They are widely used in noise-sensitive areas such as roads, highways, railways, industrial parks, etc. Sound barriers achieve the effect of noise reduction by building a physical barrier between the noise source and the protected area to reduce the propagation of sound waves. Common sound barriers are generally composed of supporting structures and sound-absorbing panels, and their special structural design achieves the function of blocking and absorbing sound waves.

[0003] In the prior art, for example, the Chinese utility model patent with publication number CN206359907U, entitled "A Sound Barrier Structure," was published on July 28, 2017. The invention uses a combination of unequal-sided H-shaped columns and a sound-absorbing barrier, wherein angle steel is fixed to the web by bolts, and one end of the sound-absorbing barrier is fixed by the other side of the angle steel and the long flange.

[0004] However, during actual installation, the inventors discovered that, due to the lack of a fixed structure between the angle steel and the sound-absorbing barrier, the upper sound-absorbing barrier could slip during the removal of the lower sound-absorbing barrier. Therefore, there is an urgent need for a sound barrier structure with an improved, removable screen that can achieve faster locking and release, thereby improving installation and maintenance efficiency.

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] like Figures 1 to 8 The detachable sound barrier structure shown includes:

[0034] At least two columns 1 are provided. Each column 1 includes a base 11 and a fixing plate 12 perpendicular to the base 11. The fixing plate 12 is provided with a plurality of fixing holes 13. It should be noted that the columns 1 can have an I-shaped cross section, an H-shaped cross section, a T-shaped cross section, or an L-shaped cross section. The specific structural form is determined by those skilled in the art. It should also be noted that the position of the fixing holes 13 is determined based on actual installation requirements.

[0035] A plurality of barrier panels 2 are provided between the two columns 1. The barrier panels 2 are provided with a plurality of mounting holes 21 that are positioned opposite to the plurality of fixing holes 13. It should be noted that the barrier panels 2 are installed side by side and can have a variety of shapes, including flat plates, folding plates, transparent plates, or shutters.

[0036] Several locking mechanisms 3 are provided. The locking mechanisms 3 extend into the mounting holes 21 and the fixing holes 13 and are configured to secure the barrier panels 2 to the columns 1. It should be noted that the locking mechanisms 3 can be implemented in a variety of ways, including bolt 31 locking, quick latch locking, and spring clip locking.

[0037] like Figure 1As shown, during the specific installation and use of the utility model, during installation, the barrier panel 2 is placed between the two columns 1, and the column 1 and the barrier panel 2 are locked by the locking mechanism 3; when one barrier panel 2 is damaged and needs to be replaced, it is only necessary to open the locking mechanism 3 on this barrier panel 2, take out one end of the barrier panel 2 first, tilt the barrier panel 2, and then move the other end out. When replacing a new barrier panel 2, one end of the new barrier panel 2 is tilted and inserted into the column 1, and then the other end of the barrier panel 2 is inserted into another column 1, and the new barrier panel 2 is locked by the locking mechanism 3 to complete the replacement and installation.

[0038] The detachable sound barrier structure of the present invention uses a locking mechanism 3 to keep the barrier plate 2 stable during the installation and disassembly process, avoiding the risk of the upper barrier plate 2 sliding when the lower barrier plate 2 is removed, thereby improving the safety of operation. The installation and disassembly of the structure are more convenient, which improves construction efficiency and is convenient for replacing or adjusting the plate during maintenance, reducing maintenance time.

[0039] like Figure 2 As shown, the column 1 also includes a reinforcing plate 14 arranged parallel to the fixing plate 12, and a middle plate 15 fixedly connected between the fixing plate 12 and the reinforcing plate 14. By providing the reinforcing plate 14 parallel to the fixing plate 12 in the column 1 and adding the middle plate 15 between the fixing plate 12 and the reinforcing plate 14, the present invention effectively enhances the structural strength and stability of the column 1. The design of the reinforcing plate 14 enables the column 1 to better withstand external pressures such as wind loads and vibrations. Furthermore, the sandwich structure formed by the middle plate 15 between the fixing plate 12 and the reinforcing plate 14 further improves the column 1's resistance to bending and compression.

[0040] like Figure 2 As shown, the column 1 has an I-shaped cross-section, and the reinforcement plate 14 is shorter than the fixed plate 12. The I-shaped cross-section of the column 1, along with the shorter reinforcement plate 14 than the fixed plate 12, results in excellent mechanical properties and structural stability. The I-shaped cross-section effectively disperses and withstands forces from all directions, enhancing bending strength and compressive resistance while reducing material usage and improving overall structural rigidity. The shorter reinforcement plate 14 than the fixed plate 12 provides greater space for installation of the locking mechanism 3.

[0041] like Figure 6 As shown, the distance between the reinforcing plate 14 and the fixing plate 12 is greater than the thickness of the barrier plate 2. The distance between the reinforcing plate 14 and the fixing plate 12 is greater than the thickness of the barrier plate 2, which effectively increases the installation space and stability of the barrier plate 2, ensures that the barrier plate 2 can be smoothly embedded without being restricted by excessive tightening, and provides installation space for the barrier plate 2 to be tilted in and out, thereby improving the convenience of operation.

[0042] like Figure 3 、 Figure 6 As shown, the end of the barrier plate 2 connected to the column 1 has two extensions 22, which are connected parallel to the two surfaces of the barrier plate 2. The installation holes 21 are opened on the extensions 22. First, the design of the extensions 22 reduces the thickness of the barrier plate 2, shortening the distance passed during the connection process and reducing installation time.

[0043] Continue as Figure 6 As shown, a receiving space is provided between the end of the extension 22 and the middle plate 15. This receiving space provides greater flexibility for the installation, positioning, and removal of the barrier plate 2, avoiding assembly difficulties caused by dimensional errors during installation and improving installation efficiency. The provision of the receiving space also provides space for the barrier plate 2 to move during removal and replacement.

[0044] like Figure 4 、 Figure 5 As shown, the connection between the two barrier panels 2 also has a sealing assembly 23, including a first sealing groove 23a provided on a side relatively close to the base 11, and a second sealing groove 23b provided on a side relatively far from the base 11. The space of the second sealing groove 23b is smaller than the space of the first sealing groove 23a, and the first sealing groove 23a has a sealing member 23c. The sealing assembly 23 effectively enhances the sealing performance of the connection between the barrier panels 2, prevents the infiltration of air, dust and moisture, and adapts to the complex outdoor environment; at the same time, the sealing assembly 23 reduces the leakage of sound waves in the gap and improves the noise reduction effect. The sealing member 23c acts as a buffer at the connection, reduces vibration wear and noise, and enhances seismic durability. The tighter structural design also reduces wind resistance, allowing the barrier panels 2 to remain stable in high wind speed environments. It should be pointed out here that the sealing member 23c can be in many forms, which can be a sealing strip, an O-ring, or a sealing ring of other shapes.

[0045] In some embodiments of the present invention, Figure 7 As shown, the locking mechanism 3 includes a bolt 31 and a nut 32. The bolt 31 passes through the installation through-hole 21 and the fixing through-hole 13, and the nut 32 is fixed and locked to the bolt 31. The locking mechanism 3 passes through the installation through-hole 21 and the fixing through-hole 13 by the bolt 31, and is then fixed and locked by the nut 32, thereby achieving a stable and reliable connection, and can firmly fix the barrier plate 2 and the column 1 together, ensuring the stability of the structure in high wind pressure or frequent vibration environments. The material of the bolt 31 and the nut 32 has good corrosion resistance and aging resistance, adapts to various harsh outdoor conditions, and extends the service life of the sound barrier. The matching mode of the bolt 31 and the nut 32 makes installation and disassembly convenient, facilitates subsequent maintenance and replacement, and improves maintenance efficiency.

[0046] In some embodiments of the present invention, Figure 8As shown, the locking mechanism 3 includes a screw 33 with a protruding straight-shaped locking pin 33a at the end of the screw 33. The mounting through-hole 21 and the fixing through-hole 13 have the same shape as the locking pin's cross-section. The end surface of the fixing plate 12 away from the barrier plate 2 has a locking groove 33b. When the straight-shaped locking pin 33a extends out of the fixing through-hole 13, the screw 33 is rotated, causing the straight-shaped locking pin 33a to slide into the locking groove 33b. When the straight-shaped locking pin 33a extends out of the fixing through-hole 13, the screw 33 is rotated, causing the locking pin to slide into the locking groove 33b at the end of the fixing plate 12. The locking mechanism 3 is locked by the cooperation between the straight-shaped locking pin 33a and the locking groove 33b. The locking mechanism 3 can be quickly installed and locked without the need for additional tools, making it easy to operate and effectively improving the efficiency of installation and removal.

[0047] In some embodiments of the present invention, a spring is further provided between the screw 33 and the fixing plate 12, with one end of the spring abutting against the fixing plate 12 and the other end abutting against the screw 33. The spring provides a preload during the locking process, ensuring that the screw 33 maintains close contact after installation, preventing loosening due to vibration or external forces, and further improving the stability and durability of the structure. The buffering effect of the spring also reduces direct friction and wear between the screw 33 and the fixing plate 12, extending the service life of the assembly and improving the adaptability of the sound barrier structure in high wind pressure or vibration environments.

The above-described embodiments and the specification are merely illustrative of the principles of the present invention.
