DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a double hull block for constructing a hull block having a double hull structure.

[0002]

2. Description of the Related Art Some ships, such as a double bottom structure, have a hull structure formed in a double hull.

Generally, when such a hull is constructed,
The hull is constructed by constructing previously split double hull blocks and assembling those double hull blocks.

Conventionally, when a double hull block having a flat portion is constructed, as shown in FIG.
The upper and lower panel blocks 3 and 4 are formed by welding the vertical bone members 2 such as the longitudinals, and the horizontal bone members 7 such as transformers having the slots 5 and 6 formed vertically as shown in FIG. After the vertical bone member 2 of the upper panel block 3 is inserted into the slot 5 above the horizontal bone member 7 and the horizontal bone member 7 is welded to form a hull block 8, the hull block 8 is then formed. And the vertical hull member 2 of the lower panel block 4 is inserted into the slot 6 below the horizontal skeleton member 7 of the hull block 8 and then welded to construct a double hull block.

[0005]

However, in the above-mentioned conventional method, the slots 5 and 6 of the lateral bone member 7 are not shown in FIG.
As shown in FIG. 4, a notch 9 through which the vertical bone member 2 is inserted is formed. When assembling the hull block 8, the vertical bone member 2 is inserted into the slot 5 while lowering the horizontal bone member 7 from above. In addition, when assembling the double hull block 11, the vertical bone member 2 can be inserted into the slot 6 while lowering the inverted hull block 8 from above as shown in FIG.

However, after the vertical bone members 2 are inserted into the slots 5 and 6, the notches 9 of the slots 5 and 6 need to be closed by the color plate 10, as shown in FIG. There is a problem that an automatic welding machine cannot be used for welding No. 10.

In the conventional method, since the vertical bone members 2, the horizontal bone members 7 and the like are assembled on the large skin plate 1 to form the panel blocks 3, 4 and the hull block 8, the assembly of the bone members 3, 4 is performed. It was difficult to automate various processes such as welding straightening.

Accordingly, the present invention has been made to solve the problems of the above-mentioned conventional method, and its object is to automate various processes in building a block and to automate welding of a bone member. It is an object of the present invention to provide a method of building a double hull block.

[0009]

In order to achieve the above object, the present invention comprises two panel blocks formed by welding a vertical bone member to a skin plate, and a horizontal bone member having upper and lower slots. Inserting the vertical bone member of the one panel block into the slot of the horizontal bone member and welding the horizontal bone member to form a hull block, inverting the hull block, and inserting the hull block into the other slot of the horizontal bone member. In the method for constructing a double hull block in which the vertical bone member of the other panel block is inserted and welded, the panel block is formed by a plurality of modules obtained by dividing the skin plate, and a groove is formed on the outer periphery of these modules. Thereafter, these modules are welded and joined to form upper and lower panel blocks. After forming the block, the Harrub
Invert the lock and set the reference position with the positioning device.
Fix and support the panel block with a vertical bone positioning device
While making fine adjustments in the horizontal direction,
Insert the material through the slot in the horizontal bone member of the hull block
Te is a construction method of a double hull blocks to assemble the panel blocks the lower to the hull block.

[0010]

According to the above-mentioned method, when joining a plurality of modules to form upper and lower panel blocks, the groove around the modules is machined, so that a panel block with good precision can be formed. Since the hull block is constructed by assembling the horizontal bone members on the block, the hull block can be constructed with high accuracy.

Further, by forming the panel block and the hull block with high accuracy, when assembling the lower panel block with the hull block, the panel block is horizontally moved to the slot of the transverse member of the inverted hull block. Since the vertical bone member can be inserted while being rotated, a slot without a color plate can be formed in the horizontal bone member, and the welding of the panel block and the hull block can be automated.

Further, since the panel block is formed by the divided modules, the steps of assembling and welding the module and correcting the distortion, and the assembling and welding of the panel block and the lateral bone member can be automated.
