Description

【０００１】
【発明の属する技術分野】
本発明は、外壁の配管貫通部の止水構造に関するものである。
【０００２】
【従来の技術】
従来、外壁に設けられた貫通孔に配管が貫通され、この配管の外周に保温材が被覆され、さらに外壁の外部側における保温材の外周にラッギング材が囲繞されてなる配管貫通部を止水するための構造として、例えば、ラッギング材と外壁との間がシールされてなるものや、あるいは外壁の貫通孔に鞘管が設けられ、この鞘管外周面と貫通孔内周面との隙間が孔埋されるとともに、ラッギング材と外壁との間がシールされてなるものが知られている。
【０００３】
【発明が解決しようとする課題】
しかしながら、前者の外壁の配管貫通部の止水構造にあっては、ラッキング材の固定が困難であり、またシール材が線状に施されることになるため止水効果の信頼性が劣るという問題がある。一方、後者にあっては、鞘管と貫通孔との隙間の孔埋時にモルタルがうまく充填されず漏水を生ずる虞がある。
【０００４】
本発明は、上記事情に鑑みなされたもので、確実に止水することができるととともに、ラッキング材を固定することができる外壁の配管貫通部の止水構造を提供することを目的とする。
【０００５】
【課題を解決するための手段】
上記目的を達成するために、請求項１に記載の外壁の配管貫通部の止水構造は、外壁に設けられた貫通孔に配管が貫通され、この配管の外周に保温材が被覆され、さらに上記外壁の外部側の上記保温材の外周にラッギング材が囲繞されてなる外壁の配管貫通部の止水構造であって、上記貫通孔のスリーブとして打ち込まれた管部材に、短管が上記外壁の外部側に突出するように嵌入されるとともに、この短管と上記外壁との間がシールされ、さらに上記ラッギング材の基端部が上記短管の外側に配設されるとともに、このラッギング材と上記外壁との間がシールされてなることを特徴とするものである。
【０００６】
請求項１の止水構造は次のようにして設けられる。すなわち、先ず、外壁に貫通孔のスリーブとして管部材を打ち込み、この管部材に短管を外壁の外部側に突出するように嵌入し、この短管と外壁との間をシールする。次いで、管部材に配管を貫通し、この配管の外周を保温材で被覆した後、外壁の外部側の保温材の外周をラッギング材で囲繞するとともに当該ラッギング材の基端部を短管の外側に配設し、このラッギング材と外壁との間をシールする。
【０００７】
請求項１の発明においては、貫通孔に管部材が設置されるとともに、ニ重にシールしているので、確実に止水される。また、ラッギング材の基端部が短管の外側に配設されているので、ラッギング材が固定される。
【０００８】
【発明の実施の形態】
以下、本発明の外壁の配管貫通部の止水構造の一実施の形態を、図面に基づいて説明する。
本実施の形態に係る外壁の配管貫通部の止水構造は、図１に示すように、外壁１に設けられた貫通孔２に、スリーブとして管部材３が打ち込まれている。管部材３は、内面中央部に突起部４ａを有する合成樹脂製のソケット４と、このソケット４に突起部４ａに突き当たるように外壁１の内部側から嵌入された合成樹脂製の調整用短管５とからなるもので、調整用短管５の長さが調整されることにより管部材３の両端は壁１と面一とされている。管部材３のソケット４には、外壁１の外部側からソケット４に突起部４ａに突き当たるように、かつ短管６が外壁１の外部側に突出するように嵌入され接着材で固定されている。短管６と外壁１との間は、シリコン等からなるシール材７によりシールされている。
【０００９】
管部材３には、冷媒配管８（配管）が貫通され、この冷媒配管８の外周には、保温材９が被覆されている。さらに、外壁１の外部側の保温材９の外周には、ラッギング材１０が囲繞され、この管状のラッギング材１０の基端部が短管６の外側に配設されている。ラッギング材１０と外壁１との間は、シリコン等からなるシール材１１によりシールされている。
【００１０】
このような外壁の配管貫通部の止水構造を設けるには、先ず、外壁１に貫通孔２のスリーブとしてソケット４および調整用短管５からなる管部材３を打ち込み、この管部材３のソケット４に外壁１の外部側から短管６を外壁１の外部側に突出するように嵌入して接着材で固定し、この短管６と外壁１との間をシール材７によりシールする。次いで、管部材３に冷媒配管８を貫通し、この冷媒配管８の外周を保温材９で被覆した後、外壁１の外部側の保温材９の外周をラッギング材１０で囲繞するとともに、当該ラッギング材１０の基端部を短管６の外側に配設し、このラッギング材１０と外壁１との間をシール材１１によりシールする。
【００１１】
この止水構造にあっては、外壁１の貫通孔２に管部材３を設置するとともに、短管６と外壁１との間およびラッギング材１０と外壁１との間をシールし２重にシールを行っているので、確実に止水することができる。また、ラッギング材１０の基端部を短管６の外側に配設しているので、ラッギング材１０を固定することができる。
【００１２】
図２は、管部材３の他の例を示す図である。すなわち、管部材３として、外壁１の厚さよりも長いソケット４が用いられる場合には、予め外壁１から突出する部分４Ａが切断されて、ソケット４の長さが外壁１の厚さに合わせられ、その後このソケット４が貫通孔２に打ち込まれて構成される。
【００１３】
【発明の効果】
以上説明したように、請求項１に記載の外壁の配管貫通部の止水構造によれば、外壁の貫通孔に管部材を設置するとともに２重にシールすることにより、確実に止水することができ、またラッギング材の基端部を短管の外側に配設することにより、ラッギング材を固定することができるという効果を奏する。

[Prior art]
Conventionally, a pipe is passed through a through-hole provided in the outer wall, the outer periphery of this pipe is covered with a heat insulating material, and the pipe penetration portion where the lagging material is surrounded by the outer periphery of the heat insulating material on the outer side of the outer wall is water-stopped. For example, a structure in which the gap between the lagging material and the outer wall is sealed, or a sheath tube is provided in the through-hole of the outer wall, and a gap between the outer peripheral surface of the sheath tube and the inner peripheral surface of the through-hole is provided. It is known that the hole is buried and the gap between the lagging material and the outer wall is sealed.
[0003]
[Problems to be solved by the invention]
However, in the former water-stop structure of the pipe penetration part of the outer wall, it is difficult to fix the racking material, and since the sealing material is applied in a linear shape, the reliability of the water-stopping effect is inferior. There's a problem. On the other hand, in the latter case, when the gap between the sheath tube and the through hole is filled, the mortar is not filled well, and there is a risk of water leakage.
[0004]
This invention is made | formed in view of the said situation, and it aims at providing the water stop structure of the piping penetration part of the outer wall which can fix a racking material reliably while being able to stop water reliably.
[0005]

The short tube and the outer wall are sealed, and the base end portion of the lagging material is disposed outside the short tube, and the lagging material is inserted. And the outer wall are sealed.
[0006]
The water stop structure of claim 1 is provided as follows. That is, first, a tube member is driven into the outer wall as a sleeve of a through hole, and a short tube is fitted into the tube member so as to protrude to the outside of the outer wall, and the space between the short tube and the outer wall is sealed. Next, the pipe is passed through the pipe member, and the outer periphery of the pipe is covered with a heat insulating material. Then, the outer periphery of the heat insulating material on the outer side of the outer wall is surrounded by the lagging material, and the proximal end portion of the lagging material is outside the short pipe. And sealing between the lagging material and the outer wall.
[0007]
In the first aspect of the present invention, the pipe member is installed in the through hole and sealed twice so that the water is surely stopped. Further, since the base end portion of the lagging material is disposed outside the short tube, the lagging material is fixed.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, one embodiment of a water stop structure of a pipe penetration part of an outer wall of the present invention is described based on a drawing.
As shown in FIG. 1, in the water stop structure of the pipe penetration portion of the outer wall according to the present embodiment, the pipe member 3 is driven as a sleeve into the through hole 2 provided in the outer wall 1. The pipe member 3 includes a synthetic resin socket 4 having a protrusion 4a at the center of the inner surface, and a synthetic resin adjustment short tube fitted into the socket 4 from the inside of the outer wall 1 so as to abut against the protrusion 4a. The both ends of the pipe member 3 are flush with the wall 1 by adjusting the length of the adjusting short pipe 5. The short tube 6 is fitted into the socket 4 of the tube member 3 so as to abut against the projection 4a from the outer side of the outer wall 1 and is fixed to the socket 4 with an adhesive. . A space between the short tube 6 and the outer wall 1 is sealed with a sealing material 7 made of silicon or the like.
[0009]
A refrigerant pipe 8 (pipe) is passed through the pipe member 3, and a heat insulating material 9 is coated on the outer periphery of the refrigerant pipe 8. Further, a lagging material 10 is surrounded on the outer periphery of the heat insulating material 9 on the outer side of the outer wall 1, and a base end portion of the tubular lagging material 10 is disposed outside the short tube 6. A gap between the lagging material 10 and the outer wall 1 is sealed with a sealing material 11 made of silicon or the like.
[0010]
In order to provide such a water blocking structure for the pipe penetration portion of the outer wall, first, a tube member 3 including a socket 4 and an adjustment short pipe 5 is driven into the outer wall 1 as a sleeve of the through hole 2, and the socket of this tube member 3 is inserted. 4, the short tube 6 is fitted from the outside of the outer wall 1 so as to protrude to the outside of the outer wall 1 and fixed with an adhesive, and the space between the short tube 6 and the outer wall 1 is sealed with a sealing material 7. Next, the refrigerant pipe 8 passes through the pipe member 3, and the outer periphery of the refrigerant pipe 8 is covered with the heat insulating material 9. A base end portion of the material 10 is disposed outside the short tube 6, and a gap between the lagging material 10 and the outer wall 1 is sealed with a sealing material 11.
[0011]
In this water stop structure, the pipe member 3 is installed in the through hole 2 of the outer wall 1, and the gap between the short pipe 6 and the outer wall 1 and between the lagging member 10 and the outer wall 1 are sealed to be double sealed. The water can be surely stopped. Moreover, since the base end part of the lagging material 10 is arrange | positioned on the outer side of the short tube 6, the lagging material 10 can be fixed.
[0012]
FIG. 2 is a view showing another example of the pipe member 3. That is, when a socket 4 longer than the thickness of the outer wall 1 is used as the pipe member 3, the portion 4 </ b> A protruding from the outer wall 1 is cut in advance, and the length of the socket 4 is adjusted to the thickness of the outer wall 1. Thereafter, the socket 4 is driven into the through hole 2 and configured.
[0013]
