Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation bricks, in particular to high-efficiency sound insulation bricks for buildings. Background Art

[0002] In the prior art, artificial small blocks used in construction are divided into sintered bricks (mainly clay bricks) and unsintered bricks (lime sand bricks, fly ash bricks, etc.), commonly known as bricks. Clay bricks are made of clay (including shale, coal gangue and other powder materials) as the main raw material, and are processed, molded, dried and baked. With the improvement of the functional requirements of building materials in society, traditional bricks can no longer meet the use needs, especially for buildings located in downtown areas, which have certain requirements for sound insulation. A Chinese patent discloses a new type of high-efficiency sound insulation brick for construction (authorization announcement number CN213015074U). This patented technology can achieve multi-level sound insulation effects by setting the first sound insulation cotton and the second sound insulation cotton inside the brick body, thereby effectively improving the sound insulation effect of the sound insulation brick. However, the sound insulation effect of the sound insulation cotton is general, and the sound insulation brick is higher than that of ordinary bricks. The sound insulation brick is prone to shaking during the wall-building process. Therefore, those skilled in the art provide high-efficiency sound insulation bricks for construction to solve the problems raised in the above background technology. Utility Model Content

[0004] A noise reduction hole for reducing noise is provided in the second convex block. The noise reduction hole runs through the bottom of the second groove from the top of the second convex block. The noise reduction hole plays a role in reducing the noise level.

[0005] Preferably: four rows of noise reduction holes are evenly arranged, and each row is evenly spaced with six holes. An elastic tube is fixed to the inner wall of the noise reduction hole, and the elastic tube together achieves a buffering effect.

[0006] Preferably: a placement cavity 1 is opened inside the sound insulation brick body just in front of the first row of noise reduction holes, and a moisture-proof board is provided inside the placement cavity 1. The moisture-proof board is located at the outermost layer and is used to isolate moisture vapor outside the building.

[0007] Preferably: a second placement cavity is provided inside the sound insulation brick body between the first row of noise reduction holes and the second row of noise reduction holes, and a gypsum board is provided inside the second placement cavity. The gypsum board has a good heat preservation effect while soundproofing.

[0008] Preferably: a placement cavity three is opened inside the sound insulation brick body between the second row of noise reduction holes and the third row of noise reduction holes, and a sound absorbing board is arranged inside the placement cavity three, which plays a role in greatly absorbing high-frequency noise.

[0009] Preferably: a placement cavity four is opened inside the sound insulation brick body between the third row of noise reduction holes and the fourth row of noise reduction holes, and high-elastic sound-absorbing cotton is arranged inside the placement cavity four, and the high-elastic sound-absorbing cotton is used to absorb noise of different frequency bands.

[0010] Preferably: a placement cavity five is provided inside the sound insulation brick body directly behind the fourth row of noise reduction holes, and a honeycomb aluminum plate is provided inside the placement cavity five, which plays a good flame retardant and fireproof role.

[0011] Preferably: four buffer through holes are evenly spaced inside the first protrusion, the buffer through holes pass through the front and rear sides of the first protrusion, and elastic tubes are provided inside the buffer through holes. The buffer through holes cooperate with the elastic tubes to improve the toughness of the interface of the sound insulation brick and prevent the interface of the sound insulation brick from expanding and fracture.

[0012] Technical effects and advantages of the utility model:

[0013] In the utility model, when the sound insulation bricks are used to build a wall horizontally, the convex block 1 on the right side of a sound insulation brick body is butted end to end with the groove 1 on the left side of another sound insulation brick body; when the sound insulation bricks are used to build a wall vertically, the convex block 2 on the top of a sound insulation brick body is butted end to end with the groove 1 on the bottom of another sound insulation brick body, so as to achieve a stable wall building effect, which is beneficial to improving the safety and work efficiency of the building;

[0014] The moisture-proof board located at the outermost layer of the sound insulation brick body is used to isolate the moisture outside the building to prevent moisture from damaging the internal structure of the sound insulation brick body. The gypsum board behind it has a good thermal insulation effect. After the initial noise reduction of the moisture-proof board and the gypsum board, the noise is transmitted to the sound-absorbing board. The sound-absorbing board greatly absorbs the high-frequency noise. The high-elastic sound-absorbing cotton behind the sound-absorbing board absorbs the remaining high-frequency noise and low-frequency noise.

[0015] In this multi-level noise reduction process, the noise reduction holes play an auxiliary noise reduction role. The principle of noise reduction holes is based on the wave nature of acoustics. When noise waves pass through the noise reduction holes, refraction, interference, and diffraction will occur, thereby changing the propagation direction and path of the noise waves, achieving the effect of reducing noise. This sound insulation brick has good sound insulation effect and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
