To provide a chain locker for a vessel, etc., with no need for secondary processing of lining wood.SOLUTION: A round type chain locker 1 is provided with wood lining 12 on an inner surface of cylindrical shape side wall made of a steel plate, a plurality of lining wood materials 13 constituting the wood lining 12 have square cross-sectional shapes, and each lining wood material 13 is attached to the inner surface of side walls 11 with spacing between each other. The lining wood material 13 has a plurality of bolt insertion holes 21 bored with spacing in between in the vertical direction, and the bolt insertion holes 21 are each composed of a shaft hole 22 for having the bolt go through and a nut storage unit 23 formed coaxially on the outer surface of the shaft hole. Gaps are smaller than the diameter of an anchor chain 3 to be stored. There is no need for secondary processing to form a trapezoidal cross section by chamfer processing cutting end surfaces of the lining wood materials 13 since a gap exists between the lining wood materials 13. Therefore, lining construction to the chain locker 1 is capable of being carried out with a small number of man hours.SELECTED DRAWING: Figure 1
【課題】内張り木材の二次加工の必要がない船舶等の錨鎖庫を提供する。【解決手段】丸型の錨鎖庫1において、鋼板製の円筒形側壁の内面に木製内張り12が設けられており、木製内張り12を構成する複数本の内張り木材13はその断面形状が四角形であって、各内張り木材13が互いに隙間をあけて側壁11の内面に取付けられている。内張り木材13は、縦方向において間隔をあけて複数個のボルト挿通孔21が穿孔され、ボルト挿通孔21は、ボルトを通す軸用孔22とその外面部に同芯に形成されたナット収納部23からなる。隙間は、格納するアンカーチェーン3の径よりも小さい。内張り木材13同士の間に隙間があることから、内張り木材13の端面を切除する面取り加工して台形断面とする二次加工が必要なくなる。そのため、少ない工数で錨鎖庫1への内張り施工が行える。【選択図】図1
