Prefabricated House Finished Self-Built House
A prefabricated house finished self-built house is a construction method where house components are prefabricated in a factory and then transported to the homestead for assembly and fixation.
Construction Process
The construction processes of prefabricated houses vary across regions, yet they also share similarities. Taking rural prefabricated houses in South Korea as an example, the process begins with leveling the foundation and pouring a cushion layer. After excavating the foundation pit, a white plastic sheet is laid, and the foundation is poured without using steel bars. Once the concrete sets, anchor plates are installed, and a mobile crane is used to install foundation piles weighing about 5 tons. Beams are installed like building blocks, adjusted horizontally, fixed with nuts, and the gaps are filled with foam, while the nut fixation points are sealed with cement. Finally, the soil is backfilled, and the foundation is poured to complete the frame structure. In Henan, China, prefabricated components are manufactured in factories through precise calculations and mold forming. They are then transported to the homestead and assembled by workers, similar to building blocks. For example, it takes only 4 hours to hoist and assemble a house locally.
Cost and Price
The cost and price of prefabricated houses vary depending on factors such as region and house specifications. In Henan, China, the cost is approximately over 300 yuan per square meter, and building a large villa only requires a budget of tens of thousands of yuan. There are various prices for self-built cement prefabricated houses in rural areas on the market. In Xuzhou, Jiangsu, there is a wholesale price of 500.00 yuan per square meter. In Jining, Shandong, there are different prices such as 260.00 yuan per square meter and 500.00 yuan per square meter. In Hebei, prices range from 210.00 yuan per square meter to 4200.00 yuan per square meter.
Structure and Quality
The main body of prefabricated houses in Henan, China, is made of reinforced concrete structure, with a quality guarantee period of up to 70 years. This structure has high strength and stability, capable of withstanding certain external forces and providing a safe and reliable living environment for occupants.
Applicability
Prefabricated houses have a wide range of applications and can be used as residences, dormitories, office buildings, etc. They can be built up to 5 floors, meeting the usage needs in different scenarios. Whether for personal residence or commercial office purposes, this construction method can be chosen.
