Abstract
The invention provides a hanging type acoustic board used for a tunnel. The hanging type acoustic board comprises a board body and sound absorption materials. The board body is a perlite board body. Steel mesh reinforcement and the sound absorption materials are arranged in the board body. Lining steel plates are welded to the steel mesh reinforcement. A plurality of protrusions connected with a wall are evenly distributed on one side of the board body, and installing holes corresponding to the protrusions are formed in the other side of the board body. When the hanging type acoustic board is installed, the protrusions make contact with the surface of the wall, and the sound absorption plates and the wall body are connected by setscrews through the reserved installing holes. Because the protrusions are connected with the wall, cavities can be formed by parts, except the protrusions, of the body and the wall body, and silencing effect of the acoustic board is improved. The hanging type acoustic board used for the tunnel is simple in manufacturing technology, low in cost, convenient to install and long in service life.
Description
Technical field
The present invention relates to a kind of hanging acoustical board, particularly a kind of hanging acoustical board for tunnel.
Background technology
Along with economic development, it is more and more that urban road, high ferro are passed through tunnel, and the noise that vehicle produces during by tunnel can reflect into the car back and forth by tunnel inner wall, makes passenger in more severe noise circumstance.The noise reduction problem of tunnel internal starts to be subject to the people's attention.At present, the noise reducing apparatus of existing tunnel internal conventionally by column, suction (every) sound unit board forms, column vertically discharges along noise sources such as road, railways with uniform spacing conventionally, sound absorption unit board stands between two columns.But, the sound absorption equipment that this mode is manufactured, installation procedure is more loaded down with trivial details, and manufacturing process is also cumbersome, and cost of production is high, application life is low, acoustically effective is also not all roses.
Summary of the invention
The technical problem to be solved in the present invention is the defect that overcomes prior art, and the hanging acoustical board for tunnel two side walls that a kind of manufacturing process is simple, cost is low, easy for installation is provided.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of hanging acoustical board for tunnel of the present invention, comprises plate body, sound absorption material, and described plate body is perlite plate body, the built-in steel mesh reinforcement of described plate body, described sound absorption material is located in described plate body, on described steel mesh reinforcement, is welded with lining steel plate.
Preferably, described plate body one side is laid with the some lug bosses that are connected with wall, and described plate body opposite side and described lug boss opposite position are provided with installing hole.During installation, described jut contacts with body of wall wall, with setscrew, acoustical board and wall connecting is got up, because be connected with jut by reserved installing hole, thereby the body branch outside each jut and body of wall formation cavity, the soundproof effect of raising acoustical board.
Preferably, the lug boss and the installing hole that are arranged at described plate body one side are respectively more than four.Four above jut and installing holes are set, can make more stable being fixed on body of wall of plate body, increase the application life of muffler plate.
Preferably, on described lining steel plate, be welded with and connect silk mouthful in some, connect on silk mouthful uniform and described lining steel plate in described, connect on silk mouth in described and be connected with hook member.
Preferably, be arranged on described lining steel plate in to connect silk mouthful be four.
Preferably, described plate body height is that 810mm, length are 490mm.
The beneficial effect that the present invention reaches is:
(1) adopt the built-in steel mesh reinforcement of perlite plate body and weld lining steel plate, plate body is difficult for being corroded, and whole muffler plate is solid, durable, meets the long-term use at tunnel environment.
(2) do not need to arrange column, manufacturing process is simple, easy for installation, and manufacturing cost reduces greatly.
(3) by lug boss is set, thus the body branch outside each jut and body of wall formation cavity, the soundproof effect of raising acoustical board.
(4) by hook member is set, acoustical board more firmly can be installed on tunnel body of wall, significantly increased the application life of acoustical board.

The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.
Embodiment 1
As shown in Figure 1 to Figure 3, a kind of hanging acoustical board for tunnel of the present invention, comprise plate body 1, sound absorption material (not marking in figure), described plate body 1 is perlite plate body, the built-in steel mesh reinforcement 3 of described plate body 1, described sound absorption material is located in described plate body 1, on described steel mesh reinforcement 3, is welded with lining steel plate 4.
For elegant in appearance, be convenient to transportation, carrying, manufacturing plate body height is the acoustical board that 810mm, length are 490mm.For acoustical board is firmly fixed on tunnel wall, in described plate body 1 one sides, be laid with four lug bosses 7 that are connected with body of wall 9, described plate body 1 opposite side and described lug boss 7 opposite positions are provided with installing hole 2.During installation, described jut 7 contacts with body of wall 9 walls, by reserved installing hole 2 use setscrews 6, acoustical board plate body 1 and body of wall 9 is coupled together, because be connected with lug boss 7, thereby the board body part branch outside each lug boss 7 and body of wall 9 formation cavitys 8, the soundproof effect of raising acoustical board.After installation, at the seam crossing of each acoustical board, inlay high-strength cement, to strengthen the fastness of acoustical board.
