PROBLEM TO BE SOLVED: To provide a fire-resistive covering structure which can reduce a covering range, and facilitates the inspection work thereof. SOLUTION: The fire-resistive covering structure 4 is mainly formed of four fire-resistive boards 5 enclosing the periphery of a sliding bearing 2 fixed to the lower end of a square column H, and fire-resistive blankets 6 covering a sliding plate 3 fixed to an upper bed of a foundation footing F arranged adjacently to a lower portion of the square column H. The internal side edge 6a of each fire-resistive blanket 6 is fitted into a gap between the lower edge 5a of the fire-resistive board 5, and the sliding plate 3 to block the gap.
