Definition of Prefabricated Houses
Prefabricated houses refer to a form of construction where building components are industrially produced and then assembled on-site. This category encompasses various specific types, such as pre-cast houses, mobile houses, and modular buildings.
Pre-cast houses are a typical representative of prefabricated houses, emphasizing the industrial production of building components. In a factory setting, various parts of the building, such as walls, floors, beams, and columns, are manufactured according to precise designs and specifications. After completing quality inspections and preliminary processing in the factory, these components are transported to the construction site. On-site, construction workers assemble these components following design drawings, using reliable connection methods such as bolting and welding to piece together a complete building structure. This construction method significantly shortens on-site construction time, reduces the impact of weather and other factors on the construction schedule, and ensures easier quality control of components due to the high degree of standardization in factory production.
Mobile houses are also a common type of prefabricated house, dividing the house into several independent modules. In the factory, these modules undergo integrated prefabrication and acceptance across multiple disciplines, including architecture, structure, electromechanical systems, and interior decoration. This means that each module is already equipped with basic functionalities upon leaving the factory, such as laid-out electrical and water lines, and completed wall and floor finishes. After being transported to the site, these modules only require simple assembly to be quickly put into use. Mobile houses are characterized by high flexibility and strong mobility, often used in temporary buildings, construction site dormitories, emergency rescue scenarios, etc.
Modular buildings also fall within the scope of prefabricated houses, breaking down the entire building into individual independent modules. These modules are manufactured in the factory, including architectural structures, interior decoration, and equipment installation. Subsequently, these modules are transported to the construction site and assembled into a complete building through precise positioning and reliable connection techniques. Modular buildings enable a high degree of standardized and large-scale production, improving building quality and efficiency while also providing some flexibility for personalized architectural design.
