The invention relates to a large-size horizontal hinge upturning type airtight fireproof landing door which comprises a door body, a follow-up supporting rod, a door opening oil cylinder, a top hinge and a hinge base. The top of the door body is connected with the hinge base on the top of a cabin wall door frame through the top hinge. The two sides of the door body are connected with a frame of the bulkhead door frame through door opening oil cylinders correspondingly, and the door opening oil cylinders are connected with the door body and the frame of the bulkhead door frame in a hinged mode. Follow-up supporting rods are further connected between the two sides of the door body and the frame of the bulkhead door frame, one end of each follow-up supporting rod is slidably connected with a guide sliding groove in the side face of the door body in a matched mode through a guide shaft, the other end of each follow-up supporting rod is hinged to the frame of the bulkhead door frame, and a hydraulic lock pin is installed on the back face of the door body. The fireproof door can be applied to a fireproof landing door for a ship elevator, and the fireproof integrity and heat insulation performance of a whole channel and a cabin can be improved. The compression range of the flame-retardant rubber strip is large, the position of the flame-retardant rubber strip on the door body can be adjusted on site, and boarding installation is very convenient. And after being opened in place, the landing door is locked by an accompanying supporting rod of the landing door.
