Types of Prefabricated Houses
Prefabricated houses mainly come in three types: panel-assembled buildings, box-assembled buildings, and modular buildings. They can also be categorized into steel, concrete, and wooden forms based on their structure.
From the perspective of construction methods, panel-assembled buildings use prefabricated wall panels and floor slabs as their core components. These types of prefabricated houses are manufactured in factories with major components such as wall panels and floor slabs, which are then transported to the construction site for assembly. Their advantage lies in the ability to expand the usable area of the house, as the high manufacturing precision of wall panels and floor slabs reduces errors and space wastage that may occur during on-site construction. However, they also have certain limitations. Due to the high degree of standardization of components, they are somewhat restricted in terms of design flexibility and may find it difficult to meet some personalized and complex architectural design requirements.
Box-assembled buildings are composed of prefabricated functional units. They create independent 'box'-shaped prefabricated units for each functional area of the house, such as bedrooms, kitchens, and bathrooms, and then拼接 (assemble) them at the construction site. This construction method can significantly increase construction speed, improving it by 50% - 70% compared to traditional building methods, greatly shortening the construction cycle. However, due to the large volume of prefabricated units, they have high requirements for transportation and lifting equipment, necessitating corresponding large-scale transportation vehicles and lifting equipment to ensure the safe and accurate transportation and installation of the prefabricated units at the designated location.
Modular buildings divide the house into several independent modules, completing the integrated prefabrication and acceptance of building, structure, electromechanical, decoration, and other specialties within the factory. Each module contains part of the house's functions and only needs to be assembled upon arrival at the site for immediate use. This type of prefabricated house achieves a high degree of industrialized production, with high quality controllability, and requires less on-site construction work, having a smaller impact on the environment.
From the perspective of form, prefabricated houses mainly come in steel, concrete, and wooden forms. Steel prefabricated houses use steel as the main load-bearing structure, offering advantages such as high strength, light weight, and fast construction speed; concrete prefabricated houses adopt prefabricated concrete components, providing good durability and fire resistance; wooden prefabricated houses, on the other hand, use wood as the main material, featuring environmental protection, energy efficiency, and comfort, but with relatively weaker durability.
