Description

本発明は、例えば一戸建住宅等の屋外に設置される給湯器等の屋外機器から延びる送液用の配管等を、屋外と屋内とを仕切る外壁等を貫通して配設するための壁貫通配管の壁貫通構造及び壁貫通配管の壁通し具に関する。   The present invention is, for example, a wall penetration for disposing a liquid feeding pipe extending from an outdoor device such as a water heater installed outdoors such as a detached house through an outer wall or the like that partitions the outdoor from an indoor. The present invention relates to a wall penetration structure for piping and a wall threading tool for wall penetration piping.

従来、住宅の屋外に設置される給湯器に接続される配管を屋内へ引き込む技術が知られている(例えば特許文献1参照。)。   2. Description of the Related Art Conventionally, a technique for drawing a pipe connected to a water heater installed outdoors in a house indoors is known (see, for example, Patent Document 1).

この従来技術は、壁に通孔(設置穴)を設け、この通孔に屋外側から固定具を取付け、鞘管と、この鞘管の中に通される配管とからなる給湯管の一端を室内側の分配器(ヘッダー)に取付け、配管のみを固定具に通して屋外側の給湯器に取付けるものである。   In this prior art, a through-hole (installation hole) is provided in a wall, a fixture is attached to the through-hole from the outdoor side, and one end of a hot water supply pipe comprising a sheath pipe and a pipe passed through the sheath pipe is provided. It is attached to the indoor distributor (header), and only the piping is passed through the fixture and attached to the outdoor water heater.

この際、壁に固定具を取付け、分配器(ヘッダー)から固定具までは配管と鞘管とからなる給湯管を配設し、固定具の位置で鞘管を切断し、この切断された端部を固定具に当接させ、固定具の屋外側に斜め上向きに突出する止水部材に配管を通すことによって、この配管のみを壁に貫通させ、この配管の中間部を固定具に固定しており、屋外側に引き出された配管は給湯器に取付けられている。
特開平9−105482号公報(図3)
At this time, a fixing tool is attached to the wall, a hot water supply pipe composed of a pipe and a sheath pipe is provided from the distributor (header) to the fixing tool, and the sheath pipe is cut at the position of the fixing tool. The part is brought into contact with the fixture, and the pipe is passed through a water-stopping member that projects obliquely upward to the outdoor side of the fixture, so that only this pipe passes through the wall, and the intermediate part of this pipe is fixed to the fixture. The piping drawn to the outdoor side is attached to the water heater.
JP-A-9-105482 (FIG. 3)

前記従来技術は壁に対して配管を斜めに貫通させるので、この配管を壁の内外面に沿わす場合に配管への負荷が少なく、且つ、屋外側から配管を挿脱して更新できる点で優れている。   Since the above-mentioned conventional technology penetrates the pipe diagonally with respect to the wall, it is excellent in that the load on the pipe is small when the pipe runs along the inner and outer surfaces of the wall and that the pipe can be inserted and removed from the outdoor side for renewal. ing.

しかし、壁に対して屋外側に突出する斜状の止水部材とこれとは別の鞘管とは結合されていないので、これら止水部材と鞘管とに配管を通すときに鞘管又は止水部材の端部に配管の先端が当たって通しづらいと共に、屋外側から配管を通すときに鞘管が配管によって押し動かされ易いので、配管を通す作業性がよくないという問題がある。   However, since the oblique water-stopping member projecting to the outdoor side with respect to the wall is not connected to another sheath pipe, the sheath pipe or the pipe is passed through the water-stopping member and the sheath pipe. There is a problem that the tip of the pipe hits the end of the water stop member and it is difficult to pass the pipe, and the sheath pipe is easily pushed by the pipe when passing the pipe from the outdoor side, so that the workability through the pipe is not good.

又、前記従来技術において配管を屋外側に引き出す際に、その引き出し力が屋外側の固定具に作用するから、この力が壁への固定具の固定箇所に集中して、固定具が外れたり、あるいは固定具と壁との間の防水性が損なわれるおそれがある。   Further, when the piping is pulled out to the outdoor side in the prior art, the pulling force acts on the outdoor side fixing tool, so that this force is concentrated on the fixing point of the fixing tool to the wall and the fixing tool is detached. Alternatively, the waterproofness between the fixture and the wall may be impaired.

さらに、前記従来技術では配管のみを貫通させる止水部材が斜め上向きとなっているので、配管を屋外側から斜め下向きに挿入するには適しているが、斜め上向きに挿入するには適当ではないと共に、配管を屋外側に引き出す際に、配管を引っ張り上げることが必要であるので作業性がよくないという問題がある。しかも、鞘管が固定具の位置において途切れているので、水漏れを起こすおそれがある。   Furthermore, in the prior art, since the water stop member that penetrates only the pipe is inclined upward, it is suitable for inserting the pipe diagonally downward from the outdoor side, but not suitable for inserting diagonally upward. At the same time, there is a problem that workability is not good because it is necessary to pull up the pipe when the pipe is pulled out to the outside. Moreover, since the sheath tube is interrupted at the position of the fixture, there is a risk of water leakage.

前記従来技術では、例えば屋外の給湯器などが上方に位置して、屋外から屋内に向うにしたがって前記給湯器などから供給される湯などを上方から下方に向って導くこととなる。このため、前記配管を屋外から屋内に向うにしたがって上方から下方に向かって傾けて配置することとなる。   In the prior art, for example, an outdoor water heater is positioned above, and hot water supplied from the water heater or the like is guided from above to below as it goes indoors from the outdoors. For this reason, the piping is inclined from the upper side to the lower side as it goes indoors from the outdoors.

前記配管が、屋外から屋内に向うにしたがって上方から下方に向かって傾けて配置されると、雨水などが前記配管の外表面などを伝わって屋内に侵入する恐れがあった。   When the piping is arranged to be inclined downward from above as it goes indoors from the outside, there is a risk that rainwater or the like may enter the indoor via the outer surface of the piping.

本発明が解決しようとする第1の課題は、住宅の壁に鞘管を無理に曲げることなく貫通させて壁に沿わせて配設できると共に、この鞘管内に通される配管も無理に曲げることなく配設できる壁貫通配管の壁貫通構造及び壁貫通配管の壁通し具を得ることにある。   The first problem to be solved by the present invention is that the sheath pipe can be penetrated through the wall of the house without forcibly bending it, and can be arranged along the wall, and the pipe passed through the sheath pipe is also bent forcibly. An object of the present invention is to obtain a wall through structure of a wall through pipe and a wall through tool of the wall through pipe that can be disposed without any problem.

又、本発明が解決しようとする第2の課題は、前記第1の課題を解決するにあたって、雨水などの浸入を防止できる壁貫通配管の壁通し構造を得ることにある。   A second problem to be solved by the present invention is to obtain a wall through structure of a wall through pipe that can prevent intrusion of rainwater or the like in solving the first problem.

又、本発明が解決しようとする第3の課題は、前記第1の課題を解決するにあたって、水漏れなどを起こした際にも屋内への浸水を防止できる壁貫通配管の壁通し構造を得ることにある。   Further, the third problem to be solved by the present invention is to solve the first problem by obtaining a wall through structure of a wall through pipe that can prevent indoor inundation even when a water leak occurs. There is.

請求項1の発明に係る壁貫通配管の壁通し具は、住宅の壁を斜めに貫通する設置穴に挿通されるとともに、前記壁の一面に引掛るフランジ部を有し、かつ、前記壁を途切れることなく貫通する鞘管が通される筒状の鞘管ガイドと、前記壁の他面から斜めに突出した前記鞘管ガイドの部分の外周に摺動可能に嵌合して設けられ前記フランジ部との間に前記壁を挟む壁押さえと、この壁押さえと前記鞘管ガイドとにわたって設けられ前記壁押さえを前記壁に押付けた状態に保持する固定手段と、を具備したものである。   A wall threading tool for a wall through pipe according to the invention of claim 1 is inserted into an installation hole that obliquely penetrates a wall of a house, has a flange portion that hooks on one surface of the wall, and the wall The flange that is provided by being slidably fitted to the outer periphery of a cylindrical sheath tube guide through which a sheath tube that penetrates without interruption is passed, and the portion of the sheath tube guide that projects obliquely from the other surface of the wall And a fixing means provided between the wall press and the sheath tube guide to hold the wall press against the wall.

この請求項1の発明に係る壁貫通配管の壁通し具を壁に設置するには、まず、壁を斜めに貫通した設置穴に対して壁の一面側又は他面側から、壁押さえが嵌合される側の端部を先頭にして鞘管ガイドをそのフランジ部が壁に当接するまで挿通することにより、このガイドを壁に対して斜めに貫通させる。次に、壁より斜めに突出した鞘管ガイドの前記端部の外周に壁押さえを嵌合させる。最後に、鞘管ガイドと壁押さえとにわたって設けられる固定手段を操作して、壁押さえを鞘管ガイドの軸方向に沿って壁側に移動させて壁に押付けた状態に保持する。それにより、フランジ部と壁押さえとの間に壁を挟んだ状態で壁通し具を壁に対して斜めに設置できる。   In order to install the wall through tool of the wall through pipe according to the first aspect of the present invention on the wall, first, a wall presser is fitted from one side or the other side of the wall with respect to the installation hole obliquely penetrating the wall. The guide is penetrated obliquely with respect to the wall by inserting the sheath tube guide with the end of the mating side as the head until the flange portion abuts against the wall. Next, a wall presser is fitted to the outer periphery of the end portion of the sheath guide that protrudes obliquely from the wall. Finally, the fixing means provided between the sheath tube guide and the wall retainer is operated to move the wall retainer to the wall side along the axial direction of the sheath tube guide and keep it pressed against the wall. Accordingly, the wall threading tool can be installed obliquely with respect to the wall in a state where the wall is sandwiched between the flange portion and the wall press.

したがって、この後には、壁を斜めに貫通した鞘管ガイドに対して前記一面側又は他面側から鞘管を通して、この鞘管を壁に対して斜めに貫通させた後、この鞘管内に配管を挿入することにより、鞘管内を通して所定の場所に配管を導いて配設できる。このように請求項1の発明に係る壁貫通配管の壁通し具においては、壁に設けた斜めの設置穴を貫通する筒状の鞘管ガイドを備えているから、このガイドに鞘管を通すことにより、鞘管を、無理に曲げることなく壁に斜めに貫通させて壁に沿って配設できる。したがって、例えば、外壁裏の狭い壁裏空間の内部にも無理なく鞘管を配設できると共に、この鞘管の内部に通して案内させる配管も無理に曲げることなく屋内等へと配設できる。   Therefore, after this, after passing through the sheath tube from the one surface side or the other surface side with respect to the sheath tube guide that obliquely penetrates the wall, the sheath tube is obliquely penetrated with respect to the wall, and then the pipe is installed in the sheath tube. By inserting the pipe, the pipe can be guided to a predetermined place through the inside of the sheath pipe. Thus, in the wall threading tool of the wall through pipe according to the first aspect of the present invention, since the cylindrical sheath tube guide penetrating the oblique installation hole provided in the wall is provided, the sheath tube is passed through this guide. Thus, the sheath tube can be disposed along the wall so as to penetrate obliquely through the wall without being bent excessively. Therefore, for example, a sheath pipe can be arranged without difficulty in a narrow wall space behind the outer wall, and a pipe guided through the inside of the sheath pipe can be arranged indoors without being bent excessively.

請求項2の発明に係る壁貫通配管の壁通し具は、住宅の壁を斜めに貫通する設置穴に挿通されるとともに、前記壁の一面に固定されるフランジ部を有し、かつ、前記壁を途切れることなく貫通する鞘管が通される筒状の鞘管ガイドと、前記壁の他面から斜めに突出した前記鞘管ガイドの部分の外周に摺動可能に嵌合して設けられるとともに、前記壁の他面に固定されて前記壁を前記フランジ部との間に挟む壁押さえと、を具備したものである。   A wall threading tool for a wall through pipe according to the invention of claim 2 has a flange portion that is inserted into an installation hole that obliquely penetrates a wall of a house and is fixed to one surface of the wall, and the wall And a slidably fitted on the outer periphery of a portion of the tubular tube guide that projects obliquely from the other surface of the wall. And a wall presser fixed to the other surface of the wall and sandwiching the wall between the flange portion.

この請求項2の発明に係る壁貫通配管の壁通し具を壁に設置するには、まず、壁を斜めに貫通した設置穴に対して壁の一面側又は他面側から、壁押さえが嵌合される側の端部を先頭にして鞘管ガイドをそのフランジ部が壁に当接するまで挿通することにより、このガイドを壁に対して斜めに貫通させて、前記フランジ部を壁にねじ止め等により固定する。次に、壁より斜めに突出した鞘管ガイドの前記端部の外周に壁押さえを嵌合させる。最後に、壁押さえを壁にねじ止め等により固定して、この壁押さえとフランジ部との間に壁を挟んだ状態で壁通し具を壁に対して斜めに設置する。   In order to install the wall threading tool of the wall through pipe according to the invention of this second aspect on the wall, first, a wall presser is fitted from one side or the other side of the wall with respect to the installation hole obliquely penetrating the wall. Insert the sheath tube guide with the end on the mating side leading until the flange abuts against the wall, so that the guide penetrates diagonally to the wall and the flange is screwed to the wall Fix with etc. Next, a wall presser is fitted to the outer periphery of the end portion of the sheath guide that protrudes obliquely from the wall. Finally, the wall holder is fixed to the wall by screws or the like, and the wall threading tool is installed obliquely with respect to the wall in a state where the wall is sandwiched between the wall holder and the flange portion.

したがって、この後には、壁を斜めに貫通した鞘管ガイドに対して前記一面側又は他面側から鞘管を通して、この鞘管を壁に対して斜めに貫通させた後、この鞘管内に配管を挿入することにより、鞘管内を通して所定の場所に配管を導いて配設できる。このように請求項2の発明に係る壁貫通配管の壁通し具においては、壁に設けた斜めの設置穴を貫通する筒状の鞘管ガイドを備えているから、このガイドに鞘管を通すことにより、鞘管を、無理に曲げることなく壁に斜めに貫通させて壁に沿って配設できる。したがって、例えば、外壁裏の狭い壁裏空間の内部にも無理なく鞘管を配設できると共に、この鞘管の内部に通して案内させる配管も無理に曲げることなく屋内等へと配設できる。   Therefore, after this, after passing through the sheath tube from the one surface side or the other surface side with respect to the sheath tube guide that obliquely penetrates the wall, the sheath tube is obliquely penetrated with respect to the wall, and then the pipe is installed in the sheath tube. By inserting the pipe, the pipe can be guided to a predetermined place through the inside of the sheath pipe. Thus, in the wall threading tool of the wall through pipe according to the invention of the second aspect, since the cylindrical sheath tube guide penetrating the oblique installation hole provided in the wall is provided, the sheath tube is passed through this guide. Thus, the sheath tube can be disposed along the wall so as to penetrate obliquely through the wall without being bent excessively. Therefore, for example, a sheath pipe can be arranged without difficulty in a narrow wall space behind the outer wall, and a pipe guided through the inside of the sheath pipe can be arranged indoors without being bent excessively.

請求項3の発明に係る壁貫通配管の壁通し具は、住宅の壁を斜めに貫通する設置穴に挿入されるとともに、前記壁の一面に引掛るフランジ部を有し、かつ、前記壁を途切れることなく貫通する鞘管が通される筒状の第1鞘管ガイドと、前記壁の他面に引掛るフランジ部を有して前記設置穴に挿入されるとともに、前記第1鞘管ガイドに軸方向に沿って移動可能に嵌合され、かつ、前記鞘管が通される筒状の第2鞘管ガイドと、を具備したものである。   A wall threading tool for a wall through pipe according to the invention of claim 3 is inserted into an installation hole that obliquely penetrates a wall of a house, has a flange portion that hooks on one surface of the wall, and the wall A cylindrical first sheath tube guide through which a sheath tube that passes through without interruption is inserted, and a flange portion that hooks on the other surface of the wall and is inserted into the installation hole, and the first sheath tube guide And a cylindrical second sheath guide that is movably fitted along the axial direction and through which the sheath tube is passed.

この請求項3の発明に係る壁貫通配管の壁通し具を壁に設置するには、まず、壁を斜めに貫通した設置穴に対して壁の一面側から第1鞘管ガイドを、そのフランジ部が壁の一面に当接するまで挿通することにより、このガイドを壁に対して斜めに挿入させて、前記フランジ部を壁の一面側において設置穴の一端の穴縁に引掛ける。次に、壁の他面側から第2鞘管ガイドをそのフランジ部が壁の他面に当接するまで挿通して、第2鞘管ガイドを壁に対して斜めに挿入するとともに、その挿入先端部側を前記第1鞘管ガイドの挿入先端部に嵌合させる。この嵌合により軸方向に連続された両鞘管ガイドは、必要に応じて一方の鞘管ガイドの第1引掛り部と他方の鞘管ガイドに設けられた第2引掛り部との引掛かりにより連結することもできる。最後に、前記のように両鞘管ガイドが嵌合された状態で、前記他方の鞘管ガイドのフランジ部を壁の他面側に置いて設置穴の他端に引掛けて、前記両フランジ部で壁を挟んだ姿勢で壁通し具を壁に対して斜めに設置する。   In order to install the wall threading tool of the wall through pipe according to the invention of claim 3 to the wall, first, the first sheath pipe guide is flanged from the one surface side of the wall with respect to the installation hole obliquely penetrating the wall. By inserting the guide until the portion comes into contact with one surface of the wall, the guide is inserted obliquely with respect to the wall, and the flange portion is hooked on the hole edge at one end of the installation hole on the one surface side of the wall. Next, the second sheath tube guide is inserted from the other surface side of the wall until the flange portion abuts against the other surface of the wall, and the second sheath tube guide is inserted obliquely with respect to the wall, and the insertion tip The part side is fitted to the insertion tip of the first sheath tube guide. The two-sheath tube guides that are axially continuous by this fitting are hooked between the first hook portion of one of the sheath tube guides and the second hook portion provided on the other sheath tube guide as necessary. Can also be connected. Finally, with the two sheath tube guides fitted as described above, the flange portion of the other sheath tube guide is placed on the other side of the wall and hooked to the other end of the installation hole, and the both flanges The wall threading tool is installed obliquely with respect to the wall in a posture in which the wall is sandwiched between the parts.

したがって、この後には、壁を斜めに貫通し軸方向に連続して接続された第1、第2の鞘管ガイドに対して前記一面側又は他面側から鞘管を通して、この鞘管を壁に対して斜めに貫通させた後、この鞘管内に配管を挿入することにより、鞘管内を通して所定の場所に配管を導いて配設できる。このように請求項3の発明に係る壁貫通配管の壁通し具においては、壁に設けた斜めの設置穴で互いに嵌合することによって連結する筒状の第1、第2の鞘管ガイドを備えているから、これら鞘管ガイドに鞘管を通すことにより、鞘管を、無理に曲げることなく壁に斜めに貫通させて壁に沿って配設できる。したがって、例えば、外壁裏の狭い壁裏空間の内部にも無理なく鞘管を配設できると共に、この鞘管の内部に通して案内させる配管も無理に曲げることなく屋内等へと配設できる。   Therefore, after this, the sheath tube is passed through the sheath tube from the one surface side or the other surface side with respect to the first and second sheath tube guides that are obliquely penetrated through the wall and continuously connected in the axial direction. By inserting the pipe into the sheath tube after passing through the sheath pipe at an angle, the pipe can be guided to a predetermined place through the sheath pipe. Thus, in the wall through tool of the wall through pipe according to the third aspect of the present invention, the cylindrical first and second sheath tube guides connected by fitting with each other through the oblique installation holes provided in the wall are provided. Therefore, by passing the sheath tube through these sheath tube guides, the sheath tube can be disposed along the wall so as to penetrate diagonally through the wall without being bent excessively. Therefore, for example, a sheath pipe can be arranged without difficulty in a narrow wall space behind the outer wall, and a pipe guided through the inside of the sheath pipe can be arranged indoors without being bent excessively.

請求項4の発明に係る壁貫通配管の壁通し具は、住宅の壁を斜めに貫通する設置穴に挿入されるとともに、前記壁を途切れることなく貫通する鞘管が通される筒状の鞘管ガイドと、このガイドの一端部外周から一体に張り出して設けられ前記壁の一面に固定されるフランジ部と、を有したものである。   The wall through tool of the wall through pipe according to the invention of claim 4 is inserted into an installation hole that obliquely penetrates the wall of a house, and a cylindrical sheath through which a sheath pipe that penetrates the wall without interruption is passed. It has a tube guide and a flange portion that is provided so as to project integrally from the outer periphery of one end of the guide and is fixed to one surface of the wall.

この請求項4の発明に係る壁貫通配管の壁通し具を壁に設置するには、まず、壁を斜めに貫通した設置穴に対して壁の一面側又は他面側から、フランジ部が設けられていない方の鞘管ガイドの端部を先頭に、このガイドを前記フランジ部が壁に当接するまで壁に対して斜めに挿入してから、前記フランジ部を壁にねじ止め等により固定すればよい。それにより、壁通し具を壁に対して斜めに設置できる。   In order to install the wall through tool of the wall through pipe according to the invention of claim 4 on the wall, first, a flange portion is provided from one side or the other side of the wall with respect to the installation hole obliquely penetrating the wall. Insert the guide diagonally with respect to the wall until the flange part abuts against the wall, and then fix the flange part to the wall by screwing etc. That's fine. Thereby, the wall threading tool can be installed obliquely with respect to the wall.

したがって、この後には、壁を斜めに挿入された筒状の鞘管ガイドに対して前記一面側又は他面側から鞘管を通して、この鞘管を壁に対して斜めに貫通させた後、この鞘管内に配管を挿入することにより、鞘管内を通して所定の場所に配管を導いて配設できる。このように請求項4の発明に係る壁貫通配管の壁通し具においては、壁に設けた斜めの設置穴に挿入される筒状鞘管ガイドを備えているから、この斜めのガイドに鞘管を通すことにより、鞘管を、無理に曲げることなく壁に斜めに貫通させて壁に沿って配設できる。したがって、例えば、外壁裏の狭い壁裏空間の内部にも無理なく鞘管を配設できると共に、この鞘管の内部に通して案内させる配管も無理に曲げることなく屋内等へと配設できる。   Therefore, after this, after passing through the sheath tube from the one surface side or the other surface side to the cylindrical sheath tube guide inserted obliquely through the wall, By inserting the pipe into the sheath pipe, the pipe can be guided to a predetermined place through the sheath pipe. In this way, in the wall through tool of the wall through pipe according to the invention of claim 4, since the cylindrical sheath tube guide inserted into the oblique installation hole provided in the wall is provided, the sheath tube is attached to the oblique guide. By passing through, the sheath tube can be disposed along the wall so as to penetrate diagonally through the wall without forcibly bending. Therefore, for example, a sheath pipe can be arranged without difficulty in a narrow wall space behind the outer wall, and a pipe guided through the inside of the sheath pipe can be arranged indoors without being bent excessively.

請求項5の発明に係る壁貫通配管の壁貫通構造は、請求項1から4の内のいずれか一項に記載の壁通し具を使用し、その鞘管ガイドを住宅の壁に対して斜めとなる姿勢にして、この鞘管ガイドの少なくとも一部を、前記壁を斜めに貫通する設置穴に配置し、斜めの前記鞘管ガイドにその傾き方向に鞘管を通してこの鞘管を前記壁に対して途切れることなく斜めに貫通させるとともに、この斜めの鞘管内に前記壁を貫通する配管を通して案内し、この配管を曲げることなく配設している。   The wall penetration structure of the wall penetration piping which concerns on invention of Claim 5 uses the wall threading tool as described in any one of Claim 1 to 4, and the sheath pipe guide is slanted with respect to the wall of a house In such a posture, at least a part of the sheath tube guide is disposed in an installation hole obliquely penetrating the wall, and the sheath tube is passed through the sheath tube in the inclination direction of the oblique sheath tube guide and the sheath tube is placed on the wall. On the other hand, it penetrates diagonally without interruption and is guided through a pipe penetrating the wall into the oblique sheath pipe, and the pipe is arranged without bending.

この請求項5の発明は、請求項1から3の内のいずれか一項に記載の壁通し具を使用して、壁に設けた斜めの設置穴を配置した筒状の鞘管ガイドに鞘管を通すことにより、鞘管を、無理に曲げることなく壁に斜めに貫通させて壁に沿って配設できる。したがって、例えば、外壁裏の狭い壁裏空間の内部にも無理なく鞘管を配設できると共に、この鞘管の内部に通して案内させる配管も無理に曲げることなく屋内等へと配設できる。このように配管を配設できるので、この配管が送液管であって、そこから液漏れを生じた場合、漏れた液体を、壁を斜めに貫通した鞘管を通して屋外等に導出できる。   The invention of claim 5 uses a wall threading tool according to any one of claims 1 to 3 to a cylindrical sheath tube guide in which an oblique installation hole provided in the wall is arranged. By passing the tube, the sheath tube can be disposed along the wall so as to penetrate diagonally through the wall without being bent excessively. Therefore, for example, a sheath pipe can be arranged without difficulty in a narrow wall space behind the outer wall, and a pipe guided through the inside of the sheath pipe can be arranged indoors without being bent excessively. Since the pipe can be arranged in this way, when this pipe is a liquid feeding pipe and a liquid leak occurs from the pipe, the leaked liquid can be led out to the outside or the like through a sheath pipe obliquely penetrating the wall.

(実施形態1)
以下、図1〜図4を参照して本発明の第1の実施の形態に係る壁貫通配管の壁通し具を説明する。
(Embodiment 1)
Hereinafter, the wall threading tool of the wall through pipe according to the first embodiment of the present invention will be described with reference to FIGS.

図1は第1実施形態の壁貫通配管の壁通し具1を一戸建の建屋の外壁2の設置穴3に取付けて、配管4及び鞘管5を貫通させた状態を示す断面図である。   FIG. 1 is a cross-sectional view illustrating a state in which a wall threading tool 1 of a wall through pipe according to a first embodiment is attached to an installation hole 3 in an outer wall 2 of a detached building and a pipe 4 and a sheath pipe 5 are penetrated.

図2(a)及び(b)に示すように、この壁通し具1は第1壁通し部材6と第2壁通し部材7と連結手段とからなる。   As shown in FIGS. 2A and 2B, the wall threading tool 1 includes a first wall threading member 6, a second wall threading member 7, and a connecting means.

合成樹脂製の第1壁通し部材6は、住宅の壁としての外壁2の厚み方向両面に夫々開放されていると共に上下方向に長い小判形をなして設けられた設置穴3に、屋外側から嵌め込む第1筒部8と、この第1筒部8と一体に形成されて外側に張り出し、設置穴3の屋外側縁部と引掛かり合う第1フランジ部10と、第1筒部8の例えば屋外側端部に一体に形成されて第1筒部8の内側を閉じる閉塞部12と、この閉塞部12の下部に一体に形成されて屋内側から屋外側にかけて斜めに貫通する円筒形をなした鞘管ガイド13とから構成される。なお、前記設置穴3は、外壁2に対して直交する方向に沿って、前記外壁2を貫通している。   The first wall-passing member 6 made of synthetic resin is opened from the outdoor side to the installation holes 3 that are open on both sides in the thickness direction of the outer wall 2 as a house wall and are formed in a long oval shape in the vertical direction. A first tube portion 8 to be fitted, a first flange portion 10 that is formed integrally with the first tube portion 8 and projects outward, and engages with an outdoor side edge of the installation hole 3; For example, a closed portion 12 that is integrally formed on the outdoor side end portion and closes the inside of the first cylindrical portion 8, and a cylindrical shape that is integrally formed at the lower portion of the closed portion 12 and that obliquely penetrates from the indoor side to the outdoor side. And a formed sheath guide 13. The installation hole 3 penetrates the outer wall 2 along a direction orthogonal to the outer wall 2.

鞘管ガイド13はその屋内側端部が屋外側端部よりも上側に位置するように斜めに設けられ、したがって閉塞部12の一端部から斜め下向きに突設されている。さらに、鞘管ガイド13は後述する鞘管5を挿通できるように鞘管5よりやや大径となっている。使用状態において鞘管ガイド13の屋内側端部は図3に示されるように設置穴3内に位置される。   The sheath tube guide 13 is provided obliquely so that the indoor side end thereof is located above the outdoor side end, and thus protrudes obliquely downward from one end of the closed portion 12. Furthermore, the sheath tube guide 13 has a slightly larger diameter than the sheath tube 5 so that the sheath tube 5 described later can be inserted. In the use state, the indoor side end of the sheath guide 13 is positioned in the installation hole 3 as shown in FIG.

周方向に連続すると共に例えば閉塞部12と面一に連続した第1フランジ部10の外壁2側には、第1壁通し部材6を設置穴3に設置したときに、第1フランジ部10と外壁2との隙間を埋めて挟み込まれ雨水等の設置穴3への浸入を防止するための止水パッキン14aが設けられている。なお、前記隙間をコーキング処理する場合には止水パッキン14aは省略できる。   When the first wall threading member 6 is installed in the installation hole 3 on the outer wall 2 side of the first flange portion 10 that is continuous in the circumferential direction and is flush with the closing portion 12, for example, A water stop packing 14a is provided to prevent the rainwater or the like from entering the installation hole 3 by being filled with a gap with the outer wall 2. In addition, when the said clearance gap is caulk-processed, the water stop packing 14a is omissible.

閉塞部12には、この第1壁通し部材6と後述の第2壁通し部材7とを連結するための連結手段としてのねじ15をねじ込むためのねじ通孔16が第1筒部8の内側に貫通して設けられている。   The closing portion 12 has a screw through hole 16 for screwing a screw 15 as a connecting means for connecting the first wall passing member 6 and a second wall passing member 7 to be described later on the inside of the first tube portion 8. It is provided to penetrate through.

合成樹脂製の第2壁通し部材7は、外壁2に設けられた設置穴3に、屋内側から嵌め込む第2筒部17と、この第2筒部17と一体に形成されて外側に張り出し、設置穴3の屋内側縁部と引掛かり合う第2フランジ部19とからなる。周方向に連続する第2フランジ部19の外壁2側には、第2壁通し部材7を設置穴3に設置したときに、第2フランジ部19と外壁2との隙間を埋めて挟み込まれる止水パッキン14bが設けられている。この止水パッキン14bは省略してもよい。又、第2筒部17の屋外側端部の内側には、連結手段としてのねじ15を受け止めるためのねじ孔を有した螺合部21が第1壁通し部材6のねじ通孔16と対向する位置に設けられている。   The second wall-passing member 7 made of synthetic resin is formed integrally with the second cylindrical portion 17 fitted into the installation hole 3 provided in the outer wall 2 from the indoor side, and projects outward from the second cylindrical portion 17. The second flange portion 19 catches the indoor side edge portion of the installation hole 3. On the outer wall 2 side of the second flange portion 19 that is continuous in the circumferential direction, when the second wall passing member 7 is installed in the installation hole 3, the gap between the second flange portion 19 and the outer wall 2 is filled and sandwiched. A water packing 14b is provided. This water blocking packing 14b may be omitted. Further, on the inner side of the outdoor side end portion of the second cylindrical portion 17, a screwing portion 21 having a screw hole for receiving the screw 15 as a connecting means is opposed to the screw hole 16 of the first wall passing member 6. It is provided in the position to do.

壁通し具1が設置穴3に嵌め込まれるなどして取り付けられた際に、住宅の鉛直方向に沿う第1筒部8及び第2筒部17の幅Dは、鞘管5の外径dの約2から3倍以上の寸法に形成されている。このように、第1筒部8及び第2筒部17の幅Dは、鞘管5の外径dより十分大きく形成されている。   When the wall threading tool 1 is attached by being fitted into the installation hole 3 or the like, the width D of the first tube portion 8 and the second tube portion 17 along the vertical direction of the house is the outer diameter d of the sheath tube 5. The size is about 2 to 3 times or more. Thus, the width D of the first cylinder portion 8 and the second cylinder portion 17 is formed sufficiently larger than the outer diameter d of the sheath tube 5.

前記壁通し具1の具体的な寸法例を挙げると、呼び径が直径13mmの配管4を呼び径が直径28mmの鞘管5に通して、厚さ75mmの外壁2を貫通させる場合、外壁2を通る配管4及び鞘管5の外壁2に対する挿入角度が45°となるように鞘管ガイド13を閉塞部12に対して設ける。又、このとき、設置穴3の口径の最も長い方向は長さ150mm以上が望ましい。又、図3に示すように、鞘管ガイド13は鞘管5が貫通する際に接触する方向にのみ開口部があれば良く、正面から見て開口部は楕円形状でも構わない。この場合、配設に必要な壁裏空間24は幅70mm以上とする。   As a specific example of the dimensions of the wall threading tool 1, when the pipe 4 having a nominal diameter of 13 mm is passed through the sheath pipe 5 having a nominal diameter of 28 mm and penetrated through the outer wall 2 having a thickness of 75 mm, the outer wall 2 The sheath pipe guide 13 is provided with respect to the closing part 12 so that the insertion angle with respect to the outer wall 2 of the pipe 4 and the sheath pipe 5 passing through the pipe is 45 °. At this time, the longest diameter of the installation hole 3 is preferably 150 mm or more. Further, as shown in FIG. 3, the sheath tube guide 13 only needs to have an opening in a direction in which the sheath tube 5 contacts when penetrating, and the opening may be elliptical when viewed from the front. In this case, the wall space 24 necessary for the arrangement is set to have a width of 70 mm or more.

次に、外壁2への壁貫通配管の壁通し具1の取付け作業を説明する。   Next, an operation of attaching the wall threading tool 1 of the wall through pipe to the outer wall 2 will be described.

外壁2には予め前記第1、第2筒部8、17の大きさに合わせた設置穴3が、屋外側と屋内側とを連通して外壁2に対して直交する方向に沿って貫通して開けられている。まず、第1壁通し部材6を取付ける。第1壁通し部材6の第1筒部8を設置穴3の屋外側から屋内側へ向かって、第1フランジ部10が設置穴3の屋外側縁部に引掛かって止まるまで嵌め込む。このとき、第1フランジ部10と外壁2の屋外側との隙間は、第1フランジ部10の壁側に設けられた止水パッキン14aによって隙間無く塞がれる。   The outer wall 2 has an installation hole 3 that is adjusted to the size of the first and second cylindrical portions 8 and 17 in advance and communicates between the outdoor side and the indoor side along a direction orthogonal to the outer wall 2. Open. First, the first wall passing member 6 is attached. The first tubular portion 8 of the first wall passing member 6 is fitted from the outdoor side of the installation hole 3 toward the indoor side until the first flange portion 10 is hooked on the outdoor side edge of the installation hole 3 and stops. At this time, the gap between the first flange portion 10 and the outdoor side of the outer wall 2 is closed without a gap by the water stop packing 14 a provided on the wall side of the first flange portion 10.

次に、第2壁通し部材7を取付ける。第1壁通し部材6とは反対に、第2壁通し部材7の第2筒部17を設置穴3の屋内側から屋外側へ向かって、第2フランジ部19が設置穴3の屋内側縁部に引掛かって止まるまで嵌め込む。それにより、設置穴3内で第1筒部8の屋内側端部と第2筒部17の屋外側端部とが接近する。このとき、前述の第1壁通し部材6の場合と同様に、第2フランジ部19と外壁2の屋内側との隙間は、第2フランジ部19の壁側に設けられた止水パッキン14bによって隙間無く塞がれる。   Next, the second wall passing member 7 is attached. Contrary to the first wall passing member 6, the second flange portion 19 is located on the indoor side edge of the installation hole 3, with the second cylindrical portion 17 of the second wall passing member 7 directed from the indoor side to the outdoor side of the installation hole 3. Fit it until it stops and stops. Thereby, the indoor side end of the first cylinder part 8 and the outdoor side end part of the second cylinder part 17 approach in the installation hole 3. At this time, as in the case of the first wall passing member 6 described above, the gap between the second flange portion 19 and the indoor side of the outer wall 2 is caused by the water stop packing 14b provided on the wall side of the second flange portion 19. It is closed without a gap.

この後、第1壁通し部材6の閉塞部12のねじ通孔16を通して、屋外側からねじ15を第2壁通し部材7の螺合部21にねじ込むことで、第1壁通し部材6と第2壁通し部材7とを連結すると共に、止水パッキン14a、14bが外壁2の内外両壁面に夫々圧接される。以上で外壁2の設置穴3への壁貫通配管の壁通し具1の取付けが終了する。   Thereafter, the screw 15 is screwed from the outdoor side into the screwing portion 21 of the second wall passing member 7 through the screw through hole 16 of the closing portion 12 of the first wall passing member 6, thereby the first wall passing member 6 and the first wall passing member 6 are connected to the first wall passing member 6. The two-wall through member 7 is connected, and the water-stopping packings 14a and 14b are pressed against the inner and outer wall surfaces of the outer wall 2, respectively. Thus, the attachment of the wall threading tool 1 of the wall through pipe to the installation hole 3 of the outer wall 2 is completed.

この第1実施形態の壁貫通配管の壁通し具1は第1壁通し部材6と第2壁通し部材7とをねじ15により連結しているだけなので、将来この壁貫通配管の壁通し具1を取り外す必要が生じたときには、ねじ15を緩めて外すだけで、外壁2の設置穴3からこの壁貫通配管の壁通し具1を取り外すことができる。   Since the wall threading tool 1 of the wall through pipe of the first embodiment is simply connecting the first wall threading member 6 and the second wall threading member 7 with screws 15, the wall threading tool 1 of this wall through pipe in the future. When it is necessary to remove the wall through tool 1, the wall threading tool 1 of the wall through pipe can be removed from the installation hole 3 of the outer wall 2 simply by loosening and removing the screw 15.

次に、例えば給湯又は給水のための送液用の配管4及び鞘管5を、前述のようにして外壁2の設置穴3に取付けた壁貫通配管の壁通し具1に通す配設作業を説明する。配管4は架橋ポリエチレン管であって可撓性を有し、この配管4が通される鞘管5は配管4よりも硬質な合成樹脂製ではあるが、可撓性に優れた波付け管が採用されている。   Next, for example, an arrangement operation is performed in which the liquid supply pipe 4 and the sheath pipe 5 for hot water supply or water supply are passed through the wall through tool 1 of the wall through pipe attached to the installation hole 3 of the outer wall 2 as described above. explain. The pipe 4 is a cross-linked polyethylene pipe and has flexibility, and the sheath pipe 5 through which the pipe 4 passes is made of a synthetic resin harder than the pipe 4, but a corrugated pipe having excellent flexibility is used. It has been adopted.

鞘管5は、例えば屋外から屋内へと通される。すなわち、鞘管5の一端を第1壁通し部材6の鞘管ガイド13に屋外側から斜め上向きに通していく。図3及び図4(a)、(b)に示されるように、鞘管ガイド13はこの屋内側端部が屋外側端部よりも上側に在るように閉塞部12を斜めに貫通して設けられているため、鞘管ガイド13を通して屋外から屋内へと通された鞘管5は、壁通し具1をその第2壁通し部材16に引掛かることなく斜め上向きに通り抜けて外壁2の屋内側壁面に沿って上方へと押し込まれるから、図1に示されるように、外壁2と部屋の内装板23とによって作られる幅の狭い壁裏空間24や、部屋の天井25の上の屋根裏空間26にも無理に折り曲げられて座屈変形を起こすことなく配設できる。配設し終わった鞘管5は、外壁2等に適当な間隔に取付けられるU字形をなしたサドル27等を用いてずれ落ちないように固定される。   The sheath tube 5 is passed from the outside to the inside, for example. That is, one end of the sheath tube 5 is passed obliquely upward from the outdoor side through the sheath tube guide 13 of the first wall passing member 6. As shown in FIGS. 3 and 4 (a) and 4 (b), the sheath tube guide 13 obliquely penetrates the closed portion 12 so that the indoor side end portion is located above the outdoor side end portion. Therefore, the sheath tube 5 passed from the outside to the inside through the sheath guide 13 passes through the wall threading tool 1 obliquely upward without being caught by the second wall threading member 16, and the outer wall 2 is closed. Since it is pushed upward along the inner wall surface, as shown in FIG. 1, a narrow wall space 24 formed by the outer wall 2 and the interior board 23 of the room, or an attic space above the ceiling 25 of the room. 26 can be arranged without being bent by force and causing buckling deformation. The sheath tube 5 that has been disposed is fixed so as not to fall off using a U-shaped saddle 27 or the like attached to the outer wall 2 or the like at an appropriate interval.

次に、壁通し具1を斜めに貫通して鞘管ガイド13に中間部が支持された鞘管5に対して、屋外より配管4を斜め上向きに挿入することによって、この配管4を鞘管5に沿わせて配設する。鞘管5は無理に折り曲げられることなく既に必要とされる所定の位置まで配設されているので、配管4は、無理に折り曲げられて座屈変形を起こすことなく鞘管5の内部を通って所定の位置まで案内される。鞘管5の配設及び固定作業の終了後に、図3に示すように、鞘管ガイド13の屋外側の開口部において、コーキング材28による止水処理を施して鞘管5と開口部との隙間を塞ぐ。この止水処理によって、鞘管ガイド13を通して屋外から屋内へ雨水等が浸入するおそれを極めて低くできる。なお、コーキング処理に代えて鞘管ガイド13と鞘管5との間にOリングを挟んでもよく、又、これら両止水処理を兼用してもよい。   Next, the pipe 4 is inserted into the sheath pipe 5 diagonally upward from the outside with respect to the sheath pipe 5 that is obliquely penetrated through the wall threading tool 1 and is supported by the sheath pipe guide 13 at an intermediate portion. 5 along the line. Since the sheath pipe 5 is disposed to a predetermined position that is already necessary without being bent excessively, the pipe 4 passes through the inside of the sheath pipe 5 without being bent and causing buckling deformation. Guided to a predetermined position. After the sheath tube 5 is disposed and fixed, as shown in FIG. 3, a water-stopping treatment with a caulking material 28 is applied to the opening on the outdoor side of the sheath guide 13 so that the sheath tube 5 and the opening are separated. Close the gap. By this water stop treatment, the risk of rainwater or the like entering from the outside to the inside through the sheath guide 13 can be extremely reduced. In place of the caulking process, an O-ring may be sandwiched between the sheath tube guide 13 and the sheath tube 5, or both water stop treatments may be used together.

又、屋外側の鞘管5の他端は外壁2の屋外側に設置されたシステムアジャスタ支え29によって支持されたシステムアジャスタ30に接続される。配管4が通るシステムアジャスタ30は伸縮自在の蛇腹部31を有しており、鞘管5の屋外に露出している部分の長さに適合した高さに伸び縮みできる。又、システムアジャスタ30の下端を受けるピン付オスアダプタ33には継手32を介して配管4が接続されている。このアダプタ33は屋外に設置された給湯器34に連結されていて、給湯器34の温水等が導かれる。   The other end of the outdoor sheath tube 5 is connected to a system adjuster 30 supported by a system adjuster support 29 installed on the outdoor side of the outer wall 2. The system adjuster 30 through which the pipe 4 passes has an expandable / contractible bellows portion 31 and can expand and contract to a height suitable for the length of the portion exposed to the outside of the sheath tube 5. A pipe 4 is connected to a male adapter 33 with a pin that receives the lower end of the system adjuster 30 via a joint 32. The adapter 33 is connected to a water heater 34 installed outdoors, and hot water or the like of the water heater 34 is guided.

以上、説明した壁貫通配管の壁通し具1を用いた配管4及び鞘管5の配設作業によれば、外壁2に対して斜めに設けられた鞘管ガイド13に鞘管5を通すことで、外壁2の壁面に沿うように鞘管5を屋内へと配設する。第1筒部8及び第2筒部17の鉛直方向に沿った幅Dが、鞘管5の外径dより十分大きく形成されているので、鞘管5が無理に折り曲げられて座屈変形を起さない十分に広い空間Sを、第1筒部8及び第2筒部17内に確保できる。また、外壁2に対して斜めに設けられた鞘管ガイド13に鞘管5を通すことで、外壁2の壁面に沿うように鞘管5を屋内へと配設できる。   As described above, according to the arrangement work of the pipe 4 and the sheath pipe 5 using the wall through tool 1 of the wall penetration pipe described above, the sheath pipe 5 is passed through the sheath pipe guide 13 provided obliquely with respect to the outer wall 2. Thus, the sheath tube 5 is disposed indoors along the wall surface of the outer wall 2. Since the width D along the vertical direction of the first tube portion 8 and the second tube portion 17 is formed sufficiently larger than the outer diameter d of the sheath tube 5, the sheath tube 5 is forcibly bent to cause buckling deformation. A sufficiently wide space S that does not occur can be secured in the first tube portion 8 and the second tube portion 17. Further, the sheath tube 5 can be placed indoors along the wall surface of the outer wall 2 by passing the sheath tube 5 through the sheath tube guide 13 provided obliquely with respect to the outer wall 2.

したがって、外壁2の屋内側の狭い壁裏空間内においても鞘管5を無理に折り曲げて座屈変形を起こさせることがない。このため、鞘管5の内部に通して屋外から屋内へと配設する配管4も無理に折り曲げて座屈変形を起こさせることなく、容易に配設できる。さらに、屋外側より配管4を斜め下方に引っ張ることにより、挿入時と同様に鞘管5をガイドとして少ない抵抗で容易に配管4を引き出せるので、こうした配管4の出し入れ操作によって、将来において配管4が老朽化した場合の配管4の更新作業も簡単に行うことができる。   Therefore, even in the narrow wall space on the indoor side of the outer wall 2, the sheath tube 5 is not forcibly bent to cause buckling deformation. For this reason, the pipe 4 that passes through the inside of the sheath pipe 5 and is arranged from the outside to the inside can be easily arranged without forcibly bending and causing buckling deformation. Further, by pulling the pipe 4 obliquely downward from the outdoor side, the pipe 4 can be easily pulled out with less resistance using the sheath pipe 5 as a guide as in the insertion. The work of updating the pipe 4 when it is aged can be easily performed.

又、壁貫通配管の壁通し具1の位置において鞘管5は途切れることなく屋外から屋内へと連続して配設されている。このため、屋内で配管4から水が漏れ出しても鞘管5の内部を伝わって屋外へと排出されるので、屋内への浸水のおそれが低い。しかも、鞘管5及び配管4が外壁2を貫通しており、配管4に対する継手部分は外壁2の屋外側にあるので、漏水し易い継手部分からの漏水があっても屋内への浸水のおそれがない。   Further, the sheath tube 5 is continuously arranged from the outside to the indoor without interruption at the position of the wall threading tool 1 of the wall through pipe. For this reason, even if water leaks out from the pipe 4 indoors, the water travels through the inside of the sheath pipe 5 and is discharged to the outside. And since the sheath pipe 5 and the piping 4 have penetrated the outer wall 2, and the joint part with respect to the pipe 4 exists in the outdoor side of the outer wall 2, even if there is a leak from the joint part which is easy to leak, there is a possibility of flooding indoors There is no.

又、鞘管ガイド13はこの屋内側が屋外側よりも上側に位置するように閉塞部12を斜めに貫通して設けられているので、雨水等が斜め下向きの鞘管ガイド13を通って屋外から屋内へと浸入するおそれが殆どない。加えて、この鞘管ガイド13の屋外側の開口部にコーキング材28等による止水処理を施して鞘管5と開口部との隙間を塞いだので、より一層のこと浸水のおそれがない。   Further, since the sheath guide 13 is provided obliquely through the closed portion 12 so that the indoor side is located above the outdoor side, rainwater or the like passes through the sheath guide 13 obliquely downward from the outside. There is almost no risk of entering indoors. In addition, since the opening on the outdoor side of the sheath tube guide 13 is subjected to water-stopping treatment with the caulking material 28 or the like to close the gap between the sheath tube 5 and the opening, there is no further possibility of flooding.

又、第1、第2フランジ部10、19及びそれらに夫々設けられた止水パッキン14a、14bによって、外壁2の両側から設置穴3を隙間なく挟み込むサンドイッチ構造をとっているので、簡単に止水処理ができると共に、設置穴3と壁通し具1との間の埋め戻し作業等の閉栓処理も不要にでき、施工性がよい。   Also, since the first and second flange portions 10 and 19 and the water-stopping packings 14a and 14b provided on the flange portions 10 and 19 respectively have a sandwich structure in which the installation hole 3 is sandwiched from both sides of the outer wall 2 without gaps, Water treatment can be performed, and plugging processing such as backfilling work between the installation hole 3 and the wall threading tool 1 can be made unnecessary, and workability is good.

又、設置穴3への壁通し具1の取付け作業と、屋内における配管4及び鞘管5の配設作業の順序はどちらが先でも構わない。又、プレハブ住宅の場合には壁通し具1を外壁2に予め取付けておくことができるから、その場合には建築現場での壁通し具1の取付けが不要であり、容易に配設作業を行うことができる。   Further, the order of the work of attaching the wall threading tool 1 to the installation hole 3 and the work of arranging the pipe 4 and the sheath pipe 5 indoors may be first. In the case of a prefabricated house, the wall threading tool 1 can be attached to the outer wall 2 in advance. In this case, the wall threading tool 1 is not required to be installed at the construction site. It can be carried out.

又、壁通し具1は正面から見た形状が上下方向に沿って長い小判形となっていて小型であるため、外壁2に設けられた設置穴3も正面から見た形状を同様の小判形とできるので、大きな円形の穴を外壁2に設ける必要がなく、設置穴3を設けることによる外壁2の強度の低下を抑制できる。   Further, since the shape of the wall threading tool 1 as viewed from the front is an oval shape that is long in the vertical direction and is small, the installation hole 3 provided in the outer wall 2 also has the same oval shape as viewed from the front. Therefore, it is not necessary to provide a large circular hole in the outer wall 2, and a decrease in strength of the outer wall 2 due to the installation hole 3 can be suppressed.

It is in close contact with the outer peripheral surface of the sheath tube 5 and is used to stop water at the sheath tube passage hole 56a. In addition, instead of the O-ring 64, a caulking process may be applied to the sheath tube passage hole 56a portion to constitute a water stop means between the sheath tube guide 54 and the sheath tube 5.

なお、前記構成の壁貫通配管の壁通し具51の具体的な寸法例を挙げると、呼び径13mmの配管4を呼び径28mmの鞘管5とともに、75mmの厚みの外装パネル52に斜めに貫通させる場合、設置穴53の壁貫通角度θは45°とし、設置穴53の穴径は45mm程度とすることが、設置穴53による外装パネル52の強度低下を小さくする上で望ましい。又、以上説明した点以外の構成は前記第1の実施の形態と同じである。   In addition, as an example of a specific dimension of the wall through-hole 51 of the wall through pipe having the above-described configuration, the pipe 4 having a nominal diameter of 13 mm is obliquely penetrated through the outer panel 52 having a thickness of 75 mm together with the sheath pipe 5 having a nominal diameter of 28 mm. In order to reduce the strength reduction of the exterior panel 52 due to the installation hole 53, it is desirable that the wall penetration angle θ of the installation hole 53 is 45 ° and the diameter of the installation hole 53 is about 45 mm. The configuration other than the points described above is the same as that of the first embodiment.

次に、前記構成の壁貫通配管の壁通し具51を用いた配管4及び鞘管5の配設作業を説明する。まず、外装パネル52に壁通し具51を設置する手順を説明する。   Next, the arrangement | positioning operation | work of the piping 4 and the sheath tube 5 using the wall through tool 51 of the wall penetration piping of the said structure is demonstrated. First, the procedure for installing the wall threading tool 51 on the exterior panel 52 will be described.

鞘管ガイド54をその壁押さえ55が嵌合される側の端部を先頭にして、外装パネル52をその内壁面側から外壁面側に向けて斜めに下がるように貫通した設置穴53に前記内壁面側から挿通する。この挿通はフランジ部61が前記内壁面において設置穴53の穴縁に引掛るまで行われ、それにより、鞘管ガイド54が設置穴53を斜めに貫通してそのねじ部62を有した端部が、外装パネル52の外壁面から斜め下向きに突出する。次に、斜め下向きに突出した鞘管ガイド54の前記端部の外周に壁押さえ55を、その止水パッキン63全体が外装パネル52の外面に接するように嵌合させる。最後に、鞘管ガイド54のねじ部62に固定手段としての締付けナット56を螺合して、これを回動操作し締付けることにより、鞘管ガイド54と壁押さえ55とにわたって締付けナット56を設ける。   The casing tube guide 54 is inserted into the installation hole 53 penetrating through the exterior panel 52 from the inner wall surface side toward the outer wall surface side with the end portion on the side where the wall presser 55 is fitted as the head. Insert from the inner wall side. This insertion is performed until the flange portion 61 is caught on the hole edge of the installation hole 53 on the inner wall surface, whereby the sheath tube guide 54 obliquely penetrates the installation hole 53 and has the threaded portion 62. However, it projects obliquely downward from the outer wall surface of the exterior panel 52. Next, a wall presser 55 is fitted to the outer periphery of the end portion of the sheath guide 54 that protrudes obliquely downward so that the entire waterproofing packing 63 contacts the outer surface of the exterior panel 52. Finally, a tightening nut 56 as a fixing means is screwed into the threaded portion 62 of the sheath tube guide 54, and is rotated and tightened to provide the tightening nut 56 over the sheath tube guide 54 and the wall presser 55. .

このナット56の締付けにより、壁押さえ55を鞘管ガイド54の軸方向に沿って外装パネル52の外壁面に押付けて保持する。それにより、フランジ部61と壁押さえ55との間に外装パネル52を挟んだ状態で外装パネル52を斜めに貫通して壁通し具51が設置される。この設置と同時に、外装パネル52の外面と壁押さえ55との間に配置された止水パッキン63が圧縮状態となって、設置穴53と鞘管ガイド54との間への浸水を阻止できる。   By tightening the nut 56, the wall presser 55 is pressed and held against the outer wall surface of the exterior panel 52 along the axial direction of the sheath guide 54. Accordingly, the wall threading tool 51 is installed through the exterior panel 52 obliquely with the exterior panel 52 sandwiched between the flange portion 61 and the wall presser 55. Simultaneously with this installation, the water-stop packing 63 disposed between the outer surface of the exterior panel 52 and the wall presser 55 is in a compressed state, and water intrusion between the installation hole 53 and the sheath guide 54 can be prevented.

前記設置作業において、外装パネル52の外壁面から斜め下向きに突出された鞘管ガイド54の端部に対してこれに嵌合された壁押さえ55は軸方向に摺動可能であり、かつ、壁押さえ55は締付けナット56の締付けにより外装パネル52へ移動されるものであるから、壁押さえ55を軸方向に移動によりこれとフランジ部61との間の距離を調節して壁通し具51を設置できる。すなわち、本実施形態に係る壁通し具51は厚みの異なる種々の外装パネル72への設置に容易に適合できる。   In the installation operation, the wall retainer 55 fitted to the end of the sheath tube guide 54 protruding obliquely downward from the outer wall surface of the exterior panel 52 is slidable in the axial direction, and the wall Since the presser 55 is moved to the exterior panel 52 by tightening the tightening nut 56, the wall passer 51 is installed by adjusting the distance between the wall presser 55 and the flange portion 61 by moving the wall presser 55 in the axial direction. it can. That is, the wall threading tool 51 according to the present embodiment can be easily adapted to be installed on various exterior panels 72 having different thicknesses.

この後には、外装パネル52を斜めに貫通した鞘管ガイド54及び締付けナット56の鞘管通孔56aに外装パネル52の例えば外壁面側から鞘管5を通して、この鞘管5の中間部を外装パネル52に対して斜めに貫通させた後、この鞘管5内に外装パネル52の外壁面側から配管4を挿入することにより、鞘管5内を通して所定の場所に配管4を導いて配設する。この設置状態において、鞘管ガイド54と鞘管5との間の止水を行なう場合には、一旦、締付けナット56を取外してその内側にOリング64を配置させた状態で、再び締付けナット56を締付ければよい。それにより、Oリング64が締付けナット56と鞘管ガイド54の端面との間に挟着されるに伴って弾性変形されて、このOリング64が鞘管5の外周面に密着して、鞘管ガイド54と鞘管5との間の止水が行われる。なお、コーキング処理により止水を行なう場合には、締付けナット56を取外すことなく、その鞘管通孔56aと鞘管5との間にコーキング材を充填することで行なえばよい。   Thereafter, the sheath tube 5 is passed through the sheath tube guide 54 and the sheath tube passage hole 56a of the tightening nut 56 obliquely through the sheath panel 52, for example, from the outer wall surface side of the sheath panel 52, and the intermediate portion of the sheath tube 5 is sheathed. After passing through the panel 52 obliquely, the pipe 4 is inserted into the sheath pipe 5 from the outer wall surface side of the exterior panel 52, thereby leading the pipe 4 to a predetermined place through the sheath pipe 5. To do. In this installed state, when water is shut off between the sheath tube guide 54 and the sheath tube 5, the tightening nut 56 is once again in a state in which the tightening nut 56 is once removed and the O-ring 64 is disposed inside thereof. Can be tightened. As a result, the O-ring 64 is elastically deformed as it is sandwiched between the tightening nut 56 and the end surface of the sheath tube guide 54, and the O-ring 64 comes into close contact with the outer peripheral surface of the sheath tube 5. Water stoppage between the tube guide 54 and the sheath tube 5 is performed. When water is stopped by the caulking process, the caulking material may be filled between the sheath tube through hole 56a and the sheath tube 5 without removing the tightening nut 56.

なお、以上の点以外の接続作業等は前記第1の実施の形態と同じである。又、プレハブ住宅の外装パネル52に対してはその生産段階で予め壁通し具51を装着して置くことができるので、このようにして建築現場に供給する場合には、建築現場では壁通し具51を外装パネル52に設置する作業を要することがなくなり、したがって、建築現場での鞘管5及び配管4の配設作業を速やかに開始することができる。   The connection work other than the above points is the same as in the first embodiment. In addition, since the wall threading tool 51 can be mounted and placed in advance on the exterior panel 52 of the prefabricated house in the production stage, the wall threading tool is used at the construction site when supplying it to the construction site in this way. The operation of installing 51 on the exterior panel 52 is no longer required, and therefore, the disposing operation of the sheath pipe 5 and the pipe 4 at the construction site can be started promptly.

以上説明した壁貫通配管の壁通し具51を用いた配管4及び鞘管5の配設作業によれば、外装パネル52を斜めに貫通して設けられた鞘管ガイド54に鞘管5を通すことで、外装パネル52の内壁面に沿うように鞘管5を屋内へと配設でき、外装パネル52の屋内側の狭い壁裏空間内においても鞘管5を無理に折り曲げて座屈変形を起こさせることがない。このため、鞘管5の内部に通して屋外から屋内へと配設する配管4も無理に折り曲げて座屈変形を起こさせることなく、容易に配設できる。さらに、屋外側より配管4を斜め下方に引っ張ることにより、挿入時と同様に鞘管5をガイドとして少ない抵抗で容易に配管4を引き出せるので、こうした配管4の出し入れ操作によって、将来において配管4が老朽化した場合の配管4の更新作業も簡単に行うことができる。   According to the operation of arranging the pipe 4 and the sheath pipe 5 using the wall threading tool 51 of the wall through pipe described above, the sheath pipe 5 is passed through the sheath pipe guide 54 provided obliquely through the exterior panel 52. Thus, the sheath tube 5 can be disposed indoors along the inner wall surface of the exterior panel 52, and the sheath tube 5 is forcibly bent even in the narrow wall space on the indoor side of the exterior panel 52 to cause buckling deformation. There is no waking. For this reason, the pipe 4 that passes through the inside of the sheath pipe 5 and is arranged from the outside to the inside can be easily arranged without forcibly bending and causing buckling deformation. Further, by pulling the pipe 4 obliquely downward from the outdoor side, the pipe 4 can be easily pulled out with less resistance using the sheath pipe 5 as a guide as in the insertion. The work of updating the pipe 4 when it is aged can be easily performed.

しかも、前記壁通し具51の採用により、鞘管5を外装パネル52の位置において途切れることなく屋外から屋内へと連続して配設できるため、屋内で配管4から水が漏れ出しても鞘管5の内部を伝わって屋外へと排出され、屋内への浸水のおそれが低いとともに、外装パネル52を貫通した配管4に対する継手部分は外装パネル52の屋外側にあるので、漏水し易い前記継手部分からの漏水があっても屋内へ浸入するおそれがない。   Moreover, since the sheath tube 5 can be continuously arranged from the outdoor to the indoor without being interrupted at the position of the exterior panel 52 by employing the wall threading tool 51, the sheath tube can be used even if water leaks from the piping 4 indoors. 5, which is discharged to the outside through the inside of the interior 5 and has a low risk of flooding indoors, and since the joint portion for the pipe 4 penetrating the exterior panel 52 is on the exterior side of the exterior panel 52, the joint portion easily leaks. There is no risk of intrusion even if water leaks from

又、鞘管ガイド54は屋外側に向けて斜めに下がるように傾斜して外装パネル52を貫通して設けられているので、雨水等が斜めの鞘管ガイド54を通って屋外から屋内へと浸入するおそれが殆どない。加えて、この鞘管ガイド54の屋外側の開口部にOリング64等による止水処理を施したので、より一層のこと浸水のおそれがない。   Further, since the sheath tube guide 54 is provided so as to be inclined obliquely downward toward the outdoor side and penetrates the exterior panel 52, rainwater or the like passes through the oblique sheath tube guide 54 from the outdoor to the indoor. There is almost no risk of intrusion. In addition, since the water stop treatment by the O-ring 64 and the like is performed on the outdoor side opening of the sheath tube guide 54, there is no further risk of flooding.

更に、この壁通し具51は、鞘管ガイド54のフランジ部61と壁押さえ55とで、外装パネル52を厚み方向から挟み込むサンドイッチ構造をとっているので、止水パッキン63を用いて簡単に止水処理ができると共に、設置穴53と壁通し具51との間の埋め戻し作業等の閉栓処理も不要にでき、施工性がよい。その上、前記サンドイッチ構造において外装パネル52を挟み込む力を与える締付けナット56は外装パネル52に対して進退可能であるから、外装パネル52の厚み変化に対応して壁通し具51を取付けて用いることができる。又、前記サンドイッチ構造により、鞘管ガイド54に新規に配管4を通すときは勿論のこと、老朽化した配管4を新品の配管と交換するときにおいても、配管4や鞘管5を鞘管ガイド54に通す際等に加わる操作力を、配管等を押し込んだり、引き出したりする操作方向の上流側において外装パネル52に引掛かっているフランジ部61又は壁押さえ55に波及させて外装パネル52で分散して支持できる。よって、壁通し具51が外装パネル52から不用意に外れたり、外装パネル52とこれを挟んだフランジ部61及び壁押さえ55との接合が緩むことがなく、したがって、防水性が損なわれるおそれを低くできる。   Further, the wall threading tool 51 has a sandwich structure in which the outer panel 52 is sandwiched from the thickness direction by the flange portion 61 of the sheath tube guide 54 and the wall presser 55, so that it can be easily stopped using the water stop packing 63. Water treatment can be performed, and plugging treatment such as backfilling work between the installation hole 53 and the wall threading tool 51 can be eliminated, and workability is good. In addition, since the tightening nut 56 for applying a force for sandwiching the exterior panel 52 in the sandwich structure can be advanced and retracted with respect to the exterior panel 52, the wall threading tool 51 is attached and used in accordance with the thickness change of the exterior panel 52. Can do. In addition, due to the sandwich structure, not only when the pipe 4 is newly passed through the sheath guide 54, but also when the old pipe 4 is replaced with a new pipe, the pipe 4 or the sheath pipe 5 is replaced with the sheath guide. 54, the operating force applied when passing through 54, etc. is spread by the outer panel 52 by spreading to the flange 61 or the wall holder 55 hooked to the outer panel 52 on the upstream side in the operation direction of pushing in or pulling out the piping or the like. Can be supported. Therefore, the wall threading tool 51 is not inadvertently detached from the exterior panel 52, and the joint between the exterior panel 52 and the flange portion 61 and the wall presser 55 sandwiching the exterior panel 52 is not loosened. Can be lowered.

又、前記構成の壁通し具51の採用により、大きな円形の穴を外装パネル52に設ける必要がなく、斜めの設置穴53を設けることに伴う外装パネル52の強度の低下を抑制できる。しかも、この第5実施形態では、前記サンドイッチ構造の採用とその締付けを行なう固定手段として締付けナット56を用いたから、外装パネル52への固定に要する固定部品と手間が少なく、しかも、締付け操作も回動するだけであって容易であるので、外装パネル52への壁通し具51の設置作業性がよい。しかし、この第5実施形態における固定手段としては、締付けナットに代えて、鞘管ガイド54の外面に予め回動可能に取付けられているレバーを操作することにより、このレバーのカム部で壁押さえ55を外装パネル52側に押圧移動させて締付け力(外装パネル52をフランジ部61と壁押さえ55とで挟み付ける力)を与えるレバー式等のクランプを採用することもできる。   Further, by adopting the wall threading tool 51 having the above-described configuration, it is not necessary to provide a large circular hole in the exterior panel 52, and a decrease in strength of the exterior panel 52 due to the provision of the oblique installation hole 53 can be suppressed. Moreover, in the fifth embodiment, since the tightening nut 56 is used as a fixing means for adopting and tightening the sandwich structure, there are few fixing parts and labor required for fixing to the exterior panel 52, and the tightening operation is also reduced. Since it only moves and is easy, the installation workability of the wall threading tool 51 to the exterior panel 52 is good. However, as a fixing means in the fifth embodiment, instead of a tightening nut, a lever that is attached to the outer surface of the sheath tube guide 54 in advance so as to be pivotable is operated, so that a wall pressing is performed by the cam portion of this lever. It is also possible to employ a lever-type clamp that presses and moves 55 to the exterior panel 52 side to give a tightening force (a force to sandwich the exterior panel 52 between the flange portion 61 and the wall presser 55).

(実施形態6)
次に、図12〜図14を参照して本発明の第6の実施の形態に係る壁貫通配管の壁通し具71を説明する。なお、以下説明する壁通し具71及び壁の設置穴73以外は、図12〜図14に示されない部分を含めて前記第1の実施の形態と同じであるから、鞘管及び配管等の同一部分についての説明は、第1の実施の形態と同じ符号を付してその説明を省略し、異なる部分についてのみ説明する。
(Embodiment 6)
Next, a wall threading tool 71 for a wall through pipe according to a sixth embodiment of the present invention will be described with reference to FIGS. In addition, since it is the same as that of the said 1st Embodiment including the part which is not shown by FIGS. 12-14 except the wall threading tool 71 and the wall installation hole 73 which are demonstrated below, it is the same, such as a sheath pipe and piping. In the description of the parts, the same reference numerals as those in the first embodiment are attached and the description thereof is omitted, and only different parts will be described.

この第6の実施形態に係る壁通し具71が設置される住宅の壁、本実施形態の場合にはプレハブ工法により作られる住宅の外装パネル(外壁)72の所定位置には斜めに貫通する断面円形の設置穴73が開けられている。この穴73は屋内側から屋外側に行くにしたがって次第に下がるように傾斜しており、その壁貫通角度θは45°である。壁通し具71は、鞘管ガイド74と、壁押さえ75とを具備している。   Section of the wall of the house where the wall threading tool 71 according to the sixth embodiment is installed, in the case of this embodiment, obliquely penetrates to a predetermined position of the exterior panel (outer wall) 72 of the house made by the prefabricated construction method A circular installation hole 73 is formed. The hole 73 is inclined so as to gradually fall from the indoor side to the outdoor side, and the wall penetration angle θ is 45 °. The wall threading tool 71 includes a sheath tube guide 74 and a wall press 75.

金属又は硬質合成樹脂製の鞘管ガイド74は、外装パネル72の厚みよりも長い円筒からなるガイド筒部74aの一端部外周に、周方向に連続して円形をなす(図13参照)フランジ部74bを一体に設けて形成されている。ガイド筒部74aの外径は設置穴73の径に略等しい。フランジ部74bはガイド筒部74aの軸線に対して交差する方向に沿って外側に張り出して設けられており、その複数箇所には図示しないねじ通し穴が開けられている。このフランジ部74bが連なるガイド筒部74aの一端部の内周面にはテーパ面76が設けられている。このテーパ面76によってガイド筒部74aの内径はフランジ部74b側程次第に大きくなっている。   A metal or hard synthetic resin sheath guide 74 is formed in a circular shape continuously in the circumferential direction on the outer periphery of one end of a guide cylinder 74a made of a cylinder longer than the thickness of the exterior panel 72 (see FIG. 13). 74b is integrally formed. The outer diameter of the guide tube portion 74 a is substantially equal to the diameter of the installation hole 73. The flange portion 74b is provided so as to project outward along the direction intersecting the axis of the guide tube portion 74a, and screw holes (not shown) are formed at a plurality of locations. A tapered surface 76 is provided on the inner peripheral surface of one end portion of the guide tube portion 74a connected to the flange portion 74b. Due to the taper surface 76, the inner diameter of the guide tube portion 74a gradually increases toward the flange portion 74b.

金属又は硬質合成樹脂製の壁押さえ75は、外装パネル72の外面から斜めに突出した部分の外周に摺動可能に嵌合して設けられている。この壁押さえ75はガイド筒部74aの軸方向に少なくとも摺動可能であればよい。例えば、鞘管ガイド74の前記突出部外周面と壁押さえ75の内周面との夫々に軸方向に延びる1以上の凹部又は凸部を設けて、これらを壁通し具71の軸方向に沿って摺動可能に凹凸嵌合させて、ガイド筒部74aに対して壁押さえ75を回り止めしてもよい。   A wall retainer 75 made of metal or hard synthetic resin is provided so as to be slidably fitted to the outer periphery of a portion protruding obliquely from the outer surface of the exterior panel 72. The wall press 75 may be slidable at least in the axial direction of the guide tube portion 74a. For example, one or more recesses or projections extending in the axial direction are provided on the outer peripheral surface of the protruding portion of the sheath guide 74 and the inner peripheral surface of the wall retainer 75, and these are provided along the axial direction of the wall threading tool 71. The wall presser 75 may be prevented from rotating with respect to the guide tube portion 74a by being slidably unevenly fitted.

壁押さえ75は外装パネル72の壁面に沿うフランジ部75aを一体に有している。このフランジ部75aは円形をなして(図14参照)壁押さえ75の軸線に対して交差する方向に沿って外側に張り出して設けられており、その複数箇所には図示しないねじ通し穴が開けられている。フランジ部75aにはこれと同形状の止水パッキン77が接着されている。このパッキン77は、設置穴73と鞘管ガイド74との間の止水手段として用いられるものであるが、外装パネル72の外面に接着してもよく、或いは、フランジ部74b及び外装パネル72の外面のいずれにも接着することなく、これらの間に挟んで設けてもよい。なお、この止水パッキン77に代えてコーキング処理をフランジ部75aと外装パネル72の外面とにわたって施してもよい。   The wall retainer 75 integrally has a flange portion 75 a along the wall surface of the exterior panel 72. The flange portion 75a has a circular shape (see FIG. 14) and is provided to project outward along a direction intersecting the axis of the wall retainer 75. Screw holes (not shown) are formed at a plurality of locations. ing. A waterproof seal 77 having the same shape as this is bonded to the flange portion 75a. The packing 77 is used as a water stop means between the installation hole 73 and the sheath tube guide 74, but may be adhered to the outer surface of the exterior panel 72, or the flange portion 74 b and the exterior panel 72. You may pinch | interpose between these, without adhering to either of outer surfaces. Note that, instead of the water-stopping packing 77, a caulking process may be performed over the flange portion 75a and the outer surface of the exterior panel 72.

次に、前記構成の壁貫通配管の壁通し具71を用いた配管4及び鞘管5の配設作業を説明する。まず、外装パネル72に壁通し具71を設置する手順を説明する。   Next, the arrangement | positioning operation | work of the piping 4 and the sheath tube 5 using the wall threading tool 71 of the wall penetration piping of the said structure is demonstrated. First, a procedure for installing the wall threading tool 71 on the exterior panel 72 will be described.

フランジ部74bがない方のガイド筒部74aの端部を先頭にして鞘管ガイド74を、外装パネル72の屋内側から設置穴73に挿通させる。この挿通はフランジ部74bが外装パネル72の内壁面において設置穴73の穴縁に引っ掛るまで行われ、それにより、ガイド筒部74aは屋内側から屋外側に行くにしたがって外装パネル72を斜め下向きに貫通する。この状態で、フランジ部74bの図示しないねじ通し穴に通されて外装パネル72にねじ込まれるねじ78を夫々締付けて、鞘管ガイド74を外装パネル72に固定する。次に、外装パネル72の外壁面から斜め下向きに突出された鞘管ガイド74の端部に、壁押さえ75をその止水パッキン77全体が外装パネル72の外壁面に接するように嵌合させる。最後に、この壁押さえ75のフランジ部75aの図示しないねじ通し穴に通されて外装パネル72にねじ込まれるねじ79を夫々締付けて、壁押さえ75を外装パネル72に固定する。   The sheath tube guide 74 is inserted into the installation hole 73 from the indoor side of the exterior panel 72 with the end portion of the guide tube portion 74a without the flange portion 74b as the head. This insertion is performed until the flange portion 74b is caught by the hole edge of the installation hole 73 on the inner wall surface of the exterior panel 72, so that the guide tube portion 74a faces the exterior panel 72 obliquely downward as it goes from the indoor side to the outdoor side. To penetrate. In this state, screws 78 that are passed through screw holes (not shown) of the flange portion 74 b and screwed into the exterior panel 72 are tightened to fix the sheath tube guide 74 to the exterior panel 72. Next, the wall presser 75 is fitted to the end portion of the sheath tube guide 74 projecting obliquely downward from the outer wall surface of the exterior panel 72 so that the entire waterproofing packing 77 is in contact with the outer wall surface of the exterior panel 72. Finally, screws 79 that are passed through screw holes (not shown) of the flange portions 75 a of the wall press 75 and screwed into the exterior panel 72 are tightened to fix the wall press 75 to the exterior panel 72.

以上の手順により、フランジ部74b、75a間に外装パネル72を挟んだ状態でこのパネル72を斜めに貫通して壁通し具71が設置される。この設置と同時に、外装パネル72の外壁面と壁押さえ75との間に挟まれた止水パッキン77が圧縮状態となって、設置穴73と鞘管ガイド74との間への屋外からの浸水を防止できる。   Through the above procedure, the wall threading tool 71 is installed through the panel 72 obliquely with the exterior panel 72 sandwiched between the flange portions 74b and 75a. Simultaneously with this installation, the water-stopping packing 77 sandwiched between the outer wall surface of the exterior panel 72 and the wall retainer 75 is in a compressed state, so that water can be immersed from the outside between the installation hole 73 and the sheath guide 74. Can be prevented.

前記設置作業において、外装パネル72の外壁面から斜め下向きに突出された鞘管ガイド74の端部に対してこれに嵌合された壁押さえ75は軸方向に摺動可能であり、かつ、壁押さえ75は外装パネル72にねじ止めされるものであるから、外装パネル72の厚みが例えば75mm又は100mmのいずれであっても壁押さえ75を軸方向に動かして、既述のように壁通し具71を設置できる。すなわち、本実施形態に係る壁通し具71は厚みの異なる種々の外装パネル72への設置に容易に適合できる。   In the installation operation, the wall retainer 75 fitted to the end of the sheath guide 74 protruding obliquely downward from the outer wall surface of the exterior panel 72 is slidable in the axial direction, and the wall Since the retainer 75 is screwed to the exterior panel 72, the wall retainer 75 is moved in the axial direction to move the wall retainer 75 as described above regardless of whether the exterior panel 72 has a thickness of, for example, 75 mm or 100 mm. 71 can be installed. That is, the wall threading tool 71 according to this embodiment can be easily adapted to be installed on various exterior panels 72 having different thicknesses.

この後には、外装パネル72を斜めに貫通した鞘管ガイド74のガイド筒部74aに外装パネル72の例えば内壁面側から鞘管5を通して、この鞘管5を外装パネル72に対して斜めに貫通させた後、この鞘管5内に外装パネル72の外面側から配管4を挿入することにより、鞘管5内を通して所定の場所に配管4を導いて配設する。   Thereafter, the sheath tube 5 is passed through the sheath tube 5 obliquely with respect to the exterior panel 72 through the guide tube portion 74a of the sheath tube guide 74 that obliquely penetrates the exterior panel 72 from the inner wall surface side of the exterior panel 72, for example. Then, the pipe 4 is inserted into the sheath pipe 5 from the outer surface side of the exterior panel 72, thereby leading the pipe 4 to a predetermined place through the sheath pipe 5.

この場合、ガイド筒部74aの屋内側端部にはテーパ面76を設けてあり、屋内側から鞘管5を壁通し具71に貫通する際の入口が広くなっているだけではなく、ガイド筒部74aは途中に継ぎ目がなく外装パネル72を貫通する斜めの直管であるから、この筒部74aへの鞘管5の挿通(挿入方向は問わない)に際して鞘管5がガイド筒部74aに引掛る恐れがなく、したがって、鞘管5の挿通作業性がよい。この設置状態において、鞘管ガイド74と鞘管5との間の止水を必要とする場合には、ガイド筒部74aの屋外に突出した端部と鞘管5とにわたって図示しないコーキング材を充填することで行なえばよい。   In this case, a tapered surface 76 is provided at the indoor side end portion of the guide tube portion 74a, and not only the entrance for penetrating the sheath tube 5 from the indoor side to the wall threading tool 71 is widened, but also the guide tube. Since the portion 74a is an oblique straight tube that has no seam in the middle and penetrates the exterior panel 72, the sheath tube 5 is inserted into the guide tube portion 74a when the sheath tube 5 is inserted into the tube portion 74a (regardless of the insertion direction). There is no fear of being caught, and therefore the workability of inserting the sheath tube 5 is good. In this installed state, when water stoppage between the sheath tube guide 74 and the sheath tube 5 is required, a caulking material (not shown) is filled over the end portion of the guide tube portion 74a protruding to the outside and the sheath tube 5. To do so.

なお、以上の点以外の接続作業等は前記第1の実施の形態と同じである。又、プレハブ住宅の外装パネル72に対してはその生産段階で予め壁通し具71を装着して置くことができるので、このようにして建築現場に供給する場合には、建築現場では壁通し具71を外装パネル72に設置する作業を要することがなくなり、したがって、建築現場での鞘管5及び配管4の配設作業を速やかに開始させることができる。   The connection work other than the above points is the same as in the first embodiment. In addition, since the wall threading tool 71 can be mounted and placed in advance on the exterior panel 72 of the prefabricated house in the production stage, the wall threading tool is used at the construction site when supplying it to the construction site in this way. The operation of installing 71 on the exterior panel 72 is not required, and therefore the operation of arranging the sheath tube 5 and the pipe 4 at the construction site can be started quickly.

以上説明した壁貫通配管の壁通し具71を用いた配管4及び鞘管5の配設作業によれば、外装パネル72を斜めに貫通して設けられた鞘管ガイド74に鞘管5を通すことで、外装パネル72の内壁面に沿うように鞘管5を屋内へと配設でき、外装パネル72の屋内側の狭い壁裏空間内においても鞘管5を無理に折り曲げて座屈変形を起こさせることがない。このため、鞘管5の内部に通して屋外から屋内へと配設する配管4も無理に折り曲げて座屈変形を起こさせることなく、容易に配設できる。さらに、屋外側より配管4を斜め下方に引っ張ることにより、挿入時と同様に鞘管5をガイドとして少ない抵抗で容易に配管4を引き出せるので、こうした配管4の出し入れ操作によって、将来において配管4が老朽化した場合の配管4の更新作業も簡単に行うことができる。   According to the arrangement work of the pipe 4 and the sheath pipe 5 using the wall threading tool 71 of the wall through pipe described above, the sheath pipe 5 is passed through the sheath pipe guide 74 provided obliquely through the exterior panel 72. Thus, the sheath tube 5 can be disposed indoors along the inner wall surface of the exterior panel 72, and the sheath tube 5 is forcibly bent even in the narrow wall space on the indoor side of the exterior panel 72 to cause buckling deformation. There is no waking. For this reason, the pipe 4 that passes through the inside of the sheath pipe 5 and is arranged from the outside to the inside can be easily arranged without forcibly bending and causing buckling deformation. Further, by pulling the pipe 4 obliquely downward from the outdoor side, the pipe 4 can be easily pulled out with less resistance using the sheath pipe 5 as a guide as in the insertion. The work of updating the pipe 4 when it is aged can be easily performed.

しかも、前記壁通し具71の採用により、鞘管5を外装パネル72の位置において途切れることなく屋外から屋内へと連続して配設できるため、屋内で配管4から水が漏れ出しても鞘管5の内部を伝わって屋外へと排出され、屋内への浸水のおそれが低いとともに、外装パネル72を貫通した配管4に対する継手部分は外装パネル72の屋外側にあるので、漏水し易い前記継手部分からの漏水があっても屋内へ浸水するおそれがない。   Moreover, since the sheath tube 5 can be continuously arranged from the outdoor to the indoor without being interrupted at the position of the exterior panel 72 by employing the wall threading tool 71, the sheath tube can be used even if water leaks from the piping 4 indoors. 5, which is discharged to the outside through the inside of the interior 5 and has a low risk of flooding indoors, and since the joint portion for the pipe 4 penetrating the exterior panel 72 is on the exterior side of the exterior panel 72, the joint portion easily leaks. There is no risk of flooding indoors even if water leaks from the water.

又、鞘管ガイド74は屋外側に向けて斜めに下がるように傾斜して外装パネル72を貫通して設けられているので、雨水等が斜めの鞘管ガイド74を通って屋外から屋内へと浸入するおそれが殆どない。   Further, since the sheath tube guide 74 is provided so as to be inclined obliquely downward toward the outdoor side and penetrates the exterior panel 72, rainwater or the like passes through the oblique sheath tube guide 74 from the outdoor to the indoor. There is almost no risk of intrusion.

更に、この壁通し具71は、鞘管ガイド74のフランジ部74bと壁押さえ75のフランジ部75aとで、外装パネル72を厚み方向から挟み込むサンドイッチ構造をとっているので、止水パッキン77を用いて簡単に止水処理ができると共に、設置穴73と壁通し具71との間の埋め戻し作業等の閉栓処理も不要にでき、施工性がよい。その上、前記サンドイッチ構造により、鞘管ガイド74に新規に配管4を通すときは勿論のこと、老朽化した配管4を新品の配管と交換するときにおいても、配管4や鞘管5を鞘管ガイド74に通す際等に加わる操作力を、配管等を押し込んだり、引き出したりする操作方向の上流側において外装パネル72に引掛かっているフランジ部74b又は75aに波及させて外装パネル72で分散して支持できる。よって、壁通し具71が外装パネル72から不用意に外れたり、外装パネル72とこれを挟んだフランジ部74b又は75aとの接合が緩むことがなく、したがって、防水性が損なわれるおそれを低くできる。   Further, since the wall threading tool 71 has a sandwich structure in which the outer panel 72 is sandwiched from the thickness direction by the flange portion 74b of the sheath tube guide 74 and the flange portion 75a of the wall retainer 75, the water stop packing 77 is used. Thus, the water stop process can be easily performed, and the plugging process such as the backfilling operation between the installation hole 73 and the wall threading tool 71 can be omitted, and the workability is good. Moreover, due to the sandwich structure, not only when the pipe 4 is newly passed through the sheath guide 74, but also when the aged pipe 4 is replaced with a new pipe, the pipe 4 and the sheath pipe 5 are replaced with the sheath pipe. The operating force applied when passing through the guide 74 and the like is spread by the exterior panel 72 by spreading to the flange portion 74b or 75a hooked to the exterior panel 72 on the upstream side in the operation direction of pushing in or pulling out the piping or the like. I can support it. Therefore, the wall threading tool 71 is not inadvertently detached from the exterior panel 72, or the joint between the exterior panel 72 and the flange portion 74b or 75a sandwiching the exterior panel 72 is not loosened. .

又、前記構成の壁通し具71の採用により、大きな円形の穴を外装パネル72に設ける必要がなく、斜めの設置穴73を設けることに伴う外装パネル72の強度の低下を抑制できる。しかも、この第6実施形態に係る壁通し具71は、その構成部品が二部品で済むので、構造が簡単であり、安価に提供できるとともに、その外装パネル72への固定も通常のねじ止め作業により容易に行なうことができる。   Further, by adopting the wall threading tool 71 having the above-described configuration, it is not necessary to provide a large circular hole in the exterior panel 72, and a decrease in strength of the exterior panel 72 due to the provision of the oblique installation hole 73 can be suppressed. Moreover, since the wall threading tool 71 according to the sixth embodiment requires only two components, the structure is simple and can be provided at a low cost, and the fixing to the exterior panel 72 is also a normal screwing operation. This can be done easily.

(実施形態7)
次に、図15〜図17を参照して本発明の第7の実施の形態に係る壁貫通配管の壁通し具81を説明する。なお、以下説明する壁通し具81及び壁の設置穴83以外は、図15〜図17に示されない部分を含めて前記第1の実施の形態と同じであるから、鞘管及び配管等の同一部分についての説明は、第1の実施の形態と同じ符号を付してその説明を省略し、異なる部分についてのみ説明する。
(Embodiment 7)
Next, a wall threading tool 81 for a wall through pipe according to a seventh embodiment of the present invention will be described with reference to FIGS. In addition, since it is the same as that of the said 1st Embodiment including the part which is not shown by FIGS. 15-17 except the wall threading tool 81 and the wall installation hole 83 which are demonstrated below, it is the same, such as a sheath pipe and piping. In the description of the parts, the same reference numerals as those in the first embodiment are attached and the description thereof is omitted, and only different parts will be described.

この第7の実施形態に係る壁通し具81が設置される住宅の壁、本実施形態の場合にはプレハブ工法により作られる住宅の外装パネル(外壁)82の所定位置には斜めに貫通する断面円形の設置穴83が開けられている。この穴83は屋内側から屋外側に行くにしたがって次第に下がるように傾斜しており、その壁貫通角度θは45°である。壁通し具81は、第1、第2の鞘管ガイド84、85と、第1引掛り部86と、複数の第2引掛り部87〜89とを具備している。   Section of the wall of the house where the wall threading tool 81 according to the seventh embodiment is installed, in the case of this embodiment, obliquely penetrating to a predetermined position of the exterior panel (outer wall) 82 of the house made by the prefabricated construction method A circular installation hole 83 is formed. The hole 83 is inclined so as to gradually fall from the indoor side to the outdoor side, and the wall penetration angle θ is 45 °. The wall threading tool 81 includes first and second sheath tube guides 84 and 85, a first hooking portion 86, and a plurality of second hooking portions 87 to 89.

金属又は硬質合成樹脂製の第1鞘管ガイド84は、外装パネル82の厚みよりも短い円筒からなるガイド筒部84aの一端部外周に、周方向に連続して円形をなす(図16参照)フランジ部84bを一体に設けて形成されている。ガイド筒部84aの外径は設置穴83の径よりも小さい。フランジ部84bはガイド筒部84aの軸線に対して交差する方向に沿って外側に張り出して設けられており、その複数箇所には図示しないねじ通し穴が開けられている。   The first sheath tube guide 84 made of metal or hard synthetic resin forms a circular shape continuously in the circumferential direction on the outer periphery of one end of the guide tube portion 84a made of a cylinder shorter than the thickness of the exterior panel 82 (see FIG. 16). The flange portion 84b is integrally formed. The outer diameter of the guide tube portion 84 a is smaller than the diameter of the installation hole 83. The flange portion 84b is provided so as to project outward along a direction intersecting the axis of the guide tube portion 84a, and screw holes (not shown) are formed at a plurality of locations.

同様に、金属又は硬質合成樹脂製の第2鞘管ガイド85も、外装パネル82の厚みよりも短い円筒からなるガイド筒部85aの一端部外周に、周方向に連続して円形をなす(図17参照)フランジ部85bを一体に設けて形成されている。ガイド筒部85aは、前記ガイド筒部84aよりも大径であるとともに、その外径は設置穴83の径に略等しく、又、ガイド筒部85aの先端部内周面にはテーパ面が設けられている。前記両ガイド筒部84a、85aは設置穴83内において互いに嵌合されるようになっている。フランジ部85bはガイド筒部85aの軸線に対して交差する方向に沿って外側に張り出して設けられており、その複数箇所には図示しないねじ通し穴が開けられている。   Similarly, the second sheath tube guide 85 made of metal or hard synthetic resin also has a circular shape continuously in the circumferential direction on the outer periphery of one end portion of the guide tube portion 85a formed of a cylinder shorter than the thickness of the exterior panel 82 (see FIG. 17) The flange portion 85b is integrally formed. The guide tube portion 85a has a larger diameter than the guide tube portion 84a, the outer diameter thereof is substantially equal to the diameter of the installation hole 83, and a tapered surface is provided on the inner peripheral surface of the distal end portion of the guide tube portion 85a. ing. The guide tube portions 84a and 85a are fitted in the installation hole 83. The flange portion 85b is provided so as to project outward along a direction intersecting the axis of the guide tube portion 85a, and screw holes (not shown) are formed at a plurality of locations.

第1引掛り部86は、第1鞘管ガイド84に対する第2鞘管ガイド85の嵌合部、つまり、ガイド筒部85aの端部内周面に、その周方向に連続して一体に設けられており、例えば断面三角形状の突条により形成されている。この第1引掛り部86に係脱可能な複数の第2引掛り部87〜89は、第2鞘管ガイド85に対する第1鞘管ガイド84の嵌合部、つまり、ガイド筒部84aの外周面に、その周方向に連続して一体に設けられており、例えば断面三角形状の突条により形成されている。各第2引掛り部87〜89はガイド筒部84aの軸方向に違いに離間して間隔的に設けられている。   The first hooking portion 86 is integrally provided continuously in the circumferential direction on the fitting portion of the second sheath tube guide 85 with respect to the first sheath tube guide 84, that is, on the inner peripheral surface of the end portion of the guide tube portion 85a. For example, it is formed by a protrusion having a triangular cross section. The plurality of second hook portions 87 to 89 that can be engaged with and disengaged from the first hook portion 86 are fitting portions of the first sheath tube guide 84 with respect to the second sheath tube guide 85, that is, the outer periphery of the guide tube portion 84a. It is provided on the surface continuously and integrally in the circumferential direction, and is formed by, for example, a protrusion having a triangular cross section. The second hooks 87 to 89 are spaced apart from each other in the axial direction of the guide tube portion 84a.

これら第2引掛り部87〜89は、外装パネル82の厚みに対応して設けられており、それが第1引掛り部86に引掛った時に、それに応じた両鞘管ガイド84、85の嵌合深さを得て異なる厚みの外装パネル82の夫々適合して壁通し具81が組立てられるようになっている。   These 2nd hook parts 87-89 are provided corresponding to the thickness of exterior panel 82, and when it catches on the 1st hook part 86, both sheath guides 84 and 85 according to it are corresponding. The wall threading tool 81 is assembled by obtaining the fitting depth and adapting the exterior panels 82 having different thicknesses.

つまり、プレハブ住宅の外装パネル82には厚みが異なる数種類のものが用意されていて、その中からいずれかが選択して使用されるものであり、最大厚さ(例えば100mm)の外装パネル82への適用においては、図15のように第1引掛り部86と第2引掛り部89とを引掛けることにより壁通し具81の長さを延ばして適合させ、最小厚さ(例えば75mm)の外装パネル82への適用においては、第1引掛り部86と第2引掛り部87とを引掛けることにより壁通し具81の長さを縮めて適合させ、又、これらの中間厚さの外装パネル82への適用においては、第1引掛り部86と第2引掛り部87とを引掛けることにより壁通し具81の長さを適合させることができる。すなわち、本実施形態に係る壁通し具81は厚みの異なる種々の外装パネル82への設置に容易に適合できる。   In other words, several types of prefabricated housing exterior panels 82 with different thicknesses are prepared, and one of them is selected and used. To the exterior panel 82 having the maximum thickness (for example, 100 mm). 15, the length of the wall threading tool 81 is extended and adapted by hooking the first hooking portion 86 and the second hooking portion 89 as shown in FIG. 15, and the minimum thickness (for example, 75 mm) is applied. In application to the exterior panel 82, the first hook portion 86 and the second hook portion 87 are hooked to reduce the length of the wall threading tool 81, and the outer thickness of these intermediate thicknesses is adapted. In application to the panel 82, the length of the wall threading tool 81 can be adapted by hooking the first hook portion 86 and the second hook portion 87. That is, the wall threading tool 81 according to this embodiment can be easily adapted to be installed on various exterior panels 82 having different thicknesses.

なお、こうした複数段階の壁厚への適合機能は必須ではなく、第1、第2引掛り部は少なくとも一つあればよいとともに、これらの引掛り構造としては第1、第2引掛り部の双方が本実施形態のような突起ではなく、一方が突条で、他方がそれに対応する形状の溝条で形成してもよい。しかし、本実施形態のように断面三角形状の突条とした場合には、それらの斜面によって第1、第2引掛り部の係脱が円滑であるだけではなく、両ガイド筒部84a、85aの嵌合における抵抗を引掛り部の係合位置だけに制限できる点で優れている。なお、これらの係脱に際しては両ガイド筒部84a、85aが多少の弾性変形を伴う。   It should be noted that such a function of adapting to a plurality of wall thicknesses is not essential, and at least one of the first and second hooks is sufficient, and these hooking structures include those of the first and second hooks. Both of them may be formed by not only the protrusions as in the present embodiment but one of the protrusions and the other of the corresponding grooves. However, in the case where the protrusion has a triangular cross section as in the present embodiment, not only the first and second hook portions are smoothly engaged and disengaged by the inclined surfaces, but also the two guide tube portions 84a and 85a It is excellent in that the resistance in fitting can be limited only to the engaging position of the catching portion. Note that when engaging and disengaging these, both guide tube portions 84a and 85a are accompanied by some elastic deformation.

次に、前記構成の壁貫通配管の壁通し具81を用いた配管4及び鞘管5の配設作業を説明する。まず、外装パネル82に壁通し具81を設置する手順を説明する。   Next, the arrangement | positioning operation | work of the piping 4 and the sheath tube 5 using the wall through tool 81 of the wall penetration piping of the said structure is demonstrated. First, a procedure for installing the wall threading tool 81 on the exterior panel 82 will be described.

フランジ部84bがない方のガイド筒部84aの端部を先頭にして第1鞘管ガイド84を、外装パネル82の屋内側から設置穴83に挿入させる。この挿入はフランジ部84bが外装パネル82の内壁面において設置穴83の穴縁に引っ掛るまで行われ、それにより、ガイド筒部84aは屋内側から屋外側に行くにしたがって外装パネル82を斜め下向きにとなる姿勢で設置穴83内に収容される。この状態で、フランジ部84bの図示しないねじ通し穴に通されて外装パネル82にねじ込まれるねじ90を夫々締付けて、第1鞘管ガイド84を外装パネル82に固定する。この設置状態において、ガイド筒部84aの外周面と設置穴83の内周面とは接触しておらず、これらの間には図15に示されるように空隙gが設けられる。   The first sheath tube guide 84 is inserted into the installation hole 83 from the indoor side of the exterior panel 82 with the end of the guide tube portion 84a without the flange portion 84b as the head. This insertion is performed until the flange portion 84b is caught on the hole edge of the installation hole 83 on the inner wall surface of the exterior panel 82, whereby the guide tube portion 84a faces the exterior panel 82 obliquely downward as it goes from the indoor side to the outdoor side. It is accommodated in the installation hole 83 in such a posture. In this state, the first sheath tube guide 84 is fixed to the exterior panel 82 by tightening the screws 90 that are passed through screw holes (not shown) of the flange portion 84 b and screwed into the exterior panel 82. In this installed state, the outer peripheral surface of the guide tube portion 84a and the inner peripheral surface of the installation hole 83 are not in contact with each other, and a gap g is provided between them as shown in FIG.

なお、本実施形態の構成に加えて、ガイド筒部84aのフランジ部84b側の根元部外周に設置穴83と略同径のスペーサ段部を周方向に連続或いは非連続に設けて実施する場合には、この段部によって設置穴83の径方向に対するガイド筒部84aの位置決めができる。そのため、ガイド筒部84aを設置穴83に対する同軸度を簡単に出して外装パネル82の第1鞘管ガイド84を固定できる点で優れるとともに、次に述べる第2鞘管ガイド85との嵌合においても両ガイド筒部84a、85aの先端同士が互いに当るような相互干渉を防止できるので、壁通し具81の設置作業性を容易にできる点でも優れる。   In addition to the configuration of the present embodiment, a case where the spacer step portion having the same diameter as the installation hole 83 is provided continuously or discontinuously in the circumferential direction on the outer periphery of the base portion on the flange portion 84b side of the guide tube portion 84a. In addition, the guide tube portion 84a can be positioned with respect to the radial direction of the installation hole 83 by this step portion. Therefore, the guide tube portion 84a is excellent in that the coaxiality with respect to the installation hole 83 can be easily obtained and the first sheath tube guide 84 of the exterior panel 82 can be fixed, and in the fitting with the second sheath tube guide 85 described below. In addition, since it is possible to prevent mutual interference such that the tips of the guide tube portions 84a and 85a come into contact with each other, it is excellent in that the installation workability of the wall threading tool 81 can be facilitated.

次に、外装パネル82の屋外側から第2鞘管ガイド85を、フランジ部85bがない方のガイド筒部85aの端部を先頭にして設置穴83にその内周面に沿わせながら挿入させる。この挿入はフランジ部85bが外装パネル82の外壁面において設置穴83の穴縁に引っ掛るまで行われ、それにより、ガイド筒部85aは外装パネル82を屋外側から屋内側に行くにしたがって斜め上向きにとなる姿勢で設置穴83内に収容される。   Next, the second casing tube guide 85 is inserted from the outdoor side of the exterior panel 82 into the installation hole 83 along the inner peripheral surface with the end of the guide tube portion 85a without the flange portion 85b at the top. . This insertion is performed until the flange portion 85b is caught on the edge of the installation hole 83 on the outer wall surface of the exterior panel 82, whereby the guide tube portion 85a is inclined upward as the exterior panel 82 is moved from the outdoor side to the indoor side. It is accommodated in the installation hole 83 in such a posture.

このとき、ガイド筒部85aが、前記ガイド筒部84aの外周面と設置穴83の内周面と間の空隙gに挿入されて、ガイド筒部84aの外側に嵌合される。同時に、この筒部85aに設けられた第1引掛り部86が外装パネル82の厚みに適合した位置の第2引掛り部例えば第2引掛り部89を節度感を伴いながら乗り越えて、これに引掛かる(図15参照)。これらの引掛り部86、89の係合により第2鞘管ガイド85は第1鞘管ガイド84に連結されるから、以上の挿入作業を終えて第2鞘管ガイド85から手を離しても、このガイド85が斜め下方に脱落することがない。   At this time, the guide tube portion 85a is inserted into the gap g between the outer peripheral surface of the guide tube portion 84a and the inner peripheral surface of the installation hole 83, and is fitted to the outside of the guide tube portion 84a. At the same time, the first hooking portion 86 provided on the cylindrical portion 85a gets over the second hooking portion, for example, the second hooking portion 89, at a position suitable for the thickness of the exterior panel 82 with a sense of moderation. It catches (see FIG. 15). Since the second sheath tube guide 85 is connected to the first sheath tube guide 84 by the engagement of these hook portions 86 and 89, even if the second sheath tube guide 85 is released after the above insertion operation is finished, The guide 85 does not fall off obliquely downward.

そして、このように両鞘管ガイド84、85が連結された状態で、第2鞘管ガイド85のフランジ部85bの図示しないねじ通し穴に通されて外装パネル82にねじ込まれるねじ91を夫々締付けて、第2鞘管ガイド85を外装パネル82に固定する。この場合、既述のように第2鞘管ガイド85が脱落しないように第1鞘管ガイド84に支持されているので、ねじ91の締め付け作業において第2鞘管ガイド85の脱落を片手で阻止しつつ作業を行なう面倒がないので、容易にねじ止めすることができる。   Then, in a state where the two sheath tube guides 84 and 85 are connected in this manner, the screws 91 that are passed through the screw through holes (not shown) of the flange portion 85b of the second sheath tube guide 85 and screwed into the exterior panel 82 are respectively tightened. Then, the second sheath tube guide 85 is fixed to the exterior panel 82. In this case, as described above, the second sheath tube guide 85 is supported by the first sheath tube guide 84 so that the second sheath tube guide 85 does not fall off. However, since there is no trouble of performing the work, it can be easily screwed.

最後に、図15及び図16に示されるようにフランジ部85bとその周囲の外装パネル82の外壁面とにわたってコーキング材92を設けて止水処理をする。それにより設置穴83と第2鞘管ガイド85との間への屋外からの浸水を防止できる。なお、この止水処理に代えて、フランジ部85bと外装パネル82の外面との間に止水パッキンを接着することもできる。   Finally, as shown in FIGS. 15 and 16, a caulking material 92 is provided over the flange portion 85b and the outer wall surface of the surrounding exterior panel 82 to perform a water stop treatment. Accordingly, it is possible to prevent water from entering between the installation hole 83 and the second sheath tube guide 85 from the outside. Instead of the water stop treatment, a water stop packing can be bonded between the flange portion 85b and the outer surface of the exterior panel 82.

以上の手順により、フランジ部84b、85a間に外装パネル82を挟んだ状態で外装パネル82を斜めに貫通して壁通し具81が設置される。   Through the above procedure, the wall threading tool 81 is installed through the exterior panel 82 obliquely with the exterior panel 82 sandwiched between the flange portions 84b and 85a.

この後には、互いに連結された外装パネル82を斜めに貫通した第1、第2鞘管ガイド84、85を備えた壁通し具81の互いに連続するガイド筒部84a、85aに外装パネル82の例えば内壁面側から鞘管5を通して、この鞘管5を外装パネル82に対して斜めに貫通させた後、この鞘管5内に外装パネル82の外面側から配管4を挿入することにより、鞘管5内を通して所定の場所に配管4を導いて配設する。   Thereafter, the guide tube portions 84a and 85a of the wall threading tool 81 including the first and second sheath tube guides 84 and 85 obliquely passing through the mutually connected exterior panels 82 are connected to the guide tube portions 84a and 85a of the exterior panel 82, for example. After the sheath tube 5 is obliquely penetrated with respect to the exterior panel 82 through the sheath tube 5 from the inner wall surface side, the pipe 4 is inserted into the sheath tube 5 from the outer surface side of the exterior panel 82, whereby the sheath tube The pipe 4 is led and arranged at a predetermined place through the inside 5.

この場合、第1鞘管ガイド84のガイド筒部84aが第2鞘管ガイド85のガイド筒部85aの内側に嵌合されているから、屋内側から鞘管5を壁通し具81を貫通する鞘管5が、ガイド筒部85aの先端に引掛る恐れがなく、したがって、鞘管5の挿通作業性がよい。この設置状態において、屋外側の鞘管ガイド85と鞘管5との間の止水を行なう場合には、これらにわたって図示しないコーキング材を充填することで行なえばよい。   In this case, since the guide tube portion 84a of the first sheath tube guide 84 is fitted inside the guide tube portion 85a of the second sheath tube guide 85, the sheath tube 5 passes through the wall threading tool 81 from the indoor side. The sheath tube 5 is not likely to be caught at the tip of the guide tube portion 85a, and therefore the workability of inserting the sheath tube 5 is good. In this installation state, when water is shut off between the sheath pipe guide 85 and the sheath pipe 5 on the outdoor side, it may be performed by filling a caulking material (not shown) over them.

なお、以上の点以外の接続作業等は前記第1の実施の形態と同じである。又、プレハブ住宅の外装パネル82に対してはその生産段階で予め壁通し具81を装着して置くことができるので、このようにして建築現場に供給する場合には、建築現場では壁通し具81を外装パネル82に設置する作業を要することがなくなり、したがって、建築現場での鞘管5及び配管4の配設作業を速やかに開始することができる。   The connection work other than the above points is the same as in the first embodiment. In addition, since the wall threading tool 81 can be mounted and placed in advance on the exterior panel 82 of the prefabricated house in the production stage, the wall threading tool is used at the construction site when supplying it to the construction site in this way. The operation of installing 81 on the exterior panel 82 is not required, and therefore the operation of arranging the sheath pipe 5 and the pipe 4 at the construction site can be started quickly.

以上説明した壁貫通配管の壁通し具81を用いた配管4及び鞘管5の配設作業によれば、外装パネル82を斜めに貫通して設けられた壁通し具81に鞘管5を通すことで、外装パネル82の内壁面に沿うように鞘管5を屋内へと配設でき、外装パネル82の屋内側の狭い壁裏空間内においても鞘管5を無理に折り曲げて座屈変形を起こさせることがない。このため、鞘管5の内部に通して屋外から屋内へと配設する配管4も無理に折り曲げて座屈変形を起こさせることなく、容易に配設できる。さらに、屋外側より配管4を斜め下方に引っ張ることにより、挿入時と同様に鞘管5をガイドとして少ない抵抗で容易に配管4を引き出せるので、こうした配管4の出し入れ操作によって、将来において配管4が老朽化した場合の配管4の更新作業も簡単に行うことができる。   According to the arrangement work of the pipe 4 and the sheath tube 5 using the wall threading tool 81 of the wall penetration pipe described above, the sheath pipe 5 is passed through the wall threading tool 81 provided obliquely through the exterior panel 82. Thus, the sheath tube 5 can be arranged indoors along the inner wall surface of the exterior panel 82, and the sheath tube 5 is forcibly bent in the narrow wall space on the indoor side of the exterior panel 82 to cause buckling deformation. There is no waking. For this reason, the pipe 4 that passes through the inside of the sheath pipe 5 and is arranged from the outside to the inside can be easily arranged without forcibly bending and causing buckling deformation. Further, by pulling the pipe 4 obliquely downward from the outdoor side, the pipe 4 can be easily pulled out with less resistance using the sheath pipe 5 as a guide as in the insertion. The work of updating the pipe 4 when it is aged can be easily performed.

しかも、前記壁通し具81の採用により、鞘管5を外装パネル82の位置において途切れることなく屋外から屋内へと連続して配設できるため、屋内で配管4から水が漏れ出しても鞘管5の内部を伝わって屋外へと排出され、屋内への浸水のおそれが低いとともに、外装パネル82を貫通した配管4に対する継手部分は外装パネル82の屋外側にあるので、漏水し易い前記継手部分からの漏水があっても屋内へ浸水するおそれがない。   Moreover, since the sheath tube 5 can be continuously arranged from the outdoor to the indoor without being interrupted at the position of the exterior panel 82 by employing the wall threading tool 81, the sheath tube can be used even if water leaks from the piping 4 indoors. 5, which is discharged to the outside through the inside of the interior 5 and has a low risk of flooding indoors, and since the joint portion for the pipe 4 penetrating the exterior panel 82 is on the exterior side of the exterior panel 82, the joint portion easily leaks. There is no risk of flooding indoors even if water leaks from the water.

又、屋外側の第2鞘管ガイド85は屋外側に向けて斜めに下がるように傾斜して外装パネル82をねじ止めされているので、雨水等が斜めの壁通し具81内のガイド筒部84a、85aを通って屋外から屋内へと浸入するおそれが殆どない。   Further, the second outer sheath guide 85 on the outdoor side is inclined so as to be inclined downward toward the outdoor side, and the exterior panel 82 is screwed, so that rainwater or the like is a guide tube portion in the diagonal wall threading tool 81. There is almost no risk of entering the indoors from the outdoors through 84a and 85a.

更に、この壁通し具81は、第1、第2の鞘管ガイド84、85のフランジ部84b、85bで、外装パネル82を厚み方向から挟み込むサンドイッチ構造をとっているので、設置穴83と壁通し具81のガイド筒部84a、85aとの間の埋め戻し作業等の閉栓処理も不要にでき、施工性がよい。その上、前記サンドイッチ構造により、鞘管ガイド84、85に新規に配管4を通すときは勿論のこと、老朽化した配管4を新品の配管と交換するときにおいても、配管4や鞘管5を壁通し具81に通す際等に加わる操作力を、配管4等を押し込んだり、引き出したりする操作方向の上流側において外装パネル82に引掛かっているフランジ部84b又は85bに波及させて外装パネル82で分散して支持できる。よって、壁通し具81が外装パネル82から不用意に外れたり、外装パネル82とこれを挟んだフランジ部84b又は85bとの接合が緩むことがなく、したがって、防水性が損なわれるおそれを低くできる。   Further, since the wall threading tool 81 has a sandwich structure in which the outer panel 82 is sandwiched from the thickness direction by the flange portions 84b and 85b of the first and second sheath tube guides 84 and 85, the installation hole 83 and the wall A plugging process such as a backfilling operation between the guide tube portions 84a and 85a of the threading tool 81 can be made unnecessary, and the workability is good. Moreover, due to the sandwich structure, not only when the pipe 4 is newly passed through the sheath guides 84 and 85, but also when the old pipe 4 is replaced with a new pipe, the pipe 4 and the sheath pipe 5 are The operating force applied when passing through the wall threading tool 81 is propagated to the flange portion 84b or 85b hooked to the exterior panel 82 on the upstream side in the operation direction in which the piping 4 or the like is pushed in or pulled out. Can be dispersed and supported. Therefore, the wall threading tool 81 is not inadvertently detached from the exterior panel 82 or the joint between the exterior panel 82 and the flange portion 84b or 85b sandwiching the exterior panel 82 is not loosened. .

又、前記構成の壁通し具81の採用により、大きな円形の穴を外装パネル82に設ける必要がなく、斜めの設置穴83を設けることに伴う外装パネル82の強度の低下を抑制できる。しかも、この第7実施形態に係る壁通し具81は、その構成部品が二つで済むので、構造が簡単であり、安価に提供できるとともに、その外装パネル82への固定も通常のねじ止め作業により容易に行なうことができる。なお、この第7実施形態において、フランジ部84b、85bを外装パネル82に固定する手段は、ねじ止めに代えて、接着剤や両面接着テープ等の接着手段を用いてもよいものであり、また、第1引掛り部86と第2の引掛り部87〜89との引掛りによる連結強度が大きく、それにより両フランジ部84b、85bが外装パネル82の内外壁面に夫々圧接する場合には、前記固定手段は省略してもよい。   In addition, by adopting the wall threading tool 81 having the above-described configuration, it is not necessary to provide a large circular hole in the exterior panel 82, and it is possible to suppress a decrease in strength of the exterior panel 82 due to the provision of the oblique installation hole 83. Moreover, since the wall threading tool 81 according to the seventh embodiment requires only two components, the structure is simple and can be provided at a low cost, and the fixing to the exterior panel 82 is also a normal screwing operation. This can be done easily. In the seventh embodiment, the means for fixing the flange portions 84b and 85b to the exterior panel 82 may be an adhesive means such as an adhesive or a double-sided adhesive tape instead of screwing. In the case where the connection strength due to the hooking between the first hooking portion 86 and the second hooking portions 87 to 89 is large, and both the flange portions 84b and 85b are pressed against the inner and outer wall surfaces of the exterior panel 82, respectively, The fixing means may be omitted.

次に、図18を参照して本発明の第7の実施の形態に係る壁貫通配管の壁通し具101を説明する。なお、以下説明する壁通し具101及び壁の設置穴103以外は、図18に示されない部分を含めて前記第1の実施の形態と同じであるから、鞘管及び配管等の同一部分についての説明は、第1の実施の形態と同じ符号を付してその説明を省略し、異なる部分についてのみ説明する。
(Embodiment 8)
Next, a wall threading tool 101 of a wall through pipe according to a seventh embodiment of the present invention will be described with reference to FIG. In addition, since it is the same as that of the said 1st Embodiment including the part which is not shown in FIG. 18 except the wall threading tool 101 and the wall installation hole 103 which are demonstrated below, about the same parts, such as a sheath pipe and piping, In the description, the same reference numerals as those in the first embodiment are attached, the description thereof is omitted, and only different portions will be described.

この第8の実施形態に係る壁通し具101が設置される住宅の壁、本実施形態の場合にはプレハブ工法により作られる住宅の外装パネル(外壁)102の所定位置には斜めに貫通する断面円形の設置穴103が開けられている。この穴103は屋内側から屋外側に行くにしたがって次第に下がるように傾斜しており、その壁貫通角度θは45°である。壁通し具101は、金属又は硬質合成樹脂により一体成形された単一の部品で形成されていて、鞘管ガイド104と、フランジ部105とを有している。   Section of the wall of the house where the wall threading tool 101 according to the eighth embodiment is installed, in the case of this embodiment, obliquely penetrates to a predetermined position of the exterior panel (outer wall) 102 of the house made by the prefabricated method A circular installation hole 103 is opened. The hole 103 is inclined so as to gradually fall from the indoor side to the outdoor side, and the wall penetration angle θ is 45 °. The wall threading tool 101 is formed of a single part integrally formed of metal or hard synthetic resin, and includes a sheath tube guide 104 and a flange portion 105.

詳しくは、鞘管ガイド104は外装パネル102の厚みよりも短い円筒からなり、その一端部外周に周方向に連続して円形をなすフランジ部105が一体に設けられている。鞘管ガイド104の外径は設置穴103の穴径に略等しく、そして、フランジ部105がない方の鞘管ガイド104の端部内周面にはテーパ面104aが設けられている。フランジ部105は鞘管ガイド104の軸線に対して交差する方向に沿って外側に張り出して設けられており、その複数箇所には図示しないねじ通し穴が開けられている。   Specifically, the sheath tube guide 104 is formed of a cylinder shorter than the thickness of the exterior panel 102, and a flange portion 105 that is continuously circular in the circumferential direction is integrally provided on the outer periphery of one end portion thereof. The outer diameter of the sheath tube guide 104 is substantially equal to the hole diameter of the installation hole 103, and a tapered surface 104 a is provided on the inner peripheral surface of the end portion of the sheath tube guide 104 without the flange portion 105. The flange portion 105 is provided so as to project outward along a direction intersecting the axis of the sheath guide 104, and screw holes (not shown) are formed at a plurality of locations.

次に、前記構成の壁貫通配管の壁通し具101を用いた配管4及び鞘管5の配設作業を説明する。まず、外装パネル102に壁通し具101を設置する手順を説明する。   Next, the arrangement | positioning operation | work of the piping 4 and the sheath tube 5 using the wall threading tool 101 of the wall penetration piping of the said structure is demonstrated. First, a procedure for installing the wall threading tool 101 on the exterior panel 102 will be described.

テーパ面104aがある方の鞘管ガイド104の端部を先頭にして壁通し具101を、外装パネル102の屋外側から設置穴103に挿入させる。この挿入はフランジ部105が外装パネル102の外壁面に置いて設置穴103の穴縁に引っ掛るまで行われ、それにより、鞘管ガイド104が外装パネル102を屋外側から屋内側に行くにしたがって斜め上向きにとなる姿勢で設置穴103内に収容される。この状態で、フランジ部105の図示しないねじ通し穴に通されて外装パネル102にねじ込まれるねじ106を夫々締付けて、壁通し具101を外装パネル102に固定する。最後に、フランジ部105とその周囲の外装パネル102の外壁面とにわたってコーキング材107を設けて止水処理をする。それにより設置穴103と壁通し具101との間への屋外からの浸水を防止できる。なお、この止水処理に代えて、フランジ部105と外装パネル102の外面との間に止水パッキンを接着することもできる。   The wall threading tool 101 is inserted into the installation hole 103 from the exterior side of the exterior panel 102 with the end of the sheath tube guide 104 having the tapered surface 104a at the top. This insertion is performed until the flange portion 105 is placed on the outer wall surface of the exterior panel 102 and is caught by the hole edge of the installation hole 103, so that the sheath tube guide 104 moves the exterior panel 102 from the outdoor side to the indoor side. It is accommodated in the installation hole 103 in a posture that is inclined upward. In this state, the screws 106 passed through the screw through holes (not shown) of the flange portion 105 and screwed into the exterior panel 102 are tightened to fix the wall threading tool 101 to the exterior panel 102. Finally, a caulking material 107 is provided over the flange portion 105 and the outer wall surface of the surrounding exterior panel 102 to perform a water stop treatment. Accordingly, it is possible to prevent water from entering between the installation hole 103 and the wall threading tool 101 from the outside. Instead of this water stop treatment, a water stop packing can be bonded between the flange portion 105 and the outer surface of the exterior panel 102.

以上の手順により外装パネル102を斜めに貫通して壁通し具101が設置される。   The wall threading tool 101 is installed through the exterior panel 102 obliquely by the above procedure.

この後には、鞘管ガイド104に外装パネル102の例えば内壁面側から鞘管5を通して、この鞘管5を外装パネル102に対して斜めに貫通させた後、この鞘管5内に外装パネル102の外面側から配管4を挿入することにより、鞘管5内を通して所定の場所に配管4を導いて配設する。   Thereafter, the sheath tube 5 is passed through the sheath tube guide 104 from, for example, the inner wall surface side of the exterior panel 102 through the sheath tube 5 obliquely with respect to the exterior panel 102, and then the exterior panel 102 is inserted into the sheath tube 5. By inserting the pipe 4 from the outer surface side of the pipe, the pipe 4 is led to a predetermined place through the inside of the sheath pipe 5.

この場合、鞘管ガイド104の先端部にはテーパ面104aが設けられているから、屋内側から鞘管5を壁通し具101を貫通する鞘管5が、鞘管ガイド104の先端に引掛る恐れが少なく、したがって、鞘管5の挿通作業性がよい。この設置状態において、屋外側で壁通し具101と鞘管5との間の止水を行なう場合には、これらにわたって図示しないコーキング材を充填することで行なえばよい。   In this case, since the tapered surface 104 a is provided at the distal end portion of the sheath tube guide 104, the sheath tube 5 that penetrates the sheath tube 5 through the wall threading tool 101 from the indoor side is hooked on the distal end of the sheath tube guide 104. There is little fear, therefore, the workability of inserting the sheath tube 5 is good. In this installed state, when water is stopped between the wall threading tool 101 and the sheath tube 5 on the outdoor side, it may be performed by filling a caulking material (not shown) over them.

なお、以上の点以外の接続作業等は前記第1の実施の形態と同じである。又、プレハブ住宅の外装パネル102に対してはその生産段階で予め壁通し具101を装着して置くことができるので、このようにして建築現場に供給する場合には、建築現場では壁通し具101を外装パネル102に設置する作業を要することがなくなり、したがって、建築現場での鞘管5及び配管4の配設作業を速やかに開始させることができる。   The connection work other than the above points is the same as in the first embodiment. Further, since the wall threading tool 101 can be mounted and placed in advance on the exterior panel 102 of the prefabricated house in the production stage, the wall threading tool is used at the construction site when supplying it to the construction site in this way. The operation of installing 101 on the exterior panel 102 is not required, and therefore, the disposing operation of the sheath pipe 5 and the pipe 4 at the construction site can be started promptly.

以上説明した壁貫通配管の壁通し具101を用いた配管4及び鞘管5の配設作業によれば、外装パネル102を斜めに貫通して設けられた壁通し具101に鞘管5を通すことで、外装パネル102の内壁面に沿うように鞘管5を屋内へと配設でき、外装パネル102の屋内側の狭い壁裏空間内においても鞘管5を無理に折り曲げて座屈変形を起こさせることがない。このため、鞘管5の内部に通して屋外から屋内へと配設する配管4も無理に折り曲げて座屈変形を起こさせることなく、容易に配設できる。さらに、屋外側より配管4を斜め下方に引っ張ることにより、挿入時と同様に鞘管5をガイドとして少ない抵抗で容易に配管4を引き出せるので、こうした配管4の出し入れ操作によって、将来において配管4が老朽化した場合の配管4の更新作業も簡単に行うことができる。   According to the arrangement work of the pipe 4 and the sheath tube 5 using the wall threading tool 101 of the wall penetration pipe described above, the sheath pipe 5 is passed through the wall threading tool 101 provided obliquely through the exterior panel 102. Thus, the sheath tube 5 can be disposed indoors along the inner wall surface of the exterior panel 102, and the sheath tube 5 is forcibly bent in the narrow wall space on the indoor side of the exterior panel 102 to cause buckling deformation. There is no waking. For this reason, the pipe 4 that passes through the inside of the sheath pipe 5 and is arranged from the outside to the inside can be easily arranged without forcibly bending and causing buckling deformation. Further, by pulling the pipe 4 obliquely downward from the outdoor side, the pipe 4 can be easily pulled out with less resistance using the sheath pipe 5 as a guide as in the insertion. The work of updating the pipe 4 when it is aged can be easily performed.

しかも、前記壁通し具101の採用により、鞘管5を外装パネル102の位置において途切れることなく屋外から屋内へと連続して配設できるため、屋内で配管4から水が漏れ出しても鞘管5の内部を伝わって屋外へと排出され、屋内への浸水のおそれが低いとともに、外装パネル102を貫通した配管4に対する継手部分は外装パネル102の屋外側にあるので、漏水し易い前記継手部分からの漏水があっても屋内へ浸水するおそれがない。   Moreover, since the sheath tube 5 can be continuously arranged from the outdoor to the indoor without being interrupted at the position of the exterior panel 102 by using the wall threading tool 101, the sheath tube can be used even if water leaks from the piping 4 indoors. The joint portion that is discharged to the outside through the interior of the interior 5 and is less likely to be flooded indoors, and the joint portion for the pipe 4 penetrating the exterior panel 102 is on the outdoor side of the exterior panel 102, so that the joint portion easily leaks. There is no risk of flooding indoors even if water leaks from the water.

又、この壁通し具101は屋外側に向けて斜めに下がるように傾斜して外装パネル102にねじ止めされているので、雨水等が斜めの壁通し具101の鞘管ガイド104を通って屋外から屋内へと浸入するおそれが殆どない。更に、この壁通し具101は、フランジ部105で設置穴103の屋外側の開口を覆い隠しているので、設置穴103と鞘管ガイド104との間の埋め戻し作業等の閉栓処理も不要にでき、施工性がよい。   Further, since the wall threading tool 101 is inclined so as to be inclined obliquely toward the outdoor side and is screwed to the exterior panel 102, rainwater or the like passes through the sheath tube guide 104 of the oblique wall threading tool 101 and is outdoors. There is almost no risk of entering the house indoors. Further, since the wall threading tool 101 covers and conceals the opening on the outdoor side of the installation hole 103 with the flange portion 105, plugging processing such as backfilling work between the installation hole 103 and the sheath guide 104 is unnecessary. Yes, workability is good.

又、前記構成の壁通し具101の採用により、大きな円形の穴を外装パネル102に設ける必要がなく、斜めの設置穴103を設けることに伴う外装パネル102の強度の低下を抑制できる。しかも、この第8実施形態に係る壁通し具101は、その構成部品が一つで済むので、構造が極めて簡単であり、より安価に提供できるとともに、その外装パネル102への固定も通常のねじ止め作業により容易に行なうことができる。なお、この第8実施形態において、フランジ部105を外装パネル102に固定する手段は、ねじ止めに代えて、接着剤や両面接着テープ等の接着手段を用いることができる。   Further, by adopting the wall threading tool 101 having the above-described configuration, it is not necessary to provide a large circular hole in the exterior panel 102, and a decrease in strength of the exterior panel 102 due to the provision of the oblique installation hole 103 can be suppressed. Moreover, since the wall threading tool 101 according to the eighth embodiment requires only one component, the structure is extremely simple and can be provided at a lower cost, and the fixing to the exterior panel 102 is also possible with an ordinary screw. It can be easily performed by a stop operation. In the eighth embodiment, as means for fixing the flange portion 105 to the exterior panel 102, an adhesive means such as an adhesive or a double-sided adhesive tape can be used instead of screwing.

(実施形態9)
次に、図19から図21を参照して本発明の第9の実施の形態に係る壁貫通配管の壁通し具1を説明する。なお、前述した第1から第4の実施の形態に係る壁貫通配管の壁通し具1と同一構成部分には、同一符号を付して説明を省略する。
(Embodiment 9)
Next, a wall threading tool 1 for a wall through pipe according to a ninth embodiment of the present invention will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected to the same component as the wall threading tool 1 of wall penetration piping which concerns on the 1st to 4th embodiment mentioned above, and description is abbreviate | omitted.

本実施の形態の壁通し具1が取付けられる設置穴3は、外壁2に対し直交する方向に沿って、この外壁2を貫通している。設置穴3は丸形に形成されている。また、本実施形態の壁通し具1は、屋外Oから屋内Iに向うにしたがって上方から下方に向って給湯器などから供給される湯を導くために用いられる。   The installation hole 3 to which the wall threading tool 1 of the present embodiment is attached passes through the outer wall 2 along a direction orthogonal to the outer wall 2. The installation hole 3 is formed in a round shape. Moreover, the wall threading tool 1 of this embodiment is used in order to guide the hot water supplied from the water heater or the like from the upper side to the lower side as it goes from the outdoor O to the indoor I.

図19から図21に示すように、本実施形態の壁貫通配管の壁通し具1は、第1壁通し部材6だけで構成されている。本実施形態の第1壁通し部材6は、その第1筒部8が円筒状に形成されている。第1筒部8はその軸線Pが、壁通し具1が設置穴3に取付けられた際に、外壁2に対し直交する方向に沿う。   As shown in FIGS. 19 to 21, the wall threading tool 1 of the wall through pipe according to the present embodiment is composed of only the first wall threading member 6. As for the 1st wall threading member 6 of this embodiment, the 1st cylinder part 8 is formed in the cylindrical shape. The first cylindrical portion 8 has an axis P along a direction orthogonal to the outer wall 2 when the wall threading tool 1 is attached to the installation hole 3.

壁通し具1が設置穴3に取付けられた際に、第1筒部8の鉛直方向に沿った幅Dは、鞘管5の外径dの約2から3倍以上の寸法に形成されている。第1筒部8の鉛直方向に沿った幅Dは、鞘管5の外径dより十分大きく形成されている。また、第1壁通し部材6は、壁通し具1が設置穴3に取付けられた際に、第1筒部8の屋外O側に露出する一端部8aに閉塞部12を設けている。   When the wall threading tool 1 is attached to the installation hole 3, the width D along the vertical direction of the first tube portion 8 is formed to be about 2 to 3 times the outer diameter d of the sheath tube 5. Yes. A width D along the vertical direction of the first cylindrical portion 8 is formed sufficiently larger than the outer diameter d of the sheath tube 5. Further, the first wall passing member 6 is provided with a closing portion 12 at one end portion 8a exposed to the outdoor O side of the first cylindrical portion 8 when the wall threading tool 1 is attached to the installation hole 3.

鞘管ガイド13は、前記閉塞部12から屋外O側でかつ斜め上方に向って突出して形成されている。鞘管ガイド13は、前記軸線Pより上方に位置する閉塞部12の端部から突出している。第1筒部8の内側において鞘管ガイド13と閉塞部12との接合部には、滑らかに湾曲した湾曲面110が形成されている。鞘管ガイド13は閉塞部12の内面12aより第1筒部8の内側には突出していない。   The sheath tube guide 13 is formed so as to protrude from the closed portion 12 on the outdoor O side and obliquely upward. The sheath tube guide 13 protrudes from the end portion of the closing portion 12 positioned above the axis P. A smoothly curved surface 110 is formed at the joint between the sheath guide 13 and the closing portion 12 inside the first tube portion 8. The sheath tube guide 13 does not protrude from the inner surface 12 a of the closing portion 12 to the inside of the first tube portion 8.

第1筒部8の外周面には、全周に亘って止水パッキン14が設けられている。この止水パッキン14は、第1筒部8と設置穴3の内面との間の隙間Gを埋めて、この隙間Gを通る雨水などの屋内Iへの浸入を防止する。止水パッキン14の代わりに周知のコーキング材を用いて前記隙間Gを埋めるようにしても良い。   A water-stop packing 14 is provided on the outer peripheral surface of the first cylinder portion 8 over the entire circumference. This water-stopping packing 14 fills a gap G between the first tube portion 8 and the inner surface of the installation hole 3, and prevents intrusion of rainwater or the like passing through the gap G into the indoor I. The gap G may be filled using a known caulking material instead of the water stop packing 14.

鞘管ガイド13の屋内I側に位置する他端部8bには、フランジ取付け部111が形成されている。このフランジ取付け部111には、設置穴3の穴縁に引掛るフランジ部材112が取付けられるようになっている。   A flange mounting portion 111 is formed on the other end portion 8 b located on the indoor I side of the sheath guide 13. A flange member 112 hooked to the hole edge of the installation hole 3 is attached to the flange attachment portion 111.

フランジ取付け部111は、第1筒部8の外周面に形成されかつこの外周面から凹に形成された凹溝113を複数備えている。図示例において、フランジ取付け部111は、凹溝113を二つ備えている。それぞれの凹溝113は、前記他端部8bのうち少なくとも前記軸線Pより鞘管ガイド13が設けられた側の外周面に、第1筒部8の周方向に沿って形成されている。それぞれの凹溝113は、壁通し具1が設置穴3に取付けられた際に、外壁2に沿うように形成されている。   The flange mounting portion 111 includes a plurality of concave grooves 113 formed on the outer peripheral surface of the first cylindrical portion 8 and formed concavely from the outer peripheral surface. In the illustrated example, the flange mounting portion 111 includes two concave grooves 113. Each concave groove 113 is formed along the circumferential direction of the first cylindrical portion 8 on the outer peripheral surface of the other end portion 8b at least on the side where the sheath tube guide 13 is provided from the axis P. Each concave groove 113 is formed along the outer wall 2 when the wall threading tool 1 is attached to the installation hole 3.

それぞれの凹溝113は、前記閉塞部12の表面12bからの距離が壁通し具1が取付けられる外壁2の厚みに応じた位置に形成されるのが望ましい。凹溝113は、前記閉塞部12の表面12bからの距離が互いに異なる位置に形成されている。また、それぞれの凹溝113は、前記他端部8bのうち軸線Pより鞘管ガイド13が配置されていない側の外周面には形成されていない。   Each of the concave grooves 113 is preferably formed at a position where the distance from the surface 12b of the blocking portion 12 corresponds to the thickness of the outer wall 2 to which the wall threading tool 1 is attached. The concave groove 113 is formed at a position where the distances from the surface 12b of the closing portion 12 are different from each other. Further, each of the concave grooves 113 is not formed on the outer peripheral surface of the other end portion 8b on the side where the sheath pipe guide 13 is not disposed from the axis P.

フランジ部材112は、馬蹄形に形成されているとともに、凹溝113に係合するようになっている。フランジ部材112は、壁通し具1が設置穴3内に嵌め込まれた際に、上方から凹溝113に係合する。フランジ部材112は、凹溝113に係合すると、その端面が設置穴3の穴縁に引っ掛る。   The flange member 112 is formed in a horseshoe shape and engages with the concave groove 113. The flange member 112 engages with the groove 113 from above when the wall threading tool 1 is fitted into the installation hole 3. When the flange member 112 is engaged with the concave groove 113, the end surface thereof is caught by the hole edge of the installation hole 3.

フランジ部材112には、複数の貫通穴114が形成されている。これらの貫通穴114には、それぞれ、フランジ部材112を外壁2に固定するねじ115が通るようになっている。   A plurality of through holes 114 are formed in the flange member 112. A screw 115 for fixing the flange member 112 to the outer wall 2 passes through each of these through holes 114.

第1筒部8は、その他端部8bの縁部8cが上方から下方に向うにしたがって即ち鞘管ガイド13から離れるのにしたがって、徐々に外壁2の外面側に近づく方向に傾斜するように形成されている。この他端部8bにおいて、前記軸線Pより鞘管ガイド13が設けられた側の縁部8cは、外壁2から屋内I側に突出しているとともに、軸線Pより鞘管ガイド13が配置されていない側の縁部8cは、設置穴3の穴縁より設置穴3内に位置するように形成されている。   The first tube portion 8 is formed so as to be inclined gradually toward the outer surface side of the outer wall 2 as the edge portion 8c of the other end portion 8b is directed downward from above, that is, as the edge portion 8c is separated from the sheath guide 13. Has been. In the other end portion 8b, the edge portion 8c on the side where the sheath tube guide 13 is provided from the axis P projects from the outer wall 2 toward the indoor I side, and the sheath tube guide 13 is not disposed from the axis P. The side edge 8 c is formed so as to be located in the installation hole 3 from the hole edge of the installation hole 3.

前記壁通し具1の具体的な寸法例を示す。前記設置穴3は外壁2の機械的な強度を極力低下させないため、その直径を極力小さく形成するのが望ましい。呼び径が直径13mmの配管4を呼び径が直径28mmの鞘管5に通して、厚さ75mmから100mmの外壁2を貫通させる場合、外壁2を通る配管4及び鞘管5の前記軸線Pに対する挿入角度θ´が23°となるように鞘管ガイド13を閉塞部12に対して設ける。又、このとき、設置穴3の口径は、直径100mmに形成されるのが望ましい。   The example of a specific dimension of the said wall threading tool 1 is shown. Since the installation hole 3 does not reduce the mechanical strength of the outer wall 2 as much as possible, it is desirable to make the diameter as small as possible. When the pipe 4 having a nominal diameter of 13 mm is passed through the sheath pipe 5 having a nominal diameter of 28 mm and penetrates the outer wall 2 having a thickness of 75 mm to 100 mm, the pipe 4 passing through the outer wall 2 and the axis P of the sheath pipe 5 with respect to the axis P The sheath tube guide 13 is provided with respect to the closing portion 12 so that the insertion angle θ ′ is 23 °. At this time, it is desirable that the diameter of the installation hole 3 is formed to a diameter of 100 mm.

次に、この第9の実施の形態の壁通し具1の外壁2の設置穴3への取付け作業を説明する。   Next, an operation of attaching the outer wall 2 of the wall threading tool 1 according to the ninth embodiment to the installation hole 3 will be described.

まず、第1壁通し部材6を、閉塞部12が屋外Oに露出するように、屋外O側から設置穴3内に嵌め込む。外壁2の厚みに応じた凹溝113にフランジ部材112を上方から係合させる。ねじ115を貫通穴114内に通して外壁2にねじ込んで、フランジ部材112とともに第1壁通し部材6を外壁2に固定する。このとき、第1筒部8と設置穴3との間の隙間Gは、止水パッキン14によって全周に亘って隙間なく埋められる。以上で外壁2の設置穴3への第9の実施の形態の壁貫通配管の壁通し具1の取付けが終了する。   First, the first wall passing member 6 is fitted into the installation hole 3 from the outdoor O side so that the blocking portion 12 is exposed to the outdoor O. The flange member 112 is engaged with the concave groove 113 corresponding to the thickness of the outer wall 2 from above. The screw 115 is passed through the through hole 114 and screwed into the outer wall 2, and the first wall passing member 6 is fixed to the outer wall 2 together with the flange member 112. At this time, the gap G between the first cylindrical portion 8 and the installation hole 3 is filled by the water blocking packing 14 without any gap. Thus, the attachment of the wall threading tool 1 of the wall through pipe of the ninth embodiment to the installation hole 3 of the outer wall 2 is completed.

壁通し具1を外壁2に固定した後、屋内I側から鞘管5及び配管4を順次、鞘管ガイド13内に挿入する。鞘管ガイド13の先端部13aから突出した配管4の端部に、継手32を介して、2階などの上方に設置された給湯器に連結した配管116を連結する。この連結を行なう際に、図示例では以下に示す継手部117を用いる。   After fixing the wall threading tool 1 to the outer wall 2, the sheath tube 5 and the pipe 4 are sequentially inserted into the sheath tube guide 13 from the indoor I side. A pipe 116 connected to a water heater installed on the second floor or the like is connected to the end of the pipe 4 protruding from the distal end portion 13 a of the sheath pipe guide 13 through a joint 32. When this connection is performed, the joint portion 117 shown below is used in the illustrated example.

継手部117は、前記継手32と、鞘管ガイド13の先端部13aの外周に形成されたねじ溝118と、このねじ溝118に螺合する継手固定部材119などを備えている。前記継手32は、金属からなりかつ鞘管ガイド13の開口縁13bと当接する鍔部120を一体に備えている。鍔部120は、継手32の全周に亘って設けられている。   The joint portion 117 includes the joint 32, a thread groove 118 formed on the outer periphery of the distal end portion 13a of the sheath tube guide 13, a joint fixing member 119 that is screwed into the thread groove 118, and the like. The joint 32 is integrally provided with a flange 120 made of metal and abutting against the opening edge 13 b of the sheath tube guide 13. The flange 120 is provided over the entire circumference of the joint 32.

継手固定部材119は、合成樹脂などからなりかつその内周に継手32が通ることが可能な円環状に形成されている。継手固定部材119は、円筒状に形成されかつ鞘管ガイド13のねじ溝118に螺合するねじ部121と、このねじ部121の一端から内周側に向って延びた円環状の円環部122と、を一体に備えている。この円環部122は、ねじ部121がねじ溝118に螺合すると継手32の鍔部120を鞘管ガイド13の開口縁13bに向かって押圧する。   The joint fixing member 119 is made of a synthetic resin or the like and is formed in an annular shape that allows the joint 32 to pass through the inner periphery thereof. The joint fixing member 119 is formed in a cylindrical shape and is screwed into the screw groove 118 of the sheath tube guide 13, and an annular ring portion extending from one end of the screw portion 121 toward the inner peripheral side. 122 are integrally provided. The annular portion 122 presses the flange portion 120 of the joint 32 toward the opening edge 13 b of the sheath tube guide 13 when the screw portion 121 is screwed into the screw groove 118.

このように、継手部117は、継手固定部材119が鞘管ガイド13のねじ溝118に螺合して、継手32の鍔部120を鞘管ガイド13の開口縁13bに向かって押圧することによって、鞘管ガイド13の開口部を雨水が入らないように閉じている。   As described above, the joint portion 117 is formed by the joint fixing member 119 being screwed into the thread groove 118 of the sheath tube guide 13 and pressing the flange portion 120 of the joint 32 toward the opening edge 13b of the sheath tube guide 13. The opening of the sheath guide 13 is closed so that rainwater does not enter.

本実施形態によれば、設置穴3内に嵌め込まれた際に第1筒部8の鉛直方向に沿った幅Dが、鞘管5の外径dより十分大きく形成されているので、鞘管5が無理に折り曲げられて座屈変形を起さない十分に広い空間Sを第1筒部8内に確保できる。さらに、第1筒部8の屋内I側に位置する他端部8bのうち軸線Pより鞘管ガイド13が配置されていない側の縁部8cが設置穴3の穴縁より設置穴3内に位置している。   According to the present embodiment, the width D along the vertical direction of the first tube portion 8 when fitted in the installation hole 3 is formed sufficiently larger than the outer diameter d of the sheath tube 5. A sufficiently large space S in which the 5 is forcibly bent and does not cause buckling deformation can be secured in the first tube portion 8. Further, the edge portion 8c on the side where the sheath guide 13 is not disposed from the axis P in the other end portion 8b located on the indoor I side of the first tube portion 8 is located in the installation hole 3 from the hole edge of the installation hole 3. positioned.

このため、外壁2の裏側空間が狭い場合でも、鞘管5が無理に曲げることなく外壁2を貫通させてこの外壁2に沿って配設されることとなる。また、鞘管5が無理に曲げられることがないため、この鞘管5内に容易に配管4を通すことができる。   For this reason, even if the back side space of the outer wall 2 is narrow, the sheath tube 5 is disposed along the outer wall 2 through the outer wall 2 without being bent excessively. Further, since the sheath tube 5 is not forcibly bent, the pipe 4 can be easily passed through the sheath tube 5.

また、この壁貫通配管の壁通し具1が取り付けられる設置穴3が、外壁2に対して直交する方向に沿って貫通しているので、雨水などが第1筒部8の外表面などを伝わって屋内に侵入することを防止できる。本実施形態において、前記設置穴3は、屋外Oから屋内Iに向かうにしたがって、徐々に上方に向かうように外壁2を貫通するように形成されても良い。この場合、雨水の浸入をより一層防止できる。なお、このとき、第1筒部8は、その軸線Pが屋外Oから屋内Iに向かうにしたがって徐々に下方に向かうように傾いて、形成されるのが望ましい。   Moreover, since the installation hole 3 to which the wall threading tool 1 of this wall penetration pipe is attached penetrates along the direction orthogonal to the outer wall 2, rainwater or the like is transmitted through the outer surface of the first cylindrical portion 8 or the like. Intruding indoors. In the present embodiment, the installation hole 3 may be formed so as to penetrate the outer wall 2 so as to gradually go upward as it goes from the outdoor O to the indoor I. In this case, the intrusion of rainwater can be further prevented. At this time, it is desirable that the first cylindrical portion 8 is formed so as to be inclined so that its axis P gradually goes downward as it goes from the outdoor O to the indoor I.

さらに、配管4と、給湯器などに連結した配管116とを互いに連結する継手32が、屋外Oに位置することとなる。また、鞘管5は、鞘管ガイド13の中ほどまで挿入されている。このため、たとえ、この継手32に水漏れが生じても屋内Iへの浸水を防止できる。   Further, the joint 32 that connects the pipe 4 and the pipe 116 connected to the hot water heater or the like is located in the outdoor O. The sheath tube 5 is inserted to the middle of the sheath tube guide 13. For this reason, even if a water leak occurs in the joint 32, it is possible to prevent water from entering the indoor I.

また、フランジ部材112が外壁2にねじ115などによって固定されている。このため、鞘管ガイド13に新規に鞘管5及び配管4を通すときは勿論のこと、老朽化した配管4などを新品と交換するときにおいても、配管4や鞘管5を鞘管ガイド13内に通す際等に加わる操作力を、フランジ部材112に波及させて外壁2で分散して支持できる。   Further, the flange member 112 is fixed to the outer wall 2 with screws 115 or the like. Therefore, not only when the sheath pipe 5 and the pipe 4 are newly passed through the sheath pipe guide 13, but also when the aged pipe 4 is replaced with a new one, the pipe 4 and the sheath pipe 5 are connected to the sheath pipe guide 13. The operating force applied when passing through the inside can be distributed to the flange member 112 and supported by the outer wall 2.

このため、壁通し具1が外壁2などから不用意に外れることを防止できる。したがって、配管4の出し入れに拘わらず外壁2への鞘管5の設置状況を確実に保持することができる。   For this reason, it can prevent that the wall threading tool 1 removes from the outer wall 2 etc. carelessly. Therefore, the installation state of the sheath pipe 5 to the outer wall 2 can be reliably maintained regardless of the insertion / extraction of the pipe 4.

さらに、フランジ取付け部111が、閉塞部12の表面12bからの距離が互いに異なる凹溝113を複数備えている。このため、外壁2の厚みに応じて、フランジ部材112を係合させる凹溝113を任意に選択することによって、互いに異なる厚みの外壁2に形成された設置穴3へも、容易に取付けることができる。   Further, the flange mounting portion 111 includes a plurality of concave grooves 113 having different distances from the surface 12 b of the closing portion 12. For this reason, according to the thickness of the outer wall 2, the concave groove 113 with which the flange member 112 is engaged is arbitrarily selected, so that it can be easily attached to the installation holes 3 formed in the outer walls 2 having different thicknesses. it can.

なお、この例では、鞘管ガイド13の内面中ほどに突設したストッパ13dまで鞘管5を挿入するようになっているが、鞘管5は鞘管ガイド13の外まで引出されても良い。この場合、配管4も鞘管ガイド13の外に引出される。このようにすれば、配管4と配管116との接続部から水漏れが生じたときの屋内Iへの浸水をより高度に防止できる。   In this example, the sheath tube 5 is inserted up to the stopper 13d that protrudes in the middle of the inner surface of the sheath tube guide 13, but the sheath tube 5 may be drawn out of the sheath tube guide 13. . In this case, the pipe 4 is also drawn out of the sheath pipe guide 13. In this way, it is possible to prevent water from entering the indoor I to a higher degree when water leaks from the connecting portion between the pipe 4 and the pipe 116.

(実施形態10)
次に、図22を参照して本発明の第10の実施の形態に係る壁貫通配管の壁通し具1を説明する。なお、前述した第9の実施の形態に係る壁貫通配管の壁通し具1と同一構成部分には、同一符号を付して説明を省略する。
(Embodiment 10)
Next, with reference to FIG. 22, a wall threading tool 1 for a wall through pipe according to a tenth embodiment of the present invention will be described. In addition, the same code | symbol is attached | subjected to the component same as the wall threading tool 1 of wall penetration piping which concerns on 9th Embodiment mentioned above, and description is abbreviate | omitted.

本実施形態の壁通し具1の第1筒部8の一端部8aに、第2のフランジ部材130が着脱自在となっている。本実施形態の壁通し具1の第1筒部8の一端部8aの外周には、全周に亘ってねじ溝131が形成されている。第2のフランジ部材130は、円環状に形成されており、その内周面に前記ねじ溝131に螺合するねじ溝132が全周に亘って形成されている。   A second flange member 130 is detachably attached to one end portion 8a of the first tube portion 8 of the wall threading tool 1 of the present embodiment. A thread groove 131 is formed on the outer periphery of the one end portion 8a of the first tube portion 8 of the wall threading tool 1 of the present embodiment. The second flange member 130 is formed in an annular shape, and a thread groove 132 that is screwed into the thread groove 131 is formed on the entire circumference of the second flange member 130.

本実施形態の壁通し具1を設置穴3に取付ける際には、予め、第2のフランジ部材130を第1筒部8に取付けておく。この第2のフランジ部材130が取付けられた第1筒部8を設置穴3内に嵌め込む。そして、前述した第9の実施の形態の壁通し具1と同様の方法で、外壁2に固定するとともに、配管4と、給湯器などと連結した配管116と、を互いに連結する。   When attaching the wall threading tool 1 of the present embodiment to the installation hole 3, the second flange member 130 is attached to the first tube portion 8 in advance. The first cylinder portion 8 to which the second flange member 130 is attached is fitted into the installation hole 3. And it fixes to the outer wall 2 by the method similar to the wall threading tool 1 of 9th Embodiment mentioned above, and connects the piping 4 and the piping 116 connected with the water heater etc. mutually.

本実施形態によれば、前述した第9の実施の形態の壁通し具1の効果にくわえ、外壁2をフランジ部材112と第2のフランジ部材130とによって挟み込んだ状態で取付けられている。このため、配管4や鞘管5を鞘管ガイド13内に通す際等に加わる操作力を、フランジ部材112及び第2のフランジ部材130に波及させて外壁2でより分散して支持できる。   According to the present embodiment, in addition to the effect of the wall threading tool 1 of the ninth embodiment described above, the outer wall 2 is attached with being sandwiched between the flange member 112 and the second flange member 130. For this reason, the operating force applied when the pipe 4 or the sheath tube 5 is passed through the sheath tube guide 13 spills over the flange member 112 and the second flange member 130 and can be supported more dispersedly by the outer wall 2.

このため、壁通し具1が外壁2などから不用意に外れることをより確実に防止できる。したがって、配管4の出し入れに拘わらず外壁2への鞘管5の設置状況をより確実に保持できる。   For this reason, it can prevent more reliably that the wall threading tool 1 removes from the outer wall 2 etc. carelessly. Therefore, the installation state of the sheath pipe 5 to the outer wall 2 can be more reliably maintained regardless of whether the pipe 4 is inserted or removed.

さらに、第2のフランジ部材130の第1筒部8へのねじ込み量を調整することによって、互いに異なる厚みの外壁2に形成された設置穴3へも、より容易に取付けることができる。したがって、互いに異なる厚みの外壁2への設置性がより向上する。   Furthermore, by adjusting the screwing amount of the second flange member 130 into the first tube portion 8, it can be more easily attached to the installation holes 3 formed in the outer walls 2 having different thicknesses. Therefore, the installation property to the outer walls 2 having different thicknesses is further improved.

なお、本発明は前記第1〜第10の実施の形態には制約されない。例えば、第1〜第10の実施形態において壁貫通配管の壁通し具を住宅の外壁へ取付けるにあたって、ねじによって前記外壁に直接穴を開けられるのを嫌う場合には、防水効果の高い接着剤等を用いて前記外壁に設けられた設置穴に直接取付けても構わない。   The present invention is not limited to the first to tenth embodiments. For example, when attaching the wall through tool of the wall through pipe to the outer wall of the house in the first to tenth embodiments, if you do not want to make a hole in the outer wall directly with a screw, an adhesive with a high waterproof effect, etc. You may attach directly to the installation hole provided in the said outer wall using.

又、配管及び鞘管の配設も、前述のように住宅の外壁を貫通させて屋外から屋内へと引き込むばかりではなく、その逆に屋内から屋外へと引き出しても差し支えない。   In addition, as described above, the pipes and the sheath pipes are not only drawn through the outer wall of the house and drawn from the outside to the inside, but conversely, they can be drawn from the inside to the outside.

又、本発明の壁貫通配管の壁通し具を用いて住宅の外壁を貫通させて屋外と屋内とにわたって配設するものは、給湯器等から延ばされる送液管に限らず、例えば、電話線などの通信系ケーブル、電線などの電力系ケーブル等であってもよい。この場合、鞘管を作る材料もこの内部に通して配設する管や線に合わせて、防電磁波能力に優れたもの等、様々な材料を使い分けることが望ましい。   Moreover, the thing which penetrates the outer wall of a house using the wall threading tool of the wall penetration piping of this invention and is arrange | positioned over the outdoors and indoors is not restricted to the liquid feeding pipe extended from a water heater etc., for example, a telephone line It may be a communication system cable such as a power system cable such as an electric wire. In this case, it is desirable to use various materials such as those having excellent anti-electromagnetic wave capability in accordance with the pipes and wires arranged through the interior of the sheath pipe.

又、以上説明したいずれかの実施形態に記載の壁貫通配管の壁貫通構造は、住宅の壁を貫通する設置孔内に少なくとも一部が位置される筒状の鞘管ガイドを、前記壁に対して斜めとなる姿勢に配置し、前記鞘管ガイドにその傾き方向に鞘管を通してこの鞘管を前記壁に対して斜めに貫通させるとともに、前記鞘管内に配管を通したことを特徴としている。   Further, the wall penetration structure of the wall penetration pipe described in any of the embodiments described above includes a cylindrical sheath tube guide at least partially located in an installation hole that penetrates the wall of the house. It is arranged in an inclined posture with respect to the sheath tube guide, and the sheath tube is passed through the sheath tube obliquely with respect to the wall through the sheath tube in the inclination direction, and a pipe is passed through the sheath tube. .

この壁貫通構造を構成するには、まず、筒状の鞘管ガイドを住宅の壁に対して斜めとなる姿勢に配置する。この配置において鞘管ガイドの少なくとも一部は前記壁を貫通する設置穴内に位置される。次に、前記壁に対して斜めに配置された鞘管ガイドに前記壁の一面側から鞘管を貫通させる。それにより、鞘管は鞘管ガイドの傾斜に沿って設置穴を通り抜けて前記壁を斜めに貫通して設けられる。最後に、鞘管の内側に配管を挿入することにより、壁貫通配管としての鞘管及び配管を夫々前記壁に対して斜めに貫通させた壁貫通構造が形成され、配管は鞘管内を通して所定の場所まで配設される。   In order to configure this wall penetration structure, first, the cylindrical sheath tube guide is disposed in a posture inclined with respect to the wall of the house. In this arrangement, at least a portion of the sheath guide is positioned in an installation hole that penetrates the wall. Next, a sheath tube is penetrated from the one surface side of the wall through a sheath tube guide disposed obliquely with respect to the wall. Accordingly, the sheath pipe is provided through the installation hole along the inclination of the sheath pipe guide and obliquely penetrating the wall. Finally, by inserting a pipe inside the sheath pipe, a wall penetrating structure in which the sheath pipe and the pipe as the wall penetrating pipe are obliquely penetrated with respect to the wall is formed. It is arranged to the place.

この壁貫通構造によれば、鞘管ガイドの傾きを利用してこれとともに設置穴を貫通する鞘管を、無理に曲げることなく壁に斜めに貫通させて、壁に沿って配設できる。したがって、例えば、外壁裏の狭い壁裏空間の内部にも無理なく配設できると共に、この鞘管の内部に通して案内させる配管も無理に曲げることなく配設できる。   According to this wall penetrating structure, the sheath pipe penetrating the installation hole together with the inclination of the sheath pipe guide can be obliquely penetrated through the wall without being forcibly bent and disposed along the wall. Therefore, for example, it can be arranged without difficulty in the narrow wall space behind the outer wall, and a pipe guided through the inside of the sheath pipe can be arranged without being bent excessively.

すなわち、壁貫通配管の壁貫通構造によれば、壁に対して斜めに設けられる筒状の鞘管ガイドに鞘管を通して、壁に対して鞘管を斜めに貫通させ、この鞘管に配管を通したことにより、鞘管を無理に曲げることなく壁に沿わせて配設できるので、例えば狭い壁裏空間の内部に鞘管等を配設するのに有利であるとともに、この鞘管内に通される配管も無理に曲げることなく配設できる。   That is, according to the wall penetration structure of the wall penetration pipe, the sheath pipe is passed through the cylindrical sheath pipe guide provided obliquely with respect to the wall, and the sheath pipe is obliquely penetrated with respect to the wall. Since the sheath tube can be disposed along the wall without forcibly bending it, it is advantageous for disposing the sheath tube or the like in a narrow wall space, for example. Pipes can be arranged without being bent excessively.

そして、このように配管を配設できるので、この配管が送液管であって、そこから液漏れを生じた場合に、配管より漏れた液体を、壁を斜めに貫通した鞘管を通して屋外等に導出できる。   And since the pipe can be arranged in this way, when this pipe is a liquid feeding pipe and a liquid leaks from the pipe, the liquid leaking from the pipe is outdoors through a sheath pipe that obliquely penetrates the wall. Can be derived.

又、以上説明したいずれかの実施形態に記載の壁貫通配管の壁通し具は、住宅の壁を貫通する設置穴に嵌め込む第1筒部と、この第1筒部の内側を閉じる閉塞部と、この閉塞部から斜めに突出して、前記壁を貫通する鞘管が通される筒状の鞘管ガイドとを有することを特徴としている。   Moreover, the wall threading tool of the wall through pipe described in any of the embodiments described above includes a first tube portion that fits into an installation hole that penetrates the wall of the house, and a closing portion that closes the inside of the first tube portion. And a cylindrical sheath tube guide that projects obliquely from the closed portion and through which the sheath tube passes through the wall.

この壁通し具においては、まず、壁を貫通する設置穴に、この壁の一面側もしくは他面側から前記壁貫通配管の壁通し具を嵌め込み設置する。次に、前記他面側もしくは一面側から鞘管を鞘管ガイドに通すことにより壁を斜めに貫通させて配設する。最後に、配設し終わった鞘管の内部に配管を通すことにより、この配管を斜めにして壁に貫通させて、鞘管内を通して所定の場所まで配設する。   In this wall threading tool, first, the wall threading tool of the wall through pipe is fitted and installed in an installation hole penetrating the wall from one side or the other side of the wall. Next, the sheath pipe is passed through the sheath guide from the other side or one side, and the wall is obliquely penetrated. Finally, a pipe is passed through the inside of the sheath pipe that has been disposed, and the pipe is obliquely penetrated through the wall, and is disposed through the sheath pipe to a predetermined place.

この壁貫通配管の壁通し具には、その閉塞部に斜めの筒状の鞘管ガイドが設けられている。この鞘管ガイドに鞘管を通すことにより、鞘管を無理に曲げることなく壁に斜めに貫通させて、壁に沿って配設できる。したがって、例えば、外壁裏の狭い壁裏空間の内部にも無理なく配設できると共に、この鞘管の内部に通して案内させる配管も無理に曲げることなく屋内等へと配設できる。   The wall threading tool of this wall through pipe is provided with an oblique cylindrical sheath guide in the closed portion. By passing the sheath tube through the sheath tube guide, the sheath tube can be obliquely penetrated through the wall without being bent excessively, and disposed along the wall. Therefore, for example, it can be arranged without difficulty in the narrow wall space behind the outer wall, and the piping guided through the inside of the sheath tube can be arranged indoors without being bent excessively.

すなわち、この壁貫通配管の壁通し具によれば、その第1筒部の閉塞部に設けられた斜めの鞘管ガイドに鞘管を通して、壁に対して鞘管を斜めに貫通させることができ、それにより内部に配管が通される鞘管を無理に曲げることなく壁に沿わせて配設できるので、例えば狭い壁裏空間の内部に鞘管等を配設するのに有利であるとともに、この鞘管内に通される配管も無理に曲げることなく配設できる。   That is, according to the wall threading tool of this wall through pipe, the sheath pipe can be passed through the slanted sheath pipe through the slanted sheath guide provided at the closed portion of the first cylindrical section, and the slanted pipe can be penetrated with respect to the wall. Since it can be arranged along the wall without forcibly bending the sheath pipe through which the pipe is passed, for example, it is advantageous for arranging the sheath pipe or the like inside the narrow wall space, The piping passed through the sheath tube can also be arranged without being bent excessively.

又、以上説明したいずれかの実施形態に記載の壁貫通配管の壁通し具は、住宅の壁を貫通する設置穴に嵌め込む第1筒部、この第1筒部と一体に形成されて外側へ張り出す第1フランジ部、前記第1筒部の内側を閉じる閉塞部、この閉塞部から斜めに突出して、前記壁を貫通する鞘管が通される筒状の鞘管ガイドを有した第1壁通し部材と、この第1壁通し部材とは反対側から前記設置穴に嵌め込まれる第2筒部にその外側に張り出す第2フランジ部を設けた第2壁通し部材と、前記両フランジ部で前記壁を挟んで前記第1、第2壁通し部材を連結する連結手段と、を具備したことを特徴としている。   Moreover, the wall threading tool of the wall through pipe described in any of the embodiments described above is a first tube portion that fits into an installation hole that penetrates the wall of the house, and is formed integrally with the first tube portion and outside. A first flange portion projecting out, a closed portion that closes the inside of the first tube portion, and a cylindrical sheath tube guide that projects obliquely from the closed portion and passes through the sheath tube that passes through the wall. A first wall passing member; a second wall passing member provided with a second flange portion projecting outward from a second cylindrical portion fitted into the installation hole from a side opposite to the first wall passing member; and the both flanges And connecting means for connecting the first and second wall passing members with the wall interposed therebetween.

この壁通し具においては、まず、第1、第2の壁通し部材の内の一方を壁の一面側から設置穴に嵌め込んだ後、他方を壁の他面側から設置穴に嵌め込む。この後、第1筒部と第2筒部とを連結手段により連結することで、第1フランジ部及び第2フランジ部で壁をその厚み方向両側から挟み込んで、この発明の壁通し具を設置穴に設置する。次に、前記他面側もしくは一面側から鞘管を鞘管ガイドに通すことにより壁を斜めに貫通させて配設する。最後に、配設し終わった鞘管の内部に配管を通すことにより、この配管を斜めにして壁に貫通させて、鞘管内を通して所定の場所まで配設する。   In this wall threader, first, one of the first and second wall threading members is fitted into the installation hole from one side of the wall, and the other is fitted into the installation hole from the other side of the wall. After that, the wall portion of the present invention is installed by connecting the first tube portion and the second tube portion by connecting means so as to sandwich the wall between the first flange portion and the second flange portion from both sides in the thickness direction. Install in the hole. Next, the sheath pipe is passed through the sheath guide from the other side or one side, and the wall is obliquely penetrated. Finally, a pipe is passed through the inside of the sheath pipe that has been disposed, and the pipe is obliquely penetrated through the wall, and is disposed through the sheath pipe to a predetermined place.

この壁貫通配管の壁通し具には、その閉塞部に斜めの筒状の鞘管ガイドが設けられている。この鞘管ガイドに鞘管を通すことにより、鞘管を無理に曲げることなく壁に斜めに貫通させて、壁に沿って配設できる。したがって、例えば、外壁裏の狭い壁裏空間の内部にも無理なく鞘管を配設できると共に、鞘管の内部に通して案内させる配管も無理に曲げることなく屋内等へと配設できる。   The wall threading tool of this wall through pipe is provided with an oblique cylindrical sheath guide in the closed portion. By passing the sheath tube through the sheath tube guide, the sheath tube can be obliquely penetrated through the wall without being bent excessively, and disposed along the wall. Therefore, for example, a sheath pipe can be disposed without difficulty in the narrow wall space behind the outer wall, and piping guided through the interior of the sheath pipe can be disposed indoors without being bent excessively.

さらに、この壁通し具は壁をその厚み方向両側から挟む第1、第2のフランジ部を有しているため、鞘管ガイドに新規に配管を通すときは勿論のこと、老朽化した配管を新品と交換するときにおいても、配管や鞘管を鞘管ガイドに通す際等に加わる操作力を、配管等を押し込んだり、引き出したりする操作方向の上流側において壁に引掛かっているフランジ部に波及させて壁で分散して支持できるから、配管等の挿通方向下流側に位置された壁通し部材を壁に固定する固定部分に前記操作力が集中し難い。よって、壁通し具が壁から不用意に外れることがないとともに、壁と前記第1、第2両フランジ部との接合が緩むことがなく、したがって、外壁への応用においては防水性が損なわれる等のおそれを低くできる。   In addition, since this wall threading tool has first and second flange portions that sandwich the wall from both sides in the thickness direction, not only when a new pipe is passed through the sheath pipe guide, but also an aged pipe. Even when replacing the pipe with a new one, the operating force applied when the pipe or sheath pipe is passed through the sheath pipe guide, etc., is spread to the flange section caught on the wall on the upstream side in the operation direction of pushing or pulling the pipe etc. Therefore, the operation force is difficult to concentrate on a fixing portion for fixing the wall passing member positioned on the downstream side in the insertion direction of piping or the like to the wall. Therefore, the wall threading tool does not come off from the wall inadvertently, and the joint between the wall and the first and second flange portions does not loosen, and thus the waterproofness is impaired when applied to the outer wall. Etc. can be reduced.

すなわち、この壁貫通配管の壁通し具によれば、第1壁通し部材に設けられた斜めの鞘管ガイドに鞘管を通して、壁を斜めに貫通させることができ、それにより内部に配管が通される鞘管を無理に曲げることなく壁に沿わせて配設できるので、例えば狭い壁裏空間の内部に鞘管等を配設するのに有利であるとともに、この鞘管内に通される配管も無理に曲げることなく配設できる。さらに、壁を挟む第1フランジ部と第2フランジ部とを有していて、これらで鞘管の挿通時や配管の出し入れ時等に加わる操作力を壁で支持させるため、壁から不用意に外れることがないとともに、壁と前記第1、第2両フランジ部との間が緩むおそれを低くできる。   That is, according to the wall threading tool of this wall through pipe, the wall can be penetrated diagonally by passing the sheath pipe through the slanted sheath guide provided in the first wall threading member, thereby allowing the pipe to pass inside. Since it is possible to dispose the sheath tube along the wall without forcibly bending it, it is advantageous to dispose the sheath tube or the like inside the narrow wall space, for example, and the pipe passed through the sheath tube Can be placed without bending. Furthermore, since it has the 1st flange part and 2nd flange part which pinch | interpose a wall and these support the operation force added at the time of insertion of a sheath pipe, the insertion / extraction of piping, etc. with this, carelessly from a wall While not coming off, the risk of loosening between the wall and the first and second flange portions can be reduced.

又、以上説明したいずれかの実施形態に記載の壁貫通配管の壁通し具は、前記連結手段によって前記第1、第2フランジ部間の距離を調節できるようにしたことを特徴としている。   Moreover, the wall threading tool of the wall through pipe described in any of the embodiments described above is characterized in that the distance between the first and second flange portions can be adjusted by the connecting means.

この壁通し具においては、既述の作用効果に加えて、第1筒部と第2筒部とを連結する連結手段の調節により、第1、第2フランジ部間の距離を壁の厚みに適合させることができる。したがって、連結手段の調節の利く範囲内の壁の厚みに適用でき、第1、及び第2筒部の長さの違う何種類もの壁貫通配管の壁通し具を用意する必要がなくなる。   In this wall threading tool, in addition to the effects described above, the distance between the first and second flange portions can be set to the wall thickness by adjusting the connecting means for connecting the first tube portion and the second tube portion. Can be adapted. Therefore, the present invention can be applied to the wall thickness within the range in which the connecting means can be adjusted, and it is not necessary to prepare various kinds of wall through pipes for the wall through pipes having different lengths of the first and second cylindrical portions.

すなわち、この壁貫通配管の壁通し具によれば、請求項3に記載の発明に係る壁貫通配管の壁通し具による効果に加えて、壁を挟む第1、第2フランジ部間の距離を変化させて壁への取付けができるので、第1、第2筒部の長さが異なる何種類もの壁貫通配管の壁通し具を用意する必要がなく、壁の厚みのばらつき等を吸収して用いることができる。   That is, according to the wall threading tool of this wall penetration pipe, in addition to the effect of the wall threading tool of the wall penetration pipe according to the invention of claim 3, the distance between the first and second flange portions sandwiching the wall is set. Since it can be attached to the wall by changing it, it is not necessary to prepare several types of wall through pipes for the wall through pipes with different lengths of the first and second tube parts, and absorbs variations in the wall thickness. Can be used.

又、以上説明したいずれかの実施形態に記載の壁貫通配管の壁通し具は、前記設置穴が前記住宅の壁に対して直交する方向に沿って貫通し、前記設置穴に嵌め込まれた際に鉛直方向に沿う前記第1筒部の幅が前記鞘管の外径より十分大きく形成され、前記鞘管ガイドが前記閉塞部から斜め上方に向かって突出して形成されている。   Further, the wall threading tool of the wall through pipe described in any of the embodiments described above, when the installation hole penetrates along the direction orthogonal to the wall of the house and is fitted into the installation hole The width of the first tube portion along the vertical direction is sufficiently larger than the outer diameter of the sheath tube, and the sheath tube guide is formed to project obliquely upward from the closed portion.

この壁通し具は、住宅の設置穴内に嵌め込まれた際に第1筒部の鉛直方向に沿った幅が、鞘管の外径より十分大きく形成されているので、鞘管が無理に折り曲げられて座屈変形を起さない十分に広い空間を第1筒部内に確保することができる。   Since this wall threading tool is formed so that the width along the vertical direction of the first tube portion is sufficiently larger than the outer diameter of the sheath tube when fitted into the installation hole of the house, the sheath tube is forcibly bent. Thus, a sufficiently wide space that does not cause buckling deformation can be secured in the first tube portion.

したがって、鞘管を無理に曲げることなく壁を貫通させて壁に沿わせて配設することができる。また、鞘管が無理に曲げられることがないため、この鞘管内に容易に配管を通すことができる。   Therefore, the sheath tube can be disposed along the wall by penetrating the wall without forcibly bending the sheath tube. Further, since the sheath tube is not forcibly bent, the pipe can be easily passed through the sheath tube.

また、この壁貫通配管の壁通し具が取り付けられる設置穴が、住宅の壁に対して直交する方向に沿って貫通しているので、屋外から屋内に向うにしたがって上方から下方に向かって傾けて鞘管及び配管を配置する場合でも、雨水などが前記第1筒部の外表面などを伝わって屋内に侵入することを防止できる。   Moreover, since the installation hole to which the wall threading tool of this wall penetration pipe is attached penetrates along the direction orthogonal to the wall of the house, it is inclined downward from above as it goes indoors from the outdoors. Even when the sheath tube and the pipe are arranged, it is possible to prevent rainwater or the like from entering the indoors through the outer surface of the first tube portion.

さらに、この壁貫通配管の壁通し具を壁に設置するには、まず、設置穴に対し屋外側から第1筒部を嵌め込む。この際、第1筒部を閉塞部及び鞘管ガイドが屋外に露出するように嵌め込む。そして、屋内側より第1筒部及び鞘管ガイド内に向って鞘管及び配管を挿入する。鞘管ガイドから屋外に露出した鞘管及び配管の先端部に周知の継手などを介して給湯器を接続する。このように、給湯器と、鞘管及び配管と、を互いに接続する継手が屋外に位置することとなる。このため、たとえ、この継手に水漏れが生じても屋内への浸水を防止することができる。   Furthermore, in order to install the wall through tool of the wall through pipe on the wall, first, the first tube portion is fitted into the installation hole from the outdoor side. At this time, the first tube portion is fitted so that the closed portion and the sheath tube guide are exposed to the outside. And a sheath pipe and piping are inserted toward the 1st cylinder part and a sheath pipe guide from an indoor side. A water heater is connected through a well-known joint or the like to a sheath tube exposed to the outside from the sheath tube guide and the tip of the pipe. Thus, the joint which mutually connects a water heater, a sheath pipe, and piping will be located outdoors. For this reason, even if a water leak occurs in this joint, it is possible to prevent water from entering the room.

すなわち、この壁貫通配管の壁通し具によれば、住宅の鉛直方向に沿う前記第1筒部の幅が前記鞘管の外径より十分大きく形成されており、鞘管が無理に折り曲げられて座屈変形を起さない十分に広い空間を第1筒部内に確保できるので、鞘管を無理に曲げることなく壁を貫通させて壁に沿わせて配設することができる。また、鞘管が無理に曲げられることがないため、この鞘管内に容易に配管を通すことができる。   That is, according to the wall threading device of this wall through pipe, the width of the first tube portion along the vertical direction of the house is formed sufficiently larger than the outer diameter of the sheath tube, and the sheath tube is forcibly bent. Since a sufficiently wide space that does not cause buckling deformation can be secured in the first tube portion, the sheath tube can be disposed along the wall through the wall without forcibly bending the sheath tube. Further, since the sheath tube is not forcibly bent, the pipe can be easily passed through the sheath tube.

また、設置穴が、住宅の壁に対して直交する方向に沿って貫通しているので、屋外から屋内に向うにしたがって上方から下方に向かって傾けて鞘管及び配管が配置された場合でも、雨水などの屋内への侵入を防止できる。   In addition, since the installation hole penetrates along the direction orthogonal to the wall of the house, even when the sheath tube and the pipe are arranged by being inclined downward from above as it goes indoors from the outdoors, Prevents intrusion of rainwater and other indoors.

さらに、鞘管ガイドから屋外に露出した鞘管及び配管の先端部に周知の継手などを介して給湯器を接続することができるので、たとえ、この継手に水漏れが生じても屋内への浸水を防止できる。   Furthermore, since a water heater can be connected to the end of the sheath pipe and piping exposed from the sheath pipe guide to the outside via a well-known joint or the like, even if water leakage occurs in this joint, Can be prevented.

又、以上説明したいずれかの実施形態に記載の壁貫通配管の壁通し具は、前記閉塞部が前記住宅の屋外に露出する前記第1筒部の一端部に設けられ、前記第1筒部の他端部のうち少なくとも前記鞘管ガイドが配置された側の外周に取付けられかつ前記設置穴の穴縁に引掛るフランジ部材を備え、前記第1の筒部の他端部のうち前記鞘管ガイドが配置されていない側の縁部が前記穴縁より設置穴内に位置している。   Moreover, the wall threading tool of the wall through pipe according to any one of the embodiments described above is provided at one end of the first tube portion where the closing portion is exposed to the outside of the house, and the first tube portion A flange member that is attached to an outer periphery of at least the side where the sheath tube guide is disposed and hooks on a hole edge of the installation hole, and the sheath of the other end of the first cylindrical portion The edge on the side where the tube guide is not disposed is located in the installation hole from the hole edge.

この壁通し具は、住宅の設置穴内に嵌め込まれた際に第1筒部の鉛直方向に沿った幅が、鞘管の外径より十分大きく形成されている。このため、鞘管が無理に折り曲げられて座屈変形を起さない十分に広い空間を第1筒部内に確保することができる。さらに、前記第1筒部の屋内側に位置する他端部のうち鞘管ガイドが配されていない側の縁部が穴縁より設置穴内に位置している。   When this wall threading tool is fitted in the installation hole of the house, the width along the vertical direction of the first tube portion is formed sufficiently larger than the outer diameter of the sheath tube. For this reason, it is possible to ensure a sufficiently wide space in the first tube portion in which the sheath tube is forcibly bent and does not cause buckling deformation. Furthermore, the edge part by which the sheath pipe guide is not arrange | positioned among the other end parts located in the indoor side of the said 1st cylinder part is located in an installation hole rather than a hole edge.

したがって、鞘管を無理に曲げることなく壁を貫通させて壁に沿わせて配設することができる。また、鞘管が無理に曲げられることがないため、この鞘管内に容易に配管を通すことができる。   Therefore, the sheath tube can be disposed along the wall by penetrating the wall without forcibly bending the sheath tube. Further, since the sheath tube is not forcibly bent, the pipe can be easily passed through the sheath tube.

また、この壁貫通配管の壁通し具は、雨水などの侵入を防止できるとともに、鞘管及び配管と給湯器とを接続する継手などに水漏れが生じても屋内への浸水を防止できる。   Further, the wall threading tool of this through-wall piping can prevent intrusion of rainwater and the like, and can prevent inundation into the room even if water leakage occurs in the joint connecting the sheath tube and the piping and the water heater.

この壁通し具を壁に取付ける際には、閉塞部及び鞘管ガイドが屋外に露出するように、設置穴に対し屋外側から第1筒部を嵌め込んだ後、第1筒部の他端部にフランジ部材を取付ける。フランジ部材は設置穴の穴縁に引掛った状態となる。このフランジ部材を壁にねじ止め等により固定するのが望ましい。このように、壁通し具は住宅の壁に取付けられる。   When attaching this wall threading tool to the wall, after fitting the first tube portion from the outdoor side to the installation hole so that the blocking portion and the sheath tube guide are exposed to the outside, the other end of the first tube portion Attach the flange member to the part. The flange member is caught on the hole edge of the installation hole. It is desirable to fix the flange member to the wall by screwing or the like. In this way, the wall threader is attached to the wall of the house.

この壁通し具は、鞘管ガイドに新規に鞘管及び配管を通すときは勿論のこと、老朽化した配管などを新品と交換するときにおいても、配管や鞘管を鞘管ガイドに通す際等に加わる操作力を、フランジに波及させて壁で分散して支持できる。   This wall threading tool is used not only when new sheath pipes and pipes are passed through the sheath guides, but also when pipes and sheath pipes are passed through the sheath guides when replacing old pipes with new ones. The operating force applied to the surface can be dispersed and supported by the wall by spreading to the flange.

このため、壁通し具が壁などから不用意に外れることが防止される。したがって、配管の出し入れに拘わらず壁への鞘管の設置状況を確実に保持することができる。   For this reason, it is prevented that a wall threading tool removes carelessly from a wall etc. Therefore, it is possible to reliably maintain the installation state of the sheath tube on the wall regardless of whether the pipe is inserted or removed.

すなわち、この壁貫通配管の壁通し具によれば、加えて、前記第1筒部の屋内側に位置する他端部のうち鞘管ガイドが配されていない側の縁部が設置穴の穴縁より設置穴内に位置しているので、鞘管を無理に曲げることなく壁を貫通させて壁に沿わせて配設することがより容易にできる。また、鞘管が無理に曲げられることがないため、この鞘管内に容易に配管を通すことができる。   That is, according to the wall threading tool of this wall through pipe, in addition, the edge on the side where the sheath tube guide is not arranged in the other end portion located on the indoor side of the first tube portion is the hole of the installation hole. Since it is located in the installation hole from the edge, it can be more easily arranged along the wall through the wall without forcibly bending the sheath tube. Further, since the sheath tube is not forcibly bent, the pipe can be easily passed through the sheath tube.

フランジ部材が設置穴の穴縁に引掛かりかつこのフランジ部材を壁にねじ止め等することによって、壁に取付けることができる。このため、鞘管及び配管を鞘管ガイドに通す際等に加わる操作力を、フランジ部材に波及させて壁で分散して支持できる。このため、壁通し具が壁などから不用意に外れることが防止される。したがって、配管の出し入れに拘わらず壁への鞘管の設置状況を確実に保持することができる。   The flange member can be attached to the wall by hooking on the edge of the installation hole and screwing the flange member to the wall. For this reason, the operating force applied when the sheath tube and the pipe are passed through the sheath tube guide can be dispersed and supported by the wall by spreading to the flange member. For this reason, it is prevented that a wall threading tool removes carelessly from a wall etc. Therefore, it is possible to reliably maintain the installation state of the sheath tube on the wall regardless of whether the pipe is inserted or removed.
