Bilge keel structure and construction method thereof

Abstract

The invention relates to the technical field of ship building, and discloses a bilge keel structure and a construction method thereof.The bilge keel structure comprises an upper web, a lower web, an upper base plate, a lower base plate and a round pipe which are arranged in the length direction of a ship, the inner side of the upper web is smoothly connected with a hull outer plate through the upper base plate, and the inner side of the lower web is smoothly connected with the hull outer plate through the lower base plate; the outer side of the upper web plate is fixedly connected with the outer side of the lower web plate through a round pipe, the upper web plate, the lower web plate and the hull outer plates jointly form a triangular structure, the bilge keel structure comprises a first section, an inlaying section and a second section which are sequentially connected, and the inlaying section stretches across the connecting positions of the adjacent hull outer plates. The advantages of the bilge keel structure during segmented installation are reserved, and welding construction of the bilge keel structure is not affected.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a bilge keel structure and a construction method thereof. Background technique [0002] The bilge keel is a longitudinal structure arranged in the round area of ​​the ship's bilge along the length of the ship. The purpose is to increase the damping of the ship's roll, reduce the degree of roll, and improve the stability and seaworthiness of the ship. [0003] When constructing the bilge keel, the bilge keel structure is generally divided into several sections along the length of the ship according to the length of the section. When the berth is closed, the bilge keel is closed and docked with the segments. However, since the bilge keel is attached to the outer plate of the bilge part of the hull, when the outer plate of the hull is closed, it will hinder the welding and closing ring seam of the outer plate near the bilge keel. When the section enters the berth closing stag...

AI Technical Summary

Problems solved by technology

However, since the bilge keel is attached to the outer plate of the bilge part of the hull, when the outer plate of the hull is closed, it will hinder the welding and closing ring seam of the outer plate near the bilge keel. When the section enters the berth closing stage, the closing fractures of adjacent sub-sections of the bilge keel are often difficult to align, and there is a certain gap difference, which affects the closing and installation of the bilge keel
