Description

Technical Field

[0001] The utility model belongs to the technical field of permeable bricks, and specifically refers to a permeable brick for sidewalks. Background Technique

[0002] Permeable bricks, also known as water-permeable bricks or Dutch bricks, are a type of green and environmentally friendly new building material. The raw materials mainly use cement, sand, slag, fly ash and environmentally friendly materials for high-pressure forming.

[0003] At present, permeable bricks are often directly placed, which is not conducive to the splicing and laying of permeable bricks. At the same time, after the permeable bricks are laid, they are prone to skew or large gaps, and the compressive performance is average. And because the main function of the permeable brick design is water permeability, it lacks other additional functions, such as noise absorption. Content of the Utility Model

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a permeable brick for sidewalks, which is used to solve the problems in the prior art that permeable bricks are not easy to lay, have poor compressive performance, and cannot absorb noise.

[0005] The technical solution adopted in this application is as follows:

[0006] This solution provides a permeable brick for sidewalks, including a permeable brick body;

[0007] It also includes: a permeable bottom plate provided at the bottom of the permeable brick body and a sound absorption structure provided inside the permeable brick body;

[0008] The permeable brick body includes a brick body and a permeable sound absorption plate. The brick body is made of colored stone epoxy permeable material. A fixing groove is provided at one end of the brick body, and a fixing block is provided at the other end of the brick body. The fixing block is matched with the fixing groove for connecting adjacent brick bodies. Anti-slip protrusions are provided on the surface of the brick body, and water discharge holes are provided on the anti-slip protrusions. The inside of the brick body is hollow and the bottom is open. The permeable sound absorption plate is fixedly provided at the bottom opening of the brick body. A compression beam is provided at the center of the permeable bottom plate. A card slot is provided at the bottom of the permeable sound absorption plate to match the compression beam, and the card slot extends to both sides of the brick body;

[0009] The sound absorption structure is a sound absorption tube, and the sound absorption tube is vertically arranged between the inner top of the brick body and the permeable sound absorption plate at the bottom. The sound absorption tube is provided with air holes on the top of the brick body.

[0010] As a preferred solution, the sound-absorbing tube includes long tubes and short tubes with different lengths. The long tubes are vertically penetrated and connected between the inner top of the brick body and the permeable sound-absorbing plate. The upper end of the short tube is open and the bottom end is closed, and the top is connected to the inner top of the brick body. A plurality of groups of air holes are evenly arranged and communicated with the tops of the long tubes and the short tubes respectively. There is a certain gap between the short tube and the permeable sound-absorbing plate at the bottom, and the short tubes are provided with different sizes and gaps from the permeable sound-absorbing plate at the bottom.

[0011] Further, a plurality of groups of permeable holes are evenly formed on the permeable bottom plate, and the permeable bottom plate is made of an anti-corrosion and compressive permeable material. The permeable sound-absorbing plate is provided with diversion holes, and the water discharge holes are arranged corresponding to the diversion holes. The permeable sound-absorbing plate is made of a porous sound-absorbing material. While having good sound-absorbing performance, due to the micropores formed on the surface, it can also achieve good water seepage effect. The porous sound-absorbing material is not limited to slag wool, glass fiber, rock wool, etc.

[0012] In the preferred solution, the cross-section of the sound-absorbing tube is circular or square. When sound waves are incident on the surface of the brick body, due to the effect of the brick body, a part of the sound waves are reflected, a part of the sound waves enter the interior of the brick body through the water discharge holes, and the inner wall of the brick body is used to reduce the transmitted sound energy. Another part of the sound waves enters the sound-absorbing tube inside the brick body through the air holes. When the incident wavelength matches the depth of the sound-absorbing tube, resonance occurs, and the sound waves oscillate in the cavity of the sound-absorbing tube, thereby consuming the sound energy and achieving the sound-absorbing effect.

[0013] The beneficial effects achieved by the present utility model with the above structure are as follows:

[0014] 1. Through the arrangement of the permeable bottom plate, it is convenient for operation during the laying process. There is a connection and fixing effect between adjacent brick bodies, preventing deviation. Moreover, the permeable brick body can transfer the corresponding pressing or folding force to the compressive beam, playing a good compressive role, and at the same time, the structure maintains good water permeability.

[0015] 2. By setting sound-absorbing tubes with different lengths, the sound waves oscillate in the cavity of the sound-absorbing tube, thereby consuming the sound energy and achieving the sound-absorbing effect, improving the noise absorption function. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Embodiment 1

[0027] Please refer to Figure 1 and Figure 3 As shown, this embodiment provides a permeable brick for sidewalks, including a permeable brick body 1. The permeable brick body 1 includes a brick body 11 and a permeable sound-absorbing plate 12. Anti-slip protrusions 13 are provided on the surface of the brick body 11, and drainage holes 14 are opened on the anti-slip protrusions 13. The interior of the brick body 11 is hollow and the bottom is open. The permeable sound-absorbing plate 12 is fixedly arranged at the bottom opening of the brick body 11. A fixing groove 4 is opened at one end of the brick body 11, and a fixing block 5 is provided at the other end of the brick body 11. The fixing block 5 is arranged to match the fixing groove 4 for connecting adjacent brick bodies 11.

[0028] As Figure 1 shown, this solution also includes a permeable bottom plate 2 provided at the bottom of the permeable brick body 1. A compressive beam 21 is provided at the center of the permeable bottom plate 2. A card slot 16 is provided at the bottom of the permeable sound-absorbing plate 12 to match the compressive beam 21, and the card slot 16 extends to both sides of the brick body 11.

[0029] Among them, the brick body 11 is made of colored stone epoxy permeable material, the permeable bottom plate 2 is made of anti-corrosion and compressive permeable material, and the permeable sound-absorbing plate 12 is made of porous sound-absorbing material. While having good sound-absorbing performance, due to the micropores opened on the surface, it can also achieve good water seepage effect. The porous sound-absorbing material is not limited to slag wool, glass fiber, rock wool, etc. A number of groups of permeable holes 22 are evenly opened on the permeable bottom plate 2, a diversion hole 15 is opened on the permeable sound-absorbing plate 12, and the drainage hole 14 is arranged corresponding to the diversion hole 15.

[0030] After the corresponding permeable bottom plate 2 is laid, the permeable brick body 1 can transfer the corresponding pressing or folding force to the compression beam 21, playing a good role in compression resistance. Through the setting of the permeable bottom plate 2, it is convenient for operation during the laying process. The adjacent brick bodies 11 are connected and fixed through the fixing blocks 5 and the fixing grooves 4 to prevent deviation. At the same time, the structural settings of the material and the holes and grooves can maintain good water permeability. In addition, it is convenient to take out and replace the permeable brick body 1, which is convenient for replacing the permeable brick body 1 during subsequent road maintenance.

[0031] As Figure 2 and Figure 4 shown, this solution also includes a sound absorption structure 3 provided inside the permeable brick body 1, which is used to achieve the effect of absorbing noise.

[0032] Among them, the sound absorption structure 3 is a sound absorption tube 31. The sound absorption tube 31 is vertically arranged between the permeable sound absorption plates 12 at the inner top and bottom of the brick body 11, and the sound absorption tube 31 is provided with air holes 32 on the top of the brick body 11.

[0033] As Figure 4 shown, the sound absorption tube 31 includes a long tube 311 and a short tube 312 with different lengths. The long tube 311 penetrates up and down and is connected and arranged between the inner top of the brick body 11 and the permeable sound absorption plate 12. The upper end of the short tube 312 is open and the bottom end is closed, and the top is connected to the inner top of the brick body 11. The air holes 32 are evenly arranged in multiple groups and are respectively communicated with the tops of the long tube 311 and the short tube 312. There is a certain gap between the short tube 312 and the permeable sound absorption plate 12 at the bottom, and multiple short tubes 312 are provided with different sizes and different distances from the permeable sound absorption plate 12 at the bottom.

[0034] As a preferred embodiment, the cross-section of the sound absorption tube 31 is circular or square.

[0035] When using this structure, when sound waves are incident on the surface of the brick body 11, due to the effect of the brick body 11, a part of the sound waves are reflected, a part of the sound waves enter the interior of the brick body 11 through the water outlet holes 14, and the inner wall of the brick body 11 is used to reduce the transmitted sound energy. Another part of the sound waves enter the sound absorption tube 31 inside the brick body 11 through the air holes 32. By setting the sound absorption tubes 31 with different lengths, when the incident wavelength matches the depth of the sound absorption tube 31, resonance occurs, and the sound waves oscillate in the cavity of the sound absorption tube 31 to consume the sound energy, achieving the effect of sound absorption and improving the noise absorption function.

[0036] It should be noted that although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, without departing from the spirit of the present invention, without creative design, the structural forms and embodiments similar to this technical solution should all fall within the protection scope of the present invention.
