WIPO Patent Application WO/2019/203415
Kind Code:
A1
Abstract:
The present invention relates to a fire-rated double door and, more specifically, to a device for preventing the deformation of a fire-rated double door, the device minimizing the expansion and deformation of the fire-rated double door, caused by heat during a fire, so as to prevent the separation of hinges therefrom and the spreading of flame or smoke. According to the present invention devised in order to solve a technical objective, a device for preventing the deformation of a fire-rated double door having a right door and a left door rotating 180 degrees on both sides comprises: rotating members, which have hinge shafts provided at both ends of the fire-rated double door and hinges connected to the inner sides of the hinge shafts and embedded in the fire-rated double door, so as to rotate the fire-rated double door around the hinge shafts; frame members, which are provided on the rear surfaces of the hinge shafts, have one side embedded in a wall and have, on the other sides thereof, fixing bent parts having bent grooves, so as to extend in a vertical direction; and stopper members, which are provided on the rear surfaces of the fire-rated double door and have, on one side surface of each, partially protruding protrusion parts inserted into the fixing bent parts such that the hinges are prevented from being separated, because of the deformation of the fire-rated double door, from the fire-rated double door if a fire breaks out.
