Prefabricated Concrete House Information
Prefabricated concrete houses are a form of construction that involves the industrial production of building components and their on-site assembly. They are characterized by high efficiency, high quality, environmental friendliness, low cost, and flexible design, and are widely used in rural self-built houses, commercial spaces, cultural and tourism projects, and affordable housing.
Development History
China's prefabricated concrete technology began in the 1950s and was initially applied to factory and residential construction. In the 1970s, driven by the policy of "three modernizations" in construction, technical systems such as large-panel structures and box structures were formed. In the mid-1980s, the technology stagnated due to cost and quality issues, but it experienced a resurgence in the 21st century due to its production efficiency and environmental advantages. Companies like Vanke Group developed prefabricated shear wall residential structural systems and applied prefabricated frame technology in engineering projects.
Structural Systems
These include fully prefabricated buildings (low-rise or multi-story buildings with lower seismic requirements), partially prefabricated buildings (where main components are prefabricated and connected on-site with cast-in-place concrete to form an integral structure), and other systems (such as prefabricated frame external cladding systems and prefabricated prestressed concrete frame structural systems).
Technical Characteristics
Connection Details: Steel bar connections are used, including grouted sleeve connections, lap connections, and welded connections, to ensure structural integrity. Supporting Components: Technologies such as the integrity of doors and windows, and the one-time completion of installation and decoration in wet rooms. Design Principles: Follow principles of reasonable force distribution, reliable connections, convenient construction, and fewer specifications with multiple combinations to achieve generalization, modularization, and standardization.
Core Advantages
High Efficiency: Fast construction speed, suitable for winter construction, and high production efficiency. High Quality: Good product quality and reduced material waste. Environmentally Friendly: Reduces resource consumption and construction waste emissions from the source, with full control over factory production. Low Cost: Overall cost reduction of 30%, with leasing models further lowering the threshold for use. Flexible Design: Standard module dimensions are 6m×3m×3m, allowing for free户型 design through splicing and stacking.
Application Scenarios
Widely used in rural self-built houses, commercial spaces, cultural and tourism projects, and affordable housing. For example, the affordable housing project in Shenzhen, Guangdong, was assembled from 6,028 concrete modules, significantly shortening the construction period and reducing disturbances to residents.
Market Situation
Prefabricated houses made in China are selling well overseas. In the first four months of 2026, the Guangzhou Customs District exported 1.4 billion yuan worth of mobile houses, a year-on-year increase of 38.1%. It is predicted that the global modular construction market will exceed 142.8 billion US dollars by 2030.
