[Detailed Description of the Invention] [Industrial field of application] The present invention lays a drainage sheet for drainage on the wall between the outer wall of a building and the roof of a shed at the edge of the wall below the drainage to drain water. It relates to the underwater drainage structure near the roof wall.

[Prior Art] Conventionally, a draining sheet having an L-shaped cross section is laid along the wall as a base material between the outer wall of the building and the roof of the lower house, and the roof sheet of the lower house is placed on the draining sheet. The roofing material is roofed on top, and the exterior material is attached to the outer wall on the draining sheet.
Then, the water that has infiltrated into the ground side from between the exterior material and the roof material is received by the draining sheet, flows down the water along the draining sheet, and flows down to the gutter etc. from the end of the draining side. .

[Problems to be Solved by the Invention] By the way, there is no conventional guide for preventing water from going to the outer wall when it flows down from the water side end of the draining sheet, so that water goes to the outer wall side and water enters the outer wall. There was a risk of doing it.

The present invention has been made in view of the above-mentioned points, and the purpose of the present invention is to prevent water falling from the lower end of the water from going to the outer wall side at the draining projection, so that the water can enter the outer wall. Another object of the present invention is to provide a structure for cutting the underwater side of a roof wall that can prevent the occurrence of damage and can also serve as the same underwater drainage sheet on the left or right side of the roof of the lower house.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the underwater draining structure at the wall of the roof of the present invention has one side piece 3 and the other side piece 4 provided with an L-shaped cross section. Right and left triangular drainage projections 5 having a predetermined thickness are provided at the water lower ends of the side piece 3 and the other side piece 4 so as to be symmetrically adjacent to each other to form a drainage sheet A for underwater use. The above-mentioned underwater draining sheet A is arranged on the underwater side near the wall between the roof 2 of the shop, and one side piece 3 of the underwater draining sheet A is brought into contact with the outer wall 1 and the other side piece 4 is attached. The roof tile 13a for the starter, which is laid so as to contact the roof 2 of the lower house and is roofed on the roof 2 of the lower house, is placed on the underwater draining sheet A of the starter roof tile 13a, and the roof for the starter is also placed. The water draining projection 5 of the water draining sheet A is placed in the triangular notch 14 provided at the corner on the water side of the roof tile 13a. Is location, drainage gap between the notch 14 edge and draining projection 5
15 formed.

[Operation] The draining sheet A for underwater is attached to the wall by laying it so that one side piece 3 of the draining sheet A is in contact with the outer wall 1 and the other side piece 4 is in contact with the roof 2 of the lower house. It is possible to prevent water falling from the lower end of the water of the water draining sheet A from going to the outer wall 1 side at the water draining protrusion 5, and to prevent water from entering the outer wall 1. Furthermore, even if one side piece 3 of the drainage sheet A for underwater is laid on the roof 2 of the lower house or the other side piece 4 is laid on the roof 2 of the lower house, the draining protrusion 5 is located at the lower end of the water. The same drainage sheet A for underwater can be used on both the left and right walls of the roof 2 of the lower house. Further, the starter roof tile 13a can be roofed so that the draining protrusion 5 does not get in the way simply by providing the notch 14 at the corner near the wall of the starter roof tile 13a. Further, rainwater can be smoothly drained from the drainage gap 15 between the water draining protrusion 5 and the edge of the notch 14.

[Embodiment] As shown in FIG. 1, the underwater drainage sheet A of the present invention is formed in an L-shape with one side piece 3 and the other side piece 4, and is entirely formed of synthetic resin or rubber. Has been done. One side piece 3
At the position of the water side end of the inner corner between the side piece 4 and the other side piece 4, right-sided triangular draining projections 5 are symmetrically adjacent to both the one side piece 3 and the other side piece 4. It is provided in. An adhesive layer 6 is provided at an appropriate position on the back side of one side piece 3 and the other side piece 4 of the underwater drainage sheet A, and a release paper 7 is attached to the adhesive layer 6.

As shown in FIGS. 2, 3, and 5, a roof base sheet 10 made of a synthetic resin sheet is laid over the entire surface of the base 8 of the outer wall 1 and the base plate 9 of the roof 2 of the lower house. At the tip of the eaves of the field board 9, an eaves draining board 11 having a substantially inverted L-shaped cross section is attached. On the wall between the outer wall 1 and the roof 2 of the lower house,
The above-mentioned drainage sheet A for underwater is arranged on the water lower end side near the wall, one side piece 3 is brought into contact with the base 8 via the roof base sheet 10, and the other side piece 4 is connected via the roof base sheet 10. And is abutted on the field board 9. At this time, the release paper 7 is peeled off and the adhesive layer 6 is applied. In addition, a wall drainer sheet B having an L-shaped cross section is laid so as to extend from the ridge of the roof 2 of the lower house to the drainer sheet A for water drainage between the outer wall 1 and the roof 2 of the lower house. One side piece and the other side piece of the sheet B are in contact with the base 8 and the square plate 9 via the roof base sheet 10. The water draining sheet B near the wall is also made of synthetic resin, rubber or the like (including a thin metal plate inserted), and a plurality of drainage fins 12 are provided in a protruding manner. An end portion of the water draining sheet B near the wall on the underwater side is superposed on the underwater draining sheet A. The ridge part near the wall is disposed so as to straddle the ridge part drainer sheet C having an L-shaped cross section, and the ridge part drainer sheet C is superposed on the water-side end of the wall-side drainer sheet B. On the roof base sheet 10 of the roof 2 of the lower house, a roof tile 13 such as a flat tile is roofed. At this time, the roof tile 13 is also roofed on the underwater drainage sheet A, the wall edge drainage sheet B, and the ridge drainage sheet C. Also, when the roof tile 13 is being roofed, the roof tile 13a for starter is roofed at the tip of the eaves, and the roof tile 13a for starter and the ordinary roof tile 13 are piled up at the tip of the eaves. A triangular cutout 14 is provided at a corner of the roof tile 13a on the underwater side near the wall, and the cutout 14 and the drainage projection 5 of the underwater drainage sheet A are made to correspond to each other. A drainage gap 15 is formed between the edge and the edge of the notch 14. Further, after roofing the roof tile 13, a wall draining plate 16 having an L-shaped cross section is attached along the wall between the roof tile 13 and the outer wall 1. An exterior material 17 is attached to the outer surface of the outer wall 1.

The outer wall 1 and the roof 2 of the lower house are constructed as described above, and the rainwater that has fallen on the roof 2 of the lower house flows along the roof slope on the roof tile 13 and the rainwater that has fallen on the exterior material 17 is the exterior material 17. Along the wall tiles 16 to the roof tiles 13, and then falls from the wall tiles 16 to the roof tiles 13 and flows along the roof tiles 13. At this time, water may infiltrate from the space between the wall draining board 16 and the roof tile 13 to the ground side of the wall, but even if water enters the ground side, the ridge drainer sheet C, the wall drainer sheet B and the submerged water It is received by the drainage sheet A, flows downward along these lines, and is drained from the eaves of the roof 2 of the lower house. When water flows through the underwater draining sheet A, since there is a draining protrusion 5, a drainage gap 15 between the draining protrusion 5 and the notch 14 edge of the starter roof tile 13a is formed as shown in FIG. The water flows through the outer wall 1 while being guided so that the water does not go to the outer wall 1 side, and the water does not enter the outer wall 1.

Further, since one side piece 3 and the other side piece 4 of the drainage sheet A for underwater use have draining protrusions 5, even if one side piece 3 is stacked on the roof 2 of the lower house, the other side piece 4 is moved to the lower house. Even if it is piled up on the roof 2 of the above, there is a draining protrusion 5 on the underwater side, so that it can be used by both the lower water end on the left side and the lower water end on the right side of the roof 2 of the lower house.

[Advantages of the Invention] As described above, the present invention provides a right-sided triangular draining protrusion having a predetermined thickness symmetrically adjacent to the water lower end of one side piece and the other side piece of the underwater drainage sheet, and The above-mentioned underwater draining sheet is arranged on the underwater side of the wall between the outer wall and the roof of the lower house, and one side piece of the underwater draining sheet is brought into contact with the outer wall and the other side piece is moved to the lower house. Since it is laid so that it touches the roof of the lower house, the drainer protrusion is located on the water side of the side piece laid on the roof of the lower house, and the water flowing along the drainer sheet for the underwater is applied to the outer wall side at the drainer protrusion. It prevents the water from flowing into the outer wall and prevents the outer wall from leaking due to the water draining protrusion, and which side piece is one of the two side pieces of the draining sheet for draining water. Even if you lay it on the roof of the lower house, there is a draining protrusion on the underside of the lower house. The same drainage sheet for underwater can be used for both undersides on the left and right of the root to reduce the number of parts, and one side piece of the drainage sheet for underwater contacts the outer wall. With the other side piece laid so as to contact the roof of the lower house, for the starter on the underwater side of the roof tile that is roofed on the roof of the lower house, place the roof tile on the draining sheet for the underwater and for the starter The drainage projection of the drainage sheet for underwater was located in the triangular cutout provided at the corner on the underwater side of the roof tile wall, and a drainage gap was formed between the drainage projection and the cutout edge. Therefore, even if there is a right-angled triangular draining protrusion on the underside of the draining sheet for drainage, it is only necessary to provide a triangular notch at the corner on the wall side of the starter roof tile. The roof tile for the starter can be thatched so that it does not get in the way. Ri, moreover drainage gap inclined to away gradually from the outer wall toward the Underwater side between the cutout edge and draining projection of roof tiles for the starter is formed,
The drainage gap allows smooth drainage.
