Embodiment Construction

[0013] The present invention changes the construction method of the lower side section of the existing shipbuilding technology, such as Figure 4 Comparing with Fig. 2, it can be seen that the present invention pre-installs the longitudinal hatch coaming 3 and the side stand column 4 in advance in the stage of subsection construction of the side of the ship. So as to achieve the purpose of improving the overall shipbuilding efficiency. In order to achieve the above object, it is necessary to strictly control the assembly accuracy of the longitudinal hatch coaming and the side stand column, for this reason the present invention provides the following scheme:

[0014] First of all, as shown in Figure 1, when the tire frame is manufactured (before welding and assembly), anti-deformation is added to the longitudinal hatch coaming 3 to control the welding deformation, so that the hatch coaming is in a horizontal state after welding, so as to ensure the level degree, straightness. ...

Abstract

The invention relates to the field of marine engineering, and discloses an integrated manufacturing method for a shipboard segment in shipbuilding. At the stage of manufacturing the shipboard segment, longitudinal hatch coamings and shipboard standing poles are fixed on the shipboard segment by welding respectively. Particularly, before the erecting welding, the longitudinal hatch coamings are reserved with inverse deformation, and the inverse deformation value is 0 to 10mm deviation of the end parts of the longitudinal hatch coamings relative to the vertical wall plane of the inner shell. Therefore, in the method, the longitudinal hatch coamings and the shipboard standing poles are mounted at the stage of manufacturing the shipboard segment, and the method for controlling the mounting accuracy is also provided. Compared with the prior shipbuilding method, the method has the advantages of improving the segmentation integrity, saving the assembling and welding time of the longitudinal hatch coamings and the shipboard standing poles at the building berth (dock) stage and simultaneously saving polishing and painting time.

Description

technical field [0001] The invention relates to the field of shipbuilding engineering, and more specifically relates to a method for integrally building side sections, longitudinal hatch coamings and side standing columns during shipbuilding. Background technique [0002] The traditional method in the installation stage of the longitudinal hatch coamings and side posts of container ships is to carry out bulk installation at the berth (dock). Shipyards of the prior art all adopt this construction method. like Figure 4 As shown, the side section is not equipped with hatch coamings and side posts during the fabrication stage of the section. [0003] The problem is that the shipbuilding method of the prior art requires a lot of time and labor for the assembly and welding of hatch coamings and side posts at the berth (dock) stage, and it will also consume a lot of time in the grinding and painting stages. manpower and time costs. Contents of the invention [0004] In view o...
