The utility model relates to the technical field of door and window structures, in particular to a novel fireproof partition door and window structure. Comprising a window frame and a door frame which are fixedly connected, a fireproof door is rotationally arranged in the door frame, a door lock is fixedly arranged on the fireproof door, fireproof glass is arranged in the window frame, a containing groove is formed in the window frame, a fireproof expansion layer fixedly connected to the window frame is arranged on the edge of the containing groove, and the fireproof glass is installed in the containing groove. According to the fireproof door and window frame, the fireproof expansion layer is arranged in the containing groove, the fireproof expansion layer rapidly expands to form a compact carbonization layer when meeting fire, tiny gaps (smaller than or equal to 1 mm) between the door and window frame and the glass and between the door and window frame and the door plate are filled, permeation paths of flames, high-temperature gas (larger than or equal to 300 DEG C) and toxic smoke are blocked, the fire spreading time is prolonged to 90 minutes or above, and therefore the technical problem is solved.
