【発明の詳細な説明】
本発明は、ケーブル貫通部防火シール工法の改
良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a fireproof sealing method for a cable penetration part.
従来のケーブル貫通部シール工法では、床や壁
とケーブルとの隙間に耐火性材のシール材を詰め

は、簡単に燃焼してしまう。 In the conventional cable penetration sealing method, a fire-resistant sealant is filled in the gap between the cable and the floor or wall, but in the event of a fire, the cable's sheath made of polyethylene or cross-linked polyethylene can be easily destroyed. It will burn out.
そして、ケーブル周辺に充填されたシール材は
耐火層を作つて延焼をストツプするが、ケーブル

る。 The sealing material filled around the cable creates a fireproof layer to stop the spread of fire, but the part of the cable where the sheath is exposed burns and creates a gap, so there is a concern that flames and smoke may infiltrate through this part. .

とになる。 FIG. 1 shows a cable penetration part formed by a conventional cable penetration part fireproof sealing method, in which a cable 4 is passed through a floor or wall 3 with a heat insulating material 5 interposed, and the floor or wall at the penetration part of the cable 4 is shown. A fireproof plate 2 through which a cable 4 is passed is attached to both sides of the heat insulating material 3 and the heat insulating material 5. As the outside of the fireproof plate 2 is heated, a strong fireproof layer is formed. For example, it is covered with a fireproof sealing material 1 made of liquid polychloroprene mixed with hydrated alumina and organic fibers. Therefore, in the case of a fire, the burnt and damaged portion of the sheath of the cable 4 becomes a cavity as described above, and flames and smoke enter through this cavity.

る。 An object of the present invention is to eliminate the above-mentioned drawbacks and provide a fireproof sealing method for cable penetrations that not only has a strong fireproof layer but also can close gaps caused by burnt cable sheaths and prevent the circulation of flames and smoke. .

のである。 In the present invention, when the cable is heated, the cable sheath maintains almost its original shape until the cable sheath is damaged by combustion, and the sheath is damaged by foaming, expansion, etc. after the cable is heated. A filling and sealing material that has the property of filling parts and containing a chlorine-based binder and bentonite in its formulation is placed, and as it is heated, a fireproof layer is formed so as to cover the filling and sealing material. A fireproof sealing material is placed to hold the fire.

い。 By the way, the filler used for the cable penetration part must not only be a material that does not have concerns about water leakage or peeling off when drying, but also must have sufficient fire resistance and flame retardancy for its original purpose. It won't happen. The above-mentioned formulation of the filling and sealing material took these points into consideration, and as a binder, a chlorine-based substance with extremely excellent flame retardant and water-resistant properties was used. Bentonite is used to absorb toxic gases and smoke. Incidentally, since the filled sealing material formed with the above-mentioned composition is covered with a fireproof sealing member, noxious gas or the like will not leak to the outside from the cable penetrating portion.

トなどを配合したものから形成されている。 Hereinafter, an embodiment of the cable penetration part fireproof sealing method of the present invention will be described with reference to FIG. 2, where the same parts as those in the conventional method are designated by the same reference numerals, and explanations of the same parts will be omitted. A filled sealing material 6 is placed at the part of the fireproof plate 2 where the cable 4 passes through so as to cover the outer periphery of the cable 4, and the filled sealing material 6 remains in almost its original shape until the cable sheath burns and breaks when the cable 4 is heated. After a combustion defect, the sheath fills and closes the defect by foaming, expansion, etc. For example, ammonium polyphosphate, polyhydric alcohol, amino compound, which is a foaming component for a chlorine-based binder such as chlorinated polyethylene, Furthermore, it is formed from a compound containing an expanding component such as bennite.

ける炎や煙の侵入は防止される。 Therefore, in the event of a fire, the cable penetration formed by the fireproof seal construction method of this example maintains its original shape until the cable is heated and the cable sheath burns and breaks, and the sheath does not bubble or expand after the combustion break. Since the defective part of the sheath part is closed and deflected by the filling sealing material 6, the intrusion of flame and smoke at the cable penetration part is prevented.

のである。 As described above, in the cable penetration fireproof sealing method of the present invention, the combustion defective part of the cable sheath is filled and closed by the filling sealing material by foaming and expansion, and this filled and closed part is covered with the fireproof sealing material forming a fireproof layer. As a result, it has excellent fire resistance and water resistance, and also has the effect of preventing the circulation of flame and smoke in the combustion defect part of the sheath, as well as preventing the leakage of harmful gases to the outside of the cable penetration part. be.
