Bridge road guardrail with acoustic effect

Abstract

This application discloses a bridge and road guardrail with acoustic effects. The main barrier plate is set within a vertical groove. The middle of the main barrier plate and the lower end of the auxiliary barrier plate are connected to a lower mounting base. The auxiliary barrier plate is positioned corresponding to the guardrail plate. A square shaft passes through a horizontal circular groove and connects to multiple main barrier plates. In this bridge and road guardrail with acoustic effects, when the drive unit drives the barrier section to fully inward, the barrier section is located on the lower surface of the bridge deck. At this time, the acoustic effect of the barrier section is not activated, ensuring a good appearance. When the drive unit drives the barrier section to outward, the auxiliary barrier plate of the barrier section fits against the outer side of the guardrail plate, increasing the size of the passage. The middle of the main barrier plate enters between two guardrail plates, thus dividing the large space between the two guardrail plates into a sound-absorbing gap. When the thickness of the main barrier plate is greater, the barrier effect is also improved. Since the tops of both the auxiliary and main barrier plates extend beyond the guardrail plates, the height for achieving both acoustic barrier and sound-absorbing effects is increased.

Description

Technical Field

[0001] This utility model relates to the field of bridge and road auxiliary structures, and in particular to a bridge and road guardrail with acoustic effects. Background Technology

[0002] In existing technologies, the impact of noise generated by vehicles driving on roads on the surrounding environment is a factor that must be considered, especially since bridges, due to their special structure, have more significant noise problems.

[0003] Noise reduction methods used in bridge operation include sound barriers, sound barrier coverings, road surface noise reduction technologies, and bridge expansion joint noise reduction devices. Sound barriers are vertically installed barriers on both sides of roads or bridges to block and absorb noise generated by vehicles. They are typically made of concrete, metal, plastic, or composite materials, and their surfaces may be coated with sound-absorbing materials to enhance noise reduction. Sound barrier coverings are enclosed sound barriers installed above bridges or elevated roads, providing more comprehensive noise isolation. Road surface noise reduction technologies reduce noise generated by tire-road friction by altering road materials or structural design. For example, using porous asphalt or specially textured road surfaces can effectively reduce noise levels. Regarding bridge expansion joint noise reduction devices, these joints are prone to noise generation from passing vehicles; therefore, specially designed noise reduction devices are installed at these joints to reduce vibration and noise.

[0004] While the use of sound barriers and noise barriers can reduce noise, they can have a significant negative impact on the overall appearance of the bridge. Utility Model Content

[0032] Reference Figures 1 to 7 In one embodiment of this utility model, a bridge road railing with acoustic effects is installed on the bridge deck 010, characterized in that it includes:

[0033] The guardrail base 100 is strip-shaped and includes an upper horizontal base 110 and a vertical base 120 that are connected to each other and correspond to the upper surface and side surface of the bridge deck 010, respectively. The lower end of the vertical base 120 has a horizontal circular groove 121 that runs through it in length, and the outer end of the vertical base 120 has a plurality of vertical plate grooves 122 that pass through the horizontal circular groove 121 in thickness.

[0034] The guardrail section 200 includes a handrail 210 and a plurality of guardrail panels 220. The plurality of guardrail panels 220 are arranged along the upper horizontal seat 110 and their lower ends are connected to the upper horizontal seat 110. The handrail 210 connects the tops of the plurality of guardrail panels 220. The vertical plate groove 122 is arranged between two adjacent guardrail panels 220.

[0035] The barrier section 300 includes a lower mounting base 310, a square shaft 320, multiple main barrier plates 330, and multiple auxiliary barrier plates 340. The main barrier plates 330 are disposed within the vertical plate groove 122. The middle of the height of the main barrier plates 330 and the lower ends of the heights of the auxiliary barrier plates 340 are connected to the lower mounting base 310. The auxiliary barrier plates 340 are disposed corresponding to the guardrail plates 220. The square shaft 320 passes through the horizontal circular groove 121 and connects to the multiple main barrier plates 330. The diameter of the horizontal circular groove 121 is equal to the side length of the square shaft 320. times;

[0036] Drive unit 400 drives the square shaft 320 to rotate;

[0037] Wherein, after the driving unit 400 drives the barrier part 300 to flip inward, the barrier part 300 is located on the lower surface of the bridge deck 010; after the driving unit 400 drives the barrier part 300 to flip outward, the auxiliary barrier plate 340 of the barrier part 300 is attached to the outside of the guardrail plate 220 and its top extends beyond the guardrail plate 220, and the middle part of the main barrier plate 330 enters between the two guardrail plates 220 and its top extends beyond the guardrail plate 220.

[0038] While existing technologies can reduce noise by using sound barriers and soundproof coverings, they can also have a significant negative impact on the overall appearance of the bridge, especially in terms of height.

[0039] The bridge and road guardrail with acoustic effects provided by this utility model is installed on the bridge deck 010. The bridge and road guardrail includes a guardrail base 100, a guardrail part 200, a barrier part 300, and a drive part 400.

[0040] The guardrail base 100 is strip-shaped and includes an upper horizontal base 110 and a vertical base 120 connected to each other in cross-section. The upper horizontal base 110 and the vertical base 120 correspond to the upper surface and side surface of the bridge deck 010, respectively. The lower end of the vertical base 120 has a horizontal circular groove 121 extending through it in length. The outer end of the vertical base 120 has multiple vertical plate grooves 122 passing through the horizontal circular groove 121 in thickness.

[0041] The guardrail section 200 includes a handrail 210 and multiple guardrail panels 220. The multiple guardrail panels 220 are arranged along the upper crossbeam 110 and their lower ends are connected to the upper crossbeam 110. The handrail 210 connects the tops of the multiple guardrail panels 220. Vertical grooves 122 are provided between two adjacent guardrail panels 220.

[0042] The barrier section 300 includes a lower mounting base 310, a square shaft 320, multiple main barrier plates 330, and multiple auxiliary barrier plates 340. The thickness of the main barrier plates 330 is the same as the thickness of the vertical plate groove 122, and the main barrier plates 330 are disposed within the vertical plate groove 122. The middle part of the height of the main barrier plates 330 and the lower end of the height of the auxiliary barrier plates 340 are connected to the lower mounting base 310. The multiple auxiliary barrier plates 340 are disposed corresponding to multiple guardrail plates 220. The square shaft 320 passes through a horizontal circular groove 121 and is connected to the multiple main barrier plates 330, so that rotation of the square shaft 320 can drive the entire barrier section 300 to rotate. The diameter of the horizontal circular groove 121 is equal to the side length of the square shaft 320. The thickness of the main barrier plate 330 is 0.1 to 0.9 times the gap between adjacent guardrail plates 220, thus enabling the square shaft 320 to perform a smooth rotational motion within the transverse circular groove 121.

[0043] The drive unit 400 drives the square shaft 320 to rotate. The structure of the drive unit 400 can be various, such as hydraulic drive, pneumatic drive, or electric motor drive, as long as it can drive the rotation of the square shaft 320. When the drive unit 400 drives the square shaft 320 to rotate, the barrier unit 300 performs a flipping action.

[0044] After the drive unit 400 drives the barrier unit 300 to fully inward, the barrier unit 300 is located on the lower surface of the bridge deck 010. At this time, the acoustic function of the barrier unit 300 is not activated, ensuring the aesthetic effect. After the drive unit 400 drives the barrier unit 300 to outward, the auxiliary barrier plate 340 of the barrier unit 300 fits against the outside of the guardrail plate 220, increasing the size of the passage. The middle of the main barrier plate 330 enters between the two guardrail plates 220, thereby dividing the large space between the two guardrail plates 220 into a sound-absorbing gap. When the thickness of the main barrier plate 330 is greater, the barrier effect is also improved. The tops of both the auxiliary barrier plate 340 and the main barrier plate 330 extend beyond the guardrail plate 220, thus increasing the height for achieving acoustic barrier and sound absorption effects. When the barrier unit 300 is in a horizontal state, it can also provide some outward expansion support.

[0045] In summary, the guardrail section 200 is fixedly installed on the guardrail base 100, and the barrier section 300 is rotatably mounted on the guardrail base 100. After the drive section 400 drives the barrier section 300 to fully inward, the barrier section 300 is located on the lower surface of the bridge deck 010. At this time, the acoustic function of the barrier section 300 is not activated, ensuring the aesthetic effect. After the drive section 400 drives the barrier section 300 to outward, the auxiliary barrier plate 340 of the barrier section 300 fits against the outside of the guardrail plate 220, increasing the size of the passage. The middle of the main barrier plate 330 enters between the two guardrail plates 220, thereby dividing the large space between the two guardrail plates 220 into a sound-absorbing gap. When the thickness of the main barrier plate 330 is greater, the barrier effect is also improved. The tops of both the auxiliary barrier plate 340 and the main barrier plate 330 extend beyond the guardrail plate 220, thus increasing the height for achieving both acoustic barrier and sound-absorbing effects.

[0046] In one embodiment, the outer periphery of the square shaft 320 and the inner periphery of the transverse circular groove 121 are filled with a filler, and the filler is connected to the square shaft 320.

[0047] In this embodiment, considering that the cross-section of the horizontal circular groove 121 is circular while the cross-section of the square shaft 320 is square, the rotation process of the square shaft 320 is not smooth enough, so a filler is added. The filler fills the gap between the square and circular sections, thereby providing better support for the square shaft 320. Due to the presence of the vertical plate groove 122, the horizontal circular groove 121 is divided into multiple segments, so the filler includes multiple four-crescent-shaped flaps. The filler can be made of polyurethane or polytetrafluoroethylene, etc.

[0048] In one embodiment, the thickness of the main barrier plate 330 is 0.1 to 0.9 times the gap size between adjacent guardrail plates 220.

[0049] In this embodiment, the thickness of the main barrier plate 330 is limited. When the thickness of the main barrier plate 330 is small, the large space between adjacent guardrail plates 220 is divided into a sound-absorbing channel with relatively small sound absorption, while the appearance is guaranteed. When the thickness of the main barrier plate 330 is large, the main barrier plate 330 can play a stronger sound barrier role.

[0050] Reference Figures 3 to 4 In one embodiment, a lower horizontal seat 130 is provided at the lower end of the vertical seat 120, and the upper horizontal seat 110 and the lower horizontal seat 130 clamp the bridge deck 010.

[0051] In this embodiment, by defining the structure of the guardrail base 100, the connection between the guardrail base 100 and the bridge deck 010 is made more stable. Specifically, the dimensions of the lower cross seat 130 are set according to actual needs.

[0052] In one embodiment, the lower horizontal seat 130 is bolted to the vertical seat 120 and clamped to the bridge deck 010, and the free ends of the upper horizontal seat 110 and the lower horizontal seat 130 are both fastened to the bridge deck 010.

[0053] In this embodiment, the lower horizontal seat 130 and the vertical seat 120 are first set as separate structures, and then the free ends of the upper horizontal seat 110 and the lower horizontal seat 130 are structurally set so that they can be connected to the bridge deck 010, thereby improving the structural stability.

[0054] In one embodiment, the guardrail base 100 is connected to the bridge deck 010 by bolts.

[0055] In this embodiment, the guardrail seat 100 is fixed by bolts, such as expansion bolts, so that after the bridge deck 010 is processed, the guardrail seat 100 is installed on the bridge deck 010 by bolts.

[0056] In one embodiment, the main barrier plate 330 and the auxiliary barrier plate 340 are made of polymers.

[0057] In this embodiment, the main barrier plate 330 and the auxiliary barrier plate 340 are made of polymers, thereby reducing weight and cost. Using special polymers can also simultaneously achieve strength, lightweight, and weather resistance. The main barrier plate 330 and the auxiliary barrier plate 340 can be made of materials such as polyoxymethylene, nylon, or polycarbonate.

[0058] In one embodiment, both the main barrier plate 330 and the auxiliary barrier plate 340 are perforated mesh materials.

[0059] In this embodiment, both the main barrier plate 330 and the auxiliary barrier plate 340 are made of perforated mesh material. The perforated structure can achieve a sound-absorbing effect and at the same time increase the possibility of the whole vibrating under the action of sound waves, thereby producing a superior noise reduction effect; it can also reduce the overall weight to a certain extent.

[0060] Reference Figure 5 In one embodiment, the barrier portion 300 further includes an upper mounting base 350, which connects the upper ends of a plurality of main barrier plates 330 and a plurality of auxiliary barrier plates 340.

[0061] In this embodiment, the addition of the upper mounting base 350 improves the structural stability of the barrier portion 300, especially when the length dimensions of the main barrier plate 330 and the auxiliary barrier plate 340 are large, the addition of the upper mounting base 350 contributes significantly to the structural stability. The upper mounting base 350 can connect the main barrier plate 330 and the auxiliary barrier plate 340 in various ways, such as by a welded insertion connection.

[0062] In one embodiment, the drive unit 400 includes a motor and a reducer, wherein the motor drives the square shaft 320 to rotate via the reducer.

[0063] In this embodiment, a drive unit 400 is defined, in which the motor outputs increased torque after being converted by a reducer, thereby facilitating the rotation of the barrier unit 300.

[0064] In summary, the bridge and road guardrail with acoustic effects provided by this utility model has a guardrail section 200 fixedly installed on a guardrail base 100, and a barrier section 300 rotatably mounted on the guardrail base 100. After the drive section 400 drives the barrier section 300 to fully inward, the barrier section 300 is located on the lower surface of the bridge deck 010. At this time, the acoustic function of the barrier section 300 is not activated, ensuring the aesthetic effect. After the drive section 400 drives the barrier section 300 to outward, the auxiliary barrier plate 340 of the barrier section 300 fits against the outer side of the guardrail plate 220, increasing the size of the passage. The main barrier plate 330 extends into the space between the two guardrail plates 220, thereby dividing the large space between the two guardrail plates 220 into a sound-absorbing gap. When the thickness of the main barrier plate 330 is greater, the barrier effect is also improved. The tops of both the auxiliary barrier plate 340 and the main barrier plate 330 extend beyond the guardrail plate 220, thus increasing the height for achieving both acoustic barrier and sound-absorbing effects.
