Steel thermal insulation fireproof door

Abstract

The invention discloses a steel thermal insulation fireproof door. The steel thermal insulation fireproof door comprises a lower door frame, a smoke alarm, a fireproof thermal insulation board and a thermal insulation fireproof perspective window, a first side door frame is arranged on one side above the lower door frame, a water pipe through hole is formed in the upper end of the first side doorframe in a molding mode, and a water inlet hose is arranged in the water pipe through hole. The steel thermal insulation fireproof door has the beneficial effects that through the arrangement of a door frame fireproof expanded sealing strip and a door body fireproof expanded sealing strip, the sealing performance of the thermal insulation fireproof door can be improved, and smoke is prevented fromseeping through a door slot in case of fire and from causing potential safety hazards to escape personnel; through the arrangement of the water inlet hose, a water inlet valve, a water inlet telescopic pipe, a water tank and a water spray pipe, it is ensured that water is sprayed out through the water spray pipe in case of fire, the temperature of a fireproof door leaf and surrounding is effectively reduced, and the thermal insulation fireproof performance of the fireproof door leaf is improved; and through the arrangement of the smoke alarm and the smoke sensor, an alarm can be given for thefirst time in case of fire, and the rescue time is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of fire doors, and the invention relates to a steel heat-insulating fire door. Background technique [0002] With the continuous development of the construction industry, the manufacturing technology of doors and windows is also constantly developing. The quality of doors and windows and the structural applicability of doors and windows have become the main factors. For doors and windows in some public places, such as studios, rehearsal venues, theaters, cinemas, Indoor sports venues, dance halls, KTV rooms and other places often require the doors and windows in these areas to have good heat insulation and fireproof performance to provide a strong guarantee for people's safety. The heat-insulated fire doors are mainly used to maintain the fire-resistant integrity of the fire escape. The purpose is to ensure that the people who are escaping in the fire escape are protected from the threat of fire during the s...

[0002] With the continuous development of the construction industry, the manufacturing technology of doors and windows is also constantly developing. The quality of doors and windows and the structural applicability of doors and windows have become the main factors. For doors and windows in some public places, such as studios, rehearsal venues, theaters, cinemas, Indoor sports venues, dance halls, KTV rooms and other places often require the doors and windows in these areas to have good heat insulation and fireproof performance to provide a strong guarantee for people's safety. The heat-insulated fire doors are mainly used to maintain the fire-resistant integrity of the fire escape. The purpose is to ensure that the people who are escaping in the fire escape are protected from the threat of fire during the safe escape time, including blocking smoke and heat. The current fire doors can escape safely. However, the sealing performance between the door body and the door frame, and the door frame and the wall body is not very good, and the smoke will still seep out from the gap. In addition, when a fire occurs, the temperature of the door body and the surrounding area will rise rapidly, which is safe. Hidden dangers, when a fire occurs at the same time, the alarm cannot be issued in time, and the rescue time will be delayed
