されている。It is well known that the structures and materials used in passenger ships, cargo ships, fishing boats, etc. are subject to strict regulations both internationally and domestically for the safety of human life at sea. For example, edging materials called coamings (sometimes called collars) are originally installed around openings in ship bulkheads, decks, hatches, roofs, etc. to prevent water and seawater from flowing in. When passing electrical wires (including various cables and tubes such as conduits) through such openings and filling them with filler to secure them, the Intergovernmental Maritime Consultative Organization (IMC0) ), International Maritime Organization (abbreviated as IMO),
Safety of Life at Sea (abbreviated as SOLAS)
In addition to international conventions and standards for electrical wires, the electrical wires have heat resistance values that satisfy and are approved by the competent authority in terms of not only water pressure resistance but also fire resistance, etc. It is said that it must be.

次第に硬化させるような組成物が広く利用されている。Generally, in order to improve the water pressure resistance and fire resistance of the electrical wire penetration part, it is sufficient to lengthen the combing and thicken the filler layer. The more curves there are, the more difficult it becomes to bend suddenly, and the space inside the ship is also curved! Since the electric wires used in 7 are occupied by J: and cannot be used effectively, it is possible to shorten the 1-mining and thin the filler layer, and reduce the number of electric wires and wires to be passed through 7 as much as possible. There is a demand for making the combing easier to bend.Therefore, although many measures have been taken to address this demand, currently the length of the combing is at least 200mm.
For the filler and j-7, for example, various clay silicates, refractory metal oxides such as alumina and magnesia, pozzolanic inorganic compounds such as gypsum, glass fiber 1,
Composition consisting of powdered inorganic materials such as fire-resistant inorganic fibers such as asbestos and rock wool, and water or an inorganic binder such as sodium silicate, which are mixed appropriately to form a pub and gradually harden after filling. things are widely used.

When opening [between the coaming (edge material) surrounding one part and the electric wires, or between the electric wires and the electric wires, at least = between the coaming and the electric wires at a distance close to the ceramic We adopted the method of inserting a spacer and installed it, and we will describe the fraud of 6F.

Not only bulkheads but also roofs1. It can be applied to almost all parts of ships, including hatches and other parts commonly called partition plates, as well as ceilings, bulkheads, etc. of fireproof buildings. Further, the electric wires of the present invention are not limited to those for electric power or communication, but include all ordinary cables with insulation coatings and tubes such as electric conduits.

なるからである。In addition, the ceramic spacer used in this invention (herein) may be made of clay or other silicate minerals, powders of refractory oxides such as alumina, silica, magnesia, zirconia, calcia, etc. themselves or with water or other binder. Although there are no particular limitations, it is not desirable to have fire resistance that cracks or softens at temperatures lower than 1000°C.Also, regarding the shape, dimensions, etc. of the molded product, is a parallelepiped, preferably a rectangular parallelepiped, from the viewpoint of inserting it between the coaming and the electric wires or between the electric wires and maintaining the respective spacing stably. At least one of the surfaces is a concave surface that is close to the curvature of the outer surface of the wire, and the distance between the wires is determined by the thickness of the thinnest part of the concave surface. For example, it is convenient if it is set to 81N1m, and in normal cases, the length is 15 to 25 mtn, the width is 10 to 20 rom, and the thickness is 3
~l Q rnnv can be used as a guideline. This is because if the size is smaller than the lower limit above, it will be difficult to handle, and if the size is larger than the upper limit, the amount of filler used will be reduced.
This is because the water pressure resistance and mechanical strength necessary for the opening are maintained, making it difficult to maintain the water pressure resistance and mechanical strength required for the opening.

らず挿入しておくことが望ましい。When inserting such a ceramic spacer between the combing and the electric wires or between the electric wires, it is necessary to Apply the filler from one side of the opening and push in the spacers sequentially from the other side to arrange the spacer. Fill the gap in the opening with filler in advance 1-1 Push the spacers in sequence from one or both sides until they are at the same level as the edge of the combing, and remove any excess filler that protrudes from the inside to form a flush surface. It is desirable to take this into account. Considering heat conduction in the event of a fire, there is a possibility that the coaming made of metal plates such as steel plates will reach the highest temperature, so in order to prevent this heat from propagating to the electric wires, it is necessary to connect the coaming and the electric wires at least a distance I from the coaming to the nearby electric wires. It is desirable to insert it in between.

Five types of cables a, b, c, d, and e (the length of each cable is 375 mm) based on 3410 were penetrated in the arrangement shown in the figure. The remaining space is filled with a filler (manufactured by Nitto Kasei Kogyo Co., Ltd.) whose active ingredient is a powder consisting of about 50% glass fiber, about 40% inorganic binder, and about 10% inorganic swelling agent (all by weight).

The opposing surfaces of m are all concave curved surfaces, and the thickness of the thinnest part is 8 mm) As shown in the figure, connect combing 1 and the cables close to it (a7, blO, c1, 61, e1). Push the concave curved surface of the spacer 3 along the outer surface of the cable between the cables (20 pieces in total), and remove the excess filler that has been extruded with the end surface of the spacer 3 aligned with the edge of the coaming 1. , Filler 2 was cured.

(February 29, 2016), the standard fire test for the A-class electrical wire penetrations on ships was entrusted to the Japan Ship Quality Control Association Ship Maintenance Components Research Institute. The main test conditions and conditions at this time are as follows. That is, the atmospheric temperature in the test room was 29℃, the relative humidity was 78%, the test furnace was of the standard type in the above laboratory, and the standard temperature increase rate was 556℃ after 5 minutes, 1
659'C after 0 minutes, 718'C after 15 minutes, 82 after 300 minutes
After 1.600 minutes, the temperature was adjusted to 925, and the test specimen was fixed to the test bulkhead with bolts. The heat source was city gas, and the pressure inside the furnace at the test specimen position was 10 ± 1 Pascal. Ta.

No gaps were observed in the contact areas between filler 2 and each cable 1 to e or combing 1, and no cracks were observed on the non-heated surface. Falling off of the spacer 3 on the surface side and damage to the coaming 1 and partition walls were not observed.

There was no air leak. Furthermore, since the spacer 3 is made of porcelain with high hardness, it has the secondary effect of not being damaged by mice at all.

It can be made as low as this. Therefore, it can be concluded that the method of constructing the electrical wire penetration part of the present invention greatly contributes not only to safety inside a ship but also to the effective use of narrow spaces in structures other than ships.
