How Xiao Wang Does Prefabricated Houses

If Xiao Wang is engaged in the prefabricated house business, the core processes typically include modular design, factory prefabrication, logistics transportation, and on-site assembly. Here are the specific details:

1. Modular Design
The core of prefabricated houses lies in dividing the building into independent functional modules (such as bedrooms, kitchens, and bathrooms). Each module must clearly define its dimensions, structure, interfaces, and water and electricity layouts during the design phase. The design stage should take into account customer needs, site conditions, and transportation constraints to ensure that the modules are standardized and can be flexibly combined. For example, module dimensions must comply with the height and width restrictions for road transportation, and interfaces must reserve points for water and electricity connections as well as structural connectors.

2. Factory Prefabrication
Modules undergo full-process production in the factory:

• Steel Structure Welding: Light or heavy steel frames are used, and the main structure is welded using automated equipment to ensure strength and precision.
• Wall Installation: Prefabricated wall panels (such as lightweight concrete panels or metal sandwich panels) are installed, integrating insulation, soundproofing, and fireproofing layers.
• Water and Electricity Pre-embedding: Pipes and wires are embedded in the walls and floors, with reserved interfaces for switches, sockets, and faucets to reduce on-site construction work.
• Interior Decoration: The decoration of floors, walls, and ceilings is completed, along with the installation of fixed furniture such as cabinets and bathrooms.
• Quality Inspection: Modules undergo inspections for structural safety, airtightness, and water and electricity functionality to ensure compliance with building codes.

3. Logistics Transportation
Prefabricated modules need to be transported to the site using specialized vehicles (such as low-bed semi-trailers). Before transportation, routes must be planned to avoid height and width-restricted sections, and modules should be securely fastened and protected to prevent damage from bumps. For oversized modules, they may need to be divided into smaller units or transported in sections and assembled on-site.

4. On-site Assembly

• Foundation Construction: The foundation is poured in advance or prefabricated foundation panels are installed to ensure levelness and load-bearing capacity.
• Module Hoisting: Modules are hoisted to their designated positions in the designed order using cranes and connected through bolts or welding at structural interfaces.
• Water and Electricity Connection: Water pipes and electrical wires between modules are connected, and the system is tested for water and electricity supply.
• Final Touches: Gaps between modules are filled, exterior decorative panels are installed, and outdoor pipelines are laid to complete the final inspection.

It should be noted that if Xiao Wang's business model is similar to that of 'prefabricated fences', it may focus more on lightweight, quickly installed prefabricated houses (such as temporary buildings and mobile houses). In this case, the design process may be simplified, and the emphasis may be on standardizing module production and enhancing on-site assembly efficiency. Specific operations need to be further refined based on the business positioning.
