A normal construction method for the outer plate of a ship's bow section

A construction method and ship technology, applied in ship construction, hull bow, hull parts, etc., can solve problems such as affecting production efficiency, aggravating the labor intensity of construction personnel, and changing the main dimensions of the subsections, so as to improve construction efficiency and construction accuracy. Avoid the effect of insufficient dimensional accuracy of the outer plate, and avoid the change of the outer plate line shape and the effect of

Problems solved by technology

[0002] At present, the construction method of the bow section of the ship is: the inner bottom is used as the base surface, and after the longitudinals of the outer bottom are positioned, the outer plate is reversed, and then turned over as a whole, and the internal structure is welded. This construction process requires a crane to cooperate with a hoisting horse. Segmental turning, although it avoids the overhead welding operation, it requires construction personnel to perform segmental turning, which increases the labor intensity of the construction workers, and welding after segmental turning is very easy to produce deformation, resulting in changes in the main dimensions of the segment, which cannot meet the requirements Accuracy tolerance requirements require rework, which greatly affects production efficiency

Abstract

The present invention provides a normal construction method for the outer plate of a bow section of a ship, including: S1, making a side view and a cross-sectional view of the outer plate of the bow section and the frame line on the main hull; S2, obtaining a transverse section of the tire frame ; S3, obtain the cross-sectional view of each rib frame formwork; S4, process each rib frame formwork; S5, obtain the on-site operation plan of the frame frame; S6, process the column; S7, process the outer plate; S8, process the processed rib The tire frame formwork and the corresponding column are installed in small groups to obtain a rib formwork frame, and each obtained rib formwork frame is hoisted on the ground of the tire frame; S9, hoisting the outer plate; the present invention is based on the curve of each rib profile on the outer plate. The shape of the tire frame formwork ensures that the working surface of each tire frame formwork is closely attached to the outer surface of the outer plate, and the support stability during operation is ensured; in addition, the present invention adopts the normal construction mode to avoid the turning over of the traditional reverse construction mode work, improve construction efficiency and construction quality.

Description

technical field [0001] The invention belongs to the technical field of ship construction, and in particular relates to a normal construction method for the outer plate of a bow section of a ship. Background technique [0002] At present, the construction method of the bow section of the ship is as follows: the inner bottom is used as the base surface, and after the longitudinal frame of the outer bottom is positioned, the outer plate is reversely attached, and then the whole is turned over and the internal structure is welded. This construction process requires a crane to cooperate with a crane. Although it avoids the overhead welding operation, it requires the construction personnel to turn over in sections, which increases the labor intensity of the construction personnel, and the welding after the section is turned over is easy to produce deformation, resulting in changes in the main dimensions of the sections, which cannot meet the Precision tolerance requirements, which...
