Fire door with strong aseismic capability

Abstract

The invention discloses a fire door with a strong aseismic capability, including a doorframe. The right side of the internal part of the doorframe is connected with the fire door through a hinge. Theexternal parts of installation bolts are connected with shockproof springs in sleeve. The front and rear parts of the fire door are provided with first protective steel plates. The inner sides of thefirst protective steel plates are provided with fireproof layers. The inner sides of the fireproof layers are provided with second protective steel plates. A reinforcing steel plate is arranged between the second protective steel plates. The doorframe of the fire door with the strong aseismic capability is firmly fixed when the doorframe passes the installation bolts arranged in the internal partof an installation hole and is fixed with a wall body. Through the setting of the external part of the installation bolts connected with the shockproof springs in sleeve, the fire door is provided with the aseismic capacity. Through the setting of the first protective steel plates, the fireproof layers and the second protective steel plates, the structural strength of the fire door is enhanced andmeanwhile the fireproof ability of the fire door is also enhanced. Through the setting that the reinforcing steel plate is centered in an inner cavity of the fire door, the structural strength of thefire door is enhanced.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a fire door with strong earthquake resistance. 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. Higher conditions are prone to warping, bending and other deformations, resulting in gaps between the main body of the fire door and the fire door frame, and flames or thick smoke are easy to escape from the gaps, thereby reducing the safety protection performance, and the fire prevention effect is poor. Accidents occur, for this reason, we have introduced a fire door with strong earthquake resistance. Contents of the invention [0003] The purpose of the present invention is to provide a fire door with strong earthquake resistance, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, t...
