【考案の詳細な説明】
本考案は継手金具に関し、詳しくは止水性の優
れた継手金具に関する。[Detailed Description of the Invention] The present invention relates to a joint fitting, and more particularly to a joint fitting with excellent water-stopping properties.
継手金具はコンクリートセグメント等に埋めこ
んで、セグメントを固着させる働きをもつもので
あるが、セグメント相互間に漏水が起こることが
あり、問題となつていた。 Joint fittings are embedded in concrete segments, etc., and have the function of fixing the segments, but water leakage may occur between the segments, which has been a problem.
今までは、この部分にエポキシ樹脂等を塗布し
て処理していたが、確実に漏水を防止することは
難かしかつた。 Until now, this area had been treated with epoxy resin, etc., but it was difficult to reliably prevent water leakage.
本考案の継手金具は、脚部にコンクリートセグ

セグメント表面に露出する継手金具底面から所定
長さだけ入つた金具くびれ部に水膨潤性ポリウレ
タン含有可撓性物質からなるシール材が装着され
てなることを特徴とする。 The joint fitting of the present invention has a leg part for a concrete segment, and when the joint metal fitting is buried in a concrete segment, water can enter the narrow part of the metal fitting for a predetermined length from the bottom of the joint metal exposed on the surface of the concrete segment. It is characterized by being equipped with a sealing material made of a flexible material containing swellable polyurethane.
本考案の継手金具は、コンクリート中に埋めこ
まれて金具とコンクリートの間にすきまができて
水が侵入してきた場合でも、水膨潤性ポリウレタ
ン含有可撓性物質からなるシール材が水と接触す
ると膨張し、すきまをふさぐのでそれ以上の水の
侵入が阻まれる。 Even if the fitting of the present invention is embedded in concrete and a gap is created between the fitting and the concrete and water enters, the sealing material made of a flexible material containing water-swellable polyurethane will not come in contact with water. It expands and closes the gap, preventing further water from entering.
水膨潤性ポリウレタン含有可撓性物質として、
特に好ましいのは、水膨潤性ポリウレタンと天然
ゴム、合成ゴム、もしくは再生ゴム等の混合物か
らなる可とう性物質である。 As a flexible material containing water-swellable polyurethane,
Particularly preferred is a flexible material made of a mixture of water-swellable polyurethane and natural rubber, synthetic rubber, recycled rubber, or the like.
以上のように、本考案の継手金具はセグメント
に埋めこんでも止水性が優れており、実用性の高
いものである。 As described above, the joint fitting of the present invention has excellent water-stopping properties even when embedded in a segment, and is highly practical.
