Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to an integrated ship wooden structure and a manufacturing and installation method thereof. Background Art

[0002] Hull stern logs are an appendage structure installed on the hull. They generally do not play a structural role and are mainly used to fill or transition the hull shape. The stern stern logs do not participate in the main load-bearing or structural support of the hull and are usually used to optimize the flow performance of the underwater part.

[0003] In existing technology, the aft hull stern stern is generally fusiform-shaped, with a streamlined structure that is tapered at the front and rear and wide in the middle. It is made of the same material as the hull and welded separately to the hull plating. Its tapered structure makes it difficult to manufacture and install, especially at the transition between the stern stern's bow and the hull bottom. Furthermore, the aft stern stern is large and has a dense internal structure. It not only contributes to the weight of the hull but also lacks connection to the hull, resulting in a considerable waste of space. Summary of the Invention
