Furthermore, the outer surface of the exterior member 11b of the thermally expandable refractory material 11 is in pressure contact with each wiring / piping material group 101,102.

  Further, in the long side direction and the short side direction of the through hole Wa, between the thermally expandable refractory materials 11, between the peripheral surface Wb of the fire prevention compartment floor W and each wiring / piping material group 101, 102, When a gap smaller than the size of the thermally expandable refractory material 11 is formed between the wiring / pipe material 100 and the like, the thermally expandable refractory material 11 is filled in accordance with the size of the gap. That is, the thermally expandable refractory material 11 is cut into a required size and used. Further, in a slight gap formed between each wiring / piping material group 101, 102 and the thermally expandable refractory material 11 and between the gantry 13 and the wiring / piping material 100, a heat-expandable heat-resistant sealing material (see FIG. (Not shown) is filled.

  Now, in a building in which the through-hole structure T is formed on the fire prevention compartment floor W, it is assumed that a fire or the like has occurred on the lower side of the fire prevention compartment floor W, and both the wiring / piping material groups 101 and 102 have burned. At this time, it is the exterior member 11 b of the thermally expandable refractory material 11 that is in pressure contact with the outer surface of the wiring / piping material group 101, 102. And the exterior member 11b consists of a flame-retardant heat-expandable heat-resistant material. For this reason, the exterior member 11b is not immediately burned away by the heat generated from the thermally expandable refractory material 11, and the exterior member 11b expands upon receiving heat. Moreover, since the block body 11a is formed from the material which has nonflammability, when the exterior member 11b expand | swells, the block body 11a does not burn.

  Then, the heated exterior member 11b expands toward the thermally expandable refractory material 11, and the exterior members 11b that are in pressure contact with each other join (weld) to form a plurality of thermally expandable refractory materials 11 in one lump. The heat-expandable refractory material 11 having a lump shape hermetically seals between the wiring / piping material groups 101 and 102 and the peripheral surface Wb of the fire prevention compartment floor W. That is, the space S becomes a path of flame, smoke, toxic gas, and heat, and flame, smoke, toxic gas, and heat are prevented from being transmitted to the upper side of the fire prevention compartment floor W, and a fire resistance function is exhibited.

According to the above embodiment, the following effects can be obtained.
(1) The refractory material support 20 includes a refractory material receiving plate 30 supported by the support plate 26 of the support main body 21. The refractory material receiving plate 30 is made of non-combustible paper and can be easily cut with a manual cutting tool. The refractory material receiving plate 30 is supported by the support plate 26 so as to extend from the support plate 26 toward the wiring / piping material groups 101 and 102. And the extension length from the support plate 26 of the refractory material receiving plate 30 can be easily adjusted by cutting the extension site | part of the refractory material receiving plate 30 from the support plate 26 with a manual cutting tool. Furthermore, the refractory material receiving plate 30 can be cut from any position in the long side direction. Therefore, unlike the case where the member supporting the thermally expandable refractory material 11 is made of a metal material, the refractory material receiving plate 30 can be easily adjusted to an arbitrary length.

  (2) The refractory material receiving plate 30 has a small rectangular shape, and a plurality of refractory material receiving plates 30 are supported by the support plate 26. Then, by cutting each refractory material receiving plate 30 individually, the length of the refractory material receiving plate 30 can be adjusted so as not to interfere with each wiring / piping material group 101, 102. Therefore, for example, as compared with the case where one large refractory material receiving plate is cut so as not to interfere with each wiring / piping material group 101, 102, the disposing work of the refractory material receiving plate 30 is easily performed. be able to. In particular, it is very troublesome to cut one large refractory material receiving plate along the outer shape of the wiring / pipe material 100. However, in this embodiment, since the plurality of refractory material receiving plates 30 are individually cut, the cutting amount of one refractory material receiving plate 30 is small, and the refractory material receiving plate 30 can be easily cut. it can.

  (3) Each wiring / piping material group 101, 102 has a plurality of wiring / piping materials 100 arranged in parallel, and the outer surface shape of each wiring / piping material group 101, 102 is made uneven by the plurality of wiring / piping materials 100. It has become. The plurality of refractory material receiving plates 30 are supported by the support plate 26 such that the short sides extend in the parallel direction of the wiring / piping material 100. Then, by individually cutting the plurality of refractory material receiving plates 30 in accordance with the outer surface shape of the wiring / pipe material 100, it is possible to easily cope with the uneven shape of each wiring / pipe material group 101, 102. In particular, the refractory material receiving plate 30 is supported by the support plate 26 so that the short side extends in the parallel direction of the wiring / piping material 100. For this reason, the cutting of each refractory material receiving plate 30 is a cutting in the short side direction of the refractory material receiving plate 30, for example, compared to the case where the refractory material receiving plate 30 is cut in the long side direction. The cutting amount of 30 can be reduced, and the cutting work itself of the refractory material receiving plate 30 can be simplified.

  (4) The refractory material receiving plate 30 is bonded (fixed) to the upper surface of the support plate 26 with an adhesive. For this reason, the refractory material receiving plate 30 can be supported by the support plate 26 in a stable state, and the thermally expandable refractory material 11 can be supported by the refractory material receiving plate 30 in a stable state.

  (5) The support body 21 is formed by connecting both ends of the support plate 26 to the connection portion 25 of the pair of support fittings 22. And by changing the length of the support plate 26, it is possible to correspond to the size and shape of the through hole Wa.

  (6) The refractory material receiving plate 30 is made of non-combustible paper whose main component is magnesium silicate. For this reason, the refractory material receiving plate 30 can support the thermally expandable refractory material 11 until the thermally expandable refractory material 11 expands. Moreover, since the refractory material receiving plate 30 is paper, it can be easily cut with a manual cutting tool.

  (7) The refractory material receiving plate 30 is laid all over the long side direction of the through hole Wa by the support plate 26, and the short side direction of the through hole Wa is provided by a plurality of support plates 26 mounted in the short side direction of the through hole Wa. A fireproof material receiving plate 30 is laid throughout. For this reason, the space S is closed by the refractory material receiving plate 30, and the drop of the thermally expandable refractory material 11 from the space S is prevented. Therefore, for example, when the refractory material receiving plate 30 is supported at an interval in the long side direction of the through-hole Wa, the thermally expandable refractory material 11 is prevented from falling. There is no need to consider the position.
