Description
Technical Field
The invention belongs to the field of ship structure design and construction, and particularly relates to a ship cargo hold structure and a ship.
Background
The structural arrangement of the double-layer bottom of the cargo hold of the existing medium and large-sized chemical carrier is shown in figure 1, the forefront rib plate and the secondary front rib plate are arranged in the double-layer bottom right below the transverse bulkhead of the cargo hold and are respectively aligned with the straight side plate of the bottom stool and the inclined side plate of the bottom stool, other rib plates are arranged at equal intervals, the distance between the forefront rib plate and the secondary front rib plate is smaller than the distance between other rib plates, and the secondary front rib plate and all other rib plates are vertically arranged. In the double-layer bottom structure, a single longitudinal rib part is long, penetrates through a plurality of rib plates, and an outer plate longitudinal rib is connected with the outer plate in a welded mode, and is connected with the rib plates and reinforcing materials, toggle plates and the like on the rib plates in a welded mode when penetrating through the rib plates.
For convenient construction, the outer plate longitudinal bones are generally of the same specification at different positions as much as possible, so that butt joint between different specifications is reduced. For the double bottom structure, the cargo hold bottom may slightly bulge downward or sag upward due to the pressure difference due to the imbalance of cargo pressure of the cargo hold and external seawater pressure. While there is little deformation at the transverse bulkhead due to the transverse bulkhead structure being sufficiently rigid. This difference in deformation results in an additional load being applied to the outer longitudinal web portion between the minor anterior rib and the posterior-most rib, which load primarily affects the fatigue strength of the outer longitudinal web. The gauge and size of the outer skin bone material is most often determined by fatigue strength. When the longitudinal rib parts between other rib plates just meet the strength requirement, the longitudinal rib strength between the secondary front rib plate and the nearest rib plate behind the secondary front rib plate is insufficient, and reinforcing treatment is needed for ensuring the structural safety. The reinforcement process generally employs the addition of toggle plates and the addition of rib reinforcement to reduce the unsupported length of the longitudinal bones therein, thereby reducing the requirements for the specifications of the longitudinal bones therein so that the same specifications can be used at other locations. However, the method increases the weight of the structure, increases the construction time and the construction cost, and has the problems of large material waste, large included angle between the secondary front rib plate and the inclined side plate of the bottom stool, affected load transmission effectiveness between the secondary front rib plate and the inclined side plate of the bottom stool, stress concentration at the connecting part and poor safety and reliability because of small span of the longitudinal rib part between the forefront rib plate and the secondary front rib plate and large strength margin.

The distance from the lower edge of the secondary front rib plate to the adjacent common rib plate is smaller than the distance between other common rib plates; the distance between the lower ends of the inclined side plates of the bottom stool and the lower ends of the straight side plates of the bottom stool is smaller than the distance between the common rib plates; the distance from the lower edge of the forefront rib plate to the lower edge of the secondary front rib plate is smaller than or equal to the distance between the common rib plates. The inclination angle of the secondary front rib plate is consistent with the inclination side plate of the bottom stool or floats up and down by a smaller angle.
As a further preferable mode of the present invention, the distance from the lower edge of the secondary front rib to the normal rib adjacent thereto is smaller than the distance between the other normal ribs by 0.2m-1m. The distance between the lower ends of the inclined side plates of the bottom stool and the lower ends of the straight side plates of the bottom stool is 50-90% of the distance between the common rib plates. The distance from the lower edge of the forefront rib plate to the lower edge of the secondary front rib plate is 95-100% of the distance between the common rib plates. The inclination angle of the secondary front rib plate is 0-45 degrees.
The following further describes, by way of example, a cargo hold structure for a ship according to the present invention, in this embodiment: the distance from the lower edge of the secondary front rib plate to the adjacent common rib plate is 0.2m smaller than the distance between other common rib plates, and the distance from the lower end of the inclined side plate of the bottom stool to the lower end of the straight side plate of the bottom stool is 50% of the distance between the common rib plates. The distance from the lower edge of the forefront rib plate to the lower edge of the secondary front rib plate is equal to the distance between the common rib plates. The inclination angle of the secondary front rib plate is consistent with that of the inclined side plate of the bottom stool and is in the same plane. When the auxiliary structure for reinforcing the connection between the rib plate and the longitudinal rib is arranged on the common rib plate, the auxiliary structure on the common rib plate adjacent to the secondary front rib plate is the same as that on other common rib plates, and the auxiliary structure can comprise a strengthening material and a toggle plate, or the auxiliary structure can not be arranged.
In this embodiment, the corresponding minor front rib under the bench gusset is disposed obliquely. The inclined direction is the same as the inclined direction of the inclined side plate of the stool, the upper end of the secondary front rib plate is connected with the inner bottom plate, the inclined side plate of the stool is arranged above the inner bottom plate at the joint, and the upper edge position of the secondary front rib plate corresponds to the lower edge position of the inclined side plate of the stool. When the inclination angles of the front rib plate and the bottom stool are the same, the plane of the front rib plate and the plane of the bottom stool inclined side plate are the same. When the inclination angles are different, the inclination angles are not in the same plane. The distance from the upper edge of the secondary front rib plate to the rear rib plate is the same as the distance between other common rib plates, and the distance from the lower edge of the secondary front rib plate to the rear rib plate is smaller than the distance between other common rib plates. The width of the lower end of the transverse bulkhead of the cargo hold, namely the distance from the lower end of the inclined side plate of the bottom stool to the lower end of the straight side plate of the bottom stool, is smaller than the distance between the common rib plates, so that the horizontal distance between the upper edge of the secondary front rib plate and the forefront rib plate is smaller than the distance between the common rib plates, and the distance from the lower edge of the secondary front rib plate to the forefront rib plate is measured forward horizontally and is equal to the distance between the common rib plates. When the auxiliary structure for reinforcing the connection between the rib plate and the longitudinal rib is arranged on the common rib plate, the auxiliary structure on the nearest rib plate behind the secondary front rib plate is the same as that on other common rib plates, and the auxiliary structures can be a strengthening material, a toggle plate and the like, and the auxiliary structures can not be arranged, namely the auxiliary structures are kept consistent. The auxiliary structure of the secondary front rib plate is similar to the common rib plate, but the specific shape of the auxiliary structure is different due to the inclined arrangement, and compared with the common rib plate, parts are not added.
In this embodiment, the outer longitudinal rib is located between the minor front rib and the nearest rib behind the minor front rib, and the sea water load borne by the outer longitudinal rib is correspondingly reduced due to the reduced span, and the total load borne by the outer longitudinal rib is reduced compared with the conventional cargo hold structure due to the additional load brought by the position close to the transverse bulkhead, so that the fatigue strength is greatly improved, and the strength requirement can be met by adopting the outer longitudinal rib with the same specification as that of the longitudinal rib at other positions in the case that the front and rear ends of the outer longitudinal rib are not reinforced. The outer plate longitudinal rib part between the secondary front rib plate and the forefront rib plate has the span basically equivalent to that of the longitudinal rib between the common rib plates, so that the strength requirement is basically equivalent, the strength is not obviously excessive when the same specification is used, and the material waste is reduced.
When the outer plate longitudinal rib with the same specification is adopted, the existing cargo hold structure has obvious excessive strength at the longitudinal rib part between the secondary front rib plate and the forefront rib plate, and the strength at the longitudinal rib part between the secondary front rib plate and the nearest common rib plate behind the secondary front rib plate is insufficient to be reinforced. According to the embodiment, the distances between the two spans are adjusted according to the actual strength requirement, so that the two spans reach an equilibrium state, the stress is more uniform, the safety is better, structural parts are reduced, the weight is lighter, and the material cost and the processing cost are reduced.
The secondary front rib plate that this embodiment set up in the oblique curb plate below of end bench is the slope and arranges, compares with current cargo hold structure, and secondary front rib plate does not have contained angle or deflection angle very little with the oblique curb plate of end bench. When the inclined side plate of the bottom stool transfers load to the front rib plate downwards, the path is smoother, and the stress concentration coefficient is reduced. The strength requirements for the structures at the intersecting positions of the secondary front rib plate, the inclined side plate of the stool and the inner bottom plate and the structures near the intersecting points are reduced, and the safety of the structures is improved. The foremost rib and the minor front rib serve as support structures and foundations below the transverse bulkhead. Compared with the existing cargo hold structure, the width of the bottommost end of the foundation is enlarged, the structure is firmer, and the bearing capacity of the transverse bulkhead is improved. If the bearing requirement is unchanged, the specification and the size of the transverse bulkhead structure can be properly reduced, so that the structure weight is further reduced, the rigidity of the transverse bulkhead structure is better, and the vibration level of the transverse bulkhead can be improved.
In this embodiment, the use of the reinforcing structure is reduced, the cargo hold structure is lighter in weight, and under the same conditions, the weight of the cargo loadable by the ship is greater, and the operating economy of the ship is better.
By adopting the cargo hold structure provided by the technical scheme of the invention, each outer plate longitudinal rib is arranged at the transverse bulkhead, one reinforcing material and one reinforcing toggle plate can be reduced, the reinforcing material comprises 2-3 parts, the common reinforcing material is used for replacing the reinforcing material, the common reinforcing material only comprises one part, the reinforcing material and the toggle plate are compared, the number of the 2-3 parts is reduced, 30 outer plate longitudinal ribs are arranged at each transverse bulkhead, the whole ship is calculated according to 8 transverse bulkheads, the total weight of the whole ship is reduced by 600 parts, and the total weight of the whole ship is reduced by about 15 tons due to the cargo hold structure in the technical scheme of the invention. And the reduction area of each outer plate longitudinal bone is 6 square centimeters according to the outer plate longitudinal bone specification reduction calculation, and the total of 30 outer plate longitudinal bones are calculated according to the length of 130 meters, so that the weight of the whole ship is reduced by about 18 tons.
