Description

Technical Field

[0001] The utility model relates to the technical field of sound barriers, in particular to a sound barrier device. Background Art

[0002] With the development of the transportation industry and the expansion of highways, people are troubled by noise while enjoying the convenience of transportation. When a road or highway is close to a residential area, a sound barrier is usually set up on the roadside to reduce the impact of noise on surrounding residents. In one prior art, the sound barrier includes a column and a screen body, the column has a slot, and the screen body is fixed in the slot by a spring buckle.

[0003] However, when an out-of-control vehicle hits the sound barrier, the spring clips are easily disengaged from the slots, causing the screen to detach from the column. If the sound barrier is placed on a bridge, once the screen falls to the lane below the bridge, it is easy for the screen to injure pedestrians or hit passing vehicles, causing casualties. Utility Model Content

[0004] The present application provides a sound barrier device for improving the connection effect between a screen body and a column.

[0005] The present application provides a sound barrier device, which includes a column, a screen body and a connecting component, wherein the connecting component connects the column and the screen body;

[0006] The upright column has a slot, and the side edge of the screen body is located in the slot; the wall of the slot has a first fixing hole, and the side edge of the screen body has a second fixing hole;

[0007] The connecting assembly includes a rope, the rope passes through the first fixing hole and the second fixing hole, and a lock buckle is arranged at the end of the rope.

[0008] In the above-mentioned sound barrier device, the pillars and the screen body can be flexibly connected under the connection of the rope. When an out-of-control vehicle hits the screen body, the pillars can pull the screen body, making it difficult for the screen body to separate from the pillars. In application scenarios such as bridges, the above-mentioned sound barrier device can reduce the risk of the screen body falling from the bridge to the road surface.

[0009] Optionally, the slot has a first side wall, a second side wall and a connecting wall located between the first side wall and the second side wall, and the second side wall is located on a side of the first side wall away from the road. Generally speaking, the spacing between the first side wall and the second side wall is greater than the thickness of the screen body, so that the side edge of the screen body is easily inserted into the slot during installation.

[0010] In order to improve the connection effect between the column and the screen body and improve the stability of the screen body, in a specific technical solution, the connection assembly also includes a fastener, one end of which is connected to the second side wall, and the other end of which abuts against the surface of the screen body. The fastener can generate a pressing force on the screen body, so that the screen body abuts against the first side wall, thereby suppressing the shaking of the screen body in the slot and improving the stability of the screen body.

[0011] When the fastener is specifically provided, in one technical solution, the fastener includes a bolt, the bolt having a head and a rod, the head being located on a side of the second side wall away from the screen body, the rod passing through the second side wall, and the end of the rod away from the head abutting against the surface of the screen body. The above fastener has a simple structure, is easy to install, can adapt to the installation of a variety of screens with different thicknesses, and has strong adaptability.

[0012] Optionally, the fastener may further include a limiting nut, the limiting nut being connected to the rod and located between the second side wall and the screen body. The limiting nut may prevent the bolt from coming out of the threaded hole of the second side wall, thereby further improving the stability of the screen body.

[0013] In addition to using fasteners to improve the connection effect between the column and the screen body and enhance the stability of the screen body, the above effect can also be achieved in other ways. For example, in an optional technical solution, the connection component also includes an elastic clip, which is arranged between the second side wall and the screen body, and the elastic clip is in a compressed state.

[0014] When the first fixing hole is arranged on the wall of the slot, the first fixing hole can be arranged on any one of the first side wall, the second side wall or the connecting wall of the slot. In one technical solution, the first fixing hole is arranged on the connecting wall. By arranging the first fixing hole on the connecting wall, on the one hand, the rope can be prevented from being exposed to the surface of the first side wall facing the road, thereby improving the appearance of the sound barrier device; on the other hand, the effect of the rope can be superimposed on the effect of the fastener or the elastic clip, thereby enhancing the stability of the screen body.

[0015] Optionally, the wall portion of the slot has two groups of the first fixing holes, the two groups of the first fixing holes are arranged along the height direction of the column, and each group includes at least one first fixing hole;

[0016] The rope has a first end and a second end, and from the first end to the second end, the rope passes through one of the two groups of the first fixing holes, the second fixing hole, and the other of the two groups of the first fixing holes in sequence.

[0017] When the second fixing hole is specifically provided, in one technical solution, the screen body includes a shell and a sound-absorbing material provided in the shell, and the second fixing hole is located on the side of the shell facing away from the road. In this way, the rope can be passed through the shell of the shell facing away from the road, avoiding the need to pass the rope through the surface of the screen body facing the first side wall, so that the surface of the screen body can abut against the surface of the first side wall, thereby achieving surface-to-surface contact with the first side wall, thereby improving the stability of the screen body.

[0018] When a lock is provided at the end of the rope, a lock may be provided at the first end and the second end of the rope respectively, and the lock and the rope are locked. When the screen body is hit by an out-of-control vehicle, the lock may abut against the surface of the column or the screen body to prevent the end of the rope from escaping from the column or the screen body. The first end and the second end of the rope may also be locked by the same lock, so that the ends of the rope are connected to form a closed loop, thereby improving the connection effect of the rope.

[0019] When the columns are specifically arranged, the columns include various structural forms. For example, the columns may be H-shaped columns. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose, technical scheme and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. However, the example implementation can be implemented in various forms and should not be construed as being limited to the implementations set forth herein. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted. The words expressing position and direction described in the embodiments of the present application are all illustrated by taking the accompanying drawings as examples, but changes may be made as needed, and the changes made are all included in the scope of protection of the present application. The drawings of the embodiments of the present application are only used to illustrate the relative position relationship and do not represent the true proportion.

[0026] It should be noted that specific details are described in the following description to facilitate understanding of the present application. However, the embodiments of the present application can be implemented in a variety of other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the embodiments of the present application. Therefore, the present application is not limited to the specific implementation methods disclosed below.

[0027] In order to facilitate the understanding of the sound barrier device provided in the embodiment of the present application, the following first introduces its application scenario. The sound barrier device can be applied to the roadside of a highway, expressway or elevated composite road to reduce the impact of noise on surrounding residents. The sound barrier device can also be applied to other sound insulation and noise reduction scenarios with noise sources.

[0028] Figure 1 An exploded schematic diagram of a sound barrier device provided in an embodiment of the present application, such as Figure 1 As shown, in one embodiment, the sound barrier device includes a column 10, a screen body 20 and a connecting assembly 30. The column 10 is the main force-bearing component in the sound barrier device. The column 10 can be fixed to the supporting structure of the road surface by bolts or welded to the supporting structure of the road surface. The column 10 has a slot 101, which extends along the height direction of the column 10 and is used to accommodate the side wall edge of the screen body 20.

[0029] When the column 10 is specifically set, the column 10 can be an H-shaped column or an I-shaped column, and both of these columns 10 have a slot 101. Of course, the column 10 can also be other structures with a slot 101, which are not listed one by one in this application. In one embodiment, the column 10 has two slots 101, which are located on two opposite sides of the column 10, and each slot 101 can be used to accommodate the side edge of the screen body 20.

[0030] The screen body 20 is the main sound insulation and sound absorption component in the sound barrier device. The screen body 20 includes a shell and a sound absorbing material arranged in the shell. Optionally, the shell is made of metal, fiberglass, color steel, PC, acrylic or aluminum. The sound absorbing material includes but is not limited to porous ceramics, glass wool or rock wool. The side edge of the screen body 20 is located in the slot 101 of the column 10 and is connected to the column 10 through the connecting component 30.

[0031] The connection assembly 30 includes a rope 31, which can connect the column 10 and the screen 20. In a specific implementation, the wall of the slot 101 has a first fixing hole 102, and the screen 20 has a second fixing hole 201. The rope 31 passes through the first fixing hole 102 and the second fixing hole 201, so as to connect the column 10 and the screen 20. The end of the rope 31 is provided with a lock 40, and the lock 40 can make the end of the rope 31 not easy to escape from the first fixing hole 102 and the second fixing hole 201, so that the connection between the column 10 and the screen 20 is relatively stable. Under the connection of the rope 31, the column 10 and the screen 20 can achieve a flexible connection. When the out-of-control vehicle hits the screen 20, the column 10 can pull the screen 20, so that the screen 20 is not easy to separate from the column 10. In application scenarios such as bridges, the above connection method can reduce the risk of the screen 20 falling from the bridge to the road surface.

[0032] For the same screen body 20 , two opposite sides of the screen body 20 may be connected to adjacent columns 10 via ropes 31 , respectively, or only one side of the screen body 20 may be connected to adjacent columns 10 via ropes 31 .

[0033] When the rope 31 is specifically set, the rope 31 can be a steel wire rope, or other ropes with greater strength. The rope 31 has a first end and a second end along the length direction, and a lock buckle 40 can be provided at the first end and the second end respectively. The lock buckle 40 and the rope 31 are clamped, and the size of the lock buckle 40 is larger than the size of the first fixing hole 102 and the second fixing hole 201. The first end and the second end of the rope 31 can also be locked by the same lock buckle 40, so that the end of the rope 31 is connected to form a closed loop.

[0034] Figure 2 A schematic diagram of an assembly of a column and a screen body in a sound barrier device provided in an embodiment of the present application, such as Figure 2As shown, in one embodiment, the slot 101 has a first side wall 1011, a second side wall 1012, and a connecting wall 1013 located between the first side wall 1011 and the second side wall 1012. The first side wall 1011, the second side wall 1012, and the connecting wall 1013 all extend along the height direction of the column 10, and the second side wall 1012 is located on the side of the first side wall 1011 away from the road. Generally speaking, the spacing between the first side wall 1011 and the second side wall 1012 is greater than the thickness of the screen body 20, so as to facilitate the insertion of the side edge of the screen body 20 into the slot 101 during the installation process.

[0035] Figure 3 for Figure 2 The AA cross-sectional view of the sound barrier device shown, as shown Figure 3 As shown, the connection assembly 30 further includes a fastener 32, one end of which is connected to the second side wall 1012, and the other end of the fastener 32 abuts against the surface of the screen body 20. During specific installation, the screen body 20 can be abutted against the surface of the first side wall 1011, and the end of the fastener 32 abuts against a side of the screen body 20 away from the first side wall 1011. The fastener 32 can suppress the shaking of the screen body 20 in the slot 101, thereby improving the stability of the screen body 20.

[0036] When the fastener 32 is specifically provided, the fastener 32 includes various structural forms. Figure 3 As shown, in one embodiment, the fastener 32 includes a bolt 321, the bolt 321 has a head and a rod, the head of the bolt 321 is located on the side of the second side wall 1012 away from the screen body 20, the rod of the bolt 321 passes through the second side wall 1012, and the end of the rod of the bolt 321 away from the head abuts against the surface of the screen body 20. In specific implementation, the second side wall 1012 has a threaded hole, and the rod of the bolt 321 passes through the threaded hole. During the installation process, by tightening the bolt 321, the end of the bolt 321 can push the screen body 20 to approach the first side wall 1011 until the screen body 20 abuts against the surface of the first side wall 1011, so that the screen body 20 is not easy to shake in the slot 101, thereby improving the stability of the screen body 20. The above-mentioned fastener 32 has a simple structure and is easy to install. It can adapt to the installation of various screen bodies 20 with different thicknesses and has strong adaptability.

[0037] Please continue to refer to Figure 3 The fastener 32 may further include a limiting nut 322, which is connected to the rod of the bolt 321 and is located between the second side wall 1012 and the screen body 20. The limiting nut 322 can prevent the bolt 321 from coming out of the threaded hole of the second side wall 1012, thereby further improving the stability of the screen body 20.

[0038] The number of fasteners 32 may be multiple, and these fasteners 32 may be distributed at different positions of the screen body 20. In a specific application scenario, the screen body 20 is a rectangular structure, and the four corners of the screen body 20 are connected to the columns 10 through the fasteners 32, respectively.

[0039] In addition to using fasteners 32 to improve the connection effect between the column 10 and the screen body 20 and enhance the stability of the screen body 20, the above-mentioned effects can also be achieved in other ways. For example, in one embodiment, the connection component 30 also includes an elastic clip, which is arranged between the screen body 20 and the second side wall 1012, and the elastic clip is in a compressed state. In the compressed state, the elastic clip can generate an elastic restoring force, which pushes the screen body 20 to approach the first side wall 1011, so that the screen body 20 abuts against the surface of the first side wall 1011, so that the screen body 20 is not easy to shake in the card slot 101, thereby generating the effect of enhancing the stability of the screen body 20.

[0040] In a specific configuration, the screen body 20 has a groove on one side facing the second side wall 1012, and the elastic clamp is located in the groove. The groove has a positioning function, so that the elastic clamp is not prone to tangential deformation.

[0041] When the above-mentioned sound barrier device is in use, when looking from the road toward the screen body 20, the screen body 20 will block the fasteners 32 or the elastic clips, so that pedestrians cannot see the fasteners 32 and the elastic clips, thereby improving the appearance of the screen body 20.

[0042] When the first fixing hole 102 is specifically provided, the number of the first fixing hole 102 may be one or more. Figure 1 As shown, in one embodiment, the number of the first fixing holes 102 is multiple, and the multiple first fixing holes 102 are divided into two groups, each group includes at least one first fixing hole 102, and the two groups of first fixing holes 102 are arranged along the height direction of the column 10. In specific implementation, the multiple first fixing holes 102 can be arranged in sequence along the height direction of the column 10. Among the multiple first fixing holes 102, one first fixing hole 102 at a higher position or multiple adjacent first fixing holes 102 form one group, and one first fixing hole 102 at a lower position or multiple adjacent first fixing holes 102 form another group.

[0043] Please continue to refer to Figure 1 , each group of the first fixing holes 102 includes one first fixing hole 102. That is, the column 10 has two first fixing holes 102, and the two first fixing holes 102 are arranged along the height direction of the column 10. When specifically arranged, the one of the two first fixing holes 102 at a higher position can be higher than any second fixing hole 201, and the other one at a lower position can be lower than any second fixing hole 201.

[0044] In a specific embodiment, after the upright column 10 and the screen body 20 are connected by the rope 31, the rope 31 passes through one of the two groups of first fixing holes 102, the second fixing hole 201, and the other of the two groups of first fixing holes 102 in sequence from the first end to the second end of the rope 31. That is, the first end of the rope 31 passes through one group of first fixing holes 102, and the second end of the rope 31 passes through the other group of first fixing holes 102.

[0045] In other embodiments, the column 10 is provided with a plurality of first fixing holes 102 along the height direction, and the screen body 20 is also provided with a plurality of second fixing holes 201 along the height direction. For the rope 31, from the first end to the second end of the rope 31, the rope 31 alternately passes through the first fixing hole 102 and the second fixing hole 201.

[0046] When the first fixing hole 102 is specifically arranged, the first fixing hole 102 can be arranged in any one of the first side wall 1011, the second side wall 1012 or the connecting wall 1013. Figure 1 As shown, in one embodiment, the first fixing hole 102 is arranged on the connecting wall 1013. In the above embodiment, by arranging the first fixing hole 102 on the connecting wall 1013, it is possible to avoid opening a hole in the first side wall 1011, so that the rope 31 does not need to pass through the first side wall 1011, thereby preventing the rope 31 from being exposed on the side of the first side wall 1011 facing the road, thereby improving the appearance of the sound barrier device.

[0047] In the above embodiment, by arranging the first fixing hole 102 on the connecting wall 1013, it is also avoided to open a hole on the second side wall 1012, so that the connection effect between the screen body 20 and the column 10 can be improved. This is because, in the scenario where the screen body 20 is abutted against the first side wall 1011 by the fastener 32 or the elastic clamp, under the action of the fastener 32 and the elastic clamp, the screen body 20 has a tendency to move away from the second side wall 1012. If the first fixing hole 102 is provided on the second side wall 1012, and the screen body 20 and the second side wall 1012 are fixed by the rope 31, the rope 31 will have a tendency to make the screen body 20 close to the second side wall 1012, thereby affecting the fixing effect of the screen body 20.

[0048] Therefore, in the specific arrangement of the first fixing hole 102, the first fixing hole 102 can be arranged on the connecting wall 1013, so that the screen body 20 and the connecting wall 1013 are fixed by the rope 31. In this way, on the one hand, the rope 31 can be prevented from being exposed to the surface of the first side wall 1011 facing the road, thereby improving the appearance of the sound barrier device; on the other hand, the effect of the rope 31 can be superimposed on the effect of the fastener 32 or the elastic clip, thereby enhancing the stability of the screen body 20.

[0049] When the second fixing hole 201 is specifically provided, the number of the second fixing hole 201 may be one or more. Figure 1 As shown, in one embodiment, there are multiple second fixing holes 201, and the multiple second fixing holes 201 are arranged at intervals along the height direction of the column 10, and the rope 31 passes through the multiple second fixing holes 201 in sequence. During specific assembly, the rope 31 can be passed through the multiple second fixing holes 201 first, and then the screen body 20 with the rope 31 is placed in the slot 101 of the column 10, and then the rope 31 is passed through the second fixing hole 201.

[0050] Please continue to refer to Figure 1 When the second fixing hole 201 is specifically arranged, the second fixing hole 201 can be arranged on the side of the outer shell of the screen body 20 facing away from the road, so that the rope 31 is passed through the shell of the outer shell facing away from the road. In this way, it is avoided that the rope 31 is passed through the surface of the screen body 20 facing the first side wall 1011, so that the surface of the screen body 20 can abut against the surface of the first side wall 1011, thereby achieving surface-to-surface contact with the first side wall 1011, thereby improving the stability of the screen body 20.

[0051] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
