How to Build a Prefabricated Panel House

There are three main methods for constructing prefabricated panel houses: modular assembly, prefabricated component assembly, and custom prefabricated panel combination. Details are as follows:

Modular Assembly Method:
This approach divides the house into independent standard modules, such as bedrooms, kitchens, bathrooms, and corridors. Each module undergoes steel structure welding, wall installation, pre-embedding of water and electrical pipelines, and door and window installation in a factory, resulting in a fully furnished and equipped room. After being transported by sea to the construction site, the modules are connected using cranes, secured with interface locking devices, and the water and electrical lines are linked up. This method significantly shortens the on-site construction period, reduces the impact of weather on the schedule, and ensures consistent building quality through modular production. It is suitable for standardized residential or temporary building projects.

Prefabricated Component Assembly Method:
This method uses prefabricated components as the main framework. During foundation construction, the site is first leveled and a concrete垫层 (pad layer) is poured. Anchor plates are installed to secure foundation piles, and then beams are quickly connected using mortise-and-tenon joints to form the main framework. Components such as stairs are installed using lifting methods, and after floor slab installation, the gaps between components are grouted to enhance structural stability. Finally, soil is backfilled to complete the framework enclosure. This method combines traditional construction techniques with prefabrication, retaining the flexibility of on-site adjustments while improving construction efficiency through prefabricated components. It is suitable for scenarios with complex terrain or partial customization requirements.

Custom Prefabricated Panel Combination Method:
This method uses customized prefabricated panels to assemble the house framework. The gaps between panels are filled with foam adhesive for sealing and moisture resistance, and openings for windows and entrance doors are reserved. The roof is fixed to the beams using circular skylight trays and covered with thick wooden planks to form a load-bearing layer. The exterior walls are wrapped with a waterproof foam layer and then fitted with a waterproof tarp. Transparent glass is used on the roof to enhance natural lighting, and foam boards are filled between interior beams and covered with wooden planks to improve thermal insulation. This method emphasizes lightweight and functional design, with material selection balancing cost and durability, making it suitable for temporary housing or low-budget projects.
