【 Abstract 】 A building assembled by prefabricated parts on the site is called a prefabricated building. According to the form and construction method of prefabricated components, it can be divided into five types, such as block building, plate building, box building, skeleton plate building and lift slab building.

With the development of modern industrial technology, the construction of houses can be manufactured in batches and sets, just like the production of machines. As long as the prefabricated housing components, shipped to the site assembly.

Prefabricated buildings began to attract interest in the early 20th century and finally came to fruition in the 1960s. Britain, France, the Soviet Union and other countries made the first attempt. Because of the speed of construction of prefabricated buildings, and the low cost of production, it has been rapidly promoted around the world.

The shape of the early prefabricated buildings was stiff and monotonous. Later, design improvements were made to increase flexibility and variety, allowing prefabricated buildings to be built not only in batches, but also in a variety of styles. In the United States, there is a kind of mobile home, which is a relatively advanced prefabricated building, and each residential unit is like a large trailer, which can be used as long as it is pulled to the site by a special car, and then hoisted to the floor pad by a crane and connected to the embedded water channel, power supply, and telephone system. The mobile home has heating, bathroom, kitchen, dining room, bedroom and other facilities. The mobile home can be a single unit, but also can be connected to each other.
