Horizontal-doorframe fireproof door with embedded expansion sealing strip

Abstract

The invention aims to provide a horizontal-doorframe fireproof door with an embedded expansion sealing strip. According to the technical scheme, the horizontal-doorframe fireproof door comprises a fireproof doorframe, a fireproof door body, an auxiliary fireproof door, a fireproof lock, a fireproof door closing device and a plurality of fireproof hinges. A fireproof peephole is further formed in the fireproof door body. The fireproof lock is provided with a fireproof door handle, a safety door pin and a key hole. The expansion sealing strip is disposed inside the fireproof doorframe. The horizontal-doorframe fireproof door has the advantages that the horizontal doorframe of the fireproof door can effectively block toxic and harmful gases and smoke and impurity such micro particles which are generated in fire so as to protect people taking refuge to escape safely and prevent fire spreading; the wood-board fireproof door does not need painting, paint pollution is avoided, and the fireproof door is high in hardness, resistant to aging, firm, less prone to deformation, good in sound and heat insulation effect, non-toxic, odorless, and economical and practical; safe people evacuation is powerfully guaranteed, and fire spreading can be delayed for a long time.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a horizontal door frame fire door with a pre-embedded expansion sealing strip. Background technique [0002] In the past, fire doors used metal materials as the main material of fire doors, which were relatively heavy and inconvenient to use. The horizontal door frame of the fire door can effectively block the fire and the toxic and harmful gases, smoke, particles and other impurities produced in the fire, so as to protect the refugees from escaping safely and block the spread of the fire. The wooden board fire door does not need to be painted, avoids paint pollution, saves costs, and has high hardness and anti-aging; it is moth-proof, moisture-proof, anti-fouling, heat-resistant, crack-resistant, strong and not easily deformed, and has good sound and heat insulation effects; Toxic and tasteless, free of formaldehyde and toluene, no radiation pollution, environm...
