When installing this fireproof board, after inserting bolts into the grooves 6 and the reserved holes 5, the bolts are fixedly connected to the skeleton on the smoke and ventilation conveying pipes, avoiding on-site drilling operations on the board body and improving the efficiency of fireproof board installation.

[0027] In addition, by installing the thermal insulation layer 1, the warm air or cold air inside the ventilation and conveying duct is prevented from being exposed, thereby improving the thermal insulation effect of the ventilation and conveying duct.

[0028] At the joint of two fireproof boards, the traditional method is to first apply sealant on the surface of the galvanized board, then cover the gap between the two fireproof boards with the side of the galvanized board coated with sealant, and finally use screws to fix the galvanized board and the two fireproof boards to complete the connection between the two fireproof boards. Obviously, this connection method is time-consuming and labor-intensive, and is not conducive to the rapid installation of the fireproof boards. Therefore, the utility model is provided with a clamping assembly on the board body, and the clamping assembly includes a plug rod 7, which is fixedly arranged on one side of the board body, and a connecting groove 9 is provided on the other side of the board body, which is located inside the fireproof layer 4.

There are two connecting grooves 9 and two insertion rods 7, and the two insertion rods 7 are symmetrically distributed about the center line of the board body.
