Xinhe Cement Prefabricated House Structure

The Xinhe cement prefabricated house structure can be referred to as a prefabricated reinforced concrete house, fully named as the 'prefabricated reinforced concrete full-frame shear wall structure house'. Its core process combines factory prefabrication with on-site assembly.

Core Process and Module Composition

This structure uses high-precision molds in specialized production bases to cast core components such as walls, floors, beams, and columns in one go. Each module integrates multiple structures:

• Reinforcement Framework: Built-in Φ8-Φ12 steel reinforcement mesh combined with C30-C40 grade concrete forms a high-strength composite structure with a compressive strength of 25-30MPa, 1.5 times that of traditional brick-and-mortar structures.
• Insulation and Waterproof Layers: Walls are designed with slots for EPS insulation panels, which, when inserted on-site, improve thermal insulation by 40%, achieving warmth in winter and coolness in summer. Additionally, integrated waterproof layers reduce the risk of leakage.
• Pre-embedded Pipelines: Electrical and plumbing lines are pre-embedded within the modules, avoiding the need for on-site trenching that could damage the structure and enhancing construction efficiency and safety.

Connection Technology and Structural Performance

Modules are connected using two key methods:

• Prestressed Bolts: High-strength bolts ensure vertical and horizontal stability between modules.
• Welded Steel Plates: Steel plates are welded at critical joints to form an integrated frame, enhancing overall structural integrity.

In terms of performance, this structure can withstand wind speeds of up to 10 and has a seismic fortification intensity of 7 degrees (capable of resisting damage equivalent to the Wenchuan earthquake), making it suitable for earthquake-prone and windy regions.

Historical Background and Industry Status

Xinhe County once had the Xinxing Cement Prefabricated Component Factory (established in 1992 and deregistered in 2006), which primarily produced cement prefabricated panels. However, this factory has since exited the market. Currently, the technical standards and processes for the Xinhe cement prefabricated house structure have been upgraded to a more advanced prefabricated reinforced concrete system, integrating modular design, high-precision manufacturing, and the application of green building materials, aligning with modern trends in building industrialization.

Application Advantages

• High Construction Efficiency: Factory prefabrication reduces on-site work time, shortening the construction period by approximately 30%.
• Quality Control: Standardized production reduces human errors, ensuring more stable structural performance.
• Environmental Protection and Energy Efficiency: Reduces construction waste and dust pollution, while EPS insulation layers lower energy consumption.

This structure achieves efficient, safe, and sustainable building through industrialized production and modular assembly, representing an important development direction in modern architecture.
