Description

TECHNICAL FIELD

[0001] The present application relates to the field of ship technology, in particular to a superstructure deck structure without strong frame. BACKGROUND

[0002] Large multi-deck continuous deck type ships (such as roll-on / roll-off ships, passenger ships, automobile transport ships, etc.), the center of gravity of the ship is high, the roll acceleration is large, and the transverse deformation of the ship structure is relatively severe in actual operation. The superstructure is usually located at the uppermost part of the ship body, which is the area with the largest transverse acceleration of such ships, and the requirement for resisting transverse deformation is high, and special consideration is needed in structural design.

[0003] The traditional deck arrangement is usually a combination of longitudinal frames and transverse strong frames, which resist transverse deformation through transverse strong frames. The design of transverse strong frames usually uses T-shaped section beams with high web height. This arrangement uses fewer transverse strong frames to resist transverse deformation, has lower reliability, and the overall structure is relatively heavy, and the transverse beam structure blocks part of the longitudinal piping arrangement.

[0004] Taking a passenger roll-on / roll-off ship as an example, from the longitudinal perspective, the passenger roll-on / roll-off ship has the structural characteristics of multi-deck continuous deck, with the lower part being the cargo hold area and the upper part being the superstructure area marked by the dashed line.

[0005] The existing typical superstructure deck structure is composed of deck plates, longitudinal materials, longitudinal girders, transverse strong frames, bulkheads, and pillars. The deck load is transmitted from the deck plate to the longitudinal material, and then from the longitudinal material to the transverse strong frame and the longitudinal girder, and then from the strong member to the bulkhead and the pillar, and finally to the lower ship structure.

[0006] The existing technical solutions have the following disadvantages:

[0007] 1. The arrangement uses fewer transverse strong frames to resist transverse deformation, and the transverse deformation resistance is weak.

[0008] 2. The number of strong members in the existing arrangement is large, and the overall structure is relatively heavy.

[0009] 3. The longitudinal piping of the ship needs to pass under the high T-shaped member, reducing the net height between decks. SUMMARY

[0010] The technical problem to be solved by the present application is to overcome the above-mentioned defects of the prior art, and to provide a superstructure deck structure without strong frame.

[0011] The present application solves the above technical problems by the following technical solutions:

[0012] The application discloses a superstructure deck structure without a strong frame, which comprises a deck plate, the bottom of the deck plate is fixed with a plurality of transversely distributed transverse materials, the transverse materials are spaced apart on the bottom of the deck plate, the bottom of the deck plate is fixed with a plurality of longitudinally distributed longitudinal girders, the longitudinal girders are spaced apart on the bottom of the deck plate, the bottom of the deck plate is provided with a plurality of support columns, the top of the support column is fixedly connected to the intersection of the longitudinal girders and the transverse materials, the bottom of the deck plate is not provided with a transverse strong frame, and the bottom of the deck plate is not provided with a longitudinal material.

[0013] The left side end and the right side end of the deck plate are provided with side walls.

[0014] The rear end of the deck plate is provided with a rear end wall.

[0015] The front end of the deck plate is provided with a front end wall.

[0016] The transverse materials are parallel to each other.

[0017] The longitudinal distance between adjacent transverse materials is the same.

[0018] The longitudinal girders are parallel to each other.

[0019] The transverse distance between adjacent longitudinal girders is the same.

[0020] The longitudinal girders are perpendicular to the transverse materials.

[0021] The transverse materials and the deck plate and the longitudinal girders and the deck plate are connected through welding.

[0022] The application has the advantages that the transverse uniform material arrangement of the superstructure deck structure without a strong frame can better prevent transverse deformation, the total longitudinal strength capacity of the multilayer continuous deck ship body is high, there is a large design redundancy, the longitudinal materials are omitted and do not affect the total longitudinal strength, the number of ship body strong components is reduced, the structure weight is reduced, the longitudinal piping of the ship can pass through the lower transverse materials, the net height between the decks is increased, the actual design height of the superstructure is further reduced, the structure weight is reduced, and the effect of reducing the gravity center of the ship is achieved.
