When building a house it’s fun like lego—–Q and A about prefabricated buildings

In the eyes of almost everyone, building a house is nothing more than the combination of sand, cement, steel, brick, etc., according to a certain proportion of a certain structure, so as to become a house. What if, someone said, building a house could be like building lego? The answer is yes, prefabricated buildings, the new building model, will make their lego dreams come true for more people.

In fact, prefabricated buildings began to attract interest in the early 20th century and finally came into being in the 1960s. Britain, France, the Soviet union and other countries first tried. Because prefabricated buildings were built quickly and cost less to produce, they quickly spread around the world. The earliest prefabricated building was a wooden frame house used by the immigrants to America in the 17th century.In China, prefab architecture first appeared in Beijing in the 1980s, but for a long time after that, it was virtually “dead” in China. It was only in recent years that the prefab model returned to the public eyes. What is a prefabricated building? A building made of prefabricated parts assembled on a construction site. Take a simple example, like lego bricks that children play with. Lego manufacturers design and make the bricks into a variety of shapes, and children make their own creations by piecing them together according to their own ideas.

More important than the flexibility of design is the practical advantage of construction. Like, environmental protection, high efficiency, standard, green and so on. But understanding the practical advantages of prefab buildings is more in the realm of expertise, and for most people prefab is probably just a technical term. More people are concerned about what kind of difference this architectural model can bring to their living.

Q1: can prefabricated houses keep warm in winter?

A1: When prefabricated buildings are constructed, thermal insulation materials will be integrated into the prefabricated parts according to the construction requirements. And some beams and columns will be done in advance in the prefab.

Q2: how to ensure the quality of construction and assembly because of the prefabricated building model?

A2: The biggest feature of prefabricated buildings is the high technology content. In the design stage, diversified and all-round physical experiments are carried out. In the production stage, the quality control ability of the factory is greater than that of the traditional cast-in-situ construction method.

Q3: when assembling prefabricated parts, how to avoid seepage, frost heave (integration decoration), corrosion and other problems?

A3:At present, most prefabricated buildings solve the problem of water leakage through structural, structural and material waterproofing. Reduce the manufacturing error of door and window openings of prefabricated door and window parts, ensure the accurate installation of thermal insulation outer window made by the factory, and improve the thermal insulation effect.

Q4: when prefab house is being decorated, what is the difference with traditional house?

A4:  The decoration of prefab house is “complete decoration”. In the process of production and construction, has been the late decoration of artificial water, electricity, heating, housing load-bearing walls for the second modification of the problem in advance. The waste of manpower, material and financial resources was avoided. When owner decorates his house, can put more emphasis on the interior decoration design of the house.

Since 2016, China has decided to promote prefab buildings nationwide and made a breakthrough. Local prefab building production bases have also been built across the country. It is believed that in the future, more and more buildings will join the ranks of prefabricated buildings.
