次に、本実施例１に係る自動車運搬船のカーゴホールド用通風ダクト配置における前記間隙ｄ１〜ｄ１３についての構造について説明する。
本実施例１に係る自動車運搬船のカーゴホールド用通風ダクト配置においては、前記上層デッキ消火区画Ｃ−ＺＯＮＥ内で隣接配置される前記下層デッキ用各通風ダクトと前記上層デッキ用各通風ダクトのダクト間の間隙ｄ１〜ｄ１３について、前記上甲板３までの長さの短い前記上層デッキ用通風ダクトｃ４、ｃ７、ｃ８、ｃ９、ｃ１０、ｃ１１、ｃ１３、ｃ１４、ｃ１７、ｃ３１、ｃ３６、ｃ４０、ｃ４１について、前記下層デッキ用通風ダクトａ１、ａ３、ｂ１、ｂ２、ｂ３、ｂ４、ｂ５、ｂ７、ｂ９、ａ４、ｂ１０、ｂ１３側の幅（深さ）を短くして、前記間隙ｄ１〜ｄ１３を形成して両者の隣接を回避するようにする。すなわち、間隙ｄ１〜ｄ１３を形成する際には、前記上層デッキ用通風ダクトｃ４、ｃ７、ｃ８、ｃ９、ｃ１０、ｃ１１、ｃ１３、ｃ１４、ｃ１７、ｃ３１、ｃ３６、ｃ４０、ｃ４１について、近接する側（前記下層デッキ用通風ダクトに近い側）の幅（深さ）を短くサイズ調整をして、両者の間に前記間隙ｄ１〜ｄ１３を設けて配置する。 Next, the structure of the gaps d1 to d13 in the cargo hold ventilation duct arrangement of the car carrier according to the first embodiment will be described.
In the cargo hold ventilation duct arrangement of the car carrier according to the first embodiment, between the ventilation ducts for the lower deck and the ventilation ducts for the upper deck arranged adjacent to each other in the upper deck fire extinguishing section C-ZONE. The upper deck ventilation ducts c4, c7, c8, c9, c10, c11, c13, c14, c17, c31, c36, c40, c41, which are short to the upper deck 3, The gaps d1 to d13 are formed by reducing the width (depth) of the lower deck ventilation ducts a1, a3, b1, b2, b3, b4, b5, b7, b9, a4, b10, b13. Avoid adjoining the two. That is, when the gaps d1 to d13 are formed, the upper deck ventilation ducts c4, c7, c8, c9, c10, c11, c13, c14, c17, c31, c36, c40, c41 are adjacent to each other ( The width (depth) of the lower deck ventilation duct is adjusted to a short size (depth), and the gaps d1 to d13 are provided between them.

次に、本実施例１に係る自動車運搬船のカーゴホールド用通風ダクト配置に係るこれらの間隙ｄ１〜ｄ１３間を含む前記上層デッキ用通風ダクトｃ４、ｃ７、ｃ８、ｃ９、ｃ１０、ｃ１１、ｃ１３、ｃ１４、ｃ１７、ｃ３１、ｃ３６、ｃ４０、ｃ４１及び、前記下層デッキ用通風ダクトａ１、ａ３、ｂ１、ｂ２、ｂ３、ｂ４、ｂ５、ｂ７、ｂ９、ａ４、ｂ１０、ｂ１３の両ダクトの外面に対して防熱施工を行う。   Next, the upper deck ventilation ducts c4, c7, c8, c9, c10, c11, c13, c14 including the gaps d1 to d13 related to the arrangement of the cargo holding ventilation ducts of the car carrier according to the first embodiment. , C17, c31, c36, c40, c41 and the lower deck ventilation ducts a1, a3, b1, b2, b3, b4, b5, b7, b9, a4, b10, b13 Perform construction.

この結果、ＲｏＲｏ区画が隣接する場合には隣接壁面に防熱施工が要求され、通風ダクト同士が隣接する場合にも、その通風ダクト同士の内面に防熱施工をしなければならないこととなるが、本実施例１に係る自動車運搬船のカーゴホールド用通風ダクト配置においては、ＲｏＲｏ区画が隣接する場合にも、それらの区画に通風する通風ダクト間に前記間隙ｄ１〜ｄ１３を設けたので、両通風ダクトの外面のみに防熱施工をするだけで足り、防熱施工、特に、ダクト内面への狭隘箇所への難易度の高い防熱施工作業を回避することができるので、作業効率を格段に向上することができる。   As a result, when the RoRo section is adjacent, heat insulation work is required on the adjacent wall surface, and even when the ventilation ducts are adjacent to each other, the heat insulation work must be performed on the inner surfaces of the ventilation ducts. In the cargo hold ventilation duct arrangement of the car carrier according to the first embodiment, even when the RoRo section is adjacent, the gaps d1 to d13 are provided between the ventilation ducts that ventilate the sections. It is sufficient to perform heat insulation work only on the outer surface, and it is possible to avoid heat insulation work, in particular, a highly difficult heat insulation work operation to a narrow part on the inner surface of the duct, so that work efficiency can be significantly improved.

また、ダクト内面への防熱施工を回避することができるので、ダクトを通じた防熱材料の飛散等を避けることができ、カーゴダメージを避けることができる。
そして、ＲｏＲｏ船のＲｏＲｏ区画の隣接が回避できるので、船舶火災上も安全性向上に寄与することができることとなる。 In addition, since heat insulation work on the inner surface of the duct can be avoided, scattering of the heat insulation material through the duct can be avoided, and cargo damage can be avoided.
And since the adjoining of RoRo section of a RoRo ship can be avoided, it can contribute to safety improvement also on ship fire.

本発明は、ＲｏＲｏ船(ROLL ON ROLL OFF船)である自動車運搬船のカーゴホールド用通風ダクト配置に利用される。   The present invention is used for the arrangement of air ducts for holding cargo in an automobile carrier ship that is a RoRo ship (ROLL ON ROLL OFF ship).
