Installation of Doors for Prefabricated Houses

There are various ways to install doors for prefabricated houses, and appropriate solutions can be selected based on materials, scenarios, and requirements, as detailed below:

I. Installation of Prefabricated Assembly-Type Gatehouses in Rural Areas

1. Steel Structure Assembly-Type Gates:
   • Installation Points: Ensure the foundation bearing capacity is ≥10 tons/m². Fix steel components using welding or bolts. The longest single piece can be disassembled to 6 meters for transportation. After on-site assembly, apply anti-rust paint (every 2 years).
   • Applicable Scenarios: Construction site entrances, new rural construction, and other locations requiring rapid setup, with a delivery cycle of 7-15 days.
2. Stone Gatehouses:
   • Installation Points: Reserve a concrete foundation. Use professional lifting equipment (with a weight capacity of up to 40 tons). Freight costs are approximately 200-500 yuan/ton. The surface requires waterproofing treatment every 5 years.
   • Applicable Scenarios: Landmark buildings at village entrances, reflecting regional culture, with a carving cycle of 30-60 days.
3. Mixed-Material Gatehouses:
   • Installation Points: Combine granite with relief craftsmanship. The manufacturer provides on-site installation services, balancing aesthetics and weather resistance.

II. Installation of Prefabricated Villa Assembly-Type Gatehouses Using Gatehouse Molds

• Process Flow:
  1. Laser-cut steel sheets to create traditional pattern steel molds. Remove air bubbles during concrete pouring to ensure density.
  2. After mold removal, use a laser instrument to calibrate verticality. The position of the plaque follows the ancient rule of 'left illumination, right solemnity'.
  3. Incorporate an internal steel reinforcement framework to enhance seismic resistance, suitable for villa projects with high structural safety requirements.

III. Rapid Installation of Doors for Self-Built Houses

• Modular Installation Method:
  1. Precisely excavate the foundation pit and place prefabricated concrete foundation piers (utilizing their load-bearing capacity).
  2. Directly erect the gate without complex foundation treatment, suitable for self-built house projects with tight schedules.

IV. Rapid Installation of Prefabricated Door Frames

• Operating Steps:
  1. Embed the prefabricated door frame into the wall opening. Use wooden blocks to support and adjust the levelness and verticality (using a level for calibration).
  2. Fix the door frame by penetrating expansion screws through its borders to ensure smooth door operation and avoid sealing issues caused by installation deviations.

Purchase and Maintenance Recommendations:

• For steel structure gatehouses, prioritize models that can be disassembled for transportation to reduce logistics costs; for stone gatehouses, plan the carving cycle in advance.
• Regular maintenance (such as repainting steel structures and waterproofing stone surfaces) can extend service life and reduce the frequency of later repairs.
