Prefabricated House Construction Method Video

The construction methods of prefabricated houses can be understood through the detailed operations in different stages shown in the following videos:

1. A Prefabricated House with Main Structure Completed in 14 Days This video demonstrates the core process of the rapid construction of a prefabricated house. First, the construction team uses 5-ton foundation piles combined with footplates to fix the foundation, ensuring structural stability. During the main structure construction phase, prefabricated components are quickly connected through mortise-and-tenon joints. For example, the connection between beams does not require complex welding; precise splicing is sufficient. The stair installation adopts a modular design, which is directly positioned using lifting equipment, followed by the laying of 5-centimeter-thick prefabricated floor slabs. Finally, grouting is carried out on all component gaps to enhance the overall structural integrity and improve waterproof performance. The entire process emphasizes standardization and efficiency, with the main frame completed in just 14 days.

2. A Comprehensive Analysis of the Installation Process of Prefabricated Assembly Buildings This video focuses on the precise installation of prefabricated components. The construction steps include:

• Layout and Positioning: Using a laser level to determine the building axis, ensuring the installation accuracy of prefabricated components;
• Rebar Tying: Wall and column rebars are connected mechanically or by welding, while floor slab bottom rebars are tied according to the designed spacing to form a load-bearing framework;
• Utility Pre-embedding: Reserving pipeline channels before concrete pouring to avoid structural damage from later slotting;
• Concrete Pouring: Adopting a layered vibration process to ensure a tight bond between the composite floor slab and prefabricated components. In addition, the video also demonstrates the installation techniques for prefabricated bay windows and balconies, emphasizing balance control and temporary support settings during component lifting.

3. Animation of Prefabricated Beam Construction This animation analyzes the key technologies of prefabricated beam construction in a three-dimensional format:

• Elevation Control: Marking the beam placement length control line on the prefabricated column, with an error margin controlled within ±2 millimeters;
• Lifting Process: Using a lifting beam spreader to distribute the load, preventing local deformation of the prefabricated beam;
• Support System: The support framework for the composite floor slab needs to be erected in advance to ensure the stability of the beam after positioning;
• Accuracy Re-measurement: Re-measuring the beam elevation with a total station, with a strict allowable error of within 5 millimeters to ensure the flatness of subsequent floor slab installation.

The above video content covers the entire process of prefabricated house construction, from foundation construction to component installation, including both efficiency optimization for overall construction and precision control at key nodes, providing visual references for practical engineering projects.
