[0021] Please refer to Figures 1 to 5 , a combined vertical member system of a fire door with columns and a fire shutter, including a fire shutter device 1, a fire door device 2, and a column frame 3 arranged between the fire shutter device 1 and the fire door device 2. The fire shutter device 1 includes a shutter box body 31 arranged on the top of the column frame 3, a shutter guide rail 32 installed on the column frame 3, a rolling door machine 33 arranged in the shutter box body 31, a reel 34 axially connected to the rolling door machine 33, and a shutter board 35 wound on the reel 34. The rolling door machine 33 controls the lifting and lowering of the shutter board 35 in the shutter guide rail 32 through the reel 34. The fire door device 2 includes a storage frame 21 installed in the wall body 100, a door frame 22 installed on the other side of the column frame 3 relative to the shutter guide rail 32, and a door leaf 23 hinged to the storage frame 21. A magnetic lock 4 for controlling the opening and closing of the door leaf 23 is arranged in the storage frame 21. The fire shutter device 1 can adopt a steel fire shutter or an inorganic cloth fire shutter to ensure the fire prevention effect. The fire door device 2 adopts a concealed normally open fire door with the door leaf 23 that can be stored in the wall body 100. Usually, the fire shutter device 1 is stored on the top of the column frame 3, generally at the ceiling.
