Inclined double-bottom ship based on four-center alignment connection of inner bottom plate and side horizontal girder

Abstract

The invention discloses an inclined double-bottom ship based on four-center alignment connection of an inner bottom plate and a side horizontal girder. The inclined double-bottom ship comprises a side and a bottom part, wherein the side and the bottom part are of a double-layer structure, the two sides of the bottom part are of inclined structures, the middle part of the bottom part is of a straight structure, an inclined inner bottom plate (1) and the side horizontal girder (2) are made of a whole bending plate, flat plate structures at the two sides of the bending part of the bending plate are respectively used as the inclined inner bottom plate (1) and the side horizontal girder (2), the inclined inner bottom plate (1) and the side horizontal girder (2) are respectively connected with a side inner shell plate (4) and an inner bottom edge stringer (3) at the upper part and lower part of the bending part, and then centerlines of the four plates are crossed into a point. The inclined double-bottom ship has the advantages that the anti-fatigue strength is effectively improved, the structure weight is reduced, the workload of welding and grinding is reduced, the construction and processing technology is simplified, the working efficiency is improved, the cost is low, and the strength is high.

Description

technical field [0001] The present invention relates to a double-side skin ship with an inclined double bottom, more specifically, it relates to the improvement of the four structural connections of the inclined inner bottom plate, the side horizontal girder, the inclined inner bottom side girder, and the side inner shell plate . Background technique [0002] figure 1 Shows a cross-section of the centrosymmetric side of a prior art double skinned vessel with a sloping double bottom structure. figure 2 shown figure 1 The inclined inner bottom plate 1, the inner shell plate 4, the side horizontal girder 2 and the inclined inner bottom longitudinal girder 3 in the ship of the prior art shown in the prior art adopt a direct counter-welding structure. The fatigue strength of this structure is not enough. During the operation of the oil tanker, cracks are prone to appear at the connection between the inclined inner bottom plate of the cargo tank and the side horizontal girder,...

AI Technical Summary

Problems solved by technology

This structure is not strong enough in fatigue resistance. During the operation of the oil tanker, cracks are prone to appear at the connection between the inclined inner bottom plate of the cargo tank and the side horizontal girder, and there are also problems of welding and grinding difficulties in the production process.
