For example, the flexible material may be plastic, rubber, thin steel sheet, thin wood, thin wood plywood, reinforced plastic, etc., having elasticity, but is not limited thereto and may be made of any material capable of elastic restoration.

The lower bar 200 may be a long rod or a cylindrical member formed of a rigid material and extending in parallel with the upper bar 100. In the present specification, a rigid material refers to a material which is relatively unmodified by an external force relative to a flexible material, and which maintains its original shape. For example, the rigid material may be thick plastic, metal, wood, and the like.

The lower bar 200 may include a plurality of through holes 210. In the embodiment shown in FIG. 1, the lower bar 200 is illustrated as including five through holes 210.

One end of the plurality of connecting bars 300 is fixed to one surface of the upper bar 100 between the upper bar 100 and the lower bar 200 and the other end is fixed to a plurality of through holes 210 of the lower bar 200 As shown in Fig. The plurality of connecting bars 300 may be formed of the same rigid material as the lower bar 200, but may be formed of both a flexible material and a rigid material.

The fixing member 400 is attached to the lower bar 200 to fix the movement between the plurality of connecting bars 300 and the lower bar 200. More specifically, the connecting bar 300 extends through the plurality of through holes 210 of the lower bar 200 and the lower bar 200 is movable along the connecting bar 300, (300) is guided by the through hole (210) and is movable in the through hole (210). That is, although the lower bar 200 and the plurality of connecting bars 300 are movable relative to each other, the fixing member 400 is movable between the lower bar 200 and the plurality of connecting bars 300 Can be fixed.

The extent to which each of the plurality of connecting bars 300 extends beyond the corresponding through hole 210 or the degree to which each of the plurality of connecting bars 300 is moved may be different. For example, when the flexible upper bar 100 is deformed to a specific shape, a plurality of connecting bars 300 extend through the plurality of through holes 210, and the fixing member 400 By fixing the movement of the connection bar 300 and the lower bar 200, the shape of the deformed upper bar 100 can be fixed.

That is, when the upper bar 100 is pressed on the side surface of the structure having a specific shape or curved surface to deform the upper bar 100 and then the plurality of connecting bars 300 are fixed with the fixing member 400, 100 can maintain a shape corresponding to the profile of the side profile of the structure.

The curvature measuring instrument 10 according to an embodiment of the present invention may be particularly useful when attaching a structure such as the lug 30 to a side surface of a large block constituting a ship, for example . Hereinafter, the process of attaching the curved surface block of the ship to the lug 30 using the curvature measuring instrument 10 according to an embodiment of the present invention will be described in detail.

FIG. 2 is a diagram schematically illustrating a process of compressing a curvature measuring instrument 10 according to an embodiment of the present invention onto a curved surface of a block of a ship.

FIG. 4 is an exemplary view schematically showing a process of cutting the lug 30 illustrated in FIG. 3 and attaching it to a corresponding curved surface of the ship block illustrated in FIG. 2. FIG.

Referring to FIG. 2, a large block 20 of a vessel having a curved surface CS is illustrated, and a curvature measuring instrument 10 according to an embodiment of the present invention includes a curved surface CS of a large block 20 . The upper bar 100 formed of a flexible material is deformed corresponding to the shape or profile of the curved surface CS of the large block 20. [ Depending on the deformation of the upper bar 100, the degree to which each connecting bar 300 extends beyond the lower through-hole 210 may be different. The fixing member can fix the movement of the connecting bar 300 with respect to the lower bar 200 and strictly the movement of the connecting bar 300 passing through the through hole 210. Accordingly, the shape of the deformed upper bar 100 can be supported and held by the connecting bar 300.

Referring now to Fig. 3, lugs 30 are illustrated as attachments attached to the large blocks 20. Fig. 3, the upper bar 100 of the curvature measuring instrument 10 according to an embodiment of the present invention is illustrated as being deformed and fixed to correspond to the curved surface CS of the large block 20 in FIG. The curvature measuring instrument 10 is disposed on one surface of the lug 30 to be cut. Next, for example, the curved surface shape of the upper bar 100 can be displayed on one surface of the lug 30 by using the pen (PEN) and the display means.

Although not shown, a portion of the lug 30 may be cut to fit the curved shape shown on the lug 30 through a cutter.

4, the lug 30 cut in Fig. 3 can be brought into close contact with the curved surface CS of the large block 20 corresponding to the cut shape. That is, the curved surface shape or profile of the curved surface CS to be attached to the large block 20 can be matched with the curved surface shape or profile of the lug 30 and the large block 20, Can be closely contacted.

The other end of the connection bar 300 can pass through the plurality of through holes 210 of the lower bar 200 and extend through the plurality of through holes 210. More specifically, in a position where one end of the connecting bar 300 is introduced into the lower surface of the upper bar 100, the upper bar 100 may include a plurality of upper openings 112 on its side. The fixing pin 110 can be inserted into the upper opening 112 in a state where the connecting bar 300 is introduced into the lower surface of the upper bar 100 and can be inserted into the opening formed near the one end of the connecting bar 300 So that one end of the connecting bar 300 and the upper bar 100 can be fixed with respect to each other.

Further, a socket nut may be attached to the other end of the connection bar 300. That is, the socket nut 320 may be attached to the other end of the connecting bar 300 projecting beyond the lower surface of the lower bar 200. The diameter of the socket nut 320 may be larger than the diameter of the through hole 210. This prevents the spring 310 from moving over the upper surface of the lower bar 200 through the through hole 210 of the lower bar 200, which is the other end of the connecting bar 300, despite the action of the elastic restoring force of the spring 310 .

In another embodiment of the present invention, a butterfly nut is exemplified as the fixing member 400. [ The lower bar 200 may include a plurality of lower openings 220 passing through the respective through holes 210 on its side. The butterfly nut may include a butterfly handle and a bolt, threads may be formed on the bolt and the lower opening 220, respectively, and the bolt and the lower opening 220 may be screwed to each other, And may be inserted into the through hole 210 through the lower opening 220. One end of the bolt of the butterfly nut is introduced into the through hole 210 by the turning action of the butterfly handle so that frictional force can be applied to the side of the connecting bar 300 inside the butterfly nut, And the movement between the connection bar 300 and the lower bar 200 can be fixed.
