What is the English Translation of Prefabricated Concrete Houses

Prefabricated concrete houses, also known as prefabricated concrete assembled houses, refer to houses constructed from concrete components that are pre-made and assembled on-site.

Definition and Classification

Prefabricated concrete houses are built by industrially producing building components and assembling them at the construction site. Depending on the production location of the components, they can be classified into two types: on-site prefabrication and factory prefabrication. The former involves producing components at a temporary site near the construction site, while the latter involves manufacturing components in a specialized factory and then transporting them to the site. The core construction method involves using construction machinery such as cranes to combine and install factory-produced prefabricated concrete components (such as floor slabs, beams, walls, and columns). The construction process is divided into two stages: factory prefabrication of components and on-site installation, covering the complete sequence of design, manufacturing, transportation, installation, and decoration.

Technical Advantages

1. Shortened Construction Period: Components are produced simultaneously in the factory, and on-site installation is efficient, reducing the waiting time associated with traditional cast-in-place operations.
2. Cost Reduction: Industrial production reduces reliance on manual labor, minimizes material waste, and shortens the construction period, thereby lowering overall costs.
3. Environmental Protection and Energy Efficiency: On-site wet operations are reduced, resulting in approximately a 60% decrease in construction waste generation, along with significant reductions in noise and dust pollution.
4. Quality Control: Factory-standardized production ensures consistent component dimensions and strength, minimizing human errors.

Scope of Application and Core Components

This technology is suitable for building forms such as frame structures and shear wall structures, with core applications including:

• Prefabricated Floor Slabs: Such as composite floor slabs (composed of a prefabricated base slab and a cast-in-place layer);
• Prefabricated Beams: Such as prestressed composite beams (enhanced load-bearing capacity through prestressing technology);
• Prefabricated Walls: Such as sandwich insulation exterior walls (integrating insulation and structural layers);
• Prefabricated Columns: Used for vertical load-bearing structures.

Connection Technologies

Component connection methods are divided into two categories:

1. Wet Connections: Achieved through sleeve grouting connections or grout anchor connections, utilizing high-strength grout to fill metal sleeves or reserved holes, forming an integrated load-bearing structure.
2. Dry Connections: Employ embedded connectors (such as bolts and steel plates) or prestressing technology (transmitting force through tensioned steel strands), with prestressed connections significantly enhancing structural seismic performance, suitable for high-intensity earthquake zones.

Application Scenarios

Prefabricated concrete house technology is widely used in civil buildings such as residential homes, schools, and hospitals, as well as in infrastructure projects like industrial plants and bridges, particularly suitable for projects with high demands for construction efficiency and environmental protection.
