Anti-thermal-radiation fireproof door

Abstract

The invention provides an anti-thermal-radiation fireproof door. According to the scheme, the anti-thermal-radiation fireproof door comprises a door body, wherein three chambers are arranged in the door body; push-pull glass having fireproof performance is arranged in the first chamber; the push-pull glass slides along a push-pull track; a cooling device is arranged in the second chamber; a plurality of assembled fireproof door core boards are arranged in the third chamber; a fireproof frame capable of allowing a normal adult to pass upright is further arranged on the door body; the fireproofframe penetrates through the door body and is sealed at a joint with the three chambers; the length and the width of the push-pull glass are larger than the fireproof frame and can block the fireproofframe to replace the fireproof glass after the push-pull glass is pushed for a certain distance; and a knocking hammer for crushing the fireproof glass is further arranged on the door body. Accordingto the anti-thermal-radiation fireproof door, the problems that the fireproof door is poor in fireproof and heat insulation effects and difficult to open in danger and has no thermal radiation prevention in the prior art are solved.

Description

Technical field [0001] The invention relates to the field of fire-fighting equipment, in particular to a heat-radiation-proof fire-proof door. Background technique [0002] Fire doors usually refer to doors located in some enclosed places such as stair walkways, elevator rooms, cable shafts, flue gas ducts, etc. The function of fire doors is to meet the fire resistance stability within a certain period of time, with good heat insulation, and can prevent The spread and spread of fire and heat radiation. [0003] However, most of the existing fire doors on the market are filled with various fireproof materials and compacted to achieve the effect of fire and heat insulation. However, the effect of fire protection and heat insulation of this kind of fire door is poor. It is difficult to produce a good fire protection effect during a fire; in addition, a solid fire door not only wastes materials, but also increases the weight of the fire door, which not only brings a lot of inconvenien...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the deficiencies in the above-mentioned prior art, the present invention provides a heat-radiation-proof fireproof door to solve the problems in the prior art that the fireproof door has poor fireproof and heat insulation effects, is difficult to open at a critical moment, and does not have heat radiation protection.
