Description
【０００１】
【産業上の利用分野】
本発明は、例えばプレハブ住宅のコーナ部の入り隅部や出隅部等における防水施工に用いられる建築用防水シートに関する。
【０００２】
【従来の技術】
従来、この種の入り隅部や出隅部等における防水施工には、ゴムやプラスチックを入り隅部や出隅部等の形状に合わせて金型成形した定形役物を用いるか、ゴムシートや塩ビシート等の防水シートに切り込みを入れて継ぎ合わせて定形加工したものを用いるか、或いは、無定形シーリング材を塗布したりしていた。
【０００３】
【発明が解決しようとする課題】
しかしながら、前記金型成形による定形役物を用いる場合は、原料費は安いが、金型のコストが大きく、役物は通常小量で多品種なので、コストに合わないという不都合を有する。また、シートに切り込みを入れて継ぎ合わせ加工する場合は、切り込みや継ぎ目があるため、防水性が十分でないという不都合を有する。更にまた、無定形シーリング材を用いる場合には、作業者の熟練度により防水精度にバラツキが生じてしまい常に一定した防水施工を行えないという不都合を有する。
本発明はかかる従来の不都合を解消し、施工性、防水性に優れる建築用防水部材として用いられる防水シートを提供することを目的とする。
【０００４】
【課題を解決するための手段】
本発明の建築用防水ゴムシートは、前記目的を達成するべく、段差を備えた入り隅部の形状に合わせて折り曲げ可能なゴムシートの裏面に引き布を裏打し、該裏面に入り隅部に貼着するための粘着部を設けると共に、前記ゴムシートの表面に該ゴムシートを前記入り隅部の形状に合わせて折り曲げた際に鉛直方向に形成される折り皺を貼着するために、前記ゴムシートの下端に粘着部を設け、前記折り皺を前記ゴムシートの表面に貼着したことを特徴とする。
また、本発明の建築用防水ゴムシートは、段差を備えた出隅部の形状に合わせて折り曲げ可能なゴムシートの裏面に引き布を裏打し、該裏面に出隅部を貼着するための粘着部を設けると共に、前記ゴムシートの表面に該ゴムシートを前記出隅部の形状に合わせて折り曲げた際に鉛直方向に形成される折り皺を貼着するために、前記ゴムシートの上端に粘着部を設け、前記折り皺を前記ゴムシートの表面に貼着したことを特徴とする。
尚、前記引き布にはゴム糊が含浸されていることが好ましい。
また、前記各粘着部は両面粘着テープの貼着により形成することが好ましい。
【０００５】
【作用】
ゴムシートの裏面に引き布を裏打したため、ゴムシートの弾性を押さえることができ、コーナ部におけるコーナの形状に合わせた貼着作業が容易に行える。
また、ゴムシートの裏面に入り隅部或いは出隅部に貼着するための粘着部を設けたため、かかる粘着部を利用してゴムシートをコーナ部に簡単に貼着できる。また、入り隅部或いは出隅部の形状にあわせて折り曲げた際に形成される折り皺を前記ゴムシートに貼着するための粘着部を設けたため、この折り皺の貼着のみでゴムシートをコーナ部の形状に合わせて、所定形状のまま簡単に固定することができる。
また、引き布にゴム糊を含浸させた場合、引き布とゴムシートは極めて良好に一体化され、また、引き布自体にも防水性が与えられ、ゴムシートは極めて防水性の高いものとなる。
【０００６】
【実施例】
以下、本発明の実施例を図面に基づき説明する。
図１乃至図３は本発明の建築用防水シートの一実施例を示すもので、図１はその正面図、図２は図１のＡ−Ａ断面図、図３は前記ゴムシートの斜視図を示すもので、本実施例では入り隅用に構成した例を示す。
前記建築用防水シートはゴムシート１の裏面にポリエステル製の織布２を裏打ちし、この織布２にゴム糊を含浸させたもので、前記ゴムシート１の厚みは０．３ｍｍ、前記織布２の厚みは０．２ｍｍ程度としてある。
前記ゴムシート１の裏面、即ち織布２側にはその上端部に沿って、両面粘着テープによる粘着部３が形成され、また、前記ゴムシート１の表面中央部下端には、ゴムシート１を入り隅部の形状に合わせて折り曲げた際に形成される折り皺４を貼着するための両面粘着テープによる粘着部５が形成されている。
【０００７】
図４は、前記建築用防水シートの施工状態を示すもので、ベニヤ板１０による段差を備えた入り隅部１１に適用した例を示すもので、裏面の粘着部３を利用してゴムシート１を壁２０に貼着すると共に、ベニヤ板１０の段差部においてゴムシート１を折り曲げてその折り皺４を表面の粘着部５を利用してゴムシート１に貼着することで、入り隅部１１の形状に合わせて建築用防水シートを防水施工したものである。
【０００８】
図５乃至図７は本発明の建築用防水シートの他実施例を示すもので、図５はその正面図、図６は図１のＢ−Ｂ断面図、図７は折り曲げた状態の斜視図をを示すもので、本実施例では出隅用に構成した例を示す。
本実施例の建築用防水シートは、ゴムシート１の表面中央部上端に、ゴムシート１を出隅部の形状に合わせて折り曲げた際に形成される折り皺４を貼着するための両面粘着テープによる粘着部５を形成するようにした以外は前記実施例と同様の構成であるので、同一部材には同一符号を付してその詳細な説明は省略した。
【０００９】
図８は、前記建築用防水シートの施工状態を示すもので、ベニヤ板１０による段差を備えた出隅部１２に適用した例を示すもので、裏面の粘着部５を利用してゴムシート１を柱３０に貼着すると共に、柱面においてゴムシート１を折り曲げてその折り皺４を表面の粘着部５を利用してゴムシートに貼着することで、出隅部１２の形状に合わせて建築用防水シートを防水施工したものである。
尚、前記施工例では、ゴムシートをコーナ部において施工時にその形状に合わせて折り曲げるようにしたが、予めコーナ部の形状に折り曲げておいてから、コーナ部に施工するようにしてもよい。
【００１０】
【発明の効果】
このように本発明によれば、施工性と防水性に優れた建築用防水シートが得られる。

[Industrial applications]
The present invention relates to an architectural waterproof sheet used for waterproofing, for example, at a corner or an outside corner of a corner of a prefab house.
[0002]
[Prior art]
Conventionally, for waterproofing at the entrance corner or the outside corner of this kind, a fixed-shaped part formed by molding rubber or plastic to the shape of the entrance corner or the outside corner, etc. is used, or a rubber sheet or the like is used. A waterproof sheet such as a polyvinyl chloride sheet is cut and spliced to form a fixed sheet, or an amorphous sealing material is applied.
[0003]
[Problems to be solved by the invention]
However, in the case of using the fixed shaped articles by the molding, the cost of the raw materials is low, but the cost of the mold is large. Further, when the sheet is cut and seamed, there is an inconvenience that the waterproofness is not sufficient because there are cuts and seams. Furthermore, when an amorphous sealing material is used, there is a disadvantage in that the precision of waterproofing varies due to the skill level of the operator, and constant waterproofing cannot always be performed.
An object of the present invention is to solve the conventional inconveniences and to provide a waterproof sheet used as a waterproofing member for construction which is excellent in workability and waterproofness.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, the architectural waterproof rubber sheet of the present invention has a backing lined on the back surface of the rubber sheet that can be bent in accordance with the shape of the stepped corner, and enters the back surface into the corner. Along with providing an adhesive portion for sticking, in order to stick a fold wrinkle formed in a vertical direction when the rubber sheet is bent in accordance with the shape of the entering corner on the surface of the rubber sheet , An adhesive portion is provided at a lower end of the rubber sheet, and the fold is attached to a surface of the rubber sheet.
Further, the waterproof rubber sheet for construction of the present invention is for backing a pulling cloth on the back surface of a rubber sheet that can be bent in accordance with the shape of the projected corner portion having a step, and attaching the projected corner portion to the back surface. Along with providing an adhesive portion, in order to attach a crease formed in a vertical direction when the rubber sheet is bent in accordance with the shape of the protruding corner portion on the surface of the rubber sheet, at the upper end of the rubber sheet An adhesive portion is provided, and the fold is attached to a surface of the rubber sheet.
It is preferable that the cloth is impregnated with rubber paste.
Further, it is preferable that each of the adhesive portions is formed by sticking a double-sided adhesive tape.
[0005]
[Action]
Since the backing of the rubber sheet is lined with the drawing cloth, the elasticity of the rubber sheet can be suppressed, and the sticking operation according to the shape of the corner at the corner can be easily performed.
In addition, since the adhesive portion is provided for sticking to the corner portion or the protruding corner portion of the rubber sheet on the back surface, the rubber sheet can be easily attached to the corner portion using the adhesive portion. In addition, since an adhesive portion is provided for sticking a fold formed on the rubber sheet when the fold is formed in accordance with the shape of the entering corner or the outside corner, the rubber sheet can be formed only by sticking the fold. According to the shape of the corner portion, it can be easily fixed in a predetermined shape.
Also, when the cloth is impregnated with rubber paste, the cloth and the rubber sheet are very well integrated, and the cloth itself is also provided with waterproofness, and the rubber sheet becomes extremely waterproof. .
