[0025] Refer to Figures 1-4 , an embodiment provided by the present invention: a sound-insulating building plywood with high structural strength, including an enclosure board 3. Rubber pads 2 are fixedly connected to the outer sides of the upper and lower ends of the enclosure board 3. Composite boards 1 are fixedly connected to the opposite ends of the rubber pads 2. A plurality of through grooves 4 are formed in the inner wall of the enclosure board 3. A plurality of rubber strips 6 are fixedly connected between the upper and lower ends of the enclosure board 3 on both sides of the through grooves 4. The opposite ends of the rubber strips 6 are fixedly connected to the opposite ends of the composite board 1. Through the cooperation of the rubber pads 2 and the rubber strips 6, when the outside of the composite board 1 is subjected to pressure, it can be buffered through the elasticity of the rubber pads 2 and the rubber strips 6, thereby improving the structural strength of the plywood.

[0026] Specifically, sound insulation pads 5 are fixedly connected to the inner walls of the through grooves 4. Sound-touching surfaces 9 are formed on the four sides of the inner walls of the sound insulation pads 5. The shapes of the inner walls of the sound-touching surfaces 9 are all concave. When sound passes through the enclosure board 3, it is separated by a plurality of through grooves 4, thereby achieving the effect of weakening the sound impact. When the sound passes through the through grooves 4, it will be absorbed by the sound insulation pads 5. And a plurality of sound-touching surfaces 9 are formed on the inner walls of the sound insulation pads 5, thereby increasing the contact area between the sound and the sound insulation pads 5, thus improving the absorption of sound by the sound insulation pads 5 and realizing the sound insulation effect of the plywood. Moisture-proof layers 7 are fixedly connected to the inner walls of the composite boards 1. Fire-proof layers 8 are fixedly connected to the inner walls of the moisture-proof layers 7. The material used for the fire-proof layer 8 is flame-retardant foam, and the material used for the moisture-proof layer 7 is Portland cement. By filling the moisture-proof layer 7 and the fire-proof layer 8 in the inner layer of the composite board 1, the overall fire-proof and moisture-proof effects of the board are improved. The thicknesses of the composite board 1, the moisture-proof layer 7, and the fire-proof layer 8 are all 0.5 mm. The heights of the rubber pads 2 and the rubber strips 6 are both 0.64 mm. The height of the enclosure board 3 is 1.22 mm.

[0027] Working principle: First, by means of the moisture-proof layer 7 and the fire-proof layer 8 filled in the inner layer of the composite board 1, the overall fire-proof and moisture-proof effects of the board are improved. With the cooperation of the rubber pad 2 and the rubber strip 6, when the outside of the composite board 1 is subjected to pressure, it can be buffered through the elasticity of the rubber pad 2 and the rubber strip 6, thereby improving the structural strength of the plywood. When sound passes through the surrounding board 3, it is separated by a number of through grooves 4, thus achieving the effect of weakening the sound impact. When the sound passes through the through grooves 4, it will be absorbed by the sound insulation pad 5, and a plurality of sound contact surfaces 9 are provided on the inner wall of the sound insulation pad 5, thereby increasing the contact area between the sound and the sound insulation pad 5, and thus improving the absorption of the sound by the sound insulation pad 5 to achieve the sound insulation effect of the plywood.
