Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

A typical multi-deck vessel comprises, from a side view, an inner bottom plate, a lower deck, an upper deck 2 and a superstructure 3, each deck structure. The upper deck 2 is used as a boundary, the lower part of the upper deck is provided with a main ship body 1 structure, and the upper part of the upper deck is provided with an superstructure 3 area. According to the characteristics of the total longitudinal bending moment of the hull beam, the vertical total bending moment of the middle area of the ship is usually the largest, and meanwhile, the sudden change of the cross section of the hull beam is generated due to the termination of the upper building, so that the stress concentration phenomenon at the joint of the root of the lowermost layer of the upper building and a deck is caused.

According to one or more embodiments, a superstructure negative corner structure is disclosed, as shown in fig. 1 and 2, comprising a main hull 1, an upper deck 2 and a superstructure 3 located on the upper deck 2, wherein a negative corner 4 is provided at a corner of a lowermost floor of the superstructure 3, the negative corner 4 is composed of a first side wall 41 and a second side wall 42, the first side wall 41 is formed by moving a recess of the lowermost side wall to the interior of the superstructure 3, and the second side wall 42 is formed by moving a recess of the lowermost end wall to the interior of the superstructure 3. The first side wall 41 is in particular connected perpendicularly to the end wall of the superstructure 3 and the second side wall 42 is connected perpendicularly to the side wall of the superstructure 3.

The first side wall 41 and the second side wall 42 are in arc transition connection, specifically, arc transition is formed between the connection part of the first side wall and the ship upper deck 2 and between the first side wall and the deck of the superstructure 3, so that the phenomenon of stress concentration is eliminated, and the effect of stress concentration caused by total longitudinal deformation in the existing design is better solved.

Through the arrangement of the negative corner 4, the thickness of the reinforcing plate is smaller as a whole, the welding construction process is simpler, more convenient and more reliable, and the risk of fatigue damage is smaller. Meanwhile, the thick and heavy large toggle plate component is not needed to extend at the root of the side wall to enable the structure to be smoothly transited, the used structural plates are fewer, the structural weight of the ship body is reduced, more channels 2 of the upper deck are not occupied, the passability of the channels 2 of the upper deck is increased, and the use is more convenient.

A support column 43 is further arranged at the negative corner 4, the support column 43 is supported between the ship upper deck 2 and the superstructure 3 deck, and is specifically fixedly arranged at the extending intersection of the side wall and the end wall of the superstructure 3 to support the superstructure 3, so that the whole structure is more stable and reliable.

Preferably, the negative corners 4 are disposed at two corners of the lowest layer of the superstructure 3 in the midship area, and structural improvement is performed at the corners of the superstructure 3 in the midship area, so as to optimize the structure and reliability of the ship as a whole.

In order to solve the stress concentration phenomenon at the joint of the root of the lowest layer of the upper building and a deck, the conventional method generally increases the local plate thickness and extends a large toggle plate at the root of the side wall to enable the structure to be smoothly transited, but the effect of controlling the stress concentration phenomenon caused by total longitudinal deformation by the conventional design scheme is not ideal. More reinforcement structures need to be added around the stress concentration areas. Through the structural design of this application, can make the reinforcing plate thick whole little, welding construction technology is simple and convenient reliable, and fatigue damage risk is less. Meanwhile, the scheme integrally uses fewer structural plates, so that the weight of the hull structure is reduced, the passability of the upper deck 2 channels is increased, the use is more convenient, and the effect is better on solving the problem of stress concentration caused by total longitudinal deformation.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
