1. Full Construction Process of Prefabricated Assembled Residential Buildings
These videos primarily feature real-life footage, comprehensively presenting the construction process from an empty lot to the finished product. Key steps include:

• Chassis Frame Construction: A stable supporting structure is formed using steel components or concrete foundations to ensure overall earthquake resistance and load-bearing capacity.
• Floor Joist Installation: Standardized wooden or light steel joists are used, quickly assembled and fixed with bolts.
• Wall Module Installation: Prefabricated wall panels include insulation layers and pre-installed piping, connected to the chassis using clips or bolts.
• Roof Truss Lifting: A crane precisely positions the prefabricated trusses to form a stable triangular structure.
  These videos emphasize the regularity of the construction rhythm, such as completing specific module installations each day, ultimately presenting structural aesthetics and functional integrity.

2. Prefabricated Component Construction Animations
These animations provide a detailed breakdown of component installation steps, suitable for technical training and standard demonstrations:

• Surveying and Layout: A laser positioning instrument is used to determine the installation axis of components, with errors controlled to the millimeter level.
• Rebar Position Verification: A rebar scanner is used to detect the positions of reserved rebars, ensuring alignment with component sleeves.
• Prefabricated Wall Panel Lifting: A balance beam hoist is used to keep the wall panels level, avoiding collisions with installed structures.
• Diagonal Bracing Fixation: Adjustable diagonal braces temporarily fix the wall panels, adjusting verticality before permanent connection.
• Sleeve Grouting: High-strength grout is used to fill the gaps between rebars and sleeves, forming an overall load-bearing system.
  The animations clearly show hidden engineering details, such as the flow path of the grout and methods for detecting compactness.

3. Prefabricated Beam Construction Animations
These specialized tutorials focus on the installation technology of large-span beams:

• Support Frame Construction: Disk-lock scaffolding or independent steel supports are used, with spacing and load-bearing capacity determined through calculations.
• Lifting Point Setting: Lifting points are designed based on the center of gravity distribution of the beam to avoid local stress concentrations that could cause cracking.
• Elevation Re-measurement: A level is used to repeatedly check the beam bottom elevation, ensuring alignment with adjacent components.
• Temporary Fixation: The beam is connected to the support structure using bolts or welding, with the supports removed after the concrete reaches strength.
  The animations simulate construction risks under different working conditions, such as controlling lifting stability under wind influence.

4. Prefabricated Concrete Module Lifting
These real-life videos record the core process of industrialized house construction:

• Module Design: The house is divided into concrete boxes with doors and windows, with individual weights reaching tens of tons.
• Lifting and Alignment: A crawler crane is used to lift the modules via steel cables and balance beams, achieving millimeter-level alignment through laser guidance.
• Node Connection: Wet connections (cast-in-place concrete) or dry connections (high-strength bolts) are used to form an overall structure.
• Construction Period Advantages: Modular construction can reduce on-site construction time by more than 50% and decrease the use of formwork and scaffolding.
