Description

Jointed board marking method

Technical Field

The invention relates to the technical field of ship construction, in particular to a jointed board marking method.

Background

In the ship building process, the jointed boards are front-end processes of sectional manufacturing. The fabricated panels are assembled into a splicing section, and then other structures are installed on the splicing section or a plurality of splicing sections are assembled into corresponding structures of the ship.

In order to ensure the accuracy of mounting other structures on the splicing sections and assembling a plurality of splicing sections into a whole, the splicing plates processed in sections need to be scribed for size control. The existing scribing for jointed boards is to make a cross line at the center of the jointed board, measure preset distances to two sides respectively by taking the cross line as a reference and scribe. Because the distance is measured and errors exist in the scribing process, twice measurement and scribing are needed when one line is drawn by adopting the cross scribing method, the errors are doubled, and the scribing accuracy is low. In addition, the cross-shaped scribing method is used for scribing different jointed boards, so that the scribing reference is not uniform, and the condition of poor integral squareness and even distortion easily occurs after the jointed boards are assembled.

Therefore, a method for marking jointed boards is needed to solve the above problems.
