s1: when the fireproof door body (4) and the placing frame (1) need to be spliced together, the placing frame (1) is placed on the upper side of the fireproof door body (4), and meanwhile, a first strip-shaped through hole (106) and a first gear hole (105) in the placing frame (1) are aligned to a second strip-shaped through hole (302) and a second gear hole (301) in the door frame (3);
s2: the clamping rod (8), the strip-shaped clamping block (802) and the rubber tooth block (801) penetrate through the first strip-shaped through hole, the first gear hole (105) and the moving interface (703), then the strip-shaped clamping block (802) on the clamping rod (8) is located above the locking plate (7), then the single rotary column (902) is rotated, then the single rotary column (902) drives the connecting rotary plates (903) on two sides to adjust up and down, meanwhile, the double rotary columns (901) are driven to rotate for 90 degrees, further the connecting rod (9), the rubber tooth block (801), the clamping rod (8) and the strip-shaped clamping block (802) are sequentially driven to rotate for 90 degrees, then the strip-shaped clamping block (802) can rotate to the position of the strip-shaped clamping opening (701) on the upper side of the locking plate (7), at the moment, the pulling plate (5) is loosened, therefore, the spring (10) pushes the pulling plate (5) to move downwards, the strip-shaped clamping block (802) is clamped into the strip-shaped clamping opening (701), and at the door frame (3) and the placing frame (1) are placed together;
s3: after the fireproof door body (4) and the placing frame (1) are installed and fixed at an indoor doorway, an external water pipe passes through the connecting hole (104) and is connected to the flow dividing pipe (6), and the electromagnetic valve (601) is in a closed state, so that water is blocked in the external water pipe;
s4: when an indoor fire disaster occurs, the fire can extend to the position near a fire door along the same way, so that generated smoke is sensed by the smoke sensor (107), the electromagnetic valve (601) is opened, the shunt pipe (6) is communicated with an external water pipe, water is sprayed out by the spray head (2) at the shunt pipe (6), and the fire near the fire door body (4) can be extinguished by the sprayed water.
