Construction Process of Prefabricated House Panels

The construction process of prefabricated house panels varies depending on the type of panel. Common types include prefabricated exterior wall cladding panels, prefabricated composite slabs, and prefabricated partition panels. The specific construction processes are as follows:

Construction Process of Prefabricated Exterior Wall Cladding Panels

1. Floor Surface Treatment and Elevation Verification: First, clean the floor surface and verify the relative elevation of the floor at the location where the prefabricated cladding panel will be installed. If the error exceeds 5mm, grinding or repair is required to ensure the floor flatness meets the requirements.
2. Positioning and Anti-Leakage Measures: Mark the positioning edge lines and control lines of the prefabricated cladding panel on the floor slab to clarify the installation position. Adhere anti-leakage adhesive strips at the joints with the cast-in-place structure to prevent concrete leakage during pouring.
3. Hoisting and Positioning: Use a tower crane to slowly lift the prefabricated cladding panel. When the bottom of the panel rises to 50cm above the ground, pause to check the lifting equipment and the panel's condition before continuing to lift. When the panel is 50cm above the working layer, pause again. Construction personnel hold the panel to control its descent direction and slowly lower it to a stable position.
4. Support Installation and Adjustment: Install upper and lower diagonal supports. The lower diagonal support is used to adjust the in-and-out position of the cladding panel for bottom positioning. After releasing the lifting equipment, the upper diagonal support precisely adjusts the wall verticality to ensure the installation accuracy of the cladding panel.
5. Installation of Subsequent Components: Install other prefabricated components in sequence to complete the overall structural assembly.

Construction Process of Prefabricated Composite Slabs

1. Foundation Treatment and Support Installation: Clean the installation area, determine the installation position of the prefabricated composite slab, and install dedicated supports to provide stable support for the composite slab.
2. Lifting Equipment Selection and Hoisting: Use a lifting steel beam as the lifting equipment to ensure that the lifting points bear the load simultaneously, allowing the component to be hoisted smoothly and avoiding cracks or distortions during hoisting.
3. Hoisting Operation: Use a tower crane to slowly lift the prefabricated composite slab and proceed with subsequent installation operations after completing the hoisting.

Construction Process of Prefabricated Partition Panels

1. Tool Preparation and Ground Beam Construction: Check whether the construction materials and tools are complete, and construction personnel complete technical disclosures. Conduct ground beam construction, including processes such as marking lines, reinforcing bar planting, formwork erection, grouting, full grouting, formwork removal, and curing.
2. Mold Making and Prefabricated Panel Production: Make a mold frame using galvanized square tubes according to the design dimensions and lay a film to prevent concrete adhesion. Place a steel reinforcement mesh inside the mold to enhance structural strength, pour concrete, and implant welded parts. Remove the mold after the concrete sets.
3. Prefabricated Panel Installation: Precisely align the embedded parts of the prefabricated wall panels with those of the ground beams, walls, and ceilings, and fix them by welding to ensure wall stability.
4. Stone Paving: Drill holes according to the planned positions, finely grind the stone surfaces and joints, and use the wet-laying construction method for paving to enhance the wall aesthetics.
