A method for conformal construction of a full-width type structure section of a naval ship

Abstract

The invention discloses a conformal construction method of a full-width type structure section of a warship, which mainly comprises the inverse construction of a left section and a right section. A left section and a right section are normally lif to a section bracket, and are combined on that section bracket to form a full-width structure section; Fix sectional inner wall panels, sectional outfitting and L-shaped stiffener panels; The steps of hoisting the section bracket with full-width structural segments to the final assembly area. The present invention is a section which can only be constructed in reverse state before, a scheme which can be constructed normally is provided, but also provides a full-width construction option for segments previously constructed only in half-width form,The method also changes the transportation form of the full-width structure segments which can only be transported in reverse state, so that the sections can be transported in a normal state, the structural deformation produced in the process of lifting, turning over, shelving, painting and the like of the sections is avoided, the construction scale of the sections is enlarged, and the pre-outfitting rate of the sectionss is improved.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a segmental conformal construction method of a full-width structure of a ship. Background technique [0002] Due to the characteristics of many cabins and thin and easy-to-deform panel frames, the full-width cabin section of the ship is prone to structural deformation during the process of lifting, shelving, and painting, mainly manifested in the following three points: [0003] First, the segmented panel frame is relatively light and thin as a whole. During the lifting process, since the stress points are concentrated at the local lifting points, it is easy to deform due to uneven force. [0004] Second, the section with more cabins has fewer strong support points. If it is left on the mast for a long time, the section structure is easily deformed due to the influence of gravity. [0005] Third, because the lower end of the section with many cabins is basically a light an...

Problems solved by technology

[0003] First, the segmented panel frame is lighter and thinner overall. During the lifting process, since the stress points are concentrated at the local lifting points, it is easy to deform due to uneven force

[0004] Second, the section with more cabins has fewer strong support points. If it is left on the mast for a long time, the section structure is easily deformed due to the influence of gravity.

[0005] Third, because the lower end of the section with many cabins is basically a light and thin bulkhead, in order to protect the bulkhead from deformation, it is usually placed on the deck at the upper end as the base surface, so the impact force of sandblasting and spraying during spraying The weight of sand is easy to affect the segmental deformation

At the same time, weak structures such as inner walls, doors and windows, and other outfitting parts that require high structural deformation will be required to be installed in the final assembly stage, which will have a certain impact on the integrity of the structure and the efficiency of construction.
