Description

  In the present invention, a thin plate-like roof material (for example, a slate or asphalt single) is used for a roof keraba portion (the end portion on the side of the gable roof) or a wall joint portion (the wall and the roof material are in contact with each other). (Part) regarding draining.

  Draining the keraba and wall joints between the roof material and the field board without causing the rainwater that flows from the side of the roof material of the keraba part or wall joints to penetrate the field board due to storms or heavy rain. It is for receiving and guiding to the eaves and draining.

  As a conventional drainer, in a front view (sectional view from the eaves side), an outer vertical portion extending vertically, an outer horizontal portion extending horizontally from the upper end of the outer vertical portion, and downward from the tip of the outer horizontal portion An intermediate vertical portion extending vertically, an intermediate horizontal portion extending horizontally from the lower end of the intermediate vertical portion toward the outer vertical portion, an inner vertical portion extending vertically downward from the tip of the intermediate horizontal portion, and an inner vertical portion A drainer having an inner horizontal portion extending horizontally from the lower end of the inner side in the opposite direction to the outer vertical portion and a folded portion folded upward at the tip of the inner horizontal portion is connected to the inner vertical portion and the inner horizontal portion A vertical support that extends vertically downward, and a horizontal support that extends horizontally from the lower end of the vertical support in the opposite direction to the outer vertical so as to be placed in parallel with a certain distance below the inner horizontal And the folded back upward at the tip of the horizontal support It is provided with a draining sheet having a support portion (e.g., see Patent Document 1).

  In the conventional drainer, the inner horizontal part and the drainer sheet are inserted between the roofing sheet and the groundboard covered with waterproof paper in the keraba part, and the inner vertical part is placed facing the side of the roofing part. It was constructed in support of the lower surface of the roofing material.

  In addition, there are those provided with a sealant material on the folding support part side on the horizontal support part of the draining sheet and those provided with a sealant material on the folding part of the inner horizontal part although the draining sheet is not provided. (For example, refer to Patent Document 1).

  Usually, rainwater that has flowed from the gap between the side of the roofing material and the inner vertical part due to storms or heavy rains, etc., travels along the inner vertical part and falls onto the inner horizontal part, and is guided to the inner horizontal part as it is and flows down to the eaves. It will be drained.

  However, dust or sand that has entered through the gap between the side surface of the roofing material and the inner vertical part accumulates on the inner horizontal part for many years. Rainwater that flows from the gap and travels along the inner vertical part and falls onto the inner horizontal part is blocked and collected, and eventually the rainwater overflows beyond the folded part without being guided toward the eaves, and the roof There was a case where the field board rots through the nails that fix the material and penetrates into the field board.

  In the above-described conventional draining, even if rainwater overflows beyond the turned-up portion, the rainwater falls onto the horizontal support portion of the draining sheet and is guided to the eaves as it is and drained.

  Furthermore, since there is no gap between the folded portion or the folded support portion and the lower surface of the roof material due to the presence of the sealant material provided, rainwater may overflow beyond the folded portion or the folded support portion. There wasn't.

  However, the above-mentioned conventional drainer is provided with a sealant material in the inner horizontal part located under the roofing material, or a drainer sheet provided with a drainage sheet or sealant material in a position further below the inner horizontal part. Therefore, the height from the base plate to the roofing material is higher than the generally drained drainage, and the gap between the top and bottom of the base plate and the roofing material becomes large. There was a possibility that a tread crack by the worker (the roof material would break when the worker walks on the roof material during construction) sometimes occurred.

JP 2011-163094 A

  In the present invention, the dust and sand that have entered through the gap between the side surface of the roof material and the inner vertical portion for many years accumulate on the inner horizontal portion, and the side surface and the inner vertical surface of the roof material due to storms or heavy rain. Rainwater that flows in through the gap between the inner part and falls down along the inner vertical part is not dammed up and collected on the inner horizontal part. It is to provide a drainer whose height is not high.

  The first problem-solving means of the present invention includes at least a vertically extending inner vertical portion, an inner horizontal portion extending horizontally from a lower end of the inner vertical portion, and a folded portion folded upward at the tip of the inner horizontal portion. The inner horizontal part is inserted between the ground plate and the roofing material in the keraba part or the wall joint part, the inner vertical part is arranged to face the side surface of the roofing material, and the roofing material is A drainer for supporting the lower surface, characterized in that a groove extending from the ridge to the eave is provided in the inner vertical part.

  The second problem-solving means of the present invention includes an outer vertical portion extending vertically, an outer horizontal portion extending horizontally from the upper end of the outer vertical portion, and an intermediate vertical portion extending vertically downward from the tip of the outer horizontal portion. An intermediate horizontal portion extending horizontally from the lower end of the intermediate vertical portion toward the outer vertical portion, an inner vertical portion extending vertically downward from the tip of the intermediate horizontal portion, and an outer vertical portion extending from the lower end of the inner vertical portion It has an inner horizontal part that extends horizontally in the opposite direction, and a folded part that is folded upward at the tip of the inner horizontal part. The inner horizontal part is inserted between the field board and the roofing material in the keraba part, and the inner vertical part It is a drainer that supports the lower surface of the roofing material at the folded part, and has a groove extending in the direction from the ridge to the eaves. To do.

  The third problem-solving means of the present invention includes an outer horizontal portion extending horizontally, an inner vertical portion extending vertically downward from a tip of the outer horizontal portion, and a direction opposite to the outer horizontal portion from the lower end of the inner vertical portion. It has an inner horizontal part that extends horizontally and a folded part that is folded upward at the tip of the inner horizontal part. The inner horizontal part is inserted between the field board and the roofing material in the keraba part, and the inner vertical part is covered. It is a drainer that is placed facing the side of the material and supports the lower surface of the roofing material at the turn-up part, characterized in that a groove extending in the direction from the ridge to the eave is provided in the inner vertical part. is there.

  The fourth problem-solving means of the present invention includes an outer vertical portion extending vertically, an outer horizontal portion extending horizontally from the lower end of the outer vertical portion, and an inner vertical portion extending vertically downward from the tip of the outer horizontal portion. And an inner horizontal portion extending horizontally from the lower end of the inner vertical portion in a direction opposite to the outer vertical portion, and a folded portion folded upward at the tip of the inner horizontal portion, and the base plate and the roof in the wall joint portion An inner horizontal part is inserted between the two parts, and the inner vertical part is disposed so as to face the side of the roofing material, and the draining part supports the lower surface of the roofing material at the folded part. A groove extending in the direction is provided.

  A fifth problem solving means of the present invention is the draining of the first, second, third, or fourth problem solving means, wherein the opening of the groove is provided above the height of the folded portion. It is a feature.

  A sixth problem-solving means of the present invention is the draining of the first, second, third, fourth, or fifth problem-solving means, characterized in that the groove is composed of a concave-convex concave surface. To do.

  A seventh problem-solving means of the present invention is the draining of the first, second, third, fourth, or fifth problem-solving means, wherein the groove is composed of a concave portion in which a plurality of concave and convex portions are continuous. It is a feature.

  In the first, second, third, and fourth problem solving means of the present invention, the drainage of rainwater flowing in through the gap between the side surface of the roofing material and the inner vertical portion due to storm or heavy rain falls along the inner vertical portion. It can flow into a groove provided in the section extending from the ridge toward the eave, and can be guided to the eaves as it is and drained.

  For this reason, for example, even if dust or sand that has entered through the gap between the side of the roofing material and the inner vertical part accumulates on the inner horizontal part for many years, Rainwater that flows in through the gap between the inner part and the inner vertical part does not accumulate on the inner horizontal part.

  Therefore, since rainwater does not overflow beyond the turning part, rainwater does not spread through the nail that fixes the roofing material and permeates the field board under the waterproof paper, and the field board does not rot.

Further, the first, second, third, and fourth problem solving means of the present invention is drained by a sealant material provided on the inner horizontal portion located under the roofing material, or at a position further below the inner horizontal portion. Since a draining sheet or a draining sheet with a sealant material is not provided, the height from the field board to the roofing material is equivalent to the draining sheet that is generally distributed. The gap between the top and bottom is not increased.
For this reason, there is no possibility of tread cracking by the operator during construction.

  The draining of the fifth problem solving means of the present invention is because the opening of the groove is provided above the height of the folded portion, for example, from the gap between the side surface of the roofing material and the inner vertical portion over many years. Even if the dust, sand, or the like that has entered accumulates up to the height of the folded portion on the inner horizontal portion, the groove will not be filled with dust, sand, or the like.

  For this reason, rainwater that flows in through the gap between the side of the roofing material and the inner vertical part due to storms or heavy rain, etc., falls along the inner vertical part, flows into the groove without being disturbed by dust or sand, etc., and guides it directly to the eaves Can be drained.

  For example, even if a small amount of dust, sand, or the like falls in the groove, they do not accumulate, but are washed away by rainwater flowing through the groove and discharged at the eaves.

  In the draining of the sixth and seventh problem solving means of the present invention, since the groove is composed of a concave surface of a continuous uneven surface or a continuous concave portion of a plurality of uneven portions, from the ridge to the eave direction. A plurality of grooves extending in various shapes such as a straight line shape, a zigzag shape, and a staircase shape can be formed.

  For this reason, rainwater that flows through the gap between the side of the roofing material and the inner vertical part due to storms or heavy rain, etc., flows down the inner vertical part from various directions, is surely guided to the groove, and is guided to the eaves as it is, It can be drained.

  First, the drainer 10 of the keraba portion according to the first embodiment of the present invention will be described as follows (see FIG. 1).

  In the front view, the drainer 10 includes an outer vertical portion 12 extending vertically, an outer horizontal portion 14 extending horizontally from the upper end of the outer vertical portion 12, and an intermediate vertical extending vertically downward from the tip of the outer horizontal portion 14. Portion 16, intermediate horizontal portion 18 extending horizontally from the lower end of intermediate vertical portion 16 toward outer vertical portion 12, inner vertical portion 20 extending vertically downward from the tip of intermediate horizontal portion 18, and inner vertical portion The inner horizontal portion 22 extends horizontally from the lower end of 20 in the direction opposite to the outer vertical portion 12, and the folded portion 24 folded upward at the tip of the inner horizontal portion 22.

  The drainer 10 has an inner horizontal portion 22 inserted between a ground plate 26 laid with waterproof paper (not shown) in a keraba portion and a slate roof material 28, and the inner vertical portion 20 faces the side surface of the roof material 28. It is arranged and supports the lower surface of the roofing material 28 at the folding part 24, covers the climbing tree 30 with the outer vertical part 12 and the outer horizontal part 14 corresponding to the wind breaking part, and is constructed in the keraba part from the ridge to the eave. (See FIG. 2).

In general, the gap C between the inner vertical portion 20 and the side surface of the roof material 28 is 3 mm or less, and the gap S between the inner horizontal portion 22 and the lower surface of the roof material 28 is 2 mm or less. .
Further, the drainer 10 is inserted under a two-layered or three-layered portion of the roofing material 28.

Furthermore, the drainer 10 has the groove | channel 32 provided in the inner side vertical part 20 so that it might extend in the direction of an eave from a ridge when constructing in a keraba part (refer FIG. 1, 2).
The groove 32 is for guiding the rainwater R toward the eaves.

  For this reason, rainwater R that flows from the gap C between the side surface of the roofing material 28 and the inner vertical portion 20 due to a storm or heavy rain, and flows along the inner vertical portion 20 flows into the groove 32 and is guided to the eaves as it is. (See FIGS. 2 and 3).

  Therefore, for example, dust, sand, and the like D that have entered through the gap C between the side surface of the roofing material 28 and the inner vertical portion 20 have accumulated in the gap S between the inner horizontal portion 22 and the lower surface of the roofing material 28 over many years. However, only a small amount of rainwater R falling along the side surface of the roofing material 28 flows down on the inner horizontal portion 22, and the rainwater R falling along the inner vertical portion 20 hardly flows down on the inner horizontal portion 22. .

  For this reason, since rainwater R is blocked by the accumulated dust, sand, etc. D and does not accumulate on the inner horizontal portion 22 and overflow beyond the folded portion 24, the rainwater R fixes the roofing material 28. The nail plate 26 under the waterproof paper does not penetrate through the nail, and the wild plate 26 does not rot.

  Furthermore, the groove | channel 32 is provided so that the opening part 34 may become above the height H of the folding | turning part 24 (refer FIG. 1).

  For this reason, for example, dust, sand, or the like D that has entered through the gap C between the side surface of the roof material 28 and the inner vertical portion 20 over many years fills the gap S between the inner horizontal portion 22 and the lower surface of the roof material 28. Even if it accumulates so much, the groove | channel 32 is not buried with D, such as dust and sand.

  For this reason, the rainwater R that flows in through the gap C between the side surface of the roofing material 28 and the inner vertical portion 20 due to a storm or heavy rain and falls along the inner vertical portion 20 is not disturbed by the dust D, sand, or the like D, and is not disturbed. It will flow to the eaves and will be guided to the eaves as it is and drained.

  Normally, dust, sand, or the like D is a corner cut portion K of the lowermost roofing material 28 of the three-layered portion of the roofing material 28 in the gap S on the inner horizontal portion 22 when viewed from the windbreak portion side. It often accumulates in a portion (a portion where the upper corner of the roof material on the windbreak portion side is cut off obliquely so as not to block the rainwater that has flown in the spot) (see FIG. 4).

  This is because dust, sand, or the like D that has entered from the gap C between the side surface of the roofing material 28 and the inner vertical portion 20 little by little is caused to flow into the spot without being washed away by the rainwater R because the corner cut portion K becomes an obstacle. This is because they are dammed up.

  For example, even if a small amount of dust, sand, or the like D has fallen in the groove 32, since there is no obstacle such as the corner cut portion K in the groove 32, the dust, sand, etc. D accumulates in the groove 32. Instead, it is washed away by the rainwater R flowing through the groove 32 and discharged at the eaves.

  For this reason, the rainwater R flowing into the groove 32 is smoothly flowed from the building to the eaves without being disturbed by dust, sand, or the like D (see FIG. 4).

  The groove 32 is not limited to being provided such that the opening 34 is above the height H of the folded portion 24.

  In addition, when a drainer having a groove 32 provided so that the upper part of the opening 34 is higher than the uppermost surface of the roofing material 28 is inserted under the two-layered portion of the roofing material 28, the opening The rainwater R that has flowed from the gap G between the upper portion 34 and the side surface of the roofing material 28 flows directly into the groove 32 without flowing down on the inner horizontal portion 22, and is directly guided to the eaves and drained ( (See FIG. 5).

  Further, the groove 32 has a substantially inverted U shape that is recessed toward the outer vertical portion 12 in the inner vertical portion 20 in a front view, but is not limited thereto, and is recessed toward the outer vertical portion 12 side. Any shape can be used, and any shape can be used as long as it has a function as a groove.

  For example, it may have a shape such as a substantially square-shaped groove 36 (see FIG. 6A) or a substantially square-shaped groove 38 (see FIG. 6B).

  In addition, a groove 40 (see FIG. 7 (a)) whose lower portion is continuous with the inner horizontal portion 22 at the lower end of the inner vertical portion 20, and a recess whose upper portion is continuous with the intermediate horizontal portion 18 at the upper end of the inner vertical portion 20. A groove 42 (see FIG. 7B), or a sealant material 44 attached to the lower end of the inner vertical portion 20 to form a recess whose upper portion is continuous with the intermediate horizontal portion 18 at the upper end of the inner vertical portion 20. The shape may be a groove 46 (see FIG. 8A).

  In addition, the concave and convex surface 50 of the concave and convex surface 48 extending in the vertical direction extending from the ridge to the eave may be a groove 52 (see FIG. 8B) or a groove 54 (see FIG. 9A).

  In addition, a continuous recess 58 extending from the ridge to the eave in the plurality of uneven portions 56 arranged in a grid pattern is a groove 60 (see FIGS. 9B and 10A), or a staggered pattern. A continuous recess 64 extending from the ridge to the eave in the plurality of uneven portions 62 arranged in a lattice shape may be a groove 66 (see FIG. 10B).

  In addition, a mesh 70 having a mesh 68 that is thicker in the lateral direction than the longitudinal direction is attached to the inner vertical portion 20, and a plurality of meshes 68 are formed as uneven portions 72 in the front view, and the longitudinal direction of the mesh 68 is The recess 74 may be a groove 76 that is continuous from the ridge to the eaves (see FIGS. 11A and 11B).

  In addition, a sheet material 80 having a plurality of concave and convex portions 78 is attached to the inner vertical portion 20 with the concave and convex portion 78 side facing the inner vertical portion 20, and a concave portion 82 continuous from the ridge to the eave is formed in the groove 84. (See FIGS. 12 (a) and 12 (b)).

  When the above groove is composed of a concave / convex surface of a continuous concavo-convex surface or a continuous concave portion of a plurality of concavo-convex portions, various shapes such as a linear shape, a zigzag shape, and a staircase shape from the ridge to the eave A plurality of grooves extending in the direction can be formed, so that rainwater R that flows in from the gap C between the side surface of the roofing material 28 and the inner vertical portion 20 due to storms or heavy rain, etc., travels along the inner vertical portion 20 from various directions. It is possible to reliably lead to the groove.

Further, the groove 32 may be provided with a projection 86 provided at the top toward the bottom, such as a rounded tip or a sharp tip (see FIGS. 13A and 13B). .
Note that the shape of the protrusion 86 is not limited.

  By providing the projection 86 on the upper portion of the groove 32, rainwater R that flows in from the gap C between the side surface of the roofing material 28 and the inner vertical portion 20 due to a storm, heavy rain, etc., and falls along the inner vertical portion 20 is collected in the projection 86. Since it can be transmitted and dropped to the bottom of the groove 32, the rainwater R can be easily collected in the groove 32.

  Next, the drainer 88 of the keraba portion according to the second embodiment of the present invention will be described as follows (see FIG. 14).

  The drainer 88 is, when viewed from the front, the outer horizontal portion 14 that extends horizontally, the inner vertical portion 20 that extends vertically downward from the tip of the outer horizontal portion 14, and the direction from the ridge provided in the inner vertical portion 20 to the eaves.
