Steel fireproof door capable of enhancing fire integrity

Abstract

The invention relates to the technical field of fireproof doors, and particularly relates to a steel fireproof door capable of enhancing fire integrity. The steel fireproof door comprises a door body, wherein a handle is arranged on the end face of the door body, the door body comprises two steel plates, a first fireproof layer and a second fireproof layer, the first fireproof layer and the second fireproof layer are arranged between the two steel plates, and fixing parts are arranged at the tops and the bottoms of opposite end faces of the two steel plates at intervals. According to the steel fireproof door capable of enhancing fire integrity, an external fire source can be primarily blocked by fireproof coatings arranged on the steel plates, second inorganic refractory mortar is solidified when heated, so that reinforcing ribs are prevented from deforming at high temperature and can stably support and connect the first fireproof layer and the steel plates, the two steel plates are not easily separated, fire integrity of the door body is enhanced, hollow glass can function in smoke and heat insulation, and a glass magnesium board is high in density and good in fireproof performance.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a steel fire door with enhanced fire-resistant integrity. Background technique [0002] Fire doors refer to doors that can meet the requirements of fire resistance, integrity and heat insulation within a certain period of time. For example: the equipment room (steel cylinder room, foam station, etc.) of the fixed fire extinguishing device attached to the high-rise civil building, the partition door of the ventilation and air conditioning machine room, etc. should adopt Class A fire doors; The door on the partition wall of the basement room shall be a Class A fire door; due to limited conditions, fuel and gas boilers, fuel oil-immersed power transformers, high-voltage capacitors and switches filled with combustible fuel must be arranged in high-rise buildings. [0003] Existing fire doors usually strengthen the strength of the door body by installing reinforcing ribs on the to...
