[0012]
FIG. 1 is a configuration example of a container support structure for a container ship according to the present invention. FIG. 1 is a sectional view of an intermediate support portion located in the middle of a lashing bridge, and FIG. 2 is a side view thereof. In the figure, 11 is an upper deck, 12 is a hatch formed on the upper deck 11, 13 is hatch combing that borders the hatch 12, and 14 is a ship side skin.
[0013]
The illustrated container support structure is configured such that a support beam 20 as a container support member is provided at the upper end of a hatch combing 13 erected on the upper deck 11 with the opening edge of the hatch 12 being bordered. The hatch combing 13 and the ship side outer plate 14 have a predetermined interval, and this is a deck passage 15.
[0014]
The hatch combing 13 is formed of a steel plate, and a horizontal plate 13B is fixed to an upper edge of a vertical plate 13A erected on the upper deck 11 along an opening edge of the hatch 12, and an inner edge of the horizontal plate 13B is a hatch 12. The outer edge protrudes to a position substantially matching the ship side skin 14. A support beam 20 is integrally formed on the upper surface on the ship side of the vertical plate 13A of the horizontal plate 13B of the hatch combing 13, and the hatch cover 30 is placed on the upper surface of the horizontal plate 13B on the ship center side. It is like that.
[0015]
The support beam 20 is formed of a steel plate having a thickness matching the upper surface of the hatch cover 30 placed on the horizontal plate 13B, and the inner side (ship center side) surface and the horizontal plate 13B are triangular. The ribs 21 are firmly connected. Further, an auxiliary support column 22 is disposed between the outer edge corner portion of the lower surface of the horizontal plate 13 </ b> B and the upper deck 11. That is, the support beam 20 extends from the hatch coaming 13 to the ship side and is supported in a cantilever state mainly by the hatch coaming 13, and is configured to support the auxiliary support pillar 22 as an auxiliary. The combing 13 and the auxiliary support pillar 22 are set so that the weight of the container 40 loaded on the support beam 20 can be supported. If the strength is acceptable, the auxiliary support pillar 22 may be omitted.
[0016]
Container sockets 23, 31 are provided at predetermined positions on the upper surface of the corner on the ship side of the support beam 20 and the upper surface of the hatch cover 30. The container sockets 23, 31 are engaged with the container sockets 23, 31 above the deck passage 15. Container 40 is loaded. That is, both ends in the width direction of the container 40 are supported by the support beam 20 or the hatch cover 30, respectively.
[0017]
In the figure, reference numeral 18 denotes a vertical ladder disposed on the vertical plate 13A of the hatch coaming 13, and occupants and loaders are connected to the support beam 20 from the deck passage 15 via an access hatch 24 provided on the support beam 20. It is for moving to the upper side. Reference numeral 19 denotes a handrail.
[0018]
In the container support structure as described above, the support beam 20 on which the weight of the loaded container 40 acts is supported mainly in a cantilever state by the hatch combing 13 and the side ends thereof are supplementarily supported by the auxiliary support columns 22. The cross section of the auxiliary support column 22 can be reduced, and the auxiliary passage 22 can be set so as not to occupy the deck passage 15 and to narrow the deck passage 15.
[0019]
Next, the container support structure in the lashing bridge part which shows sectional drawing in FIG. 3 and A arrow view corresponding to the side view in FIG. 4 is demonstrated. Parts having the same functions as those in the above configuration example are given the same reference numerals and description thereof is omitted.
[0020]
In the illustrated lashing bridge portion, a lashing bridge 50 continuous in the width direction of the ship is supported and provided by a plurality of lashing bridge columns 51 erected on the upper deck 11 at a predetermined interval. The two lashing bridge columns 51 </ b> A and 51 </ b> B located on the ship side are erected on the support beam 20 formed on the horizontal plate 13 </ b> B of the hatch combing 13.
[0021]
Further, the diagonal member 25 is located between the intersection of the lashing bridge column 51A and the lashing bridge 50 located closest to the ship side, and the vicinity of the base of the lashing bridge column 51B located second from the ship side (intersection with the support beam 20). Is arranged.
[0022]
In this configuration, the weight of the container 40 that acts on the support beam 20 acts on the hatch combing 13 via the lashing bridge 50 and the diagonal member 25, so that the auxiliary column 22 in the above configuration example can be omitted. Accordingly, the deck passage 15 is not occupied by the strength member that supports the container 40, and a wider passage width can be secured.
[0023]
【The invention's effect】
As described above, according to the container support structure of the container ship according to the present invention, the container support member that protrudes laterally and is positioned on the passage is provided at the upper end of the hatch combing , Constructed integrally with the lashing bridge, there is no support for supporting it near the ship side skin, and the container is loaded on the upper surface of the container support member so that the hatch combing receives the weight. In order to support the container support member on which the weight of the loaded container acts in a cantilever state by hatch combing, the member receiving the container weight does not occupy the deck passage and narrows the deck passage, A wide passage width can be secured.
[0024]
In addition, since the container support member is configured integrally with the lashing bridge, it can be configured with high strength, and the container weight can be more efficiently transmitted to the hatch combing. A wide passage width can be ensured by the absence of supporting columns.
