Description

【0001】
【発明の属する技術分野】
本発明は、建物の壁面に対してほぼ直交する方向に貫通して配置される排水管を備えた排水具に取り付けられる付属具および当該排水具に関するものである。
【0002】
【従来の技術】
本願発明者は、図7に示すように、ベランダ等の陸屋根の床面Xと外壁Yとが交叉するコーナ部に設置される排水具2を提案している(例えば、特許文献1参照。)。この排水具2は、排水管7を備えたもので、この排水管7を外壁Yに設けた貫通孔Zに挿嵌して、この排水管7の先端の排水口6を外壁Yの外側に配置した状態で設置される。
【0003】
【特許文献1】
特開平2002−38665号公報
【0004】
【発明が解決しようとする課題】
しかしながら、上記の排水具2は、排水管7を単に径方向に切断して排水口6が設けられていることから、その排水口6から流下する排水の水切れが悪く、図7に示すように、水滴Wが排水口6から排水管7の下面側に回り込みやすい。そして、排水管7の下面側に回り込んだ水滴Wは、風等の影響を受けても滴下せず、排水管7の下面側をつたって建物の外壁Y側に移動して、排水管7と外壁Yとの隙間に浸入し、外壁Yや建物内部に使用されている木材等の建材を腐らせ、変色や雨漏りを発生させ、建物の寿命を短かくしてしまう。
【0005】
本発明は、上記問題点に鑑みて提案されたものであって、排水の水滴が建物内に浸入するのを効果的に防止できる排水具用付属具および排水具を提供することを目的とするものである。
【0006】
【課題を解決するための手段】
以上の目的を達成するために、請求項1記載の発明の排水具用付属具は、
建物の壁面に対してほぼ直交する方向に貫通して配置される排水管を備えた排水具に取り付けられる付属具であって、排水が排水管の下面をつたって建物側に流れるのを阻止する阻止部を備えていることを特徴とするものである。
また、請求項2記載の発明の排水具は、建物の壁面に対してほぼ直交する方向に貫通して配置される排水管を備えた排水具であって、排水が排水管の下面をつたって建物側に流れるのを阻止する阻止部が、排水管に一体形成されていることを特徴とするものである。
【0007】
【発明の実施の形態】
以下に、請求項1に係る発明の第1の実施の形態について、詳細に説明する。
【0008】
本実施形態の排水具用付属具1aは、図1に示すように、建物の壁面に対してほぼ直交する方向に貫通して配置される既設の排水具2に取り付けられるものである。
【0009】
排水具2は、例えばポリエステル樹脂とガラス繊維とから成るFRPで成型されており、図2に示すように、ベランダの床面X上に配置される床面当接部3と、床面当接部3の前縁から直立し、外壁Yのベランダ側の面に配置される壁面当接部4と、壁面当接部4に連設される排水管7を備えている。
排水管7は、壁面当接部4側に集水口5を有するとともに、遊端部側に排水口6を備えている。また、排水管7およびこの排水管7内の排水路71は、集水口5側から排水口6側に向かって、やや先細に形成されている。
排水具2は、図2に示すように、ベランダ等の陸屋根の床面Xと外壁Yとが交叉するコーナ部に設置される。つまり、排水具2は、コーナ部の外壁Yにあらかじめ設けられた貫通孔Zに排水管7を挿嵌して、排水管7の先端の排水口6を外壁Yの外側に配置し、床面当接部3を床面Xに、壁面当接部4を外壁Yのベランダ側の面にそれぞれ当接させた状態で固定される。
【0010】
排水具用付属具1aは、排水具2と同じ材質で成型されており、図3に示すように、排水管7における排水口6側の開口端の外径よりも1回り大径で、排水管7の排水口6に嵌合可能な筒部8と、筒部8に一体に形成された阻止部9とを備えている。阻止部9は、図1,図3に示すように、先細の舌片状で、筒部8の一端開口側の開口端部から斜め下方に向かって延設されている。
【0011】
排水具用付属具1aは、上記のように、ベランダ等の陸屋根のコーナ部に設置された排水具2の先端部分に一体に取り付けられる。具体的には、阻止部9を排水管7の下方に配置した状態で、筒部8を排水口6側の外周面に嵌着させる。
【0012】
以上のように、本実施の形態の排水具用付属具1aは、先端部に阻止部9が形成されているので、排水管7内を通ってきた排水は、阻止部9をつたって流下するが、阻止部9は、排水管7の下方に配置されているため、阻止部9に残った水滴W2が、阻止部9の下面側に回り込むことがない。したがって、水滴W2が、排水管7の下面をつたって建物側に移動することがないので、水滴W2が、排水具2と外壁Yとの隙間に浸入して、雨漏りするとか、外壁や建物に使用されている木材等の建材を腐らせるなどの心配がなく、長期間快適に建物を使用することができる。
また、排水具用付属具1aは、既設の排水具2に後付けすることができるので、既設の排水具2を取り替える必要がなく、有効利用することができる。
さらに、工事が非常に容易で時間もかからないので、工事費を抑えることもできる。
【0013】
次に、本発明に係る排水具用付属具の第2の実施形態について説明する。
本実施形態の排水具用付属具1bは、図4に示すように、排水具2の外周面の一部に沿うように幅方向に湾曲させてなる湾曲部10と、湾曲部10の一端側の中央部分に形成された阻止部11と、阻止部11の両側に配置され、湾曲部10側に折り返すように形成される一対の係止部12,12とを備えたものである。阻止部11は、先細の舌片状で、湾曲部10の一端側から斜め下方に向かって延設されている。
【0014】
排水具用付属具1bを排水具2に取り付ける際には、図4、図5に示すように、湾曲部10と係止部12,12とで、排水管7の排水口6側における開口端部を挟持する。
【0015】
排水具用付属具1bによれば、排水管7の排水口6側における開口端部の一部を挟持するものであるので、ワンタッチで簡単に取り付けることができる。また、排水具用付属具1bは可撓性を有しているので、湾曲部10に多少寸法誤差がある場合でも、湾曲部10のたわみを利用して排水管7に取り付けることができる。
【0016】
次に、請求項2にかかる排水具の実施の形態について説明する。本実施形態の排水具2bは、ポリエステル樹脂とガラス繊維とから成るFRPで成型されたものであり、図6に示すように、排水口6の下端部分に斜め下方に向かって、先細の舌片状に形成された阻止部13が延設されている。
【0017】
排水具2bは、阻止部13を一体に備えているので、排水管7と阻止部13との連続部分に段差がなく、雨水やゴミなどが溜まりにくい。
【0018】
なお、上述した実施の形態においては、排水管7の形状を丸筒型としたが、排水管7の形状はこれに限定されず、例えば角筒型でもよい。なお、角筒型の場合は、排水具用付属具1aの筒部8、および排水具用付属具1bの湾曲部10の形状を何れも角筒形状に沿う形状に形成すればよい。
【0019】
また、排水具用付属具1aの筒部8は、排水管7の外周面に嵌着するものに限られず、筒部8の外径を排水管7における排水口6側の開口端の内径よりも1回り小径に形成して、排水管7の内周面に嵌着してもよい。
【0020】
また、排水具用付属具1a,1bおよび排水具2,排水具2bの材質は、FRPに限られず、耐候性を有する合成樹脂製であってもよいし、さらに金属製であってもよい。
【0021】
【発明の効果】
本発明の排水具用付属具は、建物の壁面に対してほぼ直交する方向に貫通して配置される排水管を備えた排水具に取り付けられる付属具であって、排水が排水管の下面をつたって建物側に流れるのを阻止する阻止部を備えているので、
排水管内を通ってきた雨水等の排水が、排水管の下面側に回り込んで排水管の下面をつたって建物の壁面に移動するのを効果的に阻止することができる。したがって、排水の水滴が、排水管と外壁との隙間に浸入して、雨漏りを引き起こすとか、外壁や建物に使用されている木材等の建材を腐らせるなどの心配がなく、長期間快適に建物を使用することができる。また、排水具用付属具は、既設の排水具に後付けすることができるので、既設の排水具を有効利用することができる。
【0022】
また、請求項2に記載の排水具は、建物の壁面に対してほぼ直交する方向に貫通して配置される排水管を備えた排水具であって、排水が排水管の下面をつたって建物側に流れるのを阻止する阻止部が、排水管に一体形成されているので、請求項1に記載の発明の効果に加えて、特に排水具を新規に設置する場合に適している。

An attachment attached to a drainage device having a drainage pipe penetrating in a direction substantially perpendicular to a wall surface of a building, the drainage stopping on a lower surface of the drainage pipe and flowing to a building side. It is characterized by having a blocking portion.
A drainage tool according to a second aspect of the present invention is a drainage tool provided with a drainage pipe penetrating in a direction substantially perpendicular to a wall surface of a building, wherein drainage is provided on a lower surface of the drainage pipe. The drainage pipe is provided with a blocking part for preventing the water from flowing toward the building.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the first embodiment of the invention according to claim 1 will be described in detail.
[0008]
As shown in FIG. 1, the drainage attachment 1a according to the present embodiment is attached to an existing drainage 2 that is disposed so as to penetrate in a direction substantially orthogonal to a wall surface of a building.
[0009]
The drainage tool 2 is formed of, for example, FRP made of polyester resin and glass fiber, and as shown in FIG. 2, a floor contact portion 3 arranged on the floor X of the veranda, and a floor contact The wall 3 includes a wall contact portion 4 that stands upright from the front edge of the portion 3 and is disposed on the veranda-side surface of the outer wall Y, and a drain pipe 7 that is connected to the wall contact 4.
The drain pipe 7 has the water collecting port 5 on the wall contact part 4 side and the drain port 6 on the free end side. The drain pipe 7 and the drain passage 71 in the drain pipe 7 are formed to be slightly tapered from the water collecting port 5 side to the drain port 6 side.
As shown in FIG. 2, the drainage device 2 is installed at a corner where a floor surface X of a flat roof such as a veranda and an outer wall Y intersect. That is, the drainage tool 2 is configured such that the drainage pipe 7 is inserted into the through-hole Z provided in advance in the outer wall Y of the corner portion, and the drainage port 6 at the tip of the drainage pipe 7 is disposed outside the outer wall Y. The contact portion 3 is fixed to the floor X, and the wall contact portion 4 is fixed to the veranda-side surface of the outer wall Y, respectively.
[0010]
The drainage attachment 1a is formed of the same material as the drainage 2 and, as shown in FIG. 3, has a diameter one size larger than the outer diameter of the open end of the drainage pipe 7 on the drain port 6 side. It has a tubular portion 8 that can be fitted to the drain port 6 of the pipe 7, and a blocking portion 9 formed integrally with the tubular portion 8. As shown in FIGS. 1 and 3, the blocking portion 9 has a tapered tongue shape, and extends obliquely downward from an opening end of the cylindrical portion 8 on one opening side.
[0011]
As described above, the drainage attachment 1a is integrally attached to the distal end of the drainage 2 installed at the corner of a flat roof such as a veranda. Specifically, the tubular portion 8 is fitted to the outer peripheral surface on the drain port 6 side with the blocking portion 9 disposed below the drain pipe 7.
[0012]
As described above, in the accessory for drainage device 1a of the present embodiment, since the blocking portion 9 is formed at the distal end, the drainage that has passed through the drain pipe 7 flows down through the blocking portion 9. However, since the blocking portion 9 is disposed below the drain pipe 7, the water droplet W <b> 2 remaining in the blocking portion 9 does not go to the lower surface side of the blocking portion 9. Therefore, since the water droplet W2 does not move to the building side along the lower surface of the drain pipe 7, the water droplet W2 enters the gap between the drainage tool 2 and the outer wall Y and leaks, or leaks into the outer wall or the building. The building can be used comfortably for a long time without worrying that the used building materials such as wood are rotten.
Further, since the drainage accessory 1a can be retrofitted to the existing drainage tool 2, the existing drainage tool 2 does not need to be replaced, and can be effectively used.
Furthermore, since the construction is very easy and takes less time, the construction cost can be reduced.

The blocking portion 11 has a tapered tongue shape and extends obliquely downward from one end of the curved portion 10.
[0014]
When attaching the drainage accessory 1b to the drainage tool 2, as shown in FIGS. 4 and 5, the curved portion 10 and the locking portions 12, 12 open the end of the drainage pipe 7 at the drain port 6 side. Hold the part.
[0015]
According to the accessory 1b for a drainage tool, since a part of the opening end on the drainage port 6 side of the drainage pipe 7 is sandwiched, it can be easily attached with one touch. In addition, since the drainage attachment 1b has flexibility, even if the bending portion 10 has some dimensional error, it can be attached to the drain pipe 7 by using the bending of the bending portion 10.
[0016]
Next, an embodiment of the drainage tool according to claim 2 will be described. The drainage tool 2b of the present embodiment is formed by FRP made of a polyester resin and glass fiber, and as shown in FIG. A blocking portion 13 formed in a shape extends.
[0017]
Since the drainage device 2b is provided with the blocking portion 13 integrally, there is no step in the continuous portion between the drainage pipe 7 and the blocking portion 13, and rainwater and dust are unlikely to accumulate.
[0018]
In the above-described embodiment, the shape of the drain pipe 7 is a round tube, but the shape of the drain pipe 7 is not limited to this, and may be, for example, a square tube. In the case of the rectangular tube type, the shape of the cylindrical portion 8 of the drainage accessory 1a and the shape of the curved portion 10 of the drainage accessory 1b may both be formed along the rectangular tube shape.
[0019]
In addition, the cylindrical portion 8 of the drainage accessory 1a is not limited to the one fitted to the outer peripheral surface of the drainage pipe 7; May be formed to have a small diameter, and may be fitted to the inner peripheral surface of the drain pipe 7.
[0020]
Further, the materials of the drainage attachments 1a and 1b and the drainage tools 2 and 2b are not limited to FRP, and may be made of a synthetic resin having weather resistance, or may be made of metal.
[0021]
【The invention's effect】
An accessory for a drainage device of the present invention is an accessory attached to a drainage device having a drainage pipe arranged to penetrate in a direction substantially perpendicular to a wall surface of a building, wherein drainage is provided on a lower surface of the drainage pipe. Since it has a blocking part that blocks it from flowing to the building side,
It is possible to effectively prevent the drainage of rainwater or the like that has passed through the drainpipe from flowing around the lower surface of the drainpipe and moving along the lower surface of the drainpipe to the wall surface of the building. Therefore, there is no worry that water droplets from drainage will enter the gap between the drain pipe and the outer wall and cause rain leakage, or the outer wall and the building materials such as wood used for the building will be rotten. Can be used. In addition, since the accessory for drainage can be retrofitted to the existing drainage, the existing drainage can be effectively used.
[0022]
