Embodiment

[0030] Embodiment: a kind of construction method of full-width type segment, such as Figure 2 to Figure 5 shown, including the following steps:

[0031] Step 1. Divide the full-width segmented bottom plate into the first bottom plate 1 and the second bottom plate 2 according to the existing plate seams. the most recent weld;

[0032] Step 2: Fabricate the tire frame 3, lay the first bottom panel on the tire frame, fix the first bottom panel on the tire frame 3, and perform tack welding on the gaps between the first bottom panels to form the first bottom panel 1 , laying the second base plate assembly on the tire frame, fixing the second base plate assembly on the tire frame 3, tacking the gap between the second base plate assembly to form the second base plate 2;

[0033] Step 3. Install the first rib 4 on the first bottom plate 1. The installation sequence of the first rib 4 in the left and right direction of the ship is to install gradually from the side close to the cent...

Abstract

The invention discloses an overall-width type segmental construction method and belongs to the technical field of ship construction. The method includes the following steps that firstly, a bottom board is divided into first bottom boards and second bottom boards; secondly, the first bottom boards and the second bottom boards are constructed on a molding bed; thirdly, components are installed on the first bottom boards, so that first segments are formed, and components are installed on the second bottom boards, so that second segments are formed; fourthly, the accuracy of the first bottom boards and the accuracy of the second bottom boards are measured and controlled; fifthly, flat angle welding and vertical angle welding are conducted in the first segments and the second segments; sixthly,the first segments and the second segments are combined to form overall-width type segments; and seventhly, all the overall-width type segments are turned over by 180 degrees, and flat angle weldingjoints in the overall-width type segments are burnt. In the method, each overall-width type segment is divided into one first segment and one second segment which are constructed through the same molding bed, and the phenomenon that the bottom board and an outer board are warped upwards due to welding can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of ship building, in particular to a full-width segmented building method. Background technique [0002] The full-width section refers to the bottom section of the ship's bow and stern. At both ends of the ship's bow and stern, the width of the ship changes significantly, and in the full-width section, the port and starboard sides are all in the same section Inside, the ribs and girders are installed closely, the welding density is high, and the stress of the segment is complicated. Because the outer plate of the full-width segment has a large line shape, it is necessary to use CO during welding. 2 For manual welding, the above reasons lead to large deformation of the full-width segment after welding, and both the bottom plate and the outer plate are prone to large precision deviations, and both ends of the bottom plate and both sides of the outer plate are prone to warping, resulting in It is difficult to ...
