Prefabricated Integral House Mold Design
The design of prefabricated integral house molds should focus on structural strength, modular adaptability, functional integration, weather resistance, and scenario-specific requirements, combined with technological upgrades to achieve efficient production.
I. Structural Strength and Material Selection
The mold body is made of Q235 low-carbon steel or hot-rolled steel plates with a thickness of 6-12mm. The durability is enhanced through CNC cutting, precision welding, and surface treatments such as rust removal and painting. These materials can withstand the high-pressure impact during concrete pouring and are less prone to deformation or cracking over long-term use. Some designs incorporate modular splicing or precision snap-fit structures to enhance sealing, preventing slurry leakage and ensuring the flatness of component surfaces.
II. Modularity and Size Adaptability
The mold adopts a modular splicing structure, supporting the assembly of single sets into standard sizes such as 3m×6m and 4m×8m, with a splicing accuracy of ±0.5mm, reducing the need for secondary plastering on-site. Customized irregular modules (e.g., with window and door openings) or composite structures (e.g., insulated wall panels) can also be produced to meet different architectural requirements. Modular design facilitates transportation and storage, enhancing construction flexibility.
III. Functional Integration and Operational Convenience
The mold is internally pre-fitted with pipeline openings to accommodate electrical and plumbing installations, reducing the need for on-site slotting. It is equipped with lifting lugs for easy handling by lifting equipment, enabling a four-person team to complete the prefabrication of three components per day. Some designs incorporate user-friendly features such as sliding rails and hydraulic systems, reducing labor intensity and increasing mold removal speed by over 30%.
IV. Weather Resistance and Turnover Efficiency
The mold can operate stably in environments ranging from -30℃ to 70℃. Steel molds can achieve 300-1500 turnover cycles per set (more than twice that of plastic molds), resulting in lower long-term costs. Steam curing processes accelerate concrete hardening, shortening production cycles by 20%-40% and further improving turnover efficiency.
V. Scenario-Based Design Practices
Taking prefabricated residential projects as an example, molds need to be customized based on design drawings to include multi-functional embedded parts, enabling rapid connection between wall panels and equipment pipelines and reducing on-site construction time by over 50%. Structural optimization also minimizes concrete waste, aligning with energy conservation and emission reduction goals.
VI. Technological Upgrade Directions
Molds have undergone four generations of iteration: from simple structures to vertical wall forming, then to multi-size adjustment and fully automated hydraulic system integration. Current mainstream molds feature electric vibration functions and support centralized prefabrication of components, further shortening construction cycles.
