Problems solved by technology

[0003] This method will cause a rather long period of installation and construction of the side door after the structural integrity of the side door area is completed, and two hoisting of the side door is required. In the dock stage, the hoisting resources are limited, and the follow-up construction is large. Constraints caused by the schedule and period of construction

Embodiment Construction

[0020] The present invention is further described below in conjunction with specific embodiment:

[0021] A segmented pre-installation method for ship side doors, characterized in that the method comprises the following steps:

[0022] Step 1. Segmentation. The installation of the side door needs to be carried out under the condition that the door frame and the surrounding structure are intact. Therefore, it is necessary to plan the structural scope involved in the pre-installation of the side door when dividing the sections. Because the side door It is a large outfitting piece with corresponding structural strength requirements, especially the structural reinforcement at the side door hinge eye plate. The segmented ports should be as far away from the side door hinge eye plate as possible to ensure the installation of the side door hinge eye plate precision.

[0023] Step 2. After the segmented structure is completed, the segmental structure of the side door is as follows: ...

Abstract

The invention relates to a segmented pre-installation method for a side door of a ship, which belongs to the technical field of ship building. The method includes the following steps: firstly divide into sections to ensure the integrity of the side door installation area; then carry out the hoisting of the side door, and locate and install the hinge eye plate according to the position of the side door; then, before hoisting, install the side door Temporarily strengthen and fix the closed state of the machine; finally carry out segmented loading welding, and carry out precision monitoring during the loading welding process. Through the segmental pre-installation method of the ship side door of the present invention, the outfitting integrity of the ship construction segment is improved, the number of ship construction and loading is reduced, the loading efficiency is improved, and the construction period is shortened; the side door is avoided twice in the loading stage. , It directly improves the resource utilization rate of the loading stage of the dock, reduces the construction amount of the loading stage, and further reflects the advanced progress of final assembly shipbuilding.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a segmented pre-installation method for ship side doors. Background technique [0002] With the development of the manufacturing industry, the professional-oriented organizational principle of shipbuilding is gradually replaced by the "ship intermediate product"-oriented construction strategy. Shipbuilding is no longer a single shipbuilding production entity that is bound by the "law of batches" and is traditionally oriented by various professions, but a production system oriented by the specialization of ship "intermediate products", consisting of dozens or even The production entity consists of hundreds of group production units. For ships with side doors, the original construction method is to hoist the side doors in place at the dock stage after the structural integrity of the side door area is completed, and then attach the side doors to the outer panels. After closin...
