Product Description
Prefabricated Buildings (PEB) - Efficient Building Solutions in the Industrial Era
Ⅰ. Core Definition and Technical Logic
Prefabricated Building (PEB) is a construction model achieved through factory prefabrication+on-site assembly :
-Pre design: Complete structural design in the factory, fully considering regulatory requirements, load conditions (such as gravity, wind, earthquake loads), and building functional requirements;
-Prefabricated production: Processing steel frames, walls, roofs and other components into precise sizes, and synchronously completing pre-treatment such as anti-corrosion and insulation;
-On site assembly: After the components are transported to the site, they are quickly assembled through methods such as bolts and welding, greatly reducing the construction period.
Key technical optimization: By matching the geometric shape of the frame with the bending moment diagram, precise allocation of material strength is achieved, reducing redundant materials and reducing the self weight of the structure by 10% -30%, while maintaining optimal mechanical performance.
Ⅱ. Technological progress and core advantages
1. Efficiency Revolution
-Duration compression : The on-site construction period is 50% -70% shorter than traditional buildings, especially suitable for emergency projects or large-scale project clusters;
-Cost controllable : Standardized production in the factory reduces manual errors and material waste, resulting in a comprehensive cost reduction of 20% -40%.
2. Performance Upgrade
-Material Innovation : Using high-strength steel (such as Q355B) and energy-saving sandwich panels (rock wool/polyurethane) to meet diverse needs such as fire prevention, earthquake resistance (fortification intensity ≤ 9 degrees), and thermal insulation;
-Aesthetic compatibility : The appearance can be selected with various finishes such as color steel plates and glass curtain walls, suitable for personalized design in industrial plants, commercial complexes, cultural and sports venues, and other scenes.
3. Sustainability
-Green Construction: Reducing construction pollution by 90% and approaching zero construction waste emissions;
-Recycling : The main structure can be disassembled and reorganized, with a steel recovery rate of over 90%, in line with the "dual carbon" goal.
III. Application Scenarios
-In the industrial sector, workshops, warehouses, and logistics centers (such as e-commerce intelligent warehousing bases) utilize large-span column free spaces to improve equipment layout efficiency;
-Commercial and public buildings : Exhibition halls, sports halls, supermarkets (such as large chain stores), enhance spatial experience through flexible zoning and transparent design;
-Special scenarios: Post disaster reconstruction of housing, temporary medical facilities, oil field camps, relying on rapid deployment capabilities to respond to emergency needs.
Ⅳ. Industry Development and Future Trends
-Technology Integration : Combining with BIM (Building Information Modeling) to achieve full process digital management from design, production to operation and maintenance;
-Intelligent Upgrade: Integrating photovoltaic roofs, intelligent ventilation systems, and energy management platforms to create "net zero energy" buildings;
-Globalization Popularization: Rapid promotion in developing countries (such as Southeast Asia and Africa) due to cost and efficiency advantages, while expanding high-end markets through customized design in developed countries (such as Europe and America).
Ⅴ. Summary
Prefabricated buildings (PEB) reconstruct the construction process with industrial thinking, breaking the time and cost bottlenecks of traditional construction modes, while improving building performance through material optimization and technological innovation. With the surge in global demand for green buildings and efficient infrastructure, PEB is becoming the core direction of the construction industry's transformation, leading the new generation of construction revolution of "design standardization, production factory, and installation modularization".
