Problems solved by technology

[0003] Although the current construction method can realize the installation of the superstructure of the ship, the segmented structure of the superstructure requires a variety of operations, and these operations are all carried out under the suspension state of the segmented structure, resulting in the It is extremely difficult, and requires a lot of working time, and the work efficiency is low; at the same time, long-term suspension of the segmented structure with a huge weight is likely to cause a large degree of deformation of the segmented structure, which will eventually affect the construction quality of the ship; Or, long-term high-altitude operations are not only difficult to construct, but also have great potential safety hazards; in addition, the suspension of segmented structures requires the use of lifting equipment such as cranes, and long-term suspension work will also occupy these Lifting equipment resources, resulting in other work can not be carried out smoothly

Embodiment Construction

[0016] Such as Figure 1-5 shown.

[0017] A construction technique for closing a ship superstructure without allowance, comprising the following steps:

[0018] A. Make a height reference line, including erecting a mark post 2 marked with a height M on the main hull 1, and at the same time, draw a height line N on the general section 3 of the superstructure, and the height of the height line N is consistent with the height M marked on the mark post ;Such as figure 1 shown;

[0019] B. Measure the position of the structure docked with the superstructure general section on the main hull; if figure 2 shown;

[0020] C, import the measured structural position data into processing software, such as the CAD software used in this embodiment, connect each structural position point with a spline curve according to the hull structure; as image 3 shown;

[0021] D, put the height reference line into the theoretical position of the hull coordinate system of step C, then measure t...

Abstract

Disclosed is an allowance-free joining construction process for the superstructure of a ship. Various structure positions for butt-joint of a main hull and a superstructure block are measured on the ground, then processing software is used for calculating and working out an allowance figure, allowance trimming work is completed on the ground, and after allowance trimming is completed, allowance-free joining butt-joint is conducted on the main hull and the superstructure block. According to the process, allowance trimming work is moved to be completed on the ground, so that operation difficulty is lowered, working efficiency is improved, protection of the structure of the superstructure and guarantee of the building quality of the ship are facilitated; and meanwhile, the security risk is effectively reduced, the use demand of auxiliary equipment such as hoisting equipment is lowered, and other related work is carried out smoothly.

Description

technical field [0001] The invention relates to a ship building process, in particular to a folding construction process for installing a superstructure without margin trimming on a ship. Background technique [0002] The superstructure of a ship refers to the part enclosed on the deck of the ship, mainly including cabins for various purposes, or forecastle, bridge, poop and various surrounding walls. These superstructures are mainly composed of skeleton structures made of profiles and wall panels made of panels. During construction, due to the huge volume and weight of these superstructures, it is necessary to hoist each segment onto the hull one by one, and then carry out related operations such as positioning, margin trimming, and assembly according to the actual situation. [0003] Although the current construction method can realize the installation of the superstructure of the ship, the segmented structure of the superstructure requires a variety of operations, and th...
