Description
Technical field
The present invention relates to the technical field of coaming, more particularly to a kind of bulk freighter coaming and ship mouthful stringers.
Background technology
Traditional bulk freighter longitudinal direction coaming is generally configured to discontinuous structural shape, can not be counted during proper calculation
Hull beam longitudinal strength.Actual conditions are that coaming has sub-fraction to participate in overall strength, thus for main hull structure
For it is overly conservative compared with actual conditions, and for coaming itself then relatively danger.In addition, traditional is middle-size and small-size
Bulk freighter hatch side girder height is general higher, causes whole top side tank swash plate slightly near apart from natural axis, while also have lost part
Hatch capacity.
The content of the invention
For the problem of above-mentioned generation, it is an object of the invention to provide a kind of bulk freighter hatch for counting overall strength completely
Coaming plate and ship mouthful stringers.
To achieve these goals, the technical scheme taken of the present invention is：
A kind of bulk freighter coaming for counting overall strength completely and ship mouthful stringers, wherein, including：Longitudinal coaming,
Longitudinal coaming is continuous along captain direction, and the elastic properties of materials yield limit of longitudinal coaming is relative to main deck
Elastic properties of materials yield limit improve 16%, the height of longitudinal coaming is decreased to below 600mm at transverse bulkhead；Cabin
Mouth stringers, the hatch side girder is highly less than conventional trunk stringers highly.
The above-mentioned bulk freighter hatch coaming for counting overall strength completely and ship mouthful stringers, wherein, near longitudinal hatch
The deck longitudinal of coaming plate becomes spacing using local.
The above-mentioned bulk freighter hatch coaming for counting overall strength completely and ship mouthful stringers, wherein, near longitudinal hatch
Turned on the deck longitudinal of coaming plate more than the main deck.
The above-mentioned bulk freighter hatch coaming for counting overall strength completely and ship mouthful stringers, wherein, longitudinal coaming exists
An inverted trapezoidal groove is formed at transverse bulkhead.
The above-mentioned bulk freighter hatch coaming for counting overall strength completely and ship mouthful stringers, wherein, it is adaptable to intermediate bulk carrier and
Minibulker.
As a result of above-mentioned technology, the good effect for being allowed to have compared with prior art is the present invention
(1) present invention can lift the hull beam rigidity of structure, improve fatigue life at hatch corner, improve hatch capacity,
And cargo hold area longitudinal member construction weight averagely mitigates more than 3%.

In accompanying drawing：1st, longitudinal coaming；11st, inverted trapezoidal groove；2nd, main deck；3rd, hatch side girder；4th, deck longitudinal.
Specific embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings, but not as limiting to the invention.
Fig. 1 is the schematic diagram of the bulk freighter coaming for counting overall strength completely of the invention and ship mouthful stringers, and Fig. 2 is this
The schematic diagram of bulk freighter coaming and ship mouthful stringers for counting overall strength completely of invention, refers to shown in Fig. 1, Fig. 2, shows
The bulk freighter coaming that counts overall strength completely and ship mouthful stringers of a kind of preferred embodiment, include：Longitudinal hatch coaming
Plate 1, longitudinal coaming 1 is continuous along captain direction.From from the point of view of control light weight, the material of longitudinal coaming 1
The elastic buckling limit improves 16% relative to the elastic properties of materials yield limit of main deck 2.The height of longitudinal coaming 1 is in horizontal cabin
Below 600mm is decreased at wall, is facilitated the movement of persons and mooring arrangement arrangement.
Additionally, in as preferred embodiment, bulk freighter coaming and ship mouthful stringers that overall strength is counted completely are also wrapped
Include：Hatch side girder 3, hatch side girder 3 is highly more smaller than conventional trunk stringers.The altitude range of conventional trunk stringers be 700mm extremely
800mm, and and improve after hatch side girder 3 reduce 200mm to 400mm compared to conventional trunk stringers.
Further, in as preferred embodiment, near the deck longitudinal of longitudinal coaming 1 or using between local change
Away to concede construction space.
Further, in as preferred embodiment, near longitudinal coaming 1 deck longitudinal or on turn to main first
Plate more than 2, to concede construction space.
Further, in as preferred embodiment, can also suitably increase near the deck longitudinal 4 and hatch in ship
The spacing of stringers 3, the scope of the spacing between increased deck longitudinal and hatch side girder is 100mm to 200mm.
Preferred embodiments of the present invention are the foregoing is only, embodiments of the present invention and protection model is not thereby limited
Enclose.
The present invention on the basis of the above also have mode is implemented as follows：
In further embodiment of the present invention, continuing with shown in Figure 1, longitudinal coaming 1 is formed at transverse bulkhead
One inverted trapezoidal groove 11.
In further embodiment of the present invention, because longitudinal coaming 1 is continuous along captain direction, therefore longitudinal hatch coaming
Plate 1 counts overall strength completely.
In further embodiment of the present invention, the material for illustrating longitudinal coaming 1 and main deck 2 is bent according to elasticity
The selection of the change of the limit is taken, such as material of main deck 2 is H36 steel, then longitudinal coaming 1 uses H47 steel；As main deck 2 is adopted
H32 steel is used, then longitudinal coaming 1 uses H40 steel.
In further embodiment of the present invention, the continuity Characteristics of longitudinal coaming 1 also improve the anti-of hatch side girder 3
Shear ability, therefore on the premise of local construction space is ensured, with the possibility for reducing the height of hatch side girder 3.
In further embodiment of the present invention, to improve contribution and increasing of the top side tank swash plate structure to the hull beam modulus of section
Plus hatch capacity, the height of hatch side girder 3 should be as small as possible.
In further embodiment of the present invention, bulk freighter coaming and ship mouthful stringers that overall strength is counted completely are applied to
Intermediate bulk carrier and minibulker.
Preferred embodiments of the present invention are the foregoing is only, embodiments of the present invention and protection model is not thereby limited
Enclose, to those skilled in the art, should can appreciate that done by all utilization description of the invention and diagramatic content
Scheme obtained by equivalent and obvious change, should be included in protection scope of the present invention.
