Factory Building Prefabrication in Puyang

The prefabrication practice of factory buildings in Puyang focuses on cement movable houses and packing-box houses, enhancing construction efficiency and building quality through industrial production models.

Cement Movable Houses: Industrial Upgrading of Traditional Craftsmanship Puyang County Tiangong New Building Materials Co., Ltd. produces cement movable houses using traditional reinforced concrete pouring techniques, but achieves efficiency improvements through industrial methods. Key features include:

1. Structure and Performance: Integrated reinforced concrete pouring forms a sturdy structure, with each house having a fixed area of 21.6 square meters, strong earthquake resistance, a design life exceeding 60 years, and significant economic benefits.
2. Modular Design: Supports diverse design requirements, with house components that can be quickly assembled and disassembled, adapting to temporary or permanent building scenarios, and reducing on-site construction time and labor costs.
3. Quality Controllability: Standardized factory production ensures uniformity in key parameters such as concrete mix ratios and steel bar layouts, avoiding quality fluctuations associated with traditional on-site construction.

Packing-Box Houses: Innovative Applications of Modular Construction Packing-box houses reconstruct the traditional construction process by prefabricating core components in factories and assembling them quickly on-site:

1. Production and Transportation Advantages: The main structure is manufactured to standard specifications in factories, with minimal impact from weather conditions and high quality stability; transported as independent 'units' to reduce logistics costs.
2. Improved Construction Efficiency: Modular design enables mass production of standardized components, reducing on-site wet work (such as concrete pouring), shortening construction periods by over 50%, and reducing construction waste by 80%.
3. Functional Flexibility: Internal spaces can be customized according to needs, with multiple boxes combinable through stacking or parallel connection to meet diverse scenarios such as offices, residences, and warehouses; disassembled and reused, with a resource recycling rate of 90%.
4. Green Sustainability: Factory production reduces energy consumption, with material recyclability higher than traditional buildings; modular design supports full building lifecycle management, aligning with low-carbon development requirements.

Technical Value and Social Significance Both prefabricated housing models reflect the trend of building industrialization: cement movable houses balance cost and durability through the industrial transformation of traditional craftsmanship; packing-box houses drive buildings towards 'movable and recyclable' evolution through modular design. Puyang's practice provides efficient solutions for temporary buildings, emergency shelters, construction site housing, and offers a replicable model for energy conservation, emission reduction, and resource optimization in the construction industry.
