Description

Technical Field

[0001] This utility model relates to the field of sound insulation board technology, specifically to a sound insulation board with good sound insulation effect. Background Technology

[0002] Sound insulation panels are building materials that block or absorb sound wave transmission through material combinations and structural design. They are widely used in building walls, industrial equipment soundproof enclosures, traffic noise barriers, and other fields. However, in traditional sound insulation panels, the joints are prone to becoming weak points in sound insulation during splicing. The main reasons include:

[0003] Rigid connection and stress concentration: Traditional sound insulation panels are mostly fixed directly with screws, resulting in rigid contact at the connection. Sound waves are transmitted through structural vibration, which reduces the overall sound insulation performance.

[0004] Insufficient sealing: The joints lack elastic sealing material, and tiny gaps can cause air leakage, which is especially noticeable in low-frequency noise environments.

[0005] Therefore, it is necessary to design a soundproofing panel with good sound insulation effect to improve the sound insulation effect at the joint of the soundproofing panel. Utility Model Content

After the two sound insulation boards are spliced ​​together, the "L"-shaped grooves on the two sound insulation boards merge to form a groove.

[0024] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-5 The present invention provides a technical solution: a sound insulation board with good sound insulation effect, including a sound insulation board 1 and a fixing plate 18 and a connecting plate 2 disposed between two adjacent sound insulation boards 1. The fixing plate 18 and the connecting plate 2 are respectively located on the front and rear sides of the sound insulation board 1, and are used to connect and fix the sound insulation board 1.

[0026] The sound insulation panel 1 includes a protective layer 3, a sound insulation layer 4, and a decorative layer 5 arranged sequentially.

[0027] The protective layer 3 is made of galvanized steel sheet or high-density PVC sheet, and is used to provide mechanical protection and waterproof function.

[0028] The sound insulation layer 4 includes a damping layer 6 and a sound-absorbing layer 7, with the damping layer 6 located on the side closest to the protective layer 3.

[0029] The damping layer 6 is made of high-density rubber or butyl rubber, and the thickness of the damping layer 6 is 5-8mm. It is used to block the vibration of low-frequency sound waves.

[0030] The sound-absorbing layer 7 uses porous materials, including but not limited to rock wool, glass fiber or polyester fiberboard, to absorb mid- to high-frequency sound waves.

[0031] Decorative layer 5 uses fire-resistant gypsum board or fabric finish, which has a certain sound wave reflection effect.

[0032] The layers are connected by elastic adhesive, thus achieving a buffering effect against vibration.

[0033] The four sides of the sound insulation layer 4 extend outward to form a connecting frame 8. The connecting frame 8 is a rectangular frame. The thickness of the connecting frame 8 is less than the thickness of the sound insulation board 1, so that "L"-shaped grooves are formed at the junctions of the two sides of the connecting frame 8 with the sound insulation board 1 along the thickness direction.

[0034] After the two sound insulation panels 1 are spliced ​​together, the "L"-shaped grooves on the two sound insulation panels 1 merge to form a groove 9, and the fixing plate 18 and the connecting plate 2 are located in the front and rear grooves 9 respectively.

[0035] The connecting frame 8 has several grooves 10 on the side away from the sound insulation board 1. The grooves 10 are in the shape of a dovetail. At the same time, after the two sound insulation boards 1 are combined, the grooves 10 on the connecting frame 8 are combined to form groove 12.

[0036] Limiting blocks 11 are fixedly connected to the corresponding grooves 12 on the fixing plate 18 and the connecting plate 2. The limiting blocks 11 are adapted to the grooves 12, and the thickness of the limiting blocks 11 is 1 / 2 of the grooves 12.

[0037] Rubber sealing strips are embedded on the contact surfaces of the limiting block 11 and the groove 3 12 to fill the gap between the limiting block 11 and the groove 3 12.

[0038] The outer surface of the connecting frame 8 is covered with a fixing layer made of alloy steel, which is used to improve the firmness of the connection of the sound insulation panel 1.

[0039] The fixing plate 18, the connecting plate 2, and the limiting block 11 are all made of alloy steel. The fixing plate 18 is located in the groove 9 on the side of the sound insulation plate 1 close to the protective layer 3, and the connecting plate 2 is located in the groove 9 on the side of the sound insulation plate 1 away from the protective layer 3. The fixing plate 18 is fixed to the wall by bolts.

[0040] The limiting block 11 on the fixed plate 18 has a sound insulation cavity 14 on the side close to the fixed plate 18, and the limiting block 11 on the connecting plate 2 has a sound insulation cavity 21 on the side close to the connecting plate 2. Both the sound insulation cavity 14 and the sound insulation cavity 21 are filled with sound insulation cotton.

[0041] The connecting plate 2 has several sound-absorbing holes 13 on the side near the connecting frame 8, and the sound-absorbing holes 13 are arranged in an array. The limiting block 11 on the connecting plate 2 has several sound-absorbing holes 15 on the side away from the connecting plate 2, and the sound-absorbing holes 15 are arranged in an array. The sound-absorbing holes 15 are connected to the sound insulation cavity 21.

[0042] The fixed plate 18 has several sound-absorbing holes 19 on the side near the connecting frame 8, and the sound-absorbing holes 19 are arranged in an array. The limiting block 11 on the fixed plate 18 has several sound-absorbing holes 20 on the side away from the fixed plate 18, and the sound-absorbing holes 20 are arranged in an array. The sound-absorbing holes 20 are connected to the sound insulation cavity 14.

[0043] Sound-insulating rubber pads are embedded on the side where the connecting frame 8, the fixing plate 18, and the connecting plate 2 contact, thereby protecting the contact surface between the connecting plate 2 and the connecting frame 8 and providing vibration buffering, as well as a certain sound insulation effect.

[0044] Sound-absorbing holes 13, 15, 19, and 20 are all conical holes with a diameter that gradually decreases from 8mm to 3mm. The smaller end of each of the sound-absorbing holes 13, 15, 19, and 20 faces the wall to improve sound absorption and prevent standing waves from forming.

[0045] Sound-absorbing holes 13, 15, 19, and 20 are all filled with sound-absorbing cotton, which adopts an aerogel composite structure.

[0046] The limiting block 11 on the fixed plate 18 has a threaded hole 16, which is not connected to the sound insulation cavity 14.

[0047] A stud is provided through the sound insulation cavity 21 of the limiting block 11 on the connecting plate 2. A threaded hole 17 is provided at the center of the stud corresponding to the threaded hole 16. The threaded hole 16 and the threaded hole 17 are connected by bolts, thereby connecting and fixing the fixing plate 18 and the connecting plate 2.

[0048] In this embodiment, the fixing plate 18 is fixed to the wall with bolts, and then the sound insulation plate 1 is connected to the fixing plate 18 through the tenon and mortise structure of the groove 2 10 and the limiting block 11.

[0049] After the two adjacent sound insulation panels 1 are connected to the fixing plate 18, the connecting plate 2 is placed in the groove 9 formed by the merger, and is screwed to the threaded hole 16 and the threaded hole 17 by bolts, thereby connecting and fixing the fixing plate 18 and the connecting plate 2.

[0050] By setting sound insulation cavity 14, sound insulation cavity 21, sound absorption hole 13, sound absorption hole 25, sound absorption hole 319, and sound absorption hole 420, the sound insulation effect at the joint of the sound insulation panel 1 is improved.
