ことを特徴としている。Summary of the invention (1) The method for constructing a cable penetration part of the present invention is to place one support fitting or 2i11 of (3) from above the floor at the floor penetration opening where the cable is routed through, and position the cable in the separated part. Then, the upper side end part is hooked to the E part of the floor. Next, the inorganic fiberboard is placed on the lower side end part of the support metal At so that the cables pass through it four times, and then the fireproof filler is inserted. It is characterized in that it is filled so as to cover the gap between the cable and the through hole.
くべ） 実施例 以下本発明を、１３ＩＩ面を参照しながら説明する。Kube) Example The present invention will be described below with reference to the 13II plane.

上辺を床上部に掛止めされる。FIG. 1 is a longitudinal sectional view showing a cable penetration part of a floor according to the present invention. This floor cable penetration section is constructed as follows. That is, the cable l is inserted into the cable penetration hole formed in the floor 5, the cable is inserted into the open part on one side of the steel wire support fitting 3 at the upper part of the floor, and the steel wire support fitting 3 is passed through α. It is inserted into the opening 6, and the upper side of the steel wire support fitting 3 is latched to the upper part of the floor.

密に充填する。It is formed by making a cut in the center and on one side from the center. Therefore, the refractory filling 02 was added to the area around Ke-Puru 1! ! #Densely fill the gap between the fiberboard 3 and the α-hole 6 into the octogen.
以上により１本発明の方法に係わるケーブル４通部が完
成する。Through the above steps, four cable sections according to the method of the present invention are completed.
