Prefabricated Panel Structure of Houses in Ningbo

The following is an overview of the prefabricated panel structure of houses in Ningbo:

I. Safety Monitoring of Prefabricated Panel Structures in Old Houses

Liuheng Town in Ningbo has launched a special safety monitoring project for the prefabricated panel structures of old houses. Zhejiang Huazi Structural Design Consulting Co., Ltd. won the bid for the technical service project for the safety monitoring of the prefabricated panel structures of urban multi-hole houses from 2025 to 2026. It will implement dynamic technical monitoring on 125 old houses in the town. By establishing a digital house technology platform and using 3D modeling technology to build a 3D information system, the structural status of houses can be tracked in real time, and potential safety hazards can be identified and eliminated promptly. This monitoring system focuses on ensuring the safety of the main structures of buildings while also taking into account the safety impacts on adjacent buildings. The contract service period is 2 years (subject to the actual signing date). This initiative reflects a systematic emphasis on the safety management of existing houses with prefabricated panel structures.

II. Application of Prefabricated Component Technology in New Residential Communities

Some newly built residential communities in Ningbo, such as CR Land Wucai City Community, Poly Dongjun Community, and Vanke Yungu Community, are constructed using prefabricated component technology. This technology involves the factory-based production of building components (such as prefabricated panels, composite slabs, and stairs), which are then transported to the site for modular assembly. This technology offers three major advantages:

1. Enhanced Structural Performance: Components are produced in a standardized manner in factories, ensuring high quality control and better structural stability compared to traditional cast-in-place processes.
2. Optimized Construction Efficiency: On-site work is reduced by more than 50%, construction periods are shortened by 30%-40%, and worker labor intensity is decreased.
3. Significant Environmental Benefits: It reduces on-site wet work, lowers dust and noise pollution, and aligns with the requirements of green building development. In addition, the prefabricated components have excellent thermal insulation, sound insulation, and fire resistance properties, providing convenient conditions for later maintenance and renovation.

III. Industrial Ecosystem of Prefabricated Components

Ningbo has formed a complete industrial chain for prefabricated components:

1. Cluster of Production Enterprises: Enterprises such as Ningbo Deshi Construction Technology Co., Ltd. in Shiqi Street, Haishu District, produce prefabricated components using concrete and steel bars as the main raw materials. The components have reserved steel bars at the edges for on-site splicing.
2. Diverse Product Types: The range includes composite slabs, prefabricated stairs, PC components, ALC panels, etc., meeting different construction needs.
3. Innovative Service Models: Some enterprises offer differentiated services such as custom-made prefabricated bay windows and exclusive supply of prefabricated stairs, with service areas covering the Yangtze River Delta region. This industrial ecosystem provides technical support and industrial guarantees for the application of the prefabricated panel structure of houses in Ningbo.
