Description

Composite hull structure

Technical Field

The utility model relates to the field of ship manufacturing, in particular to a composite hull structure.

Background

In the manufacture of ships, particularly in the manufacture of high-speed yachts, in order to pursue high-speed traveling, it is necessary to design excellent linearity of a hull, ensure smoothness of the hull, and consider the power output of the ship, and also to consider the weight reduction of the ship itself. In addition, since the yacht is not a quick-burn product, it is necessary to achieve both strength and reliability of the yacht while pursuing a speed.

At present, the materials used as the hull mainly comprise glass steel, steel or aluminum, and the hull made of glass steel can ensure lighter overall weight, but has relatively lower strength and environmental protection; the steel hull can ensure higher strength and durability, but has larger weight and high maintenance cost; the weight and strength of the aluminum hull are between those of the glass steel hull and the steel hull, but the aluminum raw materials are expensive, so that the cost is high, the processing difficulty is high, and the impact and abrasion resistance is poor.

Therefore, the hull made of any material has obvious defects, and the weight, the strength and the durability cannot be fully considered. Therefore, improvements to existing composite hull structures are needed to address the problem that existing composite hull structures cannot be compatible with both weight and strength.

Disclosure of Invention

The utility model aims to provide a composite hull structure, wherein a main hull adopts a steel plate structure so as to ensure the strength of the hull, and an upper building adopts an aluminum alloy structure so as to reduce the weight of the hull, thereby solving the problems of the weight and the strength of the hull.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the composite hull structure comprises a main hull and an superstructure arranged on the main hull, wherein the main hull is a steel structure, the superstructure is an aluminum alloy structure, and the steel structure is fixedly connected with the aluminum alloy structure;

correspondingly, the steel structural body and the aluminum alloy structural body are riveted through rivets; the steel structure body and the aluminum alloy structure body are connected in a riveting mode, so that the strength and the weight of the ship body are simultaneously considered;

correspondingly, the steel structure body and the aluminum alloy structure body are welded through an aluminum-titanium steel plate; the aluminum-titanium steel plates are connected in a transitional manner, so that the problems of complex riveting process, low production efficiency and poor water tightness can be solved, the electrolytic corrosion phenomenon of the riveting position is avoided, and the problem of further reduction in structural strength caused by corrosion of materials is solved;

correspondingly, the aluminum-titanium steel plate comprises an aluminum plate layer, a steel plate layer and a titanium plate layer positioned between the aluminum plate layer and the steel plate layer, wherein the aluminum plate layer is used for being welded with the aluminum alloy structural body, and the steel plate layer is used for being welded with the steel structural body;

correspondingly, the thickness of the aluminum-titanium steel plate is 10-24mm, and the width is 10-25mm.

The beneficial effects of the utility model are as follows:

on one hand, the main hull adopts a steel plate structure to ensure the strength of the hull, and the superstructure adopts an aluminum alloy structure to lighten the weight of the hull, so that the weight and the strength of the hull are both considered;

on the other hand, the aluminum titanium steel plate is used as the transition connecting plate of the steel structure body and the aluminum alloy structure body, so that the problems of complex process, low production efficiency, poor water tightness, corrosion and the like which exist in the situation that the steel structure body and the aluminum alloy structure body cannot be directly welded and can only be riveted are solved, the conventional welding mode can be directly adopted for construction, the production efficiency is improved, the structural strength of the connecting part of the steel structure body and the aluminum alloy structure body is enhanced, the water tightness of the connection is ensured, the electric corrosion reaction between materials is reduced, and the structural life is prolonged.
