Efficient flame-retardant smoke-isolating fireproof door

Abstract

The invention discloses an efficient flame-retardant smoke-isolation fireproof door. The efficient flame-retardant smoke-isolation fireproof door comprises a fireproof door body, the fireproof door body comprises a fireproof core plate, a fireproof outer plate is arranged outside the fireproof core plate, a gas storage cavity and a liquid storage cavity which are isolated through a first isolationfilm are sequentially distributed in the fireproof core plate from bottom to top, the gas storage cavity is filled with inert gas, and the liquid storage cavity is filled with cooling liquid; a gas outlet groove, an evaporation cavity and a liquid outlet groove are sequentially formed in the fireproof outer plate from bottom to top, the gas outlet groove communicates with the gas storage cavity,a first sealing plate is arranged in the gas outlet groove, the liquid outlet groove communicates with the liquid storage cavity, a second sealing plate is arranged in the liquid outlet groove, the evaporation cavity is located on the outer sides of the gas storage cavity and the liquid storage cavity and communicates with the gas outlet groove, and evaporation liquid is arranged in the evaporation cavity. The efficient flame-retardant smoke-isolation fireproof door has the characteristics that smoke dust is effectively blocked, the temperature and the fire behavior of the fireproof door are reduced, and help to escape personnel is enhanced.

Description

technical field [0001] The invention relates to a safe fire door structure, in particular to a high-efficiency flame-retardant and smoke-insulating fire door. Background technique [0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time, and are generally installed in closed evacuation stairs, leading to aisles, etc. Fire doors play a certain role in gaining time for people to escape from the fire and preventing the spread and spread of the fire. They are an important part of the equipment in the fire fighting equipment. The existing fire doors generally only play the role of blocking the fire. There are many gaps between the fire door body and the door frame. The temperature itself will rise quickly, and the heat insulation performance is not good. If the escape personnel or rescue personnel come into contact with the fire door, they will easily cause burns. The door panel...

AI Technical Summary

Problems solved by technology

The existing fire doors generally only play the role of blocking the fire. There are many gaps between the fire door body and the door frame. The temperature itself will rise quickly, and the heat insulation performance is not good. If the escape personnel or rescue personnel come into contact with the fire door, they will easily cause burns. The door panel is carbonized after burning. Although it can prevent the fire from spreading within a certain period of time, the flame will always be attached to the door panel and will continue to burn. The acquisition time is not long, and the help to escapers is limited

[0003] Therefore, the existing fire doors have the disadvantages of easy diffusion of smoke, general effect of blocking high temperature and fire, and limited help to escape personnel.
