And flange plate is parallel with bridge direction, fixed plate and two flange plates surround the placement space for placing abatvoix end, two edges of a wing
On plate opposite to each other to side be separately installed with extending bracket, one end of extending bracket is fixing end and is fixedly installed in flange plate
On, the other end of extending bracket is extension end and extend out to except the perspective plane of flange plate；Separately there is fixing bolt to extend through branch
The extension end of frame, and one end of fixing bolt is directed toward abatvoix and is equipped with backing plate, and rubber is provided between backing plate and abatvoix
Item simultaneously mutually pushes against, and is separately installed with spiral shell to opposite location nut positioned at the two sides for extending through bracket on fixing bolt.
The fixed device of bridge sound barrier acoustic described in the utility model, fixed plate and flange plate are together formed and are used for
The column of fixed abatvoix, wherein fixed plate optionally can be set as vertical or heeling condition, only need its peace with bridge
There is certain angle at dress rather than be parallel to each other；And extending bracket extends on the outside of flange plate, will be equipped with pad
The fixing bolt of plate penetrates on the extension end of extending bracket, and on fixing bolt positioned at extending bracket two sides be screwed into it is corresponding
Location nut；Then, one end of abatvoix is put into the placement space between fixed plate and two flange plates, at this point, sound-absorbing
It is opposite with backing plate in place of placement space on plate, rubber strip is put into buffer between this is opposite, then turns fixation
Being located at the location nut between extended between cushion block on bolt makes cushion block and rubber strip pressure under the action of the location nut
Then tight abatvoix turns another location nut again, fixing bolt is positioned on extending bracket.Pass through the bridge sound barrier
Abatvoix is installed on bridge by the use of sound-absorbing board fixer under the premise of not changing abatvoix specification, fixed plate and
The placement space that flange plate surrounds can apply limit from the side of abatvoix and two sides, meanwhile, it is installed on extending bracket solid
Extruding will be applied to abatvoix from abatvoix two sides by determining bolt and backing plate, on the one hand abatvoix and rubber strip can be made closely to paste
It closes, on the other hand, extending bracket has certain elasticity, and more accurate and effective pressure can be provided to abatvoix.In work
During work, the vibration that automobile is travelled on bridge and generated will make fixed plate, flange plate and abatvoix generate synchronous vibrating,
And during being somebody's turn to do, rubber strip will be mutually compressed with abatvoix always under the action of extending bracket, fixing bolt and backing plate, from
And the fixing intensity of abatvoix both can be improved, also it is possible to prevente effectively from rubber strip and abatvoix are fallen, to greatly improve
Its security performance.

Specific embodiment
A kind of fixed device of bridge sound barrier acoustic, including the fixed plate 1 being fixedly installed on bridge, the plate of fixed plate
Perpendicular on bridge or being obliquely installed on bridge, the two sides of fixed plate are separately installed with flange plate 2, and flange plate and bridge in face
Beam direction is parallel, and fixed plate and two flange plates surround the placement space for placing abatvoix end, on two flange plates opposite to each other to
Side is separately installed with extending bracket 3, and one end of extending bracket is fixing end and is fixedly installed on flange plate, extending bracket
The other end is extension end and extend out to except the perspective plane of flange plate；The extension end for separately thering is fixing bolt 4 to extend through bracket, and
It is directed toward abatvoix and backing plate 5 is installed, rubber strip 6 is provided between backing plate and abatvoix and is mutually supported in one end of fixing bolt
Tightly, spiral shell is separately installed with to opposite location nut 7 positioned at the two sides for extending through bracket on fixing bolt.
As shown in Fig. 2, extending bracket extends on the outside of flange plate, the fixing bolt for being equipped with backing plate is penetrated and is prolonged
It stretches on the extension end of bracket, and the two sides on fixing bolt positioned at extending bracket are screwed into corresponding location nut；Then, will
One end of abatvoix is put into the placement space between fixed plate and two flange plates, at this point, on abatvoix close to placement space it
Place is opposite with backing plate, is put into rubber strip between this is opposite to buffer, and then turns and is located between extension on fixing bolt
Location nut between cushion block makes cushion block and rubber strip compress abatvoix, then turns again under the action of the location nut
Another location nut, fixing bolt is positioned on extending bracket.
The fixed device of the bridge sound barrier acoustic, fixed plate 1 can be arranged perpendicular to bridge, as shown in Figure 3；?
It can be obliquely installed on bridge, as shown in Figure 4；To form bridge sound barrier of different shapes.In addition, flange plate 2 can be with
Protrude from the wherein side of fixed plate 1, as shown in Figure 3,4, for installing unilateral abatvoix, similarly, flange plate 2 can also in
Portion is connected to the side of fixed plate 1, and the two sides of flange plate extend to except the two sides of fixed plate, to install the sound-absorbing of two sides
Plate, as shown in Figure 5.In addition, being separately installed with several pieces of extending brackets 3 in different height on flange plate 2, on each extending bracket
It is provided with the fixing bolt 4 of backing plate 5；Or fixing bolt 4 is mounted on each extending bracket, all fixing bolts with it is same
Block backing plate 5 is connected, to realize different fixed effects, meets needed for different work.
As shown in fig. 6, extending bracket 3 includes the support plate 31 outwardly extended from flange plate 2, the end of support plate
Equipped with the mounting plate 32 being parallel to each other with flange plate, the end of mounting plate is the extension end of extending bracket, this kind of shape is prolonged
It is simple to stretch supporting structure, is easy to make and install, and can make extending bracket that there is certain elasticity, so as to preferably to suction
