A method of constructing a hull block by assembling transformer members 4, and as shown in FIG. There is a method of assembling to construct a hull block.

0004

[Problems to be Solved by the Invention] By the way, when the longitudinal member 2 is welded to the skin plate 1 to form the panel block 3, as shown in FIG. The accuracy may deteriorate.

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

However, as shown in FIG. 9, the slot 6 has a large notch 7, so this notch 7 must be covered with a collar plate 8.
Installation work and connection work had to be done manually.

Furthermore, in the conventional method shown in FIG. 7, a slit-shaped slot 9 as shown in FIG. Therefore, there is no need to form the panel block 3, and the color plate 8 can be omitted.

[0008] However, when forming the framework block 5, the longitudinal members 2 are manually inserted one by one into the slots 9, which poses a problem in that the work takes a lot of time.

The present invention was devised to solve the above-mentioned problems, and its purpose is to provide a method for constructing a hull block that allows longitudinals of a panel block to be simultaneously inserted into slots of a transformer member. It is in.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a hull block in which a longitudinal member is welded to a skin plate to form a panel block, and a plurality of transformer members are assembled to the panel block. In the construction method, the transformer members are held upright in parallel with a predetermined interval apart, and the tips of each of the longitudinal members are cut out diagonally so that the lower part thereof is convex, and the slots of the transformer members are cut out. In this method, the tip of each longitudinal member is inserted to correct the mounting angle of the longitudinal member, and then the panel block is moved and the transformer member is assembled on the panel block.

[0011]

[Operation] According to the above structure, since the tip of the longitudinal member is cut out diagonally so that the lower part is convex,
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 its tip.

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