Abstract
The present invention relates to a pressure relief plate used for buildings which have explosion danger due to combustible gas, such as methane, natural gas, propane, liquefied petroleum gas, etc. Pressure of various concentrations including the most dangerous concentration, which can generate explosion in the buildings, is reduced to 10 kilopascals at most, and the main structure of the buildings are not damaged, so human and property loss is reduced.
Description
The present invention relates to a kind of centre has the purposes of the fire-retardant decompression plate in cellular or corrugated space, in the building of flammable gas explosion danger such as it is used to that methane is arranged, propane, natural gas, liquefied petroleum gas, uses as blast pressure release decompression plate.
For methane, propane, natural gas, liquefied petroleum gas and characterisitic parameter K are arranged
G* maximum value is less than 8000(kPa of rice second
-1) the building of fuel gas, general by " building fire protection standard " design relief hole.But under dangerous combustable gas concentration, still exist and very high can cause the quick-fried of building main component to ruin, in this class building, install " decompression plate " of the present invention by sound " the 3rd pressure spike " that standing wave excites of shaking.When blasting, will eliminate the generation of " the 3rd pressure spike ", blast pressure is reduced within 10 kPas, the protection constructure body structure does not go to pot, thereby alleviates people and property's loss.
The characteristics of this " decompression plate " are to can be single or multiple lift, and the centre has cellular or the corrugated space, and through hole is arranged.The material of " decompression plate " can be selected fire-retardant packing board, plastic plate, rubber tile or cork slab." decompression plate " is attached on the inwall of building in a certain way, and can there be ornamental floral designs on its surface.
