What Are the Prefabricated Components of Houses

Prefabricated components of houses can be classified by material into concrete prefabricated components, steel structural components, aerated concrete components, and rock wool board components; by function into horizontal components, vertical components, and special-shaped components, in addition to some specific types of components.

Classification by material:

• Concrete prefabricated components: Such as solid shear walls, composite floor slabs, etc. These components have high strength and a long service life. They are widely used in construction, can withstand large loads, and ensure the stability of building structures.
• Steel structural components: Suitable for high-rise and large-span buildings. Steel has high strength and good toughness, enabling steel structural components to meet the requirements of high-rise buildings for structural strength and large-span buildings for spatial span.
• Aerated concrete components: Have strong heat insulation and earthquake resistance capabilities. Aerated concrete has many tiny pores inside, which can effectively prevent heat transfer and improve the component's earthquake resistance performance.
• Rock wool board components: Provide heat insulation, sound insulation, and fire protection. Rock wool is an inorganic fiber material with good heat insulation, sound insulation, and fire protection properties. It is commonly used in building walls, roofs, and other parts.

Classification by function:

• Horizontal components: Such as hollow floor slabs, double-T slabs, prefabricated composite floor slabs, steel bar truss floor decking, etc. These components mainly bear horizontal loads, such as live loads on floors, and provide horizontal support for buildings.
• Vertical components: Such as load-bearing walls, columns (including solid, hollow, and those with thermal insulation layers), prefabricated concrete columns, etc. They mainly bear vertical loads, transfer the loads from the upper parts of the building to the foundation, and ensure the vertical stability of the building.
• Special-shaped components: Such as integrated bathrooms, bay windows, prefabricated balconies, etc. These components have special shapes and can meet the diverse design requirements of buildings, improving the building's usability and aesthetics.

In addition, common ones also include prefabricated composite beams, prefabricated concrete exterior wall panels, prefabricated concrete interior wall panels, and components related to prefabricated underground garages. They play important roles in specific construction scenarios, improving the efficiency and quality of construction.
