Prefabricated Construction
Definition
With the development of modern industrial technology, building houses can be manufactured in batches and sets like machine production. Just transport the prefabricated house components to the construction site and assemble them.
Prefabricated buildings began to arouse people's interest in the early 20th century and were finally realized in the 1960s. Britain, France, the Soviet Union and other countries were the first to make attempts. Due to the fast construction speed and low production cost of prefabricated buildings, they have been rapidly spread around the world.The appearance of early prefabricated buildings was relatively dull and uniform. Later, people made improvements in the design, increasing flexibility and diversity, so that prefabricated buildings can not only be built in batches, but also have rich styles. There is a kind of mobile home in the United States, which is a relatively advanced prefabricated building.
Features
1. A large number of building components are produced and processed in the workshop. The main types of components include: exterior wall panels, interior wall panels, laminated panels, balconies, air conditioning panels, stairs, prefabricated beams, prefabricated columns, etc.
2. A large number of on-site assembly operations are greatly reduced compared with the original cast-in-place operations.
3. Adopt integrated design and decoration. The ideal state is that decoration can be carried out simultaneously with the main construction.
4. With the standardization of design and the informational of management, the more standard the components, the higher the production efficiency, and the corresponding component costs will decrease. With the digital management of the factory, the entire prefabricated building will become more and more cost-effective.
5. Meet the requirements of green building.
Types
block building
Prefabricated buildings that use prefabricated block materials to build walls are suitable for building 3 to 5-story buildings. If the strength of the blocks is increased or steel bars are configured, the number of layers can be increased appropriately. Block construction has strong adaptability, simple production technology, easy construction, low cost, and can also use local materials and industrial waste.
Panel construction
It is assembled from prefabricated large-scale internal and external wall panels, floor slabs, roof panels and other panels, and is also called large-panel construction. It is the main type of fully prefabricated buildings in industrialized system buildings. Panel construction can reduce structural weight, improve labor productivity, expand the building's usable area and earthquake resistance. The interior wall panels of panel buildings are mostly solid or hollow reinforced concrete panels; the exterior wall panels are mostly reinforced concrete composite panels with an insulation layer. They can also be made of lightweight aggregate concrete, foam concrete or macroporous concrete with Exterior cladding.
