The parapet improves the design of the exterior of the eaves of the flat roof, and performs functions such as handrails on the rooftop.

FIG. 4 is a schematic sectional view showing the structure of such a conventional eaves structure of a flat roof. As shown, a flat roof surface is formed by a folding plate 10. The folding plate 10 is installed to be inclined so as to gradually descend to the outside of the building, and its cross section is formed into a concavo-convex shape that is continuous at a predetermined interval so that rainwater or the like flows in a concave groove extending in the inclination direction. Have been. The folded plate 10 is attached to a beam 14 provided above the outer wall 12 via an arm 16.

[0004] An eaves arm 18 is mounted outside the beam 14 so as to protrude outward by a predetermined length, and a parapet 20 as a nose tip cosmetic material is provided at the tip thereof. This parapet has a predetermined width in the vertical direction and extends around the building along the eaves.

The height of the upper end of the parapet 20 is higher than the tip of the folding eaves 10 on the eaves side, and an eaves cover 22 is provided between the parapet 20 and the folding 10.
It is provided so as to incline downward. The eaves cover 22 is installed to close a gap between the eaves end of the folding plate 10 and the parapet 20. The eaves cover 22 prevents leaves and the like from entering the eaves portion. I have. An end of the eaves cover 22 on the folding plate 10 side is fixed to an upper surface of the convex portion 10b of the folding plate 10 by a bolt 24 or the like.
A dust avoiding portion 22a extending from above is provided in the concave groove 10a. The dust avoiding portion 22a extends to a position slightly higher than the bottom surface of the concave groove 10a of the folding plate 10 so as to block large dust and the like flowing through this portion.

An eaves gutter 26 is provided below the eaves edge of the folded plate 10 so that it receives water or the like flowing down from the folded plate 10 and flows down to the vertical gutter 28 side. .

[0007]

In the eaves structure of a flat roof having the above structure, when rainwater or the like flows through the concave groove 10a of the folding plate 10, trash such as leaves and mud that fell on the roof surface is washed away. The eaves are blocked by the dust avoiding portion 22a of the eaves cover and accumulated in that portion. Accordingly, the gap between the lower end of the dust avoiding portion 22a and the bottom surface of the concave groove 10a of the folded plate 10 may be blocked by the mud or the leaves of the tree, and rainwater or the like may be dammed. In such a case, the concave groove 10a
Water gradually accumulates in the portion, reaches the upper surface of the convex portion 10b, and overflows. In this case, the folding plate 10 is configured to form a roof surface by combining a plurality of pieces, and since the overlapping portion, which is a connection portion thereof, is provided on the upper surface of the convex portion 10b, water is supplied to the convex portion 10b. When the water reaches the upper surface of the roof, rainwater may enter the roof from the portion.

As a result, there has been a situation in which the components of the roof portion are deteriorated, and furthermore, water leaks into the room or the like.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to always maintain a good water flow state even when the concave groove portion of the folding plate is clogged with dust at the portion where the eaves cover is placed on the folding plate. The purpose of the present invention is to provide a rooftop eave structure that can be used.

[0010]

According to a first aspect of the present invention, there is provided an eaves structure of a flat roof, wherein a cross section is formed in a concavo-convex shape such that concave grooves are formed at predetermined intervals. A folded plate that is a roof surface component that allows rainwater or the like to flow outward in the concave groove, and an upper end provided at the tip of an eave portion that projects further outward than the tip of the eaves of the folded plate has the upper end thereof A parapet at a position higher than the eaves edge of the plate, an eaves cover that spans and covers a gap between the parapet and the folded plate between an upper end of the parapet and an upper surface of the folded plate, In the eaves structure of a flat roof having eaves gutters installed below the eaves side edge of the folded plate and receiving rainwater that has fallen from the folded plate, and the upper surface of the convex portion of the eaves edge side predetermined portion of the folded plate. The height position is lower than the other parts by the inclination of the roof of the folded plate itself. Lower, the folded side end of the eaves cover is installed in a predetermined area of the folded plate, and is bent downward, and the lower end surface thereof is shaped along the uneven surface of the folded plate and from the uneven surface. It is characterized in that it is fixed so as to keep a state separated by a predetermined interval.

[0011] On the other hand, according to the eaves tip structure of the flat roof according to the second aspect, the predetermined area in which the height of the upper surface of the protruding portion of the folding plate is lowered is replaced with the predetermined area portion of the other part of the folding sheet. It is characterized in that it is configured to be inclined downward at an angle steeper than the downward inclination angle.

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

[0013]

According to the eaves structure of a flat roof according to claim 1,
If the gap between the bottom of the groove of the folded plate and the part bent downward on the folded side end of the eaves cover is blocked by mud or leaves, rainwater will collect and the water level will rise. Will be done.

[0014] Further, although the spill overflows over the upper surface of the convex portion of the folded plate, the height of the upper surface of the convex portion is formed lower in a predetermined region of the folded plate where the eaves cover is installed than in other portions. In addition, the upper surface of the convex portion and the eaves cover are maintained in a state of being separated from each other by a predetermined distance, not in a state where the whole is in contact with the upper surface.

Therefore, even when the groove is closed by dust clogging or the like, water flows into the eaves side of the folded plate from the upper surface side of the convex portion in the predetermined area. The flowing water falls from the tip of the eaves and is received by the eaves below.

As described above, in the portion where the folded eaves cover is installed, the height position of the upper surface of the convex portion is lower than the other portions, and water flows from the upper surface of the convex portion to the eaves side. So
As in the prior art, it is possible to effectively prevent the concave groove portion from being clogged and water from entering the folded joint portion of the convex portion to cause water leakage in the roof.

According to the eaves structure of the flat roof according to the second aspect, the lower part of the upper surface of the convex portion formed in the predetermined area of the folding plate is made to have the folding plate smaller than the other parts. Since it is configured by being inclined down at a steep angle, the inflow of water from the upper surface of the convex portion in a state where the groove of the folding plate is clogged can be made smoother. That is, since the predetermined region of the folded plate is inclined downward at a steeper angle, the area for storing overflowing water can be made larger, and the speed of inflow of water on the upper surface of the convex portion also increases. It is based on what you can do.

[0018]

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

FIG. 1 is a schematic explanatory view showing the configuration of an embodiment of the present invention. Elements similar to those of the conventional eaves structure shown in FIG. 4 are denoted by the same reference numerals.

The feature of the present invention lies in the configuration of the folded plate 10 and the configuration of the dust avoiding portion 22a of the eaves cover 22.

That is, the height of the protruding portion 10b in the predetermined area X at the edge of the eaves is adjusted by the height of the folding plate 10.
Is greatly reduced more than the descending amount due to the descending inclination of.

The eaves cover 22 is made of the parapet 2 as in the prior art.
One end is locked to the upper end of the “0”, and the other end is installed on the folded plate 10 side. The folded plate 10 side is not fixed to the upper surface of the convex portion 10b of the folded plate 10 but is installed in a state where the concave groove and the upper surface portion of the convex portion are separated from each other by a predetermined distance. I have. That is, the dust avoiding portion 22a formed by bending the end of the eaves cover on the folded plate 10 side downward has a shape such that the lower end surface is along the uneven surface of the folded plate 10, and the lower end surface is It is installed so as to be kept at a predetermined distance from the uneven surface of the folding plate 10. The fixing of the eaves cover 22 to the folding plate 10 is preferably performed between a predetermined portion and the upper surface of the convex portion of the folding plate 10 although not shown.

FIG. 2 is a schematic partial perspective view showing the configuration of the folding plate 10 and the eaves cover 22 more specifically.
In the case of 0, the cross section has an uneven shape so that the concave grooves 10a are formed at predetermined intervals, and the concave grooves 10a and the convex portions 10b are alternately continuous. The area X at the side edge of the eaves is configured such that the height of the protruding portion 10b is reduced. The eaves cover 22 includes the parapet 20 and the area X of the folded plate 10.
It is installed by being hung between the parts. At the end of the eaves cover 22 on the folded plate 10 side, there is formed a dust avoiding portion 22a having a lower end surface having a shape corresponding to the uneven shape of the outer surface of the folded plate 10 (that is, a continuous uneven shape). The dust avoiding portion 22a is installed such that the lower end thereof is separated from the surface of the folded plate 10 by a predetermined distance.

Next, the operation of the eaves 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 or the like, the rainwater is blocked and the water level rises.
First, the upper surface of the convex portion 10b in the region X of the region 0 is exceeded. In this case, when the eaves cover 22 is installed in contact with the entire upper surface of the convex portion as in the related art, 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 protruding 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 the ten folded houses. And it falls from there and will be received by the eaves gutter 26. Therefore, the rainwater is fold 10
Of the convex portion 1 even when damped by the concave groove 10a
0b smoothly flows into the eaves gutter 26 from the upper surface side, and effectively avoids the intrusion of water into the roof from the joint portion of the upper surface of the convex portion 10b of the folding plate 10 and further leakage into the room. be able to.

FIG. 3 shows another embodiment of the present invention. The characteristic feature of this embodiment is that the predetermined area X at the edge of the eaves of the folding plate 10 is inclined down at a steeper angle than the other parts. That is. As a result, the convex portion 10b in the region X
Can be made lower than other parts. Also, since this portion is inclined down steeply, the flow of rainwater is extremely smooth. The configuration of the eaves cover 22 is the same as that of the above-described embodiment, and water flows in from the upper surface side of the convex portion 10b in the region X. Thereby, the concave groove 10 of the folding plate 10 is formed.
Even when the portion a is clogged with dust and the flow of water is blocked, it is possible to smoothly flow the water toward the eaves gutter 26 in the region X.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention. For example, the width of the region X of the folding plate 10 can be variously adjusted in accordance with the size of the roof or the rainfall in the constructed area.

[0028]

As described above, according to the roof roof eaves structure according to claims 1 and 2, dust is clogged in the concave groove at the place where the eaves cover of the folded plate constituting the roof surface portion of the roof is raised, and the water level rises. Even in this case, it is possible to flow water into the lower eaves gutter from the upper surface side of the convex portion of the folding plate.

As a result, it is possible to effectively prevent rainwater from penetrating from the folding plate joint portion on the upper surface of the convex portion of the folding plate and leaking into the roof and further into the room.
