Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention is described in detail below with reference to the attached drawings.
As shown in fig. 1 to 4, the high-performance autoclaved sand aerated sound insulation concrete block provided by the utility model comprises a main body 1 and a sound insulation structure, wherein the main body 1 is in a cuboid shape, the sound insulation structure comprises a sound absorption plate 2 and a sound insulation plate 3, the sound absorption plate 2 and the sound insulation plate 3 are respectively arranged on two long side walls of the main body 1, one end surface of the sound absorption plate 2, which is back to the main body 1, is provided with a plurality of sound absorption holes 21 at intervals, and a plurality of protrusions 22 are irregularly distributed on the inner side wall of the sound absorption holes 21.
Generally speaking, sound insulation is mainly used to insulate sounds outside a room so that the sounds do not affect the rest of people in the room. Therefore, the two long side walls of the sound-absorbing plate 2 and the sound-insulating plate 3 are respectively arranged on the two long side walls, the sound-absorbing plate 2 is positioned on the outer side of a room and used for reflecting the irregularly distributed bulges 22 after sound is transmitted from the outer side and enters the sound-absorbing hole 21, so that the frequency of mutual interference and collision of the sound is increased, and the effect of mutual offset is achieved, thereby achieving good sound-insulating effect. In addition, the sound insulation board 3 is further arranged for further increasing the sound insulation effect, and sound insulation of certain amplitude can be performed on the sound emitted in the room, so that the sound insulation effect is more comprehensive.
In this embodiment, the sound absorbing hole 21 has an arc-shaped cross section, and the protrusions 22 are distributed on the arc-shaped cross section, so that the sound waves are diffused more irregularly, and the sound insulation effect is achieved.
In the present embodiment, the shape of the protrusion 22 is a polyhedron, which has a better effect of changing the transmission path strength of sound than an arc surface, so that the sounds are easier to interfere and cancel each other.
In the present embodiment, the baffle 3 includes a frame 31 and a panel 32, and the panel 32, the frame 31 and the main body 1 enclose a sound-proof room 33. That is, after the sound passes through the main body 1, the sound insulation room 33 and the panel 32, the energy of the sound can be greatly consumed in the process by changing the transmission medium three times, thereby achieving the sound insulation effect. Specifically, the baffle 3 may be attached by standing on the surface of the body 1 with an adhesive after the body 1 is molded, or may be integrally molded.
In this embodiment, the top and the bottom of the main body 1 are respectively provided with a plurality of grooves 11, and the grooves 11 are used for increasing the roughness of the top and the bottom of the main body 1 when the present invention is stacked, so that the adhesive is easier to adhere, and a better bonding effect is achieved.
In this embodiment, one side of the main body 1 is provided with a positioning hole (not shown in the figure), the other side of the main body 1 is provided with a positioning piece 13, and the positioning piece 13 is used for being inserted into the positioning hole of another main body 1, so that the effect of positioning the adjacent main body 1 is achieved, and the subsequent stacking use is facilitated.
Specifically, the locating hole is located the non-center line position of 1 one side of main part lets the effect of location better for two baffle-boards 3 of main part 1 all lie in same one side, thereby have guaranteed the stability of the syllable-dividing effect of the wall of piling up the number.
Specifically, one end of the positioning element 13, which is far away from the main body 1, is provided with a positioning inclined surface 14, so that the positioning element 13 can be inserted into the positioning hole more easily.
Although the present invention has been described with reference to the above preferred embodiments, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the utility model as defined by the appended claims.
