[0015] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0016] Example:

[0017] like Figure 1-Figure 2As shown, a foam concrete insulation board comprises at least one foam concrete board 1, a bracket 5 arranged in the foam concrete board 1, and flocculent glass wool 3 filled in the foam concrete board 1; the foam concrete board 1 comprises a top plate, a bottom plate and four side plates integrally arranged with the top plate and the bottom plate; after the bracket 5 is installed and the glass wool 3 is filled, the top plate and the bottom plate are integrally provided with side plates for sealing around them; the bracket 5 comprises at least one inclined support plate, and the two ends of each support plate are fixedly connected to the top plate and the bottom plate of the foam concrete board 1 by bolt rods 6 respectively; multiple support plates can be connected and extended in sequence in the horizontal or longitudinal direction; the bolt rods 6 are pre-buried in the inner side of the top plate and the bottom plate of the foam concrete board 1; the filled flocculent glass wool 3 and the glass wool 3 with high thermal resistance value can effectively delay the heat transfer of the foam concrete insulation board, increase the insulation effect of the insulation board, and at the same time, improve the sound insulation performance of the wall panel.

[0018] The bracket 5 is made of aluminum alloy; the foam concrete board 1 is made of fly ash; the foam concrete board 1 is a fly ash foam concrete board, and the fly ash foam concrete board 1 utilizes industrial solid waste fly ash to solve the problem of fly ash accumulation and environmental pollution. The addition of fly ash to replace part of the cement is beneficial to reduce the amount of cement and reduce costs; at the same time, for areas rich in coal resources, the fine ash collected in the flue gas generated after coal combustion is fly ash. A large amount of fly ash accumulation will cause waste of land resources and environmental pollution. This solution utilizes fly ash at a low cost and is green and environmentally friendly; the foam concrete boards 1 on both sides are fixedly connected by the aluminum alloy bracket 5, which improves the shear resistance of the foam concrete board 1.

[0019] When there are more than two support plates, all support plates are connected in sequence, that is, the head end of the rear support rod is connected to the end of the front support rod; the connection between the two support plates is fixedly connected to the foam concrete board 1 using the same bolt rod 6.

[0020] Bolt holes are correspondingly arranged at the connection points of the two support plates, and the bolt holes are connected to the bolt rods 6 .

[0021] The outer side of the foam concrete board 1 is coated with a waterproof decorative layer 4 , which not only makes the foam concrete board 1 beautiful in appearance, but also improves the durability of the foam concrete 1 .

[0022] When there are two foam concrete panels 1, the two foam concrete panels 1 are provided with tongue-and-groove joints 2 that match each other on opposite sides; that is, on the opposite sides, one foam concrete panel 1 is provided with a protruding tenon, and the other foam concrete panel 1 is provided with a mortise and tenon groove corresponding to the tenon.

[0023] When there are three foam concrete slabs 1, the three foam concrete slabs 1 are spliced in sequence horizontally or vertically; rabbet joints 2 are provided on the opposite sides of the two foam concrete slabs 1 at both ends, and rabbet joints 2 matching the rabbet joints 2 of the foam concrete slabs 1 on both sides are respectively provided on both sides of the foam concrete slab 1 in the middle. Through the connection of the rabbet joints, the connection between the foam concrete slabs is made safer and firmer, the integrity of the foam concrete slabs is increased, and the waterproof decorative layer can beautify and extend the service life of the insulation board.

[0024] Working principle: The heat in the building interior and the cold air outside will encounter the lattice foam concrete slab 1. The tiny voids contained in the foam concrete slab 1 will reduce the heat transfer. The flocculent glass wool 3 filled in the voids between the two panels can also further play a role in reducing the heat transfer, strengthening the heat insulation effect of this kind of foam concrete insulation board and better maintaining the temperature; at the same time, the foam concrete slab 1 itself has good sound insulation performance. The flocculent glass wool 3 filled between the two panels can reduce the sound transmission and play a good sound insulation performance; the upper and lower foam concrete slabs are fixedly connected by aluminum alloy brackets, improving the shear resistance of the foam concrete slab 1. Through the connection of the rabbet joints 2, the connection between the foam concrete slabs 1 is made safer and firmer, increasing the integrity of the foam concrete slabs 1. The waterproof decorative layer 4 can beautify and extend the service life of the insulation board.

[0025] Compared with the traditional wall panels, this insulation board improves the heat insulation performance and sound insulation performance, and the fly ash used as the material is an industrial waste, which can reduce the cost of the wall panels.

[0026] Manufacturing process: Align the bolt rods 6 reserved in the two foam concrete slabs 1 with the bolt holes on the aluminum alloy bracket 5 and fix them with nuts; in the void formed by the two foam concrete slabs on both sides, blow the flocculent glass wool into the cavity with high-pressure air and fill it densely without leaving any voids; finally, apply a waterproof decorative layer on the outside of the foam concrete slab 1 to improve the durability of the wall panel, and then connect the assembled foam concrete slabs 1 through the rabbet joints 2.

[0027] The above is only used to illustrate the technical solution of the present invention and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention shall be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
