Description

Technical Field

[0001] The present invention relates to the technical field of closed sound barriers, and more specifically, to a novel lightweight fully closed sound barrier for urban viaducts. Background Art

[0002] According to the structural form, sound barriers can be divided into upright and fully enclosed types. Upright sound barriers can also be derived into L-type, Y-type, T-type, semicircular type, etc. according to the different top forms. The sound waves emitted by the noise source will change the path when encountering the sound barrier. Part of it will pass through the sound barrier to reach the sound receiving point, part of it will encounter the screen body and produce reflection, and the other part will bypass the top of the sound barrier to reach the sound receiving point. That is, there are three paths: transmission, reflection and diffraction. The upright sound barrier will form an acoustic shadow area behind its screen body. For the sound receivers in the acoustic shadow area, the upright sound barrier can achieve the purpose of effective protection. Sound barriers with different top forms are equivalent to increasing the height of the screen body, which will increase the sound insertion loss of the sound barrier to the acoustic shadow area to a certain extent, increasing by about 1-2.5dB (A).

[0003] Among them, the fully enclosed sound barrier completely encloses the road and vehicles in the screen body, completely seals off the noise source, makes the sound waves reflect multiple times in the screen body, thereby better consuming energy and attenuating, and also prevents diffracted sound waves. There are several disadvantages for the existing sound barriers. First, when the sound barrier is hit, the vibration generated by the impact cannot be eliminated. Second, there is no special base, or the base is not stable enough and is easily damaged. Third, the sound barrier is often set large and occupies a large area, but has no other additional functions except sound insulation and noise reduction. Summary of the invention

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1: Refer to the attached specification Figure 1-11 A novel lightweight fully enclosed sound barrier for an urban viaduct according to an embodiment of the present invention comprises a base 1, such as Figure 1 As shown, two groups of anti-collision guardrail components 2 are vertically inserted at the top of the base 1, and two groups of variable-section main columns 4 are arranged between the two groups of anti-collision guardrail components 2. The two groups of variable-section main columns 4 are fixedly inserted at both sides of the top of the anti-collision guardrail components 2. The anti-collision guardrail components 2 are located between the two groups of variable-section main columns 4 and a plurality of side sub-columns 7 are inserted at equal intervals. The variable-section main columns 4 and the side sub-columns 7 have the same shape. A plurality of roof purlins 9 are horizontally inserted between the two groups of variable-section main columns 4. Each group of roof purlins 9 runs through a plurality of side sub-columns 7, and an acrylic roof panel 8 is arranged inside the square formed between the side sub-columns 7 and the roof purlins 9. The acrylic roof panel 8 is fixedly connected to the side sub-columns 7, and the acrylic roof panel 8 and the roof purlin 9.

[0036] The fully enclosed sound barrier encloses the roads and vehicles completely within the screen body, completely sealing off the noise source, causing the sound waves to reflect multiple times within the screen body, thereby achieving better energy attenuation, while also preventing diffracted sound waves.

[0037] like Figure 7 As shown, the base 1 includes a base body 101, a slot 102 is opened at the top of the base body 101, the anti-collision guardrail assembly 2 includes a guardrail body 201 vertically inserted into the slot 102, the surfaces of the guardrail body 201 and the base body 101 are opened with a bolt hole 103, the inside of the bolt hole 103 is connected by a thread with a built-in hexagonal bolt 15, the anti-collision guardrail assembly 2 and the base 1 are fixedly connected by the built-in hexagonal bolt 15, the outer wall of the guardrail body 201 is attached with a plurality of silicone balls 203, the surface of the silicone balls 203 A movable vertical plate 202 is attached thereto, and the movable vertical plate 202 is vertically inserted into the interior of the guardrail body 201. A plurality of through holes 204 are opened on the surface of the movable vertical plate 202. The plurality of through holes 204 and the plurality of silicone balls 203 are staggered with each other. A silicone card column 205 is engaged inside the through hole 204. The portion of the silicone card column 205 located on the outer wall of the movable vertical plate 202 is connected with a plurality of silicone pipes 206. The plurality of silicone pipes 206 are staggered and communicated with each other, and the plurality of silicone card columns 205 are arranged in a state of being interconnected through the plurality of silicone pipes 206.

[0038] In the specific scheme, a gap is left between the guardrail body 201 and the movable vertical plate 202, and the gap is used to provide a certain installation space for the silicone balls 203 and part of the silicone posts 205. Secondly, when the movable vertical plate 202 is hit, the movable vertical plate 202 will be displaced toward the guardrail body 201, and the movable vertical plate 202 and the silicone balls 203 will be squeezed to provide buffering for the movable vertical plate 202. Secondly, when the movable vertical plate 202 moves toward the guardrail body 201, the surface of the guardrail body 201 squeezes the silicone posts 205, thereby causing the part of the silicone posts 205 located on the outer wall of the movable vertical plate 202 to expand instantly, and the silicone pipe 206 connected to the multiple silicone posts 205 also expands.

[0039] The end point of one side of the silicone column 205 away from the base 1 exceeds the end face of the base body 101. Its purpose is that when the sound barrier is hit, it first contacts the silicone column 205, and then the movable vertical plate 202 is pushed toward the guardrail body 201 for movement through the axial force exerted on the silicone column 205. Secondly, more silicone columns 205 and multiple silicone pipes 206 that are staggered and connected to each other are provided. Its purpose is that when the guardrail body 201 is subjected to a small pressure, the silicone pipe 206 can also expand. The multiple silicone pipes 206 that are staggered and connected to each other are to protect the surface of the movable vertical plate 202 as much as possible.

[0040] Embodiment 2: Further, as Figure 4 As shown, the surface of the anti-collision guardrail assembly 2 is bonded with a reinforcing rib assembly 3, and the reinforcing rib assembly 3 includes an L-shaped bonding plate 301, and a plurality of triangular fixing plates 302 are welded inside the L-shaped bonding plate 301. Two groups of bolt holes 303 set at 90 degrees are opened inside the cross-section surrounded by the L-shaped bonding plate 301 and the triangular fixing plate 302. The reinforcing rib assembly 3 is located inside the bolt hole 303 and is connected with an internal round head bolt 14 through a thread. The reinforcing rib assembly 3 is fixedly connected to the base 1 and the anti-collision guardrail assembly 2 through the internal round head bolt 14.

[0041] The L-shaped bonding plate 301 and the triangular fixing plate 302 form a triangle, which has stability. The anti-collision guardrail assembly 2 is inserted into the inside of the base 1. When the outer wall of the anti-collision guardrail assembly 2 is hit, the part connected between the base 1 and the anti-collision guardrail assembly 2 is easy to break. Therefore, a reinforcing rib assembly 3 is connected to the connection between the anti-collision guardrail assembly 2 and the base 1 by bolts. The cross-section of the reinforcing rib assembly 3 is triangular and has stability. While strengthening the connection between the base 1 and the anti-collision guardrail assembly 2, the surface of the reinforcing rib assembly 3 is completely fitted with the base 1 and the anti-collision guardrail assembly 2.

[0042] Further, such as Figure 5As shown, a square groove is opened at the bottom end of the L-shaped laminating plate 301, and a rotating shaft 306 is rotatably connected inside the square groove. A rotating horizontal plate 305 is rotatably installed on the surface of the rotating shaft 306. A hinged vertical plate 304 is hinged at the top end of the L-shaped laminating plate 301, and the width of the rotating horizontal plate 305 is the vertical length of the L-shaped laminating plate 301.

[0043] The length and width of the square groove are both larger than the length and width of the rotating horizontal plate 305, which makes it convenient for the rotating horizontal plate 305 to flip over from the inside of the square groove, wherein the rotating horizontal plate 305 and the hinged vertical plate 304 conveniently cover the built-in round head bolt 14 and the bolt hole 2 303 to prevent dust from entering the inside of the bolt hole 2 303. Secondly, when the hinged vertical plate 304 is rotated to horizontal, the rotating horizontal plate 305 is rotated to vertical, and a temporary bench can be built by overlapping the hinged vertical plate 304 and the rotating horizontal plate 305 for pedestrians to take a temporary rest.

[0044] Embodiment 3: Further, as Figure 8 As shown, two groups of horizontal cross plates 21 are fixedly installed on the top of the base 1, and a plurality of center column double column foot connectors 18 are fixedly connected to the top of each group of horizontal cross plates 21. A center column 10 is fixedly connected to the surface of each center column double column foot connector 18, and the tops of the plurality of center columns 10 are fixedly connected to the surface of the roof purlin 9. An X-shaped fixing plate 20 is fixedly connected between the two groups of center columns 10 located on both sides of the horizontal cross plates 21, and an intermediate sound absorbing plate 19 is installed between the two groups of center columns 10 located in the middle of the horizontal cross plates 21.

[0045] The middle column 10 is used to provide a supporting force for the top of the multiple sound barriers. At the same time, a group of sound absorbing panels are added in the middle of the sound barriers to enhance the reflection and absorption of sound.

[0046] Further, such as Figure 1 As shown, side sound insulation panels 5 are inserted inside the two groups of variable-section main columns 4, and side sound absorption panels 6 are arranged between the side sound insulation panels 5 and the anti-collision guardrail assembly 2. The side sound insulation panels 5 are fixedly connected to the anti-collision guardrail assembly 2 through the side sound absorption panels 6.

[0047] The entire sound barrier is divided into partitions along the trajectory direction of the variable-section main column 4, and the entire sound barrier is symmetrically distributed about the vertical center line of the middle column 10, namely side sound absorbing panels 6-side sound insulation panels 5-roof sound absorbing panels-roof surfaces-side sound insulation panels 5-side sound absorbing panels 6. The roof surfaces and side sound insulation panels 5 are both made of acrylic material, which is convenient for light transmission. Acrylic is an important thermoplastic material that was developed earlier, has good weather resistance, can be produced in a large area, and has a simple fixing method. The side sound absorbing panels 6, the middle column 10 and the roof sound absorbing panels are all made of new foam aluminum sound materials.

[0048] Further, such as Fig. 9As shown, the middle sound absorbing plate 19 adopts a new foam aluminum sound material. The middle sound absorbing plate 19 includes a galvanized steel back plate 1901, a porous aluminum plate 1902 and a foam aluminum plate 1903. The galvanized steel back plate 1901 and the porous aluminum plate 1902, the porous aluminum plate 1902 and the foam aluminum plate 1903 are connected by rivets. A silencer cavity is arranged between the galvanized steel back plate 1901 and the porous aluminum plate 1902. The thickness of the galvanized steel back plate 1901 and the porous aluminum plate 1902 is 1.5 mm, the thickness of the foam aluminum plate 1903 is 12 mm, and the gap thickness of the silencer cavity is 30 mm.

[0049] The new foam aluminum sound barrier adopts a multi-layer composite structure. The main material of the screen, foam aluminum, is made by melt foaming. The surface of the foam aluminum is porous and has a large number of concave-convex structures and small chamber structures. It absorbs sound through surface diffuse reflection and dissipates sound energy through microporous structures. It can also use the principle of Helmholtz resonance absorber and cavity structure to greatly improve the sound absorption effect. The pore wall of foam aluminum is thin, generally less than 0.5mm, and the vibration of the pore wall is also a way to eliminate noise. In addition, some cracks inside the foam aluminum will also play a certain role in absorbing sound energy. The sound absorption performance of the punched foam aluminum is more superior, and it has a larger use space in the promotion and application of new environmentally friendly sound barriers.

[0050] Embodiment 4: Further, as Fig.10 As shown, a hidden groove 16 is provided on the surface of the base 1, and a cleaning component 17 is engaged inside the hidden groove 16;

[0051] like Fig.11 As shown, the cleaning component 17 includes an end clamp 1706 located inside the hidden groove 16, and a rectangular rotating plate 1701 is rotatably installed on a side of the end clamp 1706 away from the base 1. The plate body of the rectangular rotating plate 1701 is a telescopic plate body, and two groups of rectangular slots 1702 are opened on the surface of the rectangular rotating plate 1701. The positions of the two groups of rectangular slots 1702 correspond horizontally. One end of the rectangular rotating plate 1701 is threadedly connected to a threaded end 1703, and a horizontal rotating rod 1704 is rotatably installed on the surface of the threaded end 1703, and the surface of the horizontal rotating rod 1704 is inserted with dense bristles 1705.

[0052] The end clamp 1706 is slidably installed inside the hidden groove 16. When the cleaning component 17 needs to be taken out, the rectangular rotating plate 1701 can be stretched outward, thereby causing the end clamp 1706 to move in the direction of the pulling force, and then the rectangular rotating plate 1701 is disengaged from the inside of the hidden groove 16, and then the threaded end 1703 is rotated, and the threaded end 1703 and the horizontal rotating rod 1704 are horizontally pulled out from the inside of the hidden groove 16, and then the rectangular rotating plate 1701 is flipped over, and the horizontal rotating rod 1704 is threadedly connected again for assembly.

[0053] Further, such as Figure 3 As shown, the rotating connection component 11 includes an end plug column 1101 rotatably installed inside the middle column 10, and the surface of the end plug column 1101 is fixedly connected with a rotating shaft 1103. The shaft body of the rotating shaft 1103 is a telescopic shaft body, which is convenient for telescoping and thus matching the cleaning component 17. Two groups of grooves 1102 are opened on the surface of the rotating shaft 1103, and two groups of positioning columns 13 are horizontally inserted on the surface of the middle column 10. The outer diameter of the positioning column 13 is consistent with the groove diameter of the groove 1102.

[0054] When the rotating shaft 1103 rotates to a horizontal position, the positioning column 13 is just engaged in the inside of the slot 1102 , which fixes the rotating shaft 1103 in a horizontal position.

[0055] Further, such as Figure 2 As shown, the top end of the rotating shaft 1103 is rotatably connected to a circular boss 1104, and the rotating connection component 11 is located at one end of the circular boss 1104 and is fixedly connected to a locking component 12, and the locking component 12 includes an end connection base 1201, and the upper and lower end surfaces of the end connection base 1201 are fixedly connected to two groups of telescopic elastic round rods 1203, and one end of each group of telescopic elastic round rods 1203 is fixedly connected to an L-shaped clamping plate 1202, and the opposite end surfaces of the two groups of L-shaped clamping plates 1202 are fixedly connected to built-in clamping blocks 1204.

[0056] The two groups of built-in card blocks 1204 are arranged in correspondence with each other up and down, and correspond exactly to the two groups of rectangular card slots 1702 on the surface of the rectangular rotating plate 1701. By engaging the built-in card blocks 1204 inside the rectangular card slots 1702, the cleaning component 17 is connected to the engaging component 12.

[0057] Further, such as Fig.10 As shown, the rotating connection component 11 is engaged with the interior of the cleaning component 17, and the engaging component 12 is L-shaped.

[0058] The entire sound barrier is a frame structure, and the roof is made of acrylic material. The surface of the sound barrier needs to be cleaned regularly after being exposed to the outside world for a long time. The manual climbing method is not only unsafe, but also complicated. The design engages the cleaning component 17 in the interior of the engaging component 12, and mounts the bristles 1705 on the top of the sound barrier. The engaging component 12 is used as a mounting point, and the rectangular rotating plate 1701 is moved left and right. The lower half of the engaging component 12, and the upper half of the cleaning component 17 slides on the surface of the sound barrier. The rectangular rotating plate 1701 is a telescopic plate. Under the action of gravity, the bristles 1705 are always in contact with the surface of the sound barrier. The lever method is used to make it easy to operate and save manpower.

[0059] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection.
