Description

本発明は、壁部に設けられる開口を挿通する状態で取り付けられる直管部材の取付構造に関する。 The present invention relates to an attachment structure for a straight pipe member attached in a state of being inserted through an opening provided in a wall portion.

従来、壁部に設けられる開口を挿通される状態で取り付けられる直管部材の取付構造としては、特許文献１の図１２に示されるように、施工後に、開口と直管部材との間から、壁外から壁内へ向けて雨水等が浸入することを防止するべく、開口に対して内径側に、パッキンを固定し、当該パッキンに形成している挿通孔に対して直管部材を挿入し、挿通孔と直管部材との間の部位を、コーキング材等でシールする取付構造が知られている。
説明を追加すると、パッキンは、壁部の壁面に直交する方向視で、環形状を有しており、その外形部位に壁部の板厚と同程度の間隙を備え、当該間隙に壁部を挟み込む状態で、開口に固定されている。 Conventionally, as an attachment structure of a straight pipe member attached in a state where the opening provided in the wall portion is inserted, as shown in FIG. 12 of Patent Document 1, after construction, from between the opening and the straight pipe member, In order to prevent rainwater and the like from entering the wall from the outside of the wall, a packing is fixed on the inner diameter side with respect to the opening, and a straight pipe member is inserted into the insertion hole formed in the packing.

特許文献１に開示の技術では、まずもって、壁部の壁面に直交する方向視において、壁部と直管部材の間には、パッキンが設けられているだけである。このため、壁部と直管部材との間の強度は、パッキンの硬度に依存するから、パッキンの硬度を下げ難く、パッキンの硬度が下げられない場合、パッキンの弾性変形が制限されるため、パッキンの挿通部を拡径し難くなり、直管部材の管径に応じてパッキンを用意する必要があった。 In the technique disclosed in Patent Document 1, first, only a packing is provided between the wall portion and the straight pipe member when viewed in a direction orthogonal to the wall surface of the wall portion. For this reason, since the strength between the wall portion and the straight pipe member depends on the hardness of the packing, it is difficult to reduce the hardness of the packing, and when the hardness of the packing cannot be reduced, the elastic deformation of the packing is limited. It becomes difficult to expand the diameter of the insertion portion of the packing, and it is necessary to prepare a packing according to the pipe diameter of the straight pipe member.

本発明は、上述の課題に鑑みてなされたものであり、その目的は、異なる管径の直管部材に対しても共通して使用できながらも、取付部位毎での耐水性能を一定以上に維持できる直管部材の取付構造を提供する点にある。 The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a water resistance performance at a certain level or more for each attachment site while being commonly used for straight pipe members having different pipe diameters. It is in the point which provides the attachment structure of the straight pipe member which can be maintained.

上記目的を達成するための直管部材の取付構造は、
壁部に設けられる開口を挿通する状態で取り付けられる直管部材の取付構造であって、その特徴構成は、
前記壁部の壁面に直交する方向視で、外径が前記開口よりも大径であると共に、前記開口と重なる部位に前記直管部材を挿通可能な挿通部を有する環状板部材と、
前記壁部の壁面に直交する方向視で、前記開口に位置する前記直管部材の直径よりも小径のシール開孔を有し、前記シール開孔の孔外径に第１リブ部を有すると共に前記開口よりも大径の環状の第２リブ部を有する環状シール部材とを備え、
前記直管部材を前記開口に位置させ、前記挿通部に挿通させ、且つ前記シール開孔を拡径して弾性変形させた状態で挿通させると共に、前記環状板部材と前記壁部との間にて前記環状シール部材の前記第２リブ部を挟持する取付状態をとり、
前記環状シール部材は、前記第１リブ部と前記第２リブ部との間に薄板形状部を備え、
前記環状シール部材は、前記取付状態で、前記壁部の壁面に直交する方向において、前記第１リブ部と前記第２リブ部の厚みを、前記薄板形状部よりも厚く構成している点にある。 The mounting structure of the straight pipe member for achieving the above object is as follows:
It is a mounting structure of a straight pipe member that is mounted in a state of being inserted through an opening provided in a wall, and its characteristic configuration is
An annular plate member having an insertion portion through which the straight pipe member can be inserted into a portion overlapping with the opening, with an outer diameter being larger than the opening in a direction perpendicular to the wall surface of the wall portion,
As viewed in a direction orthogonal to the wall surface of the wall portion, the seal opening has a seal opening smaller in diameter than the diameter of the straight pipe member positioned in the opening, and has a first rib portion on the outer diameter of the seal opening. An annular seal member having an annular second rib portion having a larger diameter than the opening;
The straight pipe member is positioned in the opening, inserted through the insertion portion, and inserted in a state where the seal opening is expanded and elastically deformed, and between the annular plate member and the wall portion. preparative mounted state sandwiching the second rib portion of the annular seal member Te is,
The annular seal member includes a thin plate-shaped portion between the first rib portion and the second rib portion,
The annular seal member is configured in such a manner that, in the attached state, the first rib portion and the second rib portion are thicker than the thin plate-shaped portion in a direction perpendicular to the wall surface of the wall portion. is there.

上記特徴構成によれば、壁部の壁面に直交する断面視において、壁部と開口に位置する直管部材との間には、環状板部材が設けられているため、当該環状板部材にて、壁部と直管部材との間の強度を維持できるから、環状シール部材の硬度を十分に低いものとできる。
これにより、環状シール部材のシール開孔の孔径を、想定される直管部材の管径よりも小さいものとして、シール開孔に直管部材が挿通された場合にそのシール開孔を弾性変形により拡径する形態で、シール開孔にて直管部材の外径を水密にシールできる。特に、上記特徴構成にあっては、環状シール部材の硬度を十分に小さくできるから、直管部材の管径が大きくなる場合にも、当該大径の直管部材のシール開孔への挿通に伴う弾性変形を許容する形態で、シール開孔にて直管部材の外径を水密にシールできる。
更には、環状シール部材は、第１リブ部と第２リブ部との双方を備えることにより、第１リブ部により直管部材の外径部に対し水密に密着可能となると共に、第２リブ部により環状板部材の外径部と壁部との間の水密性及び耐水性を向上することができる。
更に、上記特徴構成によれば、環状シール部材が、取付状態において環状板部材と壁部との間をシールする第１リブ部と、取付状態において直管部材をシールするシール開孔の孔外径部に設けられた第２リブ部との厚みを、他の部位（薄板形状部）よりも厚く構成することで、水密性が要求される部位を、より確実にシールできる。
また、壁部の壁面に直交する方向視において、第１リブ部と第２リブ部との間に薄板形状部を設けているから、第２リブ部の弾性変形の度合を高めるべく環状シール部材の硬度を低くした場合であっても、薄板形状部が当該第２リブ部を外径側から内径側へ向けて付勢するので、第２リブ部と直管部材との間の水密性を良好に確保できる。
以上より、異なる管径の直管部材に対しても共通して使用できながらも、取付部位毎での耐水性能を一定以上に維持できる直管部材の取付構造を提供できる。 According to the above characteristic configuration, in the cross-sectional view orthogonal to the wall surface of the wall portion, the annular plate member is provided between the wall portion and the straight pipe member positioned at the opening. Since the strength between the wall portion and the straight pipe member can be maintained, the hardness of the annular seal member can be made sufficiently low.
As a result, the hole diameter of the seal opening of the annular seal member is made smaller than the assumed pipe diameter of the straight pipe member, and when the straight pipe member is inserted into the seal opening, the seal opening is elastically deformed. In the form of expanding the diameter, the outer diameter of the straight pipe member can be sealed in a watertight manner by the seal opening. In particular, in the above characteristic configuration, since the hardness of the annular seal member can be sufficiently reduced, even when the pipe diameter of the straight pipe member is increased, the large diameter straight pipe member can be inserted into the seal opening. The outer diameter of the straight pipe member can be sealed in a watertight manner through the seal opening in a form that allows the accompanying elastic deformation.
Furthermore, the annular seal member includes both the first rib portion and the second rib portion, so that the first rib portion can be water-tightly adhered to the outer diameter portion of the straight pipe member, and the second rib. The portion can improve water tightness and water resistance between the outer diameter portion of the annular plate member and the wall portion.
Further, according to the above-described characteristic configuration, the annular seal member has a first rib portion that seals between the annular plate member and the wall portion in the attached state, and a seal opening that seals the straight pipe member in the attached state. By configuring the thickness of the second rib portion provided in the diameter portion to be thicker than other portions (thin plate-shaped portions), it is possible to more reliably seal the portion requiring watertightness.
In addition, since the thin plate-shaped portion is provided between the first rib portion and the second rib portion in a direction perpendicular to the wall surface of the wall portion, an annular seal member is provided to increase the degree of elastic deformation of the second rib portion. Even when the hardness of the thin plate portion is lowered, the thin plate-shaped portion urges the second rib portion from the outer diameter side toward the inner diameter side, so that the water tightness between the second rib portion and the straight pipe member is improved. It can be secured well.
From the above, it is possible to provide a mounting structure for a straight pipe member that can be used in common for straight pipe members having different pipe diameters, and that can maintain water resistance performance at a certain level or more for each mounting site.

上記目的を達成するための直管部材の取付構造は、
壁部に設けられる開口を挿通する状態で取り付けられる直管部材の取付構造であって、その特徴構成は、
前記壁部の壁面に直交する方向視で、外径が前記開口よりも大径であると共に、前記開口と重なる部位に前記直管部材を挿通可能な挿通部を有する環状板部材と、
前記壁部の壁面に直交する方向視で、前記開口に位置する前記直管部材の直径よりも小径のシール開孔を有し、前記シール開孔の孔外径に第１リブ部を有すると共に前記開口よりも大径の環状の第２リブ部を有する環状シール部材とを備え、
前記直管部材を前記開口に位置させ、前記挿通部に挿通させ、且つ前記シール開孔を拡径して弾性変形させた状態で挿通させると共に、前記環状板部材と前記壁部との間にて前記環状シール部材の前記第２リブ部を挟持する取付状態をとり、
前記環状板部材は、その外径部と前記壁部との間にコーキング材を受け入れ保持する第１保持部位を有すると共に、前記挿通部と前記直管部材との間にコーキング材を受け入れ保持する第２保持部位を有する点にある。 The mounting structure of the straight pipe member for achieving the above object is as follows:
It is a mounting structure of a straight pipe member that is mounted in a state of being inserted through an opening provided in a wall, and its characteristic configuration is
An annular plate member having an insertion portion through which the straight pipe member can be inserted into a portion overlapping with the opening, with an outer diameter being larger than the opening in a direction perpendicular to the wall surface of the wall portion,
As viewed in a direction orthogonal to the wall surface of the wall portion, the seal opening has a seal opening smaller in diameter than the diameter of the straight pipe member positioned in the opening, and has a first rib portion on the outer diameter of the seal opening. An annular seal member having an annular second rib portion having a larger diameter than the opening;
The straight pipe member is positioned in the opening, inserted through the insertion portion, and inserted in a state where the seal opening is expanded and elastically deformed, and between the annular plate member and the wall portion. Taking the mounting state to sandwich the second rib portion of the annular seal member,
The annular plate member has a first holding portion that receives and holds the caulking material between the outer diameter portion and the wall portion, and receives and holds the caulking material between the insertion portion and the straight pipe member. It has a second holding part.

上記特徴構成によれば、壁部の壁面に直交する断面視において、壁部と開口に位置する直管部材との間には、環状板部材が設けられているため、当該環状板部材にて、壁部と直管部材との間の強度を維持できるから、環状シール部材の硬度を十分に低いものとできる。
これにより、環状シール部材のシール開孔の孔径を、想定される直管部材の管径よりも小さいものとして、シール開孔に直管部材が挿通された場合にそのシール開孔を弾性変形により拡径する形態で、シール開孔にて直管部材の外径を水密にシールできる。特に、上記特徴構成にあっては、環状シール部材の硬度を十分に小さくできるから、直管部材の管径が大きくなる場合にも、当該大径の直管部材のシール開孔への挿通に伴う弾性変形を許容する形態で、シール開孔にて直管部材の外径を水密にシールできる。
更には、環状シール部材は、第１リブ部と第２リブ部との双方を備えることにより、第１リブ部により直管部材の外径部に対し水密に密着可能となると共に、第２リブ部により環状板部材の外径部と壁部との間の水密性及び耐水性を向上することができる。
以上より、異なる管径の直管部材に対しても共通して使用できながらも、取付部位毎での耐水性能を一定以上に維持できる直管部材の取付構造を提供できる。
尚、従来技術に示すような取付構造を採用する場合、住居の壁部に対して直管部材を取り付ける場合、コーキング材をどの程度、塗布すれば良いかが取付施行者に分かり難く、結果的に、取付部位毎で耐水性能にムラが生じる虞があり、改善の余地があった。
上記特徴構成にあっては、環状板部材に関し、その外径部と壁部との間にコーキング材を受け入れ保持する第１保持部位を備えると共に、挿通部と直管部材との間にコーキング材を受け入れ保持する第２保持部位を備えることで、取付施行者にコーキング材を塗布する部位及び塗布量を直感的に知らしめることができる。これにより、施工性の向上を図ることができると共に、施工精度を向上させて耐水性能の向上を図ることができる。 According to the above characteristic configuration, in the cross-sectional view orthogonal to the wall surface of the wall portion, the annular plate member is provided between the wall portion and the straight pipe member positioned at the opening. Since the strength between the wall portion and the straight pipe member can be maintained, the hardness of the annular seal member can be made sufficiently low.
As a result, the hole diameter of the seal opening of the annular seal member is made smaller than the assumed pipe diameter of the straight pipe member, and when the straight pipe member is inserted into the seal opening, the seal opening is elastically deformed. In the form of expanding the diameter, the outer diameter of the straight pipe member can be sealed in a watertight manner by the seal opening. In particular, in the above characteristic configuration, since the hardness of the annular seal member can be sufficiently reduced, even when the pipe diameter of the straight pipe member is increased, the large diameter straight pipe member can be inserted into the seal opening. The outer diameter of the straight pipe member can be sealed in a watertight manner through the seal opening in a form that allows the accompanying elastic deformation.
Furthermore, the annular seal member includes both the first rib portion and the second rib portion, so that the first rib portion can be water-tightly adhered to the outer diameter portion of the straight pipe member, and the second rib. The portion can improve water tightness and water resistance between the outer diameter portion of the annular plate member and the wall portion.
From the above, it is possible to provide a mounting structure for a straight pipe member that can be used in common for straight pipe members having different pipe diameters, and that can maintain water resistance performance at a certain level or more for each mounting site.
In addition, when adopting the mounting structure as shown in the prior art, when mounting a straight pipe member on the wall of a residence, it is difficult for the mounting operator to know how much caulking material should be applied. In addition, there is a possibility that unevenness in water resistance performance may occur in each attachment site, and there is room for improvement.
In the above characteristic configuration, the annular plate member includes a first holding portion that receives and holds the caulking material between the outer diameter portion and the wall portion, and the caulking material between the insertion portion and the straight pipe member. By providing the 2nd holding | maintenance site | part which receives and hold | maintains, the site | part which apply | coats a caulking material, and the application quantity can be made to know intuitively. Thereby, while being able to aim at improvement of workability, construction accuracy can be improved and water resistance performance can be improved.

直管部材の取付構造の更なる特徴構成は、
前記環状板部材の前記第１保持部位は、前記環状板部材の前記外径部に沿う円環形状で、且つ前記壁部の壁面に直交する断面視でその一部を前記壁部の壁面にて構成されるＵ字形状であり、
前記環状板部材の前記第２保持部位は、前記挿通部に位置する前記直管部材を外囲する筒形状である点にある。 Further features of the straight pipe member mounting structure
The first holding portion of the annular plate member has an annular shape along the outer diameter portion of the annular plate member, and a part of the first holding portion on the wall surface of the wall portion in a cross-sectional view orthogonal to the wall surface of the wall portion. Is a U-shaped configuration,
The second holding portion of the annular plate member is in a cylindrical shape that surrounds the straight pipe member positioned in the insertion portion.

上記特徴構成によれば、第１保持部位と第２保持部位との双方を、塗布時には比較的流動性の高いコーキング材を保持し易い構成とでき、施工性を向上できる。 According to the above characteristic configuration, both the first holding portion and the second holding portion can be configured to easily hold a caulking material having a relatively high fluidity during application, and workability can be improved.

直管部材の取付構造の更なる特徴構成は、
前記環状板部材は、前記壁部の壁面に直交する方向視で、前記取付状態において、前記環状シール部材の前記第２リブ部よりも外径側で、前記第１保持部位よりも内径側に、前記壁部にビス止めされるビス止め環状部を備え、
前記壁部の壁面に直交する方向視で、前記取付状態において、前記環状板部材の前記ビス止め環状部と前記壁部との間に挟持される形態で、前記壁部の凹凸を吸収する環状の凹凸吸収部材を備える点にある。 Further features of the straight pipe member mounting structure
In the attached state, the annular plate member is closer to the outer diameter side than the second rib portion of the annular seal member and closer to the inner diameter side than the first holding portion, in a direction view perpendicular to the wall surface of the wall portion. A screwing annular part screwed to the wall part,
An annular shape that absorbs irregularities in the wall portion in a form that is sandwiched between the screw-fixed annular portion of the annular plate member and the wall portion in the attached state in a direction perpendicular to the wall surface of the wall portion. It is in the point provided with this uneven | corrugated absorption member.

直管部材が取り付けられる壁部に凹凸がある場合、環状板部材と壁部とをビス止めすると、環状板部材と壁部との間に間隙が生じることとなり、当該間隙から雨水等が浸入する可能性が高くなる。
上記特徴構成によれば、環状板部材のビス止め環状部と壁部との間に、環状の凹凸吸収部材を配設するから、ビス止め環状部と壁部との間の間隙を当該凹凸吸収部材にて埋めて、水密性をより一層高めることができる。 When the wall portion to which the straight pipe member is attached has irregularities, if the annular plate member and the wall portion are screwed, a gap is generated between the annular plate member and the wall portion, and rainwater or the like enters from the gap. The possibility increases.
According to the above characteristic configuration, since the annular uneven absorption member is disposed between the screwing annular portion of the annular plate member and the wall portion, the gap between the screwing annular portion and the wall portion is absorbed by the unevenness. It is possible to further enhance the water tightness by filling with a member.

直管部材の取付構造の更なる特徴構成は、
前記壁部は、室を構成する外壁であり、
前記直管部材は、ガス接続具を接続自在な接続部を有するガス栓本体である点にある。 Further features of the straight pipe member mounting structure
The wall portion is an outer wall constituting a chamber,
The straight pipe member is a gas plug main body having a connection portion to which a gas connector can be freely connected.

ガス栓本体を取り付ける場合には、室を形成する外壁と内壁との間隔によっては、ガス栓本体が外壁に位置する場合がある。
これまで説明してきた取付構造であれば、このような構成であっても、環状シール部材のシール開孔がガス栓本体の外径部位に隙間なく密着して、水密性を良好に発揮できる。 When the gas stopper main body is attached, the gas stopper main body may be located on the outer wall depending on the distance between the outer wall and the inner wall forming the chamber.
With the mounting structure described so far, even with such a configuration, the seal opening of the annular seal member is in close contact with the outer diameter portion of the gas plug body, and the water tightness can be satisfactorily exhibited.
