Juancheng Cement Prefabricated House

There is currently no directly targeted information on Juancheng cement prefabricated houses, but cement prefabricated houses (prefabricated reinforced concrete houses) have the following characteristics and technical principles:

I. Structure and Construction Process Cement prefabricated houses adopt the "factory prefabrication + on-site assembly" model. Core components such as walls, floors, beams, and columns are cast in one go in the factory using high-precision molds. Each module integrates a steel reinforcement framework, insulation layer, waterproof layer, and pipeline pre-embedding system, forming standardized "building blocks" that are connected into an overall framework on-site through prestressed bolts and welded steel plates. This process significantly shortens the construction period. For example, the main assembly of a 200-square-meter house takes only 4 hours.

II. Material and Performance Advantages

1. Strength and Durability: Using C30-C40 grade concrete with built-in Φ8-Φ12 steel reinforcement mesh, the compressive strength reaches 25-30 MPa, which is 1.5 times that of traditional brick-and-mortar structures, with a warranty period of up to 70 years.
2. Thermal Insulation Performance: The walls have reserved slots for EPS insulation layers. After on-site embedding, the thermal insulation performance is improved by 40%, achieving a warm winter and cool summer effect.
3. Disaster Resistance: The modules are connected to form an overall framework, with a wind resistance rating of up to Level 10 and a seismic fortification intensity of 7 degrees (capable of withstanding the damage level of the Wenchuan earthquake). However, they are only suitable for non-seismic zones or low-rise buildings. Experts emphasize that for buildings with too many floors, it may be difficult to meet seismic design requirements.

III. Economic Efficiency and Applicability

1. Cost Control: Taking a 200-square-meter house as an example, at a cost of 300 yuan per square meter, the total construction cost is about 60,000 yuan, and the module dimensions can be customized according to needs.
2. Construction Limitations: The key technology lies in the quality of assembly connections. If the splicing is properly handled and the design is reasonable, it can meet basic building functional requirements. However, the number of floors must be strictly controlled, and high-rise buildings may not be suitable due to structural stability issues.

IV. Application Recommendations Cement prefabricated houses are suitable for low-rise building scenarios in non-seismic zones that have high requirements for construction speed and durability, such as rural self-built houses and temporary resettlement houses. When choosing, it is necessary to focus on examining the manufacturer's assembly process and connection node design to ensure compliance with local seismic codes.
