井梁とを収納して耐火被覆している。Conventionally, as a structure in which a frame of a building unit is fireproof coated, a fireproof structure of a unit house described in Japanese Patent Laid-Open No. 64-39447 is known. In the fireproof structure of the publication, a soft fireproof filler is interposed between an upper-floor building unit and a lower-floor building unit, whereby a covering material attached to a floor beam of the upper-floor building unit and a lower floor are installed. The lower part of the covering material attached to the ceiling beam of the building unit of is continuous. The upper part and the lower part of these covering materials form a fireproof space for housing the floor beam and the ceiling beam, and the floor beam and the ceiling beam are housed in this fireproof space for fireproof coating.

Regarding 0B, the tip portions 32C of the fire-resistant covering material 32 contact each other only by arranging the lower-floor building unit 10B adjacently,
Thus, the lower portion 37 of the refractory space in which the adjacent ceiling beams 14 are collectively arranged is configured. Therefore, the work for forming the lower refractory space 37 at the construction site is unnecessary and the work amount is reduced. Then, the ceiling material 42 is installed between the adjacent lower floor building units 10B, and the ceiling materials 36 of the adjacent lower floor building units 10B are connected.

In the second embodiment described above, the soft fireproof coating material 50 is attached to the upper end of the fireproof coating material 46 to form the fireproof space lower portion 45, but as shown in FIG. The refractory coating 54 is provided with a receiving portion 54A, and the soft refractory coating 56 that abuts the lower surface of the ALC plate 22 is fixed to the receiving portion 54A to form a lower refractory space 58.

Since the soft refractory coating material is brought into contact with the ALC plate having a large area, the closed refractory space in which the upper part of the refractory space and the lower part of the refractory space are surely continuous can be formed. This ensures a predetermined fire resistance performance even when there is a large error in assembly between the lower-floor building unit and the upper-floor building unit.
