Prefabricated Housing Assembly Videos
Prefabricated housing assembly-related videos are rich in content, covering the entire process from basic construction to detailed installation. The following provides a popular science analysis from three dimensions—construction process, lifting technology, and construction control—based on specific video cases:
I. Full Process of Workers Constructing Prefabricated Assembly-Type Residential Buildings
This type of video records the three-dimensional construction process of a house from an empty lot to completion from a first-person perspective. Foundation Construction Phase: Workers first install the house chassis frame on a pre-poured cement foundation, securing it with bolts for stability; then, they lay floor joists to form a support structure. Wall Installation Phase: Large wooden panels are transported to the platform to cover the chassis, forming a base platform; prefabricated wall modules are lifted to designated positions by cranes, and workers adjust their verticality using a level before fixing them to the chassis with metal connectors. Internal Fine Construction Phase: Partition wall skeletons are constructed using light steel joists, ensuring both strength and reduced weight; the laying of the second-floor floor beams must align precisely with the first-floor wall modules to ensure overall structural stability. Roof Construction Phase: Prefabricated triangular trusses are lifted to the top of the walls and connected to the walls with bolts, forming a complete load-bearing system. These videos visually demonstrate the characteristics of prefabricated buildings, such as "modular design and standardized installation", where each component is prefabricated in the factory and only needs to be assembled on-site, significantly shortening the construction period.
II. Full Process Analysis Videos of Prefabricated Assembly-Type Building Installation
This type of video focuses on the lifting technology of special components, taking bay windows and balconies as examples. Bay Window Lifting: Special lifting fixtures are used, and a balance beam ensures the component remains level; after being lifted to the designated position, workers adjust its position with a laser positioning instrument and then connect it to the wall with high-strength bolts, with the connection sealed with waterproof tape to prevent leakage. Balcony Lifting: Consideration must be given to load-bearing issues; prefabricated balconies have steel beams pre-embedded at the bottom, which are connected to the main structure by welding; during the lifting process, dual cranes must work in coordination to ensure the component descends smoothly. These videos emphasize the importance of lifting sequence, such as installing bay windows before balconies to avoid spatial conflicts; they also highlight safety measures, such as setting up warning lines and wearing safety harnesses.
III. Micro-Lecture Videos on Installation and Construction Control Points of Prefabricated Interior Walls in Assembly-Type Buildings
This type of video analyzes interior wall installation details from a technical specification perspective. Material Selection: Prefabricated interior walls use lightweight concrete or gypsum board, meeting fire protection requirements and facilitating transportation. Installation Process: Positioning lines must be snapped on the floor and ceiling to ensure wall verticality; wall modules are connected to the structure with U-shaped clips, with clip spacing conforming to design specifications (usually 600mm). Construction Control Points include: Joint Treatment: Special joint filler is used to fill wall joints, the surface is smoothed, and anti-crack tape is applied; Pipeline Pre-embedding: Pipeline slots are reserved during the factory prefabrication stage to avoid damaging the structure by on-site trenching; Quality Inspection: After installation, a 2m level is used to check wall flatness, with an error margin controlled within 3mm. These videos emphasize fine construction, ensuring building quality through standardized processes.
