Description

【発明の属する技術分野】
本発明は、建築物の外壁パネル間の目地に嵌入された１次止水用のガスケットに加えて設けられ、目地と目地に対向する鉄骨間の隙間をシールする外壁パネル間の目地用２次止水材の取付構造に関する。
【０００２】
【従来の技術】
図６及び図７に示すように、建築物１には複数の外壁パネル２が貼られており、その外壁パネル２，２間に発生する目地３には１次止水用のガスケット４が圧入され、更に外壁パネル２の内面２ａと、外壁パネル２の内側に設けられた鉄骨５との間には２次止水用のシール材６が挿入されている。
【０００３】
ガスケット４は、ＥＰＤＭソリッドゴム製あるいはＥＰＤＭスポンジゴム製の本体の側面にシールリップ部４ａが形成され、更に本体の表面には装飾用のカラーゴム４ｂが形成された押出成品である。
一方、２次止水用のシール材６は、ＥＰＤＭ連泡スポンジ製であり、目地３と目地３に対向する鉄骨５，５間の隙間５ａをシールするようになっている。
【０００４】
【発明が解決しようとする課題】
しかしながら、２次止水用のシール材６は、位置ずれしないように両面テープ７で鉄骨５に貼着されているため、貼着の際に離型紙がゴミとして発生してしまう。
また、シール材６を両面テープ７によって一度取り付けてしまうと脱着が煩雑であり、特に鉄骨５，５間の隙間５ａのほぼ中央にシール材６の中央をもってくることができればよいが、互いの中央位置がずれてシール材６を取り付けた場合にはシール材６の位置を修正するのに手間がかかるという問題がある。
【０００５】
そこで本発明の目的は、取り付けに両面テープを必要とせず、しかも脱着および位置決めが容易な外壁パネル間の目地用２次止水材の取付構造を提供することにある。
【０００６】
また他の目的は、外壁パネル間の目地用２次止水材の位置ずれを防止することにある。
【０００７】
【課題を解決するための手段】
上記の目的を達成するために、本発明の外壁パネル間の目地用２次止水材の取付構造は、建築物の外壁パネル間の目地に１次止水用のガスケットが圧入されたその外壁パネルの内面と、外壁パネルの内側に設けられた鉄骨との間に挿入され、目地と目地に対向する鉄骨間の隙間をシールするシール部からなる外壁パネル間の目地用２次止水材の取付構造において、前記鉄骨間の隙間に圧入される脚部又は突部を前記シール部に一体成形するもので、前記シール部はＥＰＤＭスポンジゴム製であり、かつ脚部又は突部はＥＰＤＭソリッドゴム製であることを特徴とするものである（請求項１）。
【０００８】
また本発明の外壁パネル間の目地用２次止水材の取付構造は、建築物の外壁パネル間の目地に１次止水用のガスケットが圧入されたその外壁パネルの内面と、外壁パネルの内側に設けられた鉄骨との間に挿入され、目地と目地に対向する鉄骨間の隙間をシールするシール部からなる外壁パネル間の目地用２次止水材の取付構造において、前記鉄骨間の隙間に挿入されるストッパ機能を有する脚部又は突部を前記シール部に一体成形するもので、前記シール部はＥＰＤＭスポンジゴム製であり、かつ脚部又は突部はＥＰＤＭソリッドゴム製であることを特徴とするものである（請求項２）。
【０００９】
更に、本発明の外壁パネル間の目地用２次止水材の取付構造は、建築物の外壁パネル間の目地に１次止水用のガスケットが圧入されたその外壁パネルの内面と、外壁パネルの内側に設けられた鉄骨との間に挿入され、目地と目地に対向する鉄骨間の隙間をシールするシール部からなる外壁パネル間の目地用２次止水材の取付構造において、前記鉄骨間の隙間に圧入される脚部又は突部を前記シール部に一体成形するもので、前記シール部及び脚部又は突部はＥＰＤＭソリッドゴム製であり、シール部の両端部の外壁パネル側の面にＥＰＤＭスポンジゴム製の部材を一体成形したことを特徴とするものである（請求項３）。
【００１０】
また、本発明の外壁パネル間の目地用２次止水材の取付構造は、建築物の外壁パネル間の目地に１次止水用のガスケットが圧入されたその外壁パネルの内面と、外壁パネルの内側に設けられた鉄骨との間に挿入され、目地と目地に対向する鉄骨間の隙間をシールするシール部からなる外壁パネル間の目地用２次止水材の取付構造において、前記鉄骨間の隙間に挿入されるストッパ機能を有する脚部又は突部を前記シール部に一体成形するもので、前記シール部及び脚部又は突部はＥＰＤＭソリッドゴム製であり、シール部の両端部の外壁パネル側の面にＥＰＤＭスポンジゴム製の部材を一体成形したことを特徴とするものである（請求項４）。
【００１１】
また、請求項１乃至請求項４のうちいずれか一つに記載のシール部を水膨張性ゴム製としてもよい（請求項５）。
【００１２】
更に、請求項１乃至請求項５のうちいずれか一つに記載のシール部の外壁パネル側の面に位置ずれ防止用の凸部を一体成形してもよい（請求項６）。
【００１３】
請求項１に記載の発明によれば、シール部には鉄骨間の隙間に圧入される脚部又は突部が一体成形されているので、脚部又は突部の圧入により外壁パネル間の目地用２次止水材は固定され、簡易に位置ずれが防止される。また、特に両面テープなどを使用して目地用２次止水材を鉄骨に直接貼着するものではないので、脱着が容易であり、その上、離型紙などのゴミが発生することもない。更に、脚部又は突部をシール部の中央にくるように一体成形すれば、鉄骨間の隙間に圧入するだけで目地用２次止水材の中央が隙間の中央にくるので位置決めに労力を費やす必要はない。なお、シール部に対する脚部又は突部の取り付け位置は、中央部とは限らず目地の位置と鉄骨間の隙間との位置関係に応じて変化させることができる。
また係止部が鉄骨間の隙間に圧入されることにより鉄骨間が結合して安定化が図れるので、鉄骨を地面に水平に置いてその上から目地用２次止水材を取り付け、更に外壁パネルを鉄骨に例えばボルト締めして取り付けた後に全体を垂直に立てるという作業だけでなく、鉄骨を垂直に立てた状態で目地用２次止水材を取り付け、更に外壁パネルを鉄骨にボルト締めして取り付けるという作業をも容易に実施することができる。
また、シール部をＥＰＤＭスポンジゴム製とし、かつ脚部又は突部をＥＰＤＭソリッドゴム製とするので、シール部によるシール機能と、脚部又は突部による固定するための機能とが十分発揮される。
【００１４】
また請求項２に記載の発明によれば、シール部に一体成形されるストッパ機能を有する脚部又は突部は、請求項１に記載の発明と異なり鉄骨間の隙間に圧入されるものではなく、鉄骨間の隙間に挿入されるものである、すなわち脚部又は突部の幅は鉄骨間の隙間に比較して狭くスキ設定されているので特に鉄骨間の隙間に係止する機能を有するものではないが、ストッパ機能は有するので鉄骨に対して目地用２次止水材が位置ずれしても脚部又は突部が鉄骨に当接してそこで位置決めが行われる。
なお取り付けは、鉄骨を地面に水平に置いてその上から目地用２次止水材を取り付け、更に外壁パネルを鉄骨にボルト締めして取り付けた後に全体を垂直に立てることにより行われる。
また、シール部をＥＰＤＭスポンジゴム製とし、かつ脚部又は突部をＥＰＤＭソリッドゴム製とするので、シール部によるシール機能と、脚部又は突部による固定するための機能とが十分発揮される。
【００１５】
更に請求項３に記載の発明によれば、シール部及び脚部又は突部をＥＰＤＭソリッドゴム製とし、シール部の両端部の外壁パネル側の面にＥＰＤＭスポンジゴム製の部材を一体成形とするので、部分的にではあるがシール性が向上する。
【００１６】
また請求項４に記載の発明によれば、シール部及び脚部又は突部をＥＰＤＭソリッドゴム製とし、シール部の両端部の外壁パネル側の面にＥＰＤＭスポンジゴム製の部材を一体成形とするので、部分的にではあるがシール性が向上する。
【００１７】
また請求項５に記載の発明によれば、シール部を水膨張性ゴム製とするのでシール性が一層向上する。
【００１８】
更に請求項６に記載の発明によれば、シール部の外壁パネル側の面に凸部を一体成形するので、脚部又は突部とともに外壁パネル間の目地用２次止水材の位置ずれ防止が一層図れる。
【００１９】
【発明の実施の形態】
本発明の実施の形態について図面を参照して説明する。なお、従来例と同一の部分には同一符号を付し、その説明を省略する。
図１は本発明の実施の形態に係る外壁パネル間の目地用２次止水材１０を示す断面図であり、図２は図１に示す目地用２次止水材１０を取り付けた状態を示す断面図である。なお図２は、本発明の実施の形態に係る図６のＡ−Ａ線拡大断面図に相当するものである。
【００２０】
外壁パネル間の目地用２次止水材１０は、長手方向に延びるシール部１１とそのシール部１１の中央に一体成形された同じく長手方向に延びる脚部（突部）１２からなる押出成形品である。
シール部１１は、建築物１の外壁パネル２，２間の目地３に１次止水用のガスケット４が圧入されたその外壁パネル２の内面２ａと、外壁パネル２の内側に設けられた鉄骨５との間に挿入されており、これにより目地３と目地３に対向する鉄骨５，５間の隙間５ａをシールするようになっている。
一方、脚部（突部）１２は、その先端に係止部１２ａが形成されており、目地３と目地３に対向する鉄骨５，５間の隙間５ａに圧入され係止部１２ａが隙間５ａに係止することにより外壁パネル間の目地用２次止水材１０が固定され、位置ずれが防止されるようになっている。
【００２１】
これによれば、特に両面テープなどを使用することにより目地用２次止水材１０が鉄骨に直接貼着されていないため、脱着が容易であり、その上、離型紙などのゴミが発生することもない。更に、脚部（突部）１２を鉄骨５，５間の隙間５ａに圧入するだけで目地用２次止水材１０の中央が隙間５ａの中央にくるので位置決めに労力を費やす必要はない。
また係止部１２ａが鉄骨５，５間の隙間５ａに圧入されることにより鉄骨５，５間が結合して安定化が図れるので、鉄骨５を地面に水平に置いてその上から目地用２次止水材１０を取り付け、更に外壁パネル２を鉄骨５にボルト締めして取り付けた後に全体を垂直に立てるという作業だけでなく、鉄骨５を垂直に立てた状態で目地用２次止水材１０を取り付け、更に外壁パネル２を鉄骨５にボルト締めして取り付けるという作業をも容易に実施することができる。
【００２２】
なお、シール部１１および脚部（突部）１２は、図３（ａ）に示す目地用２次止水材１５のようにいずれもＥＰＤＭスポンジゴム製，あるいは図３（ｂ）に示す目地用２次止水材１６のようにいずれもＥＰＤＭソリッドゴム製とすることもできるが、図１に示すようにシール部１１はよりシール機能を向上させるためにＥＰＤＭスポンジゴム製であることが好ましく、また脚部（突部）１２はより強固に外壁パネル間の目地用２次止水材１０を固定させるためにＥＰＤＭソリッドゴム製であることが好ましい。
【００２３】
また、図４（ａ）に示す目地用２次止水材２０のように、シール部２１及び脚部２２をＥＰＤＭソリッドゴム製で一体成形し、更にシール部２１の両端部の外壁パネル側の面にＥＰＤＭスポンジゴム製の部材２３を一体成形して、部分的にシール性を向上させるようにしてもよい。
更に、図４（ｂ）に示す目地用２次止水材３０のように、シール部３１を水膨張性ゴム製にしてシール性を一層向上させるようにしてもよい。
また、図４（ｃ）に示す目地用２次止水材４０のように、シール部４１の外壁パネル側の面に凸部４３を一体成形してより一層の位置ずれの防止を図るようにしてもよい。
【００２４】
更に、図５に示す目地用２次止水材５０のように、鉄骨５，５間の隙間５ａに挿入されるストッパ機能を有する脚部（突部）５２をシール部５１に一体成形するようにしてもよい。すなわち、脚部（突部）５２の先端５２ａの幅は鉄骨５，５間の隙間５ａに比較して狭くスキ設定されているので特に鉄骨５，５間の隙間５ａに係止する機能を有するものではないが、ストッパ機能は有するので鉄骨５に対して目地用２次止水材５０が位置ずれしても脚部（突部）５２の先端５２ａが鉄骨５に当接してそこで位置決めが行われる。
なお取り付けは、鉄骨５を地面に水平に置いてその上から目地用２次止水材５０を取り付け、更に外壁パネル２を鉄骨５にボルト締めして取り付けた後に全体を垂直に立てることにより行われる。
【００２５】
また、目地用２次止水材１０と同様にシール部５１および脚部（突部）５２は、図３（ａ），図３（ｂ）に示すようにいずれもＥＰＤＭスポンジゴム製，あるいはいずれもＥＰＤＭソリッドゴム製とすることもできるが、シール部５１はよりシール機能を向上させるためにＥＰＤＭスポンジゴム製であることが好ましく、また脚部（突部）５２はストッパ機能を強固に果すためにＥＰＤＭソリッドゴム製であることが好ましい。
また、図４（ａ）に示すように、シール部５１及び脚部（突部）５２をＥＰＤＭソリッドゴム製で一体成形し、更にシール部５１の両端部の外壁パネル側の面にＥＰＤＭスポンジゴム製の部材２３を一体成形して、部分的にシール性を向上させるようにしてもよい。更に、図４（ｂ）に示すように、シール部５１を水膨張性ゴム製にしてシール性を一層向上させるようにしてもよい。また、図４（ｃ）に示すように、シール部５１の外壁パネル側の面に凸部４３を一体成形してより一層の位置ずれの防止を図るようにしてもよい。
【００２６】
【発明の効果】
以上のとおり請求項１に記載の発明によれば、シール部には鉄骨間の隙間に圧入される脚部又は突部が一体成形されているので、脚部又は突部の圧入により外壁パネル間の目地用２次止水材は固定され、簡易に位置ずれが防止される。また、特に両面テープなどを使用して目地用２次止水材を鉄骨に直接貼着するものではないので、脱着が容易であり、その上、離型紙などのゴミが発生することもない。更に、脚部又は突部をシール部の中央にくるように一体成形すれば、鉄骨間の隙間に圧入するだけで目地用２次止水材の中央が隙間の中央にくるので位置決めに労力を費やす必要はない。
また係止部が鉄骨間の隙間に圧入されることにより鉄骨間が結合して安定化が図れるので、鉄骨を地面に水平に置いてその上から目地用２次止水材を取り付け、更に外壁パネルを鉄骨に例えばボルト締めして取り付けた後に全体を垂直に立てるという作業だけでなく、鉄骨を垂直に立てた状態で目地用２次止水材を取り付け、更に外壁パネルを鉄骨にボルト締めして取り付けるという作業をも容易に実施することができる。
また、シール部をＥＰＤＭスポンジゴム製とし、かつ脚部又は突部をＥＰＤＭソリッドゴム製とするので、シール部及び脚部又は突部とのいずれをもＥＰＤＭスポンジゴム製あるいはＥＰＤＭソリッドゴム製としたものと比較して、シール部によるシール機能と、脚部又は突部による固定するための機能とが有効に発揮される。
【００２７】
また請求項２に記載の発明によれば、請求項１に記載の発明と同様に両面テープは不要である。またシール部に一体成形される脚部又は突部のストッパ機能により、鉄骨に対して目地用２次止水材が位置ずれしても脚部又は突部が鉄骨に当接したところで位置決めが行われるので、簡易に位置ずれが防止される。
また、シール部をＥＰＤＭスポンジゴム製とし、かつ脚部又は突部をＥＰＤＭソリッドゴム製とするので、シール部及び脚部又は突部とのいずれをもＥＰＤＭスポンジゴム製あるいはＥＰＤＭソリッドゴム製としたものと比較して、シール部によるシール機能と、脚部又は突部による固定するための機能とが有効に発揮される。
【００２８】
更に請求項３，４に記載の発明によれば、シール部及び脚部又は突部をＥＰＤＭソリッドゴム製とし、シール部の両端部の外壁パネル側の面にＥＰＤＭスポンジゴム製の部材を一体成形とするので、部分的にではあるがシール性が向上する。また請求項５に記載の発明によれば、シール部を水膨張性ゴム製とするのでシール性が一層向上する。更に請求項６に記載の発明によれば、シール部の外壁パネル側の面に凸部を一体成形するので、脚部又は突部とともに外壁パネル間の目地用２次止水材の位置ずれ防止が一層図れる。

BACKGROUND OF THE INVENTION
The present invention is provided in addition to a primary water-stopping gasket inserted in a joint between outer wall panels of a building, and is a secondary joint for outer joints between outer wall panels that seals a gap between the joint and the steel frame facing the joint. The present invention relates to a waterproofing material mounting structure .
[0002]
[Prior art]
As shown in FIGS. 6 and 7, a plurality of outer wall panels 2 are stuck on the building 1, and a primary water-stop gasket 4 is press-fitted into the joint 3 generated between the outer wall panels 2 and 2. Further, a sealing material 6 for secondary water stop is inserted between the inner surface 2 a of the outer wall panel 2 and the steel frame 5 provided on the inner side of the outer wall panel 2.
[0003]
The gasket 4 is an extruded product in which a seal lip portion 4a is formed on the side surface of an EPDM solid rubber or EPDM sponge rubber main body, and a decorative color rubber 4b is formed on the surface of the main body.
On the other hand, the sealing material 6 for secondary water stop is made of EPDM foam foam, and seals the gap 5 a between the joint 3 and the steel frames 5, 5 facing the joint 3.
[0004]
[Problems to be solved by the invention]
However, since the sealing material 6 for secondary water stop is stuck to the steel frame 5 with the double-sided tape 7 so as not to be displaced, the release paper is generated as dust at the time of sticking.
In addition, once the sealing material 6 is attached with the double-sided tape 7, it is difficult to detach and attach the center of the sealing material 6 to the approximate center of the gap 5a between the steel frames 5 and 5. When the sealing material 6 is attached with the position shifted, there is a problem that it takes time to correct the position of the sealing material 6.
[0005]
Accordingly, an object of the present invention is to provide a joint structure for a secondary waterstop material for joints between outer wall panels that does not require a double-sided tape for attachment and is easy to be attached and detached and positioned.
[0006]
Another object is to prevent misalignment of the secondary waterstop material for joints between the outer wall panels.
[0007]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the secondary waterproofing material mounting structure between the outer wall panels of the present invention has the outer wall in which a gasket for primary waterproofing is press-fitted into the joint between the outer wall panels of the building. The secondary waterproofing material for joints between the outer wall panels, which is inserted between the inner surface of the panel and the steel frame provided on the inner side of the outer wall panel and seals the gap between the joint and the steel frame facing the joint. In the mounting structure , a leg portion or a projecting portion that is press-fitted into a gap between the steel frames is formed integrally with the seal portion, the seal portion is made of EPDM sponge rubber, and the leg portion or the projecting portion is an EPDM solid rubber. It is characterized by being made (Claim 1).
[0008]
Further, the joint structure of the secondary waterproofing material for joints between the outer wall panels of the present invention includes the inner surface of the outer wall panel in which a gasket for primary waterproofing is press-fitted into the joint between the outer wall panels of the building, and the outer wall panel. In the mounting structure of the secondary waterstop material for joints between the outer wall panels, which is inserted between the steel frames provided on the inner side and seals the gaps between the joints and the steel frames facing the joints . A leg or protrusion having a stopper function to be inserted into the gap is formed integrally with the seal part. The seal part is made of EPDM sponge rubber, and the leg or protrusion is made of EPDM solid rubber. (Claim 2).
[0009]
Furthermore, the mounting structure of the secondary waterproofing material for joints between the outer wall panels of the present invention includes an inner surface of the outer wall panel in which a gasket for primary waterproofing is press-fitted into the joint between the outer wall panels of the building, and the outer wall panel. In the mounting structure of the secondary waterstop material for joints between the outer wall panels, which is inserted between the steel frames provided on the inner side of the steel plate and seals the gaps between the joints and the steel frames facing the joints. Legs or protrusions that are press-fitted into the gaps are formed integrally with the seal part, and the seal part and the leg parts or protrusions are made of EPDM solid rubber, and the outer wall panel side surfaces of both ends of the seal part A member made of EPDM sponge rubber is formed integrally with the above (claim 3).
[0010]
Further, according to the present invention, the joint structure for the secondary waterproofing material for the joint between the outer wall panels includes the inner surface of the outer wall panel in which a gasket for primary waterproofing is press-fitted into the joint between the outer wall panels of the building, and the outer wall panel. is inserted between the inner provided on side steel frame, in the mounting structure of the joint for 2 Tsugitome waterstops between the outer wall panel comprising a seal portion for sealing a gap between the steel facing the joint and joint, the steel A leg or protrusion having a stopper function to be inserted into a gap between the seal part is integrally formed with the seal part. The seal part and the leg part or the protrusion are made of EPDM solid rubber, and are formed at both ends of the seal part. A member made of EPDM sponge rubber is integrally formed on the surface of the outer wall panel (Claim 4).
[0011]
Further, the seal portion according to any one of claims 1 to 4 may be made of water-expandable rubber (claim 5).
[0012]
Furthermore, you may integrally form the convex part for position shift prevention to the surface by the side of the outer wall panel of the seal | sticker part as described in any one of Claims 1 thru | or 5.
[0013]
According to the first aspect of the present invention, since the leg portion or the projecting portion to be press-fitted into the gap between the steel frames is integrally formed in the seal portion, the joint between the outer wall panels can be obtained by the press-fitting of the leg portion or the projecting portion. The secondary water stop material is fixed, and displacement is easily prevented. Moreover, since the secondary water-stopping material for joints is not directly attached to the steel frame using a double-sided tape or the like, it is easy to detach, and no dust such as release paper is generated. Furthermore, if the legs or protrusions are integrally formed so as to be in the center of the seal part, the center of the secondary waterstop material for joints comes to the center of the gap just by press-fitting into the gap between the steel frames. There is no need to spend. In addition, the attachment position of the leg part or the protrusion with respect to the seal part is not limited to the center part, and can be changed according to the positional relationship between the joint position and the gap between the steel frames.
In addition, since the locking part is press-fitted into the gap between the steel frames, the steel frames are joined and stabilized, so the steel frame is placed horizontally on the ground, and a secondary waterstop for joints is attached from above, and the outer wall For example, the panel is attached to the steel frame by bolting, and then the entire structure is set up vertically. In addition, the secondary water-stopping material is attached to the steel frame while the steel frame is set up vertically, and the outer wall panel is bolted to the steel frame. The work of attaching can be easily performed.
Further, since the seal portion is made of EPDM sponge rubber and the leg portion or the protrusion is made of EPDM solid rubber, the sealing function by the seal portion and the function for fixing by the leg portion or the protrusion are sufficiently exhibited. .
[0014]
Further, according to the invention described in claim 2, unlike the invention described in claim 1, the leg or protrusion having a stopper function integrally formed with the seal portion is not press-fitted into the gap between the steel frames. It is inserted into the gap between the steel frames, that is, the width of the leg or protrusion is set narrower than the gap between the steel frames, so it has a function to lock in the gap between the steel frames in particular. However, since it has a stopper function, even if the secondary water-stopping material for joints is displaced with respect to the steel frame, the leg portion or the projecting portion comes into contact with the steel frame and positioning is performed there.
The attachment is performed by placing the steel frame horizontally on the ground, attaching the secondary waterstop material for joints from above, and further attaching the outer wall panel to the steel frame by bolting and then setting the whole vertically.
Further, since the seal portion is made of EPDM sponge rubber and the leg portion or the protrusion is made of EPDM solid rubber, the sealing function by the seal portion and the function for fixing by the leg portion or the protrusion are sufficiently exhibited. .
[0015]
Furthermore, according to the invention described in claim 3, the seal part and the leg part or the protrusion part are made of EPDM solid rubber, and the members made of EPDM sponge rubber are integrally formed on the outer wall panel side surfaces of both ends of the seal part. Therefore, although it is partially, the sealing performance is improved.
[0016]
According to the invention described in claim 4, the seal part and the leg part or the protrusion part are made of EPDM solid rubber, and the members made of EPDM sponge rubber are integrally formed on the outer wall panel side surfaces of both ends of the seal part. Therefore, although it is partially, the sealing performance is improved.
[0017]
According to the fifth aspect of the present invention, since the seal portion is made of water-expandable rubber, the sealing performance is further improved.
[0018]
Furthermore, according to the invention described in claim 6, since the convex portion is integrally formed on the surface of the seal portion on the outer wall panel side, the misalignment prevention of the secondary water-stopping material for joints between the outer wall panels together with the leg portion or the protrusion portion Can be further improved.
[0019]

The secondary water-stopping material for the joints is fixed and the displacement is easily prevented. Moreover, since the secondary water-stopping material for joints is not directly attached to the steel frame using a double-sided tape or the like, it is easy to detach, and no dust such as release paper is generated. Furthermore, if the legs or protrusions are integrally formed so as to be in the center of the seal part, the center of the secondary waterstop material for joints comes to the center of the gap just by press-fitting into the gap between the steel frames. There is no need to spend.
In addition, since the locking part is press-fitted into the gap between the steel frames, the steel frames are joined and stabilized, so the steel frame is placed horizontally on the ground, and a secondary waterstop for joints is attached from above, and the outer wall For example, the panel is attached to the steel frame by bolting, and then the entire structure is set up vertically. In addition, the secondary water-stopping material is attached to the steel frame while the steel frame is set up vertically, and the outer wall panel is bolted to the steel frame. The work of attaching can be easily performed.
Further, since the seal part is made of EPDM sponge rubber and the leg part or the protrusion part is made of EPDM solid rubber, both the seal part and the leg part or the protrusion part are made of EPDM sponge rubber or EPDM solid rubber. Compared with a thing, the sealing function by a seal part and the function for fixing by a leg part or a protrusion are exhibited effectively.
