Prefabricated House Construction in Qixian
The construction of prefabricated concrete houses in Qixian, Henan Province, is characterized by rapid speed, advanced methods, low cost, reliable technology, and convenient application.
Extremely Fast Construction Speed: At the construction site in Qixian, a crane lifts a 30-ton concrete module, enabling the main structure of a three-story villa covering 200 square meters to take shape in just 4 hours. A 100-square-meter house can be ready for occupancy in only 5 days from a bare plot of land, significantly shortening the construction cycle and demonstrating remarkable 'Chinese speed'.
Advanced Construction Method: A combination of factory prefabrication and on-site lifting is employed. Inside the factory, the entire process, including steel bar tying, mold assembly, and concrete pouring, is mechanized. The production cycle for a single module is only 7 days, with an error margin controlled within 2 millimeters, ensuring high precision of the modules. On-site, a 50-ton crane, in conjunction with an intelligent positioning system, completes the installation, enhancing construction efficiency and accuracy.
Significant Cost Advantage: The cost per square meter of a prefabricated concrete house is approximately 300 yuan. For a 300-square-meter house, the total cost is less than 100,000 yuan, significantly lower than traditional construction costs, saving a substantial amount of money for homebuilders.
Reliable Technical Guarantee: The full-frame shear wall structure utilizes C35 concrete and Φ14 threaded steel bars, with a reinforcement ratio of 1.2% per module. The wall thickness is 200mm, and the compressive strength reaches 30MPa, ensuring the sturdiness of the house. Modules are connected using both mortise-and-tenon joints and bolts, resulting in an overall displacement of only 3cm during a simulated 9-degree earthquake, demonstrating excellent seismic resistance.
Convenient Practical Application: On December 28, 2022, prefabricated houses were installed in rural areas of Qixian. Their modular assembly method transformed the construction process from a traditional 'marathon' into a轻松游戏 (easy game, similar to 'building with blocks'), reducing construction difficulty and improving efficiency.
