[0035] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0036] like Figures 1 to 17 As shown, the utility model is a filled autoclaved aerated concrete Class A fireproof board, comprising an autoclaved aerated board 1 and a steel cage assembly embedded in the autoclaved aerated board 1, as shown in FIG. Figure 2 、 3As shown, the steel cage assembly is evenly embedded in the autoclaved aerated board 1 so that all six sides of the steel cage assembly are wrapped by the autoclaved aerated board 1 .

[0037] like Figure 1 As shown, the two long sides of the autoclaved aerated board 1 are respectively provided with a positioning groove 11 and a positioning protrusion 12. The positioning groove 11 and the positioning protrusion 12 both extend along the length direction of the long side and have the same length as the long side. The positioning groove 11 and the positioning protrusion 12 are both located in the middle of the thickness direction of the autoclaved aerated board 1, so that when two fireproof boards are butt-jointed, the positioning groove 11 of the long side is inserted into the positioning protrusion 12 of the other fireproof board to prevent the two from being misaligned.

[0038] The steel cage assembly includes two side-by-side steel meshes 2 and an insulation board 6 located between the two steel meshes 2. The steel mesh 2 is a rectangular mesh structure formed by connecting horizontal steel bars and vertical steel bars. The insulation board 6 is located between the two steel meshes 2 and is equidistant from the steel meshes 2 on both sides. The insulation board 6 is made of foam glass insulation board. The insulation board and the autoclaved aerated board are tightly fused and not easily separated, with high connection strength and light weight.

[0039] In order to fix the distance between the two steel meshes 2, multiple steel mesh connectors 3 are connected to the edges of the two steel meshes 2. In this embodiment, the upper and lower edges of the steel meshes 2 are each connected to multiple steel mesh connectors 3, and the steel mesh connectors 3 are evenly distributed on the upper and lower edges.

[0040] like Figure 8-10 As shown, the steel mesh connector 3 is a plastic part, which includes a connecting bar 31 and an outer clamping plate 32 fixed at both ends of the connecting bar 31. The length direction of the connecting bar 31 is consistent with the thickness direction of the autoclaved aerated board 1, so the two ends of the connecting bar 31 are respectively connected to two steel meshes 2.

[0041] The outer clamping plate 32 is located on the side of the connecting strip 31 close to the steel mesh 2, and the steel mesh is located between the two outer clamping plates 32. The inner side of the outer clamping plate 32 is provided with a clamping groove that fits with the outer side of the steel mesh 2. The clamping groove is an arc-shaped groove and fits with the outer cylindrical surface of the transverse steel bars of the steel mesh 2. When the steel mesh connector 3 is installed, the two steel meshes and the two outer clamping plates 32 are deformed, so that the transverse steel bars of the steel mesh enter the clamping groove.

[0042] To prevent the transverse reinforcement from falling out of the slot, an elastic piece 33 is fixed to the connecting strip 31 and fits on the inner side of the steel mesh 2. The elastic piece 33 is a U-shaped spring piece with one end fixed to the connecting strip 31. The transverse reinforcement is clamped between the other end of the U-shaped spring piece and the slot, thereby preventing it from falling out.

[0043] The middle of the connecting strip 31 is fixed with an intermediate positioning block 34, and the positioning hole 35 is provided on the intermediate positioning block 34. The positioning rod can be inserted into the positioning hole 35 of the steel mesh connector 3 to achieve its positioning and prevent the entire steel cage assembly from moving.

[0044] The positioning hole 35 in this embodiment passes through the side of the middle positioning block 34. Figure 9 As shown, that is, the top view of the positioning hole 35 is U-shaped, so that the positioning rod can be a hook-shaped structure, which hooks the middle part of the connecting strip 31 from the side of the positioning hole 35. While achieving positioning, the steel mesh connector 3 can be lifted, thereby achieving the lifting of the entire steel cage assembly, so that the steel cage assembly can be maintained at a suitable height position in the mold box.

[0045] like Figure 12 As shown, in order to maintain an appropriate spacing between the insulation board and the steel mesh, the steel cage assembly further includes a plurality of insulation board positioning mechanisms 4. The insulation board positioning mechanisms 4 include a screw 41 that passes through the insulation board 6 and two nuts 43 connected to the screw 41. The end of the screw 41 is provided with a slot that is clamped on the steel mesh 2. The slot is a countersunk hole provided at the end of the screw 41. The bottom spacing of the two countersunk holes is equal to the inner spacing of the two steel meshes 2. Therefore, when the two steel meshes are fixed, the screw 41 is also fixed, thereby playing a role in fixing and tying the two steel meshes.

[0046] The insulation board 6 is clamped between two nuts 43 , and a positioning gasket 42 is installed between the nuts 43 and the insulation board 6 , thereby achieving the fixation of the insulation board 6 .

[0047] like Figure 11 As shown, the steel cage assembly also includes multiple tensioning mechanisms 5, each comprising a sleeve 52 that passes through the insulation board 6 and the two steel meshes 2. A tensioning plate 51 is fixedly connected to one end of the sleeve 52, and a bolt 54 is threadedly connected to the other end of the sleeve 52. The two steel meshes 2 are clamped between the tensioning plate 51 and the bolt 54. A tensioning gasket 53 is installed between the bolt 54 and the steel meshes 2. The tensioning mechanism 5 also secures the fireproof panel during installation. During installation, the mounting plate can be installed in place of the tensioning gasket 53, and the mounting plate is then fixed to secure the fireproof panel.

[0048] A processing technology for filling autoclaved aerated concrete Class A fireproof board includes the following steps:

[0049] a. Fabrication of the steel cage assembly: Arrange the insulation board 6 and the two steel meshes 2 side by side, install the steel mesh connector 3 on the upper and lower edges of the steel mesh 2, and clamp the steel bars of the steel mesh 2 with the outer clamping plate 32 and the elastic sheet 33 at the end of the steel mesh connector 3 to achieve positioning between the two steel meshes 2. Pass the screw 41 through the insulation board 6, and make the clamping groove at the end of the screw 41 clamp on the steel mesh 2. Clamp the insulation board 6 with the two nuts on the screw 41 to achieve positioning between the steel mesh 2 and the insulation board 6. Pass the sleeve 52 through the insulation board 6 and the two steel meshes 2, so that the two steel meshes 2 are clamped between the tensioning plate 51 of the sleeve 52 and the bolt 54 to achieve clamping of the two steel meshes 2;

[0050] b. Casting and pre-curing: Place multiple steel cage assemblies side by side in the mold box 7, insert the positioning rods into the positioning holes 35 of the steel mesh connector 3 to achieve the positioning of the steel cage assemblies, pour the mixed slurry into the mold box 7 until the steel cage assemblies are completely covered, and let it stand for 2-8 hours to harden into an integral semi-finished product. Pull out the positioning rods after standing for 10-50 minutes;

[0051] c. Demolding: Open the movable side wall 8 on one side of the mold box 7, fit the movable support plate 9 to the side of the entire semi-finished product, rotate the movable support plate 9 and the mold box 7 together by 90 degrees, so that the movable support plate 9 is in a horizontal state, and transfer the entire semi-finished product to the movable support plate 9;

[0052] d. Cutting: The mobile support plate 9 drives the entire semi-finished product to move, and passes through a plurality of horizontal cutting wires 10 arranged vertically to cut the entire semi-finished product into a plurality of fireproof board semi-finished products arranged vertically. When the entire semi-finished product moves, it passes through the positioning groove scrapers 13 and positioning protrusion scrapers 15 on both sides, thereby scraping out positioning grooves 11 and positioning protrusions 12 on the two long sides of the fireproof board semi-finished product respectively;

[0053] e. Autoclave curing: The semi-finished fireproof board is sent into the autoclave for autoclave curing.
