Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a combined support structure under the deck. Background Technology

[0002] With the increasing demand for compact ship design, designers are making more and more efficient use of space, especially in small and medium-sized ships, where the compact spatial layout poses certain challenges to structural design.

[0003] Typically, the width of the first and second decks of the superstructure is similar to the width of the ship. However, the outer walls of the superstructure are a certain distance from the hull side. Therefore, some pillars are installed on the lowest deck of the superstructure to support the loads extending onto the deck.

[0004] In this case, the support pillars are usually installed below the side where there are strong structural members such as longitudinal bulkheads or longitudinal girder. The deck load of the superstructure is relatively small, so round tube support pillars are generally chosen because they are lightweight and aesthetically pleasing. An elbow plate is installed on top of the support pillar and a pad plate is used below it. The support pillar, pad plate, elbow plate and adjacent structure are all corner welded.

[0005] In existing designs, when the spatial layout is very compact, considering factors such as passageways, equipment arrangement, piping system layout, and structural support, the only option is to reduce the size of the supporting structures. However, since these supporting structures often play a crucial supporting role, simply reducing their size can lead to structural damage. Utility Model Content

[0024] A support column 40 is provided between the upper deck 11 and the cantilever beam 20; the support column 40 is an I-beam. The support column is a profile, or the support column is welded from the web plate and the face plate of the support column.

[0025] The web 41 of the support column and the web 21 of the cantilever beam are located in the same plane; the top of the support column 40 and the panel 22 of the cantilever beam are fixedly connected.

[0026] Above the panel 22 of the cantilever beam is a support transition structure 15 to avoid stress concentration at the connection between the cantilever beam and the support.

[0027] The support transition structure 15 is a plate-shaped component. Support transition structures 15 are provided on both sides of the web 21 of the cantilever beam. The support transition structure is simultaneously fixed to the web and the panel of the cantilever beam.

[0028] Two support transition structures 15 are provided on each side of the web 21 of the cantilever beam; each support transition structure is located at the corresponding position of the support panel, and the support transition structure and the support panel located below the support transition structure are on the same plane.

[0029] The hatch coaming transverse elbow plate 33 is fixed to the strut 40; the hatch coaming transverse elbow plate 33 and the web plate 41 of the strut are located on the same plane.

[0030] A structural hole 34 is provided on the transverse elbow plate 33 of the hatch coaming to allow the piping system to pass through. A hole wall panel 35 is fixed to the wall of the structural hole 34. The piping system passes through the structural hole.

[0031] There is a gap between the strut 40 and the panel 32 of the longitudinal hatch coaming. The distance between the strut 40 and the panel 32 of the longitudinal hatch coaming is 100-200 mm. Preferably, the distance between the strut and the panel of the longitudinal hatch coaming is 100 mm.

[0032] An arc-shaped elbow plate 13 is provided between the upper deck 11 and the strut 40. The arc-shaped elbow plate 13 and the hatch coaming transverse elbow plate 33 are located on both sides of the strut 40, respectively.

A structural hole is opened in the middle of the hatch cofferdam transverse elbow plate, and a hole wall face plate is set on the hole wall to form a ring elbow plate, which ensures the passage space of the piping system while meeting the strength requirements of the hatch cofferdam transverse elbow plate. An arc-shaped elbow plate is installed on the other side of the lower end of the support column, which connects to the transverse elbow plate of the hatch coaming, as a transition structure. The arc shape reduces the space occupied by pedestrians.
