Description

  The present invention relates to a draining member and a draining structure of an outer wall.

BACKGROUND ART Conventionally, a ventilation path is formed between a wall skeleton and an outer wall material on an outer wall to protect the wall skeleton and the outer wall material from corrosion due to moisture and dew. On the other hand, in a wall frame having an arched opening at the lower end, a parting member is attached so that the ventilation path is not exposed to the outside.
For example, in an outer wall having an opening serving as an entrance provided on the outer periphery of a building as described in Patent Literature 1, a lower end portion is connected to a wall frame formed in an arch shape and an end of the arch of the wall frame. And a wall frame. With these wall structures, an opening having a vertical straight side and an arched upper opening is formed. Further, an outer wall material is provided on the outer periphery of these wall frames so as to be separated from each other, and the separated gap serves as a ventilation path.
An arched parting material of the same shape is attached to the arched lower end of the wall frame and the outer wall material.
Specifically, the parting material abuts on the lower end surface of the wall skeleton, and the parting material is provided separately below the lower end of the outer wall material, and a sealing material is sometimes provided between the outer wall material and the parting material. The space is filled with a gap, and the gap is a ventilation port that communicates the ventilation path with the outside air.

Japanese Patent No. 5333465

However, in the ventilation structure of the wall body described in Patent Literature 1, for example, rainwater attached to the outer wall material during rainy weather propagates to the lower end portion of the outer wall material and stays at the lower end portion due to surface tension. And since a lower end part is formed in the shape of an arch, it flows along the arch to the vertical opening side part formed in the outer wall.
For this reason, since rainwater flows intensively through the opening side, the opening side is contaminated with water scale or the like due to rainwater.
Therefore, the appearance of the outer wall formed by the wall skeleton and the outer wall material impairs the aesthetic appearance, and particularly when the opening is an entrance of a building, it is easy for human eyes to notice, and the influence of the contamination becomes extremely high. There is a problem.
Also, since rainwater flows intensively to the opening side, the opening side is exposed to more rainwater than other locations.
In particular, when water is applied to the connection between the wall skeleton having the arch-shaped lower end and the wall skeleton connected to the end of the arch, the skeleton structure of the outer wall is affected.
For this reason, there is also a problem that the aging deterioration such as corrosion due to rainwater at the connection portion becomes more severe than at other portions.

  The present invention has been made in view of the above-described problems, and secures a ventilation path, and does not expose the ventilation path to the outside, does not stain the opening, maintains the aesthetic appearance of the building, and reduces the aging of the outer wall. It is an object of the present invention to provide a water draining member and a water draining structure for an outer wall.

In addition, it can also be adopted when the support parts 5 on both sides of the arch part 32 are wall frames (wall-wall).

[How to attach the drainer]
Next, a method of attaching the drainer 4 to the wall body 7 will be described.
As shown in FIGS. 8 to 11, first, the outer wall waterproof sheet B is attached to the support 5 near both ends of the arch portion 32, and a drainer 45 is disposed along the wall frame 7 or the support 5 from outside. . In addition, the waste water drainer 45 may be formed by combining a plurality of plate members.
Thereafter, the draining member 4 is configured such that the main body portion 41 abuts against the arch portion 32 of the wall frame 7, the inner surfaces of the pair of mounting portions 43 abut on both surfaces of the wall surface of the wall frame 7, respectively, and the contact between the wall surface and the mounting portion 43. At the contact surface, for example, a screw is screwed into the wall body 7 to be attached to the wall body 7. Then, the waterproof sheet A is attached across the mounting portion 43 and the wall surface so as to cover the screw head of the screw screwed into the wall frame 7.
Further, both ends of the longitudinal direction end of the draining member 4 are not provided to both ends of the arch portion 32, respectively, and both ends of the arch portion 32 and the draining member 4 are provided separately. That is, the outer surface of the water return 44 does not come into contact with the wall skeleton 7 or the support 5 at both ends of the arch portion 32, and is arranged separately.

Next, as shown in FIG. 11, an outer wall waterproof / moisture permeable sheet B continuous from the upper wall surface of the waterproof sheet A is attached to the wall frame 7, the support 5, and the mounting portion 43. A plurality of spacers S are appropriately attached to the outside. By attaching the outer wall material 6 from the outside of these spacers S, the wall surface of the wall frame 7 and the outer wall material 6 are separated by the thickness dimension of the spacer S. In the water return 44, a folded portion 441 b having a width substantially equal to the thickness of the spacer S is sandwiched between the wall surface and the inner surface of the outer wall material 6, and the vertical portion 441 a protrudes from the outer surface of the outer wall material 6.
The space between the wall surface of the wall body 7 and the outer wall material 6 separated by the spacer S becomes a ventilation path V for preventing corrosion of the wall body 7, the support 5 and the outer wall material 6.
As shown in FIG. 10, the lower end of the outer wall member 6 and the protruding portion 42 are provided separately, and the separated gap serves as a ventilation port between the ventilation path V and the outside air. In addition, the size of the spacer S may be large or small, and may be appropriately adjusted so that the ventilation state of the ventilation path V is good.

[Function of the draining structure of the outer wall]
Next, the operation of the draining of the draining structure of the outer wall will be described.
When rain falls on the building 2 in which the drainage structure 1 of the outer wall 3 is adopted, the rainwater adheres to the outer wall material 6 and the rainwater travels downward along the outer wall material 6. In this case, the rainwater adhering to the outer wall material 6 above the arch portion 32 is transmitted to the arch portion 32. This rainwater is transmitted to the side of the arch portion 32 along the arch portion 32, or raindrops flowing down from the arch portion 32 adhere to the lower projecting portion 42, and follow the arch shape of the projecting portion 42. It travels to the side of the protrusion 42.
Then, the rainwater transmitted to the side of the projecting portion 42 is stopped by the rising portions 441 of the water return 44 provided at both ends of the long end of the draining member 4, and the wall frame 7 and the projecting portion are stopped. It flows out of the wall surrounded by the space 42 and the water return 44.
In addition, the main body 41 and the protruding portion 42 are not extended to both ends in the longitudinal direction of the arch portion 32, and the wall frame 7 and the main body 41 are provided separately at both ends. When the water whose flow has been stopped flows out, it falls to the ground without adhering to the wall frame 7 or the support 5.
Further, since the folded portion 441b is provided at the upper end of the vertical portion 441a, for example, when the amount of rainfall is large, the rainwater vigorously hits the water return 44, and the folded portion 441b does not get over the vertical portion 441a. It is designed to stop the flow. Further, when the rainwater vigorously hits the water return 44, the rainwater splashed in the ventilation path V is prevented from adhering to the wall frame 7 by the water stop plate 443.

Also, the rainwater that has entered the gap between the outer wall member 6 and the protrusion 42 is transmitted to the side of the protrusion 42 along the upper surface of the protrusion 42. In addition, since the upper surface of the projection 42 is an inclined surface that descends toward the outside of the wall surface, the rainwater travels along the upper surface of the projection 42 to the side of the projection 42 and extends along the inclined surface. I will go to the direction.
The rainwater adhering to the side surface of the protruding portion 42 is transmitted to the side of the protruding portion 42 along the vicinity of the lower surface of the protruding portion 42, and the flow is stopped by the hanging portion 442 of the water return 44. It flows down along the inner surface of 442.
In this case, since the hanging portion 442 is hanging toward the center of the opening 31, rainwater is more reliably prevented from adhering to the wall frame 7 or the support 5.

As described above, in the present embodiment, for example, as shown in FIGS. 2 and 8-10, the wall frame 7 having the arch-shaped arch portion 32 at the lower end portion and the wall frame 7 are separately provided on the wall surface of the wall frame 7. A draining structure 1 of the outer wall 3 including an outer wall material 6 having an arch-shaped arch portion 32 at a lower end portion thereof and a draining member 4 attached to the arch portion 32, wherein the draining member 4 includes the arch portion. 32, and a water return 44 provided at a longitudinal end of the main body 41. The main body 41 extends to both ends of the arch 32. It is not provided, the both ends are separated from the wall frame 7, the main body 41 is separated from the lower end of the outer wall material 6, and the water return 44 is separated from the elongate end of the main body 41. Since it has a rising part 441 that rises For example, rainwater attached to the outer wall material 6 during rainy weather is transmitted to the side of the arch portion 32 along the arch portion 32 at the lower end of the outer wall material 6 and attached to the gap between the outer wall material 6 and the protrusion 42. The rainwater travels along the arch 32 of the main body 41 to the side of the arch 32.
The rainwater transmitted to the side of the arch portion 32 is stopped by the water return 44 and flows out of the wall surrounded by the wall frame 7, the main body 41, and the water return 44. .
Further, since the main body 41 is not extended to both ends of the arch portion 32 and both ends are separated from the connecting portion J between the side portion of the opening 31 and the upper portion, the main body portion 41 flows out of the above-described wall surface. Rainwater does not adhere to the connection portion J or the side of the opening 31.
For this reason, the side portion of the opening 31 and the connecting portion J are not contaminated by water scale or the like due to rainwater, and the appearance of the outer wall 3 formed by the wall skeleton 7 and the outer wall material 6 is not likely to impair the aesthetic appearance. The beauty of No. 3 can be maintained.
In particular, when the opening 31 of the outer wall 3 is an entrance of the building 2, the effect of maintaining the aesthetic appearance of the building 2 by eliminating the possibility of contamination can be significantly enhanced because the opening 31 is easily accessible to the public.
Further, since the flow of rainwater is stopped by the water return 44 separated from the connection portion J, rainwater does not adhere to the connection portion J and the side portion of the opening 31. In particular, when water is immersed from the connection portion J, the skeleton structure of the outer wall is affected, but the portion is not exposed to more rainwater than other portions.
For this reason, there is no possibility that the deterioration of the connecting portion J and the side portion of the opening 31 over time such as corrosion due to rainwater will be more severe than at other portions.

In the present embodiment, for example, as shown in FIGS. 2-5 and 9, since the water return 44 has a shape along the shape of the wall skeleton 7 to be attached, when the water return 44 is attached to the wall skeleton 7. In order to attach the water return 44, it is only necessary to cut out the outer wall material 6 in accordance with the shape of the water return 44, and it is not necessary to change the shape of the wall frame 7, and the water return 44 can be easily attached.
For this reason, the drainer 4 can be easily attached to the outer wall 3.

  In the present embodiment, the water draining member 4 is in contact with the wall surface of the wall body 7 at the outdoor long end of the main body 41, and is provided integrally with the mounting portion 43 and the water return 44. Since the plate 443 is provided, for example, when there is a large amount of rain such as heavy rain or a typhoon, a large amount of rain water is transmitted to the side of the arch portion 32, and the rain water vigorously hits the water return 44, and the rain water splashed in the ventilation path V is a wall. The water stop plate 443 can prevent the water blocking plate 443 from adhering to the frame 7.

Further, in the present embodiment, since the water return 44 is provided with the hanging portion 442 that hangs downward from the main body portion 41, the rainwater attached to the main body portion 41 follows the arch shape of the lower end portion of the main body portion 41. As a result, the water flows down to the side of the arch portion 32, the flow is stopped by the hanging portion 442, and the water flows down along the hanging portion 442.
For this reason, the rainwater attached to the main body 41 can flow downward from the hanging part 442.
Therefore, the side portion of the opening 31 and the connecting portion J are not contaminated by water scale or the like due to rainwater, and the appearance of the outer wall 3 formed by the wall frame 7 and the outer wall material 6 is not likely to impair the aesthetic appearance. You can maintain the aesthetics.
Further, since the hanging portion 442 is provided, for example, when dew condensation freezes in the vicinity of the hanging portion 442 in winter, the outer wall 3 is not directly damaged by frost.

Further, in the present embodiment, since the main body portion 41 includes the mounting portion 43 which is a rising portion that comes into contact with the wall surface along the longitudinal direction, the main body portion 41 is provided outside the wall frame 7 in the gap between the outer wall material 6 and the main body portion 41. Since the attachment portion 43 is located, the seam between the main body portion 41 and the wall frame 7 is not exposed to the gap.
Therefore, there is no possibility that the infiltrated rainwater infiltrates between the main body portion 41 and the wall frame 7, and the wall frame 7 can be more reliably protected from corrosion.

  Further, in the present embodiment, since the main body 41 and the mounting portion 43 are integrally formed without a seam, the seam between the main body 41 and the mounting portion 43 is not exposed to the gap, and the infiltrated rainwater There is no risk of infiltration between the main body portion 41 and the mounting portion 43, and the wall frame 7 can be more reliably protected from corrosion.

Further, in the present embodiment, a protruding portion 42 that protrudes below the outer wall material 6 from an edge along the longitudinal direction of the main body portion 41 is provided, and an upper surface of the protruding portion 42 has an inclined surface that goes down in the protruding direction. Because of this, the rainwater that has entered the gap between the outer wall material 6 and the protrusion 42 can be transmitted outward due to the inclination of the upper surface of the protrusion 42.
For this reason, the rainwater that has entered the gap does not remain on the upper surface of the protruding portion 42, and the ventilation path V can be kept dry when the weather is fine, and the wall frame 7 and the outer wall material 6 are reliably protected from corrosion. be able to.
Therefore, for example, there is no need to arbitrarily restrict the flow between the ventilation passage V and the outside air by filling a part of the gap between the outer wall material 6 and the protruding portion 42 with a sealing material. Thus, the wall frame 7 and the outer wall material 6 can be protected from corrosion.

In the present embodiment, for example, as shown in FIGS. 2 and 3-9, the water return 44 is provided with a folded portion 441b that rises toward the center of the arch at the upper end of the vertical portion 441a. .
By doing so, for example, when there is a large amount of rainfall due to a typhoon or the like, there is no possibility that the rainwater flowing to the water return 44 will flow over the vertical portion 441a and flow to the wall frame 7 or the support 5. The turn-back portion 441b can stop the flow even if the rainwater has the strength to get over the vertical portion 441a.

Further, in the present embodiment, before attaching the main body 41 to the arch 32, the drainer 45 is disposed along the wall frame 7 or the support 5 near both ends of the arch 32.
By doing so, the waterproof property can be further enhanced at both ends of the arch portion 32, that is, at the side portions of the opening 31, and protection from corrosion due to water intrusion can be achieved.

Further, in the present embodiment, the height of the attachment portion 43 provided outside the building 2 is higher than that provided inside the building 2.
By doing so, more rainwater adheres to the outside of the building 2 than to the inside. In other words, more rainwater flows to the side of the opening 31 on the outside than on the inside. Since the height of the mounting portion 43 is higher on the outside than on the inside, it is possible to prevent water from entering the wall frame 7 over the mounting portion 43.
Further, for example, in a case where the wind is strong such as a typhoon and exposed to rain such as a lateral strike, there is a possibility that raindrops may jump vigorously into a gap between the outer wall material 6 and the protrusion 42. However, since the height dimension of the mounting portion 43 is formed large, there is no possibility that raindrops may enter the wall frame 7.

As described above, the present invention has been specifically described based on the present embodiment. However, the present invention is not limited to the above embodiment, and can be changed without departing from the gist of the present invention.
In the present embodiment, the draining structure 1 of the outer wall 3 is adopted as a column-post, wall-post, and column-wall variation, but is not limited thereto, and may be adopted in a wall-wall pattern.

Further, in the present embodiment, the upper edge of the opening 31 is the arch portion 32 having an arch shape, but is not limited thereto. For example, the shape may be such that one end of the opening 31 is linearly inclined toward the other end as the uppermost portion, and the substantially central portion of the opening 31 is linearly inclined toward the opposite ends as the uppermost portion. It may be something.
Furthermore, a shape obtained by combining a plurality of arcs, such as a three-leaf clover, may be employed, and not only the upper edge of the opening 31 but also substantially the entire opening 31 may be formed in an arc shape.
