Chongqing Cement Prefabricated Integrated Housing

Chongqing cement prefabricated integrated housing (prefabricated cement houses) is a new type of building form centered around on-site assembly of factory-prefabricated components, with practical application cases in places like Tongliang Tuqiao Town.

I. Size and Customized Design

The size of prefabricated cement houses can be flexibly adjusted according to needs. Taking Tongliang Tuqiao Town as an example, the house size ordered by local villagers is 3.2 meters × 3.8 meters, with an area of approximately 12.16 square meters. Moreover, the manufacturer provides 8 sets of molds, which basically cover common housing construction needs. If users have special size requirements, personalized design can be achieved through mold customization to meet the living or functional needs of different scenarios.

II. Outstanding Structural Safety Performance

This type of housing adopts a full-frame shear wall design, with strong structural stability. The specific manifestations are as follows:

• Earthquake resistance: The designed seismic fortification intensity is 7 degrees, and it can withstand an earthquake of magnitude 8. It disperses seismic energy through the synergistic effect of the frame and shear walls.
• Wind resistance: In a 12-level typhoon environment, the modules are connected by prestressed bolts to ensure no risk of loosening or detachment.
• Fire resistance: The fire resistance limit of the concrete material is more than 3 hours, meeting the requirements of building fire protection codes and effectively delaying the spread of fire.

III. Significantly Improved Construction Efficiency

Compared with traditional brick-concrete structures, the construction period of prefabricated cement houses is greatly shortened:

• Factory prefabrication: Components are produced in a standardized manner in the factory, ensuring quality control and reducing on-site wet operations.
• On-site assembly: The overall installation of a 100-square-meter house only takes 1 day, shortening the construction period by about 90% compared with traditional construction methods. It is especially suitable for emergency housing or seasonal construction needs.

IV. Multiple Performance Advantages

• Durability: The designed service life of the house is more than 70 years. The concrete structure is resistant to weathering and corrosion, with low maintenance costs.
• Adaptability: It has functions such as thermal insulation and energy conservation, wind and moisture resistance, and can adapt to different climatic regions.
• Flexibility: It supports overall relocation or secondary disassembly and assembly, and the components can be reused, reducing resource waste.

V. Application Scenarios

This type of housing is suitable for various scenarios such as rural self-built houses, temporary housing, tourist homestays, and post-disaster reconstruction, especially for projects with high requirements for construction period and safety. The practice in Tongliang Tuqiao Town shows that its cost-effectiveness and practicality have been recognized by the market.
