Description

Technical Field:

[0001] The present invention relates to the field of welded structures, and particularly to a corner hole node structure without corner opening. Background Art:

[0002] At the fillet joint of the conventional ship bracket and the panel of the platform plate or horizontal girder (T-section), a corner hole with a radius of 50 needs to be opened, and the node form of fillet welding is adopted. At present, more and more polar research ships and polar transport ships are being built and operating in the special low-temperature environment in the polar regions. The specifications have very high requirements for the low-temperature resistance of the hull structure. Among them, the Russian Maritime Register of Shipping (RS) specifications have strict restrictive requirements for the structural openings on the ice area outer plate. The node form of the conventional ship bracket cannot meet the specification requirements that the corner holes cannot be opened on the structures of some ice area outer plates.

[0003] In order to meet the requirements of the welded corner hole nodes of polar ships and reduce the influence of low temperature on the welded parts, there is an urgent need for a corner hole node structure without corner opening, which helps to solve the technical problem that there is a lack of a welded corner hole node structure that can adapt to the low-temperature environment in the prior art. Summary of the Invention:

[0004] In one embodiment, the present invention provides a corner hole node structure without corner opening. By inserting the protruding section into a predetermined interval gap for welding, the overall strength is improved, and the strength and stress requirements in the low-temperature environment are met, which helps to solve the technical problem that there is a lack of a welded corner hole node structure that can adapt to the low-temperature environment in the prior art.

[0038] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] The various solutions and features of the present application are described herein with reference to the accompanying drawings.

[0040] These and other features of the present application will become apparent from the following description of the preferred forms of the embodiments given as non - limiting examples with reference to the accompanying drawings.

[0041] It should also be understood that although the present application has been described with reference to some specific examples, those skilled in the art can surely implement many other equivalent forms of the present application, which have the features as described in the claims and thus are all within the protection scope defined hereby.

[0042] When combined with the accompanying drawings, the above - mentioned and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description.

[0043] Hereinafter, specific embodiments of the present application are described with reference to the accompanying drawings; however, it should be understood that the embodiments claimed are only examples of the present application and can be implemented in various ways. Well - known and / or repetitive functions and structures are not described in detail to determine the true intention according to the user's historical operations and to avoid unnecessary or redundant details from obscuring the present application. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but are merely used as a basis and representative basis for the claims to teach those skilled in the art to use the present application in substantially any suitable detailed structure in a variety of ways.

[0044] This specification may use phrases such as "in one embodiment", "in another embodiment", "in yet another embodiment", or "in other embodiments", which may each refer to one or more of the same or different embodiments according to the present application.

[0045] Currently, to solve this problem, in production design, the end of the T-shaped section is generally made into a large-head form to replace the structure of the bracket. Although this treatment can solve the problem of avoiding holes, it is inconsistent with the detailed design and there are differences. When the end of the T-shaped section is made into a large-head form, the shape becomes irregular, which will reduce the material utilization rate. The panel becomes curved at the end and needs to be processed, increasing the on-site processing workload. In addition, it is easy to form a narrow space between the panel and the outer plate and the stiffener, which is not conducive to on-site construction.
