DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions of this patent will be further described in detail below in conjunction with the specific embodiments.

[0018] Such as Figures 1-3As shown in the figure, the utility model provides a technical solution: a sound-insulating building board for construction, which includes a base board 1. A reinforcement layer 7 is provided on the base board 1. A sound-insulating layer 2 is provided on the reinforcement layer 7. A sound-insulating felt 3 is provided on the sound-insulating layer 2. By providing the sound-insulating felt 3, the sound-insulating felt 3 can effectively isolate noise and play a preliminary weakening role in the noise propagation process. The sound-insulating layer 2 includes a support board 21. The support board 21 is provided on the reinforcement layer 7. A number of fixing cylinders 22 are provided on the support board 21. The sound-insulating felt 3 is connected to the support board 21. The fixing cylinder 22 penetrates through the support board 21. Three noise reduction boards 24 are provided in the fixing cylinder 22. A number of honeycomb holes 25 are provided on the noise reduction board 24. Two sound-absorbing sponges 23 are provided in the fixing cylinder 22. By providing the sound-absorbing sponges 23, when sound waves enter the micropores of the sound-absorbing sponges 23, air molecules rub against the pore walls, causing the sound wave energy to gradually decay, thereby achieving the sound-absorbing effect;

[0019] The sound-absorbing sponges 23 are located between the two noise reduction boards 24. A compression-resistant layer 4 is provided on the sound-insulating felt 3. The compression-resistant layer 4 includes a galvanized steel plate 41. The galvanized steel plate 41 is provided on the sound-insulating felt 3. The galvanized steel plate 41 is connected to a fireproof layer 6. A number of grooves 42 are provided on the galvanized steel plate 41. By providing the galvanized steel plate 41 and the grooves 42, the galvanized steel plate 41 has good corrosion resistance. The groove 42 structure not only helps to destroy the straight propagation path of sound waves and improve the sound-insulating effect by reflecting and absorbing sound waves, but also improves the bending resistance of the building board. A fireproof layer 6 is provided on the compression-resistant layer 4. The fireproof layer 6 is made of ultra-fine glass wool. By providing the ultra-fine glass wool, the ultra-fine glass wool has a high melting point and is non-combustible, so it can effectively prevent the spread of fire, thereby meeting the requirements of environmental protection and fire prevention codes. A decorative layer 5 is provided on the fireproof layer 6.

[0020] The working principle of the utility model is as follows:

[0021] During use, the sound-insulating felt 3 has a high surface density and strong internal damping performance, so it is a new material for controlling the sound attenuation of noise in the transmission path. At the same time, since the through-hole diameters of the honeycomb holes 25 decrease in sequence, the noise is fully absorbed, reduced in noise, and silenced by the honeycomb holes 25 on the surface of the noise reduction board 24 and the internal sound-absorbing sponges 23, so that the sound waves can be absorbed and scattered to reduce the noise propagation, which is beneficial to achieving the double sound-insulating effect;

[0022] At the same time, under the mutual cooperation of the galvanized steel plate 41 and the grooves 42, the groove 42 structure not only helps to destroy the straight propagation path of sound waves and improve the sound-insulating effect by reflecting and absorbing sound waves, but also improves the bending resistance of the building board.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific circumstances.

[0024] The above describes the preferred embodiments of the present patent in detail. However, the present patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present patent.
