How to Construct a Prefabricated Panel House

There are three main methods for constructing prefabricated panel houses: modular construction, general prefabricated assembly housing construction, and integrated modular building construction, as detailed below:

Modular Construction Method

This method involves assembling specially designed prefabricated panels without the need for steel bars and cement. First, the overall framework of the house is constructed using prefabricated panels, with the gaps between each panel filled with foam adhesive. Openings are reserved on the sides for natural lighting and entry. Thick prefabricated panels are joined to form seamless walls with good load-bearing capacity. When constructing the roof, a circular skylight tray is supported in the middle, fixed with crossbeams, and covered with thick wooden planks on top. The exterior walls are first wrapped with a waterproof foam layer, then covered with patterned waterproof tarpaulins, and secured with nails along the edges. The top of the house is equipped with transparent glass for natural lighting, and the interior crossbeams are filled with foam panels and then nailed with an additional layer of wooden planks. This construction method is relatively simple to operate, requiring lower construction skills and equipment, and is suitable for scenarios with lower building requirements and limited budgets, such as temporary housing and simple warehouses.

General Prefabricated Assembly Housing Construction

Starting from an empty lot, workers first construct the house's chassis framework on a pre-poured cement foundation, laying floor joists and locking each joint with metal connectors to ensure platform stability, then covering it with large wooden panels. After the foundation platform is completed, the prefabricated wall modules are moved onto the platform, erected, aligned, and fixed to the baseboard with nail guns. After the exterior wall framework is enclosed, internal fine division is carried out, building partition wall skeletons while laying the second-floor floor beams. Finally, roof construction is undertaken, with huge triangular trusses transported into position. Ground and roof workers cooperate to slowly lift and precisely place them on the top crossbeams of the walls. This method combines the advantages of prefabrication and on-site construction, ensuring certain building quality and stability, and is suitable for general residential construction.

Integrated Modular Building Construction

The building is disassembled into independent modules, which are manufactured in a factory, including ceilings, floors, and water and electricity pipelines, all prefabricated, and then transported to the construction site for assembly, similar to building with blocks. This construction method is highly efficient, significantly shortening the construction period, and factory prefabrication ensures high building quality and precision, suitable for projects with high requirements for building quality and efficiency, such as commercial buildings and schools.
