Leling Concrete Prefabricated Housing

Leling City has developed a systematic model for the construction of concrete prefabricated housing (prefabricated rural houses), achieving remarkable results, which are reflected in the following aspects:

I. Construction Model and Large-Scale Achievements

Leling City has innovatively constructed a five-in-one model of 'demonstration-driven + demand-oriented + technology-empowered + policy-coordinated + service-oriented', promoting the deep integration of prefabricated technology with rural housing construction. As of now, the city has cumulatively built approximately 830 prefabricated rural houses, covering a total area of about 96,000 square meters and spanning over 610 villages. Typical projects include more than 270 demonstration houses in Zhaogutun Village, Huangjia Town, and Gaoxiayan Village, Zhuji Town, as well as whole-village contiguous modern livable rural houses such as Kongfu Jiayuan (170,000 square meters) and Cuiliu Community (30,000 square meters). In 2023, two new prefabricated dilapidated house renovation pilot projects were added in Tiying Town, further expanding the application scenarios.

II. Technology Empowerment and Process Breakthroughs

1. Structural Innovation: The self-developed cold-formed thin-walled steel-concrete structural system has a seismic fortification intensity of 8 degrees and has been applied in more than 270 rural houses, significantly enhancing housing safety.
2. Process Optimization: The adoption of prefabricated integral concrete frame technology has achieved an 85% factory prefabrication rate for components such as prefabricated columns and composite beams, with the main structure封顶 taking only 15 days. This represents a 60% reduction in construction time compared to traditional methods and a 30% reduction in overall costs.

III. Policy Coordination and Cost Control

1. Planning Constraints: Aligning with village planning, the area of homesteads is strictly controlled to avoid disorderly construction.
2. Cost Reduction: Through a model of 'enterprise concessions + government support', the construction costs for farmers have been reduced. Additionally, more than 160 rural construction craftsmen have been trained, and three model house observation activities have been organized to enhance villagers' awareness and acceptance.
3. Promotion Pattern: Taking the prefabricated dilapidated house renovation pilot projects as a starting point, a large-scale promotion mechanism of 'government guidance, enterprise participation, and voluntary participation by the masses' has been established.

IV. Service-Oriented Approach and Quality Assurance

1. Professional Support: An expert service team of 'Party building + one village, N teachers' has been formed, with on-site designers and engineers providing free design, drawing modifications, and technical consultations, among other 'one-stop' services.
2. Quality Supervision: Comprehensive quality and safety inspections are conducted throughout the entire process, covering key nodes such as foundation and substructure, wall masonry, ring beam and constructional column settings, roof truss and roofing, and final acceptance.
3. Material Guarantee: Enterprises such as Leling Tongyuan Concrete Group Co., Ltd. provide concrete prefabricated components and other building materials. The housing and urban-rural development bureau implements full-chain quality traceability through 'electronic ID cards', strengthening the efficiency of project supervision.

Through triple guarantees of technology, policy, and service, Leling City has promoted the upgrading of concrete prefabricated housing towards safety, energy efficiency, aesthetics, and efficiency, providing a replicable modern solution for rural housing construction.
