Linyi Prefabricated Houses

The following is information about prefabricated houses in Linyi:

Manufacturers: As of December 17, 2024, there are 92 manufacturers of cement prefabricated houses in Linyi, indicating that the local prefabricated housing industry has formed a certain scale and has a relatively complete supply chain system.

Construction Plan Features:

1. Policies and Standards: Linyi City has specified that the proportion of prefabricated buildings should reach 35% by 2025. The demonstration project in the Yihe New Area requires a prefabrication rate of no less than 60% and an assembly rate exceeding 75%, aligning with the national trend of green building development. The project quality objectives include a structural safety grade of II, a seismic fortification intensity of 7 degrees, a main structure lifespan of no less than 50 years, and a construction period of only 30 days (including component production, transportation, installation, and acceptance), demonstrating high efficiency.
2. Component Types and Parameters: The main prefabricated components include composite floor slabs (2.4m×6m, with a thickness of 60mm + a 70mm cast-in-place layer), prefabricated exterior wall panels (including integrated insulation, with a thickness of 200mm), prefabricated stairs (plate-type, with a tread width of 260mm), and lightweight partition panels (with a thickness of 120mm and a unit weight of ≤800kg/m³). Component production utilizes local industrial bases, with a transportation radius of ≤50km, ensuring timeliness and cost control.
3. Construction Process Specifications: Site preparation involves compaction with 200mm thick graded gravel, with a foundation bearing capacity of ≥150kPa. Measurement and layout errors are controlled within ±3mm. Components entering the site must be accompanied by acceptance certificates, concrete strength reports (≥C30), steel reinforcement cover thickness (allowable deviation of +5mm/-3mm), and embedded part position deviations (≤10mm). Storage requirements are strict, such as storing composite floor slabs vertically, exterior wall panels at a 30° incline, and stacking height of ≤3 layers.

Construction Examples: There are already cases of rapid assembly of prefabricated houses in Linyi, such as a two-story villa that can be assembled in just 4 hours, highlighting the modular and standardized advantages of prefabricated houses, which are suitable for emergency housing, tourism resorts, and other scenarios.

Technical Team and Equipment: The project is equipped with a second-class registered constructor in municipal engineering and a technical leader with more than 5 years of experience. Full-time safety officers are certified and equipped with smart safety helmets. Construction equipment includes 25t truck cranes and concrete mixing stations, ensuring construction safety and efficiency.
