DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for assembling a hull block by assembling a plurality of longitudinal members, transformer members and the like on a skin plate such as an outer plate, a deck and a bulkhead of a hull.

[0002]

2. Description of the Related Art Generally, when building a hull, a hull block is constructed by dividing an outer plate, a deck, a bulkhead and the like of the hull in advance, and the hull blocks are assembled to construct a hull.

Conventionally, when building a hull block having a flat portion, as shown in FIG. 6, a plurality of longitudinal members 2 are welded to a skin plate 1 to form a panel block 3. A method of assembling the hull block by assembling the transformer member 4 and, as shown in FIG. 7, assembling the longitudinal member 2 on the plurality of transformer members 4 in advance to form the framing block 5, and attaching the framing block 5 to the skin plate 1 To build a hull block.

[0004]

By the way, when the panel member 3 is formed by welding the longitudinal member 2 to the skin plate 1, as shown in FIG. 8, the longitudinal member 2 has an upright angle due to mounting errors and welding distortion. Accuracy may be degraded.

Therefore, in the conventional method shown in FIG.
A large notch 7 is formed in the slot 6 of the transformer member 4, and when the transformer member 4 is assembled to the panel block 3, the transformer member 4 is suspended from above as shown in the drawing to assemble the panel block 3. .

However, since the slot 6 has a large notch 7 as shown in FIG. 9, the notch 7 must be closed with a color plate 8.
Installation work and contact work had to be performed manually.

In the conventional method shown in FIG. 7, a slit-type slot 9 as shown in FIG. 10 is formed in the transformer member 4 and the long member 2 is inserted through the slot 9 to form the frame block 5. Is formed, it is not necessary to form the panel block 3, and the color plate 8 can be omitted.

However, when the frame block 5 is formed, the long members 2 are manually inserted into the slots 9 one by one, and there is a problem that the operation takes a long time.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a method of constructing a hull block in which a long of a panel block can be simultaneously inserted into a slot of a transformer member. It is in.

[0010]

According to the present invention, a panel block is formed by welding a long member to a skin plate, and a plurality of transformer members are assembled to the panel block. In the construction method, the longitudinal member is cut diagonally in the vertical direction,
The lower part of the tip of the cut long member becomes convex
And arranged in parallel on the skin plate
A panel block is formed in contact with the transformer member . The transformer member is held upright at a predetermined interval in parallel with the panel member.
Insert into the lot to correct the mounting angle
While moving the panel block,
This is a method for building a hull block in which the transformer member is assembled to a lock .

[0011]

According to the above construction, the longitudinal member is vertically moved in advance.
Diagonally in the direction
A plurality of scans are arranged in parallel so that the lower part of the tip is convex.
Since the panel block is formed by welding to the mounting plate, even if there is an error in the upright angle accuracy of each longitudinal member, each longitudinal member can be inserted into each slot of the transformer member from the distal end.

Also, since the slot is inserted into the slot from the downwardly projecting tip, the upright angle of the longitudinal member is corrected by the slot, and the longitudinal member can be easily inserted into the slot.

Next, the method of the present invention will be described with reference to the above equipment examples.

In carrying out the present method, a plurality of transformer members 4 (shown in FIG. 5) having slit-type slots 9 through which the long members 2 are inserted are manufactured in advance.
Cut the longitudinal member before processing into a predetermined length diagonally in the vertical direction.
Then, the cut long member 2 is placed under the tip 2a.
So that it becomes convex and the upper part of the rear end 2b becomes convex.
A plurality of panels are arranged in parallel and welded to skin plate 1
Block 3 (shown in FIG. 1) is manufactured.

On the other hand, the transformer holding equipment 10 moves each gripping and positioning device 11 in the front-rear direction (X direction in FIG. 1) so as to be positioned at a predetermined interval, and arranges the gripping and positioning devices 11 on both sides so as to face each other. .

Next, the transformer member 4 is placed on each of the gripping positioning devices 11 (FIG. 2), and
The positioning in the width direction (Y direction in FIG. 1) is performed by the positioning adjustment device 18 and the positioning adjustment device 18, and the transformer member 4 is gripped and fixed by the clamp 19 of the clamp support device 20 (FIG. 3).

Next, after disposing the panel block 3 on the surface plate 32 and positioning the panel block 3 with the guide device 35 , the draw chain 33 is driven to move the panel block 3 toward the transformer holding facility 10, The front end 2a of the long member 2 is inserted into the slot 9 of the upright transformer member 4, and the panel block 3 is moved while being guided by the panel guide 27, and the long member is inserted into the slot 9 of the upright transformer member 4. 2 and the transformer member 4 is assembled to the panel block 3.

At this time, the width direction positioning device 17 and the positioning adjusting device 18 are lowered or moved so as not to hinder the movement of the panel block 3 (FIG. 4).

When the long member 2 is inserted into the slot 9, the distal end 2 a of the long member 2 that projects downward is inserted into the slot 9.
So that even if there is an error in the upright angle of each longe member 2, it can be easily inserted, and since it is inserted from the lower end 2a, the upright angle of the longe member 2 is corrected to an appropriate angle by the slot 9. As a result, insertion into the slot 9 becomes easy.

Thus, each of the long members 2 of the panel block 3 can be inserted into the slot 9 at the same time, and the work can be performed in a short time. In addition, Longi
The material 2 is formed such that the lower part of the front end 2a is convex and the rear end 2
b is arranged in parallel so that the top of
That panel block 3 was formed by welding to rate 1.
Therefore, when connecting the panel block 3 in the vertical direction,
In addition, welding of the front end portion 2a and the rear end portion 2b of the long member 2 is performed.
It will be easier.

The movement of the panel block 3 and the positioning of the transformer member 4 are automatically performed by an automatic controller (not shown).

Further, since the slit member 9 is provided in the transformer member 4, there is no need to attach a color plate.

[0034]

In summary, according to the present invention, since the front end of the long member is notched in advance so as to be convex downward, there is an error in the upright angle of each long member of the panel block. However, it can be inserted into the slot of the transformer member from the tip.

Thus, since the long members of the panel block can be simultaneously inserted into the slots, the operation can be performed in a short time.
