Further, the mortise-and-mortise joint of the inner corner fireproof board and the adjacent inner corner fireproof board is fixed by a second steel nail.

Further, the outer corner fireproof board and the adjacent outer corner fireproof board or the outer corner fireproof board and the inner corner fireproof board are fixed by third steel nails.

Further, the keel of the fireproof board and the fireproof coating on the outside of the special-shaped column are fixed by a high temperature adhesive.

Further, the heat insulating fibers are ceramic heat insulating fibers.

The working principle of the utility model is as follows: coating a fireproof coating on the outside of the special-shaped column, bonding several parallel fireproof board keels on the outside of the fireproof coating, and then according to the shape of the special-shaped column, the outer corner fireproof board and the inner corner fireproof board are made of steel. The nails are fixed on the outside of the keel of the fireproof board, and are tightly fixed with steel nails at the splicing point, so between the outer corner fireproof board and the adjacent outer corner fireproof board, between the outer corner fireproof board and the inner corner fireproof board, and the inner corner fireproof board and the adjacent fireproof board. The inner corner fireproof boards can be seamlessly connected, and the internal special-shaped columns can be reliably fireproof and insulated through the outer-to-inner fireproof boards, thermal insulation fibers and fireproof coatings, thus protecting the special-shaped columns and their entire frame structure.

After the above structure is adopted, the beneficial effects of the present invention are: the fireproof structure for special-shaped columns described in the present The special-shaped column of the inner corner structure has the advantages of simple structure, reasonable setting, low production cost and the like.
