Prefabricated House Mold Drawings

Prefabricated house mold drawings are key technical documents that guide the production of prefabricated house components, covering mold design parameters and structural details for core components such as composite slabs and concrete walls. The following provides an explanation from three aspects: drawing types, design features, and application scenarios:

I. Prefabricated Composite Slab Mold Drawings
This drawing (ID: 772636) is created using the AutoCAD2004 platform, with a file format of dwg, primarily used for the production of composite slabs in component factories. Composite slabs are composed of prefabricated slabs and cast-in-place reinforced concrete layers, and the mold design must meet the requirements for bidirectional stress. The drawing clearly specifies parameters such as mold dimensional tolerances, depth of reinforcement positioning slots, and draft angles to ensure precise interlocking between the prefabricated slabs and the cast-in-place layer. Such molds are suitable for high-rise buildings and large-span structures, offering advantages in improving construction efficiency through industrial production while reducing on-site wet work. Note that this drawing can only be obtained through point redemption on a professional design platform.

II. Prefabricated Concrete Wall Steel Mold Drawings
The drawing (ID: 1822762) is available in dual versions: AutoCAD2004 (dwg format) and Solidworks2016 (sldasm/sldprt formats), supporting collaborative design between 3D modeling and 2D engineering drawings. The mold structure incorporates three innovative features:

1. Trapezoidal Base at the Bottom: Increases contact area to enhance mold stability, preventing displacement caused by concrete lateral pressure during pouring;
2. Removable Grooves: Facilitate the cleaning of concrete residues, extending the mold's service life;
3. Convex-Concave Structure at Wall Connections: Enhances the integrity between prefabricated walls and cast-in-place structures through tongue-and-groove design, improving seismic performance.
   Such molds are suitable for the production of shear walls in prefabricated buildings and require payment for downloading the complete drawing.

III. Technical Features of Cement Mobile Home Molds
The third-generation cement mobile home mold breaks free from traditional fixed-size limitations, supporting modular customization ranging from a minimum of 3m × 6m to a maximum of 3.6m × 7.2m, adjustable in 10cm increments to meet diverse residential needs. The mold design focuses on solving two major technical challenges:

1. Crack Prevention Technology: Controls concrete shrinkage stress by optimizing steel mold thickness (usually ≥8mm) and reinforcing rib layout;
2. Surface Finish: Uses electroplated hard chromium treatment on the mold cavity surface to reduce demolding resistance and ensure crack-free house walls.
   Such molds must be used in conjunction with low-heat-of-hydration cement to further reduce the risk of cracking.

Acquisition Recommendations: The above drawings are all sourced from professional design platforms. It is recommended to select the appropriate version based on project requirements. For complex components (such as concrete walls), prioritize using Solidworks 3D drawings for intuitive interference checks; for composite slab molds, the AutoCAD version can be chosen to reduce costs. Before downloading, confirm the platform's point redemption rules or payment standards to avoid subsequent disputes.
