Description

Technical Field

[0001] The utility model belongs to the technical field of plates, and particularly relates to a constrained damping vibration reduction and noise reduction plate. Background Technique

[0002] A plate is a flat rectangular building material plate of standard size, which is applied in the construction industry and used as a component for walls, ceilings or floors. It also mostly refers to metal plates forged, rolled or cast. It is divided into thin plates, medium plates, thick plates, extra-thick plates, and is usually made into flat rectangular building material plates of standard size. The damping vibration reduction and noise reduction plate is one of the plates, used for sound insulation and shock absorption. The functions of traditional damping vibration reduction and noise reduction plates are relatively single, the stability of the plates during installation needs to be improved, and they are easily damaged when exposed to bad weather. After retrieval, a patent with the application number 201921055569.2 discloses a constrained damping vibration reduction and noise reduction plate, which includes a plate main body and a strong adhesive. A fixing groove is opened at the bottom end of the plate main body, and there are two fixing grooves in total. Four chute plates are arranged at the bottom end of the plate main body. Two of the chute plates are located on both sides of the fixing groove. The chute plates and the plate main body are fixedly connected by bolts. A sliding block is slidably connected to the chute plate. The bottom end face of the sliding block is bolted with an inclined support rod, and a limit bolt is slidably connected to the sliding block. One end of each inclined support rod is bolted with a curved fixing plate.

[0003] However, during the actual use process, the applicant found that the plate surface of the curved fixing plate used to abut against the column is perpendicular to the plate surface of the plate main body. In this way, when the front surface of the plate main body is affected by wind in bad windy weather, the curved fixing plate will easily slide between the column and the column, so that the plate main body cannot be effectively supported, and the plate main body is still easily damaged and toppled by the wind. In view of this, we propose a constrained damping vibration reduction and noise reduction plate. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0005] The utility model relates to a constrained damping vibration reduction and noise reduction board, which comprises a board body. The board body includes a reinforcing core board. Sound-absorbing boards are symmetrically fixed to the front and rear sides of the reinforcing core board through a strong adhesive. A damping board is fixed to the side of the sound-absorbing board away from the reinforcing core board through a strong adhesive. U-shaped reinforcing brackets are fixedly connected to the front and rear sides of the board body. A double-headed screw is rotatably connected to the center position of the lower parts of the two U-shaped reinforcing brackets through a bearing. A column pressing plate is slidably connected to the inner wall of the lower part of the U-shaped reinforcing bracket. The thread directions at both ends of the double-headed screw are opposite, and both ends of the double-headed screw respectively thread through the two column pressing plates. The front end of the double-headed screw penetrates through the front U-shaped reinforcing bracket and is fixedly provided with an adjusting head. Fixing grooves are symmetrically formed at the bottom of the board body between the two column pressing plates.

[0006] Preferably, a guiding chute is formed on the inner wall of the lower part of the U-shaped reinforcing bracket.

[0007] Preferably, the column pressing plate slides along the guiding chute on the lower part of the U-shaped reinforcing bracket.

[0008] Preferably, an inner hexagonal groove is formed on the front end face of the adjusting head.

[0009] Preferably, a connecting protrusion is formed on one side of the board body, and a connecting groove is formed on the other side of the board body.

[0010] Preferably, the connecting protrusion is in fit connection with the connecting groove on the adjacent board body.

[0011] The utility model has the following beneficial effects:

[0012] For the constrained damping vibration reduction and noise reduction board of the utility model, the structural strength of the board body can be increased through the arrangement of the reinforcing core board, and the board body can be prevented from being easily damaged by force. By rotating the double-headed screw to drive the two column pressing plates to approach synchronously and making the two column pressing plates abut against the front and rear sides of the column inserted in the fixing groove, the acting force received by the front of the board body can be transmitted to the column through the U-shaped reinforcing bracket, and the board body can be further prevented from being damaged and toppled when affected by wind force, so that the board body can be more stable during use.

[0020] Please refer to Figures 1 - 3 As shown, the present utility model provides a technical solution:

[0021] A constrained damping vibration reduction and noise reduction board includes a plate body 1. The plate body 1 includes a reinforcing core plate 11. Sound-absorbing plates 12 are symmetrically fixed to the front and rear sides of the reinforcing core plate 11 through a strong adhesive 14. A damping plate 13 is fixed to the side of the sound-absorbing plate 12 away from the reinforcing core plate 11 through a strong adhesive 14. The setting of the reinforcing core plate 11 can increase the structural strength of the plate body 1 and prevent the plate body 1 from being easily damaged by force. The setting of the sound-absorbing plate 12 enables the plate body 1 to have the function of sound absorption and noise reduction. The setting of the damping plate 13 enables the plate body 1 to have the function of vibration reduction. A connecting protrusion 2 is provided on one side of the plate body 1, and a connecting groove 3 is provided on the other side of the plate body 1. The connecting protrusion 2 is in mating connection with the connecting groove 3 on the adjacent plate body 1. Through the cooperation of the connecting protrusion 2 and the connecting groove 3, it is convenient to align and join adjacent plate bodies 1. During use, adjacent plate bodies 1 can be aligned and joined through the cooperation of the connecting protrusion 2 and the connecting groove 3. Through the sound-absorbing plate 12 and the damping plate 13, the plate body 1 has the functions of sound absorption and vibration reduction.

[0022] On the front and rear sides of the plate body 1, U-shaped reinforcement brackets 4 are fixedly connected. Guide chutes are provided on the inner walls of the lower parts of the U-shaped reinforcement brackets 4. At the central positions of the lower parts of the two U-shaped reinforcement brackets 4, a double-headed screw rod 6 is rotatably connected through bearings. The inner walls of the lower parts of the U-shaped reinforcement brackets 4 are slidably connected with column pressing plates 7. The column pressing plates 7 slide along the guide chutes on the lower parts of the U-shaped reinforcement brackets 4. The thread directions at both ends of the double-headed screw rod 6 are opposite, and both ends of the double-headed screw rod 6 respectively thread through the two column pressing plates 7. The front end of the double-headed screw rod 6 penetrates through the front U-shaped reinforcement bracket 4 and is fixedly provided with an adjusting head 61. An inner hexagonal groove is provided on the front end face of the adjusting head 61. Fixed grooves 5 are symmetrically provided at the bottom of the plate body 1 between the two column pressing plates 7. By rotating the double-headed screw rod 6 to drive the two column pressing plates 7 to approach synchronously, and making the two column pressing plates 7 abut against the front and rear sides of the column inserted in the fixed groove 5, the force received on the front of the plate body 1 can be transmitted to the column through the U-shaped reinforcement bracket 4, further preventing the plate body 1 from being damaged and toppled under the action of wind force, making the plate body 1 more stable during use. During use, the column can be fixed in the fixed groove 5, and the adjusting head 61 can be rotated by an inner hexagonal wrench to drive the double-headed screw rod 6 to rotate. The rotation of the double-headed screw rod 6 can drive the two column pressing plates 7 to approach synchronously, and make the two column pressing plates 7 abut against the column surface. When the front of the plate body 1 is windward, at this time, the U-shaped reinforcement bracket 4 can support the plate body 1 and transmit the force received by the plate body 1 to the column, preventing the plate body 1 from being damaged and toppled by the wind.

[0023] Working principle: During use, the column can be fixed in the fixed groove 5, and the adjusting head 61 can be rotated by an inner hexagonal wrench to drive the double-headed screw rod 6 to rotate. The rotation of the double-headed screw rod 6 can drive the two column pressing plates 7 to approach synchronously, and make the two column pressing plates 7 abut against the column surface. The adjacent plate bodies 1 can be aligned and spliced through the cooperation of the connecting protrusions 2 and the connecting grooves 3. The column can be fixed in the fixed groove 5. The plate body 1 has the functions of sound absorption and vibration damping through the sound absorption plate 12 and the damping plate 13. When the front of the plate body 1 is windward, at this time, the U-shaped reinforcement bracket 4 can support the plate body 1 and transmit the force received by the plate body 1 to the column, preventing the plate body 1 from being damaged and toppled by the wind.
