[0001] The utility model relates to the technical field of building materials, and more specifically, it relates to a sound-insulating building board. Background Art

[0002] A building board is a material widely used in construction projects. It is usually a flat rectangular plate, mainly used for laying walls, ceilings or floors, and can also be a metal plate formed by forging, rolling or casting. In different building parts, the building board plays different functions, such as foundation raft plates, floor slabs, floors, floor slabs, parapet walls and partition walls, etc.

[0003] However, high-rise buildings in the city are usually built beside roads, and the running cars and city gatherings will continuously generate a large amount of noise. These noises cannot be effectively blocked and absorbed by the building board, so that the continuously generated noise will be continuously transmitted indoors, thus affecting people's living and working environments indoors.

[0004] Therefore, a new solution needs to be proposed to solve the problem of poor sound insulation effect of the building board. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a sound-insulating building board, and the sound insulation effect of the building board is enhanced through a new structural setting.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a sound-insulating building board, including a building board body, the building board body is composed of a sound insulation layer and panel one and panel two on both sides thereof, a plurality of noise reduction boards are arranged on the side of panel one away from the sound insulation layer, grooves one are opened at both ends of the length of the noise reduction boards, an elastic strip is clamped in a plurality of grooves one, a sound absorption board is clamped in the area where the elastic strip is located between adjacent noise reduction boards, a depression is opened in the area of panel one between adjacent noise reduction boards, and adjacent noise reduction boards and the depression and the sound absorption board therebetween form a refraction space.

[0010] The present utility model is further configured as follows: on the side of the panel two away from the sound-insulating layer, there are a number of connecting rods fixed to the wall, and a sound-insulating space is formed between the adjacent connecting rods, the panel two and the wall.

At the same time, by reducing the contact area between the building board body and the wall through the sound-insulating space, the transmission of the vibration energy in the sound wave is reduced. Through the multiple weakening of the sound, an efficient sound-insulating effect is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The present utility model will be described in detail below with reference to the drawings and embodiments.

[0018] Embodiment: A sound-insulating building board, as Figure 1 and Figure 3 shown, includes a building board body 1. The building board body 1 is composed of a sound-insulating layer 2 and a panel one 3 and a panel two 4 on both sides thereof. The length and width of the sound-insulating layer 2 are respectively the same as the length and width of the panel one 3 and the length and width of the panel two 4. The panel one 3 and the panel two 4 are symmetrically arranged along the thickness direction of the building board body 1. The sound-insulating layer 2 and the panel one 3 are staggered along the length direction of the building board body 1, so that depressions 9 and protrusions are respectively formed at both ends of the length of the building board body 1, facilitating the mutual clamping of multiple building board bodies 1 to form a sound-insulating surface with the required area.

[0019] As Figures 1 - 3 shown, a plurality of rectangular noise reduction boards 5 are provided on the side of the panel one 3 away from the sound-insulating layer 2. The plurality of noise reduction boards 5 are symmetrically arranged along the length direction of the sound-insulating layer 2. An arc-shaped depression 9 is formed in the area on the side of the panel one 3 away from the sound-insulating layer 2 and between adjacent noise reduction boards 5. The distance between adjacent noise reduction boards 5 is the same as the width of the depression 9. The plurality of depressions 9 are integrally formed on the panel one 3 by an extruder. The plurality of noise reduction boards 5 are fixed on the panel one 3 by a welding process. A rectangular groove one 6 is symmetrically formed at both ends of the length of the noise reduction board 5. A circular elastic strip 7 is clamped in the plurality of grooves one 6. A rectangular sound-absorbing board 8 is clamped in the area of the elastic strip 7 between adjacent noise reduction boards 5. A rectangular groove two 11 is symmetrically formed at both ends of the length of the sound-absorbing board 8. The noise reduction board 5 and the sound-absorbing board 8 have the same length. The depths of the groove one 6 and the groove two 11 are the same and greater than the diameter of the elastic strip 7, so that the groove two 11 at both ends of the sound-absorbing board 8 can be mutually clamped with the elastic strip 7. After being stretched, the elastic strip 7 is simultaneously mutually clamped with the plurality of grooves one 6 and the plurality of grooves two 11, preventing the elastic strip 7 from falling out of the groove one 6 or the groove two 11.

[0020] As Figures 1 - 3 shown, the elastic strip 7 is made of rubber material, and the rubber material has good elasticity and elastic recovery. When sound waves contact the plurality of sound-absorbing boards 8, the plurality of sound-absorbing boards 8 clamped on the elastic strip 7 will vibrate under the influence of the sound wave vibration. At this time, the plurality of sound-absorbing boards 8 can effectively absorb and consume the vibration energy in the sound waves to reduce the sound intensity. The sound-insulating layer 2 is made of glass wool. The glass wool has a special porous structure. The complex pore structure inside the sound-insulating layer 2 increases the contact area between the sound waves and the sound-absorbing boards 8, and at the same time enables the sound waves to be reflected and refracted multiple times in the sound-insulating layer 2, further enhancing the sound-insulating effect of the sound-insulating layer 2. The glass wool has good weather resistance, making the sound-insulating layer 2 suitable for use in outdoor environments.

[0021] As Figure 1 and Figure 3As shown, several noise reduction plates 5 and several sound absorption plates are arranged alternately along the length direction of the sound insulation layer 2. The distance between adjacent noise reduction plates 5 is greater than the thickness of the sound absorption plate 8. The width of the sound absorption plate 8 is smaller than the width of the noise reduction plate 5. One end of the sound absorption plate 8 far from the sound insulation layer 2 and one end of the noise reduction plate 5 far from the sound insulation layer 2 are located on the same horizontal plane. Thus, two adjacent noise reduction plates 5 and the recess 9 and the sound absorption plate 8 therebetween form a refraction space 10 with a U-shaped cross-section. The sound waves entering the refraction space 10 will be continuously refracted and reflected, further weakening the sound intensity. Through several sound absorption plates 8 and several refraction spaces 10, the sound intensity is greatly weakened before entering the building board body 1.

[0022] As Figure 1 and Figure 2 shown, the thicknesses of the first panel 3 and the second panel 4 are the same. The thickness of the sound insulation layer 2 is twice that of the first panel 3. The sound insulation layer 2 is made of polyester fiber cotton. The special porous structure of the polyester fiber cotton enables the made sound insulation layer 2 to have a good sound absorption effect. Through the sound insulation layer 2, the sound transmitted from the first panel 3 can be weakened again. By increasing the thickness of the sound insulation layer 2, the sound absorption effect is further improved. The polyester fiber cotton has a good heat insulation and sound insulation effect, enabling the sound insulation layer 2 to effectively block the temperature transfer on both sides thereof and improving the use effect of the building board body 1. On the side of the second panel 4 far from the sound insulation layer 2, there are two connecting rods 12 fixed to the wall. An acoustic space 13 is formed between the adjacent connecting rods 12, the second panel 4 and the wall. Through the acoustic space 13, the air content between the building board body 1 and the wall is increased. The sound propagation effect in the air is poor. Through the acoustic space 13, the energy consumption during sound propagation is increased. At the same time, through the acoustic space 13, the contact area between the building board body 1 and the wall is reduced, and the transmission of the vibration energy in the sound wave is reduced. Through weakening the sound multiple times, an efficient sound insulation effect is achieved. The connecting rods 12, the first panel 3, the second panel 4 and the sound insulation layer 2 are all made of aluminum alloy material. The aluminum alloy material has the characteristics of light weight and high strength, ensuring the strength of the overall structure.

[0023] Working principle: When sound waves contact a number of sound-absorbing panels 8, the several sound-absorbing panels 8 clamped on the elastic strips 7 will vibrate under the influence of the vibration of the sound waves, thereby absorbing and consuming the vibration energy in the sound waves to reduce the sound intensity. The sound-absorbing effect of the sound-absorbing panels 8 is further improved through the porous structure of the glass wool. The several refraction spaces 10 can reflect and refract the sound waves, thereby reducing the sound intensity entering the first panel 3. The porous structure of the polyester fiber cotton enables the made sound insulation layer 2 to weaken the sound intensity transmitted from the first panel 3. The sound insulation space 13 increases the air content between the building board body 1 and the wall. The sound transmission effect in the air is poor, thereby reducing the sound transmission effect. At the same time, the contact area between the building board body 1 and the wall surface is reduced through the sound insulation space 13, and the transmission of the vibration energy in the sound waves is reduced. An efficient sound insulation effect is achieved through the multiple weakening of the sound.

[0024] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
