Further, since the width of the refractory filler main body is set to be equal to or larger than the depth-wise filling length required for the refractory treatment, the sheet-like refractory filler main body is wound in the longitudinal direction. In a state where the gap is filled in the gap as described above by turning it into a roll, the required filling length is automatically secured. Therefore, the filling length in the depth direction required for fire resistance can be reliably ensured. In addition, since a sheet-like refractory filler main body wound in a roll shape is filled in the gap, the filling density is made uniform, and the refractory strength is increased.

A small gap is formed between adjacent roll-shaped refractory filler main bodies in a state in which the roll-shaped refractory filler obtained by winding the sheet-shaped refractory filler main body in a roll shape is filled in the gap. In this case, the filling density of the refractory filler in all parts of the gap is substantially reduced by supplementarily filling the small gap with the spare part of the refractory filler remaining after being separated from the main part of the refractory filler. Can be uniform.
