[0001] The invention provides a portable installation device for an autoclaved aerated concrete slab and a use method thereof, belonging to the field of secondary structure wall construction. Background Art

[0002] Autoclaved aerated concrete wall panels (ALC partition walls) are a lightweight, porous, and environmentally friendly building material made primarily from cement, lime, and silica sand, with varying amounts of anti-corrosion-treated steel mesh added according to structural requirements. Through high-temperature, high-pressure, and steam-curing processes, the resulting porous, crystalline autoclaved aerated concrete panels possess a lower density than typical cementitious materials and offer unparalleled properties such as fire resistance, fire protection, sound insulation, thermal insulation, and heat preservation.

[0003] It's well known that autoclaved aerated concrete wall panels offer advantages over conventional masonry, such as ease of construction, energy conservation, environmental protection, and time and labor savings. However, conventional installation methods for autoclaved aerated concrete wall panels inevitably require significant manual labor for handling and assembly, leading to significant increases in labor costs when constructing large areas.

[0018] The two sets of clamping plates are suitable for clamping on the side of the concrete wall panel away from the working surface.

[0019] A method for using a portable installation device for autoclaved aerated concrete panels, characterized by comprising the following steps:

[0020] Step 1: Before installing the autoclaved aerated concrete wall panels, it is necessary to lay out the lines in advance to determine the position of the concrete wall panels and fix the U-shaped slots with steel nails. The position of the U-shaped slots must be determined in advance according to the width of the wall panels to ensure that they are set at the joints of the wall panels.

[0021] Step 2: When transporting the wall panels, the entire device needs to be tilted backward to reduce the height and increase stability to prevent collision with other indoor structures;

[0022] Step 3: During installation, the wall panel transport vehicle is parked on one side of the wall. After the concrete wall panel is flush with the U-shaped slot, the electric push rod is started to drive the longitudinal guide rod to push the concrete wall panel. After the first wall panel is pushed into place, the telescopic steel bottom plate is immediately retracted to make the second wall panel flush with the U-shaped slot, and this process is repeated.

[0023] Step 4. After the wall panels are installed, fold the front baffle of the base plate, raise the wooden wedges, pull out the steel base plate, and use a 2m ruler to check the flatness and verticality of the wall. Adjust the wooden wedges to ensure that the flatness and verticality of the wall panels meet the required position. Finally, fill the joints with plaster and smooth them. After the wall panels are fixed, fill the gaps at the upper and lower ends with special wall panel adhesive. The wooden wedges for positioning the joints should be removed after the adhesive hardens and filled with homogeneous adhesive.

[0024] In a further technical solution, in step 3, after the concrete wall panel is flush with the U-shaped slot, the connection between the side tie rod and the positioning plate is opened to loosen the clamping plate on the first connecting plate from the concrete wall panel;

[0027] The present invention facilitates the raising and lowering of concrete wall panels by arranging rollers on the first connecting plate, and realizes that when the first connecting plate is perpendicular to the ground, it can be clamped to a separate concrete wall panel by a clamping plate through a positioning piece. The side of the concrete wall panel is closed by a side tie rod.

[0028] The present invention ensures that a single set of longitudinal guide rods can continuously push concrete wall panels by setting a longitudinal conveyor chain, and the stepper motor in the wall panel transport vehicle stably transports the longitudinal conveyor chain. Through the above-mentioned construction method, the present invention significantly improves the transportation and installation efficiency of autoclaved aerated concrete wall panels, further speeds up the progress and reduces labor costs.
