Embodiment Construction

[0046] The present invention will be more clearly and completely described below by means of embodiments and in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0047] Such as figure 1 and figure 2 As shown, the present invention discloses a hull frame device 1, which includes a main board 2 and a first member board 3, the bottom surface of the first member board 3 is connected to the main board 2, and one end of the first member board 3 facing the main board 2 is provided with a There is a first notch 31 located at the end of the first component plate 3 .

[0048] In this embodiment, the first component plate 3 is in the shape of a thin plate. When it is placed vertically, its orientation will be described. The two wide sides of the first component plate 3 are the sides, and the narrow surfaces on the left and right sides are the ends. The bottom surface of the first component plate 3 is welded to the m...

Abstract

The invention discloses a hull panel frame device and a welding method for the hull panel frame device. The hull panel frame device includes a main board and a first member board, the bottom surface of the first member board is connected to the main board, and the first member board is connected to the main board. One end of a component plate facing the main plate is provided with a first notch, and the first notch is located at an end of the first component plate. The welding method of the hull plate frame device includes the following steps: S1, cutting out a corner of the first component plate as a first arc-shaped gap, and reserving a first raised portion in the first gap; S2. Welding the bottom surfaces of the first component plate and the second component plate to the main board; S3. Welding the end surface of the first component plate with the first notch to one side of the second component plate or welding on the end face of the second member plate. By arranging notches at the T-shaped intersection positions of the hull plate frame device, the stress concentration at this position during welding can be effectively avoided, and the connection strength of the hull plate frame device can be improved.

Description

technical field [0001] The invention relates to a ship, in particular to a hull panel frame device and a welding method for the hull panel frame device. Background technique [0002] At present, in the process of shipbuilding, T-shaped intersections of multiple hull grillage structures are formed inside the ship. The T-shaped intersections of this hull grillage structure often form corners, so the corners will form T-shaped intersections. If this type of fillet weld is welded by common methods, stress concentration will occur at the weld position of the steel plate. General stress concentration will cause cracks on the steel plate, and severe stress concentration will cause the steel plate to break. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hull grillage device and a welding method for the hull grillage device in order to overcome the defect of stress concentration after welding T-shaped cross fillet weld...
