Prefabricated Housing Finished Products in Liaoyuan City

The prefabricated housing finished products in Liaoyuan City mainly consist of integrated housing and prefabricated modular buildings, characterized by efficient construction, superior performance, intelligent integration, and significant cost-effectiveness.

Efficient and Flexible Construction Methods: A combination of factory prefabrication and on-site assembly is employed, transferring a large amount of wet work to the factory and reducing dependence on the on-site environment and climate. For example, by using cranes to embed prefabricated wall panels into steel frames, the main structure of a two-story building can be completed within three days, significantly improving construction efficiency.

Outstanding Material Characteristics:

• Lightweight and High Strength: The weight of the light steel frame structure is only 1/5 of that of brick-concrete buildings, with wind pressure resistance doubled. The aluminum-zinc coating ensures that the steel does not become brittle at -30°C, resulting in an excellent strength-to-weight ratio for the overall structure.
• Strong Thermal Insulation: The thermal insulation effect of a 10 cm thick rock wool board is equivalent to that of a 1-meter thick brick wall, and the integrated insulation layer of sandwich panels further enhances thermal performance.
• Significant Environmental Protection: Construction waste is reduced by 70%, and offcuts can be recycled into sound insulation pads, achieving resource recycling.

Comprehensive Performance Advantages:

• Shortened Construction Period: The construction period is compressed to 1/3 of traditional methods, with the construction period for a 120-square-meter residence shortened from six months to within two months.
• Improved Precision: Factory prefabrication improves construction precision from the centimeter level to the millimeter level, reducing decoration material waste by more than 15%.
• Strong Adaptability: Modular design supports flexible spatial combinations, with components that can be disassembled, reorganized, or recycled to meet functional expansion needs (such as adding a sunroom).

High Level of Intelligence and Integration:

• Energy Systems: Roof photovoltaic panels and energy storage systems meet 60% of daily electricity needs, while ground-source heat pumps and air-source heat pumps complement each other to reduce energy consumption. Rainwater collection and gray water treatment form a local water cycle.
• Construction Management: Building Information Modeling (BIM) technology optimizes exterior wall thermal parameters, while Radio Frequency Identification (RFID) chips track component status in real-time, forming dynamic construction records.

Obvious Cost-Effectiveness: The cost of a 120-square-meter residence is controlled at 1500-1600 yuan/square meter, lower than the 1800 yuan/square meter for traditional brick-concrete structures. Additionally, completing the project one month earlier can save thousands of yuan in rental expenses.

Rich Application Cases: Liaoyuan Yinji Garden adopts prefabricated panel building technology to improve construction efficiency and quality; a pilot project in the suburbs consists of 30 integrated residences forming a micro-community, verifying the technical feasibility.
