Description

本発明は、壁部に形成された貫通孔と該貫通孔を挿通する配管等の配設部材との間の空間をシールするシール部を備えたシール構造、及び、該シール構造の施工方法に関する。   The present invention relates to a seal structure including a seal portion that seals a space between a through hole formed in a wall portion and an arrangement member such as a pipe that passes through the through hole, and a method for constructing the seal structure. .

従来から、建屋の外壁等を構成する壁部には、建屋の内外に貫通する貫通孔が形成され、この貫通孔に配管等の配設部材を挿通することで建屋の屋外から屋内又は屋内から屋外への流体等の供給や排出を可能としている。この際、貫通孔と配設部材との間は、屋内外の気密性および水密性を確保するために、貫通孔の内周面と配設部材の外周面との間の隙間に弾性体を含むシール部を設けてシール構造を構成している（例えば、特許文献１参照）。   Conventionally, a through-hole that penetrates the inside and outside of the building is formed in the wall portion that constitutes the outer wall of the building, etc., and an installation member such as a pipe is inserted into this through-hole from the outside of the building or indoors The fluid can be supplied and discharged outdoors. At this time, an elastic body is provided between the through hole and the disposing member in a gap between the inner peripheral surface of the through hole and the outer peripheral surface of the disposing member in order to ensure indoor and outdoor airtightness and watertightness. A seal structure is provided by including a seal portion (see, for example, Patent Document 1).

具体的には、図１７に示すように、シール部４は、壁部１に形成された貫通孔２の内周面２ａと配管３の外周面３ａとの間に充填された発泡ウレタンによって形成された充填シール材５と、充填シール材５の屋外側に配置されたシリコンシーラントなどの高伸縮性材料によって形成された伸縮性部材６とを有している。   Specifically, as shown in FIG. 17, the seal portion 4 is formed by urethane foam filled between the inner peripheral surface 2 a of the through hole 2 formed in the wall portion 1 and the outer peripheral surface 3 a of the pipe 3. And a stretchable member 6 formed of a highly stretchable material such as a silicone sealant disposed on the outdoor side of the fill sealant 5.

特開昭６２−０４６０７８号公報JP 62-046078 A

ところで、配管３と壁部１とは上述したようなシール部４を介して接続されているため、例えば地震などが発生すると配管３と壁部１との相対的位置関係が変化することがある。即ち、図１３に示すように、例えば、配管３の下方の隙間が小さくなるとともに、配管３の上方の隙間が大きくなる場合がある。   By the way, since the pipe 3 and the wall part 1 are connected via the seal part 4 as described above, for example, when an earthquake or the like occurs, the relative positional relationship between the pipe 3 and the wall part 1 may change. . That is, as illustrated in FIG. 13, for example, the gap below the pipe 3 may be reduced and the gap above the pipe 3 may be increased.

このように、壁部１と配管３とが相対変位すると、図１８に示すように、配管３の下方の充填シール材５が配管３と壁部１によって圧縮されるとともに、配管３の上方の充填シール材５が配管３から離間してしまう。この際、充填シール材５と伸縮性部材６とは全面で接着されているため、圧縮された下方の伸縮性部材６が座屈して伸縮性部材６に亀裂が発生する結果、シール性が低下する虞がある。   Thus, when the wall 1 and the pipe 3 are relatively displaced, as shown in FIG. 18, the filling sealing material 5 below the pipe 3 is compressed by the pipe 3 and the wall 1, and at the top of the pipe 3. The filling sealing material 5 is separated from the pipe 3. At this time, since the filling sealing material 5 and the elastic member 6 are bonded to each other, the compressed lower elastic member 6 is buckled and cracks are generated in the elastic member 6, resulting in a decrease in sealing performance. There is a risk of doing.

本発明は、このような事情を考慮してなされたもので、その目的は、シール性を確保することができるシール構造及びシール構造の施工方法を提供することにある。   The present invention has been made in consideration of such circumstances, and an object of the present invention is to provide a seal structure and a construction method of the seal structure that can ensure sealing performance.

上記課題を解決するために、本発明は以下の手段を提供している。
即ち、本発明のシール構造は、屋内側と屋外側とにわたって貫通孔が形成された壁部と、前記貫通孔を挿通する配設部材と、前記貫通孔の内周面と前記配設部材との間の空間をシールするシール部とを備え、前記シール部は、前記貫通孔の内周面と前記配設部材との間に充填された充填シール材と、前記貫通孔の内周面と前記配設部材とにわたるように、前記充填シール材の前記屋外側を向く面および屋内側を向く面のうちの少なくとも一方に積層された伸縮性部材と、を備え、該伸縮性部材は、前記貫通孔の径方向における外側に向かうにしたがって前記充填シール材側に向かって延びる第一傾斜部と、該第一傾斜部の前記径方向における一方側に接続されて、前記径方向における外側に向かうにしたがって前記充填シール材と反対側に向かって延びる第二傾斜部と、を有することを特徴とする。 In order to solve the above problems, the present invention provides the following means.
That is, the seal structure of the present invention includes a wall portion in which a through hole is formed between the indoor side and the outdoor side, a disposing member that inserts the through hole, an inner peripheral surface of the through hole, and the disposing member. A sealing portion that seals a space between the sealing member, a sealing material filled between the inner peripheral surface of the through hole and the arrangement member, and an inner peripheral surface of the through hole. A stretchable member laminated on at least one of the surface facing the outdoor side and the surface facing the indoor side of the filling sealing material so as to extend over the arrangement member, the stretchable member, A first inclined portion extending toward the filling sealing material side toward the outer side in the radial direction of the through hole, and connected to one side in the radial direction of the first inclined portion, toward the outer side in the radial direction To the opposite side of the filling sealant And having a, a second inclined portion extending me.

上記構成によれば、壁部と配設部材との相対変位により伸縮性部材が圧縮された場合においても、第一傾斜部および第二傾斜部の部分が曲げ変形することによって相対変位を吸収することができる。   According to the above configuration, even when the elastic member is compressed by the relative displacement between the wall portion and the arrangement member, the first inclined portion and the second inclined portion absorb the relative displacement by bending deformation. be able to.

上記シール構造において、前記径方向における一方側は、前記径方向における内側であることが好ましい。
上記構成によれば、伸縮性部材および充填シール材を、充填シール材側から見て伸縮性部材のある方向に突出した凸形状とすることで、圧縮された伸縮性部材が曲げ変形しながら充填シール材と反対方向に逃げることができる。したがって、伸縮性部材の座屈を回避し易くなる。また、引張り側の伸縮性部材が充填シール材との接着による拘束が弱まり易いため、支点間距離が長くなることで引っ張りによる亀裂や切断の発生を低減し易くなる。 In the seal structure, it is preferable that one side in the radial direction is an inner side in the radial direction.
According to the above configuration, the compressible elastic member is filled while being bent and deformed by forming the elastic member and the filling sealing material into a convex shape protruding in a direction of the elastic member when viewed from the filling sealing material side. It can escape in the opposite direction to the sealing material. Therefore, it becomes easy to avoid buckling of the elastic member. Moreover, since the stretchable elastic member tends to weaken the restraint due to the adhesion with the filling sealing material, the distance between the fulcrums becomes long, so that it becomes easy to reduce the occurrence of cracking and cutting due to the tension.

上記シール構造において、前記径方向における一方側は、前記径方向における外側であることが好ましい。
上記構成によれば、伸縮性部材および充填シール材を、伸縮性部材側から見て充填シール材のある方向に窪んだ凹形状とすることで、圧縮された伸縮性部材が窪んだ凹部に逃げることができる。これによって、伸縮性部材の座屈を回避しやすくなる。 In the sealing structure, it is preferable that one side in the radial direction is an outer side in the radial direction.
According to the above configuration, the stretchable member and the filling sealing material have a recessed shape that is recessed in the direction of the filling sealing material when viewed from the stretchable member side, so that the compressed elastic member escapes into the recessed recess. be able to. This makes it easier to avoid buckling of the elastic member.

上記シール構造において、前記伸縮性部材は、前記第一傾斜部および前記第二傾斜部の少なくとも一方を複数有し、これら第一傾斜部および第二傾斜部は、前記径方向において交互に接続されていることが好ましい。
上記構成によれば、伸縮性部材が径方向において交互に接続される第一傾斜部および第二傾斜部の少なくとも一方を複数有することで、伸縮性部材の曲げ変形、および、それによる相対変位の吸収を径方向における複数箇所に分散させることができるので、伸縮性部材の座屈をより回避し易くなる。 In the seal structure, the stretchable member includes a plurality of at least one of the first inclined portion and the second inclined portion, and the first inclined portion and the second inclined portion are alternately connected in the radial direction. It is preferable.
According to the above configuration, the elastic member has a plurality of at least one of the first inclined portion and the second inclined portion that are alternately connected in the radial direction, so that bending deformation of the elastic member and relative displacement caused thereby can be reduced. Since absorption can be dispersed at a plurality of locations in the radial direction, it becomes easier to avoid buckling of the elastic member.

上記シール構造において、前記第一傾斜部および前記第二傾斜部は、前記配設部材の軸を中心とした同心円状をなしていることが好ましい。
上記構成によれば、第一傾斜部および第二傾斜部が同心円状をなすことで、圧縮や引張りによって伸縮性部材に加えられる力を周方向において均一に分散させ易くなり、局所的な応力集中による伸縮性部材の座屈を回避し易くなる。また、加工性および施工性を向上させることができる。 In the seal structure, it is preferable that the first inclined portion and the second inclined portion have a concentric shape with the axis of the arrangement member as a center.
According to the above configuration, the first inclined portion and the second inclined portion are concentric, thereby facilitating uniform distribution of the force applied to the elastic member by compression or tension in the circumferential direction, and local stress concentration This makes it easier to avoid buckling of the elastic member. Moreover, workability and workability can be improved.

また、本発明のシール構造の施工方法は、壁部の屋内側および屋外側にわたる貫通孔の内周面と該貫通孔を挿通する配設部材との間の空間に、前記貫通孔の径方向における外側に向かうにしたがって前記壁部の厚さ方向の一方側に延びる第一傾斜板部と、該第一傾斜板部の前記径方向における一方側に接続されて、前記径方向における外側に向かうにしたがって前記壁部の厚さ方向の他方側に延びる第二傾斜板部と、を有する型枠を設置する工程と、前記型枠内に充填シール材を注入する工程と、前記型枠内で前記充填シール材が硬化した後に前記型枠を除去する工程と、硬化した前記充填シール材の余剰部分を除去する工程と、前記充填シール材における前記第一傾斜板部により形成された第一傾斜面および前記第二傾斜板部により形成された第二傾斜面を含む前記充填シール材の面に、前記貫通孔の内周面と前記配設部材とにわたるように伸縮性部材を積層する工程と、を備えることを特徴とする。
上記方法によれば、上述したシール構造を容易に施工することができる。 Further, the construction method of the seal structure of the present invention is the radial direction of the through hole in the space between the inner peripheral surface of the through hole extending over the indoor side and the outdoor side of the wall part and the disposing member passing through the through hole. A first inclined plate portion extending to one side in the thickness direction of the wall portion as it goes outward, and connected to one side in the radial direction of the first inclined plate portion and going outward in the radial direction A step of installing a mold having a second inclined plate portion extending to the other side of the wall portion in the thickness direction, a step of injecting a filling sealing material into the mold, and in the mold A step of removing the mold after the filling sealing material is hardened, a step of removing an excess portion of the hardened filling sealing material, and a first slope formed by the first inclined plate portion in the filling sealing material. Formed by the surface and the second inclined plate portion The surface of the filling sealing material comprising a second inclined surface has, characterized in that it comprises a laminating stretchable member as the inner peripheral surface of the through-hole and over said deployment member.
According to the said method, the sealing structure mentioned above can be constructed easily.

上記シール構造の施工方法において、前記型枠を設置する工程の前に、前記貫通孔を前記壁部に形成する工程と、前記配設部材を前記貫通孔に挿通する工程と、を備えていてもよい。
上記方法によれば、壁部に対して新たに配設部材をシール性高く挿通させることができる。 In the construction method of the seal structure, the step of forming the through hole in the wall portion and the step of inserting the arrangement member into the through hole are provided before the step of installing the mold. Also good.
According to the above method, the arrangement member can be newly inserted into the wall portion with high sealing performance.

本発明によれば、壁部と配設部材との相対変位により伸縮性部材が圧縮された場合に第一傾斜部および第二傾斜部の部分が曲げ変形することによって相対変位を吸収することができる。したがって、伸縮性部材が座屈してしまうことを避けられるため、シール構造のシール性を確保することができる。   According to the present invention, when the elastic member is compressed by the relative displacement between the wall portion and the arrangement member, the first inclined portion and the second inclined portion can be bent and deformed to absorb the relative displacement. it can. Therefore, since it is possible to avoid the elastic member from buckling, the sealing performance of the seal structure can be ensured.

（第一実施形態）
以下、本発明の第一実施形態のシール構造について図面を参照して詳細に説明する。
図１に示すように、本実施形態のシール構造は、壁部１と、配管（配設部材）３と、シール部４と、を備えている。即ち、建屋等の外壁を構成する壁部１には貫通孔２が形成されている。貫通孔２は壁部１の屋内側である第一の面１ａと屋外側である第二の面１ｂとにわたって貫通している。また、配管３は、この貫通孔２に屋内及び屋外に跨って挿通されている。 (First embodiment)
Hereinafter, a seal structure according to a first embodiment of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the seal structure of the present embodiment includes a wall portion 1, a pipe (arrangement member) 3, and a seal portion 4. That is, the through-hole 2 is formed in the wall part 1 which comprises outer walls, such as a building. The through-hole 2 penetrates over the first surface 1a which is the indoor side of the wall portion 1 and the second surface 1b which is the outdoor side. The pipe 3 is inserted through the through hole 2 indoors and outdoors.

壁部１はコンクリートなどによって形成されており、所定の水圧に耐えられる十分な厚さ寸法とされている。図２に示すように、貫通孔２は、その内径が配管３の外径寸法などの設計仕様に基づいて決定されている断面円形の孔である。配管３は、金属などによって形成されている断面円形の管部材である。配管３は、配管３の軸方向（以下、単に軸方向という）から視て、貫通孔２の略中央に該貫通孔２と同軸に配置されている。なお、配管３は、必ずしも略中央に配置されていなくてもよい。   The wall portion 1 is made of concrete or the like, and has a thickness dimension sufficient to withstand a predetermined water pressure. As shown in FIG. 2, the through hole 2 is a hole having a circular cross section whose inner diameter is determined based on design specifications such as the outer diameter of the pipe 3. The pipe 3 is a pipe member having a circular cross section formed of metal or the like. The pipe 3 is arranged coaxially with the through-hole 2 in the approximate center of the through-hole 2 when viewed from the axial direction of the pipe 3 (hereinafter simply referred to as the axial direction). In addition, the piping 3 does not necessarily need to be arrange | positioned in the approximate center.

貫通孔２と配管３との間には、貫通孔２の内周面２ａと配管３の外周面３ａとの間の空間をシールするシール部４が形成されている。シール部４は、貫通孔２の軸方向屋内側（図１における左側）に充填された充填シール材５と、貫通孔２の軸方向屋外側（図１における右側）に充填された伸縮性部材６とを有している。   Between the through hole 2 and the pipe 3, a seal portion 4 that seals a space between the inner peripheral surface 2 a of the through hole 2 and the outer peripheral surface 3 a of the pipe 3 is formed. The seal part 4 includes a filling sealing material 5 filled on the axially indoor side (left side in FIG. 1) of the through-hole 2 and an elastic member filled on the axially outdoor side (right side in FIG. 1) of the through-hole 2. 6.

充填シール材５としては、配管３の内部を通る流体の温度や建屋内温度等に応じた耐熱性を備えた弾性発泡材が用いられている。この充填シール材５は、貫通孔２の内周面２ａと配管３の外周面３ａとの間に液状で充填された後に硬化させることで、貫通孔２の内周面２ａと配管３の外周面３ａとの間の気密性および水密性を確保する。本実施形態においては、気密性および水密性の確保の観点から、充填シール材５としてウレタン等の弾性発泡材が用いられている。   As the filling sealing material 5, an elastic foam material having heat resistance corresponding to the temperature of the fluid passing through the inside of the pipe 3, the temperature inside the building, or the like is used. The filling sealing material 5 is filled with liquid between the inner peripheral surface 2 a of the through hole 2 and the outer peripheral surface 3 a of the pipe 3 and then cured, so that the inner peripheral surface 2 a of the through hole 2 and the outer periphery of the pipe 3 are filled. Airtightness and watertightness between the surface 3a are ensured. In the present embodiment, an elastic foam material such as urethane is used as the filling sealing material 5 from the viewpoint of ensuring airtightness and watertightness.

充填シール材５の屋外側を向く面は、貫通孔２の径方向（以下、単に径方向という）における外側に位置する第一傾斜面５ａと、その内側に接続される第二傾斜面５ｂとを備えている。
第一傾斜面５ａは、縦断面（配管３の軸線を含む断面）視において、径方向外側に向かうにしたがって屋外側から屋内側に向かって直線状に延びており、換言すれば、壁部１の屋外側である第二の面１ｂから壁部１の厚さ方向（配管３の軸方向）における中央部を向く方向（壁部１の厚さ方向の一方側、ここでは図１における右側から左側を向く方向）に直線状に延びる環状の円錐台面状をなしている。 The surface facing the outdoor side of the filling sealing material 5 includes a first inclined surface 5a located on the outer side in the radial direction of the through hole 2 (hereinafter simply referred to as a radial direction), and a second inclined surface 5b connected to the inner side. It has.
The first inclined surface 5a extends linearly from the outdoor side toward the indoor side as viewed from the longitudinal direction (cross section including the axis of the pipe 3), in other words, the wall 1 Direction from the second surface 1b, which is the outdoor side, to the central portion in the thickness direction of the wall portion 1 (axial direction of the pipe 3) (from one side of the thickness direction of the wall portion 1, here from the right side in FIG. 1) It has an annular frustoconical shape extending linearly in the direction facing the left side.

一方、第二傾斜面５ｂは、縦断面視において、径方向外側に向かうにしたがって屋内側から屋外側に向かって直線状に延びており、換言すれば、壁部１の厚さ方向（配管３の軸方向）における中央部から壁部１の屋外側である第二の面１ｂを向く方向（壁部１の厚さ方向の他方側、ここでは図１における左側から右側を向く方向）に直線状に延びる環状の円錐台面状をなしている。   On the other hand, in the longitudinal sectional view, the second inclined surface 5b extends linearly from the indoor side toward the outdoor side as it goes radially outward. In other words, the thickness direction of the wall portion 1 (pipe 3 Straight line in the direction from the center portion toward the second surface 1b on the outdoor side of the wall portion 1 (the other side in the thickness direction of the wall portion 1, here the direction from the left side to the right side in FIG. 1). An annular frustoconical surface extending in a shape is formed.

即ち、第一傾斜面５ａと第二傾斜面５ｂとでは、径方向外側に向かうにしたがって延びる方向が互いに反対となっている。したがって、第一傾斜面５ａの径方向の内側の端部に第二傾斜面５ｂの径方向の外側の端部が接続されることにより、充填シール材５の屋外側を向く面における第一傾斜面５ａおよび第二傾斜面５ｂの接続部が屋内側から屋外側に向けて突出する凸面状となっている。また、第一傾斜面５ａおよび第二傾斜面５ｂは、貫通孔２または配管３の軸を中心とした同心円状となるように接続されている。なお、接続される径方向位置は、径方向における貫通孔２の内周面２ａと配管３の外周面３ａとのほぼ中間付近が好ましいが、これに限定されるものではない。   That is, in the first inclined surface 5a and the second inclined surface 5b, the directions extending toward the radially outer side are opposite to each other. Therefore, by connecting the radially outer end of the second inclined surface 5b to the radially inner end of the first inclined surface 5a, the first inclined surface on the surface facing the outdoor side of the filling sealing material 5 is provided. The connection part of the surface 5a and the 2nd inclined surface 5b becomes the convex surface shape which protrudes toward the outdoor side from an indoor side. The first inclined surface 5 a and the second inclined surface 5 b are connected so as to be concentric with the through hole 2 or the axis of the pipe 3 as the center. The radial position to be connected is preferably near the middle between the inner peripheral surface 2a of the through hole 2 and the outer peripheral surface 3a of the pipe 3 in the radial direction, but is not limited thereto.

一方、充填シール材５の屋内側を向く面は、径方向に沿った方向に延びる環状かつ平面状の側面５ｃとなっている。なお、側面５ｃは必ずしも径方向に沿った方向に延びる必要はなく、軸方向のいずれかに傾斜していても構わない。また、側面５ｃの形状は、平面形状に限られることはなく、曲面や凹凸面など他の面形状でも構わない。   On the other hand, the surface facing the indoor side of the filling sealing material 5 is an annular and flat side surface 5c extending in the direction along the radial direction. Note that the side surface 5c does not necessarily extend in a direction along the radial direction, and may be inclined in any of the axial directions. Further, the shape of the side surface 5c is not limited to a planar shape, and may be another surface shape such as a curved surface or an uneven surface.

伸縮性部材６は、充填シール材５の屋外側を向く凸形状の面全体にほぼ一定の厚さで積層されるように配置されている。また、伸縮性部材６は、外周側が貫通孔２の内周面２ａに固定されるとともに、内周側が配管３の外周面３ａに固定されている。この伸縮性部材６は、高い伸縮性を有する材料によって形成されている。
また、伸縮性部材６と配管３の外周面３ａとの間、および伸縮性部材６と貫通孔２の内周面２ａとの間には、プライマー７が介在している。換言すれば、伸縮性部材６は、貫通孔２の内周面２ａおよび配管３の外周面３ａに下地としてのプライマー７が塗布された状態で積層されている。 The elastic member 6 is disposed so as to be laminated with a substantially constant thickness on the entire convex surface facing the outdoor side of the filling sealing material 5. The stretchable member 6 has an outer peripheral side fixed to the inner peripheral surface 2 a of the through hole 2 and an inner peripheral side fixed to the outer peripheral surface 3 a of the pipe 3. The stretchable member 6 is made of a material having high stretchability.
Further, a primer 7 is interposed between the elastic member 6 and the outer peripheral surface 3 a of the pipe 3 and between the elastic member 6 and the inner peripheral surface 2 a of the through hole 2. In other words, the elastic member 6 is laminated in a state where the primer 7 as a base is applied to the inner peripheral surface 2 a of the through hole 2 and the outer peripheral surface 3 a of the pipe 3.

伸縮性部材６は、高い伸縮性（弾性）を有するシーリング材であり、本実施形態の伸縮性部材６は、シリコンシーラントによって形成されている。即ち、伸縮性部材６は、施工後において配管３が壁部１に対して相対的に動くことにより、配管３と貫通孔２との距離が変化する場合においても、配管３の動きに対して追従する性能を有している。   The stretchable member 6 is a sealing material having high stretchability (elasticity), and the stretchable member 6 of this embodiment is formed of a silicon sealant. In other words, the elastic member 6 can move against the movement of the pipe 3 even when the distance between the pipe 3 and the through hole 2 changes due to the movement of the pipe 3 relative to the wall 1 after construction. Has the ability to follow.

伸縮性部材６は、充填シール材５の屋外側を向く凸面全体にわたって積層された第一傾斜部６ａおよび第二傾斜部６ｂを有している。
第一傾斜部６ａは、充填シール材５の第一傾斜面５ａと同様に、縦断面視において、径方向外側に向かうにしたがって屋外側から屋内側に向かって直線状に延びており、換言すれば、充填シール材５側に向かって直線状に延びる環状の円錐台状をなしている。
また、第二傾斜部６ｂは、充填シール材５の第二傾斜面５ｂと同様に、縦断面視において、径方向外側に向かうにしたがって屋内側から屋外側に向かって直線状に延びており、換言すれば、充填シール材５とは反対側に向かって直線状に延びる環状の円錐台状をなしている。
即ち、第一傾斜部６ａと第二傾斜部６ｂとでは、径方向外側に向かうにしたがって延びる方向が互いに反対となっている。したがって、第一傾斜部６ａの径方向の内側の部分に第二傾斜部６ｂの径方向の外側の部分が接続されることにより、伸縮性部材６の径方向中間部（第一傾斜部６ａと第二傾斜部６ｂの接続部）が屋内側から屋外側に向けて突出する凸形状となっている。 The stretchable member 6 has a first inclined portion 6 a and a second inclined portion 6 b that are stacked over the entire convex surface facing the outdoor side of the filling sealing material 5.
Similarly to the first inclined surface 5a of the filling sealing material 5, the first inclined portion 6a extends linearly from the outdoor side toward the indoor side in the longitudinal sectional view, in other words, in other words, For example, it has an annular truncated cone shape extending linearly toward the filling sealing material 5 side.
Further, the second inclined portion 6b extends linearly from the indoor side toward the outdoor side in the longitudinal cross-sectional view, like the second inclined surface 5b of the filling sealing material 5, as it goes radially outward. In other words, it has an annular truncated cone shape that extends linearly toward the side opposite to the filling sealing material 5.
That is, in the first inclined portion 6a and the second inclined portion 6b, the directions extending toward the radially outer side are opposite to each other. Therefore, by connecting the radially outer portion of the second inclined portion 6b to the radially inner portion of the first inclined portion 6a, the radial intermediate portion (the first inclined portion 6a and the first inclined portion 6a) is connected. The connecting portion of the second inclined portion 6b has a convex shape protruding from the indoor side toward the outdoor side.

また、第一傾斜部６ａおよび第二傾斜部６ｂは、貫通孔２または配管３の軸を中心とした同心円状となるように接続された充填シール材５の第一傾斜面５ａおよび第二傾斜面５ｂ上に積層される。したがって、第一傾斜部６ａおよび第二傾斜部６ｂもこれらに対応して自ずと、図２に示すように、貫通孔２または配管３の軸を中心とした同心円状に設けられることとなる。   The first inclined portion 6a and the second inclined portion 6b are the first inclined surface 5a and the second inclined surface of the filling sealing material 5 connected so as to be concentric with the through hole 2 or the axis of the pipe 3 as the center. It is laminated on the surface 5b. Accordingly, the first inclined portion 6a and the second inclined portion 6b are also naturally provided in a concentric manner around the axis of the through hole 2 or the pipe 3 as shown in FIG.

プライマー７は、伸縮性部材６と貫通孔２の内周面２ａとの接着性、および伸縮性部材６と配管３の外周面３ａとの接着性を向上させるために塗布される下地材である。プライマー７は、伸縮性部材６が接着される対象に応じて適宜選択される。例えば、コンクリート製の壁部１に形成された貫通孔２の内周面２ａと伸縮性部材６との間に塗布するプライマー７は、シリコーン変性ウレタン系の樹脂を酢酸ブチルの溶剤で溶解させたプライマー７（例えば、モメンティブ社、トスプライムＣ（登録商標））が好ましい。   The primer 7 is a base material applied to improve the adhesiveness between the elastic member 6 and the inner peripheral surface 2 a of the through hole 2 and the adhesiveness between the elastic member 6 and the outer peripheral surface 3 a of the pipe 3. . The primer 7 is appropriately selected according to the object to which the stretchable member 6 is bonded. For example, the primer 7 applied between the inner peripheral surface 2a of the through hole 2 formed in the concrete wall 1 and the stretchable member 6 is obtained by dissolving a silicone-modified urethane resin with a solvent of butyl acetate. Primer 7 (for example, Momentive, Tosprime C (registered trademark)) is preferred.

また、金属製の配管３の外周面３ａと伸縮性部材６との間に塗布するプライマー７は、シラン系の樹脂をアセトン、ＩＰＡ、およびトルエンからなる溶剤で溶解させたプライマー７(例えば、モメンティブ社、トスプライムＤ（登録商標））が好ましい。
また、伸縮性部材６と貫通孔２の内周面２ａとの接着性、および、伸縮性部材６と配管３の外周面３ａとの接着性のうちの一方、又は両方が十分であれば、プライマー７を省略することができる。 The primer 7 applied between the outer peripheral surface 3a of the metal pipe 3 and the stretchable member 6 is a primer 7 in which a silane resin is dissolved with a solvent composed of acetone, IPA, and toluene (for example, momentary Company, Tosprime D®) is preferred.
Moreover, if one or both of the adhesiveness between the elastic member 6 and the inner peripheral surface 2a of the through hole 2 and the adhesiveness between the elastic member 6 and the outer peripheral surface 3a of the pipe 3 are sufficient, Primer 7 can be omitted.

さらに、配管３の材質は金属に限ることはなく、塩化ビニールなどの樹脂や、コンクリートを採用することもできる。例えば、配管３として塩化ビニールを用いる場合、配管３と伸縮性部材６との間のプライマー７は樹脂と伸縮性部材６との接着性、耐久性を向上させるような成分とする必要がある。   Furthermore, the material of the pipe 3 is not limited to metal, and resin such as vinyl chloride or concrete can be employed. For example, when vinyl chloride is used as the pipe 3, the primer 7 between the pipe 3 and the stretchable member 6 needs to be a component that improves the adhesion and durability between the resin and the stretchable member 6.

次に、本実施形態のシール構造の施工方法について説明する。
まず、図３に示すように、壁部１に屋内側の第一の面１ａおよび屋外側の第二の面１ｂにわたって貫通する断面円形状の貫通孔２を形成する（工程１）。
そして、貫通孔２の略中心位置に断面円形状の配管３を挿通させる（工程２）。 Next, the construction method of the seal structure of this embodiment will be described.
First, as shown in FIG. 3, a through-hole 2 having a circular cross section is formed in the wall portion 1 so as to penetrate through the indoor first surface 1a and the outdoor second surface 1b (step 1).
Then, the pipe 3 having a circular cross section is inserted through the substantially central position of the through hole 2 (step 2).

次いで、図４に示すように、配管３の外周面３ａと貫通孔２の内周面２ａとの間の空間における屋内側の部分に充填シール材５を充填するための型枠１０を設置する。この際、型枠１０は、屋外側型枠１１、屋内側型枠１２、湯口１３とで構成されるようにする。また、屋外側型枠１１は、径方向外側に第一傾斜板部１１ａと、その内側に接続される第二傾斜板部１１ｂとを備えるようにする。   Next, as shown in FIG. 4, a mold 10 for filling the filling sealing material 5 is installed in the indoor side portion in the space between the outer peripheral surface 3 a of the pipe 3 and the inner peripheral surface 2 a of the through hole 2. . At this time, the mold 10 is composed of an outdoor mold 11, an indoor mold 12, and a gate 13. Moreover, the outdoor side formwork 11 is provided with the 1st inclination board part 11a on the radial direction outer side, and the 2nd inclination board part 11b connected to the inner side.

ここで、第一傾斜板部１１ａは、径方向外側に向かうにしたがって屋外側から屋内側に向かって断面が直線状に延びており、換言すれば、壁部１の屋外側である第二の面１ｂから壁部１の厚さ方向（配管３の軸方向）における中央部を向く方向（壁部１の厚さ方向一方側）に直線状に延びる環状の円錐台部材とする。
一方、第二傾斜板部１１ｂは、径方向外側に向かうにしたがって屋内側から屋外側に向かって断面が直線状に延びており、換言すれば、壁部１の厚さ方向（配管３の軸方向）における中央部から壁部１の屋外側である第二の面１ｂを向く方向（壁部１の厚さ方向他方側）に直線状に延びる環状の円錐台部材とする。 Here, the cross section of the first inclined plate portion 11a extends linearly from the outdoor side toward the indoor side as it goes radially outward. In other words, the second inclined plate portion 11a is the second side that is the outdoor side of the wall portion 1. The annular truncated cone member extends linearly from the surface 1b in the direction (one side in the thickness direction of the wall 1) in the thickness direction of the wall 1 (the axial direction of the pipe 3).
On the other hand, the second inclined plate portion 11b extends in a straight line from the indoor side to the outdoor side as it goes radially outward, in other words, in the thickness direction of the wall portion 1 (the axis of the pipe 3). The circular truncated cone member extends linearly in the direction (the other side in the thickness direction of the wall 1) from the center in the direction) toward the second surface 1b on the outdoor side of the wall 1.

即ち、第一傾斜板部１１ａと第二傾斜板部１１ｂとでは、径方向外側に向かうにしたがって延びる方向が互いに反対となるようにする。したがって、第一傾斜板部１１ａの内側の部分に第二傾斜板部１１ｂの外側の部分を接続することにより、屋外側型枠１１の径方向中間部（第一傾斜板部１１ａと第二傾斜板部１１ｂの接続部）が屋内側から屋外側に向けて突出する凸形状となるように設置する。また、第一傾斜板部１１ａおよび第二傾斜板部１１ｂは、対応する貫通孔２または配管３の軸を中心とした同心円状となるように接続する。なお、これら第一傾斜板部１１ａおよび第二傾斜板部１１ｂを接続する径方向位置は、貫通孔２の内周面２ａと配管３の外周面３ａとのほぼ中間あたりが好ましいが、これに限定されるものではない。また、後述の工程で注入する充填シール材の屋外側を向く面に傾斜面を形成することができれば、屋外側型枠１１の屋外側を向く面は必ずしも傾斜していなくても構わない。   That is, in the first inclined plate portion 11a and the second inclined plate portion 11b, the extending directions are opposite to each other toward the radially outer side. Accordingly, by connecting the outer portion of the second inclined plate portion 11b to the inner portion of the first inclined plate portion 11a, the radial intermediate portion (the first inclined plate portion 11a and the second inclined plate portion 11a) of the outdoor side mold 11 is connected. The connecting part of the plate part 11b is installed so as to have a convex shape protruding from the indoor side toward the outdoor side. Further, the first inclined plate portion 11 a and the second inclined plate portion 11 b are connected so as to be concentric with the corresponding through-hole 2 or the axis of the pipe 3 as the center. The radial position connecting the first inclined plate portion 11a and the second inclined plate portion 11b is preferably about the middle between the inner peripheral surface 2a of the through hole 2 and the outer peripheral surface 3a of the pipe 3. It is not limited. In addition, as long as an inclined surface can be formed on the surface facing the outdoor side of the filling sealing material to be injected in a process described later, the surface facing the outdoor side of the outdoor formwork 11 does not necessarily have to be inclined.

一方、屋内側型枠１２は、径方向に沿った方向に延びる環状の平板部材とする。なお、屋内側型枠１２は必ずしも径方向に沿った方向に延びる必要はなく、軸方向のいずれかに傾斜していても構わない。また、屋内側型枠１２は、平板に限られることはなく、曲面や凹凸面など他の面形状を有しても構わない。
湯口１３は、後述の工程で充填シール材５を注入する際に鉛直方向上方側になるように屋内側型枠１２の径方向外側に設置する。なお、湯口１３は屋内側型枠１２に限らず、屋外側型枠１１に設置してもよいし、あるいは、型枠１０ではなく別の部材、例えば壁部１などに設置してもよい。 On the other hand, the indoor side formwork 12 is an annular flat plate member extending in a direction along the radial direction. In addition, the indoor side formwork 12 does not necessarily need to extend in the direction along the radial direction, and may be inclined in any of the axial directions. Moreover, the indoor formwork 12 is not limited to a flat plate, and may have other surface shapes such as a curved surface and an uneven surface.
The pouring gate 13 is installed on the radially outer side of the indoor side mold 12 so as to be on the upper side in the vertical direction when the filling sealing material 5 is injected in a process described later. The gate 13 is not limited to the indoor mold 12 and may be installed on the outdoor mold 11, or may be installed on another member, such as the wall 1, instead of the mold 10.

なお、上述のような型枠１０を予め一体形成してから配管３と貫通孔２の内周面２ａとの間であって貫通孔２の屋内側の空間に設置してもよいし、あるいは、それぞれ別体で形成した屋外側型枠１１、屋内側型枠１２、湯口１３を予め組み立ててから設置してもよい。また、型枠１０を貫通孔２の屋内側の空間で組み立てながら設置してもよい。さらに、屋外側型枠１１と屋内側型枠１２とを必ずしも一体に組み立てなくても構わない。
また、型枠１０は、後述の工程で注入する充填シール材５が流出しないように貫通孔２の内周面２ａおよび配管３の外周面３ａの寸法形状に対応した寸法形状とし当接させる（工程３）。 In addition, after integrally forming the above-described formwork 10 in advance, it may be installed in the space on the indoor side of the through hole 2 between the pipe 3 and the inner peripheral surface 2a of the through hole 2, or Alternatively, the outdoor-side mold 11, the indoor-side mold 12, and the gate 13 formed separately may be installed after being assembled in advance. Alternatively, the mold 10 may be installed while being assembled in the space on the indoor side of the through hole 2. Furthermore, the outdoor side formwork 11 and the indoor side formwork 12 do not necessarily have to be assembled together.
Further, the mold 10 is brought into contact with a dimensional shape corresponding to the dimensional shape of the inner peripheral surface 2a of the through-hole 2 and the outer peripheral surface 3a of the pipe 3 so that the filling sealing material 5 to be injected in a process described later does not flow out ( Step 3).

次いで、図５に示すように、型枠１０内に湯口１３を介して液体状の充填シール材５を、配管３の外周面３ａと貫通孔２の内周面２ａとの間であって貫通孔２の屋内側の空間が充填シール材５で満たされるように充填する。なお、この空間内（型枠１０内）に空気が残らないように空気抜き孔（不図示）を型枠１０の鉛直方向上方側で湯口１３とは反対側の位置に設けておくとよい（工程４）。
次いで、図６に示すように、所定時間が経過し、注入した充填シール材５が硬化して固体状となった後、型枠１０を全て除去する。これにより、配管３と貫通孔２の内周面２ａとの間であって貫通孔２の屋内側の空間には硬化した充填シール材５のみが残る（工程５）。
次いで、硬化した充填シール材５のうち湯口１３や空気抜き孔の周りに残存しているバリ５ｄ（図６参照）などの余計な部分を除去する。これにより、図７に示すように、第一傾斜板部１１ａの屋内側面により形成された第一傾斜面５ａ、第二傾斜板部１１ｂの屋内側面により形成された第二傾斜面５ｂ、および、屋内側型枠１２の屋外側面により形成された側面５ｃを有する充填シール材５の状態となる（工程６）。 Next, as shown in FIG. 5, the liquid filling sealing material 5 is passed through the mold 10 through the gate 13 between the outer peripheral surface 3 a of the pipe 3 and the inner peripheral surface 2 a of the through hole 2. Filling is performed so that the space on the indoor side of the hole 2 is filled with the filling sealing material 5. Note that an air vent (not shown) may be provided at a position on the opposite side of the gate 13 on the upper side in the vertical direction of the mold 10 so that air does not remain in this space (in the mold 10) (process). 4).
Next, as shown in FIG. 6, after a predetermined time elapses, the filled sealing material 5 is hardened and becomes solid, and then the mold 10 is completely removed. As a result, only the hardened sealing material 5 remains in the space on the indoor side between the pipe 3 and the inner peripheral surface 2a of the through hole 2 (step 5).
Next, unnecessary portions such as burrs 5 d (see FIG. 6) remaining around the gate 13 and the air vent hole are removed from the cured filling sealing material 5. Thereby, as shown in FIG. 7, the first inclined surface 5a formed by the indoor side surface of the first inclined plate portion 11a, the second inclined surface 5b formed by the indoor side surface of the second inclined plate portion 11b, and It will be in the state of the filling sealing material 5 which has the side surface 5c formed by the outdoor side surface of the indoor side mold 12 (process 6).

次いで、図８に示すように、プライマー７を貫通孔２の内周面２ａの伸縮性部材６施工部、および配管３の外周面３ａの伸縮性部材６施工部の全周にわたって塗布する。そして、第一傾斜面５ａと第二傾斜面５ｂにより径方向中間部が屋外側に向けて突出した凸形状となった充填シール材５の屋外側を向く面上に、貫通孔２の内周面２ａと配管３の外周面３ａとにわたってほぼ一定の厚さで積層されるように伸縮性部材６を施工する。この際、伸縮性部材６やプライマー７はヘラやハケ、スプレーなどを用いて塗布してもよいし、あるいは、予め成型しておいた伸縮性部材６を充填シール材５の屋外側を向く面に接着するなど他の方法を用いて積層させても構わない。そして、所定時間が経過すると、第一傾斜部６ａと第二傾斜部６ｂにより径方向中間部が屋外側に向けて突出した凸形状となった伸縮性部材６が硬化することによって、シール部４およびシール構造が完成する（工程７）。   Next, as shown in FIG. 8, the primer 7 is applied over the entire circumference of the stretchable member 6 construction portion on the inner peripheral surface 2 a of the through hole 2 and the stretchable member 6 construction portion on the outer peripheral surface 3 a of the pipe 3. And the inner periphery of the through-hole 2 on the surface which faces the outdoor side of the filling sealing material 5 which became the convex shape which the radial direction intermediate part protruded toward the outdoor side by the 1st inclined surface 5a and the 2nd inclined surface 5b The stretchable member 6 is constructed so as to be laminated with a substantially constant thickness over the surface 2 a and the outer peripheral surface 3 a of the pipe 3. At this time, the elastic member 6 and the primer 7 may be applied using a spatula, a brush, a spray or the like, or the surface of the elastic member 6 that has been molded in advance facing the outdoor side of the filling sealing material 5. You may laminate | stack using other methods, such as adhere | attaching. And when predetermined time passes, the elastic part 6 which became the convex shape which the radial direction intermediate part protruded toward the outdoor side by the 1st inclination part 6a and the 2nd inclination part 6b hardens | cures, and the seal | sticker part 4 And the seal structure is completed (step 7).

なお、貫通孔２のない壁部１に対して新たに本発明のシール構造を設ける場合は、上述の工程１から工程７の順で施工すればよい。一方、配管３を挿通させていない貫通孔２を有する壁部１を用いて本発明のシール構造を新たに設ける場合は、貫通孔２に配管３を挿通させる工程２から施工すればよい。また、既に配管３を挿通させた貫通孔２を有する壁部１に本発明のシール構造を新たに設ける場合は、型枠１０を設置する工程３から施工すればよいし、あるいは、既設のシール構造を補修する場合は、既設のシール構造を除去した後、工程３から施工すればよい。   In addition, what is necessary is just to construct in order of the above-mentioned process 1 to the process 7, when providing the sealing structure of this invention with respect to the wall part 1 without the through-hole 2 newly. On the other hand, when the seal structure of the present invention is newly provided using the wall portion 1 having the through hole 2 through which the pipe 3 is not inserted, the construction may be performed from the step 2 in which the pipe 3 is inserted into the through hole 2. Moreover, when newly providing the sealing structure of this invention in the wall part 1 which has the through-hole 2 which has already penetrated the piping 3, what is necessary is just to construct from the process 3 which installs the formwork 10, or an existing seal | sticker In the case of repairing the structure, the existing seal structure is removed, and then construction is performed from step 3.

次に、本実施形態のシール構造の作用について説明する。
図９に示すように、例えば、地震の発生などによって壁部１の貫通孔２と配管３との相対的位置関係が変動した場合、即ち、図９の配管３の下方に見られるように、壁部１の貫通孔２と配管３との相対変位により、貫通孔２の内周面２ａと配管３の外周面３ａとが接近して充填シール材５および伸縮性部材６が圧縮された場合、充填シール材５は押しつぶされて樽状に丸く膨らむように変形する。したがって、第一傾斜面５ａおよび第二傾斜面５ｂからなる充填シール材５の屋外側を向く面も、側面５ｃからなる充填シール材５の屋内側を向く面も同様に丸く変形する。 Next, the operation of the seal structure of this embodiment will be described.
As shown in FIG. 9, for example, when the relative positional relationship between the through hole 2 of the wall portion 1 and the pipe 3 varies due to the occurrence of an earthquake, that is, as seen below the pipe 3 in FIG. 9, When the inner peripheral surface 2a of the through-hole 2 and the outer peripheral surface 3a of the pipe 3 approach each other due to the relative displacement between the through-hole 2 and the pipe 3 in the wall portion 1, and the filling sealing material 5 and the elastic member 6 are compressed. The filling sealing material 5 is crushed and deformed so as to swell round like a barrel. Therefore, the surface facing the outdoor side of the filling sealing material 5 composed of the first inclined surface 5a and the second inclined surface 5b and the surface facing the indoor side of the filling sealing material 5 composed of the side surface 5c are similarly deformed to be round.

ここで、本実施形態によれば、充填シール材５および伸縮性部材６には屋外側に突出する凸形状部を設けているので、この凸状に接続された伸縮性部材６の第一傾斜部６ａおよび第二傾斜部６ｂが、充填シール材５の変形に追従するように曲げ変形しながら屋外側に逃げることができる。これにより、充填シール材５および伸縮性部材６が圧縮された場合においても、その相対変位を吸収することができ、伸縮性部材６が座屈破壊されることを回避し易くなるため、シール構造の気密性および水密性を確保することができる。   Here, according to the present embodiment, the filling sealing material 5 and the elastic member 6 are provided with the convex portion protruding to the outdoor side, so the first inclination of the elastic member 6 connected to this convex shape. The portion 6 a and the second inclined portion 6 b can escape to the outdoor side while bending and deforming so as to follow the deformation of the filling sealing material 5. Thereby, even when the filling sealing material 5 and the elastic member 6 are compressed, the relative displacement can be absorbed, and it is easy to avoid the buckling failure of the elastic member 6. Airtightness and watertightness can be ensured.

一方、図９の配管３の上方に見られるように、充填シール材５と伸縮性部材６とが引張りの力を受ける場合は、プライマー７による貫通孔２の内周面２ａおよび配管３の外周面３ａに対する伸縮性部材６の接着性に比較して、充填シール材５に対する伸縮性部材６の接着性が低いので、引っ張られた伸縮性部材６が充填シール材５の屋外側を向く面から剥離することで、支点間距離が長くなり、引っ張りによる亀裂や切断の発生を低減し易くすることができる。
即ち、配管３が貫通孔２の内周面２ａから接近する方向に動いた場合、および離間する方向に動いた場合に、配管３の全周にわたって伸縮性部材６に座屈や亀裂の生じることがないため、シール構造の気密性および水密性を確保することができる。 On the other hand, as seen above the pipe 3 in FIG. 9, when the filling sealing material 5 and the stretchable member 6 receive a tensile force, the inner peripheral surface 2 a of the through hole 2 and the outer periphery of the pipe 3 by the primer 7. Compared to the adhesiveness of the elastic member 6 to the surface 3 a, the adhesiveness of the elastic member 6 to the filling sealing material 5 is low, so that the stretched elastic member 6 is directed from the surface facing the outdoor side of the filling sealing material 5. By peeling, the distance between the fulcrums becomes long, and it is possible to easily reduce the occurrence of cracks and cuts due to pulling.
That is, when the pipe 3 moves in a direction approaching from the inner peripheral surface 2a of the through hole 2 and in a direction away from the inner peripheral surface 2a, the elastic member 6 is buckled or cracked over the entire circumference of the pipe 3. Therefore, the airtightness and watertightness of the seal structure can be ensured.

また、伸縮性部材６と貫通孔２の内周面２ａとの間、および伸縮性部材６と配管３の外周面３ａとの間にはプライマー７が介在しているため、伸縮性部材６が引張りの力を受けた場合においても接着性が維持され、伸縮性部材６との間に隙間が生じることがない。
また、第一傾斜部６ａおよび第二傾斜部６ｂが、貫通孔２または配管３の軸を中心とした同心円状に設けられているため、圧縮や引張りによって伸縮性部材６に加えられる力を周方向において均一に分散させ易くなる。したがって、局所的な応力集中による伸縮性部材６の座屈や亀裂の発生を回避し易くなる。また、充填シール材５や伸縮性部材６の加工性および施工性を向上させることができる。 Further, since the primer 7 is interposed between the elastic member 6 and the inner peripheral surface 2 a of the through hole 2 and between the elastic member 6 and the outer peripheral surface 3 a of the pipe 3, the elastic member 6 is Even when a tensile force is applied, the adhesiveness is maintained, and no gap is generated between the elastic member 6 and the adhesive member.
In addition, since the first inclined portion 6a and the second inclined portion 6b are provided concentrically around the axis of the through hole 2 or the pipe 3, the force applied to the elastic member 6 by compression or tension is It becomes easy to disperse uniformly in the direction. Therefore, it becomes easy to avoid buckling and cracking of the elastic member 6 due to local stress concentration. Moreover, the workability and workability of the filling sealing material 5 and the stretchable member 6 can be improved.

また、本実施形態では、充填シール材５の屋外側に設ける伸縮性部材６としてシリコンシーラントを用いたが、ここに設けられる部材は、高い伸縮性を有し、かつ、気密性および水密性を有する素材であればこれに限ることはない。
例えば、伸縮性部材６として、ポリブタジエン系の液状ゴム１４を採用することができる。液状ゴム１４を施工する場合は、まず、プライマー７処理をした上で液状ゴム１４を充填シール材５の屋外側に施工する。次いで、図１０に示すように、液状ゴム１４が流出しないように、貫通孔２の形状に対応した硬質板１５を屋外側から当接させて、液状ゴム１４の形状を整える。ただし、液状ゴム１４の流動性が高い場合には、硬質板１５を事前に配置して液状ゴム１４の流出を防ぐようにする。そして、液状ゴム１４が硬化した後に硬質板１５を除去することによってシール構造が完成する。 Moreover, in this embodiment, although the silicon sealant was used as the elastic member 6 provided on the outdoor side of the filling sealing material 5, the member provided here has high elasticity, and has airtightness and watertightness. If it is the material which has, it will not be restricted to this.
For example, a polybutadiene-based liquid rubber 14 can be employed as the stretchable member 6. When applying the liquid rubber 14, first, after the primer 7 is processed, the liquid rubber 14 is applied to the outdoor side of the filling sealer 5. Next, as shown in FIG. 10, the shape of the liquid rubber 14 is adjusted by bringing a hard plate 15 corresponding to the shape of the through-hole 2 into contact with the outside so that the liquid rubber 14 does not flow out. However, when the fluidity of the liquid rubber 14 is high, the hard plate 15 is disposed in advance to prevent the liquid rubber 14 from flowing out. Then, after the liquid rubber 14 is cured, the hard plate 15 is removed to complete the seal structure.

また、伸縮性部材６としては、ゴム状シートを採用することもできる。ゴム状シートを施工する場合は、まず、接着剤を貫通孔２の内周面２ａおよび配管３の外周面３ａに塗布する。次いで、ゴム状シートを配管３と貫通孔２の内周面２ａとの間に装着し、ゴム状シートと配管３、およびゴム状シートと貫通孔２の内周面２ａとを接着させる。そして、接着剤を硬化させることによりシール構造が完成する。   Moreover, as the elastic member 6, a rubber-like sheet | seat can also be employ | adopted. When constructing the rubber sheet, first, an adhesive is applied to the inner peripheral surface 2 a of the through hole 2 and the outer peripheral surface 3 a of the pipe 3. Next, the rubber sheet is attached between the pipe 3 and the inner peripheral surface 2 a of the through hole 2, and the rubber sheet and the pipe 3 and the rubber sheet and the inner peripheral surface 2 a of the through hole 2 are bonded. Then, the seal structure is completed by curing the adhesive.

また、既設のシール構造に本実施形態の伸縮性部材６を適用する場合において、既設の充填シール材５が十分な軸方向の厚さを有していない場合においては、追加の充填シール材５を施工した後、伸縮性部材６を施工することができる。即ち、既設のシール構造にも容易に適用することができる。   Further, when the stretchable member 6 of the present embodiment is applied to an existing seal structure, when the existing filling seal material 5 does not have a sufficient axial thickness, the additional filling seal material 5 is used. After the construction, the stretchable member 6 can be constructed. That is, it can be easily applied to an existing seal structure.

（第二実施形態）
次に、第二実施形態に係るシール構造について説明する。
図１１に示すように、本実施形態における充填シール材５Ａの屋外側を向く面は、径方向内側に第一傾斜面５Ａａと、その外側に接続される第二傾斜面５Ａｂとを備えている。第一傾斜面５Ａａは、縦断面視において、径方向外側に向かうにしたがって屋外側から屋内側に向かって断面が直線状に延びており、換言すれば、壁部１の屋外側である第二の面１ｂから壁部１の厚さ方向（配管３の軸方向）における中央部を向く方向（厚さ方向の一方側）に直線状に延びる環状の円錐台状をなしている。
一方、第二傾斜面５Ａｂは、縦断面視において、径方向外側に向かうにしたがって屋内側から屋外側に向かって断面が直線状に延びており、換言すれば、壁部１の厚さ方向（配管３の軸方向）における中央部から壁部１の屋外側である第二の面１ｂを向く方向（厚さ方向の他方側）に直線状に延びる環状の円錐台面である。即ち、第一傾斜面５Ａａと第二傾斜面５Ａｂとでは、径方向外側に向かうにしたがって延びる方向が互いに反対となっている。したがって、第一傾斜面５Ａａの外側に第二傾斜面５ｂの内側が接続されることにより、充填シール材５Ａの屋外側を向く面の径方向中間部（第一傾斜面５Ａａと第二傾斜面５Ａｂの接続部）が屋外側から屋内側に向けて窪んだ凹面状となっている。 (Second embodiment)
Next, the seal structure according to the second embodiment will be described.
As shown in FIG. 11, the surface facing the outdoor side of the filling sealing material 5A in this embodiment includes a first inclined surface 5Aa on the radially inner side and a second inclined surface 5Ab connected to the outer side. . The first inclined surface 5Aa has a cross section that extends linearly from the outdoor side toward the indoor side in the longitudinal cross-sectional view as it goes radially outward. It forms the shape of a circular truncated cone extending linearly in the direction (one side in the thickness direction) from the surface 1b toward the center in the thickness direction of the wall 1 (the axial direction of the pipe 3).
On the other hand, the second inclined surface 5Ab has a linearly extending cross section from the indoor side to the outdoor side as it goes radially outward in the longitudinal sectional view, in other words, in the thickness direction of the wall portion 1 ( It is an annular truncated conical surface that extends linearly from the central portion (in the axial direction of the pipe 3) toward the second surface 1b that is the outdoor side of the wall portion 1 (the other side in the thickness direction). That is, in the first inclined surface 5Aa and the second inclined surface 5Ab, the directions extending toward the radially outer side are opposite to each other. Therefore, by connecting the inside of the second inclined surface 5b to the outside of the first inclined surface 5Aa, the radial intermediate portion of the surface facing the outdoor side of the filling sealing material 5A (the first inclined surface 5Aa and the second inclined surface) 5Ab connecting portion) has a concave shape recessed from the outdoor side toward the indoor side.

伸縮性部材６Ａは、充填シール材５Ａの屋外側を向く凹面全体にわたってほぼ一定の厚さで積層された第一傾斜部６Ａａおよび第二傾斜部６Ａｂからなる。したがって、第一傾斜部６Ａａは、充填シール材５Ａの第一傾斜面５Ａａと同様に、縦断面視において、径方向外側に向かうにしたがって屋外側から屋内側に向かって直線状に延びており、換言すれば、充填シール材５Ａ側に向かって直線状に延びる環状の円錐台状をなしている。
また、第二傾斜部６Ａｂは、充填シール材５Ａの第二傾斜面５Ａｂと同様に、縦断面視において、径方向外側に向かうにしたがって屋内側から屋外側に向かって直線状に延びており、換言すれば、充填シール材５Ａとは反対側に向かって直線状に延びる環状の円錐台状をなしている。即ち、第一傾斜部６Ａａと第二傾斜部６Ａｂとでは、径方向外側に向かうにしたがって延びる方向が互いに反対となっている。したがって、第一傾斜部６Ａａの外側に第二傾斜部６Ａｂの内側が接続されることにより、伸縮性部材６Ａの径方向中間部（第一傾斜部６Ａａと第二傾斜部６Ａｂの接続部）が屋外側から屋内側に向けて窪んだ凹形状となっている。 The elastic member 6A is composed of a first inclined portion 6Aa and a second inclined portion 6Ab that are laminated with a substantially constant thickness over the entire concave surface facing the outdoor side of the filling sealing material 5A. Therefore, like the first inclined surface 5Aa of the filling sealing material 5A, the first inclined portion 6Aa extends linearly from the outdoor side toward the indoor side as it goes radially outward in the longitudinal sectional view. In other words, it has an annular truncated cone shape extending linearly toward the filling sealing material 5A side.
Further, the second inclined portion 6Ab extends linearly from the indoor side toward the outdoor side in the longitudinal cross-sectional view, like the second inclined surface 5Ab of the filling sealing material 5A, as it goes radially outward. In other words, it has an annular truncated cone shape that extends linearly toward the opposite side to the filling sealing material 5A. That is, in the first inclined portion 6Aa and the second inclined portion 6Ab, the directions extending toward the radially outer side are opposite to each other. Therefore, by connecting the inner side of the second inclined part 6Ab to the outer side of the first inclined part 6Aa, the radial intermediate part of the elastic member 6A (the connecting part between the first inclined part 6Aa and the second inclined part 6Ab). It has a concave shape that is recessed from the outdoor side toward the indoor side.

本実施形態によれば、図１２の配管３の下方に見られるように、壁部１の貫通孔２と配管３との相対変位により、貫通孔２の内周面２ａと配管３の外周面３ａとが接近して充填シール材５Ａおよび伸縮性部材６Ａが圧縮された場合においても、充填シール材５Ａおよび伸縮性部材６Ａには屋内側に窪んだ凹形状部を設けているので、この凹状に接続された伸縮性部材６Ａの第一傾斜部６Ａａおよび第二傾斜部６Ａｂが、充填シール材５Ａの変形に追従するように曲げ変形しながら屋内側に逃げることができる。これにより、充填シール材５Ａおよび伸縮性部材６Ａが圧縮されても、その相対変位を吸収することができ、伸縮性部材６Ａが座屈されることを回避し易くなる。したがって、シール構造の気密性および水密性を確保することができる。   According to this embodiment, the inner peripheral surface 2a of the through hole 2 and the outer peripheral surface of the pipe 3 are caused by relative displacement between the through hole 2 of the wall 1 and the pipe 3 as seen below the pipe 3 of FIG. Even when the filling sealing material 5A and the stretchable member 6A are compressed by approaching 3a, the filling sealing material 5A and the stretchable member 6A are provided with a recessed portion recessed on the indoor side. The first inclined portion 6Aa and the second inclined portion 6Ab of the stretchable member 6A connected to can escape to the indoor side while bending and deforming so as to follow the deformation of the filling sealing material 5A. Thereby, even if the filling sealing material 5A and the elastic member 6A are compressed, the relative displacement can be absorbed, and the elastic member 6A can be easily prevented from buckling. Therefore, the airtightness and watertightness of the seal structure can be ensured.

また、伸縮性部材６Ａと貫通孔２の内周面２ａとの間、および伸縮性部材６Ａと配管３の外周面３ａとの間にはプライマー７が介在しているため、図１２の配管３の上方に見られるように、伸縮性部材６Ａが引張りの力を受けた場合においても接着性が維持され、伸縮性部材６Ａとの間に隙間が生じることがない。   Further, since the primer 7 is interposed between the elastic member 6A and the inner peripheral surface 2a of the through hole 2 and between the elastic member 6A and the outer peripheral surface 3a of the pipe 3, the pipe 3 in FIG. As can be seen from above, the adhesiveness is maintained even when the stretchable member 6A receives a tensile force, and no gap is formed between the stretchable member 6A and the stretchable member 6A.

なお、第一実施形態と同様に、伸縮性部材６Ａとして液状ゴム１４やゴム状シートを採用することもできる。   As in the first embodiment, liquid rubber 14 or a rubber-like sheet can be used as the elastic member 6A.

（第三実施形態）
次に、第三実施形態に係るシール構造について説明する。
なお、本実施形態では、伸縮性部材、および、充填シール材の伸縮性部材を積層する面の形状が、上述した第一実施形態と相違するのみであるため、その他の同様の部分についてはその説明を省略する。 (Third embodiment)
Next, the seal structure according to the third embodiment will be described.
In addition, in this embodiment, since the shape of the surface which laminates | stretches the elastic member and the elastic member of a filling sealing material is only different from 1st embodiment mentioned above, about other similar parts, Description is omitted.

図１３に示すように、本実施形態における充填シール材５Ｂの屋外側を向く面は、径方向の外側から内側に向けて一組の第一傾斜面５Ｂａおよび第二傾斜面５Ｂｂと、更にもう一組の第一傾斜面５Ｂａおよび第二傾斜面５Ｂｂとを備えている。即ち、第一傾斜面５Ｂａおよび第二傾斜面５Ｂｂが径方向において交互に二つずつ同心円状に設けられている。換言すれば、充填シール材５Ａの屋外側を向く面は、一組の第一傾斜面５Ｂａと第二傾斜面５Ｂｂとからなる屋内側から屋外側へ突出する凸面が二組形成されている。   As shown in FIG. 13, the surface facing the outdoor side of the filling sealing material 5B in the present embodiment is a set of the first inclined surface 5Ba and the second inclined surface 5Bb from the outer side to the inner side in the radial direction. A pair of first inclined surface 5Ba and second inclined surface 5Bb are provided. That is, the first inclined surface 5Ba and the second inclined surface 5Bb are provided concentrically in pairs in the radial direction. In other words, on the surface facing the outdoor side of the filling sealing material 5A, two sets of convex surfaces are formed that protrude from the indoor side to the outdoor side consisting of a pair of first inclined surface 5Ba and second inclined surface 5Bb.

伸縮性部材６Ｂも同様に、径方向の外側から内側に向けて一組の第一傾斜部６Ｂａおよび第二傾斜部６Ｂｂと、更にもう一組の第一傾斜部６Ｂａおよび第二傾斜部６Ｂｂとを備えている。即ち、第一傾斜部６Ｂａおよび第二傾斜部６Ｂｂが径方向において交互に二つずつ同心円状に設けられている。換言すれば、伸縮性部材６Ｂは、一組の第一傾斜部６Ｂａと第二傾斜部６Ｂｂとからなる屋内側から屋外側へ突出する凸形状部が二組形成されている。   Similarly, the elastic member 6B has a pair of first inclined portion 6Ba and second inclined portion 6Bb from the radially outer side toward the inner side, and another set of first inclined portion 6Ba and second inclined portion 6Bb. It has. That is, the first inclined portion 6Ba and the second inclined portion 6Bb are provided concentrically in pairs in the radial direction. In other words, the elastic member 6B is formed with two sets of convex-shaped portions that protrude from the indoor side to the outdoor side, which are composed of a pair of the first inclined portion 6Ba and the second inclined portion 6Bb.

本実施形態によれば、壁部１の貫通孔２と配管３との相対変位により、貫通孔２の内周面２ａと配管３の外周面３ａとが接近して充填シール材５Ｂおよび伸縮性部材６Ｂが圧縮された場合においても、伸縮性部材６Ｂに第一傾斜部６Ｂａおよび第二傾斜部６Ｂｂを交互に複数設けることで、伸縮性部材６Ｂの曲げ変形、および、それによる相対変位の吸収を径方向における複数箇所に分散させることができる。したがって、伸縮性部材６Ｂの座屈をより回避し易くなるので、シール構造の気密性および水密性を更に向上させることができる。   According to the present embodiment, due to the relative displacement between the through hole 2 and the pipe 3 in the wall portion 1, the inner peripheral surface 2 a of the through hole 2 and the outer peripheral surface 3 a of the pipe 3 approach each other, and the filling sealing material 5 </ b> B and the stretchability are obtained. Even when the member 6B is compressed, the elastic member 6B is provided with a plurality of the first inclined portions 6Ba and the second inclined portions 6Bb alternately, thereby bending the elastic member 6B and absorbing the relative displacement caused thereby. Can be dispersed in a plurality of locations in the radial direction. Therefore, since it becomes easier to avoid buckling of the elastic member 6B, the airtightness and watertightness of the seal structure can be further improved.

なお、本実施形態では凸形状部を二組としたが、これに限らず、三組以上としてもよい。また、伸縮性部材６Ｂが第一傾斜部６Ｂａおよび第二傾斜部６Ｂｂの少なくとも一方を複数有し、かつ第一傾斜部６Ｂａおよび第二傾斜部６Ｂｂが径方向において交互に接続されていればよく、例えば、径方向の外側から内側に向けて第一傾斜部６Ｂａ、第二傾斜部６Ｂｂ、第一傾斜部６Ｂａという３つの傾斜部の組合せなどでも構わない。   In this embodiment, two sets of convex portions are used. However, the present invention is not limited to this, and three or more sets may be used. Moreover, the elastic member 6B should just have at least one of 1st inclination part 6Ba and 2nd inclination part 6Bb, and 1st inclination part 6Ba and 2nd inclination part 6Bb should be alternately connected in radial direction. For example, a combination of three inclined portions such as the first inclined portion 6Ba, the second inclined portion 6Bb, and the first inclined portion 6Ba from the outer side to the inner side in the radial direction may be used.

なお、本発明の技術範囲は上記の実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲において、種々の変更や組合せを加えることが可能である。例えば、以上で説明した各実施形態では、貫通孔２を挿通する配設部材として配管３を用いたが、これに限ることはなく、ダクトや電線など建屋の内外に延在するあらゆる配設部材に対して本発明を適用することができる。   The technical scope of the present invention is not limited to the above embodiment, and various modifications and combinations can be added without departing from the spirit of the present invention.
