Fireproof door with triple fireproof function

Abstract

The invention discloses a fireproof door with a triple fireproof function. The fireproof door comprises a fire-resisting door frame and a main fireproof door body; water tanks are arranged at the twoends of the upper portion of the fire-resisting door frame, and firefighting spraying heads are mounted below the water tanks; door spindles are sequentially fixed to the inner side of the fire-resisting door frame, fireproof shells are arranged at the front end and the rear end of the main fireproof door body, rolling wheels are fixed to the upper end and the lower end of the interior of each fireproof shell, and sliding fire-resisting doors are arranged between the rolling wheels; and the sliding fire-resisting doors are stored in the fireproof shells, anti-collision protruding blocks are mounted on the outer surfaces of the fireproof shells, pulling handles are arranged on the outer sides of the sliding fire-resisting doors, and a fire-resisting plate is arranged in the main fireproof door body. According to the fireproof door with the triple fireproof function, a three-layer fireproof structure is formed by the mounted main fireproof door body and the fireproof shells at the frontend and the rear end of the main fireproof door body, erosion of the fire behavior on the main fireproof door body can be weakened under blocking of the fireproof shells, and thus the fire-resisting performance of the fireproof door with the triple fireproof function 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] A fire door is a door that has a certain fire resistance, can prevent the spread of fire and smoke, and can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. Fire doors are generally located in fire compartments, evacuation Stairwells, vertical shafts, etc. [0003] The structure size of the existing fire doors is often fixed. When the fire spreads and the fire range expands, the flames are easy to invade from both sides of the fire door. However, the existing fire doors cannot adjust their protection range in time as the fire spreads. If the protection is not in place, the trapped people are still in a more dangerous environment. Contents of the invention [0004] The object of the present invention is to provide a triple fireproof fire door, to solve th...
