Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying exemplary drawings.

1 to 4, the curved block to which the present invention is applied is formed by providing a curved plate member 10 on a work surface plate 21 and then pressing a curved plate member 10 against the curved plate member 10, (14) and the partition member (16) through the through-hole (12).

That is, as shown in Fig. 1, the curved block is formed by a process of setting a curved plate member (a), a process of mounting a color plate (b), a process of assembling a curved stiffener (c) (D), respectively.

First, in the step (a) of setting the curved plate member, the curved plate member 10 is a member that forms the outer wall of the hull, and particularly, a side shell or the like which forms a curved outer wall portion of the outer wall of the hull .

The step (A) of setting the curved plate member may be performed by using a ship modeling program (TRIBON) to fabricate an outer wall shape of an accurate shape, and to accurately express the curvature along the linear shape of the ship, The bottom surface of the curved plate member 10 is more stably supported by the pin jig 23 by raising the curved plate member 10 by using the pin jig 23 provided in the upright direction with respect to the curved plate member 10. At this time, the curved plate member 10 is precisely positioned at a predetermined position of the jig drawing, and is manufactured by attaching an iron plate and an iron plate by the welding technique (WPS) shown in the assembly drawing.

That is, in the step (A) of setting the curved plate member, the height is adjusted in accordance with the curvature of the curved plate member 10 in a state where the plurality of pin jigs 23 are erected on the working surface plate 21 And then installing the curved plate member 10 in a horizontal direction by using a plurality of pin jigs 23 on the work surface plate 21. [

The color plate 12 is coupled to the curved plate member 10 so that the angle of installation of the curved stiffener 14 with respect to the curved plate member 10 And serves to finish the slot 16a formed in the partition member 16, and corresponds to a kind of reinforcement finishing material.

Here, the step (B) for constructing the color plate is also performed by using the modeling program of the ship to fabricate the color plates 12 having an exact shape corresponding to the curvature of the curved plate member 10, (12) to the curved plate member (10). The collar plate 12 is fabricated so that the bottom surface of the curved plate member 10 has a curvature corresponding to each curved portion of the curved plate member 10 and then the collar plate 12 is inserted into the curved plate member 10, To the right side of the frame.

In addition, in the assembling step (C) of the curved stiffener, the curved stiffener (14) is provided with a plurality of main portions (14) which are coupled in a direction perpendicular to the curved plate member As a reinforcing member, it corresponds to a constituent element for securing the structural rigidity of the hull. In particular, when the curved stiffener 14 is installed on the curved plate member 10, it is possible to easily mount the curved stiffener 14 on the collar plate 12 at an accurate assembly position without using a tool such as a protractor .

At this time, the curved stiffener 14 is formed into an accurate shape corresponding to the curvature of the curved plate member 10 by using a ship modeling program. That is, the curved stiffener 14 is formed by bending and twisting over the entire length of the material so as to conform to the curvature of the curved plate member 10 through the cold working and the hot working, respectively So that the fabrication is performed.

The step of assembling the curved stiffener 14 may be performed in a step of assembling the curved stiffener 14 to the curved plate member 10 by setting the assembly reference through the contact with the color plate 12, And in place with respect to the plate member (10). Also in this case, it is preferable that the curved stiffener 14 is attached to the curved plate member 10 at a predetermined position by utilizing one side of the collar plate 12 as an assembly reference plane.

In the assembling step (D) of the partition member, the partition member 16 is a member forming a structural partition of the hull. The partition wall member 16 is a member which forms a structural barrier in a direction perpendicular to the curved plate member 10 and the curved stiffener 14 Which is a component that plays a role of dividing the internal space of the hull into a plurality of parts. Particularly, the partition member 16 has a slot 16a formed in the bottom surface thereof in a long-cut shape for engagement with the curved stiffener 14. [

At this time, the partition member 16 is fabricated in a precise shape conforming to the curvature of the curved plate member 10 for coupling the curved plate member 10 and the curved reinforcing member 14 using a ship modeling program .

The step of assembling the partition member 16 may be performed by using the color plate 12 while moving the manufactured partition member 16 to a predetermined position with respect to the curved plate member 10 and the curved stiffener member 14 Lt; / RTI > In this case, the partition wall member 16 is formed to have a flat surface with respect to the curved plate member 10 and the curved stiffener member 14 by utilizing one side surface of the color plate 12 and the side surface of the curved stiffener 14, It is preferable to be installed by being joined to the position.

When the curved stiffener 14 and the partition wall member 16 are installed on the curved plate member 10 through the above-described process, the collar plate 12 is inserted into the curved plate member 10, And the slot 16a formed in the partition wall member 16 are joined to each other so as to close the opening portion of the slot 16a.

Therefore, when the curved block is manufactured through the drying process, the color plate 12 is installed on the curved plate 10 in the preceding process, and the curved stiffener 14 is installed therebetween And then the partition member 16 can be lowered and assembled with respect to the curved plate member 10 and the curved stiffener 14.

As a result, in the process of manufacturing the curved block according to the present invention, various types of tools are installed to determine the installation angle and installation position in the course of setting the curved stiffener 14 to the curved plate member 10 It is possible to greatly shorten the working time required for manufacturing the curved block. In particular, since the work process for removing various kinds of tools after the installation of the curved stiffener 14 is not necessary, the productivity of work resulting from the reduction of the process can be further improved.

The present invention is characterized in that the shape of the color plate 12 for determining the installation angle and installation position of the curved stiffener 14 relative to the curved plate member 10 is determined by the curved plate member 10, (14), it is possible to expect an excellent effect in maintaining the degree between the two.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limited to the particular details of the embodiments set forth herein. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
