[0007]

In the eaves eaves structure of the flat roof having the above structure, when rainwater or the like flows through the groove 10a of the origami plate 10, dust such as leaves and mud dropped on the roof surface is washed away. The eaves cover is clogged at the dust avoiding portion 22a, and is collected at that portion. Therefore, the mud and the leaves may block the lower end of the dust avoiding portion 22a and the bottom surface of the recessed groove 10a of the orthographic printing plate 10 to block rainwater. In such a case, the groove 10a
Water gradually accumulates in the portion, reaches the upper surface of the convex portion 10b, and overflows. In that case, the origami plate 10 is configured so that a plurality of pieces are combined to form a roof surface, and the overlapping portion, which is a connecting portion thereof, is provided on the upper surface of the convex portion 10b, so that the water is convex portion 10b. If it reaches the upper surface of the roof, rainwater may intrude into the roof from that portion.

As a result, the constituent members of the roof portion are deteriorated, and further, water leakage to the indoor side occurs.

The present invention has been made in view of the above circumstances, and an object thereof is to always ensure a good running water state even when the concave groove portion of the folding plate is clogged with dust in the installation portion of the eaves cover on the folding plate. It is to provide a flat roof eaves structure that can be done.

[0010]

In order to achieve the above-mentioned object, the eaves tip structure of a flat roof according to claim 1 is formed in a concavo-convex shape having continuous cross sections so that concave grooves are formed at predetermined intervals. A folding plate, which is a roof surface component that allows rainwater and the like to flow outward in the groove, and an upper end of the eave portion that projects further outward than the eaves tip of the folding plate, and the upper end thereof is the folding plate. A parapet at a position higher than the edge of the plate on the eaves side, and an eaves cover that covers the gap between the parapet and the folding plate by being spanned between the upper end of the parapet and the upper surface of the folding plate, In the eaves edge structure of a flat roof having an eaves gutter installed below the eaves side edge of the origami plate and receiving rainwater falling from the origami plate, and the upper surface of the convex portion of the eaves side edge predetermined region of the origami plate. The height position is higher than that of other parts by the amount of descending due to the roof inclination of the plate itself The lower end of the eaves cover on the folding plate side is installed in a predetermined region of the folding plate, and is bent downward so that its lower end surface has a shape along the uneven surface of the folding plate and from the uneven surface. It is characterized in that they are fixed so that they are kept at a predetermined distance.

On the other hand, according to the flat roof eaves structure of the second aspect, in the predetermined region in which the upper surface height position of the convex portion of the plate is lowered, the predetermined region portion is the same as the other portion of the plate. It is characterized in that it is configured by descending and inclining at a steeper angle than the descending and inclining angle.

The means for fixing the eaves cover to the fold plate side is not limited, and it can be fixed by providing a fixing member at a predetermined position of the convex portion of the fold plate. is there.

[0013]

According to the flat roof eaves structure of claim 1,
If the gap between the bottom of the groove of the origami plate and the part of the eaves cover that bends downward on the origami plate side is blocked with mud or leaves, rainwater will accumulate and the water level will rise. Will be done.

Further, although it overflows beyond the upper surface of the convex portion of the plate, the height of the upper surface of the convex portion is lower than that of other portions in a predetermined region of the plate where the eaves cover is installed. In addition, the upper surface of the convex portion and the eaves cover are not kept in contact with each other as a whole but are kept at a predetermined distance.

Therefore, even when the concave groove portion is blocked by dust clogging or the like, in the above-mentioned predetermined region, water will flow from the upper surface side of the convex portion to the eaves side of the plate. Then, the water that flows in falls from the tip of the eaves of the origami plate and is received by the eaves gutter below.

As described above, the height of the upper surface of the convex portion is lower in the portion where the eaves cover of the origami plate is installed than in other portions, and water flows from the upper surface of the convex portion to the eaves side. So
It is possible to effectively prevent the fact that the concave groove portion is clogged and water leaks into the roof due to water invading the plate-shaped joint of the convex portion as in the conventional case.

Further, according to the flat roof eaves structure of the second aspect, a portion of the convex portion formed in a predetermined region of the plate having a lower upper surface height position is formed in the plate more than other portions. Since it is configured by descending and sloping at a steep angle, it is possible to make the inflow of water from the upper surface of the convex portion in a state where the concave groove of the origami plate is clogged more smoothly. That is, since the predetermined area of the letterpress is inclined downward at a steeper angle, the overflow water storage area can be increased and the inflow of water on the upper surface of the convex portion also increases its speed. It is based on what you can do.

[0018]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a schematic explanatory view showing the structure of an embodiment of the present invention, in which elements similar to those of the conventional eaves tip structure shown in FIG. 4 are designated by the same reference numerals.

Characteristic parts of the present invention are the structure of the folding plate 10 and the structure of the dust avoiding portion 22a of the eaves cover 22.

That is, the folding plate 10 has the height of the convex portion 10b in the predetermined area X at the edge of the eaves side, and
It is greatly reduced more than the amount of the descent due to the descent.

The eaves cover 22 is the parapet 2 as in the conventional case.
One end side is locked to the upper end portion of 0 and the other end side is installed on the folding plate 10 side. Then, the folding plate 10 side is not fixed to the upper surface of the convex portion 10b of the folding plate 10 but is installed in a state where the concave groove and the upper surface of the convex portion are separated from each other for a predetermined period. There is. That is, the dust avoiding portion 22a formed by bending the end portion of the eaves cover on the plate 10 side downward has a shape such that its lower end surface is along the uneven surface of the plate 10, and its lower end surface is It is installed so as to be separated from the uneven surface of the origami plate 10 by a predetermined distance. Although not shown, the eaves cover 22 is preferably fixed to the folding plate 10 at a predetermined position between the eaves cover 22 and the upper surface of the convex portion of the folding plate 10.

FIG. 2 is a schematic partial perspective view showing the structure of the folding plate 10 and the eaves cover 22 more concretely.

The height of the convex portion 10b in the region X on the edge of the eaves side is reduced. The eaves cover 22 is the area X of the parapet 20 and the origami plate 10.
It will be installed by being bridged between the part and. A dust avoiding portion 22a having a lower end surface having a shape (that is, a continuous uneven shape) corresponding to the uneven shape of the outer surface of the folding plate 10 is formed at an end portion of the eaves cover 22 on the folding plate 10 side. Then, the lower end of the dust avoiding portion 22a is installed so as to be kept separated from the surface of the origami plate 10 for a predetermined period of time.

Next, the operation of the eaves tip structure having the above structure will be described with reference to FIG.

When the gap Y between the concave groove 10a of the folding plate 10 and the lower end of the dust avoiding portion 22a of the eaves cover 22 is clogged with dust, the rainwater is dammed up and the water level rises, the folding plate 1
The upper surface of the convex portion 10b in the region X of 0 is first crossed. In this case, when the eaves cover 22 is installed in contact with the entire upper surface of the convex portion as in the conventional case, water does not flow in and the water level further rises. However, in the present invention, as shown in the figure, the eaves cover 22 is not in contact with the portion of the convex portion 10b in the region X, and a predetermined interval is provided. Therefore, the water whose water level has risen flows into the gap between the upper surface of the convex portion 10b and the dust avoiding portion 22a. The flowing water flows to the tip of 10 origami plates. Then, it falls from there and is received by the eaves gutter 26. Therefore, the rainwater is the origami version 10.
Even if it is dammed by the concave groove 10a of the

It is possible to make the height position of the lower than that of other parts. In addition, since this part is inclined at a steep angle, rainwater can flow in very smoothly. The structure of the eaves cover 22 is similar to that of the above-described embodiment, and water flows in from the upper surface side of the convex portion 10b in the area X thereof. Thereby, the groove 10
Even if dust is clogged in the portion a and the flow of water is stopped, the water can be smoothly poured into the eaves gutter 26 side in the area X.

The present invention is not limited to the above embodiments, but various modifications can be made within the scope of the invention. For example, the width of the area X of the origami plate 10 can be variously adjusted according to the size of the roof or the amount of rainfall in the area to be constructed.
