Problems solved by technology

However, the welding between the upper deck and the upper end of the corrugated bulkhead is completely overhead welding, and it is an overhead welding at a high position, which has defects such as inconvenient construction and poor safety, which is very unfavorable for the control of welding quality and construction safety, resulting in Poor forming, high cost, long cycle time

Embodiment

[0009] Example: A 16500DWT Class II product oil / chemical carrier, with longitudinal and transverse grooved bulkheads in the cargo hold. If according to the prior art scheme, after the grooved bulkhead and the lower deck are positioned, then the upper deck section is closed up, so there will be an overhead weld of more than 3000 meters. However, overhead welding is difficult in construction, poor in forming, inconvenient in construction, and long in cycle. Now the upper deck section is combined with the vertical and horizontal corrugated bulkhead section, that is, the middle longitudinal deck steel plate of the upper deck and the deck steel plate connected with the transverse corrugated bulkhead are separated from the upper deck section Connect part 2 for the deck. After the corrugated bulkhead 1 is formed, they are assembled and welded when the vertical and horizontal corrugated bulkheads are constructed in sections. At this time, the corrugated bulkheads carried out on the t...

Abstract

The invention provides a method for assembling a ship slot-shaped bulkhead, comprising the following steps of firstly manufacturing the slot-shaped bulkhead; subsequently erecting up the slot-shaped bulkhead; finally welding the slot-shaped bulkhead with a deck, wherein before the slot-shaped bulkhead 1 is erected up, an upper deck to be welded with the slot-shaped bulkhead is divided into a connecting part 2 to be welded with the slot-shaped bulkhead and a mainbody part 3; and furthermore, under the transversely horizontal state of the slot-shaped bulkhead, the connecting part of the deck is welded with the upper end of the slot-shaped bulkhead, the slot-shaped bulkhead welded with the connecting part of the deck is erected up and the mainbody part of the deck is spliced with the connecting part. Compared with the prior art, the safety in the welding process is greatly improved; the operation difficulty is greatly reduced; the welding efficiency and the welding quality are improved; the slot-shaped bulkhead can be well assembled and formed; material can be saved; the welding quality is improved; and the dock closure period can be shortened.

Description

technical field [0001] The invention relates to a method for installing a grooved bulkhead of a ship, which belongs to the technical field of ship manufacturing in transportation. Background technique [0002] Ship trough bulkhead is a bulkhead structure of ship cargo hold. Its form is that there are parallel longitudinal grooves on the bulkhead, so that the bulkhead obtained by using steel plates of the same thickness has a higher load-bearing capacity, so it is Large ships are used to save steel materials and improve the strength of the structure. Corrugated bulkheads have been widely used in the structural design of oil tankers and bulk carriers. In the design of the corrugated bulkhead of the cargo hold, how to rationalize the elements and forms of the corrugated corrugated bulkhead on the premise of satisfying the strength, stiffness and stability of the given ship according to the actual layout, external dimensions and functional requirements of the corrugated bulkhea...
