[0008] Both sides of the bottom plate of the third fireproof plate are provided with a semicircular arc and a connecting hole, and the two side plates of the third fireproof plate are both provided with a connecting hole;

[0009] One side of the first fireproof plate and the third fireproof plate is connected through the connecting lug, the connecting hole and the bolt, and the other side of the third fireproof plate and the second fireproof plate is connected through the connecting lug, the connecting hole and the bolt.

[0010] The two side plates of the first fireproof plate, the second fireproof plate and the third fireproof plate are connected with the metal groove box through the bolt.

[0011] The utility model discloses when installing, first fireproof board is installed at the inboard of the vertical cable bridge frame crossing floor place, and the bottom plate elevation of first fireproof board is adjusted to the bottom elevation of floor consistent, and the two side faces of first fireproof board are installed closely with the two side faces of vertical cable bridge frame, and the bolt is passed into the reserved bolt hole corresponding of the two side faces of first fireproof board and vertical cable bridge frame, and is fastened with nut, second fireproof board is close to first fireproof board, and the bottom plate elevation of two fireproof boards is consistent, and the semicircle arc and the connecting lug of second fireproof board and first fireproof board overlap, and the bolt is passed into the connecting lug of second fireproof board overlapping part, and the two side faces of second fireproof board are installed closely with the two side faces of vertical cable bridge frame, and the bolt is passed into the corresponding reserved hole and is fastened, third fireproof board is close to second fireproof board, and the bottom plate elevation of two fireproof boards is consistent, and the semicircle arc and the connecting lug of second fireproof board and third fireproof board overlap, and the bolt is passed into the connecting lug of third fireproof board, and the two side faces of third fireproof board are installed closely with the two side faces of vertical cable bridge frame, and the bolt is passed into the corresponding reserved hole and is fastened, after installing, fireproof bag or fireproof mud is placed on three fireproof boards, installs bridge cover after filling, and completes the plugging.

[0012] The utility model discloses can install among the vertical cable that lays, and fix in the inboard of vertical metal groove box crossing floor place, when the vertical cable is laid gradually, can conveniently fix the cable in the semicircle arc of first fireproof board, after the vertical cable is laid in the semicircle arc, immediately install stack third fireproof board or second fireproof board, and the semicircle arc between two adjacent fireproof boards constitutes a complete round hole (i.e. cable threading hole), place fireproof bag or fireproof mud on the fireproof board, and the filling amount is little, can keep sealed filling state permanently, will not fall off because of long -time use, solve the problem that the vertical metal groove box crossing floor place is not tight, is not durable.
