Description

Technical Field

[0001] This utility model belongs to the field of road technology, and specifically provides a road noise barrier component. Background Technology

[0002] Noise barrier assemblies are typically installed on both sides of roads (especially highways). These noise barriers consist of multiple vertical posts arranged sequentially along the road's direction, with a row of sound-absorbing panels inserted between adjacent posts. During installation, the posts are usually fixed to their designated positions on both sides of the road first, and then the sound-absorbing panels are inserted.

[0003] However, to improve the noise reduction effect of noise barrier components, their vertical height is generally quite large. Existing technologies require the use of ladders and cranes to insert the noise-absorbing panels from the top of the columns downwards. In related technical solutions, the inventors attempted to insert the noise-absorbing panels into horizontally arranged columns on the ground, then use lifting equipment to adjust the horizontal noise barrier to a vertical position and hoist it above the installation location for subsequent installation.

[0004] However, in existing technology, slots for inserting sound-absorbing panels are set on both the left and right sides of each column. After a set of sound-absorbing barriers (two columns and the sound-absorbing panel between the two columns) is assembled and hoisted, workers still need to use ladders and hoisting equipment to insert the sound-absorbing panels on the other side of the columns. If the sound-absorbing barrier components are simply set as multiple separately arranged modules, it will result in the columns occupying a large space and the gaps between adjacent columns affecting the sound-absorbing effect. Utility Model Content

[0005] The purpose of this invention is to provide a road noise barrier assembly that can at least solve one of the above-mentioned technical problems.

[0006] To address the aforementioned problems in the prior art, one or more embodiments of this utility model provide a road noise barrier assembly having a first direction along the road's driving direction and a second direction along the road's width direction. It includes a first barrier and a second barrier alternately arranged along the first direction. The first barrier includes two first posts, and the second barrier includes two second posts. A row of sound-absorbing panels is inserted between each of the two first posts and the two second posts. The first posts have a fan-shaped columnar first notch, and the second posts have fan-shaped columnar second notches. The first notches have a first end face that passes through the central axis of the first post, is parallel to the first direction, and a second end face that is perpendicular to the first direction. The second notches have a third end face that passes through the central axis of the second posts, is parallel to the first direction, and a fourth end face that is perpendicular to the first direction.

[0007] The first gap is located on the side of the first post away from the first barrier along the first direction and towards the center of the road along the second direction. The second gap faces the side of the second post away from the second barrier along the first direction and away from the center of the road along the second direction. The end of the first post near the second post is inserted into the second gap and abuts against the fourth end face, the end of the second post near the first post is inserted into the first gap and abuts against the second end face, and the first end face is in contact with the third end face.

[0008] The beneficial effects of one or more of the above technical solutions:

[0009] In this solution, the continuous alternating arrangement of columns and sound-absorbing panels is replaced with an alternating arrangement of first and second barriers, where the first column of the first barrier and the second column of the second barrier are adjacent to each other. This arrangement facilitates the separation of the columns and sound-absorbing panels into multiple modular structures that can be separated from each other, allowing each segment of the sound-absorbing barrier assembly to be assembled on the ground first, then hoisted to a vertical position and installed.

[0010] In this design, each adjacent first column has a first notch, and each second column has a second notch. The first and second notches face opposite directions, allowing the end of the first column closer to the second column to insert into the second notch and be stopped, and the end of the second column closer to the first column to insert into the first notch and be stopped. Furthermore, the first end face of the first notch and the third end face of the second column also stop each other. This arrangement, without altering the existing cylindrical structure of the columns, allows the first and second columns to interlock and stop each other through the notches, preventing gaps between them and thus avoiding any weakening of the sound-absorbing effect due to gaps.

[0011] Furthermore, this arrangement reduces the space occupied by the first and second posts along the road's extension direction through their interlocking, thus avoiding a reduction in the installation length of the sound-absorbing panels. The first and second posts also utilize their first and third end faces along the road width, which facilitates the positioning of the separately arranged first and second barriers, ensuring their stable installation on both sides of the road.

Detailed Implementation

[0018] Those skilled in the art should understand that the embodiments described below are merely preferred embodiments of this application, and these preferred embodiments are only used to explain the technical principles of this application and are not intended to limit the scope of protection of this application.

[0019] It should be noted that in the description of this application, terms such as "center," "upper," "lower," "top," "bottom," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] like Figures 1-4 As shown, this embodiment provides a road noise barrier assembly having a first direction along the road's driving direction and a second direction along the road's width direction. It includes a first barrier 1 and a second barrier 2 arranged alternately along the first direction. The first barrier 1 includes two first posts 7, and the second barrier 2 includes two second posts 11. A row of sound-absorbing panels is inserted between each of the two first posts 7 and the two second posts 11. The first post 7 has a fan-shaped columnar first notch 8, and the second post 11 has a fan-shaped columnar second notch 12. The first notch 8 has a first end face 9, parallel to the first direction and passing through the central axis of the first post 7, and a second end face 10, perpendicular to the first direction. The second notch 12 has a third end face 13, parallel to the first direction and passing through the central axis of the second post 11, and a fourth end face 14, perpendicular to the first direction.

[0021] The first gap 8 is located on the side of the first pillar 7 away from the first barrier 1 along the first direction and close to the center of the road along the second direction. The second gap 12 faces the second pillar 11 away from the second barrier 2 along the first direction and close to the center of the road along the second direction. The end of the first pillar 7 near the second pillar 11 is inserted into the second gap 12 and abuts against the fourth end face 14. The end of the second pillar 11 near the first pillar 7 is inserted into the first gap 8 and abuts against the second end face 10. The first end face 9 is in contact with the third end face 13.

[0022] Specifically, both the first pillar 7 and the second pillar 11 are cylinders, with the same height and diameter. The volumes of the first notch 8 and the second notch 12 are each one-quarter the volume of the first pillar 7 and the second pillar 11, respectively. That is, the outer contours of the first notch 8 and the second notch 12 are each one-quarter cylindrical.

[0023] In the first barrier 1 and the second barrier 2, the distance between the two first pillars 7 is equal to the distance between the two second pillars 11. Furthermore, along the road travel direction, the length of the first barrier 1 is equal to the length of the second barrier 2. The sound-dampening plate between the two first pillars 7 is the first sound-dampening plate 5, and the sound-dampening plate between the two second pillars 11 is the second sound-dampening plate 6.

[0024] In this embodiment, the first column 7 has a vertical first groove on the side near the center of the first barrier 1, and the second column 11 has a vertical second groove on the side near the center of the second barrier 2. The first groove and the second groove are used to insert a sound-absorbing plate.

[0025] Specifically, the first groove and the second groove are arranged vertically. The first groove opens near the top of the first column 7, and the second groove opens near the top of the second column 11, so that the sound-absorbing plate can be inserted between the two first columns 7 and the two second columns 11.

[0026] Furthermore, the first and second slots here have square cross-sections, with the first slot open on the side facing the center of the first barrier 1, and the second slot open on the side facing the center of the second barrier 2. Correspondingly, the sound-absorbing plate here is a lightweight square thin plate.

[0027] In this embodiment, the center of the first groove along the second direction coincides with the central axis of the first pillar 7, and the center of the second groove along the second direction coincides with the central axis of the second pillar 11. In this arrangement, the sound-absorbing plate is located at the center of either the first pillar 7 or the second pillar 11 along the road width direction.

[0028] In this embodiment, the first groove is formed by two first support plates 15 fixed to the outer side of the first column 7, and the second groove is formed by two second support plates 16 fixed to the outer side of the second column 11.

[0029] As a specific structural form, the first support plate 15 extends vertically without breaking apart on the outer side of the first column 7, and the second support plate 16 extends vertically without breaking apart on the outer side of the second column 11. In other structural forms, the first support plate 15 can be multiple segments extending vertically along the outer side of the first column 7, with gaps between adjacent segments to reduce the weight of the first support plate 15. Similarly, the second support plate 16 can also be formed by combining multiple separate segments.

[0030] In other structural configurations, the first and second grooves can be formed by recesses on the outer side of the first post 7 or the second post 11, without the need to utilize the aforementioned first support plate 15 or second support plate 16.

[0031] In this embodiment, the first column 7 has a first hole that penetrates itself along the second direction, and the second column 11 has a second hole that penetrates itself along the second direction. The first hole and the second hole are aligned and then fixed by bolts.

[0032] Specifically, the first and second holes here can be threaded holes, in which case the bolt is directly fixed to the first and second holes by threads. In other embodiments, the first and second holes here can be plain holes, and then the head of the bolt can be passed through the first and second holes and fixed by a nut.

[0033] In this embodiment, the gap between the first notch 8 and the second post 11 is filled with a first insert 3, and the gap between the second notch 12 and the first post 7 is filled with a second insert 4. The first insert 3 and the second insert 4 each have a vertical plane tangent to the outer circular surface of the first post 7 or the second post 11.

[0034] Specifically, the first insert 3 and the second insert 4 are used to fill the gaps, thereby reducing the probability of dirt accumulating in the gaps.

[0035] In this embodiment, both the first insert 3 and the second insert 4 are made of elastic material. The first insert 3 is fixed to the gap between the first notch 8 and the second post 11 by an adhesive, and the second insert 4 is fixed to the gap between the second notch 12 and the first post 7 by an adhesive.

[0036] In this embodiment, along the vertical direction, one end of the sound-absorbing plate has an insert block, and the other end has a slot. Adjacent sound-absorbing plates are connected by insert blocks and slots. Specifically, the slots are square grooves, and the insert blocks are square blocks.

[0037] Working principle: When using this device, firstly assemble the first barrier 1 and the second barrier 2 on the ground. Then connect the upper end of the first column 7 in the first barrier 1 to the lifting equipment, lift the first barrier 1 to a vertical position, and then fix the first column 7 to the preset foundation on both sides of the road.

[0038] Connect the upper end of the second column 11 in the second barrier 2 to the lifting equipment, and lift the second barrier 2 to a vertical position. The first column 7 of the first barrier 1 and the second column 11 of the second barrier 2 abut against each other. The first column 7 and the second column 11 can be connected to each other through the first notch 8 and the second notch 12. The first column 7 and the second column 11 are fixed with bolts.

[0039] Finally, the first insert 3 and the second insert 4 are fixed in the gaps of the first notch 8 and the second notch 12, respectively.
