Stern part segment constructing method

Abstract

The invention discloses a stern part segment constructing method. In the stern part segmented constructing process, a ribbed plate, facing one side of a bow or stern, of the stern part serves as a platform base plane, remaining ribbed plates, a connecting plate and a platform plate are hung on the platform base plane to form a hull frame, and finally an outer plate is hung on the hull frame; in the ship stern part segment constructing process, the ribbed plate, facing one side of the bow or stern, of the stern part serves as the platform base plane, the remaining ribbed plates, the connectingplate and the platform plate are hung on the platform base plane to form the hull frame, the working face constructed by the stern part segment is changed into the plane from the original curved face,so that the stern part segment is more convenient to erect, erection of a complex curved face formwork jig frame is omitted, and stern part segment constructing time is saved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for building a stern section. Background technique [0002] In ship design, the line shape of the stern of some ships is designed as an asymmetric structure. The line shape of the stern section is relatively narrow, the left and right sides are asymmetrical, the two-way twist is large, and the change of the line shape is quite complicated. In the production process, the side-loading method with the outer panel as the bottom is usually adopted. In order to ensure the shape of the outer panel and the precision control of the segments, it is necessary to set up a formwork frame matching the shape of the outer panel on the ground to support the outer panel. The structure of the formwork frame is relatively complex and requires high precision. And because the outer plate is a curved surface structure, it is not convenient for marking and construction on the construction...

Problems solved by technology

In the production process, the side-loading method with the outer panel as the bottom is usually adopted. In order to ensure the shape of the outer panel and the precision control of the segments, it is necessary to set up a formwork frame matching the shape of the outer panel on the ground to support the outer panel. The structure of the formwork frame is relatively complex and requires high precision

And because the outer plate is a curved surface structure, it is not convenient for marking and construction on the construction site, and it is not easy to control the positioning and angle of the outer plate and the internal structure, so that the construction of the stern section requires higher technical requirements for the on-site construction personnel, and the production efficiency is low , it is easy to produce manufacturing precision errors, which makes the production cycle longer and cannot meet the production cycle control requirements of shipbuilding
