るというものである。[Prior Art] When a fire occurs in a building, the fire often spreads through four cable holes in the floor or wall of the building. For this reason, the conventional construction method was to completely seal the cable penetration hole in the building with fire-resistant material.
As for the specific processing method, as shown in Fig. 3 which shows the structure of the member according to the construction method, one side of the cable 4 passage hole 11 in the floor or wall 1 of the building is made to match the shape of the through hole. The cut fireproof plate 61 is attached to the fixed poles 1 to 7, and then the gap between the cable 2 to be laid and the fireproof plate 6 is filled with heat-resistant caulking material 4, and the through holes 11 are filled with heat-resistant caulking material 4.
A predetermined amount of non-combustible M21F 5 is packed inside, a fireproof plate 62 is attached to the side where it will be used, the gap between the fireproof plate 6 and the cable 2 is filled with heat-resistant caulking material 4 and sealed, and both sides are sealed. There was a method of applying a fire spread preventive agent 8 to a predetermined thickness around the area. By sealing the cable through hole 11 using this method, in the event of a fire in the building, the fire is prevented from spreading through the cable through hole 11 to the remote location.

いう幾多の問題があった。[Problems to be Solved by the Invention] In the above-mentioned conventional method for forming cable through holes 11, skill is required to process the fireproof plate 6, and dust is generated during the process, resulting in sanitary problems in the working environment. For health reasons, there are restrictions on where the processing work can be done, and the processing of the fireproof board 6 itself is inefficient, and since the fire spread prevention agent 8 is water-based, it takes several times to form a coating film of a predetermined thickness. It is necessary to apply the above layers in multiple layers, and it requires a long period of drying time after each application.Also, when applying, the paint scatters and stains the surrounding area and the floors and walls of the building, so it is necessary to Curing is required, which is extra time, and the fire spread prevention agent 8 forms a strong coating film after drying, which causes the coating to peel off and move, making it impossible to easily add or remove cables.
Furthermore, since it is necessary to proceed with the construction work from both sides, there are many problems in that in the case of joint construction, the work cannot be carried out continuously and is inefficient.

A novel method for sealing a cable through hole is provided. That is, the present invention is a method for sealing a cable through-hole, which is characterized by sealing the cable through-hole with a noncombustible inorganic fiber board and a heat-resistant caulking material.

is provided, and the cable 2 is laid through the through hole 11. When carrying out the sealing treatment method of the present invention for these four through holes 11, the support fittings 3 are first placed in the through holes 11. Several supporting metal fittings 3 are used as appropriate depending on the size and shape of the through hole 11. On the other hand, a heat-resistant caulking material 4 formed into a sheet having a thickness of approximately 5 to 1 Qmm is tightly wrapped around the portion of the cable 2 located in the through hole 11. Next, as shown in FIG. 2, an inorganic noncombustible fiberboard 5 with a thickness of 50 mm or more, which has been cut according to the shape of the through hole 11 and the cable installation situation, is inserted into the through hole 11, and the cable 2 and The gaps between the inorganic non-combustible fiberboards 5 and the gaps between the cables 2 are filled with a heat-resistant caulking material 4. By performing such treatment, the two sides of the floor 1 are isolated by heat-resistant material, and mutual air circulation is blocked, so that even in the event of a fire in the building, the fire will not spread through the cable penetration holes 11. .
