety level, fire resistance and durability of houses. Using light partition wall system, the owner can change and decorate as needed.

4. During the use of the house, the assembled house is more energy-saving and environmentally friendly. For example, the new insulation layer has better insulation effect. If household metering is implemented, the room temperature of the assembled house will be higher at the same temperature, so the householder can consider lowering the heating temperature, saving heating costs and reducing energy consumption.

5. Assembled houses are of great benefit to energy conservation and environmental protection. Through factory production and on-site assembly construction, construction waste and sewage can be greatly reduced, construction noise can be reduced, harmful gas and dust emissions can be reduced, and on-site construction and management personnel can be reduced. Generally, it can save 20% materials and 60% water.

6. The housing industrialization of collective housing is not only conducive to the capital flow of development enterprises, but also can improve the speed of housing listing, so it can greatly slow down the current situation of insufficient market supply and adjust the supply relationship. After large-scale promotion, it can reduce the construction cost and also play a role in curbing housing prices.

7. Comprehensive cost accounting shows that the construction cost of prefabricated houses is higher than that of traditional construction methods, about 400 yuan per square meter. After large-scale promotion, the construction cost can be reduced.

Present situation of prefabricated houses in China

After entering the 1990s, due to the design level, the fineness of construction, the backwardness of assembly technology and the rapid development of cast-in-place concrete technology, the application of prefabricated buildings in civil buildings was at a low point.

In recent ten years, with the rapid development of China's economy and technology, rising labor costs, improving the processing accuracy and quality of prefabricated components, and improving the construction technology and management level of prefabricated components, the application of prefabricated components is heating up again and showing a rapid development trend.

At present, some domestic construction enterprises, such as Shanghai Vanke Group, Nantong Construction General Contracting Co., Ltd. and Shanghai Ruian Group, have adopted prefabricated buildings in their projects and achieved good practical value and demonstration effect.

I believe that after reading the homework done by the above small series, everyone is familiar with the characteristics of prefabricated houses and the current situation in China. Generally speaking, prefabricated housing is conducive to promoting the process of urbanization and is of great benefit to the development of our country.
