Description
Technical field
The utility model belongs to building material technical field, and in particular to a kind of noise reduction fire prevention venting of dust explosion plate.
Background technique
Fire prevention venting of dust explosion plate is the construction material for constructing wall, roof with explosion hazard place etc., with city
The continuous reinforcement of cityization construction, people concentrate on indoor scene and gradually increase, fire-proof and explosion-proof for these public places
Safety has to reach good guarantee.And venting of dust explosion plate of preventing fires occurs in fire and does not have explosion time, can be formed to Fire Field
Certain flame retardant effect, and when explosion time occurs, venting of dust explosion plate, which can pop, to form fragment, abrupt release room pressure, reduces building
The degree of impairment of object.But when venting of dust explosion plate explodes to form fragment, tiny fragment scatters impact can be to close to venting of dust explosion plate
Crowd damages.In addition, the general erasure effect of existing fire prevention venting of dust explosion plate is poor, it is easy to cause more serious noise pollution.
Application No. is the utility model patents of CN201820564230.4 to disclose a kind of fire prevention venting of dust explosion plate, including connection
Bar, L-type fixed frame, spring and protective net, the second composite plate right side quadrangle are mounted on connecting rod, assemble in connecting rod
There is L-type fixed frame, protective net is provided on L-type fixed frame, L-type fixed frame both passes through protective net, and protective net right end is equipped with four
A spring, protective net right end are connected by spring with L-type fixed frame.
It is broken in fire prevention venting of dust explosion plate explosion time to occur for the utility model mainly by the way that protective net is arranged in fire prevention venting of dust explosion plate side
Piece will receive the blocking isolation of protective net, so that surrounding population be made to escape injury.But the utility model is quick-fried in fire prevention venting of dust explosion plate
When fried, the first composite plate, the second composite plate can be burst, and since protective net is fixed in the second composite plate, prevent
Protective net easily generation paralysis when the second composite plate is burst is bad, and protective net is caused to fall, and cannot form lattice to the fragment for bursting generation
Gear effect, whole protection effect are poor.In addition, good soundproof effect is not present in the fire prevention venting of dust explosion plate, noise pollution is serious.
Utility model content
The purpose of this utility model is that: it solves fire prevention venting of dust explosion plate in the prior art and is difficult to be difficult to when sound insulation and explosion generation
The problem of good protection is formed to fragment, provide one kind can noise reduction and to the better noise reduction of fragment protective effect prevent fires venting of dust explosion
Plate.
The technical solution adopted in the utility model is as follows:
A kind of noise reduction fire prevention venting of dust explosion plate, including the first plate body and the second plate body arranged side by side, the first plate body side is equal
Even to be equipped with multiple groups bloop, bloop one end is into sound mouth, and the bloop other end is sound mouth, and the first plate body and the second plate body exist
It is equipped with protection acoustic damping mesh far from the side for entering sound mouth, protection acoustic damping mesh includes the stratum reticulare being stacked, the aperture of adjacent stratum reticulare
Shift to install；The upper and lower ends of first plate body and the second plate body are additionally provided with mounting plate, and protection acoustic damping mesh upper and lower ends are fixed
On a mounting board.
Wherein, the aperture for protecting each stratum reticulare on acoustic damping mesh is in regular hexagon setting.
Wherein, bloop is in the silencers channel for entering to be equipped with crippling between sound mouth and sound mouth.
Wherein, the aperture for entering sound mouth is less than the aperture of sound mouth.
Wherein, the second plate body includes close to the poroid noise reduction layer of the second stacking of the first plate body side setting and far from first
The solid venting of dust explosion layer of plate body side setting, the second poroid noise reduction layer of stacking is provided with the aperture that adjacent plane shifts to install, solid
Venting of dust explosion layer is filled with fibre reinforced cement.
Wherein, the first plate body is fireproof foam board, and the first plate body is equipped with poroid with the second stacking close to the second plate body side
The poroid noise reduction layer of the identical first cascade of noise reduction layer set-up mode.
Wherein, mounting plate is " F " template, is set on mounting plate there are two protrusion, and the second plate body is installed between two protrusions,
First plate body is Nian Jie with mounting plate by seccotine.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1, in the utility model, by the way that bloop is arranged on the first plate body, sound passes through after entering the bloop
Sound mouth outflow, and sound through protection acoustic damping mesh when due to staggeredly superposition stratum reticulare in propagate, energy is lost, into
And reach certain erasure effect, and acoustic damping mesh is protected to be equipped with two groups, explosion time is occurring, the second plate body or the first plate body are quick-fried
The fried fragment generated can obtain good lattice gear, so that whole protective performance be made to be enhanced well.On the other hand, should
Fire prevention venting of dust explosion plate mounting plate when being installed on wall perhaps roof is affixed to wall or roof, occurs in explosion
Shi Buhui is burst, therefore it can ensure that paralysis will not occur for protection acoustic damping mesh break down to fall, so that it is whole to improve fire prevention venting of dust explosion plate
Safety.
2, in the utility model, by the way that silencers channel is arranged, so that sound energy in bloop is consumed as far as possible,
To enhance whole erasure effect, the aperture additionally by setting sound mouth is greater than the aperture into sound mouth, facilitates acoustic energy
Preferably diffusion, convenient for being consumed well to it.
3, in the utility model, pass through the poroid noise reduction layer of setting first cascade, the second poroid noise reduction layer of stacking, so that
Its energy available further consumption when sound comes out and enters in the second plate body from the first plate body respectively, thus more
Whole erasure effect is further enhanced, while entirety becomes more light and handy, is easily portable, and is filled in solid venting of dust explosion layer fine
Dimension enhancing cement makes overall structure more stable.
It 4, is " F " template by setting mounting plate, the second plate body card sets two protrusions with mounting plate in the utility model
Between, stability is stronger, and the first plate body is bonded on a mounting board by seccotine, and multiple faces are bonded, and whole is steady
It is qualitative to be further enhanced.
