Types of prefabricated buildings

Prefabricated buildings began to attract interest in the early 20th century and were finally realized 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 early prefabricated buildings were rigid in appearance. Later improvements were made to the design, adding flexibility and variety, so that prefabricated buildings could not only be built in batches, but also in a variety of styles.

1. Block building

A large number of building components, such as exterior wall panels, interior wall panels, laminated panels, balconies, air conditioning panels, staircases, prefabricated beams, prefabricated columns, etc. are all produced and processed by the workshop.

2. Panel building

It is assembled from prefabricated large inner and outer panels, floor panels and roof panels, and is also known as the big board building. It can effectively reduce the structural weight, improve labor productivity, expand the use of the building area and seismic function, is the main type of prefab building.

Wallboard is divided into load-bearing type wallboard and decorative wallboard, load-bearing wallboard is mostly reinforced concrete board, decorative wallboard such as exterior wallboard is mostly reinforced concrete composite board with insulation layer, and special steel and wood insulation composite board with exterior veneer wallboard. All kinds of plate hoisting group can bear the load, the construction speed is fast, the construction price is low!

3. Box architecture

It is a kind of prefabricated building developed from the plank building. The biggest characteristic is to make all room unit or cubicle kitchen, toilet or stair well into load-bearing box in construction, wait with wall board and floor board to form integral whole again. This kind of building factory is changed the degree is higher, the spot installs faster, not only can complete the structural part of the box in the factory, and the interior decoration and the equipment also can do well, even furniture, carpet and so on also can complete completely, the spot hoisting, connect good pipeline can use!

4. Skeleton plate construction

It consists of prefabricated bones and plates. Its load-bearing structure generally has two forms, one is composed of columns, beams load-bearing frame, and then use the floor and non-load-bearing internal and external wallboard frame structure system; The other is a load-bearing plate and column structure system composed of columns and floor slabs. The load-bearing frame can be a heavy reinforced concrete structure or heavy steel structure, with light weight and flexible internal separation, suitable for multi-storey and high-rise buildings.
