Five-Meter Prefabricated House

The following are suitable house-building plans and related parameters of prefabricated panels for a 5-meter span:

I. House-building plans for a 5-meter span

1. Single-story flat-roofed house

   • Structural type: Brick-concrete or light steel structure.
   • Features: Mature construction techniques; the roof can double as a drying platform or for installing solar panels; short construction period.
   • Suitable scenarios: Rural self-built houses, warehouses, workshops, etc.

2. Light steel keel movable house

   • Structural type: Factory-prefabricated standardized components assembled on-site.
   • Features: Fast construction speed; can be disassembled and relocated; high reuse rate; suitable for temporary or rapid housing needs.
   • Suitable scenarios: Emergency housing, temporary housing on construction sites, etc.

3. Traditional sloped-roof tiled house

   • Structural type: Double-sloped roof with main load-bearing members being wooden or steel beams.
   • Features: High drainage efficiency; suitable for areas with high annual precipitation; no additional pillars needed for a 5-meter span, providing spacious interiors.
   • Suitable scenarios: Residences in rainy areas, rural bed-and-breakfasts, etc.

4. Container-modified house

   • Structural type: Two standard containers placed side by side (close to a 5-meter span).
   • Features: Cohesive interior space; ready to use upon purchase; strong earthquake resistance; can be hoisted and relocated as a whole.
   • Suitable scenarios: Low-cost bed-and-breakfasts, mobile offices, temporary exhibition halls, etc.

II. Related parameters of prefabricated panels

1. Length of prefabricated floor slabs for commercial housing

   • Common lengths are 4200 mm, with special specifications of 3800 mm; no standard prefabricated panels over 5 meters.
   • For a 5-meter span, customization or other structural forms (such as cast-in-place concrete, steel beams, etc.) are required.

2. Load-bearing capacity of 5-meter prefabricated panels

   • Load-bearing capacity per unit area: 400 kg/m² - 600 kg/m².
   • Maximum load-bearing capacity for 5 square meters: 3000 kg (calculated at 600 kg/m²).
   • Precautions: Load-bearing capacity is affected by factors such as materials, span, and support conditions; it must be calculated based on specific designs.

III. Suggestions for plan selection

• If rapid construction is pursued and the budget is limited, light steel keel movable houses or container-modified houses are preferred.
• If long-term use and high space utilization are required, single-story flat-roofed houses or traditional sloped-roof tiled houses are more suitable.
• If 5-meter span prefabricated panels are needed, confirm whether they are custom products and strictly calculate load-bearing safety.
