Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a corrugated member having a rectangular corrugated cross-sectional shape.

[0002]

2. Description of the Related Art A corrugated member is a corrugated member having a curved or rectangular cross-section and is corrugated. It is widely used as a roofing material, and is also used for walls and soundproof walls.

[0003]

However, the conventional corrugated member is merely formed in a corrugated form, and there is only a flat corrugated member as a whole. Therefore, when such a corrugated member is used to roof the roof, it becomes a flat single-sided gable roof or gable roof, which is only used in factories and warehouses, and is extremely useful as a roofing material. However, it was a presence without any luxury.

[0004]

Therefore, the present inventor has accomplished the present invention as a result of earnest research in view of the above problems, and is characterized in that the cross section is formed into a rectangular corrugated shape. In the corrugated member, the peaks and troughs of the corrugated member are reversed and the inverted troughs and the inverted peaks are bent downward,
The troughs and the inverted troughs are adjacent to each other, and the troughs and troughs of the corrugated member are connected to each other. A straight ridge line is continuously provided on the connecting surface connecting the valley surfaces.

Alternatively, the inverted connecting surface is an isosceles triangle,
The connecting surfaces are respectively connected to both hypotenuses of the inversion connecting surface, and the valley surface connected to each connecting surface is connected in a bent shape at the apex portion of the inversion connecting surface.

Here, the corrugated shape having a rectangular cross section means a corrugated shape in which upper and lower substantially flat plate-shaped peaks and valleys are sequentially connected in a corrugated manner by substantially flat plate-shaped connecting surfaces. The bent corrugated member according to the present invention is characterized in that the peak surface and the trough surface are reversed in the middle of the flow direction so as to be bent in the flow direction of the corrugated member.

In the present specification, an inverted valley surface connected to the mountain surface is referred to as an inverted valley surface, and an inverted mountain surface connected to the valley surface is referred to as an inverted mountain surface. Also, for the connecting surface that connects the mountain surface and the valley surface,
A surface connecting the inverted valley surface and the inverted mountain surface is referred to as an inverted connection surface.
Then, the connecting surface and the inverted connecting surface are continuously provided in a straight line, and the valley surface and the inverted valley surface are positioned adjacent to each other. In other words, the inverted portion from the valley surface to the inverted peak surface is not the same position as the inverted portion of the peak surface and the inverted valley surface, but is a position closer to the front side. Also, for example, in the case of mountain and inverted valley,
Only one of them is reversed with respect to the other, and there is no master-slave relationship to them.

As another embodiment of the present invention, the inverted connecting surface is an isosceles triangle, the connecting surfaces are respectively connected to the two oblique sides of the inverted connecting surface, and the valley surface connected to each connecting surface is You may make it connect in a bent shape in the vertex part of an inversion connection surface. This is because when the idea of reversing the crest surface to the inverted trough surface and the trough surface to the inverted crest surface is applied to both sides of the corrugated member as described above, all the crest surfaces located at the center and the crest surface are the same. It is a state in which the valley surface and the connecting surface are deleted by the length and the remaining both ends are connected.

That is, when the unevenness of the peak surface and the valley surface is reversed on both sides of the corrugated member, since the connecting surface (reverse connecting surface) is trapezoidal, a rectangular portion having the same width as the upper base forming the trapezoid. By deleting the, the connecting surface (inverted connecting surface) becomes an isosceles triangle, and a bent corrugated member having no mountain surface (inverted mountain surface) can be obtained.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the drawings.

FIG. 1 shows an embodiment of a bent corrugated member 1 according to the present invention, in which a flat crest surface 2 and a trough surface 3 and a connecting surface 4 connecting the crest surface 2 and the trough surface 3 are connected. In the corrugated member formed by the above, the concavities and convexities of the crest surface 2 and the trough surface 3 are reversed and bent downward to connect the reversal trough surface 5 and the reversal crest surface 6, and the connection surface 4 to the reversal trough. By arranging the inversion connection surface 7 connecting the surface 5 and the inversion crest surface 6 continuously with a straight ridge line, the inversion connection surface 7 is bent in the flow direction of the corrugated member.

FIG. 2 is a developed view of the bent corrugated member 1 shown in this example.
Shown in The thin lines in the figure are mountain folds and the dotted lines are valley folds. As is apparent from this development view, the continuous positions of the crests 2 and the inverted troughs 5 are different from the continuous positions of the troughs 3 and the reversed crests 6, and the troughs 3 and the reversed troughs 5 are adjacent to each other. Become. This bent corrugated member 1
As a manufacturing method of, a plastic injection molding may be used, or an iron plate may be press-molded. When press-molding, the plate-shaped iron plate shown in FIG. 2 may be gradually molded into the shape shown in FIG. 1 through several steps. Further, in the figure, the connecting surface 4 and the reverse connecting surface 7 are formed so as to be vertical surfaces, but it is easier to process them if they are made into a tapered shape, and furthermore, a large radius is provided in the partition portion of each surface. You may have it.

FIG. 3 shows an example of a usage state of the bent corrugated member 1. This is one in which the bending corrugated member 1 is attached to an end portion of a roof 9 formed of a conventional corrugated member 8. By bending the eaves portion, the entire shape of the roof 9 can be greatly changed. In this case, a hole may be provided in a portion where the valley surface 3 and the inverted mountain surface 6 are connected to allow rainwater to flow down, and a trough may be provided below the hole.

FIG. 4 shows another embodiment of the bent corrugated member 1. Inverted troughs 5 and inverted crests 6 are provided on both sides of the corrugated member, respectively.
And the reverse connection surface 7 are connected in series. This is shown in Figure 2.

FIG. 5 shows still another embodiment of the bent corrugated member 1, in which the inverted connecting surface 7 is an isosceles triangle, and the connecting surfaces 4 are respectively connected to the two oblique sides of the inverted connecting surface 7. The valley surface 3 that is provided and is continuously provided to each connecting surface 4 is continuously provided in a bent shape at the apex portion of the reverse connecting surface 7. This is because the inverted connecting surface 7 is formed into an isosceles triangle so that the inverted mountain surface 6 is omitted and the valley surfaces 3 are directly connected to each other, as is apparent from the development view of FIG. 6.

FIGS. 7 (a) and 7 (b) show an example of the usage state of the bent corrugated member 1 shown in FIGS. 4 and 5, respectively, which should be formed on a mansard roof (a bent roof) or a silo-like roof. You can In particular, in the bent corrugated member 1 having the inverted connection surface 7 in the shape of an isosceles triangle, the bent corrugated member 1 has a curved shape as a whole rather than a bent shape, and it is possible to form a three-dimensional surface which has never existed while maintaining the corrugated shape. . Further, the bent corrugated member 1 is attached to the eaves portion of the roof 9, and FIG.
You may make it use it for the central ridge part of the roof 9 like this.

Such a bent corrugated member 1 can be used not only for roofing materials but also for walls, soundproof walls and the like. Since the wall is not flat like the conventional one, the image as a whole can be greatly changed. Also, as a soundproof wall,
Since the combination of the concavities and convexities is complicated and has a bent shape, it has a high sound absorbing effect and also has an effect of not letting noise escape to the outside, which is extremely useful as a soundproof wall for roads and the like. Further, it may be used as a wall material for a theater, a movie theater, an audio room or the like.
