Abstract

The invention belongs to the technical field of firefighting safety, and particularly discloses a firefighting linkage normally-open fireproof door which comprises a door frame mounted on a wall, twodoor plates hinged on the door frame, a smoke sensing detector, an automatic alarming signal detector, a controller, a door closing device, an electromagnetic connection component, a buffering devicearranged in the door frame, an infrared detector and an infrared control switch. The infrared detector and the infrared control switch are arranged on the door plates, one end of the door closing device is mounted in the door frame while the other end is mounted on the door plates, the smoke sensing detector, the automatic alarming signal detector and the controller are all arranged on the wall, the electromagnetic connection component comprises a first electromagnet arranged in the wall, a magnet and an electromagnetic control switch which is in parallel connection with the infrared control switch, and the magnet and the electromagnetic control switch are arranged on the door plates and correspond to the first electromagnet. The firefighting linkage normally-open fireproof door is properin closing strength and free of pedestrian pinching.

Description

technical field [0001] The invention belongs to the technical field of fire safety, and specifically discloses a fire-fighting linkage normally open fire door. Background technique [0002] The residential core tube is the central part of the building, which is formed by elevator shafts, stairs, ventilation shafts, cable shafts, public toilets, and some equipment rooms. It forms an outer frame and inner tube structure with the peripheral frame and is poured with reinforced concrete. Fire protection requires that the fire elevators and stairs in the core of the residential building share the front room, and they need to be separated by fire doors. time for evacuation or firefighting. [0003] Ordinary fire doors are equipped with door closers, which are normally closed and have no effect. The fire elevator and stairs are separated from the common front room, which greatly affects the overall aesthetic effect of the residential core tube, and has been opened and closed many t...
