Description

Technical Field

[0001] This utility model relates to the field of porous brick technology, specifically a sound-insulating and vibration-damping porous brick. Background Technology

[0002] With the continuous progress of society, a large number of porous bricks have gradually entered the market and are used by people. Porous bricks refer to bricks with visible internal channels and a porosity generally not less than 15%. They are mainly made from clay, shale, and fly ash, and are formed and fired. Porous bricks are mainly used in load-bearing parts. Their internal pores are generally small in diameter and numerous. The brick's shape is generally a right-angled hexahedron, and the bonding surface with mortar should have plaster grooves and mortar grooves to increase bonding strength.

[0003] Patent application number CN202021773466.2 discloses a heat-insulating porous brick, relating to the field of building materials technology. The heat-insulating porous brick includes a porous brick body, a left porous brick body, and a right porous brick body. The left porous brick body is located on the left side of the porous brick body, and the right porous brick body is located on the right side of the porous brick body. Simultaneously, the other two sides of the porous brick body, excluding the left and right sides, are respectively provided with a main side fixing body and a secondary side fixing body, located on opposite sides of the porous brick body. This accelerates the connection between bricks, improves work efficiency, and ensures the traditional heat insulation and constant temperature characteristics of porous bricks. However, this brick is still a single-piece brick, achieving only a single function, and cannot meet the application scenarios with higher requirements. For example, in a large band practice room, because the band contains many instruments, the vibrations and sounds generated during performance place higher demands on the wall's sound insulation and vibration reduction. Utility Model Content

[0004] To address the shortcomings of the existing technology, the purpose of this utility model is to provide a sound-insulating and vibration-damping porous brick. Through a modular design, the upper brick body, the lower brick body, and the connecting vibration-damping body cooperate to form a complete brick, thereby achieving multiple properties of sound insulation and vibration reduction.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A sound-insulating and vibration-damping porous brick, comprising: The upper brick body includes a first vibration damping cavity and a first connecting hole that is connected to the first vibration damping cavity. The first vibration damping cavity is provided with a force-dissipating and counteracting component. The lower brick body includes a second vibration damping cavity and a second connecting hole that is connected to the second vibration damping cavity. The first vibration damping cavity is provided with a force-dissipating and counteracting component. The force-dispersing component includes an outer frame and a row of force-dispersing plates filled in the outer frame. The force-dispersing plates form a row of honeycomb grid structure with each other, and the force-dispersing plates near the outer frame form insertion holes with the outer frame. A connecting cavity is formed between the first connecting hole and the second connecting hole. A connecting damping body is provided in the connecting cavity. The connecting damping body includes a damping block and a plug rod adapted to the plug hole. The plug rod is connected to the plug hole. Two side slots are provided on one side of the upper brick and the lower brick. The side slots can be adapted to external folding strips. The two opposing folding strips form sound-absorbing slots with the upper brick and the lower brick. Sound-absorbing cotton is inserted into the sound-absorbing slots.

[0006] As a preferred embodiment of the present invention, the first vibration damping cavity is located at the center of the upper brick body, and the second vibration damping cavity is located at the center of the lower brick body. The aspect ratio of the first vibration damping cavity is the same as that of the upper brick body, and the aspect ratio of the second vibration damping cavity is the same as that of the lower brick body.

[0007] As a preferred embodiment of the present invention, the first vibration damping cavity is located at the upper part of the upper brick body, the first connecting hole is located at the lower part of the upper brick body, the second vibration damping cavity is located at the lower part of the lower brick body, the second connecting hole is located at the upper part of the lower brick body, the bottom of the upper brick body is provided with a connecting rib protruding towards the lower brick body, and the top of the lower brick body is provided with a groove 203 that is recessed inward to accommodate the connecting rib, and the connecting rib is connected to the groove 203.

[0008] As a preferred embodiment of the present invention, the vibration damping block is a polystyrene foam filler, the vibration damping block has holes, the plug rod passes through the holes and extends out of both ends of the vibration damping block, and the two ends of the plug rod extend out of the vibration damping block and connect to the plug holes on the same side.

[0009] As a preferred embodiment of the present invention, the plug rod is an isosceles triangular cross-section plug rod, and a vibration damping layer is provided on the outer side of the plug rod.

[0010] As a preferred embodiment of the present invention, an adhesive layer is provided between the upper brick body and the lower brick body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The design of a split-type sound-insulating and vibration-damping porous brick optimizes the design of the whole brick into a split upper and lower brick body, with a connecting vibration-damping component between the upper and lower brick bodies. Compared with a one-piece brick, this improves the vibration-damping effect. At the same time, the split design is also easier to manufacture, as only the upper and lower brick bodies need to be produced separately, without creating higher challenges in the production requirements of the brick body due to the improved vibration-damping capacity.

[0012] Connecting the vibration damper reduces the transmission of sound vibrations, thus achieving a noise reduction effect.

[0013] Sound absorption and external sound insulation are achieved through sound-absorbing cotton. Attached Figure Description

[0025] A sound-insulating and vibration-damping porous brick includes a split design: an upper brick body 1 and a lower brick body 2. A first connecting hole 102 located at the lower part of the upper brick body 1 and a second connecting hole 202 located at the upper part of the lower brick body 2 form a connecting cavity. A vibration-damping material is filled and connected in the connecting cavity, providing vibration damping. Since the vibration-damping material is filled with polystyrene foam, and sound is the primary source of vibration in a band rehearsal room, the vibration damping also reduces the transmission of sound vibrations, thus achieving a sound-absorbing effect. Furthermore, an adhesive layer 9 is provided between the upper brick body 1 and the lower brick body 2, reinforcing the connection between them. Specifically, the adhesive layer 9 can contain structural adhesive. The upper brick body 1 includes a first vibration damping cavity 101 and a first connecting hole 102 that is connected to the first vibration damping cavity 101. The first vibration damping cavity 101 is provided with a force-dispersing counteracting component 4.

[0026] The lower brick body 2 includes a second vibration damping cavity 201 and a second connecting hole 202 that is connected to the second vibration damping cavity 201. The first vibration damping cavity 101 is provided with a force-dispersing counteracting component 4.

[0027] The force-dispersing component 4 includes an outer frame 401 and a row of force-dispersing plates 402 filled in the outer frame 401. The force-dispersing plates 402 form a row of honeycomb grid structure. The force-dispersing plates 402 near the outer frame 401 form insertion holes 403 with the outer frame 401.

[0028] A connecting cavity is formed between the first connecting hole 102 and the second connecting hole 202. A connecting damping body is provided within the connecting cavity. The connecting damping body includes a damping block 301 and a connecting rod 302 adapted to the connecting hole 403. The connecting rod 302 is inserted upwards into the connecting hole 403 and connected thereto. Through the connection between the connecting rod 302 and the connecting hole 403, a more stable connection is formed between the connecting damping body and the upper brick 1 and the lower brick 2. Simultaneously, the connecting rod 302 facilitates alignment, reducing the alignment time for workers when connecting the upper brick 1 and the lower brick 2, thus improving work efficiency.

[0029] Two side slots 6 are provided on one side of the upper brick body 1 and the lower brick body 2. The side slots 6 can be adapted to external folding strips 7. The two opposing folding strips and the upper brick body 1 and the lower brick body 2 form sound-absorbing slots 8, and sound-absorbing cotton is inserted into the sound-absorbing slots 8. Sound absorption and sound insulation are achieved by inserting sound-absorbing cotton.

[0030] The first damping cavity 101 is located at the center of the upper brick body 1, and the second damping cavity 201 is located at the center of the lower brick body 2. The length-to-width ratio of the first damping cavity 101 is the same as that of the upper brick body 1, and the length-to-width ratio of the second damping cavity 201 is the same as that of the lower brick body 2.

[0031] The first damping cavity 101 is located on the upper part of the upper brick body 1, and the first connecting hole 102 is located on the lower part of the upper brick body 1. The second damping cavity 201 is located on the lower part of the lower brick body 2, and the second connecting hole 202 is located on the upper part of the lower brick body 2. A connecting rib 103 protrudes from the bottom of the upper brick body 1 towards the lower brick body 2, and a groove 203 is recessed inward at the top of the lower brick body to accommodate the connecting rib 103. The connecting rib is connected to the groove 203. Since the damping block 301 and the damping cavity are interference-fitted, the groove 203 and the connecting rib make the connection between the upper brick body and the lower brick body more stable.

[0032] The vibration damping block 301 is filled with polystyrene foam. The vibration damping block 301 has a hole 3011. The plug rod 302 passes through the hole 3011 and extends out of both ends of the vibration damping block 301. After the two ends of the plug rod 302 extend out of the vibration damping block 301, they are connected to the plug hole 403 on the same side.

[0033] The plug rod 302 is a plug rod with an isosceles triangular cross section, and a vibration damping layer 3021 is provided on the outside of the plug rod 302.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
