Description
Technical field
The present invention relates to shipbuilding technical field more particularly to a kind of ship siding through hole and its open up method and ship
Oceangoing ship sectional construction technique.
Background technique
In Ship Design, in the liquid tanks such as ballast tank, fresh-water tank, fuel oil tank and oil cargo tank aggregate pass through non-watertight floor or
When other strong frames, existing through hole has full benefit plate or half-packaging to mend two kinds of forms of plate.Board-like through hole is mended entirely not to be able to satisfy
Flowing water requirement, needs to open a discharge orifice between every grade of vertical bone on floor, and the discharge orifice needs to reach bottom to guarantee not having
There is ponding.Half-packaging mends plate, and there are 30 to 50 millimeters of gaps between benefit plate and band plate, it is ensured that flowing water, but this shape
Formula is only used for connection area and tired region of less demanding.
Wherein, board-like through hole is mended entirely and although solves the problems, such as connection area and fatigue, but needs additionally to open up big
The discharge orifice of amount meets flowing water requirement, and this design has following several defects: first is that heavy workload is cut in blanking；First is that reaching
The discharge orifice at bottom causes continuously weld in the position, reduces welding efficiency；First is that being opened between aggregate in obliquity
Not in the minimum point of ponding, minimum point will cause a degree of ponding at through hole for discharge orifice present position.Half-packaging is mended
Plate through hole can solve flowing water problem, but also have following problems: first is that application range is small, the more demanding position of connection area
The form can not be used；First is that tired hot spot is more, fatigue problem position more outstanding can not use the form；First is that mending under plate
It holds close with a distance from band plate, there are problems that the constructional difficulties such as welding, polishing, cornerite, construction quality are difficult to ensure.
