[0002] ALC is the abbreviation of autoclaved lightweight aerated concrete, which is a kind of high-performance autoclaved aerated concrete. ALC board is a porous concrete forming board made of fly ash or silica sand, cement, quicklime, gypsum and other raw materials, with aluminum powder as a foaming agent, and cured by high-pressure steam. ALC board is suitable for roofs, floors, interior partitions, exterior walls, etc. It is a new type of high-efficiency and energy-saving building material that is currently being promoted. It is also suitable for building industrialization and assembly construction. It has the properties of low density, high quality, high strength, durability, earthquake resistance, fire resistance, thermal insulation, sound insulation, moisture retention, and environmental protection.

[0003] The promotion and use of ALC wall panel construction will drive the construction industry from backward wet construction to advanced dry construction. Among them, the "construction method for preventing cracks in ALC wall panel splicing" disclosed in patent CN115341681A applies mortar to the side of the ALC wall panel, lays the joints with fiber mesh cloth, and uses anti-cracking mortar to level and compact. The top of the wall panel and the connection between the beam and slab are sealed with mortar: However, it still fails to systematically solve the installation and fixation of the top of the wall panel and the concrete structure beam and slab and the compaction of the mortar for filling the joints, resulting in poor stability and difficulty in ensuring the filling width during the installation of the ALC wall panel, affecting the quality of the project construction. Summary of the invention

[0004] In view of the deficiencies in the prior art, the object of the present invention is to provide an ALC wall panel top fixing device and an ALC wall panel fixing method, which can ensure the caulking width, quickly realize the on-site installation of the wall panel, and improve the construction efficiency.

[0005] The preferred embodiment adopted by the present invention is: A top fixing device for an ALC wall panel comprises a device body, which is placed between the ALC wall panel and the beam plate. The device body comprises an angle steel, a fixing seat and a hook bolt. The angle steel is arranged throughout the length of the wall panel installation position, and the angle steel is fixed at the lower edge of the beam plate; the fixing seat is pre-buried in the top of the ALC wall panel, and each fixing seat is threadedly connected to one end of a hook bolt respectively, and the other end of the hook bolt is fixedly connected to the angle steel.

[0007] Further, the preferred embodiment adopted by the present invention is: The center of the fixing seat is 60-80mm away from the top of the ALC wall panel.

[0008] The embedded depth of the fixing seat is 40mm from the ALC wall panel surface.

[0009] The present invention also relates to an ALC wall panel fixing method, the specific steps are as follows: S1. Layout the wall panels according to the architectural drawings and structural drawings. Determine the embedded position of the fixing seat on the ALC wall panels according to the layout position of the wall panels. Fix the embedded seat to the steel cage of the ALC wall panels before pouring the ALC wall panels. Block the end of the fixing seat with bolt holes. Then pour the ALC wall panels. After the ALC wall panels are manufactured, enter the construction site. S2. Before construction, clean the base layer according to the construction requirements, and then mark the ALC wall panel position line and elevation line; S3. A full-length angle steel is fixed on the beam plate at the installation position corresponding to the ALC wall panel; S4. Install a U-shaped card at the joint at the bottom of each ALC wall panel, and the U-shaped card is fixedly connected to one of the ALC wall panels; The top of S5 and ALC wall panels are fixed to the angle steel by hook bolts; S6, then composite the installation elevation, plane position and flatness; S7. Use waterproof mortar to seal the bottom and top gaps of ALC exterior wall panels.

[0010] This method reduces the drilling work at the construction site and the subsequent process of filling and repairing the holes, can achieve rapid installation, and reduces the risk of unstable construction quality. BRIEF DESCRIPTION OF THE DRAWINGS
