Embodiment Construction

[0012] The assembly and welding of the ship plate unit in the present invention refers to the assembly and welding work between the bottom plate and the double-side webs and their corresponding longitudinal stiffeners, and between the top plate and its transverse stiffeners. Carried on. The specific process is as follows:

[0013] First of all, the assembly work of the ship plate unit is carried out. Before the work is carried out, the marking steel splines need to be prepared to prepare for the marking of the installation position.

[0014] The specific preparations for the scribed steel spline are as follows: the scribed steel spline of the base plate should have the theoretical width and width center line of the base plate, the width center line of the beam section, the theoretical length and the length dividing center line, the theoretical line and the thickness line of the component installation . Use the bottom plate to mark the steel spline to find out the width cente...

Abstract

The invention mainly discloses an assembling and welding process for a plate unit of a ship, and mainly relates to an assembling and welding process for a bottom plate and a corresponding longitudinal stiffening rib, for a bilateral web plate and a corresponding longitudinal stiffening rib as well as for a top plate and a transverse stiffening rib. The process is characterized by comprising the following steps of: before the bottom plate, the bilateral web plate, the longitudinal stiffening ribs, the top plate and the transverse stiffening rib of the plate unit are mounted, manufacturing a marking-off steel sample band in advance; marking off at a mounting position; assembling the plate unit according to the marking-off position; and welding the assembled and molded plate unit. The invention has the advantages that: when the plate unit is mounted, a steel plate sample band which is marked with scales is manufactured in advance, and then the plate unit is accurately positioned according to the steel plate sample band, so that the plate unit can be accurately mounted, and a good basis is provided for the accuracy of a plate unit framework.

Description

technical field [0001] The invention relates to a ship assembly and welding process, in particular to the joint assembly of ship plate units with bottom plate scribing steel splines, and automatic welding on a special tire frame. The special tire frame is set with convex curve anti-deformation, and has the functions of pressing, locking and swinging. Ensure accurate assembly of ship plate units, improve welding quality and welding efficiency, and effectively control welding deformation. Background technique [0002] The current plate unit assembly and welding process is that the assembler marks and installs stiffeners on the corresponding outer plate according to the size of the drawing, and then welds on the original flat tire frame. The disadvantages of the current plate unit assembly and welding process are: not using spline scribing will cause artificial scribing errors and scribing cumulative errors, component installation is not accurate, and it will bring inconvenien...
