At the same time, the splicing plates 202 and the splicing grooves 201 can be separated from each other to disassemble the plate-shaped sound barrier body 1 and the barrier splicing columns 3 by simply removing the connecting pieces 203. The assembly and disassembly methods of the plate-shaped sound barrier body 1 and the barrier splicing columns 3 are simple and easy to operate, which facilitates the rapid assembly of the plate-shaped sound barrier body 1 and the barrier splicing columns 3 for use at the installation site.
[0042] See also Figure 1-Figure 6As shown, a buffer protection component 5 for buffering and protecting the front part of the plate-shaped sound barrier body 1 when impacted is provided in front of the plate-shaped sound barrier body 1. Specifically, the buffer protection component 5 includes a matching hole 505, a base plate 503 and a connecting rod 509. Matching holes 505 are longitudinally opened in the middle of the matching seat 404, and the matching holes 505 are all through holes. The base plate 503 is located in front of the plate-shaped sound barrier body 1 and is parallel to the plate-shaped sound barrier body 1. At the same time, the front of the base plate 503 is covered with a buffer lining 502 fixed with a buffer material. Connecting rods 509 are longitudinally fixed to the four corners of the back of the base plate 503 through connecting sleeves 504. The connecting rods 509 are coaxially matched with the matching holes 505 one by one, and the connecting rods 509 longitudinally pass through the corresponding matching holes 505 in a coaxial sliding fit. The connecting rods 509 extend out of the rear end of the matching holes 505. The ends are coaxially fixed with end plates 507, and the outer periphery of the connecting rod 509 located between the corresponding end plates 507 and the matching seat 404 is coaxially fixed with buffer springs 506, and the two ends of the buffer springs 506 are fixedly connected to the corresponding end plates 507 and the matching seat 404. The purpose of this arrangement is to provide buffering protection capabilities for the rear plate-shaped sound insulation barrier body 1 through the arrangement of the buffer protection component 5. Specifically, the surface of the base plate 503 of the buffer protection component 5 is covered with a buffer lining 502 fixed with a buffer material, and then when it is accidentally impacted, the impact force can be initially buffered by the elastic deformation of the buffer lining 502. At the same time, the outer periphery of the connecting rod 509 of the buffer protection component 5 is coaxially arranged with a buffer spring 506, and then when it is accidentally impacted, the impact force can be secondarily buffered by the tensile deformation of the buffer spring 506.
[0043] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, both sides of the top and bottom surfaces of the plate-shaped noise barrier body 1 are installed with disassembly and assembly components 4, parts of the disassembly and assembly components 4 are respectively fixed to the corner positions corresponding to the back of the buffer protection component 5, and the buffer protection component 5 is detachably fixed to the front part of the plate-shaped noise barrier body 1 through the disassembly and assembly components 4. Specifically, the disassembly and assembly components 4 include a matching seat 404 and a fixing sleeve 403. The number of matching seats 404 is multiple and they are respectively installed at the corner positions corresponding to the back of the buffer protection component 5. The outer end surfaces of the matching seats 404 at the two sides that are away from each other are opened along the lateral direction. There are limited holes 406, and fixing sleeves 403 are fixedly installed on both sides of the top and bottom surfaces of the plate-shaped noise barrier body 1. Preferably, the bottom surface of the fixing sleeve 403 on the bottom surface of the plate-shaped noise barrier body 1 is higher than the bottom end of the barrier column body, and the fixing sleeves 403 are longitudinally provided with matching grooves 405, and the matching grooves 405 are all through grooves in the longitudinal direction, and the matching seats 404 correspond to the matching grooves 405 one by one and are longitudinally slidably matched, and the outer end surfaces of the fixing sleeves 403 at the two side positions that are away from each other are transversely provided with mounting holes 407, and the mounting holes 407 are vertically connected with the corresponding matching grooves 405, and the mounting holes 407 are all laterally coaxial with the corresponding limiting holes 406, the mounting holes 407 are all laterally coaxially slidably matched with the limiting rods 408, and the inner ends of the limiting rods 408 at the two sides that are close to each other are laterally slidably matched with the corresponding limiting holes 406, and the outer ends of the limiting rods 408 at the two sides that are far away from each other extend out of the outer end surface of the corresponding fixing sleeve 403 and are coaxially fixed with the handle 401, and the part of the limiting rod 408 located between the corresponding handle 401 and the outer end surface of the fixing sleeve 403 is coaxially gap-matched with the tension spring 402, and the two ends of the tension spring 402 are respectively connected to the corresponding handle 401 and the fixing sleeve 403. The outer end surface of the sleeve 403 is fixedly connected. The purpose of this arrangement is that the buffer protection component 5 can be detachably fixed at the front position of the plate-shaped sound insulation barrier body 1 by means of longitudinal sliding cooperation between the matching seat 404 and the matching groove 405 and transverse sliding cooperation between the limiting rod 408 and the limiting hole 406. At the same time, the matching seat 404 can be longitudinally disengaged from the matching groove 405 by simply pulling the limiting rod 408 out of the limiting hole 406, so that the buffer protection component 5 can be disassembled to the front position of the plate-shaped sound insulation barrier body 1. The combination and disassembly method of the buffer protection component 5 at the front of the plate-shaped sound insulation barrier body 1 is simple and easy to operate.
[0044] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7As shown, the assembly connection component 2 and the barrier splicing column 3 are optimized as follows. Specifically, in the assembly connection component 2, the splicing grooves 201 are all blind grooves in the vertical direction and are opened from the top surface of the barrier splicing column 3 from top to bottom, and the bottom surface of the splicing plate 202 is in contact with the bottom of the corresponding splicing groove 201. This arrangement facilitates the splicing plate 202 and the splicing groove 201 to have a good positioning guide design when sliding, and facilitates the accurate limit fit of the two. The top and bottom ends of the splicing plate 202 exceed the top and bottom surfaces of the plate-shaped sound insulation barrier body 1 respectively, and the connecting parts 203 are all bolts. In this arrangement, first, it is easy to ensure that after the plate-shaped sound insulation barrier body 1 is assembled with the barrier splicing column 3, the bottom surface of the plate-shaped sound insulation barrier body 1 is higher than the bottom end of the barrier splicing column 3, which facilitates the smooth installation of the fixing sleeve 403, and at the same time, it is convenient for the connecting part 203 to be quickly assembled and disassembled with the barrier column body with the help of tools. Specifically speaking of the barrier splicing columns 3, the bottom surfaces of the barrier splicing columns 3 are horizontally extended and fixed with fixed base plates 301, and the corners of the fixed base plates 301 are vertically provided with connecting through holes 302. The purpose of such arrangement is that the barrier splicing columns 3 can be vertically fixed to the ground by installing anchor bolts through the connecting through holes 302 of the fixed base plates 301. Preferably, after the connecting through holes 302 of the fixed base plates 301 are penetrated with anchor bolts for fixing, the bottom surfaces of the base plates 503 and the buffer lining plates 502 are both higher than the top ends of the anchor bolts to prevent interference with each other.
[0045] See also Figure 1-Figure 8 As shown, the disassembly assembly component 4 and the buffer protection component 5 are optimized as follows. Specifically, in the disassembly assembly component 4, the cross-sectional shapes of the matching seat 404 and the matching groove 405 along the horizontal vertical plane are both rectangular, so that the matching seat 404 and the matching groove 405 have a good positioning guide design when they slide and match in the longitudinal direction, which facilitates the rapid and accurate matching of the two. At the same time, the limiting holes 406 are all blind holes, and the distance between the handle 401 and the adjacent barrier splicing column 3 is greater than the length of the limiting rod 408 extending into the limiting hole 406. This arrangement first prevents the limiting hole 406 and the matching hole 505 from being connected to each other, and at the same time facilitates ensuring that the handle 401 has a sufficient outward pulling distance so that the inner end of the limiting rod 408 can smoothly escape from the limiting hole 406.
[0046] Specifically, in the buffer protection assembly 5, the connecting sleeves 504 are welded and fixed at the back corners of the base plate 503, and the connecting sleeves 504 are coaxially interference fit with the corresponding connecting rods 509. The reason for this arrangement is to facilitate the base plate 503 to be quickly combined and fixed with the connecting rods 509 through the connecting sleeves 504. At the same time, the rear end surface of the connecting sleeve 504 does not contact the front of the corresponding matching seat 404, so as to ensure that there is a certain gap between the connecting sleeve 504 and the matching seat 404, and then ensure that the base plate 503 can smoothly move backward for a distance when it is hit, so that the buffer spring 506 is deformed and buffered. The optional end plates 507 are all circular plates, and the end plates 507 can be inserted through the corresponding matching grooves 405 in the longitudinal direction. Such an arrangement facilitates that when the matching seat 404 and the matching groove 405 are combined and separated with each other, the end plates 507 can smoothly insert through the matching grooves 405, avoiding the situation where the matching seat 404 cannot be smoothly matched with the matching grooves 405. Specifically, the bottom surfaces of the base plate 503 and the buffer lining 502 are higher than the bottom end of the barrier splicing column 3 body, so as to prevent the bottom surfaces of the base plate 503 and the buffer lining 502 from being too low, and to prevent the base plate 503 and the buffer lining 502 from being unable to move and buffer when being hit. A plurality of reflective strips 508 are adhered and fixed to the front of the buffer lining 502, so that traffic participants can clearly observe the buffer lining 502. A plurality of buffer back strips 501 made of buffer material are fixed to the back of the base plate 503. Preferably, the buffer lining plate 502 and the buffer back strips 501 are made of rubber. The buffer back strips 501 are arranged vertically and the backs do not contact the front of the plate-shaped sound barrier body 1. Such an arrangement facilitates, firstly, three times of buffering of the impact force by elastic deformation after the buffer back strips 501 contact the plate-shaped sound barrier body 1 when an accidental impact occurs, and at the same time facilitates a certain gap to be left between the buffer back strips 501 and the plate-shaped sound barrier body 1, thereby ensuring that the buffer back strips 501 can smoothly move backwards for a distance when impacted, so that the buffer springs 506 can be deformed and buffered.
[0047] With the above structure, when the plate-shaped noise barrier body 1 is laid out and used, a plurality of barrier splicing columns 3 are firstly arranged on both sides of the road at equal intervals, and the spacing between two adjacent barrier splicing columns 3 should be just enough to enable the two sides of the plate-shaped noise barrier body 1 to be assembled with the barrier splicing columns 3 through the assembling connection components 2, and then the barrier splicing columns 3 can be erected and fixed to the ground by installing anchor bolts through the connecting through holes 302 of the fixed bottom plate 301, and then the two sides of the plate-shaped noise barrier body 1 can be respectively assembled and fixed with the erected barrier splicing columns 3 through the assembling connection components 2, so as to complete the erection, installation and layout of the plate-shaped noise barrier body 1, and because the assembly components 4 are disassembled and assembled A buffer protection component 5 is installed at the front of the plate-shaped noise barrier body 1, and the buffer protection component 5 and the plate-shaped noise barrier body 1 are parallel to each other. Then, the buffer protection component 5 can provide buffer protection for the rear plate-shaped noise barrier body 1, which is helpful to prevent the rear plate-shaped noise barrier body 1 from being damaged due to accidental collision during use. When the buffer protection component 5 is actually used, the surface of the base plate 503 of the buffer protection component 5 is covered with a buffer lining 502 fixed with a buffer material, and then when it is accidentally hit, the buffer lining 502 is first impacted and elastically deformed, so that the impact force can be buffered for the first time. At the same time, the buffer spring 50 is coaxially arranged on the periphery of the connecting rod 509 of the buffer protection component 5 6. Then, when an accidental impact occurs, the base plate 503 moves backward to drive the buffer spring 506 to stretch and deform, so that the impact force can be buffered for a second time. Moreover, since a plurality of buffer back strips 501 made of buffering materials are evenly fixed on the back of the base plate 503 of the buffer protection component 5, when an accidental impact occurs, the base plate 503 moves backward to drive the buffer back strip 501 to contact the plate-shaped sound insulation barrier body 1 and then elastically deform, so that the impact force can be buffered for a third time. The buffer protection methods of the buffer protection component 5 are diverse and highly reliable. At the same time, since the buffer protection component 5 adopts a multiple buffer protection method, it is ensured that the buffer protection component 5 has a good and reliable elastic buffer protection capability, and the buffer protection effect of the buffer protection component 5 on the plate-shaped sound insulation barrier body 1 is improved. The result is that when the buffer protection component 5 is combined and disassembled with the plate-shaped sound insulation barrier body 1, during the combination process, the buffer protection component 5 can be detachably fixed to the front position of the plate-shaped sound insulation barrier body 1 by means of longitudinal sliding cooperation between the matching seat 404 and the matching groove 405 and transverse sliding cooperation between the limiting rod 408 and the limiting hole 406. The fixing and combination method of the buffer protection component 5 at the front of the plate-shaped sound insulation barrier body 1 is simple and easy to operate, which makes it convenient to quickly fix the buffer protection component 5 at the front of the plate-shaped sound insulation barrier body 1 for buffer protection at the installation site. During the disassembly process, multiple people only need to hold the handle 401 outwards respectively and stretch the limit rod 408 through the tension spring 402 to make the limit rod 408 fall out of the limit hole 406.By pulling the rear limit rod 408 outward, the mating seat 404 can be longitudinally disengaged from the mating groove 405, so that the buffer protection component 5 can be disassembled from the front position of the plate-shaped sound insulation barrier body 1. The disassembly method of the buffer protection component 5 in front of the plate-shaped sound insulation barrier body 1 is simple and easy to operate, which is convenient for regular inspection and maintenance after the buffer protection component 5 is disassembled, and at the same time, it is convenient to separate the buffer protection component 5 from the plate-shaped sound insulation barrier body 1 for replacement and transportation.
