Xuzhou Zhongmei Hitech International Engineering Co., Ltd. recently obtained a utility model patent (No. ZL 2024 2 0480278.2) for “A Prefabricated Composite Exterior Wall Panel Structure,” addressing insulation, installation, and safety challenges in prefabricated buildings. This breakthrough strengthens the company’s leadership in green construction technology.

Key Technical Innovations

Efficient Insulation: Four-layer design (decorative layer, vacuum insulation, steel framework, inner insulation) cuts thermal conductivity to 0.25W/㎡·K, 30% better than traditional panels, meeting cold-region energy standards.

Rapid Assembly: Tongue-and-groove plus screw connections reduce installation time to 15 minutes per panel, 50% faster than welding, minimizing high-altitude work.
Structural Safety: Wind resistance (1.5kPa) and 8-degree seismic adaptability, with pre-embedded slots to avoid post-construction damage.

Market Impact

Cost & Time Savings: Shortens 30,000㎡ project construction period by 40 days, saving ~¥1.2M in labor; factory-precision (2mm error) eliminates cracks/leaks.
Policy & Comfort: Meets national prefabrication standards (assembly rate ≥60%) and boosts indoor comfort with 50% less temperature fluctuation.

Private Enterprise Innovation

As a "Little Giant" enterprise, the patent reflects its problem-solving R&D:
Collaborated with China University of Mining and Technology to solve insulation bonding issues.

Achieved 18-month patent-to-production cycle, 30% faster than industry average.17th patent in its prefabricated building portfolio, offering full-chain solutions.
