Problems solved by technology

This method not only wastes materials, but also wastes labor. Therefore, one of the core technologies in precision control technology is to replace the margin with compensation
However, at present, there is no set of standards for adding compensation amount suitable for shipyards in China, so the accuracy control method based on adding compensation amount cannot be implemented.

Embodiment 1

[0044] figure 1 What is shown is the addition and placement of the compensation amount for the assembly of the double bottom discontinuous ribs in the cargo hold and engine room of Embodiment 1.

[0045] The fixed value of the assembly compensation amount is added to the assembly compensation amount at the intermittent floor of the double bottom of the cargo hold and engine room, which is -1.

Embodiment 2

[0047] figure 2 What is shown is the addition and placement of the compensation amount for the assembly of rib reinforcements in Embodiment 2.

[0048] The assembly compensation amount of the rib reinforcement is added with the fixed value of the assembly compensation amount, which is -1.

Embodiment 3

[0050] image 3 What is shown is the addition of compensation amount for bracket assembly in Example 3.

[0051] The bracket assembly compensation is added with the fixed value of the assembly compensation, which is -1.

Abstract

This invention relates to shipbuilding technique field, particular to compensation quantity overplus value method that selects corresponding value for different welding method and thickness. The determination for compensation value of different inner frame and overplus value of welding deflection comprises following steps: the contraction compensation of welding line is same for whatever manual welding, CO2 pad welding or both sides auto welding; the compensation value for unilateral contraction value relates with plate thickness and accords the thin plate thickness when thick plate butt joins with thin plate; for manual welding, CO2 fillet welding, the compensation value varieties with thickness of fillet and plate; the compensation for cargo hold, double-layer bottom intercostal floor of engineer room, floor and its reinforcement material, keel-line, and vertical baffle plate, is minus one; the compensation value of prismatic plate, bracket welding, welding deformation of engineer room double bottom when segment and inverse-building, welding deformation of engineer room big frame, relates with parameters of B, L, and H. This invention uses compensation value instead of surplus, and decreases the amend and straightening.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for adding and releasing compensation values ​​in the shipbuilding technology. Background technique [0002] Shipbuilding precision control is one of the key technologies to implement the modern shipbuilding model, and it is the technical guarantee to shorten the construction period, ensure the construction quality, and reduce the cost of shipbuilding. [0003] At present, the method of adding margin is widely used at home and abroad to implement precision control. The margin is to leave a margin of 50mm or more at the ends of components such as plates and longitudinals, and measure them after processing. According to the theory Trim excess material to size. This method not only wastes materials but also wastes labor. Therefore, one of the core technologies in precision control technology is to replace the margin with the compensation amount...
