The ALC wall panel is arranged between a floor panel and a bottom panel and installed as a partition panel. Fixed bolts are pre-embedded on both the floor panel and the bottom panel. The fixed lap joint is an L-shaped structure. One side of the fixed lap joint is fixed to the floor panel or the bottom panel by a fixed bolt, and the other side of the fixed lap joint abuts against the outside of the top or bottom end of the ALC wall panel. One end of the hook bolt is fixed to the inside of the ALC wall panel by a nut. The hook portion of the hook bolt passes through the top or bottom end of the ALC wall panel and is hooked on the fixed lap joint.

[0006] Preferably, a further technical solution of the present invention is: The fixed overlap part includes a flat steel adapter and a galvanized angle steel. The flat steel adapter abuts the bottom side of the floor slab or the top side of the base plate. One side of the galvanized angle steel overlaps the outside of the flat steel adapter. The other side of the galvanized angle steel is used to abut the top or bottom end of the outside of the ALC wall panel. The hook of the hook head bolt abuts the outside of the other side of the galvanized angle steel.

[0007] The outer side of the flat steel connector is welded and fixed to one end of the galvanized angle steel.

[0009] The present invention is to solve the above problems, and its specific solution 2 is: The integrated building ALC wall construction method includes the following steps: Step 1: Pre-integrate the construction floor slab, building base slab and corresponding insulation layer. During construction, pre-embed fixing bolts at the positions of the floor slab and base slab corresponding to the ALC wall panels. Use expansion bolts as the fixing bolts. Pre-embed the threaded sleeves of the expansion bolts in the floor slab and base slab, and manufacture the ALC wall panels according to the design drawings. Step 2: Pre-weld the flat steel adapter and one side of the galvanized angle steel to form an integral L-shaped structure. Open bolt holes at the welding position, place the flat steel adapter and one side of the galvanized angle steel on the floor or base plate, and screw the expansion bolt's screw through the bolt hole into the expansion bolt's threaded sleeve to fix the flat steel adapter and one side of the galvanized angle steel. The other side of the galvanized angle steel is bent toward the middle perpendicular to the floor and base plate. Step 3: Install the ALC wall panel between the floor slab and the base plate from the interior, so that the top and bottom ends of the ALC wall panel are in contact with the other side of the galvanized angle steel; Step 4: Insert the hook bolts into the top and bottom of the ALC wall panel outdoors, so that the hooks of the hook bolts overlap the other side of the galvanized angle steel, and weld the overlapped positions to fix them. Use nuts to fix the hook bolts that pass through the inside of the ALC wall panel. Step 5: Squeeze special adhesive for panels into the gaps between the floor or bottom panel and the flat steel adapter or ALC wall panel.

[0010] Compared with the prior art, the present invention adopting the above technical solution has the following beneficial effects: The integrated building ALC wall connection device and construction method of the present invention are provided with a flat steel adapter to move the galvanized angle steel outward to avoid the insulation layer, thereby avoiding damage to the insulation layer structure when installing the ALC wall panel.
