３，３′の通し孔に縦貫通させた。 In FIG. 1, when the cable 1 vertically passes through the through hole 2a bored in the floor 2, the through hole 2a
Thermal insulation material 3 packed into the space around the cable 1 inside
is manufactured in advance as follows. That is, a rock board (a rock board whose surface has been coated with a fire spread preventive agent and dried may also be used) having a thickness half that of the floor is prepared, cut to a size larger than the diameter of the floor through hole 2a, and the cable 1 is inserted in the center. Drill a cable passage hole that is slightly smaller than the outside diameter of. and,
Rock board insulation material 3 produced in this way
were packed and arranged on the lower side of the floor through hole 2a. Furthermore, using a lock board cut to the same thickness and outer dimensions as above, a cable passage hole larger than the outer diameter of the cable (approximately 30 to 50 mm) was bored in the center. Then, the rock board heat insulating material 3' produced in this way was packed and arranged so as to rest on the upper surface of the lower heat insulating material 3 at the upper side of the floor through hole 2a. Then, the cable 1 was vertically passed through the through holes of the heat insulating materials 3 and 3'.

As a result, an annular groove is formed with the bottom of the lower heat insulating material 3 that is in close contact with the cable and surrounded by the through hole of the upper heat insulating material 3' and the cable surface. Pour a liquid flame-retardant compound into this groove, make sure that the flame-retardant (liquid) compound is sufficiently familiar with the cable surface and the insulation materials 3, 3', and let the flame-retardant compound harden. A cured layer 5 of flame retardant compound is then formed.

The minimum inner diameter on the lower side is slightly smaller than the outer diameter of the cable, and the maximum inner diameter on the upper side is larger. The rock board insulation material 3 produced in this way is inserted into the floor through hole 2.
Then, the cable 1 was passed vertically through the central through hole.

The lowest internal diameter portion of the bottom that comes into close contact with the cable serves as the bottom, and forms an annular groove surrounded by the slotted cut and the cable surface. A liquid flame retardant compound is injected into this groove in the same manner as in the embodiment described above to form a hardened layer 5 of the flame retardant compound, and then a flame retardant putty is applied from the surface side over the cable and the heat insulating material. It has 6 banks. In this embodiment as well, a bank of flame-retardant putty is applied to the lower cable penetration portion.

According to the disaster prevention seal construction method for the cable floor penetration part of the present invention as described above, the cable passage hole of the insulation material itself, which is stuffed into the floor penetration hole for the cable to pass through, is devised so that the lower side is closer to the outer diameter of the cable. The outer diameter of the cable is made smaller and larger than the outer diameter of the cable on the upper side, so that the small diameter hole on the lower side is in close contact with the surface of the cable, and the large diameter hole on the upper side is separated from the surface of the cable. An annular groove surrounded by the cable surface and the large diameter hole of the insulation material itself is formed as the bottom of the lower cable contact part,
Since this groove is filled with liquid flame retardant compound to form a predetermined hardened layer, there is no need for any special container for injecting and curing the liquid flame retardant compound, and the amount of compound can be reduced to form a predetermined hardened layer. A cured layer of flame retardant compound can be formed.
また、液状難燃性コンパウンドが、断熱材が接
触すべきケーブルの表面と断熱材の切り口に直接
注入されて所定の硬化層となるため、ケーブル表
面及び断熱材との密着性が向上する。 Furthermore, since the liquid flame-retardant compound is directly injected into the cut end of the insulation material and the surface of the cable where the insulation material should come into contact, forming a predetermined hardened layer, the adhesion between the cable surface and the insulation material is improved.
さらに、難燃性コンパウンドの硬化層がケーブ
ルの表面に対して断熱材が接触する厚さ分におい
て密着するため、ケーブル表面に対する密着部分
の長さを従来（第４図のもの）より大きくでき
る。 Furthermore, since the cured layer of the flame retardant compound adheres to the surface of the cable by the thickness of the heat insulating material, the length of the part that is in close contact with the cable surface can be made larger than that of the conventional cable (as shown in FIG. 4).
以上のことから、次のような効果が導き出され
る。 From the above, the following effects can be derived.
(1) 難燃性（液状）コンパウンドの使用量が少な
くて済み、経済的である。(1) It is economical because the amount of flame retardant (liquid) compound used is small.
(2) 難燃性コンパウンドの硬化層の高さ（厚さ）
は通常25mm程度であるが、本発明の場合、少な
くとも断熱材となるロツクボードの厚み（50
mm）が難燃性コンパウンドのケーブルとの接触
長になるので気密性を保つ層が厚くなるため、
気密性が向上し火災時の煙の通過が防止でき
た。(2) Height (thickness) of the cured layer of flame retardant compound
is usually about 25 mm, but in the case of the present invention, at least the thickness of the rock board (50 mm)
mm) is the contact length of the flame-retardant compound with the cable, so the layer that maintains airtightness becomes thicker.
Improved airtightness and prevented smoke from passing through in the event of a fire.
(3) 断熱材のケーブル通し孔を加工して液状難燃
性コンパウンドの充填溝を作るので、液状難燃
性コンパウンドの注入作業が容易となり、作業
能率が向上した。(3) Since the cable passage hole in the insulation material is processed to create a groove for filling the liquid flame-retardant compound, it is easier to inject the liquid flame-retardant compound, improving work efficiency.
(4) 難燃性コンパウンド及び難燃性パテの使用部
分が少ないので、増設・撤去に容易に対応する
ことができる。(4) Since there are only a few areas where flame retardant compound and flame retardant putty are used, it can be easily expanded or removed.
(5) 床貫通孔内でケーブルの周囲に難燃性コンパ
ウンドの硬化層を形成しても、貫通孔内に詰め
込む断熱材が当該硬化層の周囲にも存在させる
ことができるため、ケーブルの長手方向及び径
方向における断熱効果が大きい。(5) Even if a hardened layer of flame-retardant compound is formed around the cable in the floor through-hole, the heat insulating material packed into the through-hole can also be present around the hardened layer. Great heat insulation effect in direction and radial direction.
