Cement Prefabricated House - 3 Floors

The construction plan for a three-story cement prefabricated house covers project overview, construction process, technical key points, and more. It offers advantages such as fast construction, low cost, minimal waste, and reliable quality, and has been applied in scenarios like rural villas and scenic area homestays.

I. Project Overview
The three-story cement prefabricated house adopts a modular design. Each module typically measures 6 meters in length, 3.3 meters in width, and 3 meters in height, with the specific quantity determined by project requirements. The building structure is a prefabricated reinforced concrete full-frame shear wall system, designed for a service life of 50 years and capable of withstanding seismic intensities up to 7 degrees, meeting the safety needs of most regions.

II. Construction Process

1. Factory Prefabrication: The entire process, including steel bar tying, mold assembly, and concrete pouring, is carried out mechanically on standardized production lines. Each module takes approximately 7 days to produce, with errors controlled within 2 millimeters to ensure component precision.
2. On-site Hoisting: After being transported to the construction site, the modules are hoisted using a 50-ton crane in conjunction with an intelligent positioning system. The installation of the main structure for a single building takes only 4 hours. For example, the on-site installation of 9 prefabricated cement houses took about 3 hours, significantly more efficient than traditional construction methods.

III. Technical Key Points

1. Structural Stability: The full-frame shear wall structure is used, with wall thickness and reinforcement ratio adjusted according to design requirements. Modules are connected using pre-stressed bolts and antique-style mortise-and-tenon joints to enhance overall seismic performance.
2. Energy Efficiency and Environmental Protection: Insulation layers are embedded in the walls, and interfaces for solar panels are reserved on the roof to improve building energy efficiency. Construction waste is reduced from 30 tons per building in traditional methods to 0.5 tons, a reduction of 98%.
3. Reliable Quality: Factory prefabrication ensures stable component quality, and on-site assembly reduces construction errors, resulting in overall building quality superior to traditional methods.

IV. Advantages and Characteristics

1. Fast Construction Speed: While traditional construction for a 300㎡ house takes 6 months, the main structure of a prefabricated cement house can be hoisted in just 1 day, significantly shortening the overall construction period.
2. Low Cost: For a 100㎡ house, labor costs are reduced from 60,000 yuan in traditional methods to 24,000 yuan, a decrease of 60%.
3. Wide Application: It has been successfully used in rural villas (e.g., the Kaifeng Tongxu project, where the main structure was hoisted in 1 day), scenic area homestays (e.g., the Luoyang Luanchuan project, completed in 7 days), and village and township public service facilities (e.g., the Shangqiu Suiyang District Party-Mass Service Center).
