Problems solved by technology

There are a large number of door and window openings in the superstructure of large ships. When the door frame is installed in the later stage, the circle around the door and window openings needs to be polished and welded, which not only wastes material and labor costs, but also prolongs the construction period. The quality of grinding will also affect the welding quality. , and a large amount of dust left after grinding will affect the construction environment

Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing.

[0020] see figure 1 , the method for painting and retaining around the openings of the doors and windows of the large ship superstructure of the present invention comprises the following steps:

[0021] Step S1, after the completion of the subsection structure of the ship, determine the positions and areas that need to be painted at the opening positions of the doors and windows of the ship's superstructure; specifically, the 100mm range around the single side of the steel door opening is used as the position and areas that need to be painted. area, and one side of the steel door opening is a non-structural side. The 50mm range around both sides of the window opening is used as the position and area to be reserved for painting. Such as Figure 2-Figure 5 shown.

[0022] Step S2, sticking tape on the position and area to be reserved for painting;

[0023] Step S3, perfo...

Abstract

The invention discloses a method for coating retention around door and window open holes of a large ship superstructure. The method comprises the steps that after ship block structures are completed,positions and areas needing to be subjected to coating retention are determined at the door and window open holes of the ship superstructure; adhesive tape paper is pasted to the positions and areas needing to be subjected to coating retention; ship blocks are coated; and the adhesive tape paper is torn off, and the positions and areas needing to be subjected to coating retention are protected byworkshop primer. The labor cost is effectively lowered, and the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of ship painting technology, in particular to a method for retaining paint around openings in doors and windows of large ship superstructures. Background technique [0002] With the rapid development of the shipbuilding industry, many companies have been committed to building a first-class superstructure brand in the shipbuilding market. Therefore, it is necessary to shorten the shipbuilding cycle as much as possible while striving to achieve structural integrity. There are a large number of door and window openings in the superstructure of large ships. When the door frame is installed in the later stage, the circle around the door and window openings needs to be polished and then welded. This not only wastes material and labor costs, but also prolongs the construction period. The quality of grinding will also affect the welding quality. , and a large amount of dust left after grinding will affect the constr...
