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 ship side door section preassembling method, and belongs to the technical field of ship construction. The method comprises the following steps of firstly carrying out section division so as to ensure the integrity of a side door mounting area; then hoisting a side door, and positioning and mounting a hinge eye plate according to the position of the side door; then temporarily reinforcing and fixing a closed state of the side door before hoisting; and finally carrying out section final assembling welding, and carrying out precision monitoring in the final assembling welding process. According to the ship side door section preassembling method, the fitting-out integrity of the ship building sections is improved, the ship building final assembling number is reduced,the final assembling efficiency is improved, and the construction period is shortened; and two-time hoisting of the side door at the final assembling stage is avoided, the resource utilization rate in a dock assembling stage is directly improved, the construction amount of the assembling stage is reduced, and the advancement of ship final assembling is further embodied.

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...
