[0015] The following is the specific embodiment of the utility model, and the technical scheme of the utility model is further described in combination with the drawings, but the utility model is not limited to these embodiments.

[0016] As Figures 1-3 The utility model discloses a high -strength light -duty floating bead fireproof heat insulation plate, including support shell 1, the heat insulation plate 2 of being placed in support shell 1, support shell 1 top is equipped with cover plate 3, and the both sides of cover plate 3 are positioned on support shell 1 by screw 4, and screw 4 is distributed on the both sides of support shell 1, and the limiting hole is seted up on cover plate 3, when installing, screw 4 is inserted into the limiting hole of cover plate 3, and screw 4 is connected with locking nut 5 on the screw thread, the heat insulation plate 2 includes floating bead plate 6, and the inside of floating bead plate 6 is equipped with light steel framework 7, the bottom of support shell 1 and the inside of cover plate 3 all are equipped with buffer pad 10.

[0017] As Figure 1As shown, the surface of the fly ash layer is impregnated with aluminosilicate aerogel with a thermal conductivity ≤0.025 W / (m·K), and an ultra-thin coating of 0.1-0.5 mm replaces the traditional rock wool layer, reducing the thickness and weight of the insulation layer; a lightweight steel frame 7 is embedded in the fly ash board 6, which solves the problem of low structural strength of traditional fly ash refractory insulation boards and improves the overall bending resistance; during transportation, the processed and cut insulation boards 2 are placed in the support shell 1, and then the cover plate 3 is put on the screw 4, and the cover plate is tightly pressed against the insulation board 2 by the locking nut 5. The buffer pad 10 can maintain the stability of the insulation board 2 during the journey and improve the protection of the insulation board 2.

[0019] like Figure 3 As shown, the lightweight steel frame 7 uses prefabricated wire mesh. Before laying the mixed cenosphere material on the template, a layer of wire mesh is laid on the template, and then the mixed cenosphere material is evenly laid on top. At the same time, another layer of wire mesh is laid after laying the cenosphere material. The two layers of wire mesh have a certain gap. Then, through high temperature and high pressure technology, and by controlling the pressure to achieve the uniformity of the material, the lightweight steel frame 7 and the cenosphere material are combined to improve the overall bending resistance and increase the strength of the fire-resistant insulation board. The mesh size of the wire mesh can be between 10 and 500. The appropriate mesh number is selected according to actual needs. The more mesh numbers, the stronger the bending resistance of the processed insulation board 2.
