Prefabricated buildings began to attract people's interest in the early 20th century, and finally realized in the 1960s. Britain, France, the Soviet Union and other countries made the first attempt. Because of the fast construction speed and low production cost of prefabricated buildings, they are quickly popularized all over the world. The appearance of the early prefabricated buildings was relatively rigid and the same. Later, people made improvements in design, increasing flexibility and diversity, so that prefabricated buildings can not only be built in batches, but also have rich styles.

Types of prefabricated buildings

1. Block building

A large number of building components, such as exterior wall panels, interior wall panels, laminated panels, balconies, air-conditioning panels, stairs, prefabricated beams, prefabricated columns, etc. are all produced and processed in the workshop. Conducive to quality control.

2. Plate construction

It is assembled from prefabricated large-scale interior and exterior wall panels, floor panels and roof panels, also known as large-slab buildings. It can effectively reduce the weight of the structure, improve labor productivity, expand the usable area of ​​the building and the anti-vibration function, and is the main type of prefabricated building.

The wall panels are divided into load-bearing wall panels and decorative wall panels. The load-bearing wall panels are mostly reinforced concrete panels, and decorative wall panels such as external wall panels are mostly reinforced concrete composite panels with thermal insulation layers, as well as special steel-wood thermal insulation composite panels. and other wall panels with exterior finishes. All kinds of plates can be load-bearing after hoisting and assembling, the construction speed is fast, and the construction price is low!

3. Box building

It is a prefabricated building developed on the basis of sheet metal construction. The biggest feature is that all room units or small studio kitchens, bathrooms or stairwells are made into load-bearing boxes in structure, and then integrated with wall panels and floor slabs. This kind of building has a higher degree of industrialization and faster on-site installation. Not only can the structural part of the box be completed in the factory, but also the interior decoration and equipment can be done well, and even furniture, carpets, etc. can be completed. On-site hoisting, Connect the line and you are ready to use!

4. Skeleton plate construction

It consists of prefabricated skeletons and panels. Its load-bearing structure generally has two forms, one is a frame structure system composed of columns and beams to form a load-bearing frame, and then shelving the floor and non-load-bearing internal and external wall panels; the other is a column and floor. The interior and exterior wall panels are non-load-bearing members. The load-bearing frame can be a heavy reinforced concrete structure or a heavy steel structure, with light weight and flexible internal separation, suitable for multi-storey and high-rise buildings.

5. Rising slabs and elevated buildings

The structural system of this kind of building is combined load-bearing by slabs and columns. It is to repeatedly pour each floor slab and roof slab on the bottom concrete ground, erect prefabricated reinforced concrete columns, and use the columns as guide rods to raise the floor slabs and roof slabs to the design height. , and then fix it. As for the internal and external walls, reinforced concrete can be cast in place, brick walls can also be built, and other lightweight curtain walls can also be installed. It moves a large number of cast-in-place processes to the ground, reducing high-altitude operations and vertical transportation, saving formwork and scaffolding works, and reducing the construction site area. Multi-storey garage, etc.

Features of prefabricated buildings

1. A large number of building components, such as exterior wall panels, interior wall panels, laminated panels, balconies, air-conditioning panels, stairs, prefabricated beams, prefabricated columns, etc. are all produced and processed by the workshop. The centralized production greatly reduces the engineering cost, and at the same time It is also more conducive to quality control.

2. The building parts produced by the factory are transported to the site for assembly, which reduces the formwork engineering and manual workload, and speeds up the construction speed, which is of great significance for reducing the project cost.

3. Prefabricated construction turns the entire building from a project into a product. The more standard the components, the higher the production efficiency and the lower the cost. With the digital management of the factory, the cost performance of the entire prefabricated building is far from comparable to the traditional construction method.

4. Unlike traditional buildings, the main body must be completed before the decoration can be carried out. The prefabricated building can complete the decoration and decoration of each prefabricated part and then assemble it, which realizes the synchronization between the decoration and the main project and reduces the construction process. , reducing the project cost.

5. The choice of building materials for prefabricated buildings is more flexible, and the use of various energy-saving and environmentally friendly materials such as light steel and wood panels makes prefabricated buildings more in line with the concept of green buildings.
