ごとく目地溝２を三面（両側面、底面）接着する
のを防止し、二面接着として外圧による荷重を受
けた場合など構造物自体にクラツク等を生じるの
を防止している。 By inserting this back-up material 4, it is possible to prevent the joint groove 2 from being glued on three sides (both sides and the bottom) as shown in Figure 2, and to prevent cracks in the structure itself when it is subjected to loads due to external pressure as a two-sided adhesive. Preventing it from occurring.
しかし、上記従来のバツクアツプ材４には防水
作用がないので、これが設置された目地溝２の深
部へ水が浸入してしまうとやはり漏水する恐れが
ある。 However, since the conventional back-up material 4 does not have a waterproof effect, there is a risk of water leakage if water enters the deep part of the joint groove 2 in which it is installed.
本考案の目的は上記不都合を解消し、目地溝の
深部からの漏水の恐れがなく、かつ目地溝を二面
接着できる継手目地構造を提供することにある。 It is an object of the present invention to provide a joint joint structure that eliminates the above-mentioned disadvantages, eliminates the fear of water leakage from the deep part of the joint groove, and allows the joint groove to be bonded on two sides.
しかしてこの目的は本考案によれば、水膨潤性

ことにより達成される。 However, according to the present invention, the purpose of this lever is to extrude a water-swellable composition made of a swellable polymer material such as a water-swellable polyurethane resin or a water-swellable polyvinyl alcohol, and to which a petroleum resin adhesive is added. This is achieved by inserting a molded adhesive string-like back-up material/sealing material deep into the joint joint groove, and then applying an elastic elastic joint sealant over it with a mold release material interposed therebetween.
以下、図面について本考案のの実施例を詳細に
説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
第１図は本考案の目地構造を示す縦断正面図
で、図中１，１′はコンクリート製金属製の継手
構造物を示し、その端面には継手目地溝２を形成
している。 FIG. 1 is a longitudinal sectional front view showing the joint structure of the present invention. In the figure, reference numerals 1 and 1' indicate a joint structure made of concrete and metal, and a joint joint groove 2 is formed on the end face thereof.
この目地溝２の深部に、押し出し成型した可塑

シール材５を挿入し、その上に離型材７を介在さ
せて弾性伸縮目地剤６を施す。 A string-like back-up material/sealing material 5 made of an extrusion-molded plastic water-swellable composition is inserted deep into the joint groove 2, and an elastic elastic joint material 6 is applied thereon with a mold release material 7 interposed therebetween.
上記離型材７はバツクアツプ材兼シール材５の
上面に塗布されるもので、粘着性を有するバツク
アツプ材兼シール材５や伸縮目地剤６の三面接着
を防止し、二面接着を可能とする。また、この離
型材７があることにより、補修その他で伸縮目地
剤６を交換するのに便利である。 The mold release material 7 is applied to the upper surface of the back-up material/sealing material 5, and prevents the three-sided adhesion of the adhesive back-up material/sealing material 5 and the elastic joint sealant 6, and enables two-sided adhesion. Furthermore, the presence of the mold release material 7 makes it convenient to replace the expandable joint sealant 6 for repairs or other purposes.
上記バツクアツプ材兼シール材５を構成する水
膨潤性組成物として、水膨潤性ポリウレタン樹
脂、水膨潤性ポリビニルアルコール等の膨潤性高
分子物質を素材とすることが考えられる。 The water-swellable composition constituting the backup material/sealing material 5 may be made of a swellable polymeric substance such as a water-swellable polyurethane resin or a water-swellable polyvinyl alcohol.
さらにこれら膨潤性高分子物質に熱可塑性エラ
ストマー又は反応性未端基を有する液状ゴム、未
加硫ブチルゴム等を加えてもよい。 Furthermore, a thermoplastic elastomer, a liquid rubber having reactive end groups, unvulcanized butyl rubber, etc. may be added to these swellable polymeric substances.
前記膨潤性高分子物質そのものは粘性を有する

うに液状ゴムや未加流ブチルゴムを加えることに
より組成物として粘性のあるものとなる。特にブ
チルゴムは未加流のものではゴム自体の粘性があ
る。 Although the swellable polymer substance itself does not have viscosity, in the present invention, the water-swellable composition made from it has viscosity. By adding liquid rubber or uncured butyl rubber in this manner, the composition becomes viscous. In particular, butyl rubber has its own viscosity when uncured.
また、さらに粘着剤として石油系樹脂等を加え
て、バツクアツプ材兼シール材５自体に粘着性を
もたせ、端部同士をこの粘着効果で一体化する。 Furthermore, a petroleum-based resin or the like is added as an adhesive to impart adhesiveness to the backup material/sealing material 5 itself, and the ends are integrated with each other by this adhesive effect.
粘着剤としての石油系樹脂等の添加は前記未加
流ブチルゴム等を混ぜた場合は、粘着性を強化す
るためのものである。 The addition of a petroleum resin or the like as an adhesive is to strengthen the adhesiveness when the uncured butyl rubber or the like is mixed.
一方、バツクアツプ材兼シール材５の上部に施
す弾性伸縮目地剤６としては、土木工事ではエポ
