[0022] As shown in the drawings, Figures 1-4 A high-strength autoclaved aerated concrete block, comprising a block body 1, the right side of the block body 1 is integrally formed with a connecting groove mechanism 2, and the left side is integrally formed with a connecting block mechanism 3 matched with the connecting groove mechanism 2. The connecting block mechanism 3 comprises a connecting block body 301, the top of the connecting block body 301 is integrally formed with a boss 303, and the boss 303 is integrally formed with a dovetail block 302. A plurality of limiting protrusions 304 are integrally formed on the side wall of the connecting block body 301 on the side of the dovetail block 302. The connecting groove mechanism 2 comprises a mismatched table matched with the boss 303, a plurality of limiting grooves matched with the limiting protrusions 304 are formed on the outer side wall of the mismatched table, and a dovetail groove matched with the dovetail block 302 is formed on the upper end surface of the connecting groove mechanism 2.

[0023] Specifically, the design of the dovetail groove and the dovetail block 302 enhances the mechanical engagement between the blocks, thereby improving the integrity, shear capacity and stability of the structure. The boss 303 and the mismatched table have a "mortise and tenon effect", which limits the relative sliding between the blocks and disperses the horizontal shear force. The limiting protrusions 304 and the limiting grooves cooperate with each other to accurately determine the position of the blocks, ensuring that each block can be installed according to the design requirements and avoiding positional deviation; in addition, when subjected to external forces such as earthquakes and winds, the movement of the blocks can be effectively limited, reducing the risk of cracks, deformation or even collapse of the wall body, improving the overall stability and seismic performance of the wall body; construction personnel can quickly find the installation position of the blocks according to the limiting protrusions 304 and the limiting grooves, without the need for repeated measurement and adjustment, thereby saving construction time and improving construction efficiency, while also reducing the dependence on the technical level of construction personnel, even if the workers have relatively insufficient experience, they can also relatively smoothly complete the installation work of the blocks.

[0024] The block body 1 is a hollow structure with upper and lower openings, which significantly reduces the weight of the block itself, facilitates transportation and construction, and also reduces the overall weight of the building structure, thereby reducing the pressure on the foundation. Secondly, the hollow structure forms an air layer, and the low thermal conductivity of air can effectively prevent heat transfer, reduce heat exchange between the inside and outside of the building, improve the thermal insulation performance of the building, reduce energy consumption, and achieve the purpose of energy saving. Thirdly, the hollow structure can block and absorb sound transmission to some extent, weaken sound propagation, and improve the sound insulation effect of the wall, creating a quiet environment indoors. Finally, the hollow structure reduces the weight of the building, which can reduce the effect of seismic force on the building during an earthquake, making the building more resistant to earthquakes and improving the safety of the structure.

[0025] The hollow structure is divided into several weight-reducing holes 4 by an integrally formed cross-shaped beam. According to actual needs, the weight-reducing holes 4 can be filled with thermal insulation materials to further reduce the thermal conductivity of the block, reduce heat transfer through the block, improve the thermal insulation effect of the building, and reduce energy consumption. At the same time, it can absorb and block sound, reduce sound propagation in the block, improve the sound insulation effect of the wall, and create a quiet environment indoors.

[0026] A plurality of steel bar insertion holes 8 are symmetrically provided on the upper end face of the block body 1. The steel bars 9 have high tensile strength and can withstand tension and shear force after being inserted into the steel bar insertion holes 8, thereby making up for the insufficient performance of the block in these aspects and improving the shear and bending strength of the wall, so that the wall can withstand greater loads, expand the application range of the block wall, and be especially suitable for building parts with large loads or high structural strength requirements. In addition, by inserting steel bars 9 into steel bar insertion holes 8 and pouring concrete, a reliable connection is formed between the blocks, connecting each block into a whole, enhancing the integrity and cooperative working capacity of the wall, and when subjected to external force, the wall can better bear the force together, improving the stability and seismic performance of the structure.

[0027] The steel bar insertion hole 8 includes a groove 801, and an insertion hole 804 is provided at the center of the groove 801. The groove 801 has a funnel structure, which does not interfere with the smooth connection of the block and facilitates the pouring of concrete, structural glue and other materials, thereby firmly bonding the steel bars 9 and the hole wall. The inner side wall of the insertion hole 804 is symmetrically provided with a sliding groove 802 vertically protruding and slidingly connected with the steel bars 9, which facilitates precise positioning and insertion of the steel bars 9. A plurality of filler grooves 803 are equidistantly provided on the inner side wall of the insertion hole 804 between the sliding grooves 802, which facilitates the pouring of concrete, structural glue and other materials.

[0028] The upper end face of the block body 1 is provided with a clamping groove, and the lower end face of the block body 1 is provided with a protrusion matched with the clamping groove, the clamping groove can provide accurate positioning in the up-down direction, ensure that each block can be accurately aligned with the adjacent blocks in the up-down direction when being built, which helps to ensure the perpendicularity and flatness of the wall, makes the appearance of the wall more neat and beautiful, and also provides a good basis for subsequent construction operations, such as plastering and tiling; meanwhile, the clamping groove and the corresponding protrusion cooperate with each other, so that the connection between the blocks is more compact and firm, and when subjected to external forces, such as earthquakes and wind, this connection mode can effectively limit the relative movement of the blocks, enhance the integrity and seismic performance of the wall, and reduce the risk of cracks, deformation or even collapse of the wall.
