A fireproof structure having projections is provided to surround an outer surface of a structure, to expand by a high temperature heat in case of fire to protect the structure, and to prevent deterioration of performance of the heat-sensitive structure by easily ensuring ventilation. According to the present invention, the fireproof structure having projections comprises: a fireproof cover of a tubular or plate shape made of a thermally expandable resin to expand by the heat in case of fire, and installed to surround the outer surface of the structure; a plurality of expansion ribs formed to be projected on the outer surface of the fireproof cover; and a plurality of spacing projections formed to be projected on an inner surface of the fireproof cover to come in contact with a surface of the structure, to separate the fireproof cover from the outer surface of the structure. |
