Description

Technical Field

[0001] The utility model belongs to the technical field of shipbuilding, and in particular relates to a vertical truss panel structure which also serves as a guide rail in a car roll-on / roll-off ship. Background Art

[0002] In order to meet various types of loading, improve loading and unloading efficiency, ensure the number of vehicles loaded and meet the requirements of loading vehicles with higher bodies, car ro-ro ships are usually designed with multiple layers of movable decks. The movable deck is generally set between two fixed decks and lifted by a jacking vehicle. The hull structure in the four corners of the movable deck has additional recessed wall boxes to set semi-automatic support seats, fixed support seats and limit guide plates. The semi-automatic support seats and fixed support seats are welded to the web of the vertical truss. When the vertical truss panel also serves as a guide rail, the limit guide plate is clamped on the edge of the vertical truss panel and rises with the movable deck. In conventional designs, the top toe end of the vertical truss panel is enlarged and welded to the crossbeam panel, or the top end of the vertical truss panel is separated from the air and beveled. However, the enlargement of the toe end and the bevel of the end will change the trajectory of the guide rail, which cannot meet the vertical lifting requirements of the movable deck, resulting in a reduction in the lifting height of the movable deck.
