Fabricated fireproof and anti-explosion composite plate

Abstract

The invention discloses a fabricated fireproof and anti-explosion composite plate. The composite plate comprises a first metal plate, a second metal plate and an intermediate layer, wherein one intermediate layer is arranged between the first metal plate and the second metal plate, the intermediate layer, the first metal plate and the second metal plate are fixed through a reinforcing connecting piece, the reinforcing connecting piece penetrates through the intermediate layer, the first metal plate and the second metal plate to form the detachable composite plate, and the intermediate layer comprises a fireproof plate with a fireproof function. Compared with the prior art, the fireproof and anti-explosion composite plate has the advantages of being convenient to install and disassemble andcapable of ensuring attractive appearance and convenient transportation by adopting the fabricated stamping-free type fixing, and meanwhile adopting the fabricated type to ensure that the surface ofthe fireproof and anti-explosion composite plate is flat, thereby effectively ensuring the fireproof and anti-explosion effect.

Description

technical field [0001] This patent relates to the field of engineering structure protection, in particular to an assembled fire-resistant and anti-explosion composite board for fire-proof and anti-explosion walls or suspended ceilings. Background technique [0002] From the high-tech semiconductor industry to the coal petrochemical industry and even to the ordinary manufacturing industry, they all have in common the need to protect buildings. If the damage caused by the explosion is controlled within a minimum range, the damage caused by it will also be inevitable. To minimize, most buildings need to be equipped with walls with explosion-proof function or flame-retardant function. [0003] At present, the commonly used measures on the market are anti-explosion panels produced by stamping technology. Among them, the patent with the authorized announcement number of CN204491985U discloses an anti-shock and explosion-proof panel, which is arranged on both sides of the fireproof...

AI Technical Summary

Problems solved by technology

[0005] The fireproof and explosion-resistant composite panels in the prior art have at least the following defects: (1) The fireproof and explosion-resistant composite panels in the prior art usually rely on galvanized steel sheets and the cement layer in the middle by stamping, and the cement layer is designed to strengthen the connection However, the design structure is relatively complicated, and the manufacturing and installation steps are complicated; (2) the existing fire-proof and explosion-resistant composite panels are fixed by welding, steel plate stamping, etc., which is easy to cause explosion-proof panels. Surface pits affect anti-blast and fireproof effects; (3) Existing anti-blast panels are physically bonded by punching, which requires a fixed mold during production, and it is not suitable to cut after production, which will easily lead to anti-blast. The bursting plate breaks and destroys the effect of the anti-explosive plate. It cannot be cut according to the actual size of the follow-up, resulting in unnecessary waste
