Description

この考案は、通気用あるいは配線・配管用に建物の壁面を貫通させて取付けるパイプに関する。 The present invention relates to a pipe which is attached by penetrating a wall of a building for ventilation or wiring and piping.

この種のパイプは通気用として、建物内の換気や有害な気体の排気に用いる。換気の場合は、パイプの屋外側に換気フードや換気扇を取付けることが多い。排気の場合は、通常、パイプの屋内側端にダクトが接続され、排気が発生元からダクトによりパイプまで誘導されてくる。配管・配線用の場合は、主として屋根裏や床下の隔壁部分に使用される。

In the case of ventilation, a ventilation hood or ventilation fan is often installed on the outdoor side of the pipe. In the case of exhaust, a duct is usually connected to the indoor end of the pipe, and the exhaust is guided from the source to the pipe by the duct. In the case of piping and wiring, it is mainly used for the attic and the partition wall under the floor.

特に、この種のパイプを通気用に使用するとき、屋外側からの雨水の侵入、パイプ内での結露の室内側への侵入を防ぐために屋外側をわずかに低く傾斜させて取付けている。しかし、パイプだけではパイプを傾斜させて固定するときの基準となるものがないので、壁に形成した貫通孔へパイプを通して、わずかな傾斜状態で適正に固定することが困難である。また、吸排気用に使用するときは、傾斜させたパイプの屋内側端にダクトを接続することが多いが、パイプとダクトの接続部を緊密にする必要からパイプの内端側外径とダクトの接続側内径がほぼ同じであり、ダクトをパイプへ接続しにくい。また、わずかに傾斜させて取付ける関係で、内端側の傾斜で切り口が上向いているため、接続のための差込み作業が困難となることが多い。
この考案は、壁に貫通させて取付ける傾斜パイプを屋内外方向に適正な角度をもって簡単に固定することができ、また、パイプの内端側にダクトを接続し易い構造の傾斜パイプを提供する。 In particular, when this type of pipe is used for ventilation, the outdoor side is mounted at a slightly lower slope in order to prevent rainwater from entering from the outdoor side and dew condensation inside the pipe from entering the indoor side. However, since there is no reference that can be used for fixing the pipe by inclining the pipe alone, it is difficult to properly fix the pipe in a slightly inclined state by passing the pipe through a through hole formed in the wall. In addition, when used for air intake and exhaust, a duct is often connected to the indoor end of the inclined pipe, but since the connection between the pipe and the duct needs to be tight, the outer diameter of the inner end of the pipe and the duct Are almost the same on the connection side, making it difficult to connect the duct to the pipe. In addition, since the cut end faces upward due to the inclination on the inner end side, the insertion work for connection often becomes difficult due to the slight inclination.
The present invention provides an inclined pipe which can easily fix an inclined pipe penetrating through a wall at an appropriate angle indoors and outdoors, and which can easily connect a duct to an inner end side of the pipe.

鍔と、これに貫通させるパイプ（筒体）で構成する。パイプは、その直径を外端側よりも内端側をわずかに小さく円錐状の一部として形成する。パイプの長さは壁の厚さよりも大きく壁の外側と内側の双方に突出する長さとしてある。鍔に対してパイプは、鍔の面を垂直にしたときパイプの側面視（パイプの長手軸方向を正面・背面方向とする）で下辺となる部分（以下、側面視下辺という）が外端側で低く内端側で高くなる配置で固定される。パイプの長手方向軸は、平面視で鍔の面に直交する場合と傾斜する場合がある。
鍔を壁面構成材に釘打ちなどで固定するとパイプは、自動的に設定した角度で外端側が低く内端側が高い傾斜状態で壁に固定される。 It is composed of a flange and a pipe (tubular body) penetrated therethrough. The pipe is formed as a part of a cone whose diameter is slightly smaller on the inner end side than on the outer end side. The length of the pipe is greater than the wall thickness and protrudes both outside and inside the wall. The outer side of the pipe is a lower side (hereinafter referred to as a lower side in side view) of the pipe when viewed from the side (the longitudinal axis of the pipe is defined as the front / back direction) when the surface of the pipe is perpendicular to the flange. And is fixed in an arrangement where it becomes lower on the inner end side. The longitudinal axis of the pipe may be perpendicular to the plane of the flange in plan view or may be inclined.
When the flange is fixed to the wall component by nailing or the like, the pipe is fixed to the wall at an automatically set angle with the outer end side lower and the inner end side higher.

このように、鍔を壁面構成材に固定するだけでパイプが設定した傾斜角度で壁へ簡単に固定される。また、パイプの内端側は径が小さく、わずかにテーパーとなっているので、ダクトを接続しやすく、また、パイプと緊密に接続することができる。 In this manner, the pipe is easily fixed to the wall at the set inclination angle only by fixing the flange to the wall surface component. Further, since the inner end side of the pipe has a small diameter and is slightly tapered, it is easy to connect the duct, and it is possible to tightly connect the pipe.

合成樹脂でパイプと鍔を一体成形する。パイプは外端側の径よりも内端側の径をわずかに小さくして円錐状とする。外端側の径と内端側の径との差は素材が合成樹脂の場合は、パイプの肉厚程度とする。また、側面視下辺の傾斜は水平面に対して０．５〜２．５°程度とする。側面視下辺に対向した側面視上辺は、パイプの前記外端側の径と内端側の径との差及び側面視下辺の傾斜の程度によって、鍔の垂直面に対して直交する状態となる場合や側面視下辺と同様に外端側が低くなる場合のほか、内端側が低くなる場合も生じる。 The pipe and flange are integrally formed with synthetic resin. The pipe has a conical shape with a slightly smaller diameter at the inner end than at the outer end. When the material is a synthetic resin, the difference between the diameter at the outer end and the diameter at the inner end is about the thickness of the pipe. In addition, the inclination of the lower side in the side view is about 0.5 to 2.5 ° with respect to the horizontal plane. The upper side in the side view facing the lower side in the side view is orthogonal to the vertical plane of the flange due to the difference between the diameter of the outer end side and the diameter of the inner end side of the pipe and the degree of inclination of the lower side in side view. In some cases, similarly to the lower side in the side view, the outer end is lower, and the inner end is lower.

図１〜３は第１の実施例である。円錐状傾斜パイプ１は、鍔２とパイプ３を備える。鍔２とパイプ３はこの実施例において、塩化ビニールの一体成形品であり、肉厚はどの部分も約２．５ｍｍである。この円錐状傾斜パイプ１は木造家屋の通気用であり、鍔２は一辺が２１１ｍｍの正方形、パイプ３は外端側の外径が１５５ｍｍ、内端側の外径が１５０ｍｍ、パイプ３の長さは２８７ｍｍである。
パイプ３は鍔２の面を垂直に配置したとき、パイプ３の側面視下辺が水平面と約１．４°の角度で交わるように外端側を低く内端側が高くなるように一体に固定される（図２）。このとき、この実施例ではパイプの側面視上辺は水平面と平行である。 1 to 3 show a first embodiment. The conical inclined pipe 1 includes a flange 2 and a pipe 3. In this embodiment, the flange 2 and the pipe 3 are integrally molded products of vinyl chloride, and each part has a thickness of about 2.5 mm. The conical inclined pipe 1 is for ventilation of a wooden house, the flange 2 is a square having a side of 211 mm, the pipe 3 has an outer diameter of 155 mm on the outer end side, an outer diameter of 150 mm on the inner end side, and the length of the pipe 3. Is 287 mm.
When the surface of the flange 2 is arranged vertically, the pipe 3 is integrally fixed so that the lower side in the side view of the pipe 3 crosses the horizontal plane at an angle of about 1.4 ° so that the outer end side is lower and the inner end side is higher. (FIG. 2). At this time, in this embodiment, the upper side in the side view of the pipe is parallel to the horizontal plane.

図３は、建築中の木造住宅の壁４にこの円錐状傾斜パイプ１を取付けた状態を示したものであり、円錐状傾斜パイプ１は、壁４に形成した貫通孔５に屋外側からパイプ部分を差込み、鍔２を壁面構成材６に釘打ちで固定してある。鍔２を壁面構成材６に固定すると、壁面構成材６は予め垂直に構成されているから、円錐状傾斜パイプ１の側面視下辺７は設定された角度、すなわち、この実施例では水平面に対して約１．４°の角度で外端側が低く傾斜して壁４に固定される。壁４の屋内外方向の厚さはこの場合１８０ｍｍであるから、円錐状傾斜パイプ１のパイプ３は屋外側と屋内側に突出する。 FIG. 3 shows a state in which the conical inclined pipe 1 is attached to a wall 4 of a wooden house under construction. The conical inclined pipe 1 is connected to a through hole 5 formed in the wall 4 from outside. The flange 2 is fixed to the wall component 6 by nailing. When the flange 2 is fixed to the wall component 6, the wall component 6 is configured vertically in advance, so that the lower side 7 of the conical inclined pipe 1 in a side view is set at a set angle, that is, in this embodiment, with respect to a horizontal plane. The outer end side is fixed to the wall 4 at an angle of about 1.4 ° with a low inclination. Since the thickness of the wall 4 in the indoor and outdoor directions is 180 mm in this case, the pipe 3 of the conical inclined pipe 1 projects to the outdoor side and the indoor side.

円錐状傾斜パイプ１の屋外側の突出部分には換気フード８が取付けられて風雨の侵入や昆虫、鳥などの侵入を防止する。屋内端側には、この場合、スパイラル管のダクト９が接続される。接続はパイプ３の内端側の径が小さいのでダクト９を接続しやすく、また、パイプ３とダクト９の嵌合部が密着する。 A ventilation hood 8 is attached to a protruding portion on the outdoor side of the conical inclined pipe 1 to prevent the invasion of wind and rain and the invasion of insects, birds, and the like. In this case, a spiral pipe duct 9 is connected to the indoor end side. Since the diameter of the inner end side of the pipe 3 is small, the duct 9 can be easily connected, and the fitting portion between the pipe 3 and the duct 9 is in close contact.

図４は第２の実施例である。第１の実施例と異なる点は、パイプ３が回転体としての円錐体の一部であり、その中心軸ｐが水平となり、パイプ３の側面視下辺と上辺が約０．７°角度を持った傾斜となる。パイプ３の側面視下辺７の傾斜は外端側が低く内端側が高い。その傾斜は前記のように０．７°であるが、雨水や結露水が室内側へ侵入するのを防止するのに充分である。この、円錐状傾斜パイプは、パイプ３を回転による円錐体の一部として形成できるので製造が容易である。 FIG. 4 shows a second embodiment. The difference from the first embodiment is that the pipe 3 is a part of a conical body as a rotating body, the central axis p thereof is horizontal, and the lower side and the upper side of the pipe 3 in a side view have an angle of about 0.7 °. It becomes a slope. The inclination of the lower side 7 of the pipe 3 in the side view is lower on the outer end side and higher on the inner end side. Although the inclination is 0.7 ° as described above, it is sufficient to prevent rainwater and dew condensation water from entering the room. This conical inclined pipe is easy to manufacture because the pipe 3 can be formed as a part of a conical body by rotation.

図５は第３の実施例であり、第１、第２の実施例と素材が異なり、スチール製である。素材としてのスチール板の厚さはこの場合０．８ｍｍであり、パイプ３の側面視下辺と同上辺の傾斜程度は第１、第２実施例の場合と同様である。合成樹脂製の場合に比べて素材が薄い分だけパイプ３の外径を小さくすることができる。鍔２とパイプ３は溶接などにより固定する。 FIG. 5 shows a third embodiment, which is different from the first and second embodiments in the material and is made of steel. In this case, the thickness of the steel plate as a material is 0.8 mm, and the degree of inclination of the lower side and the upper side of the pipe 3 in the side view is the same as in the first and second embodiments. The outer diameter of the pipe 3 can be reduced by the thinner material compared to the case made of synthetic resin. The flange 2 and the pipe 3 are fixed by welding or the like.

その他の実施例として、図５に誇張して示すように、パイプ３の外端側の面ｓ１、内端側の面ｓ２を面ｑ１、ｑ２のように鍔２と平行に形成することがある。このように形成すると、端面が正面を向くので作業者が換気フード８やダクト９を正確に嵌め込みやすい。 As another example, as shown in an exaggerated manner in FIG. 5, a surface s1 on the outer end side and a surface s2 on the inner end side of the pipe 3 may be formed parallel to the flange 2 like surfaces q1 and q2. . When formed in this manner, the end face faces forward, so that the operator can easily fit the ventilation hood 8 and the duct 9 accurately.

以上、実施例を示したが、鍔２の位置、鍔２やパイプ３の寸法は基本的に任意である。また、鍔２を壁４に固定する手段は釘打ちに限らない。木造住宅以外に用いることもできる。 Although the embodiment has been described above, the position of the flange 2 and the dimensions of the flange 2 and the pipe 3 are basically arbitrary. The means for fixing the flange 2 to the wall 4 is not limited to nailing. It can be used for other than wooden houses.
