Description

Smoke-proof, fire-proof and theft-proof safety door

Technical Field

The utility model relates to an emergency exit, concretely relates to smoke prevention fire prevention theftproof emergency exit of registering one's residence.

Background

A fire door is a door that can meet the requirements of fire stability, integrity and thermal insulation within a certain period of time. It is a fire-proof partition with certain fire resistance, which is arranged in fire-proof subareas, evacuation staircases, vertical shafts and the like.

At present, in order to protect personal safety and property safety of people, high-rise buildings are required to use fireproof doors in China. However, most fireproof doors in the current market are not smoke-proof and theft-proof, and more than 60% of fatalities of a fire are caused by smoke. Because: 1) in order to ensure that flame does not jump, a fireproof door is simplified in terms of burglary prevention (lock points (including lock tongues, explosion-proof bolts and the like) are fewer), 2) a static smoke prevention function conflicts with air tightness, if the air tightness is too high, indoor air cannot circulate, and if the air tightness is too low, the smoke prevention function cannot be realized; 3) dynamic smoke protection (when the door is burned), the seal itself may burn creating toxic smoke or the smoke protection may be lost due to high temperature induced distortion.

The specific implementation mode is as follows:

the following describes the embodiments of the present invention in detail.

As shown in fig. 1 to 3, the smoke-proof, fire-proof and theft-proof entrance safety door comprises:

a door frame 11;

two door leaves 10, the upper and lower part of its first side link to each other with door frame 11 through hinge 8 respectively, and the second side of two door leaves 10 passes through latch structure 12 and links to each other, wherein:

the door leaf 10 is sequentially provided with an outer decorative plate 13, a fireproof plate 6, an outer steel plate 16, a door core plate 5, an inner steel plate 15 and an inner decorative plate 14 from outside to inside;
