Fireproof door with good heat insulation performance

Abstract

The invention discloses a fireproof door with good heat insulation performance. The fireproof door comprises a fireproof door body, a fireproof door frame, fireproof door columns and a bottom groove;the fireproof door frame is movably connected to the top of the fireproof door body, the fireproof door columns are fixedly connected to the bottom of the fireproof door frame, and the bottom groove is fixedly connected to the fireproof door columns; the fireproof door body comprises a rubber layer, a heat insulation layer, movable wheels, sound insulation layers, one-way see-through glass and handles; the one-way see-through glass is embedded in the middle of the fireproof door body, the handles are fixedly connected to the left sides of the front and rear ends of the fireproof door body, therubber layer is fixedly connected to the middle of the fireproof door body, the sound insulation layers are fixedly connected to the left side of the rubber layer, the heat insulation layer is fixedly connected to the right side of the rubber layer, and the movable wheels are fixedly connected to the bottom of the heat insulation layer; sliding grooves are embedded in the top of the bottom groove. The whole fireproof door is stable in structure and convenient to close and open, can be used for viewing a visitor, and has good fireproof capability, a good sound insulation effect and high popularization value.

Description

technical field [0001] The invention relates to the technical field of fire door processing and manufacturing, in particular to a fire door. 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. The equipment room (steel cylinder room, foam station, etc.) of the fixed fire extinguishing device in the high-rise civil building, the partition wall door of the ventilation and air conditioning machine room, etc. shall adopt Class A fire doors; The upper door should be a Class A fire door; due to limited conditions, it is necessary to arrange fuel and gas boilers, fuel oil-immersed power transformers, high-voltage capacitors and switches filled with combustible fuel, and special room partition walls in high-rise buildings. The upper doors should be Class A fire doors, and there are also doors with special design requirements that must be fireproof, such as fire moni...
