Technical Field
The invention relates to the technical field of ships, in particular to a novel vertical groove type bulkhead type structure.
Background
Bulk carriers are divided into several cargo holds for loading cargo respectively, and the vertical tank bulkheads are used for separating the cargo holds of the ship body and are usually formed by connecting pressed plane steel plates in a welding or bending mode.
Compared with a plane cabin wall plate, the traditional vertical groove type cabin wall does not need to be additionally provided with aggregates, so that the workload of cabin sweeping is reduced, and the structure is cleaner and tidier. However, as an improvement to the planar bulkhead plate, there are some drawbacks, as listed below:
(1) because of the adoption of the combination body of the plane plate, in order to ensure the requirement on the strength, a thicker plate thickness is often needed to ensure the structural strength.
(2) The crossed parts of the groove strip web plate, the panel and the bottom plate are easy to accumulate goods and are not easy to clean.
(3) The welding quality of the intersection points of the three welding lines is not easy to be ensured. Three welds, respectively: the full penetration welding of the groove strip web and the groove strip panel is realized; butt welding the groove strip web plate and the unloading plate; butt welding of the bottom pier sloping plate and the unloading plate. Because the welding is relatively close, and the structure is complicated, welding quality is difficult to obtain the assurance.

FIG. 2 is a schematic sectional view taken along line A-A in FIG. 1.
Detailed Description
The present invention will be more clearly and completely described in the following description of preferred embodiments, taken in conjunction with the accompanying drawings.
As shown in fig. 1 and 2, a novel vertical channel bulkhead style structure includes a bulkhead body 20 disposed between a top pier bottom plate 11 and a bottom pier top plate 12.
The top of the groove strip 30 is fixedly connected with the top pier bottom plate 11; the bottom of the channel strip 30 is fixedly connected to the bottom pier top plate 12. The bottom of the groove strip is connected with the top plate of the bottom pier in a welding manner, and the top of the groove strip is connected with the bottom plate of the top pier in a welding manner.
The bulkhead body 20 is composed of a plurality of groove strips 30 which are connected in sequence from left to right; the ends of adjacent groove strips are connected in a tangential manner.
The cross-section of the channel strip 30 is arcuate. Preferably, the cross section of the groove strip is a semicircular arc.
The notches of adjacent grooves 30 face in opposite directions.
The grooves surrounded by the groove strips are vertically distributed; the connecting lines between adjacent groove bars 30 are vertically distributed.
The bulkhead body 20 is wavy in cross-section.
The connecting line of the arc midpoints of all the groove strips positioned on one side of the bulkhead body is parallel to the connecting line of the arc midpoints of all the groove strips positioned on the other side of the bulkhead body.
The end of the bulkhead body 20 and the outboard ship plate on the side are connected by a flat plate 40. In the present embodiment, both ends of the bulkhead body 20 are provided with flat plates 40, and the bulkhead body is connected to a port-side ship outer plate 41 and a starboard-side ship outer plate 42 via the two flat plates, respectively.
In this embodiment, adjacent groove bars are connected by welding.
In other embodiments, the bulkhead body is integrally formed.
According to the invention, a plurality of groove strips with arc-shaped cross sections are arranged between the bottom plate of the top pier and the top plate of the bottom pier, and a complete wave-shaped vertical groove-shaped bulkhead body is formed among the groove strips in a welding mode, so that the vertical groove-shaped bulkhead of the bulk cargo ship is optimized into a wave-shaped groove strip assembly from a traditional flat plate type groove strip assembly.
The invention adopts a wavy line type bulkhead body; compared with a plane plate, the corrugated plate has stronger bearing capacity, and can adopt thinner plate thickness compared with the traditional tank bulkhead under the condition of bearing the same load, thereby saving the weight of the ship body.
The corrugated bulkhead body is adopted, dead corners cannot be generated at the intersection of the bottom of the corrugated bulkhead body and other plates, the corrugated bulkhead body and other plates are connected smoothly, and the corrugated bulkhead body is not easy to accumulate goods and convenient to sweep a cabin.
Three welding seams exist in the traditional groove-shaped bulkhead, which are respectively as follows: the full penetration welding of the groove strip web and the groove strip panel is realized; butt welding the groove strip web plate and the unloading plate; butt welding of the bottom pier sloping plate and the unloading plate. The invention has no node with overlapped welding seams, and has lower requirements on welding process compared with the traditional tank type bulkhead.
The main body of the invention adopts a smoother structure, so the fatigue strength of the tank bulkhead can be improved.
The ship outer plate is connected with the traditional flat plate structure close to the side, so that the stability of the structure is ensured, and the construction is more convenient.
The invention can obviously save the weight of the tank type bulkhead structure, increase the structural strength, avoid goods accumulation and facilitate cleaning the tank, does not have a plurality of nodes with overlapped welding seams, has lower requirements on the welding process compared with the traditional tank type bulkhead, and can also improve the fatigue strength of the tank type bulkhead because of no fatigue hot spot in the traditional tank type bulkhead design.
