Description
Technical Field
[0001] The present invention relates to the field of shipbuilding, and particularly to a connection structure and a connection method for the outer hull plate and the deck of a ship. Background Art
[0002] With the gradually increasing attention to the characteristics of composite materials such as light weight, high strength, corrosion resistance, and fatigue resistance, the materials used in some medium and small ships are gradually changing from traditional metal materials to composite materials. During the sea voyage, a ship needs to withstand loads such as hydrostatic pressure and wave impact force. As an important structure affecting the longitudinal strength of the hull, the connection between the deck and the outer hull plate should ensure relatively strict strength and stiffness.
[0003] At present, some small composite ships can be connected by integral molding. However, for larger ships, the deck and the outer hull plate are formed separately, and a connection structure and a connection method must be designed. Commonly used composite connection methods include adhesive bonding and mechanical connection. Mechanical connection inevitably requires drilling holes, which causes stress concentration and damages the composite materials. In comparison, adhesive bonding has better connection efficiency and fatigue resistance, but lower peel strength. Therefore, a reasonable connection structure and connection method to meet the safe and non-destructive connection requirements between the outer hull plate and the deck of a composite ship is a key technical problem that urgently needs to be solved in the field of composite ship connection.

[0025] Through the direct adhesive bonding of the outer hull plate body 100 and the deck body 200, the adhesive bonding of the base body 300 and the outer hull plate body 100, and the adhesive bonding of the card slot 310 of the base body 300 and the rib 110 on the deck body 200, the connection between the outer hull plate body 100 and the deck body 200 can be realized only by the adhesive bonding method, improving the connection efficiency and meeting the connection requirement of no damage; at the same time, the base body 300 can play a limiting role, and the cooperation between the card slot 310 and the rib 110 on the deck body 200 enables the load on the deck body 200 to be transmitted to the main hull structure with stronger load-bearing capacity, enhancing the safety of the connection between the outer hull plate body 100 and the deck body 200.
[0026] At least one rib 110 is provided on the end face of the outer hull plate body 100, and one end of the rib 110 located on the end face of the outer hull plate body 100 is adhesively bonded to the base body 300. In this embodiment,
