How to Install Prefabricated House Panels
The installation of prefabricated house panels varies depending on the type, mainly including prefabricated wall panels, prefabricated composite panels, etc. Here are the specific installation processes:
Installation Process for Prefabricated Wall Panels:
First, conduct positioning by using lifting measurement and setting out to release the positioning lines for the exterior wall panels, ensuring accurate installation positions. Simultaneously, correct any skewed rebars, using a dedicated rebar positioning plate to check the positioning and perpendicularity of the reserved rebars, avoiding subsequent connection issues. After placing adjusting shims, use a level to check the elevation, ensuring the wall panel's levelness meets design requirements. After positioning, install a temporary support system that is stable and adjustable to handle dynamic loads during construction. Subsequently, adjust the wall panel by fine-tuning the supports and shims to ensure the wall panel's perpendicularity, flatness, and elevation errors are within allowable limits. Finally, pour concrete to connect the wall panel with the main structure as a whole, ensuring the pouring process is vibrated densely to avoid defects such as honeycombing and pitting.
Installation Process for Prefabricated Composite Panels:
Before lifting, select appropriate lifting equipment, typically using a lifting steel beam to ensure that the lifting points bear force simultaneously, keeping the component stable and avoiding cracks or distortions in the composite panel due to uneven force. When the tower crane slowly lifts the prefabricated panel, control the lifting speed to avoid rapid swinging causing collisions. When lifted to about 500mm above the installation position, pause the lifting, and have construction personnel steady the composite panel and slowly lower it to the installation position. After positioning, check the fit between the composite panel and the supports (such as beams and walls) to ensure there are no gaps or misalignments. Subsequently, conduct temporary fixation, typically using welding or bolt connections, to prevent the composite panel from shifting during subsequent construction. Finally, perform rebar tying and concrete pouring to connect the composite panel with the supports as a whole, forming a continuous structural load-bearing system.
Installation Instructions for Other Types of Prefabricated Panels:
For prefabricated floor panels in prefabricated steel-concrete frame structures, installation requires close coordination with steel beams, but the specific process is not detailed, generally involving positioning, support, and connection steps. In the installation of prefabricated concrete floor panels, a typical thickness of 120mm floor panel has 8 main rebars, and when marking, note that the total length of the floor panel should be reduced by 2cm, but the full installation process is not detailed, and actual construction should be carried out in combination with design drawings and specification requirements.
