Prefabricated Wall Structure of Houses

The prefabricated wall structure of houses is a core building system that involves the industrial production of building components and their on-site assembly, featuring modularity, high performance, and efficient construction.

1. Types and Construction of Prefabricated Walls

Prefabricated walls are key components of prefabricated buildings, primarily classified into panel-type, box-type, and frame-type assemblies. Their construction involves one-time casting using high-precision molds, integrating steel reinforcement skeletons, insulation layers, waterproofing layers, and pre-installed piping systems. Modules are connected using pre-stressed bolts and welded steel plates to form an overall frame structure. For example, prefabricated walls in prefabricated reinforced concrete houses can achieve an integrated design of 'structure-insulation-piping,' reducing secondary on-site construction processes.

2. Material and Performance Advantages

Prefabricated walls typically use C30-C40 grade concrete with embedded Φ8-Φ12 steel mesh, achieving a compressive strength of 25-30MPa, which is 1.5 times that of traditional brick-and-mortar structures. The walls are designed with slots for EPS insulation layers, which, when inserted on-site, improve thermal insulation performance by 40%, effectively reducing energy consumption. Additionally, the industrial production mode of prefabricated walls ensures the stability of material quality, avoiding quality fluctuations caused by human factors during on-site construction.

3. Connection Construction and Structural Safety

Connection technology is the core of prefabricated wall structures, including connections for concrete composite beams and prefabricated stairs. Modules are rigidly connected using pre-stressed bolts and welded steel plates, achieving a wind resistance rating of Level 10 and a seismic fortification intensity of 7 degrees (equivalent to the destructive force of the Wenchuan earthquake). This connection method not only ensures the integrity of the structure but also reduces construction errors through standardized design, enhancing building safety.

4. Application Scenarios and Comprehensive Benefits

Prefabricated wall structures are widely used in rural self-built houses, commercial spaces, and cultural tourism projects. Their advantages include:

• Reduced Construction Time: A 100㎡ house can be fully assembled in just 2 days, an 80% reduction compared to traditional construction methods;
• Cost Savings: Overall costs are reduced by 30%, primarily due to decreased labor costs and controlled material waste;
• Environmental Benefits: Construction waste is reduced by 90%, meeting green building standards;
• Flexibility: As a special form, prefabricated fences support decorative styles such as antique and European designs and can be reused.

5. Special Forms of Prefabricated Fences

Prefabricated fences are produced using materials such as cement, magnesium chloride, and perlite through factory prefabrication and are assembled on-site using embedded parts, columns, and bottom beams. They achieve a compressive strength of 21.3-31.0MPa and are suitable for temporary buildings or landscape enclosures. This form features a short construction period (usually completed within 1 day) and can be disassembled and reassembled, further expanding the application scenarios of prefabricated walls.
