Description

Technical fields:

[0001] This invention relates to the field of welded structures, and in particular to a corner hole joint structure that eliminates the need for opening corners. Background technology:

[0002] In conventional ships, corner joints between elbow plates and platform plates or horizontal girder stiffeners (T-sections) require R50 corner holes, using fillet welds. With the increasing number of polar research vessels and transport ships operating in the extreme low-temperature environment of the polar regions, regulations impose high requirements on the hull structure's resistance to low temperatures. Specifically, the Russian Classification Society (RCS) regulations impose strict restrictions on structural openings on outer plating in ice-covered areas, and the conventional elbow plate joint design cannot meet the regulatory requirements that prohibit corner holes on outer plating in certain ice-covered regions.

[0003] To meet the requirements of welding corner hole nodes for polar vessels and reduce the impact of low positions on the welded parts, there is an urgent need for a corner hole node structure that does not require opening corners. This would help solve the technical problem of the lack of a welding corner hole node structure that can adapt to low-temperature environments in the existing technology. Summary of the Invention:

[0004] In one embodiment, the present invention provides a corner hole node structure that does not require opening corners. By inserting protruding sections into predetermined gaps for welding, the overall strength is improved, and the strength and stress requirements of low-temperature environments are met. This helps to solve the technical problem of the lack of a welded corner hole node structure that can adapt to low-temperature environments in the prior art.

[0005] The corner hole node structure without opening corners includes an outer plate, a platform plate, and an elbow plate;

[0006] The outer panel is located on one side and is vertically oriented;

[0007] One end of the platform plate is connected to the outer plate, and the other end of the platform plate extends outward from the outer plate. A predetermined gap is left at the end of the platform plate near the outer plate.

[0008] The elbow plate is located at the angle between the outer plate and the platform plate, and a protruding section is provided at the contact position with the predetermined interval gap. The protruding section is inserted into the predetermined interval gap and welded to the platform plate.

[0009] In one embodiment, the platform plate is a T-shaped profile, the web of the T-shaped profile is welded to the protruding section, and the predetermined interval gap is provided at the position of the wing plate of the T-shaped profile near the outer plate.

[0010] In one embodiment, the length of the predetermined interval gap is 50 millimeters.

[0011] In one embodiment, the welding employs CO2 butt welding to create a bevel or full penetration fillet welding to create a bevel.

[0012] In one embodiment, a ceramic gasket is provided at the other end of the weld.

[0013] In one embodiment, the height of the protruding section is equal to the thickness of the wing plate.

[0014] In one embodiment, a vertically arranged profile structure is provided below the elbow plate.

[0015] In one embodiment, the web plate is chamfered at the position where it connects to the protruding section.

[0016] In one embodiment, the chamfer angle is 15 degrees, and the wing plate with the chamfer near the end of the protruding section has a reserved width of 15 millimeters.

[0017] In one embodiment, the remaining contact portion between the wing plate and the elbow plate is formed by fillet weld. Attached image description:

Well-known and / or repeated functions and structures are not described in detail to ascertain the true intent based on the user's historical operations, and to avoid unnecessary or redundant details that would obscure this application.

[0046] Currently, to address this issue, production design typically involves making the ends of the T-profiles into a larger shape to replace the elbow plate structure. While this avoids the need for openings, it doesn't align with the detailed design and creates discrepancies. Making the T-profile ends irregular reduces material utilization, and the curved ends of the panels require machining, increasing on-site processing workload. Furthermore, the panels, outer panels, and frame materials can easily create narrow spaces, hindering on-site construction.

[0067] 1. According to the nodes of this invention, the structural form is consistent with the detailed design, with no significant differences, and it meets the specification requirement that corner holes cannot be opened on the outer plate of certain ice-covered areas.

[0068] 2. Compared with the current structural form of making the ends of T-profiles into a large-head shape to replace the elbow plate, the web of the T-profile is regular, which improves the material utilization rate.

[0069] 3. Compared with the current structure that uses large ends to replace elbow plates, the panel does not have a linear shape and does not require processing, thus reducing the amount of on-site processing work.

[0070] 4. Compared with the current structural form that uses large ends to replace elbow plates, the panel area is reduced and the space between the panel and the outer panel and the frame is increased, which is beneficial for on-site construction.
