Description

Technical Field

[0001] The utility model is specifically applicable to the field of buildings, specifically a bridge isolation fence with sound insulation effect. Background Art

[0002] In order to ensure the safety of vehicles and pedestrians on the bridge, the bridge isolation barrier can effectively reduce the risk of vehicles falling off the bridge and rushing into the opposite lane. However, in order to prevent the noise from residential buildings near the bridge from disturbing residents, a certain form or method is used to construct self-sound insulation or a sound insulation method combined with blocking the propagation of sound. The sound is continuously absorbed to weaken the sound propagation path and change the range of sound propagation.

[0003] In view of the technical problems existing in the bridge isolation fence with sound insulation effect mentioned above, it was found through searching that there is a patent number CN202222897246.6, which is a noise insulation fence, including a plate body and a third rotating shaft, both sides of the plate body are installed with splicing structures, and the front side of the outer wall of the splicing structure is provided with a first rotating shaft, the outside of the first rotating shaft is provided with a first mounting block, and the bottom of the first mounting block is provided with a first outer tube, the inside of the first outer tube is provided with a first inner rod, and the bottom of the first inner rod is provided with a second mounting block, the inside of the second mounting block is provided with a second rotating shaft, and a support frame is installed below the second rotating shaft, the third rotating shaft is provided at the rear side of the outer wall of the splicing structure, and the outside of the third rotating shaft is provided with a third mounting block; the utility model saves time and effort during splicing and installation, and can achieve the purpose of engineering construction environment management at the construction site on the one hand, and has better supporting strength, is not easy to tip over, and can be inserted into the soil, so that it is suitable for various engineering construction sites;

[0004] When the bridge barrier is in use, when the sound barriers are parallel, the sound waves will be reflected multiple times between the sound barriers and diffracted over the top of the sound barriers to the sound receiving point, thereby reducing the insertion loss of the sound barrier. In order to reduce the reflected sound, a sound-absorbing structure is generally added to the side of the sound barrier close to the road sound source. However, due to the use of sound insulation cotton for sound insulation, the adsorption capacity of the sound insulation cotton is poor during multiple reflections, the force of the sound waves in the rebound is small, and the sound insulation effect is poor. At the same time, different bridges are being installed, and due to the different bridge structures, the barrier is only installed by bolts, and the barrier is easy to loosen, resulting in unstable installation of the barrier.

[0015] 1. A bridge isolation railing with sound insulation effect provided by the present utility model. The extrusion cover is embedded on the outer surface of the sound insulation board and moves from outside to back on the outside of the sound insulation board. The buffer tube is formed by bonding two layers of airbags. The extrusion block is semicircular in shape. One end of the extrusion block abuts against the inside of the elastic cover. The elastic cover is made of foam cotton. When a vehicle moves and generates sound waves, the sound waves cause the extrusion cover to move inside the sound insulation board. The moving extrusion cover touches the sound insulation net, and the sound insulation net buffers the sound waves, enabling the excess sound waves to be transmitted to the movable rod through the gasket. Then, the extrusion block buffers the sound waves by extruding the elastic cover, allowing the sound-absorbing cotton to absorb the sound waves. The sound on the bridge can be buffered by the vibration structure for the sound waves, making the speed of the sound waves slow down and even be absorbed during continuous counteraction, thus enhancing the sound insulation effect.

[0016] 2. A bridge isolation railing with sound insulation effect provided by the present utility model. The rotating rod is rotatably arranged on both sides of the bottom of the mounting frame. The airbag is hermetically connected to the rotating rod. The airbag is of a fan-shaped structure. One side of the airbag is arc-shaped, and there is a triangular protrusion on the arc-shaped side of the airbag. One side of the airbag is of a folding structure. When pulling the extrusion strip, the extrusion strip supports the extrusion plate to fold the airbag. After the airbag is compressed, it pulls down the extrusion strip, fixing the mounting frame on the bridge, enabling the airbag to resume supporting both sides of the bridge. By pulling the connecting tube, the width of the airbag can be adjusted. The connecting tube is tied to both sides of the mounting frame, and the mounting bolts fix the mounting frame and the bridge. The adjustable airbag plays a role in fixing the installation of the bridge, preventing the bolts from loosening during long-term use. At the same time, the gap between the airbag and the bridge can be adjusted, ensuring an increase in the installation speed of the bridge. BRIEF DESCRIPTION OF THE DRAWINGS
