Description
Technical field
The present invention relates to the field of building materials, and in particular to a kind of orientation venting of dust explosion plate and preparation method thereof.
Background technique
Currently, existing structures several greatly there is no pressure-relief explosion-proof facility absolutely, even storage combustible and explosive articles
Warehouse either produce combustible and explosive articles workshop, be also all not provided with dedicated pressure-relief explosion-proof facility, therefore once change
The property learned or physical explosion, the explosion including fuel gas, dust and mixed gases can generate powerful impact moment
Blast destroys building and surrounding property, causes to cause huge economic loss and casualties, so, in this case,
It is necessary to take positive Initiative Defense measure.Moreover, with the enhancing of people's anti-explosion safety idea, people increasingly realize
To the importance that pressure-relief explosion-proof facility is arranged on building, to ensure to obtain maximum explosion-proof effect with the smallest loss.
In the prior art, Chinese patent literature CN201110414Y discloses a kind of suitable for using on wall and roof
Explosion venting device by venting of dust explosion plate, venting of dust explosion bolt, traction strand cable and is fixedly mounted component and forms, venting of dust explosion plate by moderate soak rock wool and
Double-layer sandwich sheet metal made of ectonexine pressing metal plates is filled the post of, and ectonexine metal plate is selected inside and outside with building masonry wall
The sheet metal that surface shape is consistent is filled the post of, and venting of dust explosion bolt is filled the post of by the venting of dust explosion special bolt that ultimate strength is 20psf, in addition matches
It equipped with special (purpose) rubber set, draws and is provided with assembly ring set on the end of strand cable, fixed installation part is filled by main body in " C " shape wingceltis item
Appoint, in use, the form that a part that venting of dust explosion plate can be used as wall is arranged in the form of monolithic or muti-piece splices on demand is closely
Setting, constitutes biggish venting of dust explosion region, and when room pressure is close to 20psf, the i.e. automatic fracture of venting of dust explosion bolt falls off, drives and let out
The at once automatic bullet outward of plate bursting flies, and pressure relief opening is quickly formed on building, the impact wave for formation of exploding can be through pressure relief opening
Release outward, the destructive power for causing indoor explosion are preferably minimized, and the effect of contraction due to drawing strand cable, and venting of dust explosion plate will not fly
Splash it is separate, injure pedestrian or property around building.The venting of dust explosion plate of the explosion venting device can play corresponding venting of dust explosion effect, but
It is that, since the venting of dust explosion plate must be used cooperatively with component is fixedly mounted, after explosion occurs, venting of dust explosion plate can be integrally detached from
Position originally, there is no load-bearing effects for the venting of dust explosion plate itself, it is necessary to be used in combination with the structural slab with weight-bearing function.
