What Are the Prefabricated Components of Houses?

Prefabricated components of houses mainly include various types classified by material, function, and specific categories.

From the perspective of materials, prefabricated components of houses can be divided into concrete prefabricated components, which are the most common type. Made primarily of concrete and prefabricated using molds, they feature high strength and good durability, widely used in building structures; steel structural components, with steel as the main material, they offer advantages such as light weight, high strength, and fast construction speed, often used in high-rise buildings and large-span spatial structures; aerated concrete components, made from aerated concrete, they are lightweight and have good thermal insulation properties, suitable for non-load-bearing walls and other parts; rock wool board components, with rock wool board as the core material, they have good fire resistance and thermal insulation properties, commonly used in building exterior wall insulation systems.

Based on function, prefabricated components of houses can be classified as horizontal components, such as hollow floor slabs and double-T slabs, primarily used to bear horizontal loads, such as load transfer in floor and roof areas; vertical components, including load-bearing walls and columns, available in solid, hollow, and insulated types, they mainly bear vertical loads, such as the self-weight of buildings and live loads, serving as the main support parts of building structures; special-shaped components, such as integrated bathrooms and bay windows, these components have complex shapes and are usually customized according to the special needs of architectural design to meet functional and aesthetic requirements of buildings.

In terms of specific categories, prefabricated components of houses mainly include beams, such as prefabricated concrete T-beams and rectangular beams, which are the main components in building structures that bear bending moments and shear forces; slabs, such as prefabricated concrete flat slabs and hollow slabs, used to form horizontal structures like floors and roofs; columns, such as prefabricated concrete square columns and circular columns, which are vertical support components in building structures; architectural decoration fittings, such as prefabricated wall panels, prefabricated stairs, and prefabricated balconies, these components not only have structural functions but also serve decorative purposes, improving construction efficiency and ensuring building quality.
