[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0023] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The utility model embodiment provides a snap-on non-metallic roadbed sound barrier, such as Figure 1-5 As shown, the snap-on non-metallic roadbed sound barrier comprises: a plurality of H-shaped columns 1, a plurality of non-metallic sound insulation boards 2 for preventing the propagation of sound waves are arranged between the plurality of H-shaped columns 1; a plurality of bottom plates 4 are respectively arranged at the bottom of the plurality of H-shaped columns 1; a plurality of shells 5 are respectively welded to the top of the plurality of bottom plates 4; a plurality of buffer mechanisms are respectively installed on the plurality of shells 5 for anti-collision; and a protective mechanism is assembled on the plurality of H-shaped columns 1 for protecting the non-metallic sound insulation boards 2.

[0025] It should be noted that the structure of the existing non-metallic sound barrier is generally composed of a column with an H-shaped cross-section and a number of vertically stacked non-metallic sound insulation panels directly inserted into two adjacent columns. When the non-metallic sound barrier is in use, it lacks the corresponding anti-impact buffering function. When it is accidentally collided with a vehicle, it will cause great damage to the non-metallic sound barrier and the vehicle, which will increase the cost of subsequent maintenance.

[0026] In the scheme, when in use, first use multiple bolts to fix multiple base plates 4 and multiple H-shaped columns 1 on the ground, then insert multiple non-metallic sound insulation panels 2 between two adjacent H-shaped columns 1, and after the multiple non-metallic sound insulation panels 2 are installed, the protective mechanism is installed. After the installation is completed, the clip-on non-metallic roadbed sound barrier can be put into use. If it is hit by a vehicle during use, the protective mechanism will first contact the vehicle to prevent the vehicle from hitting the non-metallic sound insulation panel 2, and the non-metallic sound insulation panel 2 is shielded and protected. The impact force received by the protective mechanism will be directly transmitted to the H-shaped column 1. After the H-shaped column 1 is hit, it will move closer to the shell 5, so that the impact force can be transmitted to the buffer mechanism, and the buffer mechanism will weaken the impact force. In this way, the damage to the clip-on non-metallic roadbed sound barrier and the vehicle can be minimized, which is conducive to reducing the cost of subsequent maintenance and has a good use effect.

[0027] In a further preferred embodiment of the utility model, the buffer mechanism includes: a plurality of support columns 6 slidably mounted on the shell 5, one end of each of the plurality of support columns 6 is fixedly connected to the H-shaped column 1; a pressure plate 7 welded to the plurality of support columns 6; a limiting rod 8 fixedly mounted on the inner walls on both sides of the shell 5; a plurality of damping blocks 9 slidably mounted on the limiting rod 8 for weakening the impact force; a plurality of springs 10 slidably mounted on the limiting rod 8; a plurality of sliders 11 slidably mounted on the limiting rod 8, one side of each of the two sliders 11 is hinged with a hinged rod 12, and one end of each of the plurality of hinged rods 12 is hinged to one side of the pressure plate 7.

[0028] In this embodiment, the buffer mechanism is used to weaken the impact force received by the clip-on non-metallic roadbed sound barrier when it collides with a vehicle. The impact force received by the H-shaped column 1 will be transmitted to the support column 6, causing the support column 6 to slide on the shell 5, and causing the support column 6 to drive the pressure plate 7 to move to one side. The movement of the pressure plate 7 will drive the hinged rod 12 to rotate, causing the hinged rod 12 to drive the slider 11 to slide on the limit rod 8. The sliding of the slider 11 will squeeze the spring 10, and finally the pressure received by the spring 10 will be absorbed and weakened by the damping block 9, thereby weakening the impact force received by the clip-on non-metallic roadbed sound barrier when it collides with a vehicle.

[0029] In a further preferred embodiment of the utility model, the protective mechanism includes: a plurality of sleeves 13 respectively welded on the plurality of H-shaped columns 1, a same support rod 14 being slidably mounted on the plurality of sleeves 13, a plurality of rotating shafts being fixedly mounted on the support rod 14; and a plurality of anti-collision columns 15 respectively rotatably mounted on the plurality of rotating shafts.

[0030] In this embodiment, the protective mechanism is used to protect the non-metallic sound insulation board 2. During installation, the support rod 14 is inserted into the two sleeves 13. After installation, when the snap-on non-metallic roadbed sound barrier is hit by a vehicle, the anti-collision column 15 will first contact the vehicle. If it is only a slight scratch, the anti-collision column 15 will rotate on the rotating shaft. The rotation of the anti-collision column 15 can reduce the wear and tear of the vehicle and reduce the damage to the snap-on non-metallic roadbed sound barrier. When the scratch is light, the damage can be ignored, and the use effect is better.

[0031] In a further preferred embodiment of the present invention, the plurality of base plates 4 are all configured to be rectangular, and the plurality of base plates 4 are provided with a plurality of fixing holes 16 for installing bolts.

[0032] In this embodiment, the provision of multiple fixing holes 16 can facilitate manual fixing of the snap-on non-metallic roadbed sound barrier to the ground using multiple bolts.

[0033] In a further preferred embodiment of the utility model, the plurality of non-metallic sound insulation panels 2 are each provided with a plurality of slots, and the plurality of H-shaped columns 1 are each fixedly mounted with a plurality of elastic rubber strips 3, and the plurality of elastic rubber strips 3 are respectively adapted to the plurality of slots.

[0034] In this embodiment, the arrangement of the card slot and the elastic rubber strip 3 can make the installation between the H-shaped column 1 and the non-metallic sound insulation board 2 more stable.

[0035] In a further preferred embodiment of the present invention, the plurality of springs 10 are all made of stainless steel, and one side of the plurality of springs 10 is fixedly connected to one side of the plurality of sliders 11 respectively.

[0036] In this embodiment, the spring 10 made of stainless steel will not be corroded and has a longer service life.

[0037] In a further preferred embodiment of the present invention, the plurality of anti-collision columns 15 are all made of rubber, the support rod 14 is configured to be U-shaped, and the plurality of sleeves 13 are all configured to be rectangular.

[0038] In this embodiment, the anti-collision column 15 made of rubber can reduce the damage to the vehicle when it is scratched, and can play a good protective role.

[0039] In a further preferred embodiment of the present invention, a plurality of reflective tapes are fixedly mounted on the plurality of anti-collision columns 15, and the plurality of reflective tapes are used to warn vehicles traveling at night.

[0040] In this embodiment, the reflective tape can serve as a good warning and reminder to the drivers in the vehicles at night, and can reduce the probability of the vehicles colliding with the snap-on non-metallic roadbed sound barrier.

[0041] Compared with the related art, in the present solution, multiple fixing holes 16 can be used to conveniently fix the clip-on non-metallic roadbed sound barrier to the ground manually using multiple bolts. Multiple elastic rubber strips 3 can stably insert multiple non-metallic sound insulation panels 2 between two adjacent H-shaped columns 1, and the installation effect is good. The buffer mechanism can minimize the damage to the clip-on non-metallic roadbed sound barrier when it collides with the vehicle, and can weaken the impact force, which is beneficial to reduce the cost of subsequent maintenance. The use effect is good. The protective mechanism can prevent the vehicle from colliding with the non-metallic sound insulation panel 2, which has a good protective effect on the non-metallic sound insulation panel 2, and can also reduce the damage to the vehicle when it rubs against the clip-on non-metallic roadbed sound barrier. The reflective tape can play a good warning and reminder role for the driver in the vehicle at night, which can reduce the probability of the vehicle colliding with the clip-on non-metallic roadbed sound barrier.
