A fireproof door with triple protection functions

Abstract

The invention discloses a fireproof door with triple protection functions. The fireproof door comprises a fireproof door frame and a main fireproof door. Water tanks are arranged at the two ends of the upper portion of the fireproof door frame, fire-fighting spraying heads are mounted below the water tanks; door shafts are sequentially fixed on the inner side of the fireproof door frame; fireproofshells are arranged at the front end and the rear end of the main fireproof door; rollers are fixed to the upper end and the lower end of the interior of each fireproof shell, a push-pull fire-retardant door is arranged between the rollers, the push-pull fire-retardant door is arranged in each fireproof shell, an anti-collision lug is arranged on the outer surface of each fireproof shell, a handle is arranged on the outer side of each push-pull fire-retardant door, and a flame-retardant plate is arranged in the main fireproof door. The main fireproof door installed on the fireproof door withtriple protection functions and the fireproof shells at the front end and the rear end of the main fireproof door form a three-layer fireproof structure, fire can that causes damage to the main fireproof door is weakened under blocking of the fireproof shells, and therefore the fire retardance of the fireproof door with triple protection functions is improved.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a triple fireproof door. Background technique [0002] Smoke doors, also known as fire doors, are doors used to maintain the fire-resistant integrity of the fire escape and provide a means of escape. The purpose is to ensure that people who are escaping in the fire escape are protected from the threat of fire within a reasonable period of time. , including blocking dense smoke and heat, can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. It is a fire partition with certain fire resistance in fire compartments, evacuation stairwells, vertical shafts, etc., In addition to the function of ordinary doors, fire doors also have 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 people. [0003] The structure size of ...
