To provide an easy-to-construct structure for taking fire-resisting measures for a through-hole, which requires only a small used amount of thermally-expansible gap filling material.
A long body supporting rack 1, which includes right and left side plate portions 4 and a bottom plate portion 5a and the upper portion of which is structurally formed as an opening or opened, is inserted into the through-hole H, formed in a partition body W, in the state of receiving and supporting a long body K by the bottom plate portion 5a. A cover member 3 for the fire-resisting measures, which closes a gap between the long body supporting rack 1 and the through-hole H, is provided in the opening of the through-hole H in a state in which the thermally-expansible gap filling material 2 for the fire-resisting measures, arranged on the upper portion of the long body K, is sandwiched between the long body K and the cover member.
