Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The outer plate structure 3 and the deck structure 4 form a shipboard outer plate segmented structure and comprise a certain amount of inner structural materials, and the shipboard outer plate segmented structure is characterized in that the outer plate structure 3 exceeds the deck structure 4, the size of the exceeding flange is large, a lifting lug in a conventional common shape is arranged on a deck plane and interferes with the flange of the outer plate, so the lifting lug can only be arranged outside the outer plate structure, and based on the structure, as shown in fig. 1, 3 and 4, the embodiment of the invention discloses a special lifting lug for ship outer plate and deck combination segmentation, which comprises a lifting lug 1, an upper reinforcing member 2 and a lower reinforcing member 5, wherein the lifting lug main body comprises a lifting lug main body part and a hanger installation part, the bottom of the hanger installation part is arranged on the deck structure 4, the bottom of the lifting lug main body part is higher than the height of the outer plate structure 3 exceeding the flange of the deck structure, the upper reinforcing member is fixed above the deck structure and connected with the hanger installation part, the lower reinforcing member is fixed below the deck structure, and the lower reinforcing member is also connected with the outer plate structure.
As a preferred embodiment, in order to ensure enough welding strength, the specially-made lifting lug and the deck structure are welded in a groove-opening mode, and the height of the specially-made lifting lug and the size of the extending outer plate are adjusted according to the size of the outer plate higher than the flash of the deck, so that the interference with the flash of the outer plate is avoided. In the embodiment, the plate thickness of the special lifting lug is the same as that of a common lifting lug with the same specification.
The upper reinforcing part comprises a first support plate and a second support plate, the specifications of the first support plate and the second support plate are the same, and the heights of the first support plate and the second support plate are smaller than the height of the hanger installation part.
