Description

Technical Field

[0001] This utility model relates to the field of highway environmental protection facilities technology, and in particular to a sound barrier that is easy to disassemble and wind-resistant. Background Technology

[0002] In real-world production and daily life, sound barriers have a large surface area exposed to wind and poor lateral stability. This is especially true in windy areas, where sound barriers are frequently blown down by strong winds. During the winter snow season, snowplows quickly throw snow onto the roadside, and on sections with sound barriers, the cleared snow can severely damage or even topple the barriers. Existing sound barrier structures use a pull-out design where the sound-absorbing panels are embedded in grooves on the sides of the H-shaped steel columns. This makes them extremely vulnerable to being blown down or damaged during heavy snow or strong winds. Furthermore, installation, removal, and replacement require lifting each panel from the top of the column to remove it, which is time-consuming, labor-intensive, and inconvenient. Therefore, to address the above problems, a sound barrier that is easy to disassemble and wind-resistant is proposed to solve these problems. Utility Model Content

[0003] To address the problems existing in the prior art, a detachable windproof sound barrier is proposed.

[0004] The technical solution of this utility model to solve the technical problem is as follows: a detachable windproof sound barrier, comprising several columns fixed to the ground, with equal spacing between adjacent columns; each column is connected to at least one pair of mounting seats, the mounting seats of adjacent columns facing each other, and a horizontal bar connecting the two mounting seats. The horizontal bars are arranged vertically, and sound-absorbing panels are hung on the horizontal bars. The sound-absorbing panels can swing along the horizontal bars, and the sound-absorbing panels are arranged vertically in sequence to form a sound-absorbing barrier. The foundation of the H-shaped steel columns of the sound barrier is conventionally constructed, i.e., the columns are fixed to a concrete foundation with anchor bolts, which will not be elaborated here.

[0005] Preferably, the sound-absorbing panel is hung on the crossbar by a hoisting assembly; the hoisting assembly includes several hanging straps, which are fastened to the crossbar, and at least two second bolt holes are opened on the hanging straps; the two sides of the sound-absorbing panel are respectively attached to the hanging straps, and at least two first bolt holes are correspondingly opened on the hanging straps, and the fixing bolts pass through the first bolt holes on both sides, the second bolt holes on the hanging straps, and the sound-absorbing panel for fixing.

[0006] Preferably, the bottom of the sling is provided with a third bolt hole, and the fixing bolt passes through the third bolt holes on both sides and the sound-absorbing plate clamped by the two slings to strengthen the fixation of the sound-absorbing plate.

[0007] Preferably, the hanging strap has an inverted U-shaped structure, and the end of the arc-shaped inner wall of the hanging strap is concave to form a boss structure, which can clamp the sound-absorbing plate.

[0008] Preferably, the upper left corner of the mounting base has an opening that slopes downwards at a 45-degree angle to form a slide rail, extending to the lower U-shaped groove. The width of the groove is slightly larger than the outer diameter of the crossbar. The two ends of the crossbar are placed in the U-shaped grooves of the mounting bases of the adjacent columns. When installing the crossbar, it enters the U-shaped groove from the slide rail. The hook-shaped design of the inclined slide rail and the U-shaped groove effectively restricts the crossbar from falling off, while allowing the crossbar to rotate freely.

[0009] Preferably, a washer is also fitted on the crossbar to prevent the sound-absorbing panel from moving laterally, and the washer is placed in the gap between the end of the sound-absorbing panel and the mounting base.

[0010] Preferably, the columns are made of H-beam steel.

[0011] Preferably, the inner diameter of the arc-shaped inner wall of the strap is larger than the outer diameter of the crossbar, so that the strap can rotate freely on the crossbar.

[0012] Compared with existing technologies, the above technical solution has the following advantages or beneficial effects: 1. The sound-absorbing panel of this utility model can swing around the crossbar and can buffer the impact of wind by adjusting its own angle. When encountering strong winds, the sound-absorbing panel can buffer the impact of wind by swinging slightly, avoiding the wind force from directly acting on the overall structure and causing it to tip over; ensuring that the sound-absorbing panel is not easy to fall off or be damaged when hit by strong winds or snow.

[0013] 2. This utility model enables convenient disassembly and replacement of the sound-absorbing panel. The sound-absorbing panel is suspended on the crossbar by a hanging strap. During disassembly, simply unscrew the fixing bolts connecting the hanging strap and the crossbar to remove the sound-absorbing panel from the crossbar. Alternatively, the crossbar along with the sound-absorbing panel can be removed from the slide rail of the mounting base. There is no need for large-scale disassembly of the overall structure, nor is it necessary to use large equipment to lift the sound-absorbing panel to the top of the column. During installation, simply fasten the sound-absorbing panel to the crossbar using the hanging strap, and then use the fixing bolts to secure the hanging strap and the crossbar.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Example 1: Please see Figures 1-11 In this embodiment, the detachable windproof sound barrier consists of a base support structure composed of multiple columns 1. The columns 1 are firmly fixed to the concrete foundation using embedded parts or anchor bolts, with equal spacing between adjacent columns 1 to form a stable frame system. Each column 1 is connected to at least one pair of mounting seats 3 (each pair of mounting seats 3 is spaced apart along the height of the column 1), and the mounting seats 3 on adjacent columns 1 are arranged opposite each other. A horizontal crossbar 6 is connected between two opposing mounting seats 3, and multiple crossbars 6 are arranged parallel to each other along the height of the column 1, forming a multi-layered hanging structure. Sound-absorbing panels 2 are suspended from the crossbars 6 using a specific connection method, and the sound-absorbing panels 2 can swing freely around the crossbars 6. Multiple sound-absorbing panels 2 are arranged vertically and then spliced ​​together to form a complete sound-absorbing barrier. The ability of the sound-absorbing panels 2 to swing along the crossbars 6 allows them to adjust their angle to buffer wind impact, reduce damage from strong winds, and improve windproof performance. The evenly spaced columns 1 and the multi-layered crossbars 6 ensure overall structural stability and adapt to the length requirements of different sites.

[0028] Example 2: Continue reading Figures 1-11 Based on Embodiment 1, this embodiment further designs the connection between the sound-absorbing panel 2 and the crossbar 6. The sound-absorbing panel 2 is suspended on the crossbar 6 by a specially designed lifting assembly. This assembly includes several hanging straps 5, the top of which is hooked and fastened to the crossbar 6. The main body of the hanging strap 5 has at least two second bolt holes 10. A hanging strap 4 is attached to each of the front and back sides of the sound-absorbing panel 2. The two hanging straps 4 are attached to the sound-absorbing panel 2, which can distribute the pressure of the bolts on the sound-absorbing panel 2 and prevent the sound-absorbing panel 2 from being damaged due to excessive local stress. The hanging straps 4 can be made of steel plate, and at least two first bolt holes 9 are opened on the hanging straps 4 corresponding to the second bolt holes 10 of the hanging straps 5. During installation, the fixing bolts 7 pass through the first bolt holes 9 of the hanging straps 4 on one side, the sound-absorbing panel 2, the second bolt holes 10 of the hanging straps 5, and the first bolt holes 9 of the hanging straps 4 on the other side in sequence. The connection between the sound-absorbing panel 2 and the hanging straps 5 is achieved by tightening the nuts. The bolt connection method is easy to disassemble, and the damaged sound-absorbing panel 2 can be replaced separately, reducing maintenance costs.

[0029] In addition, to strengthen the fixation and prevent the sound-absorbing panel 2 from falling off, a third bolt hole is additionally opened at the bottom of the sling 4, which corresponds to the bottom of the sound-absorbing panel 2. When two adjacent sound-absorbing panels 2 are vertically spliced, the fixing bolt 7 passes through the third bolt hole of the sling 4 on both sides and the overlapping area of ​​the bottom of the two sound-absorbing panels 2, and is tightened by nuts, forming a secondary fixation for the bottom of the sound-absorbing panel 2.

[0030] In this embodiment, the hanging strap 5 has an overall inverted U-shaped structure, with its arc-shaped inner wall in contact with the crossbar 6. At the end of the arc-shaped inner wall (i.e., at the opening of the hanging strap 5), a protrusion 11 is formed by recessing inward. When the hanging strap 5 is fastened to the crossbar 6, the distance between the two protrusions 11 is slightly smaller than the outer diameter of the crossbar 6, and the sound-absorbing plate is clamped by the elastic clamping force of the protrusions 11.

[0031] Example 3: Continue reading Figures 1-11 In this embodiment, the upper left corner of the mounting base 3 opens at an angle of 45 degrees downward to form a slide 13, which extends to the lower U-shaped groove 12. The width of the groove 12 is slightly larger than the outer diameter of the crossbar 6. The two ends of the crossbar 6 are respectively placed in the U-shaped groove 12 of the mounting base 3 of the adjacent column 1. When installing the crossbar 6, it enters the U-shaped groove 12 from the slide 13. The hook-shaped design of the inclined slide 13 and the U-shaped groove 12 effectively restricts the crossbar 6 from falling off, while allowing the crossbar 6 to rotate freely. The mounting base 3 is welded to the column 1.

[0032] In addition, several washers 8 (made of rubber, plastic or metal) are fitted on the crossbar 6, and the outer diameter of the washers 8 is slightly larger than the thickness of the sound-absorbing panel 2. After the sound-absorbing panel 2 is suspended on the crossbar 6, the washers 8 are placed in the gap between the end of the sound-absorbing panel 2 and the mounting base. The gap is filled by the compression of the washers 8, which restricts the lateral movement of the sound-absorbing panel 2 along the axis of the crossbar 6.

[0033] Example 4: Based on the above embodiments, the column 1 in this embodiment is made of H-beam steel with an "H" shaped cross-section, having upper and lower flanges and a middle web, and is manufactured through welding or integral forming processes. The flange width and web thickness of the H-beam steel column 1 are designed according to the barrier height and wind resistance requirements to ensure that it has sufficient bending and shear strength.

[0034] Example 5: Please see Figure 11 Based on the above embodiments, in this embodiment, the inner diameter of the arc-shaped inner wall of the hanging strap 5 is slightly larger than the outer diameter of the crossbar 6, with a certain gap between them. When the sound-absorbing panel 2 is subjected to wind force, the hanging strap 5 can rotate freely around the crossbar 6, causing the sound-absorbing panel 2 to adjust its angle until it is parallel to the wind direction or forms a buffer angle. The free rotation design allows the sound-absorbing panel 2 to adaptively adjust with the wind direction, reducing the impact of wind load on the barrier and improving wind resistance; during the rotation process, the wind force can be dispersed, avoiding excessive local stress that could lead to structural damage, and enhancing the lateral stability of the sound barrier.

[0035] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
