Description

本発明は、雨仕舞構造に関する。 The present invention relates to a rain-fighting structure.

建屋の外壁に配管を通すための開口を形成する際、開口を囲む環状部に断面Ｌ字状の開口補強部材（コーナーアングル）を設ける場合がある（特許文献１参照）。この場合、外壁と開口補強部材の隙間をコーキング材によって塞ぐとともに、開口補強部材と配管との間をシールプレートで覆い、当該シールプレートを開口補強部材に溶接すれば、開口から雨水が屋内に浸入するのを防ぐ雨仕舞を行うことができる。 When forming an opening for passing a pipe through the outer wall of a building, an opening reinforcing member (corner angle) having an L-shaped cross section may be provided in an annular portion surrounding the opening (see Patent Document 1). In this case, if the gap between the outer wall and the opening reinforcing member is closed with a caulking material, the space between the opening reinforcing member and the pipe is covered with a seal plate, and the seal plate is welded to the opening reinforcing member, rainwater can enter the room through the opening. You can do a rain-fighting to prevent it from happening.

ところで、シールプレートを開口補強部材に溶接すると、溶接の熱によって開口補強部材が変形し、外壁と開口補強部材との間の隙間が広がるおそれがある。そのため、外壁と開口補強部材の隙間を塞ぐコーキング作業は、溶接作業の後に行うことになる。 By the way, when the seal plate is welded to the opening reinforcing member, the opening reinforcing member may be deformed by the heat of welding, and the gap between the outer wall and the opening reinforcing member may widen. Therefore, the caulking work for closing the gap between the outer wall and the opening reinforcing member is performed after the welding work.

ここで、建屋を施工する建築チームと配管を施工する配管チームが分かれている場合、上述したコーキング作業は建築チームによって行われ、溶接作業は配管チームによって行われる。そうすると、建屋が完成して建築チームから配管チームへ引き渡しが行われたにもかかわらず、配管チームによって配管の施工及び雨仕舞における上記の溶接作業が行われた後、さらに配管チームから建築チームへ引き渡しが行われてコーキング作業が行われることになる。このように従来の雨仕舞の作業では、引き渡しが何度も行われるため非効率であった。 Here, when the building team that constructs the building and the piping team that constructs the piping are separated, the above-mentioned caulking work is performed by the construction team, and the welding work is performed by the piping team. Then, even though the building was completed and handed over from the construction team to the plumbing team, after the plumbing team performed the above welding work in the construction of the plumbing and the rain, the plumbing team further moved to the construction team. Delivery will be carried out and coking work will be carried out. In this way, the conventional rain-fighting work is inefficient because the delivery is performed many times.

本発明は、このような事情に鑑みてなされたものであって、溶接作業の前にコーキング作業を行うことが可能な雨仕舞構造を提供することを目的とする。 The present invention has been made in view of such circumstances, and an object of the present invention is to provide a rain-sealing structure capable of performing a caulking operation before a welding operation.

本発明の一態様に係る雨仕舞構造は、配管が通る外壁の開口から屋内に雨水が侵入するのを防ぐ雨仕舞構造であって、前記開口を囲む前記外壁の環状部に沿って設けられた開口補強部材と、前記外壁と前記開口補強部の隙間を塞ぐコーキング材で形成されたコーキング部と、前記開口補強部材と前記配管との間を覆うシールプレートと、を備え、前記開口補強部材は、前記環状部の内周面側に位置する内周部と、前記環状部の屋外面側に位置する外面部と、前記外面部から前記開口の中心に向かって延びる延長部と、を有し、前記シールプレートの外縁が前記開口補強部材の延長部に溶接接合されている。 The rain-sealing structure according to one aspect of the present invention is a rain-sealing structure that prevents rainwater from entering the room through an opening of an outer wall through which a pipe passes, and is provided along an annular portion of the outer wall surrounding the opening. The opening reinforcing member includes a caulking portion formed of a caulking material that closes a gap between the outer wall and the opening reinforcing portion, and a seal plate that covers between the opening reinforcing member and the piping. It has an inner peripheral portion located on the inner peripheral surface side of the annular portion, an outer surface portion located on the outdoor surface side of the annular portion, and an extension portion extending from the outer surface portion toward the center of the opening. , The outer edge of the seal plate is welded to the extension of the opening reinforcing member.

この構成によれば、開口補強部材のうち開口側に位置する延長部にシールプレートが溶接されるため、外壁側に位置する外面部には溶接の熱が伝わりにくい。そのため、溶接作業を行っても外壁と外面部の隙間、すなわち外壁と開口補強部材の隙間が広がりにくいため、溶接作業の前にコーキング作業を行うことができる。 According to this configuration, since the seal plate is welded to the extension portion of the opening reinforcing member located on the opening side, the heat of welding is not easily transferred to the outer surface portion located on the outer wall side. Therefore, even if the welding work is performed, the gap between the outer wall and the outer surface portion, that is, the gap between the outer wall and the opening reinforcing member is unlikely to widen, so that the caulking work can be performed before the welding work.

上記の雨仕舞構造において、前記外壁はコンクリート壁であって、前記開口補強部材は前記外壁に埋め込まれていてもよい。 In the above rain-fighting structure, the outer wall may be a concrete wall, and the opening reinforcing member may be embedded in the outer wall.

外壁がコンクリート壁の場合、外壁を成形する際に開口補強部材を埋め込むことにより、開口補強部材を外壁にしっかりと固定することができる。 When the outer wall is a concrete wall, the opening reinforcing member can be firmly fixed to the outer wall by embedding the opening reinforcing member when molding the outer wall.

上記の雨仕舞構造において、前記外壁はＡＬＣ壁であって、前記開口補強部材は前記外壁にボルト接合されていてもよい。 In the rain closing structure, the outer wall may be an ALC wall, and the opening reinforcing member may be bolted to the outer wall.

外壁がＡＬＣ壁の場合、外壁を成形する際に開口補強部材を埋め込むことができないが、ボルト結合により開口補強部材を外壁にしっかりと固定することができる。 When the outer wall is an ALC wall, the opening reinforcing member cannot be embedded when molding the outer wall, but the opening reinforcing member can be firmly fixed to the outer wall by bolt connection.

前述したとおり、上記の雨仕舞構造によれば、溶接作業の前にコーキング作業を行うことができる。 As described above, according to the above-mentioned rain-sealing structure, the caulking operation can be performed before the welding operation.

Further, FIG. 3 is a view of the rain closing structure 100 viewed from the outside, and FIG. 4 is a view of the rain closing structure 100 viewed from the inside.

本実施形態に係る雨仕舞構造１００は建屋の外壁１０１の雨仕舞を行うための構造である。具体的には、外壁１０１には配管１０２を通すための開口１０３が形成されており、雨仕舞構造１００はこの開口１０３から雨水が侵入するのを防いでいる。 The rain closing structure 100 according to the present embodiment is a structure for performing rain closing of the outer wall 101 of the building. Specifically, an opening 103 for passing the pipe 102 is formed in the outer wall 101, and the rain closing structure 100 prevents rainwater from entering through the opening 103.

本実施形態の外壁１０１はコンクリートで形成されたコンクリート壁である。外壁１０１には正面から見て正方形の開口１０３が形成されている。ただし、開口１０３の形状は正方形以外の形状であってもよい。開口１０３の中心部分には配管１０２が貫通しており、配管１０２は外壁１０１に対して垂直の方向に延びている。また、配管１０２の外周面には保温材１０４が取り付けられている。保温材１０は特に限定されず、例えばウレタンフォームやグラスウールなどを用いることができる。なお、以下では、外壁１０１の開口１０３を囲む環状（矩形枠状）の部分を「環状部１０５」と呼ぶこととする。 The outer wall 101 of the present embodiment is a concrete wall made of concrete. The outer wall 101 is formed with a square opening 103 when viewed from the front. However, the shape of the opening 103 may be a shape other than a square. A pipe 102 penetrates through the central portion of the opening 103, and the pipe 102 extends in a direction perpendicular to the outer wall 101. Further, a heat insulating material 104 is attached to the outer peripheral surface of the pipe 102. The heat insulating material 10 is not particularly limited, and for example, urethane foam, glass wool, or the like can be used. In the following, the annular (rectangular frame-shaped) portion surrounding the opening 103 of the outer wall 101 will be referred to as the “annular portion 105”.

図１に示すように、本実施形態に係る雨仕舞構造１００は、外壁１０１に設けられた開口補強部材１０と、開口補強部材１０の外縁に位置するコーキング部２０と、開口１０３を屋外側から塞ぐシールプレート３０と、開口１０３を屋内側から塞ぐ目隠しプレート４０と、を備えている。以下、これらの各構成要素について順に説明する。 As shown in FIG. 1, in the rain closing structure 100 according to the present embodiment, the opening reinforcing member 10 provided on the outer wall 101, the caulking portion 20 located at the outer edge of the opening reinforcing member 10, and the opening 103 are provided from the outdoor side.

Since the outer wall 101 of the present embodiment is a concrete wall, the outer wall 101 is molded using a formwork at the construction site. Therefore, the first opening reinforcing member 11 can be embedded in the outer wall 101 when the outer wall 101 is formed. Further, as shown in FIG. 3, the first opening reinforcing member 11 has a rectangular frame shape when viewed from the outside.

図２に示すように、第１開口補強部材１１は、断面Ｔ字状に形成されており、環状部１０５の内周面側に位置する内周部１３と、環状部１０５の屋外面側に位置する外面部１４と、外面部１４から開口１０３の中心に向かって延びる延長部１５とを有している。また、延長部１５は、内周部１３及び外面部１４よりも開口１０３の中心近くに位置している。なお、内周部１３及び外面部１４が外壁１０１に接しているのに対し、延長部１５は外壁１０１に接していない。 As shown in FIG. 2, the first opening reinforcing member 11 is formed in a T-shaped cross section, and is located on the inner peripheral surface side of the annular portion 105 and on the outdoor surface side of the annular portion 105.

＜施工手順＞
続いて、本実施形態に係る雨仕舞構造１００の施工手順について説明する。本実施形態では、雨仕舞構造１００の施工は、建屋を施工する建築チームと配管を施工する配管チームによって行われる。まず、建築チームによって、開口１０３が形成されるように型枠を用いて外壁１０１を成形する。この成形の際、開口１０３を囲む環状部１０５に開口補強部材１０を埋め込む。 <Construction procedure>
Subsequently, the construction procedure of the rain-retaining structure 100 according to the present embodiment will be described. In the present embodiment, the construction of the rain-fighting structure 100 is performed by the construction team that constructs the building and the piping team that constructs the piping. First, the building team molds the outer wall 101 using the formwork so that the opening 103 is formed. At the time of this molding, the opening reinforcing member 10 is embedded in the annular portion 105 surrounding the opening 103.

続いて、建築チームによって、開口補強部材１０における第１開口補強部材１１の外縁と外壁１０１の隙間をコーキング材で塞いでコーキング部２０を形成する。その後、建築チームから配管チームへ引き渡しが行われ、以降の作業は配管チームによって行われる。 Subsequently, the building team closes the gap between the outer edge of the first opening reinforcing member 11 and the outer wall 101 of the opening reinforcing member 10 with a caulking material to form the caulking portion 20. After that, it is handed over from the construction team to the plumbing team, and the subsequent work is done by the plumbing team.

配管チームは、外壁１０１の開口１０３に配管１０２を通し、第１開口補強部材１１と配管１０２との間を覆うようにしてシールプレート３０を取り付ける。この取付は、シールプレート３０の外縁を第１開口補強部材１１の延長部１５に溶接することによって行う。 The piping team passes the piping 102 through the opening 103 of the outer wall 101, and attaches the seal plate 30 so as to cover between the first opening reinforcing member 11 and the piping 102. This attachment is performed by welding the outer edge of the seal plate 30 to the extension portion 15 of the first opening reinforcing member 11.

ここで、シールプレート３０を第１開口補強部材１１に溶接すると、溶接の熱が第１開口補強部材１１に伝わり、第１開口補強部材１１が変形するおそれがある。ただし、本実施形態では、シールプレート３０は第１開口補強部材１１の外面部１４ではなく外面部１４よりも開口１０３の中心に近い延長部１５に溶接されるため、溶接の熱は外面部１４に伝わりにくい。そのため、外面部１４については、溶接の熱による変形は生じにくく、外面部１４と外壁１０１の隙間は拡大しにくい。よって、上記のコーキング作業を行った後に溶接作業を行っても、開口補強部材１０と外壁１０１の隙間は広がりにくいため、コーキング作業をやり直す必要はない。 Here, when the seal plate 30 is welded to the first opening reinforcing member 11, the heat of welding is transferred to the first opening reinforcing member 11, and the first opening reinforcing member 11 may be deformed. However, in the present embodiment, since the seal plate 30 is welded not to the outer surface portion 14 of the first opening reinforcing member 11 but to the extension portion 15 closer to the center of the opening 103 than the outer surface portion 14, the heat of welding is applied to the outer surface portion 14. It is difficult to convey to. Therefore, the outer surface portion 14 is less likely to be deformed by the heat of welding, and the gap between the outer surface portion 14 and the outer wall 101 is less likely to expand. Therefore, even if the welding work is performed after the above caulking work, the gap between the opening reinforcing member 10 and the outer wall 101 is unlikely to widen, so that it is not necessary to redo the caulking work.

続いて、配管１０２に保温材１０４を取り付けるとともに保温材１０４を保護するラッキング処理を行い、その後、保温材１０４と外壁１０１の環状部１０５との間に充填材４３を充填する。そしてさらに、充填した充填材４３に蓋をするようにして、目隠しプレート４０を第２開口補強部材１２の屋内側の部分に取り付ける。この取付は目隠しプレート４０を第２開口補強部材１２の外面部１７に溶接することによって行う。なお、この溶接は、シール溶接である必要はなく、スポット溶接等であってもよい。 Subsequently, the heat insulating material 104 is attached to the pipe 102 and a racking process is performed to protect the heat insulating material 104, and then the filler 43 is filled between the heat insulating material 104 and the annular portion 105 of the outer wall 101. Further, the blind plate 40 is attached to the indoor side portion of the second opening reinforcing member 12 so as to cover the filled filler 43. This attachment is performed by welding the blind plate 40 to the outer surface portion 17 of the second opening reinforcing member 12. It should be noted that this welding does not have to be seal welding, and may be spot welding or the like.

ここで、目隠しプレート４０を第２開口補強部材１２の外面部１７に溶接すると、溶接の熱によって第２開口補強部材１２は変形し、第２開口補強部材１２と外壁１０１との隙間が拡大するおそれがある。しかしながら、通常は、第２開口補強部材１２と外壁１０１の隙間を雨水が通って屋内に流入することはないため、第２開口補強部材１２と外壁１０１との隙間が拡大したとしても、第２開口補強部材１２が外壁１０１に固定されていれば特に問題はない。 Here, when the blind plate 40 is welded to the outer surface portion 17 of the second opening reinforcing member 12, the second opening reinforcing member 12 is deformed by the heat of welding, and the gap between the second opening reinforcing member 12 and the outer wall 101 is expanded. There is a risk. However, normally, rainwater does not pass through the gap between the second opening reinforcing member 12 and the outer wall 101 and flow into the room. Therefore, even if the gap between the second opening reinforcing member 12 and the outer wall 101 is expanded, the second opening reinforcing member 12 and the outer wall 101 are second. If the opening reinforcing member 12 is fixed to the outer wall 101, there is no particular problem.

以上が、本実施形態に係る雨仕舞構造１００の施工手順である。上記のとおり、本実施形態によれば、シールプレート３０を第１開口補強部材１１に溶接しても、外面部１４と外壁１０１の隙間は拡大しにくいため、溶接作業の前にコーキング作業を行うことが可能となる。よって、建築チームが配管チームに引き渡しを行った後に、再び配管チームから建築チームに引き渡しを行う必要がない。その結果、雨仕舞の作業を効率よく行うことができる。 The above is the construction procedure of the rain cover structure 100 according to the present embodiment. As described above, according to the present embodiment, even if the seal plate 30 is welded to the first opening reinforcing member 11, the gap between the outer surface portion 14 and the outer wall 101 is unlikely to expand, so that the caulking work is performed before the welding work. It becomes possible. Therefore, it is not necessary to hand over from the piping team to the building team again after the building team hands over to the piping team. As a result, the work of closing the rain can be performed efficiently.

（第２実施形態）
次に、本発明の第２実施形態に係る雨仕舞構造２００について説明する。第２実施形態では、第１実施形態の構成要素と同じ又は対応する構成要素には同じ符号を付して、重複する説明は省略する。図５は、第２実施形態に係る雨仕舞構造２００の縦断面図である。 (Second Embodiment)
Next, the rain closing structure 200 according to the second embodiment of the present invention will be described. In the second embodiment, the same or corresponding components as the components of the first embodiment are designated by the same reference numerals, and duplicate description will be omitted. FIG. 5 is a vertical cross-sectional view of the rain storage structure 200 according to the second embodiment.

第２実施形態は、外壁１０１がＡＬＣ（Autoclaved Lightweight aerated Concrete；軽量気泡コンクリート）壁である点で、外壁１０１がコンクリート壁である第１実施形態と異なる。ＡＬＣ壁は、内部に鉄筋が無いことから通常はコンクリート壁よりも薄い。また、ＡＬＣ壁は、予め工場で製造されて施工現場に運び込まれるプレキャスト製品である。そのため、第２実施形態では、開口補強部材１０は外壁１０１に埋め込まれておらず、ボルト接合により外壁１０１に固定されている。具体的には、図５で示すように、第２開口補強部材１２がボルト５１によって外壁１０１に固定されており、第１開口補強部材１１が第２開口補強部材１２に溶接接合されている。なお、開口補強部材１０を外壁１０１に固定する作業は建築チームによって行われ、その後、同じく建築チームによってコーキング作業が行われる。 The second embodiment is different from the first embodiment in that the outer wall 101 is an ALC (Autoclaved Lightweight aerated Concrete) wall, and the outer wall 101 is a concrete wall. ALC walls are usually thinner than concrete walls because there are no reinforcing bars inside. The ALC wall is a precast product that is manufactured in advance at the factory and brought to the construction site. Therefore, in the second embodiment, the opening reinforcing member 10 is not embedded in the outer wall 101, but is fixed to the outer wall 101 by bolt joining. Specifically, as shown in FIG. 5, the second opening reinforcing member 12 is fixed to the outer wall 101 by the bolt 51, and the first opening reinforcing member 11 is welded to the second opening reinforcing member 12. The work of fixing the opening reinforcing member 10 to the outer wall 101 is performed by the construction team, and then the caulking work is also performed by the construction team.

また、第２実施形態では、第１実施形態と同様に開口補強部材１０は第１開口補強部材１１と第２開口補強部材１２によって構成されている。ただし、第１開口補強部材１１と第２開口補強部材１２とは互いに接合されている。具体的には、図５に示すように、第１開口補強部材１１の内周部１３は第２開口補強部材１２の内周部１６よりも配管１０２寄りに位置しており、この状態で第１開口補強部材１１と第２開口補強部材１２とが溶接接合されている。 Further, in the second embodiment, the opening reinforcing member 10 is composed of the first opening reinforcing member 11 and the second opening reinforcing member 12 as in the first embodiment. However, the first opening reinforcing member 11 and the second opening reinforcing member 12 are joined to each other. Specifically, as shown in FIG. 5, the inner peripheral portion 13 of the first opening reinforcing member 11 is located closer to the pipe 102 than the inner peripheral portion 16 of the second opening reinforcing member 12, and in this state, the first The 1 opening reinforcing member 11 and the 2nd opening reinforcing member 12 are welded together.

第２実施形態に係る雨仕舞構造２００は第１実施形態に係る雨仕舞構造１００と上記のような違いがあるが、シールプレート３０が第１開口補強部材１１の延長部１５に溶接接合されている点は、第１実施形態に係る雨仕舞構造１００と同じである。よって、本実施形態に係る雨仕舞構造２００であっても、シールプレート３０を開口補強部材１０に溶接したときに開口補強部材１０と外壁１０１の隙間は拡大しにくい。そのため、溶接作業の前にコーキング作業を行うことが可能となり、ひいては雨仕舞の作業を効率よく行うことができる。 The rain-sealing structure 200 according to the second embodiment is different from the rain-sealing structure 100 according to the first embodiment as described above, but the seal plate 30 is welded to the extension portion 15 of the first opening reinforcing member 11. The point is the same as the rain closing structure 100 according to the first embodiment. Therefore, even in the rain closing structure 200 according to the present embodiment, the gap between the opening reinforcing member 10 and the outer wall 101 is unlikely to expand when the seal plate 30 is welded to the opening reinforcing member 10. Therefore, it is possible to perform caulking work before welding work, and by extension, it is possible to efficiently perform rain-fighting work.
