Collection of Prefabricated House Hoisting Videos

Here are some recommended videos related to the hoisting of prefabricated houses, covering different construction stages and technical points:

1. 《The Entire Process of Prefabricated Wall Hoisting: Fine Operations from Formwork to Wall Panel Installation》 This video provides a detailed demonstration of the entire process of prefabricated wall hoisting, from formwork production in the factory to on-site hoisting and installation. Key contents include:

• Formwork Production and Demolding: Introduces the standardized production process of prefabricated walls in the factory, including concrete pouring, curing, and demolding techniques, emphasizing the importance of formwork accuracy for wall dimension control.
• Hoisting Preparation and Positioning: Before on-site hoisting, walls need to be numbered, connection components checked, and installation positions accurately ensured using laser positioning instruments to avoid later adjustments.
• Hoisting and Fixing: Special lifting devices are used to complete wall lifting, translation, and vertical positioning. After temporary fixing with diagonal braces, node grouting or bolt connections are carried out to ensure structural stability.

2. 《Prefabricated Exterior Wall Hoisting Construction Animation》 This video simulates the hoisting process of prefabricated exterior walls through 3D animation, highlighting the following technical details:

• Hoisting Sequence Planning: According to the characteristics of the building structure, exterior walls at corners or key nodes are installed first, followed by the gradual completion of the overall enclosure structure to reduce the accumulation of construction errors.
• Sealing and Waterproofing Treatment: Immediately after hoisting, wall panel joints need to be sealed using weather-resistant adhesives or special sealing strips to prevent rainwater leakage, while reserving drainage slopes.
• Connection with the Main Structure: Demonstrates the flexible connection method between the exterior wall and the main structure, such as using rubber pads or shock-absorbing bolts, to accommodate temperature deformation and seismic effects.

3. 《Hoisting Animation of Prefabricated Components in Prefabricated Concrete Structures》 Focuses on the general hoisting methods of prefabricated components in prefabricated concrete structures, covering:

• Component Classification and Lifting Point Design: Design special lifting devices according to the shape of components (such as beams, slabs, columns) to ensure uniform force during hoisting and avoid local damage.
• Selection of Hoisting Machinery: Choose tower cranes or truck cranes according to the weight and height of components, and calculate the lifting moment to ensure construction safety.
• Temporary Support System: After hoisting, adjustable support frames need to be set up to control the verticality of components, which can only be removed after the connection strength meets the design requirements.

4. 《Comprehensive Analysis of the Installation Process of Prefabricated Assembly Buildings: From Bay Windows to Balcony Hoisting》 Taking an actual project as an example, this video analyzes the hoisting techniques for complex components:

• Bay Window Hoisting: Due to their large volume and offset center of gravity, bay windows require dual-crane lifting or balance beams to distribute the load, while temporary ties are set up to prevent overturning.
• Balcony Hoisting: Balcony slabs need to have lifting rings pre-embedded. During hoisting, the elevation is adjusted using a level, and they are fixed to the main structure by welding pre-embedded parts.
• Comprehensive Process Coordination: Emphasizes the cooperation among various work types (such as hoisting, measurement, welding), and simulates the construction sequence through BIM models to reduce on-site conflicts.

Viewing Suggestions:

• Beginners can prioritize watching animated videos (such as , ) to quickly understand hoisting logic;
• Construction personnel should combine practical case videos (such as , ) to master detail handling and safety regulations.
