Description

この発明は、例えば家屋に設置する空気調和機の冷媒管などの管体を建物壁を貫通して配管する際に使用する配管カバー装置に関する。   The present invention relates to a piping cover device used when piping a pipe body such as a refrigerant pipe of an air conditioner installed in a house, for example, through a building wall.

空気調和機の冷媒管などの管体を建物の室内と室外とに渡って配管する際には、建物壁にスリーブを貫通して据え付け、そのスリーブに管体を通して室内から室外に導出させ、その導出側の管体を配管カバー装置で覆うようにしている。このような配管カバー装置については、特開平５−７９５９６号公報（特許文献１）、特開平７−２８６７４２号公報（特許文献２）、特開２００３−２８６７４７公報（特許文献３）などに開示されている。   When piping a pipe such as a refrigerant pipe of an air conditioner across the building interior and exterior, a sleeve is installed through the wall of the building, and the sleeve is led out of the room through the tubular body. The tube body on the outlet side is covered with a piping cover device. Such a piping cover device is disclosed in JP-A-5-79596 (Patent Document 1), JP-A-7-286742 (Patent Document 2), JP-A 2003-286747 (Patent Document 3), and the like. ing.

建物壁を貫通して管体を配管する際に問題となるのは、建物壁の躯体を貫通する管体挿入用のスリーブ内への雨水の浸透である。このため、特許文献１では建物壁を貫通するスリーブを室外側に向けて下り勾配とし、特許文献２ではスリーブの周縁に沿うように建物壁の外壁部に凹部を形成し、この凹部内にシーリング材を充填するようにし、また特許文献３では配管カバーの下カバーに排水溝を形成するようにしている。
特開平５−７９５９６号公報 特開平７−２８６７４２号公報 特開２００３−２８６７４７公報 A problem in piping the pipe through the building wall is the penetration of rainwater into the tube insertion sleeve that penetrates the building wall housing. For this reason, in Patent Document 1, the sleeve penetrating the building wall is inclined downward toward the outdoor side, and in Patent Document 2, a recess is formed in the outer wall portion of the building wall along the periphery of the sleeve, and sealing is performed in the recess. In addition, in Patent Document 3, a drainage groove is formed in the lower cover of the pipe cover.
JP-A-5-79596 JP-A-7-286742 JP 2003-286747 A

しかしながら、特許文献１のように、スリーブを下り勾配となるように建物壁に据え付ける手段では、スリーブを所定の傾斜角度に保持して建物壁の躯体に組み付けなければならず、その据え付けの管理が面倒で施工能率が低下してしまう。特許文献２ではシーリング材を充填するための凹部を建物壁の外壁部に形成しなければならないため、施工手数がかかり、施工能率が低下してしまう。また、特許文献３では、配管カバーの下カバーに排水溝を形成して下カバーの外周ブッシングと上カバーとの間の隙間に浸透した雨水をその排水溝を通して排出するようにしたものに過ぎず、建物壁のスリーブ内への雨水の浸透を防止することは困難である。   However, as in Patent Document 1, in the means for installing the sleeve on the building wall so as to have a downward slope, the sleeve must be assembled to the building wall housing while maintaining a predetermined inclination angle. Troublesome construction efficiency will be reduced. In patent document 2, since the recessed part for filling with a sealing material must be formed in the outer wall part of a building wall, construction work will start and construction efficiency will fall. Moreover, in patent document 3, the drainage groove is formed in the lower cover of the piping cover, and rainwater that has penetrated into the gap between the outer peripheral bushing of the lower cover and the upper cover is merely discharged through the drainage groove. It is difficult to prevent the penetration of rainwater into the sleeve of the building wall.

この発明はこのような点に着目してなされたもので、その目的とするところは、簡単な構造で建物壁のスリーブ内への雨水の浸透を確実に防止することができる配管カバー装置を提供することにある。   The present invention has been made paying attention to such points, and an object thereof is to provide a piping cover device that can reliably prevent rainwater from penetrating into a sleeve of a building wall with a simple structure. There is to do.

そして、上カバー１２を下カバー１１の上に重ね合わせて押し込むことにより、嵌合壁３０が突壁１８の外周に弾性的に嵌合するとともに嵌合爪３１が嵌合溝１９に弾性的に嵌合し、この嵌合で下カバー１１に対して上カバー１２が一体的に結合し、これら下カバー１１と上カバー１２との間に配管スペース３３が確保されるようになっている。   Then, the upper cover 12 is pushed over the lower cover 11 so that the fitting wall 30 is elastically fitted to the outer periphery of the protruding wall 18 and the fitting claw 31 is elastically fitted into the fitting groove 19. The upper cover 12 is integrally coupled to the lower cover 11 by this fitting, and a piping space 33 is secured between the lower cover 11 and the upper cover 12.

下カバー１１は建物壁１の外壁面に止めねじ３５を介して取り付けられ、この下カバー１１の挿入筒１６が建物壁１の貫通孔７を通してスリーブ８の内周に差し込まれている。そしてこの下カバー１１の上に上カバー１２が装着されている。   The lower cover 11 is attached to the outer wall surface of the building wall 1 via a set screw 35, and the insertion cylinder 16 of the lower cover 11 is inserted into the inner periphery of the sleeve 8 through the through hole 7 of the building wall 1. An upper cover 12 is mounted on the lower cover 11.

建物壁１の外壁面を構成する化粧タイル３の厚さは例えば２５ｍｍで、躯体２の厚さは２２０ｍｍとなっている。前記挿入筒１６はスリーブ８の内周面に密に差し込まれ、その差込み代Ｌが例えば３０ｍｍとなっている。そして前記挿入筒１６の外周面には予め接着剤が塗布され、その接着剤を介して前記差込み代Ｌの区間において挿入筒１６の外周面とスリーブ８の内周面とが接着されている。   The thickness of the decorative tile 3 constituting the outer wall surface of the building wall 1 is, for example, 25 mm, and the thickness of the housing 2 is 220 mm. The insertion tube 16 is closely inserted into the inner peripheral surface of the sleeve 8, and its insertion allowance L is, for example, 30 mm. An adhesive is applied to the outer peripheral surface of the insertion tube 16 in advance, and the outer peripheral surface of the insertion tube 16 and the inner peripheral surface of the sleeve 8 are bonded to each other in the section of the insertion allowance L via the adhesive.

一方、建物壁１の内面側つまり室内側においては、貫通孔７内にガイド筒４０が挿入されている。このガイド筒４０は筒体４１と、この筒体４１の一端部に形成されたフランジ部４２とからなり、筒体４１が貫通孔７を通してスリーブ８の内周に差込まれ、フランジ部４２が建物壁１の内面の化粧層５に押し当てられている。なお、このガイド筒４０の室内側開口部には図６に示す室内側キャップ４５を装着してその開口部を密閉することができるようになっている。   On the other hand, a guide tube 40 is inserted into the through hole 7 on the inner surface side of the building wall 1, that is, on the indoor side. The guide tube 40 includes a tube body 41 and a flange portion 42 formed at one end of the tube body 41. The tube body 41 is inserted into the inner periphery of the sleeve 8 through the through hole 7, and the flange portion 42 is It is pressed against the decorative layer 5 on the inner surface of the building wall 1. Note that an indoor side cap 45 shown in FIG. 6 can be attached to the indoor side opening of the guide tube 40 so that the opening can be sealed.

空気調和機の冷媒管などの管体ａを配管する際には、下カバー１１から上カバー１２及び室外側キャップ２４を取り外し、また室内側のガイド筒４０から室内側キャップ４５を取り外し、この状態において、室内側から管体ａをガイド筒４０の筒体４１、スリーブ８、下カバー１１の挿入筒１６を通して室外側に導出させる。この際、下カバー１１から取り外したキャップ２４は、図５（Ａ）に示すようにフック２６の内側に差込んで保管する。そして室外側に導出させた管体ａを下カバー１１に沿って下方に折り曲げ、下カバー１１の下方に引き延ばす。   When piping a pipe body a such as a refrigerant pipe of an air conditioner, the upper cover 12 and the outdoor cap 24 are removed from the lower cover 11, and the indoor cap 45 is removed from the indoor guide tube 40. , The tubular body a is led out from the indoor side to the outdoor side through the cylindrical body 41 of the guide cylinder 40, the sleeve 8, and the insertion cylinder 16 of the lower cover 11. At this time, the cap 24 removed from the lower cover 11 is inserted and stored inside the hook 26 as shown in FIG. Then, the tubular body a led out to the outdoor side is bent downward along the lower cover 11 and extended below the lower cover 11.

この後、下カバー１１の上に上カバー１２を重ね合わせ、嵌合爪３１を嵌合溝１９に嵌合して下カバー１１に上カバー１２を取り付け、この上カバー１２で前記管体ａを覆う。また、管体ａの下カバー１１の下側に延びた部分には、配管カバー５０を取り付けて覆う。これにより管体ａの配管の施工が完了する。   Thereafter, the upper cover 12 is overlaid on the lower cover 11, the fitting claw 31 is fitted into the fitting groove 19, and the upper cover 12 is attached to the lower cover 11. cover. Further, a pipe cover 50 is attached and covered to a portion extending to the lower side of the lower cover 11 of the tube body a. Thereby, the construction of the piping of the tubular body a is completed.

降雨時には建物壁１の外壁面を伝わって雨水が流れ落ち、この雨水が下カバー１１と建物壁１外壁面との間に浸入することがある。しかしながら、下カバー１１の背面側に挿入筒１６が一体に突出形成され、この挿入筒１６がスリーブ８の内側に差込まれ、さらにその挿入筒１６とスリーブ８との差込み代Ｌの区間が接着剤で接着されており、このため雨水が下カバー１１と外壁面との間に浸入しても、その雨水は挿入筒１６の外周面側に伝わるだけで、挿入筒１６の外周からスリーブ８内に浸入するようなことがない。   When it rains, rainwater flows down the outer wall surface of the building wall 1, and this rainwater may enter between the lower cover 11 and the outer wall surface of the building wall 1. However, an insertion cylinder 16 is integrally formed on the back side of the lower cover 11, the insertion cylinder 16 is inserted into the sleeve 8, and a section of the insertion allowance L between the insertion cylinder 16 and the sleeve 8 is bonded. For this reason, even if rainwater enters between the lower cover 11 and the outer wall surface, the rainwater is only transmitted to the outer peripheral surface side of the insertion tube 16, and the inside of the sleeve 8 is inserted from the outer periphery of the insertion tube 16. There is no such thing as intrusion.

このように、この発明の配管カバー装置によれば、簡単な構造で建物壁１のスリーブ８内への雨水の浸透を確実に防止することができる。   Thus, according to the piping cover device of the present invention, it is possible to reliably prevent the penetration of rainwater into the sleeve 8 of the building wall 1 with a simple structure.

ところで、空気調和機の撤去などでスリーブ８内から管体ａを抜き取ったときには、図５（Ａ）に示すように、下カバー１１の挿入口１５にキャップ２４を装着して挿入口１５を密閉する。この際、キャップ２４は図５（Ｂ）に示すように、下カバー１１のフック２６に掛け止められて保管されており、このためキャップ２４が紛失するようなことがなく、その使用時にキャップ２４の所在がすぐわかり、まごつくことなくキャップ２４を挿入口１５に装着することができる。   By the way, when the tube body a is removed from the sleeve 8 by removing the air conditioner or the like, the cap 24 is attached to the insertion port 15 of the lower cover 11 to seal the insertion port 15 as shown in FIG. To do. At this time, as shown in FIG. 5 (B), the cap 24 is stored by being hooked to the hook 26 of the lower cover 11, so that the cap 24 is not lost, and the cap 24 is not used at the time of use. The cap 24 can be attached to the insertion port 15 without being confused.
