Abstract
Description
Technical Field
[0001] This invention relates to the field of building structure engineering technology, and in particular to a noise-insulating block, a soundproof wall, and an assembly method. Background Technology
[0002] Sound is a sound wave produced by the vibration of an object; the sound source is the object that produces the vibration. Sound waves propagate in the form of waves and can be perceived by the auditory organs of humans or animals. However, noise pollution from construction, transportation, and industrial production is becoming increasingly serious, necessitating the use of noise-reducing and sound-insulating walls for the exterior walls of engineering buildings.
[0003] In related technologies, existing building soundproof walls mainly include glass sound barriers, concrete sound barriers, metal sound barriers, and PVC panel barriers. By constructing the above-mentioned enclosed sound barrier walls around different corresponding sound sources, the propagation of sound waves is blocked, thereby achieving the effect of isolation and noise reduction.
[0004] Conventional sound barriers employing relevant technologies offer various options. Glass sound barriers offer good light transmission but poor sound insulation; concrete sound barriers provide good sound insulation but are bulky and heavy, requiring sophisticated construction; metal sound barriers offer good sound insulation but are expensive and prone to corrosion; PVC panels are lightweight and inexpensive but have complex structures, poor durability, and only moderate sound insulation. Furthermore, when noise reduction is applied to areas such as air conditioning units, rebar cutting sheds, and large servers, the generation of significant heat or toxic gases necessitates sound barriers with good heat dissipation and smoke extraction capabilities, making fully enclosed designs impractical. This results in challenging construction and poor noise reduction performance. Summary of the Invention
[0005] This invention provides a noise-insulating block, a soundproof wall, and an assembly method that balances noise insulation performance with ventilation and heat dissipation capabilities, significantly reducing construction difficulty. The technical solution is as follows:
[0006] In a first aspect, embodiments of the present invention provide a noise-insulating block, the noise-insulating block comprising: a block body,
[0007] The block comprises six noise-insulating plates, the sides of which are connected perpendicularly to each other to form a regular hexahedron structure with an inner cavity, and each noise-insulating plate has a circular through hole at its center that communicates with the inner cavity.
[0008] Optionally, the ratio of the thickness to the side length of the noise-insulating plate is 1 / 30, and the ratio of the radius of the circular through hole to the side length of the noise-insulating plate is 1 / 12.
[0009] Optionally, the six noise-insulating panels include two opposing wall panels and four splicing plates disposed between the two wall panels. At least one of the four splicing plates is provided with a limiting protrusion, and at least one of the remaining three splicing plates is provided with a limiting groove that matches the limiting protrusion.
[0010] Optionally, the limiting protrusion is in the shape of an arc-shaped strip.
[0011] Optionally, two limiting protrusions are provided, and the two limiting protrusions are symmetrically arranged on both sides of the circular through hole.
[0012] Alternatively, the block can be a foam ceramic structural component.
[0013] Secondly, embodiments of the present invention provide a soundproof wall, comprising a plurality of noise-insulating blocks as described in the first aspect, wherein the blocks of the plurality of noise-insulating blocks are joined together and fixedly connected by noise-insulating plates, and the circular through holes on two adjacent noise-insulating plates are coaxially connected to form a wall.
[0014] Optionally, the soundproof wall includes a plurality of parallel wall sections, wherein the side lengths of the blocks in the plurality of wall sections are different.
[0015] Optionally, the noise-insulating panels that are joined together between two adjacent blocks are fixed by cement bonding.
[0016] Thirdly, embodiments of the present invention also provide an assembly method applicable to the soundproof wall described in the second aspect above, the assembly method comprising:
[0017] Select blocks with corresponding noise insulation plate side length, thickness, and circular through-hole radius based on the noise frequency;
[0018] Multiple noise-insulating blocks are joined and fixed together by noise-insulating panels, so that the circular through holes on two adjacent noise-insulating panels are coaxially connected to form a wall.
[0019] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following:
[0020] This noise-insulating block is a cubic structure composed of six noise-insulating panels made of noise-insulating material. Its internal cavity is a cubic hollow structure defined by the inner walls of the six noise-insulating panels. By stacking multiple blocks sequentially, with adjacent blocks joined together by the outer walls of the noise-insulating panels and fixed together using common building adhesives such as cement, a soundproof wall structure can be formed. Each block has a circular through-hole at the center of its six noise-insulating panels. The entire block forms a phonon crystal structure; when sound waves enter the internal cavity through the circular through-holes, they undergo intense compression and expansion, thus dissipating sound energy and creating a band gap. By adjusting the side length and thickness of the noise-insulating panels to customize the internal cavity specifications, noise insulation effects can be achieved for sound waves within a specific frequency range. Meanwhile, the circular through holes on the noise insulation panel can also enable communication between the two sides of the wall m, as well as between multiple blocks. When designing its size, it can also be adjusted according to the noise frequency of the sound source and the ventilation and heat dissipation requirements to achieve the ventilation and heat dissipation effect. When assembling the wall, it can be built in a fully enclosed manner around the sound source without the need for additional heat dissipation and smoke exhaust structures. It can balance its ventilation and heat dissipation capacity while ensuring the noise insulation effect, and greatly reduce the construction difficulty. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0034] In related technologies, existing building soundproof walls mainly include glass sound barriers, concrete sound barriers, metal sound barriers, and PVC panel barriers. By constructing the above-mentioned enclosed sound barrier walls around different corresponding sound sources, the propagation of sound waves is blocked, thereby achieving the effect of isolation and noise reduction.
[0035] Conventional sound barriers employing relevant technologies offer various options. Glass sound barriers offer good light transmission but poor sound insulation; concrete sound barriers provide good sound insulation but are bulky and heavy, requiring sophisticated construction; metal sound barriers offer good sound insulation but are expensive and prone to corrosion; PVC panels are lightweight and inexpensive but have complex structures, poor durability, and only moderate sound insulation. Furthermore, when noise reduction is applied to areas such as air conditioning units, rebar cutting sheds, and large servers, the generation of significant heat or toxic gases necessitates sound barriers with good heat dissipation and smoke extraction capabilities, making fully enclosed designs impractical. This results in challenging construction and poor noise reduction performance.
[0036] Figure 1 This is a three-dimensional structural diagram of a noise-insulating block provided in an embodiment of the present invention. Figure 2 This is a front view structural diagram of a noise-insulating block provided in an embodiment of the present invention. Figure 3 yes Figure 2 A schematic diagram of the cross-section at point AA. (See diagram below.) Figures 1 to 3 As shown, through practice, this embodiment of the invention provides a noise-insulating block, wherein the noise-insulating block includes a block body 1.
[0037] The block 1 includes six noise-insulating plates 11. The sides of the six noise-insulating plates 11 are connected perpendicularly to each other to form a regular hexahedron structure with an inner cavity 1a. Each noise-insulating plate 11 has a circular through hole 111 at its center that communicates with the inner cavity 1a.
[0038] In this embodiment of the invention, the noise-insulating block is a cubic structure composed of six noise-insulating plates 11 made of noise-insulating material. Its inner cavity 1a is a cubic cavity structure defined by the inner walls of the six noise-insulating plates 11. By sequentially stacking multiple blocks 1, adjacent blocks 1 are joined together by the outer walls of the noise-insulating plates 11 and fixedly connected using common building adhesives such as cement, a soundproof wall structure m can be formed. Each block 1 has a circular through-hole 111 at the center of its six noise-insulating plates 11. The entire block 1 forms a phonon crystal structure. When sound waves enter the inner cavity 1a through the circular through-holes 111, they undergo intense compression and expansion, thereby dissipating sound energy and creating a band gap. By adjusting the side length and thickness of the noise-insulating plates 11 to customize the specifications of the inner cavity 1a, noise insulation effects can be achieved for sound waves within a specific frequency range. Meanwhile, the circular through holes 111 on the noise insulation panel 11 can also enable communication between the two sides of the wall m, as well as between the pairs of multiple blocks 1. When designing its size, it can also be adjusted according to the noise frequency of the sound source and the needs of ventilation and heat dissipation to achieve the ventilation and heat dissipation effect. When assembling the wall m, it can be built in a fully enclosed manner around the sound source without the need for additional heat dissipation and smoke exhaust structures. It can balance its ventilation and heat dissipation capacity while ensuring the noise insulation effect, and greatly reduce the construction difficulty.
[0039] Optionally, the ratio of the thickness to the side length of the noise insulation plate 11 is 1 / 30, and the ratio of the radius of the circular through hole 111 to the side length of the noise insulation plate 11 is 1 / 12. Figure 4 This is the energy band diagram of the noise-insulating block provided in the embodiment of the present invention. Figure 5 This is a band gap diagram of the noise-insulating block provided in an embodiment of the present invention. For example... Figure 4 and Figure 5 As shown, exemplarily, in this embodiment of the invention, the side length a of the noise-insulating plate 11 is 36cm, its thickness d is 1.2cm, and the radius r of the circular through hole 111 on the noise-insulating plate 11 is 3cm. This block 1, with its specified dimensions, can provide strong noise isolation for noise waves in the frequency range of 0.2kHz to 1.3kHz. Further, as... Figure 5As shown, when the ratio of the thickness to the side length of the noise isolation plate 11 is fixed at 1 / 30, and the ratio of the radius of the circular through hole 111 to the side length of the noise isolation plate 11 is fixed at 1 / 12, the corresponding noise band frequency range will change accordingly by adjusting the side length 'a' of the noise isolation plate 11. The size of the block 1 can be adjusted according to the noise frequency of the sound source and the ventilation and heat dissipation requirements to achieve the ideal noise isolation effect.
[0040] Figure 6 This is a three-dimensional structural schematic diagram of another noise-insulating block provided in an embodiment of the present invention. For example... Figure 6 As shown, optionally, the six noise-insulating panels 11 include two opposing wall panels 11a and four splicing plates 11b disposed between the two wall panels 11a. At least one of the four splicing plates 11b is provided with a limiting protrusion 112, and at least one of the remaining three splicing plates 11b is provided with a limiting groove 113 that matches the limiting protrusion 112. Exemplarily, in this embodiment of the invention, the outer surfaces of two opposing noise-insulating panels 11 on the block 1 serve as wall panels 11a. After the wall m is glued and fixed to form a soundproof wall, the two wall panels 11a respectively form the opposite side walls of the wall m. The remaining four noise-insulating panels 11 located between the two wall panels 11a serve as splicing plates 11b that are glued together when they are spliced together. By setting corresponding limiting protrusions 112 and limiting grooves 113 on the splicing plate 11b, when splicing the splicing plates 11b together, the limiting protrusions 112 and limiting grooves 113 can be interlocked to achieve pre-limiting fixation between adjacent blocks 1 in the wall direction of the wall m, so that relative sliding occurs during the splicing and bonding process, thereby improving the stability and accuracy of the assembly.
[0041] Optionally, the limiting protrusion 112 is in the shape of an arcuate strip. For example, in this embodiment of the invention, both the limiting protrusion 112 and the corresponding limiting groove 113 are semi-cylindrical structures in the shape of an arcuate strip, which makes the assembly smoother and avoids collisions, improves the smoothness of assembly, and avoids damage.
[0042] Optionally, two limiting protrusions 112 are provided, symmetrically arranged on both sides of the circular through hole 111. Exemplarily, in this embodiment of the invention, on the assembly plate 11b with the limiting protrusions 112, two limiting protrusions 112 are symmetrically arranged on both sides of the circular through hole 111, and two matching limiting grooves 113 are provided on the corresponding assembly plate 11b. When assembling multiple blocks 1, the two sets of limiting protrusions 112 and limiting grooves 113 are used for fitting and limiting, avoiding excessive stress concentration and wear caused by a single set of limiting, further improving the assembly stability and overall service life of the noise-insulating blocks.
[0043] For example, in this embodiment of the invention, four splicing plates 11b are arranged in two groups of two opposite splicing plates 11b to form two sets. One set is provided with limiting protrusions 112, and the other set is provided with limiting grooves 113. In other possible implementations, other numbers and arrangements of limiting protrusions 112 and limiting grooves 113 may also be used, and this embodiment of the invention does not limit them.
[0044] Optionally, block 1 is a foam ceramic structural component. Exemplarily, in this embodiment of the invention, the foam ceramic block 1 has a lower density than traditional concrete brick blocks, approximately 800-900 kg / m³. Simultaneously, due to the large-volume cavities within this sound-insulating material, the overall weight of the block can be significantly reduced. The overall weight is approximately 1 / 18th that of a concrete brick block of the same volume, further reducing construction difficulty.
[0045] Figure 7 This is a structural schematic diagram of a soundproof wall provided in an embodiment of the present invention. Figure 7 As shown, embodiments of the present invention also provide a soundproof wall, including multiple such... Figures 1 to 6 The noise-insulating blocks shown are constructed by assembling and fixing multiple blocks 1 together with noise-insulating plates 11. Circular through-holes 111 on adjacent noise-insulating plates 11 are coaxially connected to form a wall m. Exemplarily, in this embodiment, by sequentially stacking multiple blocks 1, with adjacent blocks 1 joined together by the outer walls of the noise-insulating plates 11 and fixedly connected using common building adhesives such as cement, a soundproof wall structure m can be formed. This structure is simple and easy to construct. Each block 1 has a circular through-hole 111 at the center of its six noise-insulating plates 11. The entire block 1 forms a phononic crystal structure. When sound waves enter the inner cavity 1a through the circular through-holes 111, they undergo intense compression and expansion, thereby dissipating sound energy and creating a band gap. By adjusting the side length and thickness of the noise-insulating plates 11 to customize the specifications of the inner cavity 1a, noise insulation can be achieved for sound waves within a specific frequency range. Meanwhile, the circular through holes 111 on the noise insulation panel 11 can also enable communication between the two sides of the wall m, as well as between the pairs of multiple blocks 1. When designing its size, it can also be adjusted according to the noise frequency of the sound source and the needs of ventilation and heat dissipation to achieve the ventilation and heat dissipation effect. When assembling the wall m, it can be built in a fully enclosed manner around the sound source without the need for additional heat dissipation and smoke exhaust structures. It can balance its ventilation and heat dissipation capacity while ensuring the noise insulation effect, and greatly reduce the construction difficulty.
[0046] Figure 8 This is a schematic diagram of another soundproof wall structure provided in an embodiment of the present invention. Figure 8As shown, optionally, the soundproof wall includes multiple parallel wall sections m, where the side lengths of the blocks 1 within the multiple wall sections m are different. Exemplarily, in this embodiment of the invention, when cost and construction scope permit, multiple wall sections m can be formed by selecting blocks 1 with different side lengths. For example, two parallel wall sections m can be formed using blocks 1 with side length a of 36cm and those with side length a of 18cm. Using two layers of wall sections m for noise insulation allows the band gaps of blocks 1 with different noise insulation effects to overlap, broadening the frequency band of noise waves that can be isolated and further improving the noise insulation effect.
[0047] Figure 9 This is a flowchart of an assembly method provided by an embodiment of the present invention. Figure 9 As shown, embodiments of the present invention also provide an assembly method, applicable to, for example... Figure 7 The soundproof wall shown is assembled using the following method:
[0048] S1. Select a block 1 with the corresponding side length, thickness and radius of the circular through hole 111 according to the noise frequency.
[0049] S2. Multiple noise-insulating blocks 1 are joined together and fixedly connected by noise-insulating plates 11, so that the circular through holes 111 on two adjacent noise-insulating plates 11 are coaxially connected to form a wall m.
[0050] The soundproof wall formed using this assembly method has circular through holes 111 at the center of each of its six noise-insulating plates 11. The entire block 1 forms a phonon crystal structure. When sound waves enter the inner cavity 1a through the circular through holes 111, they undergo intense compression and expansion, thereby dissipating sound energy and creating a band gap. By adjusting the side length and thickness of the noise-insulating plates 11 to customize the specifications of the inner cavity 1a, noise insulation can be achieved for sound waves within a specific frequency range. Simultaneously, the circular through holes 111 on the noise-insulating plates 11 allow for communication between the two sides of the wall m, as well as between any two blocks 1. Their size can be adjusted according to the noise frequency of the sound source and the ventilation and heat dissipation requirements to achieve optimal ventilation and heat dissipation. When assembling the wall m, a fully enclosed structure can be built directly around the sound source without the need for additional heat dissipation and smoke extraction structures. This balances noise insulation with ventilation and heat dissipation capabilities, significantly reducing construction difficulty.
