Longitudinal bone cabin penetrating structure, longitudinal bone cabin penetrating structure assembling method and ship

Abstract

The invention discloses a longitudinal bone cabin penetrating structure, a longitudinal bone cabin penetrating structure assembling method and a ship. The longitudinal bone cabin penetrating structurecomprises a mounting base plate, a plurality of longitudinal bones and a traverse cabin well; the plurality of longitudinal bones are fixedly arranged on the mounting base plate at intervals, and corner welding grooves are formed in the side walls of the longitudinal bones; and a plurality of notches are formed in the end surface, in contact with the mounting base plate, of the transverse cabin wall, one notch corresponds to one corner welding groove in one longitudinal bone, and the transverse cabin wall is inserted and welded into the corner welding grooves of the longitudinal bones throughthe notches. According to the longitudinal bone cabin penetrating structure, the requirements of the rigidity and the strength of a ship body and the water tightness for the components to penetrate through a cabin are met, site construction, installation and welding are facilitated, and an extremely remarkable effect is achieved for controlling the overall deformation of the aluminum alloy ship body in the construction process.

Description

technical field [0001] The invention relates to the technical field of hull structures, in particular to a longitudinal bone penetrating structure, an assembly method of the longitudinal bone penetrating structure and a ship. Background technique [0002] In the process of building a ship mainly made of aluminum alloy, due to the particularity of aluminum alloy welding, it is greatly affected by the space environment. In the design, not only the rigidity of the hull and the safety of navigation must be considered, but also the transverse bulkhead. Tightness requirements and construction weldability operations. [0003] In the prior art, the structure adopted for crossing the watertight transverse bulkhead is spherical longitudinals and transverse bulkheads welded and fixed by stiffeners and reinforcing plates. The spherical longitudinals are made of aluminum alloy, and the spherical longitudinals include spherical heads. and ball back. Specifically, 100mm is taken at the f...

Problems solved by technology

Once holes need to be temporarily added to the structure in some areas, the existing mechanical cutting tools cannot be used at all. The hole opening at the ball head can only be done manually with a milling cutter. If the holes are deviated, the spherical longitudinals will encounter problems such as inability to insert, large gaps, etc., thus increasing the construction difficulties of assembly

[0006] Therefore, during the on-site construction at each stage, due to the excessive joints of spherical longitudinals (including multiple segments of spherical longitudinals) in the entire segmented structure, the welding workload is heavy, time-consuming, and the manufacturing process is complicated. It adds a lot of difficulty and workload to assembly and welding, which directly affects the construction efficiency and progress, and has a great impact on the deformation control in the entire sub-manufacturing process, and the construction quality cannot meet the precision requirements

Due to the extra allowance, it not only increases the cost of the overall construction, but also has a significant impact on the upturning of the longitudinal ends and the overall deformation after the segmental welding, and the manufacturing accuracy is difficult to control
