Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a pier device for ship section construction. Background Technology

[0002] In the segmented construction of ships and marine engineering structures, piers are crucial tooling facilities used to support and secure the segments. Traditional piers are mostly made of pure concrete, which presents the following problems: (1) During hoisting, transportation and use, collisions are likely to occur, resulting in damage to the edges and corners or even structural cracks, and the service life is short; (2) For sections with complex curved surfaces such as bilges and sides, pure concrete piers cannot provide effective support and rigid fixation, posing safety hazards; (3) Concrete piers are inconvenient to lift and transport, and usually require forklifts. However, gantry cranes are difficult to lift and transport, resulting in low efficiency and easy damage.

[0003] Therefore, there is an urgent need to develop a new type of pier device that combines collision resistance, easy hoisting, and adaptability to rigid fixing of linear segments, so as to improve the safety, efficiency, and reusability of equipment and facilities in segmented construction.

[0030] The concrete cement pier 2 has two oppositely arranged pier forklift insertion holes 2.1 on its front side. The pier forklift insertion holes 2.1 penetrate the concrete cement pier 2 to facilitate forklift handling.

[0031] In this embodiment 1, a ship pier device for segmented construction is used in the non-straight area of ​​the linear segment 4. A supporting structural member 3 is used to support and connect the linear segment 4 and the pier device. The supporting structural member 3 can be a round pipe, H-beam, or other supporting member.

The concrete pier is provided with two pier loader insertion holes.

[0039] This utility model discloses a ship pier device for segmented ship construction, used in non-straight areas of linear segments. To ensure that the linear segment does not tilt during the overall assembly or final assembly stage, the new composite pier and segment are rigidly fixed by welding using supporting structural components such as round pipes or H-beams. The lower part of the aforementioned round pipes or H-beams is preferably located and welded to the middle area of ​​the top of the new composite steel-concrete pier, while the upper part of the round pipes or H-beams is preferably located and welded to the strong structure at the intersection of the outer plate longitudinal ribs and solid rib plate structural frames of the linear segment.

[0040] like Figure 6 As shown, the straight section can utilize either the new composite pier or conventional cement concrete piers. There is no need for welding between the pier and the bottom outer plate of the section; only wooden blocks are needed to ensure that the outer plate of the section is not damaged.

[0041] This utility model discloses a pier device for ship section construction, belonging to the field of shipbuilding tooling technology. The device includes a concrete pier body and an outer steel frame covering it.
