Description

Technical Field

[0001] This utility model relates to the field of sound barrier technology, specifically a basalt fiberboard sound barrier. Background Technology

[0002] Sound barriers are effective facilities for reducing noise pollution from traffic, industry, and other sources. They typically consist of three parts: a sound-absorbing layer, a sound-insulating layer, and supporting components. The sound-absorbing layer often uses porous materials such as glass wool or rock wool, where sound waves penetrate the material and dissipate energy through friction. The sound-insulating layer commonly uses metal plates, transparent PC boards, or concrete boards to reflect sound waves and prevent them from penetrating. The supporting structure uses steel columns or concrete foundations to fix the barrier's position. Its core function is to significantly reduce the impact of noise on the surrounding environment by blocking and absorbing energy along the sound wave's propagation path.

[0003] Existing sound barriers typically consist of sound-absorbing and sound-insulating layers fabricated into barrier panels, which are then installed onto a supporting structure to complete the overall structural installation. However, installing the barrier panels usually requires lifting each panel from above and placing it into a slot in the supporting structure, which is difficult and inefficient due to the frequent lifting and lowering of the panels. Alternatively, each barrier panel can be pre-positioned and fixed to the supporting structure using bolts or other connectors, but this method is cumbersome, time-consuming, and hinders efficient disassembly. Therefore, to address these issues, a basalt fiberboard sound barrier is proposed. Utility Model Content

[0004] To address the technical problems of existing sound barriers, such as high installation difficulty and low installation efficiency, cumbersome and time-consuming operation, and difficulties in efficient subsequent disassembly, this utility model provides a basalt fiberboard sound barrier.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] A basalt fiberboard sound barrier includes a concrete base beam on which support columns arranged in an array are fixedly mounted. The support columns have an I-shaped cross-section and slots formed on both sides. A bottom sealing plate is mounted on the concrete base beam and located between the support columns. The barrier body is composed of several fiber partitions spliced ​​from top to bottom. Each fiber partition includes a main body, and several mounting blocks with dimensions matching the slots are fixedly mounted at both ends. Several sets of mounting slots corresponding to the mounting blocks are opened on both sides of the back of the support columns. After the bottom fiber partition overlaps with the bottom sealing plate, all the mounting blocks are offset from the mounting slots.

[0007] In one possible implementation, the main body of the plate is made by adding basalt fiber to melted resin, stretching it through an extruder, and then cutting it. A splicing groove is formed at the upper end, and a splicing head that matches the size of the splicing groove is fixedly provided at the lower end.

[0008] In one possible implementation, the plate body has a plurality of vertically arranged and arrayed weight-reducing grooves, and the inner wall of the weight-reducing grooves is fixedly provided with a plurality of symmetrically arranged reinforcing ridges.

[0009] In one possible implementation, the main body of the board has several through sound-absorbing grooves, and the sound-absorbing grooves correspond one-to-one with the weight-reducing vertical grooves. A sound-absorbing core made of porous sound-absorbing material is inserted into the weight-reducing vertical groove.

[0010] In one possible implementation, a reinforcing plate is bolted to one side of the support column where the mounting groove is provided. Several snap-fit ​​plates corresponding to the mounting groove are fixedly provided on the reinforcing plate. After the reinforcing plate is bolted to the support column, the snap-fit ​​plates are snapped into the mounting groove.

[0011] In one possible implementation, a mounting plate is fixedly provided on the top of the support column, and an upper cover plate is provided on the top of the support column. The upper cover plate includes a cover plate body with connecting ears fixedly connected to both ends. The bottom end of the cover plate body is inserted into the splicing groove of the topmost fiber partition, and the connecting ears are bolted to the mounting plate.

[0012] In one possible implementation, a column end plate is fixedly provided at the bottom of the support column, and a plurality of bent anchor bars arranged in a circular array are fixedly provided on the lower end surface of the column end plate, which are anchored into the concrete bottom beam.

[0013] In one possible implementation, the upper surface of the bottom sealing plate is provided with a receiving groove whose size matches the size of the splicing head.

[0014] In summary, this utility model has the following beneficial technical effects:

[0015] When installing the fiber partition between the support columns, align the mounting clips on both sides of the fiber partition with the mounting grooves on the support columns, and then push the entire fiber partition between the support columns. Under the action of gravity, the fiber partition will slide down a certain distance, causing the mounting clips and mounting grooves to misalign. At this point, the entire fiber partition cannot be removed. After the fiber partitions are inserted one by one from bottom to top, the stability of the overall structure can be ensured under its own weight. The above installation method does not require lifting and lowering each fiber partition, nor does it require fixing with multiple sets of connectors. It can ensure that the installation and subsequent disassembly of the entire sound barrier structure are simple and easy, significantly improving the efficiency of installation and disassembly.

[0016] For fiber partitions, since the main body of the board can be spliced ​​together by the cooperation of the splicing head and splicing groove, several fiber partitions can be spliced ​​together to form a stable whole after installation, which has strong structural stability and can also avoid the existence of splicing gaps that would affect the sound insulation effect of the overall structure.

[0025] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0026] like Figure 1 - Figure 3As shown, this embodiment provides a basalt fiberboard sound barrier, including a concrete base beam 1 on which support columns 2 are fixedly arranged in an array. The support columns 2 have an I-shaped cross-section and slots on both sides. A bottom sealing plate 3 is set on the concrete base beam 1 and located between the support columns 2. The barrier body is composed of several fiber partitions 4 spliced ​​from top to bottom. The fiber partition 4 includes a plate body 41, and several mounting blocks 42 with the same size as the slots are fixedly set at both ends. Several sets of mounting grooves 21 corresponding to the mounting blocks 42 are opened on both sides of the back of the support columns 2. After the bottom fiber partition 4 overlaps with the bottom sealing plate 3, all the mounting blocks 42 are staggered with the mounting grooves 21.

[0027] Based on the above structural scheme, when the mounting blocks 42 on both sides of the fiber partition 4 are aligned with the mounting grooves 21 on the support column 2, the fiber partition 4 can be pushed into the support column 2 as a whole. Then, under the action of gravity, the fiber partition 4 will slide down a certain distance until it overlaps with the bottom sealing plate 3. At this time, the mounting blocks 42 and the mounting grooves 21 are misaligned, so that the fiber partition 4 cannot slide out as a whole. Then, the fiber partitions 4 are inserted from bottom to top. Under the action of the weight of the fiber partition 4 itself, the stability of the overall structure can be ensured. The above installation method does not require lifting and lowering each fiber partition 4, nor does it require fixing with multiple sets of connectors. It can ensure that the installation and subsequent disassembly of the entire sound barrier structure are simple and easy, and significantly improve the installation and disassembly efficiency.

[0028] The main body 41 is made of basalt fiber added to melted resin, stretched and cut by an extruder. Based on the process of making natural basalt by high-temperature melting and drawing, its internal porous structure gives it excellent sound absorption performance, which can effectively absorb and consume sound wave energy. It has a significant sound insulation effect, especially in the mid-to-high frequency range such as human voice and equipment noise. The material has low density, strong damping, and is both environmentally friendly and long-lasting. It does not release harmful substances and has a long service life.

[0029] like Figure 4 As shown, the upper end of the board body 41 is machined with a splicing groove 43, and the lower end is fixed with a splicing head 44 that matches the size of the splicing groove 43. Since the board bodies 41 can be spliced ​​together by the cooperation of the splicing head 44 and the splicing groove 43, several fiber partitions 4 can be spliced ​​together to form a stable whole after installation, which has strong structural stability and can also avoid the existence of splicing gaps that affect the sound insulation effect of the overall structure.

[0030] To reduce the overall weight of the main body 41 and thus facilitate installation, such as Figure 4As shown, the main body 41 of the board has several vertically arranged and arrayed weight-reducing grooves. The inner wall of the weight-reducing grooves is fixed with several symmetrically arranged reinforcing ridges. The reinforcing ridges can compensate for the weakening of the overall strength of the main body 41 due to the opening of the weight-reducing grooves to a certain extent. At the same time, the main body 41 of the board has several through sound-absorbing grooves 45, and the sound-absorbing grooves 45 correspond one-to-one with the weight-reducing grooves. A sound-absorbing core 46 made of porous sound-absorbing material is inserted into the weight-reducing grooves. The combination of the sound-absorbing grooves 45 and the sound-absorbing core 46 can achieve multiple sound absorption and noise reduction effects, further enhancing the overall sound absorption and sound insulation effect of the main body 41 of the board.

[0031] like Figure 5 As shown, a reinforcing plate 6 is bolted to one side of the support column 2 where the mounting groove 21 is provided. Several snap-fit ​​plates 61 corresponding to the mounting groove 21 are fixedly provided on the reinforcing plate 6. After the reinforcing plate 6 is bolted to the support column 2, the snap-fit ​​plates 61 are snapped into the mounting groove 21. When there is a high requirement for the overall strength and structural stability of the support column 2, that is, when the sound barrier is set up in a harsh environment, the support column 2 can be reinforced by installing the reinforcing plate 6 to avoid insufficient overall strength of the support column 2 due to the opening of the mounting groove 21.

[0032] like Figure 5 As shown, a mounting plate 22 is fixedly installed on the top of the support column 2, and an upper cover plate 5 is installed on the top of the support column 2. The upper cover plate 5 includes a cover plate body 51, and connecting ears 52 are fixedly connected to both ends. The bottom end of the cover plate body 51 is inserted into the splicing groove 43 of the topmost fiber partition 4. The connecting ears 52 are bolted to the mounting plate 22. The above structure can complete the overall fixed installation of the upper cover plate 5. At the same time, the fixed connection between the upper cover plate 5 and the support column 2 can play a pressing role on the topmost fiber partition 4, thereby completing the limiting and fixing of all fiber partitions 4 and further improving the stability of the overall structure.

[0033] like Figure 6 As shown, a column end plate 23 is fixedly installed at the bottom of the support column 2. Several bent anchor bars 24 arranged in a circular array are fixedly installed on the lower end face of the column end plate 23. They are anchored into the concrete bottom beam 1. The setting of the bent anchor bars 24 can ensure that the support column 2 can be firmly connected to the concrete bottom beam 1 after the concrete bottom beam 1 is poured, thereby ensuring that the support column 2 has a strong load-bearing capacity and high stability.

[0034] like Figure 6 As shown, the upper surface of the bottom sealing plate 3 is provided with a receiving groove 31, the size of which matches the size of the splicing head 44. The opening of the receiving groove 31 can play a role in positioning and fixing the bottom fiber partition 4 through snap-fit ​​connection, which is conducive to improving the stability of the overall structure.

[0035] The working principle and usage process of this utility model:

[0036] During installation, align the mounting blocks 42 on both sides of the fiber partition 4 with the mounting grooves 21 on the support columns 2, and push the fiber partition 4 into the support columns 2. Then, under the action of gravity, the fiber partition 4 will slide down a certain distance until it overlaps with the bottom sealing plate 3. At this time, the mounting blocks 42 and the mounting grooves 21 are misaligned, so that the fiber partition 4 cannot slide out. Then, the fiber partitions 4 are inserted one by one from bottom to top. Under the action of the weight of the fiber partitions 4 themselves, the stability of the overall structure can be ensured. The above installation method does not require lifting and lowering each fiber partition 4, nor does it require fixing with multiple sets of connectors. It can ensure that the installation and subsequent disassembly of the entire sound barrier structure are simple and easy, and significantly improve the installation and disassembly efficiency.

[0037] Furthermore, during the sequential installation of the fiber partitions 4, they can be interlocked and spliced ​​together through the cooperation of the splicing head 44 and the splicing groove 43. Therefore, after the installation is completed, several fiber partitions 4 can be spliced ​​together to form a stable whole, which has strong structural stability and can also avoid the existence of splicing gaps that would affect the sound insulation effect of the overall structure.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
