Detailed Description

In the following, an embodiment of the present invention will be described in detail with reference to the drawings, but it should be understood that the scope of the present invention is not limited by the embodiment.

As shown in fig. 1 to 4, an embodiment of the present invention provides a sound-absorbing fire-proof plate, which includes a substrate 1 having a double-layer plate structure with a gap;

a sound absorbing layer provided between the two substrates 1;

the fireproof layer 2 is arranged on the plate surface of the substrate 1, which is not in contact with the sound absorption layer; and

a decorative layer 3, the decorative layer 3 being provided on a side of the fire-retardant layer 2 not in contact with the substrate 1;

further, the decorative layer 3 is a polyester fiber board;

further, the substrate 1 is a glass magnesium plate;

as shown in fig. 1, the fire-proof plate is further provided with a sealing plate 10, and the sealing plate 10 can prevent dust, rainwater and the like from entering the interior of the fire-proof plate, so that a dry environment in the interior of the fire-proof plate is maintained, and the sound absorption effect is improved;

the sound absorption layer comprises a plurality of hollow supporting pieces 4, first sound absorption cotton 5 arranged in the supporting pieces 4 and second sound absorption cotton 6 arranged between the two supporting pieces 4;

the second sound absorption cotton 6 plays a main sound absorption role, when sound is transmitted to the second sound absorption cotton 6, a part of sound enters the first sound absorption cotton 5 through the air holes 9 and is absorbed by the first sound absorption cotton 5;

a first limiting block 7 and a second limiting block 8 for fixing the supporting piece 4 are respectively arranged on the two base plates 1;

a plurality of air holes 9 are formed in the base plate 1 and the support piece 4;

as shown in fig. 1, the air holes 9 on the two substrates 1 are staggered, and the support member 4 is also provided with the air holes 9, so as to extend the path of the sound wave and achieve better sound absorption effect;

the supporting piece 4 is of a cylindrical structure and is triangular prism in shape; the support member 4 can play a role of sufficient support, can provide sufficient compressive resistance, and improves the upper limit of the compressive resistance of the fireproof plate;
