Problems solved by technology

[0004] This process provides a construction process for pre-installing grid plates in the process of building a certain ship in sections, and mainly solves the problem that the grid plates and the grid backing plates are connected by bolts; when the grid plates are hoisted into the side section, the installation space is small and the hoisting is difficult large; the included angle of the frame of the side section is small, and it is difficult to weld in a narrow space; the structure of the side is dense, and the painting cannot be carried out after the construction of the section in some areas is completed, etc. Technical difficulties

Embodiment Construction

[0026] The technical solution of the present invention is further described below in conjunction with specific embodiments:

[0027] Such as figure 1 As shown, a pre-installation process of a grid plate on a segment includes the following steps:

[0028] 1. Manufacture of side tire frame

[0029] The side section adopts the computerized tire frame, the column is installed now, and the linear tire board is installed later. The linear tire board is marked with the same letter as the position letter in the tire frame diagram, and the corresponding tire board is installed on the corresponding column position. A tire frame template is required.

[0030] 2. Assembling and welding of side section structure

[0031] Such as figure 2 As shown, the deck side plate is used as a section of the side part. After installation, the angle with the outer plate is small, and the fillet weld with the outer plate must be completed in advance, and then the upper opening of the grid plate 4 is ...

Abstract

The invention relates to a pre-assembling process of a grating plate on a subsection. The pre-assembling process comprises the following steps: S1, manufacturing a jig frame; S2, assembling and welding a board segment structure; S3, splicing and drilling the grating plates; S4, pre-hoisting the grating plate on the segmented broadside segments; S5, conducting side segment fire work back burning, weld joint flaw detection and coating; and S6, installing the grating plate. Through the construction process, the grating plate and the grating base plate are connected through fasteners such as bolts, and the technical problems that the grating plate is hoisted into the shipboard segment, the installation space is small, the hoisting difficulty is large, the included angle of a shipboard segmentframework is small, welding is difficult in a narrow space, the shipboard framework is dense, and coating cannot be conducted after segment construction in a local area is completed are solved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a pre-installation process of grid plates on sections. Background technique [0002] In the process of ship segmental construction, the grid plate is a special outfitting piece. Pre-installing the grid plate in the segment can improve the integrity of the segment, and the subsequent process can be moved forward, which is of great benefit to shorten the loading period of the dock. In addition, the construction environment in which the grille is installed in the side state of the ship section in the section is more convenient and safe than the normally closed construction environment in the loading stage, and the construction efficiency is also greatly improved. [0003] The positioning accuracy of the grid plate is high, the installation is difficult, and the construction process is complicated, involving multiple processes such as hull assembly and welding, grid drilling, gr...
