Prefabricated House Assembly Building Video
Videos related to prefabricated house assembly and construction showcase the entire process from foundation setup to overall completion, covering key aspects such as standard floor construction and detail handling. The following provides a detailed explanation through specific examples, focusing on three aspects: construction process, technical points, and typical procedures.
I. Foundation Setup and Main Frame Construction
Some videos document the complete construction process of prefabricated houses starting from an empty lot in real-time. Initially, workers operate on pre-cast concrete foundations, first unloading heavy timber to construct the house's chassis frame and lay floor joists, providing stable support for subsequent structures. Subsequently, large wooden panels are transported to the site and placed over the platform, forming the house's foundational platform. The installation of wall modules is a critical step, where workers place pre-fabricated wall modules onto the platform and erect them, ensuring tight connections between modules through precise positioning. During the internal fine division phase, workers perform operations such as slotting and wiring on the walls according to design requirements, reserving space for electrical and plumbing installations. For multi-story houses, the installation of second-floor floor beams is also necessary, secured with bolts or welding to ensure the stability of upper and lower structures.
II. Standard Floor Construction and Typical Procedure Analysis
Another category of videos focuses on standard floor construction procedures, such as the installation of pre-fabricated bay windows and balconies. Bay window installation requires pre-installed connectors on the main structure, with pre-fabricated bay window modules precisely positioned using lifting equipment and then secured with high-strength bolts or welding to ensure airtightness between the window and wall. Balcony installation involves pre-embedding steel components at the edge of the floor slab, with lifting equipment aided by guiding devices for positioning during installation, followed by waterproofing treatment and load testing after completion. These procedures reflect the characteristics of prefabricated construction: "standardized design, factory production, and assembly construction," shortening on-site construction time through modular combinations while reducing construction waste and noise pollution.
III. Roof Construction and Finalization Work
Roof construction marks the final stage of prefabricated house assembly. Videos commonly show workers using lightweight steel structures or pre-fabricated concrete roof panels to construct the roof frame, followed by laying waterproof membranes and insulation layers, and finally installing roof tiles or metal sheets. Finalization work includes window and door adjustments, exterior wall decoration, and interior finishing, such as installing pre-fabricated stairs, laying floors, and painting walls. Throughout the process, industrial production ensures component precision, with only simple assembly required on-site, significantly improving construction efficiency and quality control.
