Description

Technical Field

[0001] The utility model relates to the technical field of sound-absorbing barriers, in particular to a sound-absorbing barrier for bridge construction. Background Art

[0002] Bridge construction is the process of building a bridge according to the design content; it mainly refers to bridge construction technology and construction organization, construction management, and construction quality. With the development of science and technology, noise is easily generated during bridge construction, and noise-absorbing barriers are used for green and environmental protection.

[0003] Most of the existing sound-absorbing barriers used in bridge construction are composed of a single sound-absorbing panel. As a result, the intensity of the sound waves generated cannot be reduced layer by layer during transmission, which in turn affects the sound insulation effect and cannot meet the requirements of bridge construction. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a sound-absorbing barrier for bridge construction, which solves the problem that a single sound-absorbing panel cannot achieve the gradual reduction of sound wave intensity, affects the sound insulation effect, and cannot meet the use requirements of bridge construction. When the decreasing sound waves are transmitted to the sound-absorbing bottom pipe, part of the sound waves are reflected and collided on the inner wall of the sound-absorbing bottom pipe, so that the sound wave intensity is further weakened. At the same time, part of the sound waves continue to be transmitted through the sound-absorbing columns. In this process, due to the reduction in the width of the transmission path, the problem of gradual reduction of the sound wave intensity is achieved.

[0005] To achieve the above objectives, the utility model adopts the following technical solution: a sound-absorbing barrier for bridge construction, comprising a base assembly, a barrier assembly, a sound insulation assembly, and a sound-absorbing assembly, the base assembly comprising a base and a mounting seat, the barrier assembly comprising a barrier plate, the sound insulation assembly comprising a sound-absorbing plate, the sound-absorbing assembly comprising a sound-absorbing top pipe, a mounting groove is provided on the inner side of the upper part of the base, a plug-in plate is provided at the lower end of the mounting seat, connecting plates are symmetrically connected at both ends of the mounting seat, a perforated mesh is provided on the inner side of the barrier plate, a yield groove is provided on the inner side of the barrier plate, one end of the sound-absorbing plate is connected to the sound insulation plate, a partition column is provided at the end of the sound insulation plate away from the sound insulation plate, a gypsum board is connected to the end of the partition column away from the sound insulation plate, a sound-absorbing inner pipe is connected to the inner wall of the sound-absorbing top pipe, a sound-absorbing bottom pipe is connected to the lower end of the sound-absorbing top pipe, a positioning ring is connected to the inner wall of the sound-absorbing bottom pipe, and a sound-absorbing column is provided on the inner side of the positioning ring.

[0006] The beneficial effects of the utility model are as follows: after the sound waves are transmitted into the sound-absorbing top pipe, part of the sound waves are reflected and collided on the inner wall of the sound-absorbing top pipe, so that the intensity of the sound waves is weakened, and at the same time, part of the sound waves continue to be transmitted to the sound-absorbing bottom pipe through the sound-absorbing inner pipe. In this process, since the inner diameter of the sound-absorbing inner pipe is smaller than the inner diameter of the sound-absorbing top pipe, the width of the sound wave transmission path is reduced. At the same time, part of the sound waves are absorbed by the sound-absorbing inner pipe during the transmission of the sound waves in the sound-absorbing inner pipe, so that the intensity of the sound waves is weakened. The positioning ring is provided to fix the sound-absorbing column and realize the connection between the sound-absorbing column and the sound-absorbing bottom pipe. After the decreasing sound waves are transmitted into the sound-absorbing bottom pipe, part of the sound waves are reflected and collided on the inner wall of the sound-absorbing bottom pipe, so that the intensity of the sound waves is further weakened, and at the same time, part of the sound waves continue to be transmitted through the sound-absorbing column. In this process, due to the reduction in the width of the transmission path, the intensity of the sound waves is weakened layer by layer.

[0007] To facilitate the insertion of the plug board into the mounting slot from the top and side:

[0008] As a further improvement of the above technical solution: the mounting seat and the plug board are arranged as an integral structure, the size of the mounting groove matches the size of the plug board, and a reinforcing rib is arranged at one end of the connecting plate away from the mounting seat.

[0009] The beneficial effect of this improvement is: when in use, the base is connected to the edge of the bridge, and then the plug-in board is smoothly inserted into the installation groove, and then the connecting plate and the base are assembled and connected using bolts. Through the setting of the installation groove, a groove body for inserting the plug-in board is provided, and it is convenient for the plug-in board to be inserted into the installation groove from the top and the side.

[0010] To improve the safety of noise barriers during use:

[0011] As a further improvement of the above technical solution: a protective plate is connected to the top of the barrier plate, and the perforated mesh is symmetrically arranged at the upper and lower ends of the give way slot.

[0013] In order to achieve the first step of reducing the intensity of the sound wave:

[0014] As a further improvement of the above technical solution: the inner side of the sound absorbing board is filled with sound insulation cotton blocks.

[0015] The beneficial effect of this improvement is that through the setting of the sound-absorbing panel, when the sound waves are transmitted, the sound-absorbing panel has a multi-fiber structure so that the sound waves are reflected, superimposed and collided by the fibers when passing through, thereby converting the sound wave energy into heat energy. At the same time, the sound wave intensity gradually weakens in this process, achieving the first step of weakening the sound wave intensity.

[0016] In order to ensure that part of the sound waves are absorbed by the sound-absorbing inner tube during the transmission process of the sound waves:

[0017] As a further improvement of the above technical solution: the end of the sound-absorbing top pipe away from the sound-absorbing bottom pipe is opened, and the top of the sound-absorbing bottom pipe penetrates the wall of the sound-absorbing top pipe and extends to connect with the inner cavity of the sound-absorbing inner pipe.

[0018] The beneficial effect of this improvement is that when the sound waves are transmitted into the sound-absorbing top pipe, part of the sound waves are reflected and collided on the inner wall of the sound-absorbing top pipe, so that the intensity of the sound waves is weakened, and at the same time, part of the sound waves continue to be transmitted to the sound-absorbing bottom pipe through the sound-absorbing inner pipe. In this process, since the inner diameter of the sound-absorbing inner pipe is smaller than the inner diameter of the sound-absorbing top pipe, the width of the sound wave transmission path is reduced. At the same time, part of the sound waves are absorbed by the sound-absorbing inner pipe during the transmission of the sound waves in the sound-absorbing inner pipe, thereby reducing the intensity of the sound waves.

[0019] To increase the strength of the sound insulation components:

[0020] As a further improvement of the above technical solution: a groove for installing a sound absorbing component is opened on the inner side of the sound insulation board, one end of the sound insulation board close to the sound absorbing board is located at the same horizontal plane as the sound absorbing top pipe, and one end of the sound insulation cavity of the sound insulation board space is located at the same horizontal plane as the sound absorbing bottom pipe.

[0021] The beneficial effect of this improvement is that the sound insulation board is provided to install and fix the sound absorbing component, while improving the use strength of the sound insulation component.

[0022] In order to achieve the buffering of sound wave intensity:

[0023] As a further improvement of the above technical solution: the cavity between the sound insulation board and the gypsum board is divided into a plurality of sound insulation cavities by dividing columns, and the dividing columns are long strips of rubber blocks.

[0024] The beneficial effect of this improvement is that the partition column is used to separate the gypsum board and the sound insulation board. At the same time, due to the softness of the partition column, the shock absorbing effect of the gypsum board can be increased, and the cavity state of the sound insulation cavity can achieve buffering of the sound wave intensity.

[0025] In order to achieve the gradual reduction of the intensity of sound waves:

[0026] As a further improvement of the above technical solution: the height of the sound-absorbing column is the same as the height of the sound-absorbing bottom tube, and the lower end of the sound-absorbing column and the lower end of the sound-absorbing bottom tube are located in the same horizontal plane.

[0027] The beneficial effect of this improvement is that the positioning ring is set to fix the sound-absorbing column and realize the connection between the sound-absorbing column and the sound-absorbing bottom tube. When the decreasing sound waves are transmitted into the sound-absorbing bottom tube, part of the sound waves are reflected and collided on the inner wall of the sound-absorbing bottom tube, so that the sound wave intensity is further weakened. At the same time, part of the sound waves continue to be transmitted through the sound-absorbing column. In this process, due to the reduction of the width of the transmission path, the sound wave intensity is weakened layer by layer. BRIEF DESCRIPTION OF THE DRAWINGS
