How to Make Prefabricated Houses

There are various ways to make prefabricated houses, with common methods including modular construction, prefabricated component assembly, construction of detachable prefabricated container houses, and prefabricated panel production.

1. Modular Construction Method The entire building is disassembled into independent modules, which are standardized and manufactured in a factory. Each module includes core structures such as ceilings, floors, walls, and water and electricity pipelines. For example, in the CSCEC Hailong Intelligent Construction Industrial Park, ceilings, walls, and bathroom waterproof layers of houses are all prefabricated in the factory. After being transported to the construction site, the modules are quickly assembled into a complete building through mechanical hoisting. This method can significantly shorten the construction period, improving efficiency by over 60% compared to traditional construction. Moreover, the quality is controlled by the factory environment, ensuring higher precision.

2. Prefabricated Component Assembly Method This method is suitable for scenarios such as rural villas and involves assembling on-site based on prefabricated components. The construction process includes leveling the foundation and pouring a cushion layer, installing foundation piles and beams, and using mortise-and-tenon joints for quick connection; hoisting prefabricated stairs and laying a 5-centimeter-thick floor slab; finally, grouting and reinforcing the gaps between all components. For example, a rural project completed the main structure in 14 days using this method. The core advantages lie in the standardization of components and the simplification of the construction process, reducing the amount of on-site wet work.

3. Construction Method for Detachable Prefabricated Container Houses Based on the prototype of a container, rapid assembly is achieved through prefabricated frames and panels. The steps include:

• Bottom Frame Installation: Connect the lower corner fittings with the bottom beams, fix the purlins, measure the diagonals to ensure perpendicularity, and lay MGO boards to level the floor.
• Top Frame Installation: Assemble the upper corner fittings with the top longitudinal beams, connect the top transverse beams, use a level to adjust the perpendicularity of the columns, and reinforce the top intersections.
• System Integration: Install drainage channels and downspouts, attach sealing strips, and then assemble wall panels and doors and windows (which need to be supported by wall panels on both sides), fix the ceiling, and lay roof insulation materials (such as glass wool). Finally, handle the details at the four corners of the house. This method emphasizes detachability and modularity, making it suitable for temporary buildings or mobile scenarios.

4. Prefabricated Panel Production Method This method combines traditional craftsmanship with modern technology, using cement and steel bars as core materials. The process involves nailing a hollow wooden mold, placing a steel bar framework inside, and pouring cement. After drying, the wooden mold is knocked off to form a prefabricated panel. These panels are mostly used for structures such as floor slabs and walls. The advantages include low cost and mature technology, but attention must be paid to the curing period and transportation protection to avoid cracking or deformation.
