Xicheng Prefabricated Concrete House Molds

Xicheng prefabricated concrete house molds are primarily applied in concrete modular construction technology, combining factory prefabrication with on-site assembly to achieve an efficient, precise, and environmentally friendly construction model, providing innovative solutions for the renovation of urban dilapidated buildings.

I. Core Application Scenarios

The renovation project of Building 28 in Sanlihe Area 1, Xicheng District, serves as a typical example. It adopts modular prefabricated construction technology, dividing the building into 156 prefabricated module units. Each module is an independent steel structure unit, integrating walls, doors, windows, and some pipelines in the factory before being transported to the site for assembly. From the first module hoisting to the topping-out, it took only 46 days, significantly shortening the construction period. This type of technology is particularly suitable for the renovation of dilapidated buildings, reducing on-site construction risks through standardized design while minimizing disturbances to surrounding residents.

II. Technical Feature Analysis

1. Industrial Production
   The molds complete the prefabrication of concrete components (such as walls and floor slabs) in the factory, forming a casting cavity through mold opening and closing, combined with steam curing processes to accelerate hardening. This process achieves controllability of the production environment, avoiding the impact of weather on on-site wet work while enhancing the quality stability of the components.

2. Modular Design
   The molds support multi-size adjustments (such as third-generation molds) or fully automatic hydraulic systems (fourth-generation molds), enabling the production of different housing module types. For example, the Huapichang Hutong No. 8 project utilized concrete modular integrated construction technology, completing 90% of the processes in the factory, with only module connections required on-site, adapting to diverse architectural needs.

3. Precision and Efficiency
   The molds are made of high-strength steel (such as Q345B), achieving a precision of ±1mm, with over 300 reuses and a lifespan of approximately 5-8 years. High-precision molds ensure consistent component dimensions, reducing on-site adjustment time, while the long lifespan design lowers long-term costs.

4. Environmental Protection and Economy
   Factory-based production reduces waste of disposable materials such as wood and minimizes dust and noise generated by on-site wet work. The Huapichang Hutong No. 8 project shortened the original 15-month construction period to 3 months through this technology while reducing pollution to the surrounding environment, aligning with green construction principles.

III. Value of Typical Cases

Renovation projects of dilapidated buildings in Xicheng District (such as Building 28 in Sanlihe Area 1 and Huapichang Hutong No. 8) demonstrate that prefabricated concrete house mold technology, through the 'factory prefabrication + on-site assembly' model, can achieve the triple goals of shortened construction periods, improved quality, and optimized environmental protection, providing efficient and safe solutions for urban renewal.
