Zhangzhou Cement Prefabricated House
Zhangzhou cement prefabricated houses, primarily featuring prefabricated structures, are characterized by safety, efficiency, and cost control, making them suitable for rapid construction scenarios.
1. Procurement Project Examples
The Longshan Detachment of the Traffic Police Brigade of the Nanjing County Public Security Bureau once procured prefabricated cement houses through competitive negotiation. The project number was ZZZX(2024)TP028, with a budget of 410,125 yuan, requiring delivery and installation to be completed within 30 days after contract signing. This project explicitly targeted procurement from small and medium-sized enterprises (SMEs), requiring suppliers to provide SME declaration letters and not accepting joint bids. Such procurement cases indicate that cement prefabricated houses have achieved standardized application conditions in the public facilities sector.
2. Outstanding Structural Safety Performance
Prefabricated cement houses adopt a 'full-frame shear wall' design, with the core structure constructed using Φ10-Φ14 national standard threaded steel bars as the framework, combined with C35 concrete for integral pouring. Each module weighs over 20 tons, with wall thicknesses ranging from 150-200mm and floor slab thickness of 120mm, forming a high-strength load-bearing system. Their seismic performance reaches a design intensity of 7 degrees, capable of withstanding magnitude 8 earthquakes; wind resistance is achieved through pre-stressed bolt connections between modules, ensuring structural stability under 12-level typhoons. For example, during Typhoon Yagi's passage through Zhangzhou in 2024, a cement house homestay withstood 11-level winds without damage to its exterior walls or roof. Additionally, the concrete's fire resistance limit exceeds 3 hours, meeting fire safety requirements.
3. Significant Advantages in Construction Efficiency and Cost
Traditional brick-and-mortar self-built houses require 3-6 months for construction, whereas cement prefabricated houses significantly shorten the timeline through a 'factory production + on-site assembly' model. During the prefabrication stage, a single module (30㎡) takes only 7 days to complete steel bar binding, mold assembly, and concrete pouring, unaffected by weather conditions; during the installation stage, a 50-ton crane with 3 workers can complete the lifting of a single module in 4 hours, with the entire installation of a 100㎡ house taking only 1 day, reducing the construction period by 90% compared to traditional methods. In terms of cost, a 120㎡ rural self-built house using a prefabricated cement house as the main structure costs 120,000-150,000 yuan, saving 30% compared to traditional brick-and-mortar structures; the construction period is 3 days, saving 97.5%; and construction waste is only 1.5 tons, a 90% reduction. Modules come pre-installed with water and electricity pipelines, allowing for immediate use upon connection on-site, achieving 'installation today, occupancy tomorrow.'
4. Application Scenarios and Policy Support
Cement prefabricated houses are suitable for rural self-built houses, temporary buildings, public facilities, and other fields, with their modular design supporting flexible assembly to meet different area requirements. At the policy level, government procurement projects explicitly support SME participation, promoting the popularization of prefabricated building technology and providing policy guarantees for the development of the cement prefabricated house market in the Zhangzhou area.
