DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exterior folded plate used as an exterior wall material or a roofing material of a building.

[0002]

2. Description of the Related Art Among various types of exterior materials also called corrugated plates or corrugated plates, those made of metal plates are generally called folded plates (folded plates). Exterior folded plates used as exterior wall materials and roofing materials are formed by bending metal plates such as steel plates, aluminum plates, and copper plates by rolling or extruding, and providing peaks and valleys that repeat at regular intervals. Thus, the cross section in the width direction is formed to have a substantially waveform. By providing the substantially wave-shaped peaks and valleys, rigidity and bending strength are increased even with a thin metal plate, and therefore, they are often used as a light-weight, low-cost, exterior material suitable for a large span. Usually, in order to enhance the weather resistance, the surface is used after being subjected to a coating treatment such as water resistance and rust prevention.

As shown in FIG. 9, for example, as shown in FIG. 9, when the flat portion of the valley bottom of the exterior folding plate 1 is the bottom surface 11, the shape of the exterior folding plate is inclined from both side edges of the bottom surface 11 having a constant width toward the front side. 12 is raised, and a top surface 13 of a mountain parallel to the bottom surface 11 is provided at a constant width at the shoulder portion of the slope 12 so that the cross section in the width direction has a substantially trapezoidal waveform. The width of the bottom surface 11 and the top surface 13 and the angle and height of the slope 12 vary depending on the use and decorativeness. Further, the top surface 13 may be provided with shallow ridges or grooves 14 or the like to further enhance the strength and decorativeness.

When a plurality of exterior folded plates 1 are installed on an outer wall or a roof, usually, the direction of a mountain (valley) is made vertical and the edges are fixed at a constant width in order to improve drainage. They are arranged side by side in the width direction while overlapping. Therefore, one edge of the exterior folded plate 1 is formed in a shape overlapping with the other edge. In this example, as shown in FIG.
Slope 12 formed at the edge of exterior folded plate 1a on the tip side
a and the bottom surface 11a are adapted to receive the inclined surface 12b and the bottom surface 11b formed at the edge of the exterior folded plate 1b on the rear side. The shape of the overlapping portion at the time of the continuous installation is such that the overlapping surface is the slope 12 and the bottom surface 1 as described above.
In addition to one having two surfaces, one having two surfaces, namely, the slope 12 and the top surface 13. In addition, for example, there is a type in which only the bottom surface 11 or only the top surface 13 overlaps one by one, and another type in which the bottom surface 11, the slope 12 and the top surface 13 overlap each other.

[0005] Generally, when the exterior folded plate 1 is installed on the outer wall, as shown in Fig. 10, the bottom surfaces 11 are overlapped and screwed to a base material 41 such as a body edge. On the other hand, when installing on a roof, the top surfaces 13 are overlapped and fixed to a base material such as a purlin with screws or hook bolts.

[0006] In this specification, the edges overlapping each other at the time of continuous connection are referred to as receiving portions on the lower side, regardless of the number of surfaces, and overlapping portions on the upper side (front). , The receiving portion is denoted by the symbol A, and the overlapping portion is denoted by the symbol B in the figure.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 4 show an embodiment of an exterior folded plate 2 according to the present invention. This exterior folded plate 2
One unit plate is formed of one bent metal plate, and is formed to have three rows of peaks and four rows of valleys in a cross section in the width direction. The bottom surface 21 of the valley portion and the top surface 23 of the mountain portion are formed in parallel with each other, and the slope 22 that is continuous from the side edge of the bottom surface 21 to the side edge of the top surface 23 forms an angle of about 45 degrees with the bottom surface 21. I'm up. The top surface 23
It is wider than the bottom surface 21, and a shallow groove 24 is provided at the center of the top surface 23 to enhance decorativeness.

When the exterior folded plates 2 are successively provided in the width direction, the folded edge on the right side in the drawing is a receiving portion A, and the edge on the left side in the drawing is an overlapping portion B. As shown in FIG. 2, the receiving portion A is formed by two surfaces, that is, a rightmost slope 22a and a bottom surface 21a continuous with the slope 22a. Then, at the edge of the slope 22a, a folded portion P having a width of about 1/3 of the width of the slope 22a is formed toward the front side. On the other hand, as shown in FIG.
1b and a continuous slope 22b. At the edge of the bottom surface 21b, a folded-up portion Q having a mountain-shaped cross section that protrudes toward the front side is formed.

FIG. 4 shows that when the exterior folding plate 2 is used as an outer wall material and is continuously provided in the width direction, the adjacent exterior folding plates 2a,
2b shows a cross section of the overlapping portion.

Exterior folded plate 2a on the front side (left side in the figure)
On the bottom surface 21a serving as the receiving portion A, the bottom surface 21 serving as the overlapping portion B of the exterior folded plate 2b on the rear side (the right side in the drawing) is provided.
b is superimposed. Then, the overlapping bottom surfaces 21a, 2a
A tapping screw 51 or the like is driven into substantially the center in the width direction of 1b, and is fixed to the body edge 41 or the like serving as a base of the outer wall. At this time, between the bottom surface 21a serving as the receiving portion A and the folded-up portion Q formed at the edge of the bottom surface 21b serving as the overlapping portion B,
A gap S1 having a mountain-shaped cross section is formed.

Further, on the slope 22a serving as the receiving portion A of the exterior folded plate 2a on the front side, the slope 22b serving as the overlapping portion B of the exterior folded plate 2b on the rear side is overlapped. . At this time, as described above, since the folded portion P is formed at the edge of the slope 22a serving as the receiving portion A, the slope 22a serving as the receiving portion A and the slope 22b serving as the overlapping portion B are: The two sides are not in close contact with each other and are in line contact with both sides of the gap S2 having a substantially triangular cross section formed therebetween. This gap S2
Are formed such that the distance increases toward the edge of the slope 22a serving as the receiving portion A.

A feature of the exterior folded plate 2 of the present invention is that rainwater is prevented from entering the interior of the building by the action of the gaps S1 and S2 thus formed.

That is, the rainwater which wets the surface of the exterior folding plate 2 is moved from the side of the folded-up portion Q formed at the edge of the rear exterior folding plate 2b to the front exterior folding plate 2a. Along the surface of the contact portion and into the contact surface between the receiving portion A and the overlapping portion B. The rainwater first accumulates inside the first gap S1 formed on the back side of the folded-up portion Q. If the amount of rainwater is small, the infiltration of the rainwater can be stopped here. When the amount of rainwater is large, the rainwater infiltrates into the contact surface between the bottom surface 21a serving as the receiving portion A and the bottom surface 21b serving as the overlapping portion B due to capillary action. However, when the infiltrated rainwater reaches between the slope 22a serving as the receiving portion A and the slope 22b serving as the overlap portion B, the second water gap S2 is formed there, so that the rainwater collects here again. It will be. Since the distance between the second gaps S2 increases toward the front, the infiltration of rainwater due to the capillary phenomenon can be suppressed to a considerable extent here. As described above, two stages of gaps S1 and S2 are provided for the infiltration of rainwater to form pools, respectively, and a folded portion P is provided at the edge of the receiving portion A to form a so-called "water return". Thus, a greater effect of preventing flooding can be obtained as compared with the conventional folded plate 2 for exterior.

Next, another embodiment of the folded sheet for exterior of the present invention will be described with reference to FIGS.

The folded sheet 3 for exterior shown in FIG. 5 is formed to have four rows of peaks and three rows of valleys in a cross section in the width direction. The bottom surface 31 of the valley portion and the top surface 33 of the mountain portion are formed in parallel, and a slope 32 continuous from the side edge of the bottom surface 31 to the side edge of the top surface 33 is formed at an angle of about 45 degrees with respect to the bottom surface 31. I'm up. The bottom surface 31 is wider than the top surface 33.

When the exterior folding plates 3 are also connected in the width direction, they are superimposed as a receiving portion A on the right side in the drawing and a overlapping portion B on the left side in the drawing. As shown in FIG. 6, the receiving portion A is formed by three surfaces: a rightmost slope 321a, a top surface 33a and a slope 322a that are continuous with the slope 321a. Then, at the edge of the right slope 321a, a folded portion P having a width of about half the width of the slope 321a is formed toward the front side. On the other hand, as shown in FIG. 7, the overlapped portion B is formed by three surfaces: a leftmost slope 321b, a top surface 33b and a slope 322b that are continuous with the slope 321b. A folded-up portion Q having a semi-cylindrical cross section is formed at the edge of the left slope 321b.

FIG. 8 shows that when the exterior folded plate 3 is used as a roofing material and is continuously provided in the width direction, the adjacent exterior folded plate 3 is used.
The cross section of the part where a and 3b overlap is shown.

Exterior folded plate 3a on the front side (left side in the figure)
On the top surface 33a serving as the receiving portion A, the top surface 33 serving as the overlapping portion B of the exterior folded plate 3b on the rear side (the right side in the drawing).
b is superimposed. And, the overlapping top surfaces 33a, 3
A through hole is provided substantially in the center in the width direction of the hook bolt 5b.
2 are inserted and fixed to a purlin 42 or the like that is a base of the roof.

At this time, a gap S1 having a semicircular cross section is formed between the slope 321b on the left edge of the overlapped portion B having the folded-up portion Q formed at the edge and the slope 322a for receiving the slope. Also, a slope 321a at the right edge of the receiving portion A having the folded portion P formed at the edge and a slope 322b overlapping the slope 321a.
A gap S2 having a substantially triangular cross section is formed between the gaps S1 and S2. The gap S2 is formed such that the gap becomes wider toward the edge of the slope 321a serving as the receiving portion A.

In this embodiment, as in the above-described embodiment, the two gaps S1 and S2 serve as two-stage pools for rainwater intrusion, and are provided at the edge of the receiving portion A. The folded portion P becomes a "water return" and prevents infiltration of rainwater by capillary action, so that a great effect of preventing flooding can be obtained.

The shapes of the peaks and valleys formed on the folded sheet of the present invention are not limited to those shown in the above-described two embodiments. The number of peaks and valleys may be increased or decreased, the width may be changed, and the cross-sections of the peaks and valleys may be more complicated. The number of surfaces of the receiving portion and the overlapping portion that are superimposed at the time of the continuous installation may be determined in accordance with the cross-sectional shape of the valley and the construction state, and thus four or more surfaces may overlap each other.

When the exterior folded plate of the present invention is applied to an outer wall or a roof, the valleys may be oriented vertically or horizontally. However, when the sheets are superimposed sideways, the upper folded sheet is overlapped on the front side of the lower folded sheet.

A folded portion provided at an edge of the receiving portion;
And the shape of the folded portion provided at the edge of the overlapping portion is
The present invention is not limited to those shown in the embodiment of the example, but includes shapes slightly modified. For example, substantially the same effect can be obtained even if the folded portion is formed into a cylindrical shape instead of a folded shape, or if the folded portion is formed to have a substantially trapezoidal cross section. Obtainable.

By the way, according to the folded plate for exterior of the present invention,
In addition to the effect of preventing infiltration of rainwater, the following additional effects can be obtained.

That is, since the folded portion is formed on one edge of the exterior folded plate, the safety at the time of handling is higher than that of a conventional ordinary exterior folded plate whose edge is cut off. Therefore, it is possible to prevent an accident in which the hand slips when the exterior folding plate is vertically lifted and the hand is cut at a sharp edge portion.

Furthermore, in the case of a conventional general exterior folded plate whose edges are cut off, when a large number of sheets are stacked for transportation or storage, each exterior folded plate is in close contact with the entire surface. Then, there is an inconvenience that it is difficult to remove the individual sheets one by one, and it is necessary to insert a screwdriver or the like into the gaps between the folded sheets for exterior use and peel them off. However, since the folded plate for exterior of the present invention has a folded portion at one edge, the edges do not adhere to each other when stacked, and the work of taking out one sheet at a time can be easily performed.

Further, since the folded plate for exterior of the present invention is provided with a folded portion or a folded portion at the edge, the rigidity as a face material can be enhanced.

[0033]

According to the exterior folded plate according to the first aspect of the present invention, since the folded portion facing the front side is formed at the edge of the receiving portion, the overlapping portion and the receiving portion can be formed. An air gap is formed between them. The gap prevents rainwater from entering from the contact surface between the overlapped portion and the receiving portion due to the capillary action, and prevents rainwater from entering the interior of the building.

According to the exterior folding plate of the second aspect, since the folded portion having a substantially mountain-shaped cross section that protrudes to the front side is formed at the edge of the overlapped portion, the overlapped portion and the receiving portion are formed. Rainwater that enters from the contact surface with the water will accumulate in the gap formed on the back side of the folded part, and the amount of rainwater that enters the contact surface between the overlapping part and the receiving part should be reduced at an early stage of the flooding Can be.

Further, according to the exterior folded plate according to the third aspect, the effect of the exterior folded plate according to the first aspect is:
Combined with the effect of the exterior folded plate according to the second aspect, a more reliable effect of preventing inundation can be obtained.
