Alarm type fire proof door with high fire resistance

Abstract

The invention relates to the technical field of fire fighting equipment, and discloses an alarm type fire proof door with high fire resistance. The alarm type fire proof door with the high fire resistance comprises a fire proof door body, a door lock fixedly installed in the middle of one side of the fire proof door body and a door closer fixedly installed at the top of the fire proof door body. Aheat absorption tank is formed in the inner bottom of the fire proof door body, the heat absorption tank is filled with non-combustible liquid heated to produce gas under atmospheric pressure, a plurality of supporting rods are arranged in the heat absorption tank, a vertical gas guide pipe is arranged at the position, located above the heat absorption tank, in the fire proof door body, and a horizontal jet groove is formed in the position, located above the air guide pipe, of an inner cavity of the fire proof door body. According to the alarm type fire proof door with the high fire resistance, by forming the heat absorption tank at the inner bottom of the fire proof door body and filling the heat absorption tank with the non-combustible liquid heated to produce the gas, the bottom of thedoor can be heated and vaporized to have heat absorption performance when a fire occurs, the fire resistance duration can be prolonged on the basis of existing fire proof door materials, and the fireresistance of the fire proof door can be improved effectively.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to an alarm type fire door with high fire resistance. Background technique [0002] In daily life, fire doors are required for closed evacuation stairs, closed elevator rooms leading to the front room and doors leading to the aisle from the front room, firewalls set up to control the building area of ​​fire compartments and doors on fire partition walls, etc. In addition to the function of ordinary doors, it also has the function of preventing the spread of fire and smoke. It can prevent the spread of fire within a certain period of time and ensure the evacuation of personnel. Therefore, fire doors are required to meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. [0003] At present, most of the sources of fire originate from the ground (the plane where the fire door is located), and the corresponding ...
