Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Use of the Invention) The present invention relates to a corrugated plate used as a part of a fence or a structural material.

(Prior Art) A corrugated plate in which continuous corrugations are formed by one plate is known from Japanese Utility Model Publication No. 48-30007. In this corrugated plate, an inverted triangle having a base on the upper side and two other sides extending on the lower side is arranged on each slope, and cuts corresponding to the other two sides are provided, and the longitudinal direction of the slope of the corrugated plate is defined. Adjacent to the triangle, a triangle having a base on the lower side and another two sides extending upward is arranged, and a cut is provided on the other two sides, and these two types of triangles are formed in the longitudinal direction of each slope. Are alternately arranged, and the triangular portions surrounded by the cuts are bent upward or downward until they are parallel to the corrugated crests to project to form the connecting means, and the tips of these connecting means are overlapped and welded. It is made by doing. According to this structure, the weight can be reduced, and a strong corrugated plate can be obtained in the direction perpendicular to the corrugated peaks and in the direction in which the corrugated peaks extend. However, with this structure, it is very difficult to punch out a large number of cuts on two sides of a triangle on a single long large plate, bend it into a continuous corrugation, and project the triangular portion surrounded by the cuts as a connecting means. No, and it was virtually impossible to make.

In order to make up for this drawback, in Japanese Utility Model Publication No. 61-192012,
The corrugated plate is divided for each slope and formed by multiple independent slope plates, and the edges corresponding to the top and bottom of the corrugation are bent in opposite directions to form a joint. The corrugated plate can be processed by joining the respective joining portions to each other to form a corrugated shape, and joining the tips of the opposing triangular protrusions provided as the connecting means to each other. However, in addition to welding the triangular protrusions, it is very difficult to fold the longitudinal edges of each bevel plate to form two joints and weld these long joints into a large corrugated plate. There is a drawback that it takes time and labor and the manufacturing cost becomes high.

(Object of the Invention) An object of the present invention is to provide a corrugated plate that can be easily and economically manufactured.

(Structure of the Invention) In order to achieve the above object, according to the present invention, the triangular and inverted triangular holes alternately arranged on each slope of the corrugated plate formed by one plate are completely punched out. And the top and bottom and the bottom of the slopes facing each other at the ends of these connecting means by welding the heads of stamped die-cutting material or similar piece material to each other to form connecting holes. A corrugated plate formed by welding to the bottom may be provided.

(Effect of the Invention) According to the configuration of the present invention, when processing a large long plate material, after completely punching out the triangular holes and the inverted triangular holes alternately arranged on the corrugated slope, Since there is no step of bending the triangular protrusions only by bending this plate into a continuous corrugated shape, the work is easier than in the past.
Further, since the heads of the punched lightweight small triangular shaped blanks are welded to each other, both ends of the connecting means may be welded to the top and the top and the bottom and the bottom of the opposite slopes, so that a large plate material can be obtained. It is easy to handle and very easy to work, unlike the case where the triangular protrusions protruding from the slope are overlapped and welded together.

(Embodiment) An embodiment of the present invention will be described in detail below with reference to the drawings.

1, 2 and 3 are perspective views showing a corrugated plate according to the present invention.

The corrugated plate 1 has a large number of slopes 2 forming a continuous corrugation,
3, 4 and 5, between which the corrugated top 6 and corrugated bottom 7 are formed. The slopes 2 and 3 are located above the amplitude center line C of the waveform and at the top 6 of the waveform, respectively.
There are arranged triangular heart-shaped holes 11, 12 (FIG. 2) having a base 8 parallel to, and two other sides 9, 10 extending downward beyond the centerline C. Further, the triangular heart-shaped holes 11, 1 are formed in the longitudinal direction of the slopes 2, 3.
A triangular shape adjacent to 2, having a base 13 in a portion below the centerline C and parallel to the corrugated bottom 7, and two other sides 14, 15 extending upward beyond the centerline C. Heart-shaped holes 16, 17 (Fig. 3) are arranged. These triangular heart-shaped holes 11, 12 and 16, 17 are arranged alternately in the longitudinal direction of the slope. Adjacent to the mountain formed by the slopes 2 and 3, heart-shaped holes having the same triangular shape and inverted triangular shape are arranged for the mountain formed by the slopes 4 and 5. These triangular holes are
It is formed by punching out completely according to the present invention without making a projection by forming a cut on only two sides of a triangle and bending the remaining bottom as in the prior art. Therefore, the difficult process of bending can be omitted. The above arrangement of these triangular heart-shaped holes is shown in FIG. However,
As shown in FIG. 5, the triangular holes may be arranged so as to be offset in each row. The corrugated body may be manufactured by completely punching out triangular heart-shaped holes arranged as shown in FIGS. 4 and 5 on a flat plate and then bending the corrugated body into a predetermined corrugated shape.

In this embodiment, the triangular holes 11, 12, 16, 17
Is formed in a heart shape, with rounded corners at the top and bottom of the heart shape. By forming the heart-shaped hole in this manner, when a heart-shaped stamped material is used as the connecting means, there is an effect that it is easy to weld as described later. However, other triangular holes can also be used.

The punched triangular heart-shaped blank 18 is used as a connecting means 19 for connecting the tops 6 of the corrugated plate 1 according to the present invention. For this purpose, as shown in FIG. 6, the top portions 20 of the triangular shaped members 18 are overlapped and welded to each other to form the hourglass-shaped connecting means 19, and both ends thereof are corrugated top portions 6 of the corrugated plate 1. Weld them by touching # 6 and # 6 (FIG. 7). At that time, since both ends of the connecting means are heart-shaped bottoms and the center is recessed in an arc shape, there is an advantage that welding is very easy.
In this way, the inverted triangular heart-shaped holes
The corrugated tops of are connected by a connecting material. Similarly, as shown in FIG. 3, in the row B of triangular holes adjacent to the row A of inverted triangular holes, both ends of the connecting means 19 are applied to the corrugated bottom portions 7 and 7 and welded. In this manner, the corrugated bottoms of the row B of triangular holes are sequentially connected by the connecting means 19. Thus, a corrugated plate having a desired length is obtained.

In addition, in order to reinforce the corrugated plate, for example, as shown in phantom lines in FIG. 4 and its cross section in FIG. 9, convex elongated slender ridges are formed between the triangular heart-shaped holes. You can also do it. It is also possible to form similar elongated convex ridges as shown in FIGS. 10 and 11 to reinforce the triangular heart-shaped profile. Further, when welding the tops of the triangular heart-shaped die-cutting materials, it is also possible to bring the jointing surfaces formed by bending the heart-shaped die-cutting material at a right angle into contact with the joining surfaces for welding.

Further, in the embodiment of the present invention, the corrugated plate is formed in a flat shape, but in order to form a cylindrical corrugated plate, the corrugated plate is bent to form a cylindrical shape, and the corrugated peaks on the outside of the cylindrical shape are formed. It is also possible to connect the and the peaks with a long connecting means, and to connect the inner corrugated peaks with the short connecting means. It is also conceivable to form the corrugated plate into a conical shape.

As the material of the corrugated plate, metal, plastic, or other material can be used depending on the application.
