[0016] Combine the following Figure 1 to Figure 2 The technical solution of the utility model is further illustrated by specific embodiments.

[0017] like Figure 1 The heat-insulating autoclaved aerated concrete board shown comprises: an autoclaved aerated concrete board 1, a first steel mesh 11, a second steel mesh 12 and a heat-insulating support assembly 2, wherein the first steel mesh 11 and the second steel mesh 12 are arranged in parallel in the thickness direction of the autoclaved aerated concrete board 1, and the autoclaved aerated concrete board 1 is formed with cement, lime and silica sand as main raw materials through high temperature, high pressure and steam curing, and the structure of the autoclaved aerated concrete board 1 is reinforced by pre-embedding the first steel mesh 11 and the second steel mesh 12.

[0018] The thermal insulation support components 2 are distributed between the first steel mesh 11 and the second steel mesh 12 at intervals, and the first steel mesh 11 and the second steel mesh 12 are supported by the thermal insulation support components 2 to improve the bending and compression resistance. In this embodiment, the first steel mesh 11 and the second steel mesh 12 are respectively close to the two opposite sides of the autoclaved aerated concrete plate 1, and the thermal insulation support components 2 are distributed in a rectangular array between the first steel mesh 11 and the second steel mesh 12, and are evenly distributed, thereby improving the compression resistance of the two sides of the autoclaved aerated concrete plate 1.

[0019] like Figure 2 As shown, the thermal insulation support assembly 2 includes a first steel bar column 21, a second steel bar column 22, a thermal insulation positioning sleeve 23 and a sheath 25. The first steel bar column 21 is arranged on the back of the first steel bar mesh 11 and points to the second steel bar mesh 12. In this embodiment, the first steel bar column 21 is welded and fixed to the first steel bar mesh 11, and the structure is stable.

[0020] The second reinforcement column 22 is disposed on the back side of the second reinforcement mesh 12 and is concentric with the first reinforcement column 21. In the present embodiment, the second reinforcement column 22 is welded and fixed to the second reinforcement mesh 12 to prevent it from falling off.

[0021] The heat-insulating positioning sleeve 23 is arranged between the first reinforcement column 21 and the second reinforcement column 22. Positioning blind holes 24 corresponding to the first reinforcement column 21 and the second reinforcement column 22 are arranged at both ends of the heat-insulating positioning sleeve 23 to insert and position and support the first reinforcement column 21 and the second reinforcement column 22. In this embodiment, the heat-insulating positioning sleeve 23 is made of a hard plastic sleeve, which has a good compression resistance effect, and the plastic sleeve can reduce the heat transfer between the first reinforcement column 21 and the second reinforcement column 22.

[0024] like Figure 1 As shown, the autoclaved aerated concrete board 1 is provided with an insulation groove 13 extending in the length direction, and the insulation groove 13 reduces the deadweight of the autoclaved aerated concrete board 1, thereby improving the insulation effect. In this embodiment, the insulation groove 13 is partially penetrated by the insulation support assembly 2, thereby ensuring the structural strength of the autoclaved aerated concrete board 1 at the insulation groove 13 position.
