[0002] Autoclaved lightweight aerated concrete partition panels, or ALC for short, are available in products such as exterior wall panels, interior wall panels, floor panels, and roof panels, and are suitable for prefabricated structures. For example, Chinese invention patent application publication number CN 115787883 A discloses an energy-saving prefabricated building and its assembly method. The panels include ALC wall panels with a first locating groove installed on one side and a locating protrusion installed on the other side, which engages the first locating groove. The panels also have second locating grooves at both ends, and steel frame locating blocks are rotatably hinged within the second locating grooves via connecting shafts. The steel frame locating blocks have first and second locating holes at their ends, respectively.

The end of the second transverse section is connected to a second U-shaped section extending upward, the second U-shaped section is close to the lower side of the bottom ALC plate, the top plate of the second U-shaped section is inclined downward, and a third sealant is applied between the second U-shaped section and the plate.

[0022] With such a structure, the side of the first channel steel is convenient for installing the second flashing edge, and the drainage effect of the lower end edge of the bottom ALC plate is better.

[0023] As a further improvement of the present invention, a waterstop is provided in the joints between the ALC panels.

[0024] With such a structure, the waterstop helps to ensure the waterproofness of the joints.

[0025] The utility model is conducive to the assembled installation of the ALC exterior wall panels and is conducive to the vertical splicing of the ALC exterior wall panels, making the splicing more stable. BRIEF DESCRIPTION OF THE DRAWINGS
