Groove sealing plate and unloading plate joint structure of welding type groove-shaped bulkhead

Abstract

The invention discloses a groove sealing plate and unloading plate joint structure of a welding type groove-shaped bulkhead. The structure comprises a groove strip panel, a groove strip web plate, groove sealing plates and an unloading plate, the groove strip panel is welded with the groove strip web plate, the groove sealing plates are connected to the groove strip panel, and the unloading plateis simultaneously connected to the groove strip web plate and the groove sealing plate; the two sides of the groove strip panel are connected with the groove sealing plates, the two groove sealing plates are each connected with a knee plate, the two knee plates are connected to the two sides of the groove strip panel respectively, and the free edges of the knee plates are in a circular arc shape;the groove strip panel, the two groove sealing plates and the two knee plates are integrally formed; and an inclined plate with an unloading function is fixedly arranged on the rear end surface of each knee plate, and the inclined plates are simultaneously connected to the groove strip web plate and the unloading plate. The stress at the corner point can be greatly reduced, the welding seams are reduced, the construction difficulty is greatly reduced, the construction is convenient, and the welding quality is favorably controlled.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a joint structure of a groove sealing plate and a cargo unloading plate of a welded groove bulkhead. Background technique [0002] The corrugated bulkhead is a bulkhead used to divide the cargo hold of the hull. Because it does not use a flat plate as a bulkhead, but uses a corrugated plate as a bulkhead, it is named a corrugated bulkhead. According to the different processing technology, the grooved bulkhead can be divided into two types: bending type and welding type. In the structure of welded corrugated bulkhead, the corrugated face plate and corrugated web are connected by welding. [0003] The unloading board, as the name suggests, is a board that is designed to prevent cargo from piling up. Such as figure 1 As shown, due to the existence of grooves in the corrugated bulkhead, an area enclosed by the corrugated face plate 101, the corrugated web 102 and the bottom plate is...

AI Technical Summary

Problems solved by technology

The disadvantages of this structure are: troublesome construction, more welding, and the welding quality of the stress concentration point is not easy to be guaranteed

[0005] In another existing design, the problem of high stress at the corners is solved by adding two plates. However, due to the addition of two plates, the number of welds at the corners has also increased from the original 4 to 6. Therefore, the construction is more troublesome

In addition, due to the increase of parts and welds, the welding quality is not easy to be guaranteed
