Description

Technical Field

[0001] This utility model relates to the field of noise reduction structure technology, and in particular to a noise reduction structure for steel trestle decks. Background Technology

[0002] A steel trestle is a temporary steel structure bridge used during bridge construction or maintenance. Typically made of steel, it boasts high load-bearing capacity and stability, serving as a temporary replacement for existing bridges for transportation. Compared to conventional bridges, temporary steel trestle bridges can be erected more quickly to meet temporary bridge needs. The design width of a steel trestle bridge is generally between 6 and 8 meters. Its structural components include steel pipe piles, scissor bracing connecting the steel casing, load-bearing beams atop the steel pipe piles, Bailey trusses, distribution beams, and bridge decks. This bridge structure is essentially the same as that of highway bridges. However, because trestle bridges are temporary projects serving the construction of permanent bridges, they must be quickly erected before bridge construction begins and typically dismantled after the permanent structure is completed. Steel trestle bridges are considered a profit center in the construction industry, especially in large-scale projects such as water-related construction, sea-crossing, river-crossing, and other large-scale engineering projects. The use of steel trestle bridges is not only due to the large scale and long duration of these projects, but also because their rental fees are very high.

[0003] In existing technologies, the conventional construction method for steel trestle bridges involves using steel pipe pile foundations, steel distribution beams, Bailey bridges, steel bridge decks, and ancillary facilities. These components are fixed by welding or bolting. However, after being put into use, the steel bridge decks vibrate under the pressure of vehicles, causing friction and impact between the steel decks and the bridge structure, resulting in significant noise. This affects the comfort of drivers and also impacts the surrounding environment. Therefore, there is an urgent need for a noise reduction structure for steel trestle bridge decks to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a noise reduction structure for steel trestle decks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A noise reduction structure for a steel trestle deck includes a bridge deck panel, a supporting frame on the bottom surface of the bridge deck panel, and a noise reduction component for noise reduction. The noise reduction component is disposed on the bottom surface of the bridge deck panel and includes: a first rubber plate disposed on the bottom surface of the bridge deck panel, a first fixing plate disposed on the bottom surface of the first rubber plate, the first fixing plate being fixedly installed to the supporting frame, a plurality of first fixing holes being opened on the four sides of the first rubber plate, steel wires being fixedly sleeved on the inner circular wall of the first fixing holes, the steel wires being fixedly installed to each other, a plurality of second fixing plates being disposed on the bottom surface of the supporting frame, a second rubber plate being fixedly installed on the bottom surface of the second fixing plates, a third rubber plate being fixedly installed on the bottom surface of the second rubber plates, a plurality of second fixing holes being opened on the inner bottom surface of the supporting frame, a first threaded post being movably sleeved on the inner circular wall of the second fixing hole, the first threaded post being fixedly installed to the second fixing plate, and a threaded ring being threadedly connected to the outer circular wall of the first threaded post.

[0007] As a further embodiment of this utility model, a protective skirt is fixedly attached to the outside of the supporting frame.

[0008] As a further embodiment of this utility model, the top surface of the first fixing plate is provided with a plurality of limiting grooves, and the bottom surface of the first rubber plate is fixedly installed with a limiting plate, the limiting plate being movably sleeved with the limiting grooves.

[0009] As a further embodiment of this utility model, a plurality of second threaded posts are fixedly installed on the bottom surface of the bridge deck, and a plurality of third fixing holes are opened on the top surface of the first rubber plate and the top surface of the first fixing plate. The second threaded posts are movably sleeved with the third fixing holes, and nuts are threadedly connected to the outer circular wall surface of the third fixing holes.

[0010] As a further embodiment of this invention, the protective skirt is made of rubber.

[0011] As a further embodiment of this utility model, a number of anti-slip strips are fixedly installed on the top surface of the bridge deck.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By using the bridge deck, supporting frame, first rubber plate, first fixing plate, second fixing plate, second rubber plate, third rubber plate, and first fixing hole in coordination, noise reduction of the bridge deck can be achieved. When the bridge deck is subjected to primary and secondary vibration damping by the first rubber plate and several second rubber plates, the noise generated by vibration of the bridge deck and other components is reduced. The protective skirts separate adjacent bridge decks to reduce noise, preventing friction and impact between the bridge deck and the bridge body, thereby reducing noise generated by vehicles running over them and avoiding impact on the surrounding environment. At the same time, the first and second rubber plates can be disassembled and replaced by rotating and removing the threaded ring and nut, which is convenient and practical.

[0023] Reference Figures 1-5 A noise reduction structure for a steel trestle deck includes a bridge deck 1, a supporting frame 2 on the bottom surface of the bridge deck 1, and a noise reduction component for noise reduction. The noise reduction component is disposed on the bottom surface of the bridge deck 1 and includes: a first rubber plate 3, which is disposed on the bottom surface of the bridge deck 1, and a first fixing plate 4 is disposed on the bottom surface of the first rubber plate 3. The first fixing plate 4 is fixedly installed with the supporting frame 2. Several first fixing holes 8 are respectively opened on the four sides of the first rubber plate 3, and the inner circular wall surface of the first fixing holes 8 is fixedly sleeved. A steel wire 9 is attached, and the steel wires 9 are fixedly installed together. Several second fixing plates 5 are provided on the bottom surface of the support frame 2. A second rubber plate 6 is fixedly installed on the bottom surface of the second fixing plate 5. A third rubber plate 7 is fixedly installed on the bottom surface of the second rubber plate 6. Several second fixing holes 12 are opened on the inner bottom surface of the support frame 2. A first threaded post 11 is movably sleeved on the inner circular wall of the second fixing hole 12. The first threaded post 11 is fixedly installed with the second fixing plate 5. A threaded ring 13 is threadedly connected to the outer circular wall of the first threaded post 11.

[0024] In this embodiment, a protective skirt 10 is fixedly sleeved on the outside of the supporting frame 2. Several limiting grooves 14 are opened on the top surface of the first fixing plate 4. A limiting plate 15 is fixedly installed on the bottom surface of the first rubber plate 3. The limiting plate 15 is movably sleeved with the limiting groove 14. Several second threaded posts 16 are fixedly installed on the bottom surface of the bridge deck 1. Several third fixing holes 17 are opened on the top surface of the first rubber plate 3 and the top surface of the first fixing plate 4. The second threaded posts 16 are movably sleeved with the third fixing holes 17. Nuts 18 are threadedly connected to the outer circular wall of the third fixing holes 17. The protective skirt 10 is made of rubber. Several anti-slip strips 19 are fixedly installed on the top surface of the bridge deck 1.

[0025] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When the bridge deck 1 is laid on the steel trestle, the protective skirt 10 separates and protects adjacent bridge decks 1. When a vehicle travels on the top surface of the bridge deck 1, the bridge deck 1 vibrates. The vibration is then reduced by the first rubber plate 3, thereby weakening the noise generated by the vibration. The strength of the first rubber plate 3 is reinforced by the steel wire 9, which pulls and supports the inner core of the first rubber plate 3 to prevent cracking due to downward pressure. The first fixing plate 4 supports the first rubber plate 3. Simultaneously, the limiting plate 15 is located inside the limiting groove 14, which limits and supports the limiting plate 15 and the first rubber plate 3, preventing lateral movement. Therefore, the weakened vibration continues to be transmitted to the second fixing plate 5, the second rubber plate 6, and the third rubber plate 7. The second rubber plate 6 further supports the second fixing plate 5 and the third rubber plate 7. Vibration is damped between the plates 7 to further reduce the transmission of vibration. When the second rubber plate 6 and the third rubber plate 7 need to be replaced, the second fixing hole 12 is rotated to remove it from the outside of the first threaded post 11, and the first threaded post 11 is pulled out from the inside of the second fixing hole 12. At the same time, the connection between the nut 18 and the second threaded post 16 is turned to remove the bridge deck 1 and replace the first rubber plate 3. This achieves the effect of reducing noise in the bridge deck 1. The bridge deck 1 is damped by the first rubber plate 3 and several second rubber plates 6, which reduces the noise generated by the vibration of the bridge deck 1. The protective skirt 10 separates the adjacent bridge decks 1 to reduce noise, avoids friction and impact between the bridge deck 1 and the bridge body, and reduces the noise generated by the car running over it, thus avoiding the impact on the surrounding environment. At the same time, the first rubber plate 3 and the second rubber plate 6 can be disassembled and replaced by rotating and removing the threaded ring 13 and the nut 18, which is convenient and practical.
