実施例
以下に本発明の実施例を第１図にもとづいて説明する。[Detailed Description of the Invention] Industrial Application Field The present invention is applied to a ship's rudder. Regarding f4Ki. 2. Description of the Related Art As shown in FIGS. 3 and 4, a conventional rudder for a ship has one rudder plate 21 cut in half from the center of the rudder in the direction of travel of the ship and formed in advance into a predetermined shape. The frame of the rudder body 25 is constructed in a lattice shape by welding the vertical rudder + 23 with the mounting piece 22 welded in a T-shape over the entire length and the horizontal rudder frame 24 to a predetermined position on the inner surface. Thereafter, the remaining rudder plate 27 is formed in advance into a predetermined shape so as to cover the skeleton, and slot holes 26 are bored vertically and horizontally at predetermined intervals at positions corresponding to the vertical rudder bones 23 and horizontal rudder bones 24. The remaining rudder plate 27 is attached to the vertical rudder frame 23 by welding the inner peripheral end of the slot hole 26 and the outer surface of the mounting piece 22.
and the horizontal rudder frame 24, and weld the rudder front end portion 28 and rudder rear end portion 29 of both rudder plates 21 and 27, respectively.
After that, the upper and lower surfaces are covered with the nuchal plate 30 and the bottom plate 31, and the rudder body 2
In addition, 32 is the rudder stock material and 33 is the bottom bottle. Problems to be Solved by the Invention As described above, the rudder main body 25 is constructed by welding and fixing the vertical rudder ribs 23 and the horizontal rudder ribs 24 to the inner surface of the pre-formed rudder plate 21. Since the mounting piece 22 attached to the other side of the bone 24 and the inner peripheral end of the slot hole 26 provided in the remaining rudder plate 27 are welded to form an oval, a large number of slot holes 26 are formed in the remaining rudder plate 27. Not only does it take a lot of time to drill holes, but the rudder body 2
5 was heavy, which caused problems in terms of workability. Therefore, the present invention solves these problems all at once by eliminating the slot hole 26 and the horizontal rudder frame 24. Means for solving the problem: By sandwiching a plurality of vertical rudder bones between the top plate and the bottom plate, and covering both sides with rudder plates, the slots/holes and horizontal rudder bones are eliminated. The weight is reduced by eliminating the horizontal rudder bones that form the framework of the rudder body.Furthermore, by eliminating the slot 6 that was conventionally drilled in the rudder plate, the working time for machining is shortened, and It has the advantage of being easier to weld to the rudder bone. EXAMPLE An example of the present invention will be described below based on FIG.

効果がある．Reference numeral 1 denotes a rudder body, in which a plurality of vertical rudder bones 3, 3 are installed at predetermined positions of one rudder plate 2 that is partially opened from the center in the direction of movement when the ship's power is 0.
One side is welded, and the top and bottom of the rudder frame 3 are clamped and fixed between the top plate 4 and the bottom plate 5, and a plurality of strip-shaped divided rudder plates 7 constituting the other rudder plate 6 are attached to the vertical rudder bones 3, 3. between the other side, and between the front edge 8 and the front edge of the vertical rudder 3, and the rear green part 9
and the last vertical rudder bone 3 ft! The rudder body l is constructed by welding and fixing the two sides of the split rudder plate 7 and the vertical rudder frame 3 to each other. Note that 10 is the rudder stock and 11 is the bottom pintle. Other Embodiments Next, another embodiment of the present invention will be explained based on FIG. 1 is the rudder body, which has a top plate 4 and a bottom plate 5 formed in advance.
The center rudder plate 12.12 is welded and fixed in a predetermined position on both sides of the central rudder plate 12. I to central vertical rudder bone 13
. On the other hand, a leading edge rudder plate 14 that forms the leading edge portion 8. 14 and leading edge vertical rudder? A trailing edge rudder plate 1 having a leading edge block 1G consisting of 15 parts and a trailing edge part 9 forming an ellipse.
7. 17 and a trailing edge block 1 consisting of a trailing edge vertical rudder bone 18
9 is inserted into the front and rear ends of the top plate 4 and bottom plate 5 of the rudder body 1, and the parts that contact the center rudder plates 12, 12 and the top plate 4 and bottom plate 5 are all welded and fixed to form the rudder body 1. do. Note that 10 is the rudder stock and 11 is the bottom pintle. Effects of the Invention Since the present invention is oval as described above, the weight is reduced by eliminating the horizontal rudder frame, and the machining time of the rudder plate is greatly shortened by eliminating the slot hole. Welding work to the rudder bone end surface becomes extremely easy, which improves work efficiency and has many benefits, including improved workability in transportation and installation.
