Problems solved by technology

[0003] In the prior art, the following two forms are often used for welding between two adjacent bilge keel backing plates: the first is to weld the two backing plates to the outer plate first, and then use CO 2 Gas shielded welding directly welds the gap between the two backing plates. This method will easily form a molten pool on the outer plate during the welding process, which will cause certain damage to the outer plate. In the subsequent use process, the keel will be stressed. Finally, the outer plate is torn through the backing plate, and the outer plate is easily torn at the molten pool, resulting in a decrease in the service life of the outer plate. In addition, the temperature field during the welding process will

Abstract

The invention relates to the technical field of shipbuilding, and discloses a hull bilge keel base plate mounting method. The ship bilge keel base plate mounting method comprises the steps of fixing built-in base plates to segmented outer plates at intervals in the length direction of a hull, and assembling the segmented outer plates into a ship outer plate; fixing glass fiber cloth between the two ends of the built-in base plate and the ship outer plate in the length direction of the hull; fixing an embedded base plate between the two built-in base plates, and forming a butt joint seam by theembedded base plate and the two built-in base plates, wherein the glass fiber cloth is located between the butt joint seam and the ship outer plate; and welding the butt joint seam so as to enable the built-in base plate and the embedded base plate to be connected. According to the hull bilge keel base plate mounting method, the base plate connection reliability is high, and the ship outer plateis not prone to damage.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for installing a hull bilge keel backing plate. Background technique [0002] The bilge keel of the ship is a structure installed on the outer plate of the bilge in the middle area of ​​the ship. It is mainly used to increase the damping when the ship rolls, thereby increasing the seakeeping and stability of the ship and greatly reducing the roll of the ship. The bilge keel usually consists of a backing directly connected to the shell plating and a keel connected to the backing. The outer plate of a large ship needs to be assembled and welded by multiple plates. Therefore, along the length of the ship, the backing plate of the bilge keel is often welded to the outer plate with multiple backing plates respectively, and the gap between two adjacent backing plates is Solder connection. [0003] In the prior art, the following two forms are often used for welding betw...
