Compared with cardboard structure products, hollow board has the advantages of moisture-proof and corrosion-resistant.
[0003] Existing hollow board structures are composed of two boards and a vertical frame, wherein the vertical frame is located between the two boards. However, this type of hollow board does not have a sound-absorbing structure, has a poor sound insulation effect, and has poor impact resistance. Utility Model Content

[0008] Preferably, sound holes are provided on the upper surface of the sound-absorbing blocks, and the sound-absorbing blocks are arranged in a matrix, and the directions of the sound holes are random.
[0009] Through the above technical solution, by setting the silencer block and the sound hole, during the transmission of sound waves, when the surface of the silencer block is released, diffuse reflection will occur, reducing the reflection intensity of the sound, thereby improving the noise reduction effect of the hollow board body.
[0010] Preferably, a connecting groove is provided on the left side surface of the hollow plate body, and a connecting strip is provided on the right side surface of the connecting groove.
[0011] Through the above technical solution, by providing the connection grooves and the connection strips, it is convenient for workers to assemble the hollow board body, which is easy to operate and quick to install.

[0014] Preferably, the first sound insulation layer is sound insulation cotton, and the second sound insulation layer is a sound absorbing board.
[0015] Through the above technical solution, the sound insulation cotton is mainly made of fiber or porous material, and contains a large number of tiny interconnected pores inside. When sound propagation encounters the sound insulation cotton, the sound waves will enter these pores and repeatedly refract, collide and consume energy therein, converting the sound energy into heat energy, thereby greatly reducing the penetration of the sound, achieving excellent sound absorption effect, and effectively isolating indoor and outdoor noise. The sound-absorbing panels can absorb sound efficiently. The sound-absorbing panels can effectively absorb noise and reduce the interference of noise to people.

[0016] Preferably, the reinforcing ribs are arranged in a triangle.
[0017] Through the above technical solution, the impact resistance of the hollow plate body can be improved by setting reinforcing ribs, and the triangle has good stability, which can improve the firmness of the reinforcing ribs, thereby improving the overall stability.
[0018] Preferably, a filling layer is provided between the hollow board body and the sound insulation board, and the filling layer is an aerogel block.
