Description
本発明は、壁部に設けられる貫通孔に対して取り付ける壁部貫通部材等に関するものである。 The present invention relates to a wall portion penetrating member attached to a through hole provided in a wall portion.
従来、例えば屋外に設置される給湯器等に接続される配管を屋内に引き込む際には、屋外と屋内を区分けする壁部に配管を挿通させて設置する必要がある。貫通部からの水の浸入を防止する必要があることから、貫通部には壁部貫通部材が設けられる。 Conventionally, for example, when a pipe connected to a hot water heater or the like installed outdoors is drawn indoors, it is necessary to install the pipe through a wall section that separates the outdoors from the indoors. Since it is necessary to prevent intrusion of water from the penetration part, a wall part penetration member is provided in the penetration part.
このような壁部貫通部材としては従来エルボ型の継手配管を用い、当該継手配管を壁部に貫通させ、継手配管の両端にそれぞれ、配管を接続する方法が一般的である。 As such a wall part penetrating member, a conventional elbow type joint pipe is generally used, the joint pipe is passed through the wall part, and pipes are respectively connected to both ends of the joint pipe.
また、壁部貫通部材として、例えば、筒状の鞘管垣外を壁に対して斜めになるように配置し、鞘管ガイドの傾き方向に鞘管を貫通させ、鞘管内部に配管を貫通する配管の壁部貫通構造がある(特許文献1)。 Further, as the wall portion penetrating member, for example, the outside of the cylindrical sheath pipe wall is disposed so as to be inclined with respect to the wall, the sheath pipe is penetrated in the inclination direction of the sheath pipe guide, and the pipe is penetrated inside the sheath pipe. There is a pipe wall penetration structure (Patent Document 1).
しかし、特許文献1のような壁部貫通構造は壁部に壁通し具を固定するための部材の数が多く、形状も複雑であるため、壁面において設置できる箇所が限定されてしまう。そのため壁部貫通部材の用途も限定されてしまう。 However, the wall-penetrating structure as in Patent Document 1 has a large number of members for fixing the wall threading tool to the wall and has a complicated shape, so that the places where the wall can be installed on the wall are limited. Therefore, the use of the wall portion penetrating member is also limited.
また、特許文献1のような壁貫通配管の壁通し具は鞘管ガイドの傾き方向に鞘管を貫通させ、鞘管内部に配管を貫通することから、設置角度によっては壁通し具の鉛直方向の寸法が大きくなってしまい、設置自由度が低い。 Moreover, since the wall threading tool of wall penetration piping like patent document 1 penetrates a sheath pipe in the inclination direction of a sheath pipe guide, and penetrates piping inside a sheath pipe, depending on an installation angle, the vertical direction of a wall threading tool The size of the is increased, and the degree of freedom of installation is low.
本発明は、このような問題に鑑みてなされたもので、設置が容易で、かつ設置自由度の高い壁部貫通部材、配管の壁部貫通構造を提供する。 The present invention has been made in view of such a problem, and provides a wall part penetrating member and a pipe wall part penetrating structure that are easy to install and have a high degree of freedom in installation.
前述した目的を達成するため、第1の発明は、壁部の貫通孔に設置され、壁部への貫通配管固定に用いられる壁部貫通部材であって、金属製のパイプ部と、前記パイプ部の外周面に接合される金属製のフランジ部材と、前記フランジ部材を前方から貫通するネジと、前記フランジ部材の後方側に突出する部位の前記ネジに設けられる回転規制部材と、前記回転規制部材の後方で前記ネジと螺合する係止部と、前記フランジ部材に設けられる弾性部材および水膨張性部材と、を具備し、前記フランジ部材は、前記パイプ部の外周面に対して略垂直に外方に起立する第2フランジ部と、前記第2フランジ部の基部が前方側に屈曲されて、前記パイプ部に沿って形成され、前記パイプ部の外周面に接合される連結部と、前記第2フランジ部と離隔して設けられ、前記連結部の前端近傍において、前記第2フランジ部と略平行に外方に起立する第1フランジ部とが一体で形成されたもので、前記第1フランジ部の外径は、前記第2フランジ部の外径よりも大きく形成され、前記弾性部材は、前記第1フランジ部の後面に設けられ、前記水膨張性部材は、前記第1フランジ部と前記第2フランジ部との間であって、前記連結部の外周部において、前記第1フランジ部、前記第2フランジ部、および前記連結部によって形成される空間に設けられることを特徴とする壁部貫通部材である。 In order to achieve the above-described object, the first invention is a wall- penetrating member that is installed in a through-hole of a wall and is used for fixing a through-pipe to the wall, comprising a metal pipe and the pipe A metal flange member joined to the outer peripheral surface of the portion, a screw penetrating the flange member from the front, a rotation restricting member provided on the screw at a portion protruding to the rear side of the flange member, and the rotation restricting member A locking portion screwed into the screw behind the member; and an elastic member and a water-expandable member provided on the flange member, wherein the flange member is substantially perpendicular to the outer peripheral surface of the pipe portion. A second flange portion standing outwardly, a base portion of the second flange portion bent forward, formed along the pipe portion, and joined to the outer peripheral surface of the pipe portion; spaced apart from the second flange portion Provided, in the vicinity of the front end of the said connecting portion, in which a first flange portion you standing substantially parallel outwardly from the second flange portion is formed integrally, the outer diameter of the first flange portion, The elastic member is provided on a rear surface of the first flange portion, and the water-expandable member is formed between the first flange portion and the second flange portion. be between, Oite the outer periphery of the connecting portion, the first flange portion, the second flange portion, and wall portions penetrating member, characterized in that provided in the space formed by the connecting portion .
前記フランジ部材の軸方向に対して、前記パイプ部の軸方向がずれて溶接で接合されており、前記パイプ部は、前記フランジ部材に対して斜めに接合されることが望ましい。 It is desirable that the axial direction of the pipe portion is shifted with respect to the axial direction of the flange member and is joined by welding, and the pipe portion is joined obliquely to the flange member.
前記パイプ部が、前方に向かって下方に傾斜するように配置した際、前記フランジ部材の前面には、壁部貫通部材の上下方向が視認可能なマーク部が設けられてもよい。 When the pipe portion is disposed so as to be inclined downward toward the front, a mark portion where the vertical direction of the wall portion penetrating member can be visually recognized may be provided on the front surface of the flange member.
第1の発明によれば、壁部に容易に固定可能な壁部貫通部材を得ることができる。 According to 1st invention, the wall part penetration member which can be easily fixed to a wall part can be obtained.
具体的には、フランジ部材の前方からネジを回転させると、ネジの回転に伴い、係止部が前記Oリングに接触するまでは、係止部が前記ネジの軸方向に移動する。一方、係止部が前記Oリングに接触すると、係止部の一部がパイプ部の外周面に接触するまでは、係止部は前記ネジとともに回転する。さらに係止部を回転させて、係止部の一部がパイプ部の外周面に接触すると、ネジの回転に伴い、係止部が前記Oリングとともにネジの軸方向に移動する。 Specifically, when the screw is rotated from the front of the flange member, the locking portion moves in the axial direction of the screw until the locking portion contacts the O-ring as the screw rotates. On the other hand, when the engaging portion comes into contact with the O-ring, the engaging portion rotates together with the screw until a part of the engaging portion comes into contact with the outer peripheral surface of the pipe portion. When the locking portion is further rotated and a part of the locking portion comes into contact with the outer peripheral surface of the pipe portion, the locking portion moves in the axial direction of the screw together with the O-ring as the screw rotates.
したがって、壁部に壁部貫通部材を取り付ける際に、壁部貫通部材のフランジ部材の前面からネジを締めることによって、第1フランジ部の裏側に配置される係止部と第1フランジ部とで壁部を挟みこむ。つまり、壁部貫通部材の一方の面からだけネジを締めることによって、壁部に壁部貫通部材が固定されるので、取り付けが容易である。 Therefore, when attaching the wall part penetrating member to the wall part, by tightening a screw from the front surface of the flange member of the wall part penetrating member, the locking part and the first flange part arranged on the back side of the first flange part Insert the wall. That is, since the wall portion penetrating member is fixed to the wall portion by tightening the screw only from one surface of the wall portion penetrating member, attachment is easy.
また、ネジは互いに離間する一対のフランジ部を貫通する。したがって、ネジの軸がぶれることを抑制することができる。また、第1フランジ部の後面に弾性部材が設けられるため、壁部貫通部材を壁部に設置した際には、弾性部材によって、第1フランジ部と壁面との隙間が止水される。また、万一水分が第1フランジ部と壁面との間に浸入したとしても、第1フランジ部と第2フランジ部との間の連結部の外周に、水膨張性部材が設けられる。したがって、水分が第2フランジ部よりも後方側に浸入することを確実に防止することができる。 The screw passes through a pair of flange portions that are separated from each other. Therefore, it is possible to prevent the screw shaft from moving. Moreover, since the elastic member is provided on the rear surface of the first flange portion, when the wall portion penetrating member is installed on the wall portion, the gap between the first flange portion and the wall surface is stopped by the elastic member. Moreover, even if moisture permeates between the first flange portion and the wall surface, the water-expandable member is provided on the outer periphery of the connecting portion between the first flange portion and the second flange portion. Therefore, it is possible to reliably prevent moisture from entering the rear side of the second flange portion.
なお、パイプ部材とフランジ部材は金属で成形され、フランジ部材の第1フランジ部、第2フランジ部及び連結部が一体で形成されているため、製造が容易である。また、樹脂製のものと比較して、壁部貫通部材に挿通される管体を流れる流体が高温であるよう場合であっても、適用が可能である。したがって、例えばレンジフードの排気や、浴室暖房の吸排気などにも適用が可能である。 Incidentally, the pipe member and the flange member is formed of metal, the first flange portion of the flange member, the second flange portion and because been formed connecting part integrally, it is easy to manufacture. Moreover, even if it is a case where the fluid which flows through the pipe body penetrated by the wall part penetration member is high temperature compared with the thing made from resin, it is applicable. Therefore, the present invention can be applied to, for example, exhaust of a range hood and intake / exhaust of bathroom heating.
また、フランジ部とパイプ部の軸方向が互いに僅かにずれているため、フランジ部を壁面にまっすぐに配置にした際に、パイプ部を僅かに下方に向けて傾斜させることができる。したがって、パイプ部から壁面の内側に水分が流れ込むことを防止することができる。 Further, since the axial directions of the flange portion and the pipe portion are slightly shifted from each other, the pipe portion can be inclined slightly downward when the flange portion is arranged straight on the wall surface. Therefore, it is possible to prevent moisture from flowing from the pipe portion to the inside of the wall surface.
この際、パイプ部の向きが分かるように、フランジ部にマークを設けることで、パイプ部の向きを容易に視認することができる。したがって、確実にパイプ部が壁面外部に向かって下方に傾斜するように設置することができる。 At this time, by providing a mark on the flange portion so that the orientation of the pipe portion can be understood, the orientation of the pipe portion can be easily visually confirmed. Therefore, it can install reliably so that a pipe part may incline below toward the wall surface exterior.
第2の発明は、第1の発明にかかる壁部貫通部材を用い、壁部に形成された貫通孔に前記壁部貫通部材が設置され、前記第1フランジ部の外径は、前記貫通孔の外径よりも大きく形成され、前記第2フランジ部の外径は、前記貫通孔の内径よりも小さく形成され、前記フランジ部材の後面の前記弾性部材が、前記第1フランジ部と前記壁部の前面との間に設置されて前記壁部の前面に押し付けられ、前記水膨張性部材が、前記連結部の外周部と前記貫通孔の内面との間に設置され、前記係止部が前記貫通孔の外周側に張り出し、前記フランジ部材と前記係止部によって前記壁部を挟み込むことで前記壁部貫通部材が前記壁部に固定されることを特徴とする壁部貫通構造である。 2nd invention uses the wall part penetration member concerning 1st invention, the said wall part penetration member is installed in the through-hole formed in the wall part, and the outer diameter of the said 1st flange part is the said through-hole. The outer diameter of the second flange portion is formed smaller than the inner diameter of the through hole, and the elastic member on the rear surface of the flange member is formed by the first flange portion and the wall portion. Between the front surface of the wall portion and pressed against the front surface of the wall portion, the water-expandable member is disposed between the outer peripheral portion of the connecting portion and the inner surface of the through hole, and the locking portion is The wall penetrating structure is characterized in that the wall penetrating member is fixed to the wall portion by projecting to the outer peripheral side of the through hole and sandwiching the wall portion by the flange member and the locking portion.
第2の発明によれば、第1フランジ部の外径は、貫通孔の外径よりも大きく、第2フランジ部の外径は、貫通孔の内径よりも小さいため、壁部の前面から貫通孔に壁部貫通部材を挿入することができる。このとき、壁部の一方の面からネジを回転させることで、第1フランジ部と外周側に張り出した係止部とによって壁部を挟みこむため、容易に壁部に壁部貫通部材を固定し、壁部に配管を挿通することができる。また、簡易な構造であるため、壁部に対しての設置自由度が高い。さらに、弾性部材が第1フランジ部と壁部の前面との間に設置され、水膨張性部材が連結部の外周部と貫通孔の内面との間に設置されるため、貫通孔と壁部貫通部材との隙間からの水の浸入を防止することができる。 According to the second invention, the outer diameter of the first flange portion is larger than the outer diameter of the through hole, and the outer diameter of the second flange portion is smaller than the inner diameter of the through hole. A wall part penetrating member can be inserted into the hole. At this time, by rotating the screw from one surface of the wall portion, the wall portion is sandwiched between the first flange portion and the engaging portion protruding to the outer peripheral side, so that the wall portion penetrating member is easily fixed to the wall portion. Then, the pipe can be inserted into the wall. Moreover, since it is a simple structure, the installation freedom with respect to a wall part is high. Further, since the elastic member is installed between the first flange portion and the front surface of the wall portion, and the water-expandable member is installed between the outer peripheral portion of the connecting portion and the inner surface of the through hole, the through hole and the wall portion Intrusion of water from the gap with the penetrating member can be prevented.
本発明によれば、設置が容易で、かつ設置自由度の高い壁部貫通部材、配管の壁部貫通構造を提供することができる。
According to the present invention, it is possible to provide a wall part penetrating member and a pipe wall part penetrating structure that are easy to install and have a high degree of freedom of installation.
以下、本発明にかかる壁部貫通部材について説明する。図1(a)は壁部貫通部材1を示す前方斜視図、図1(b)は壁部貫通部材1を示す後方斜視図、図2(a)は壁部貫通部材1を示す正面図、図2(b)は壁部貫通部材1を示す背面図、図3(a)は壁部貫通部材1を示す右側面図、図3(b)は壁部貫通部材1を示す平面図、図3(c)は壁部貫通部材1を示す底面図、図3(d)は壁部貫通部材1を示す左側面図である。 Hereinafter, the wall part penetration member concerning the present invention is explained. 1 (a) is a front perspective view showing the wall penetrating member 1, FIG. 1 (b) is a rear perspective view showing the wall penetrating member 1, and FIG. 2 (a) is a front view showing the wall penetrating member 1. 2 (b) is a rear view showing the wall penetrating member 1, FIG. 3 (a) is a right side view showing the wall penetrating member 1, and FIG. 3 (b) is a plan view showing the wall penetrating member 1. FIG. 3 (c) is a bottom view showing the wall penetrating member 1, and FIG. 3 (d) is a left side view showing the wall penetrating member 1. FIG.
壁部貫通部材1は、主に、フランジ部材3、パイプ部5、弾性部材7、ネジ9、係止部13、水膨張性部材15等から構成される。フランジ部材3およびパイプ部5は、例えばステンレスやアルミニウム等の耐食性の良い金属を適用することができる。 The wall portion penetrating member 1 mainly includes a flange member 3, a pipe portion 5, an elastic member 7, a screw 9, a locking portion 13, a water-expandable member 15, and the like. For the flange member 3 and the pipe portion 5, for example, a metal having good corrosion resistance such as stainless steel or aluminum can be applied.
パイプ部5は、筒状体であり、所定の長さで形成される。パイプ部5の外周面位は、フランジ部材3が溶接等によって接合される。フランジ部材3は、例えばプレス等によって一体で形成され、第1フランジ部3a、第2フランジ部3b等から構成される。フランジ部材3の詳細は後述する。 The pipe part 5 is a cylindrical body and is formed with a predetermined length. The flange member 3 is joined to the outer peripheral surface of the pipe part 5 by welding or the like. The flange member 3 is integrally formed by a press or the like, for example, and includes a first flange portion 3a, a second flange portion 3b, and the like. Details of the flange member 3 will be described later.
図4は、壁部貫通部材1を示す軸方向断面図であり、図2(a)のA−A線断面図である。フランジ部材3の軸方向(図中B)と、パイプ部5の軸方向(図中C)は、ずれている。すなわち、フランジ部材3に対して、パイプ部5は、僅かに傾いて接合される。傾き角度は、軸方向長さ50mmに対して、これと垂直な方向に約1mm程度変位する程度の角度であればよい。 FIG. 4 is a cross-sectional view in the axial direction showing the wall portion penetrating member 1, and is a cross-sectional view taken along the line AA in FIG. The axial direction (B in the figure) of the flange member 3 and the axial direction (C in the figure) of the pipe portion 5 are shifted. That is, the pipe portion 5 is joined to the flange member 3 with a slight inclination. The inclination angle may be an angle that is displaced about 1 mm in a direction perpendicular to the axial length of 50 mm.
なお、壁部貫通部材1は、前方(図中左側であって、第1フランジ部3a側)に向かうにつれて、下方に傾くように使用される。すなわち、壁部貫通部材1の上部側の方が下部側に対して、パイプ部5が前方に張り出す。 The wall penetrating member 1 is used so as to incline downward as it goes forward (on the left side in the drawing and on the first flange portion 3a side). That is, the pipe portion 5 projects forward from the upper side of the wall penetrating member 1 relative to the lower side.
図5は、フランジ部材3近傍の拡大断面図であり、図4のH部拡大図である。第2フランジ部3bは、パイプ部5の軸方向(図中左右方向)に対して略垂直に外方に起立する。第2フランジ部3bの基部(パイプ部5との接触部近傍)は、前方側に屈曲されて、パイプ部5に沿って連結部3cが所定長さ形成される。 FIG. 5 is an enlarged cross-sectional view of the vicinity of the flange member 3, and is an enlarged view of a portion H in FIG. The second flange portion 3b stands outwardly substantially perpendicular to the axial direction (left and right direction in the drawing) of the pipe portion 5. The base portion of the second flange portion 3 b (near the contact portion with the pipe portion 5) is bent forward, and a connecting portion 3 c is formed along the pipe portion 5 with a predetermined length.
連結部3cの前端近傍では、第2フランジ部3bと略平行に第1フランジ部3aが起立する。なお、第1フランジ部3aの外径は、第2フランジ部3bよりも大きい。さらに、第1フランジ部3aの先端部近傍が、壁部貫通部材の1の前方(図中左側)に向けて屈曲される。 In the vicinity of the front end of the connecting portion 3c, the first flange portion 3a stands up substantially parallel to the second flange portion 3b. In addition, the outer diameter of the 1st flange part 3a is larger than the 2nd flange part 3b. Further, the vicinity of the front end portion of the first flange portion 3a is bent toward the front (left side in the figure) of 1 of the wall portion penetrating member.
第1フランジ部3aの後面であって、外周部近傍には、弾性部材7が設けられる。弾性部材7は、例えば発泡体等であり、容易に変形して壁面との隙間を埋めるものである。第1フランジ部3aと第2フランジ部3bとは連結部3cの長さだけ離間して設けられる。連結部3cの外周部(第1フランジ部3a、第2フランジ部3bの間)には、水膨張性部材15が設けられる。 An elastic member 7 is provided on the rear surface of the first flange portion 3a and in the vicinity of the outer peripheral portion. The elastic member 7 is, for example, a foam or the like, and is easily deformed to fill a gap with the wall surface. The first flange portion 3a and the second flange portion 3b are provided apart from each other by the length of the connecting portion 3c. A water-expandable member 15 is provided on the outer peripheral portion of the connecting portion 3c (between the first flange portion 3a and the second flange portion 3b).
なお、フランジ部材3とパイプ部5の外周面との間には、図示を省略したコーキング処理等が施され、止水される。したがって、フランジ部材3とパイプ部5の隙間から水が浸入することがない。 In addition, the caulking process etc. which abbreviate | omitted illustration is performed between the flange member 3 and the outer peripheral surface of the pipe part 5, and water is stopped. Therefore, water does not enter from the gap between the flange member 3 and the pipe portion 5.
フランジ部材3(第1フランジ部3aおよび第2フランジ部3b)を貫通するように、ネジ9が設けられる。ネジ9は、第1フランジ部3aの前面側から挿通されて、第2フランジ部3bを貫通する。なお、図2に示す例では、ネジ9は、フランジ部材3の上下に一対形成されるが、3か所以上であっても良い。 A screw 9 is provided so as to penetrate through the flange member 3 (the first flange portion 3a and the second flange portion 3b). The screw 9 is inserted from the front side of the first flange portion 3a and penetrates through the second flange portion 3b. In the example shown in FIG. 2, a pair of screws 9 are formed above and below the flange member 3, but may be three or more.
第2フランジ部3bよりも後方側に突出する部位のネジ9には、回転規制部材であるOリング11が設けられる。回転規制部材はボルトに対する係止部の、から回りを防止する部材である。なお、本発明においては、回転規制部材とは、リング状の弾性部材を指す。Oリング11よりもさらに後方側のネジ9には、係止部13が螺合する。図2(b)に示すように、係止部13は、通常状態では、正面視において、第1フランジ部3aの投影面から突出することなく、パイプ部5と接触するように畳まれる。 An O-ring 11 that is a rotation restricting member is provided on the screw 9 at a portion protruding rearward from the second flange portion 3b. The rotation restricting member is a member that prevents the locking part from rotating around the bolt. In the present invention, the rotation restricting member refers to a ring-shaped elastic member. The locking portion 13 is screwed onto the screw 9 further on the rear side than the O-ring 11. As shown in FIG. 2B, the locking portion 13 is folded so as to come into contact with the pipe portion 5 without projecting from the projection surface of the first flange portion 3 a in a normal view in a normal state.
図6は、係止部13が外方に開かれた状態を示す図であり、図6(a)は後方斜視図、図6(b)は背面図である。係止部13は、係止部13の一方の端部(ネジ9との螺合部から短い側の端部)近傍がパイプ部5の外周面に接触するまで、回転することができる。係止部13が完全に回転すると、係止部13の他方の端部(ネジ9との螺合部から長い側の端部)が、外側に広がり、正面視において、第1フランジ部3aよりも外方に突出する。なお、係止部13の回転方法については、詳細を後述する。 6A and 6B are diagrams showing a state in which the locking portion 13 is opened outward, FIG. 6A is a rear perspective view, and FIG. 6B is a rear view. The locking portion 13 can rotate until the vicinity of one end of the locking portion 13 (the end on the short side from the screwed portion with the screw 9) contacts the outer peripheral surface of the pipe portion 5. When the locking portion 13 rotates completely, the other end of the locking portion 13 (the end on the longer side from the screwed portion with the screw 9) spreads outward, and in front view, from the first flange portion 3a. Also protrude outwards. In addition, about the rotation method of the latching | locking part 13, a detail is mentioned later.
次に、壁部17への壁部貫通部材1の固定方法について説明する。まず、図7に示すように、係止部13を畳んだ状態(係止部13が第1フランジ部3a外方に突出しないようにした状態)で、壁部17に形成された孔19に壁部貫通部材1を挿入する(図中矢印D方向)。孔19は折り畳まれた状態の係止部13の外接円および第2フランジ部3bよりも大きく、第1フランジ部3aよりも小さい。
Next, the fixing method of the wall part penetration member 1 to the wall part 17 is demonstrated. First, as shown in FIG. 7, in the state in which the locking portion 13 is folded (the locking portion 13 does not protrude outward from the first flange portion 3a), the
なお、前述したように、壁部貫通部材1には上下方向の向きが存在する。すなわち、パイプ部5が前方に向かって下方に向くように壁部貫通部材1を孔19に挿入する。この際、壁部貫通部材1の向きを容易に視認することができるように、フランジ部材3(第1フランジ部3a)の前面に、上下方向を示すマークを設けることが望ましい。このようにすることで、壁部貫通部材1の設置方向を間違えることを防止することができる。
As described above, the wall portion penetrating member 1 has a vertical direction. That is, the wall portion penetrating member 1 is inserted into the
次に、図8(a)に示すように、壁部17の前面側(第1フランジ部3a側)からネジ9を回転させる(図中矢印E方向)。ネジ9を回転させると、係止部13は、ネジ9の回転に伴い、壁部17側に移動する(図中矢印F方向)。この際、係止部13とネジ9との螺合部における摩擦は、係止部13の自重よりも小さいため、係止部13は、回転せず、パイプ部5に沿って移動する。したがって、図8(b)に示すように、係止部13は、畳まれた状態を維持する。 Next, as shown to Fig.8 (a), the screw 9 is rotated from the front side (1st flange part 3a side) of the wall part 17 (arrow E direction of a figure). When the screw 9 is rotated, the locking portion 13 moves to the wall 17 side as the screw 9 rotates (in the direction of arrow F in the figure). At this time, since the friction at the screwed portion between the locking portion 13 and the screw 9 is smaller than the own weight of the locking portion 13, the locking portion 13 does not rotate but moves along the pipe portion 5. Therefore, as shown in FIG.8 (b), the latching | locking part 13 maintains the folded state.
さらにネジ9を回転させると、図9(a)に示すように、係止部13がOリング11に接触する。係止部13がOリング11に接触すると、係止部13はOリング11によって抵抗を受ける。すなわち、壁部17方向への移動(図中矢印F方向)がOリング11によって抵抗を受け、ネジ9に対する係止部13の回転が規制される。したがって、図9(b)に示すように、係止部13は、ネジ9とともに回転する(図中矢印G方向)。この際、前述したように、係止部13の一方の端部がパイプ部5の外周面に接触するまで、係止部13は回転する。 When the screw 9 is further rotated, the locking portion 13 comes into contact with the O-ring 11 as shown in FIG. When the locking portion 13 contacts the O-ring 11, the locking portion 13 receives resistance by the O-ring 11. That is, the movement in the direction of the wall portion 17 (in the direction of arrow F in the figure) receives resistance by the O-ring 11 and the rotation of the locking portion 13 with respect to the screw 9 is restricted. Therefore, as shown in FIG. 9B, the locking portion 13 rotates together with the screw 9 (in the direction of arrow G in the figure). At this time, as described above, the locking portion 13 rotates until one end of the locking portion 13 contacts the outer peripheral surface of the pipe portion 5.
さらにネジ9を回転させると、係止部13はそれ以上回転することができなくなるため、図10(a)に示すように、係止部13はOリング11とともに、壁部17方向に移動する(図中矢印F方向)。係止部13が壁部17の背面と接触すると、係止部13と第1フランジ部3aとで壁部17が挟み込まれる。この際、弾性部材7が完全に潰れるまで、ネジ9を回転させることで、確実に、係止部13と第1フランジ部3aとで壁部17を挟み込む。 When the screw 9 is further rotated, the locking portion 13 cannot be rotated any further, so that the locking portion 13 moves in the direction of the wall portion 17 together with the O-ring 11 as shown in FIG. (Arrow F direction in the figure). When the locking portion 13 comes into contact with the back surface of the wall portion 17, the wall portion 17 is sandwiched between the locking portion 13 and the first flange portion 3a. At this time, the wall portion 17 is securely sandwiched between the locking portion 13 and the first flange portion 3a by rotating the screw 9 until the elastic member 7 is completely crushed.
以上の操作を、上下のネジ9に対して行うことで、図10(b)に示すように、第1フランジ部3aが壁部17に対してまっすぐに固定される。この後、壁部貫通部材1に配管等を挿通することで、施工が完了する。 By performing the above operation on the upper and lower screws 9, the first flange portion 3a is fixed straight to the wall portion 17 as shown in FIG. Then, construction is completed by inserting piping etc. in the wall part penetration member 1. FIG.
このように、本発明によれば、壁部17に壁部貫通部材1を取り付ける際に、壁部17の前方側からネジ9を締めることによって、壁部17に壁部貫通部材1が固定される。このため、壁部17の前面と後面とで作業を行う必要がなく、取り付けが容易である。 Thus, according to the present invention, when attaching the wall penetrating member 1 to the wall portion 17, the wall penetrating member 1 is fixed to the wall portion 17 by tightening the screw 9 from the front side of the wall portion 17. The For this reason, it is not necessary to work on the front surface and the rear surface of the wall portion 17, and attachment is easy.
また、第1フランジ部3aが確実に壁部17の前面に押し付けられる。この際、第1フランジ部3aの後面には弾性部材7が設けられ、弾性部材7が押し潰されることで、壁部17の前面の凹凸を吸収し、壁部17の前面と第1フランジ部3aとの隙間からの水の浸入を防止することができる。 Further, the first flange portion 3 a is reliably pressed against the front surface of the wall portion 17. At this time, the elastic member 7 is provided on the rear surface of the first flange portion 3a, and the elastic member 7 is crushed to absorb the irregularities on the front surface of the wall portion 17, and the front surface of the wall portion 17 and the first flange portion. Intrusion of water from the gap with 3a can be prevented.
また、万一水が弾性部材7を超えて第1フランジ部3aの後方に浸透しても、第1フランジ部3aと第2フランジ部3bとの間には、水膨張性部材15が設けられる。したがって、水膨張性部材15が膨張することで、それ以上の水の浸入を確実に防止することができる。 In addition, even if water penetrates behind the first flange portion 3a beyond the elastic member 7, the water expandable member 15 is provided between the first flange portion 3a and the second flange portion 3b. . Therefore, when the water-expandable member 15 expands, it is possible to reliably prevent further intrusion of water.
また、パイプ部5は、僅かに前方(壁部17の外方)に向かうにつれて下方に向かって傾斜する。したがって、パイプ部5内に浸入した水は、壁部17の前方側に流れ出し、壁部17の後方に流入することを防止することができる。 Moreover, the pipe part 5 inclines below as it goes ahead slightly (outward of the wall part 17). Therefore, the water that has entered the pipe portion 5 can be prevented from flowing out to the front side of the wall portion 17 and flowing into the rear side of the wall portion 17.
また、第1フランジ部3aの前面に、壁部貫通部材1の向き(上下方向)を示すマークが形成されることで、壁部貫通部材1の設置方向を間違えることがない。 Moreover, the installation direction of the wall part penetration member 1 is not mistaken by forming the mark which shows direction (up-down direction) of the wall part penetration member 1 in the front surface of the 1st flange part 3a.
また、Oリング11が設けられることで、係止部13を確実に外方に向けて回転させることができる。なお、壁部貫通部材1を取り外す際には、ネジ9を逆に回転させると、係止部13は畳まれた状態に回転して、後方に移動する。壁部貫通部材1を壁部17から取り出した後、Oリング11の位置を元の位置に戻すことで、再度使用することができる。 Further, by providing the O-ring 11, the locking portion 13 can be reliably rotated outward. In addition, when removing the wall part penetration member 1, if the screw 9 is rotated reversely, the latching | locking part 13 will rotate in the folded state, and will move back. After the wall portion penetrating member 1 is taken out from the wall portion 17, it can be used again by returning the position of the O-ring 11 to the original position.
また、パイプ部5、フランジ部材3は金属製であるため、高温の流体が流れる部位でも使用可能である。また、パイプ部5は管体であり、フランジ部材3もプレスによって容易に製造することができる。また、溶接で接合可能であるため、接合も容易である。なお、前述したように、パイプ部5とフランジ部材3との接触部には、コーキングが施されるため、水の浸入を防止することができる。 Moreover, since the pipe part 5 and the flange member 3 are metal, it can be used also in the site | part through which a high temperature fluid flows. Moreover, the pipe part 5 is a tubular body, and the flange member 3 can also be easily manufactured by pressing. Moreover, since it can join by welding, joining is also easy. As described above, since the caulking is applied to the contact portion between the pipe portion 5 and the flange member 3, it is possible to prevent water from entering.
また、第1フランジ部3aと第2フランジ部3bとを離間させるため、ネジ9を回転させる際に、ネジ9の軸ずれを防止することができる。また、第1フランジ部3aの先端を折り曲げておくことで、第1フランジ部3aの補強効果がある。この際、先端を前方に向けて曲げることで、壁部17と干渉することもない。 Moreover, since the 1st flange part 3a and the 2nd flange part 3b are spaced apart, when rotating the screw 9, the axial shift of the screw 9 can be prevented. Further, by bending the tip of the first flange portion 3a, the first flange portion 3a has a reinforcing effect. At this time, the front end is bent forward so that it does not interfere with the wall portion 17.
