In recent years, with the rapid development of economy and the acceleration of urbanization process, urban rail transit systems are rapidly developed, and the urban rail transit systems bring convenience for people to go out and also inevitably have certain influence on the surrounding environment. Currently, the main focus is on noise pollution to the surrounding environment.
At present, when the urban rail transit viaduct structure is designed in China, a thin-wall U-shaped beam structure is mainly adopted and a sound barrier is additionally arranged to reduce noise generated when rail transit travels, so that influence on the surrounding environment is reduced. A simple bridge structure system is mostly adopted in the urban rail transit viaduct structure in China, the span arrangement of the bridge is about 30m, and when the rail transit is carried out, large noise can be generated at the connecting position of two adjacent U-shaped beams. The noise generated when the rail transit travels cannot be completely reduced by only adopting a thin-wall U-shaped beam structure and additionally arranging a sound barrier.
Therefore, for the joint of the simply supported U-shaped beam of the rail transit, a running vehicle generates large noise when passing. How to design a device for reducing U type roof beam driving noise to reduce the noise that produces in the position department that meets of two adjacent U type roof beams when the moving vehicle passes through, this is the problem that the track traffic is waited to solve when the driving.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: overcome prior art's not enough, provide a device that reduces U type roof beam driving noise, produced noise when can effectively lower track traffic.
The technical scheme of the utility model is that:
the device for reducing the noise of the U-shaped beam during travelling comprises telescopic pieces, wherein each telescopic piece comprises two clamping plates and a rubber strip, and the two clamping plates are respectively and obliquely fixedly arranged on the same side web plate of two adjacent U-shaped beams; the clamping plate comprises two side plates and a vertical plate connected with the two side plates, and the two side plates are not connected to form a clamping groove between the vertical plate and the two side plates; the top surfaces of the clamping grooves are positioned on the top surfaces of the flange plates, the side surfaces of the clamping grooves are positioned on the opposite end surfaces of the two adjacent web plates, and the two ends of the rubber strip are fixedly arranged in the clamping grooves of the two clamping plates respectively; and telescopic pieces are arranged on the webs at the two sides of two adjacent U-shaped beams.
Preferably, the cross section of the clamping plate is dovetail-shaped, and two ends of the rubber strip are also dovetail-shaped.
Preferably, the clamping plate is a steel plate.
Preferably, the two ends of the rubber strip are fixed in the clamping grooves of the two clamping plates through sealing glue.
Preferably, the rubber strip is made of ethylene propylene diene monomer.
Compared with the prior art, the utility model, following beneficial effect has: the utility model discloses a device can form an enclosure space with the bottom plate expansion joint together, so can the effectual noise that reduces the position department of meeting of two adjacent U type roof beams of driving an automobile in-process, reduce the influence to the surrounding environment. Meanwhile, the telescopic deformation between the U-shaped beams under the action of temperature in a normal use state can be balanced; and the utility model discloses a device still has certain seal, can prevent diseases such as U type beam-ends portion infiltration, corruption, still easily inspects the change, and specially adapted is in the U type beam structure of higher driving noise environment.

Detailed Description
Example 1
As shown in fig. 1-5, the present embodiment provides a device for reducing driving noise of U-shaped beams, including an extensible member 4, where the extensible member 4 includes two clamping plates 41 and two rubber strips 42, the two clamping plates 41 are respectively and obliquely fixed on the same side web 2 of two adjacent U-shaped beams 1, the clamping plates 41 are steel plates, and the rubber strips 42 are made of ethylene propylene diene monomer; the clamping plate 41 comprises two side plates 412 and a vertical plate 411 connecting the two side plates 412, and the two side plates 412 are not connected to form a clamping groove between the vertical plate 411 and the two side plates 412; the top surfaces of the clamping grooves are positioned on the top surfaces of the flange plates 3, the side surfaces of the clamping grooves are positioned on the opposite end surfaces of the two adjacent web plates 2, and the two ends of the rubber strip 42 are fixedly arranged in the clamping grooves of the two clamping plates 41 respectively through sealant; and telescopic pieces 4 are arranged on the webs 2 at the two sides of the two adjacent U-shaped beams 1.
When the clamping plate 41 is used, the clamping plate is integrally cast when the U-shaped beam 1 is cast, so that the clamping plate 41 is fixed on the web plate 2 of the U-shaped beam 1.
