が出来ないものであつた。 In general, in the cable penetration part where the cable passes through the cable penetration hole provided in the wall, floor, etc., non-hardening or non-drying fire prevention putty is applied near the penetration opening at both ends of the cable penetration hole in order to impart fire protection. The through hole is sealed by filling the through hole. However, in such a structure, if the cable penetration part becomes hot due to the heat generated by the cable or if a fire occurs, the putty may lose its shape or soften, making it unable to exhibit sufficient fire protection performance.

In other words, the present invention involves passing a cable through a cable penetration hole provided in a wall, floor, etc., installing a fireproof plate in the penetration hole at both ends, and filling the outside with non-hardening or non-drying type fire prevention putty to seal it. Furthermore, a hardening type or drying type fire prevention putty is coated on the outside.
本考案の１例を図面にもとづき詳細に説明す
る。 An example of the present invention will be explained in detail based on the drawings.

貫通部の防火構造とするものである。 The cable 1 is passed through a cable through hole 3 provided in the fire wall 2, and the inside of the through hole is filled with a heat insulating material 4, for example, an inorganic heat insulating fiber such as rock wool. , 5', and apply non-curing or non-drying putty 6, on the outside.
6'For example, a non-hardening organic oil or liquid aggregate is used as a binder, and a mixture of flame retardant material, inorganic filler, and reinforcing fibers is pressed into the binder, and hardening or dry putty is applied on the outside. 7, 7' For example, the cable penetration part of the present invention can be made fireproof by coating a mixture of a room-temperature curing resin, a drying oil such as boiling oil, etc. as a binder and adding a flame retardant, an inorganic filler, and reinforcing fibers to the binder. It is a structure.

パテを薄く被着することが好ましい。 In this way, the present invention uses two types of putty, non-hardening putty and hardening putty, and the former is provided as an inner fireproof layer and the latter is provided as a double layer like an outer fireproof layer, and the layer thickness is limited. Although not necessarily, it is preferable to use non-curing putty as the main material and to apply a thin layer of curable putty on the outside.

る。 As described in detail above, according to the present invention, even if the cable reaches high temperatures, since the outer fireproof layer is provided with hardening putty, the cable does not soften or lose its shape, and exhibits sufficient fireproofing properties. In addition, since the inner fireproof layer is provided with non-hardening putty, if the cable is subjected to vibrations, it will easily follow the vibrations, and the fireproof structure will not be affected. Moreover, it has remarkable effects such as making it easier to remove or replace cables.
