By inserting a hexagonal wrench into the fastening bolt and rotating the fastening bolt, the fastening bolt can be loosened from the threaded groove column. At this time, the telescopic column can be partially pulled out of the sleeve column, and then the head of the telescopic column is welded to the main deck to adapt to main decks of different sizes and thicknesses;

[0018] 3. The longitudinal watertight bulkhead of the cruise hub station is welded to the deck through a tree branch structure.

At the same time, the telescopic column can be pulled out of the sleeve column to effectively transfer the non-uniform loads transmitted from different areas of the main deck.
