Specifications of Prefabricated Concrete Houses

The specifications of prefabricated concrete houses vary depending on the type and design requirements. Common types include prefabricated concrete assembled houses, prefabricated concrete integral houses, and modular prefabricated cement houses. The specific specifications are as follows:

Prefabricated Concrete Assembled Houses

These houses are assembled on-site using prefabricated components, offering high flexibility in specifications.

• Single-story houses: The length ranges from a few meters to tens of meters, the width is typically between 3-6 meters, and the height is generally 2.5-5 meters. For example, a small temporary house may adopt a specification of 6m×3m×2.5m, while a large warehouse may extend to 30m×6m×5m.
• Two-story houses: The length is comparable to that of single-story houses, with a total height typically between 4-6 meters and a floor height of 2.5-3 meters for each story. For example, a rural self-built house may adopt a specification of 10m×5m×6m (two stories, 3 meters per story).
• Three-story houses: The length is the same as that of two-story houses, with a total height of 6-9 meters and a floor height of 2.5-3 meters per story. These specifications are often used for commercial offices or dormitories, requiring compliance with structural stability requirements.

Prefabricated Concrete Integral Houses

These houses are prefabricated as a whole and then transported to the site for installation, with relatively fixed dimensions.

• Common dimensions: The length is approximately 6-12 meters, the width is approximately 3-6 meters, and the height is approximately 2.5-3.5 meters. For example, a specification of 6m×3m×2.8m is suitable for a temporary office on a construction site, while a specification of 12m×6m×3.5m can be used for a small community activity center.

Prefabricated Cement Houses (Modular Design)

These houses are based on standardized modules and support customized adjustments.

• Standard dimensions:
  • 3m×6m: Suitable for small temporary houses, such as construction site guard rooms or farm tool rooms.
  • 4m×8m: Medium-sized, often used for rural self-built houses or small shops, meeting basic residential or commercial needs.
  • 5m×10m: Larger space, suitable for family homes or commercial buildings, with multiple functional areas that can be divided internally.
• Customized dimensions:
  • Width: Typically within the range of 3-4 meters, adjustable in increments of 10 centimeters (e.g., 3.1m, 3.2m), with special requirements expandable to 7.2m or 7.6m.
  • Length: Adjustable according to site conditions, such as a customized length of 6.6m outer diameter, supporting the splicing of longer dimensions.
  • Other parameters: Height and number of stories (single-story or double-story) can be customized, requiring design considerations based on structural safety and usage functions.

Selection criteria: Purpose (standard dimensions are preferred for temporary houses, while customized dimensions are preferred for long-term residence or commercial use), site constraints (precise width control is required for narrow sites), and cost and efficiency (standard dimensions have a short production cycle and low cost, while customized dimensions require additional design fees but can precisely match needs).
