Prefabricated Wall Assembly Images

Currently, direct images of prefabricated wall assembly are not available, but understanding can be enhanced through descriptions of project cases and component types. For specific acquisition methods, refer to professional atlases or project materials.

Prefabricated wall assembly is a core technology in prefabricated construction, focusing on the standardized production of wall components (such as prefabricated wall panels and composite beams) in factories, followed by precise assembly on-site. The following explains its technical characteristics and image acquisition methods through typical project cases and component types:

I. Types of Prefabricated Walls in Typical Projects

1. "Sandwich" Insulated Prefabricated Walls
   Taking the Qinxing Jiayuan project as an example, this wall adopts a composite structure of outer leaf panel (decorative layer) + insulation layer + inner leaf panel (structural layer), achieving millimeter-level precision assembly through BIM technology. Such walls complete the integrated pouring of the insulation and structural layers in the factory, requiring only lifting and positioning on-site, significantly reducing wet work and construction errors.

2. Prefabricated Shear Wall System
   The Shenzhen Prison Affordable Housing project adopts this system, involving the installation of prefabricated exterior wall panels and composite beams. The prefabricated exterior wall panels typically include embedded parts for door and window openings, while the composite beams have reserved reinforcement for connection with the floor slab. On-site, structural integrity is achieved through sleeve grouting or welding. The assembly of such walls strictly follows the construction sequence of "walls first, then beams" to ensure component positioning accuracy.

3. Lightweight Panel Enclosure Walls
   For example, ALC panels (autoclaved aerated concrete panels), typically 100-300mm thick, are lightweight and can be quickly assembled using bolts or special connectors. Such walls are mostly used for non-load-bearing enclosure structures, suitable for interior partitions or exterior walls in residential buildings, schools, etc.

II. Key Steps in the Prefabricated Assembly Construction Process

1. Component Production: Components are molded or extruded in factories, completing reinforcement tying, embedded part installation, and surface treatment.
2. Transportation and Stacking: Special racks are used to secure components during transportation to prevent deformation; on-site stacking requires setting up wooden pads to prevent cracking.
3. Lifting and Positioning: Vertical transportation is carried out using tower cranes or truck cranes, with laser positioning instruments or total stations controlling component verticality and levelness.
4. Connection and Fixing: Load-bearing components (such as shear walls) are connected using sleeve grouting, while non-load-bearing components (such as ALC panels) are fixed with bolts or adhesives.

III. Image Acquisition Methods

1. Prefabricated Construction Atlases: National standard atlases such as "Architectural Construction of Prefabricated Concrete Structures" (15G310-1/2) contain detailed node drawings and assembly diagrams of typical components.
2. Project Case Materials: Contact the construction units or design institutes of prefabricated construction demonstration projects (such as Qinxing Jiayuan and Shenzhen Prison Affordable Housing) to obtain construction process photos or 3D model screenshots.
3. Professional Databases: Search for keywords like "prefabricated wall assembly" on platforms such as the "National Architectural Standard Design Network" and "CNKI" to download relevant images from papers or technical reports.
