BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a draining material interposed on a roof or an outer wall of a building.

[0002]

2. Description of the Related Art As this kind of draining material, for example, the one shown in FIG. 6 has been conventionally used. In the figure,
Reference numeral 30 denotes a draining material according to the present embodiment. The draining material 30 is formed by bending a draining plate 32 interposed on the back surface of one end of a roof tile 31 and one end in the width direction of the draining plate 32 upward. With a folding part 33,
At the other end of the draining plate 32, a rising plate 35 having another bent portion 34 at the upper end is provided.

[0003] Reference numeral 36 denotes a draining ridge for draining rainwater entering between the roof tile 31 and the draining plate 32 in the longitudinal direction of the draining plate 32, and conventionally, the draining ridge 32 is located halfway in the width direction of the draining plate 32. multiple locations with is formed by bulging the upper surface of the projecting height h of the water-shielding ridge 32 has been set to be substantially the same as the protruding height h ₀ of the goby folded portion 33.

[0004]

[Problem to be Solved by the Invention] When the roof tile 31 is mounted on the drain plate 32 of the drain material 30, the drain tile 32 supports only one end of the roof tile 31, so that the roof tile 31 is broken. it may be placed in a slightly inclined relative to the projecting height h ₀ min only water-shielding plate 32 of the folding unit 33. Therefore, in the above-described conventional technique, a gap 37 is generated between the end of the roof tile 31 and each drainage ridge 36 due to the inclination of the roof tile 31, and rainwater easily enters from the gap 37, and the roof This was the cause of the deterioration in waterproofness.

[0005] On the other hand, it is conceivable to fill the gap 37 later with a sealing material or the like, but this requires a high material cost and construction labor. In view of such circumstances, an object of the present invention is to improve waterproofness between an exterior material such as a roof tile and a drainage material without requiring post-processing of a sealing material or the like.

[0006]

In order to achieve the above object,
The technical measures taken by the present invention include a draining plate 10 wrapped and interposed on the back surface of one end of the exterior material 4 and one end of the drainage plate 10 in the width direction bent to the exterior material 4 side. And a plurality of draining ridges 16 that are parallel to the longitudinal direction of the draining plate 10 and protrude to the same side of the draining plate 11 in the width direction of the draining plate 10. In the draining material formed at intervals in the width direction of the plate 10, the projecting height of each of the draining ridges 16 is set so as to gradually increase as the distance from the fold portion 11 increases.

[0007]

[Function] Each draining ridge 16 has a protrusion height h ₁ h ₂ h ₃ h _4.
Since it is set so as to gradually increase as it separates from the gauze fold portion 11, even if the exterior material 4 is inclined with respect to the drain plate 10, it reliably contacts the back surface of the exterior material 4 and rainwater from the outside. To prevent intrusion.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a case where the draining material according to the present invention is employed near a flow wall of a building roof. In the figure, reference numeral 1 denotes a field board, the lower side of which is supported by rafters 2 and the asphalt roofing 3 is laid on the upper side thereof. Is laid.

Numeral 5 is a rim extending along the roof flow direction on the wall side, and nails the outer wall plate 7 through the asphalt roofing 3 and the asphalt felt 6 stretched on the wall side.
Supported by stops. Numeral 9 denotes a drainer, which is formed by bending a long steel thin plate into a substantially L-shaped cross section, and is wrapped around the back surface of one end of the roof tile 4 to be interposed.
And one end in the width direction of the draining board 10 upward (the roof tile 4 side)
A bent portion 11 is formed in a bent shape. Drain board 10
From the other end in the width direction of the receiving section 12
13 is formed integrally, and a rising plate 14 is integrally erected from the wall side end of the housing portion 13. At the upper end of the rising plate 14, another fold 15 is formed.

Reference numeral 16 denotes a draining ridge provided on the draining plate 10 and a roof tile.
This is for draining rainwater that has entered between the drain board 4 and the drain board 10 in the longitudinal direction of the drain board 10. This draining ridge 16 is
Are formed at intervals in the width direction such that a plurality of portions (four in this embodiment) in the width direction are bulged to the upper surface side, that is, to the same side as the fold portion 11. Ridge 16
Each is parallel to the longitudinal direction of the draining plate 10.

[0011] As shown in FIG.
The protruding height h ₁ h ₂ h ₃ h ₄ is set so as to gradually increase linearly from the side closer to the fold 11 to the side farther, so that the roof tiles 4 Even in a state inclined with respect to the draining plate 10, each draining ridge 16
The upper end of the roof tile 4 reliably contacts the lower surface of the roof tile 4, and it is possible to prevent rainwater from entering the back side of the roof tile 4 even in a strong wind or the like.

Further, since each of the drainage ridges 16 surely comes into contact with the back surface of the roof tile 4, even if an operator steps on the roof tile 4 during construction, the roof tile 4 is not cracked. There is an advantage that it can be prevented. Reference numeral 17 denotes a steel rain gutter, which is mounted on the storage portion 13 of the draining material 9 so as to cover a cap 19 secured with a nail 18 from above, and a sealing material is provided between the roof gutter 4 and the roof tile 4.
20 are interposed.

[0013] As shown in FIG.
Long elastic bodies 21 and 22 made of rubber or the like and having different cross-sectional heights can be formed by being fixed to the upper surface of the draining plate 10, respectively. In this case, needless to say, the elastic body 21 on the left side of the figure is set to have a slightly higher cross-sectional height than the elastic body 22 on the right side.
The elastic members 21 and 22 follow the roof tile 4 even if the inclination of the roof tile 4 slightly changes, so that the waterproof property can be further improved.

The draining material 9 according to the present invention can be used as a draining material 9 not only for the above-mentioned flow wall of the roof but also for the roof flare as shown in FIG. As shown in the figure, it can also be used as a draining material 9 arranged in the middle of the roof in the roof flow direction. Further, as shown in FIG. 5, a draining material interposed at the outer corner of the outer wall of the building
9 can also be adopted. In FIG. 5, reference numeral 23 denotes a column member, 24 denotes a vertical trunk edge fixed to the column member 23, and 25 denotes an outer wall material (exterior material) fixed to the vertical trunk edge 24. In this case, the draining material 9 is In order to finish the outside corner of the corner
It is interposed between both outer wall members 25, 25 orthogonal to each other.

[0015]

[Effects of the Invention] As described above, according to the present invention,
Even when the exterior member 4 is arranged at an angle with respect to the draining plate 9, the draining ridges 16 contact the back surface of the exterior member 4 to prevent rainwater from entering from outside, so that a sealing material or the like is used. It is possible to improve the waterproofness between the exterior material 4 and the draining material 9 without requiring post-construction, thereby contributing to the improvement of the durability of the whole building.
