What is the Structure of a Prefabricated House
A prefabricated house is a form of construction where building components are industrially produced and assembled on-site, featuring a variety of structural types, including panel assembly, box assembly, frame assembly, as well as steel, concrete, and wooden forms.
From the perspective of assembly methods, there are three main types of prefabricated houses. Panel assembly involves prefabricating wall panels, floor panels, and other panel components required for the building in a factory, then transporting them to the construction site for assembly. This structural type offers fast construction speed, reduces on-site wet work, and improves building quality. For example, in the construction of some industrial plants, panel assembly structures can quickly erect the main framework of the plant, meeting the time requirements of industrial production.
Box assembly involves creating entire rooms or building units as 'box'-shaped components, which are internally decorated and equipped in the factory before being transported to the site for splicing. This structural form is suitable for buildings with relatively regular spatial requirements, such as apartments and hotels, significantly shortening the construction period and improving building standardization.
Frame assembly is based on a frame structure, where frame beams, columns, and other components are prefabricated in the factory, then assembled on-site, followed by the installation of floor panels, wall panels, and other enclosure structures. Frame assembly structures offer good seismic performance and spatial flexibility, commonly used in the construction of multi-story and high-rise buildings.
From the perspective of material forms, prefabricated houses mainly come in three types: steel, concrete, and wooden. Steel prefabricated houses offer high strength, light weight, fast construction speed, and good seismic performance, suitable for large-span and high-rise buildings. Concrete prefabricated houses provide good durability and fire resistance, with relatively low costs, widely applied in various types of buildings. Wooden prefabricated houses offer advantages such as environmental protection, energy efficiency, and comfort, commonly used in low-rise residential and vacation villa construction. Additionally, modular construction, as a form of prefabricated housing, breaks down the building into independent modules, which are manufactured in the factory and then assembled on-site, achieving a high degree of integration and standardization.
