It consists of an upper prefabricated ALC board and a lower on-site cast concrete layer. The ALC board is used in the prefabricated layer because of its light weight, thermal insulation, sound insulation and fire resistance. Steel bars can be embedded inside to enhance the structural strength. The composite floor is tightly combined with the upper and lower layers, which significantly improves the integrity and bearing capacity, and adapts to the requirements of large-span and high-load buildings. At the same time, it has good energy-saving and environmental protection performance, which is conducive to the design and implementation of energy-saving buildings. In addition, the lightweight characteristics of the ALC board make the construction convenient and efficient, which is in line with the development trend of building industrialization. After special processing, it has excellent durability and freeze-thaw resistance, and is suitable for building structures in various climatic environments.

The autoclaved lightweight aerated concrete composite floor described in the utility model makes the load-bearing and shock-absorbing capacity of the entire floor more excellent by adding anchoring steel bars and protective plates inside the floor, and at the same time improves the thermal insulation and anti-freezing ability of the building, by inserting the connecting seat of the first concrete slab into the second concrete slab In the large opening, it is convenient to quickly assemble and fix according to the on-site conditions when in use. Compared with traditional panels, the floor slab has more diverse structures and is more convenient, bringing better prospects for use. "When in use, the anchoring steel bars and protective plates added inside the floor slab make the load-bearing and shock-absorbing capacity of the entire floor slab more excellent, and at the same time improve the thermal insulation and frost resistance of the building.

[0016] 1. Through the setting of the connection assembly, the first connection block and the second connection block are used for splicing and fixing the adjacent floor slabs, and the elastic sealing strip is used to provide a good sealing effect to prevent moisture and air leakage, while effectively reducing the impact of temperature changes and vibrations on the floor slab connection, ensuring the tightness and durability of the floor slab connection;

[0017] 2. Through the setting of the floor structure, when in use, the crack resistance and flatness of the main plate are improved through the anti-cracking steel wire mesh and leveling mortar layer of the foundation component to ensure the quality and durability of the floor surface. The waterproof and breathable membrane of the protective support component provides waterproof and moisture-proof while allowing moisture to pass through. The first steel grid enhances the mechanical properties of the floor to ensure structural stability. The fireproof layer and isolation layer of the fireproof isolation component work together to effectively block the spread of fire and improve the fireproof performance of the floor. The thermal insulation layer, thermal insulation layer and connecting layer of the thermal insulation component cooperate with each other to reduce heat transfer and improve the thermal insulation performance of the floor. The second steel grid of the bottom component provides bottom support, and the connector ensures effective connection with the lower structure.
