る。``Problems to be solved by conventional technology and ideas'' Water-swellable water-stop materials are used to stop water at concrete joints, but this water-swellable water-stop plate has the property of expanding in all directions. Therefore, it is required to control the expansion only in the desired direction.
このような問題に対し、例えば実開昭52−

る。 For such problems, for example,
No. 27220 proposes a water-stopping material in which a water-swellable material is sandwiched from both sides by a pair of holding members, and Utility Model Application Publication No. 180054/1983 proposes a water-swellable material with an intermediate layer made of water-swellable rubber. A water stop material has been proposed in which non-water swellable rubber layers sandwiching the water stop material are formed in a striped pattern.
しかしながら、このようなタイプの止水材は、
これを止水すべき目地に装着しようとすると、挿
入が難かしく、効率的な作業ができない欠点があ

き、装着作業が効率的に行える。 According to this, the expansion of the water-swellable material 1 is absorbed by the foam material 2, deformation in the lateral direction is suppressed, and expansion occurs only in the vertical direction. Inserting into the joint from the foam side allows for smooth insertion and more efficient installation work.
さらにフオーム状物質により、必要以上のシー
ル材の膨張が抑制されるので、硬化したコンクリ
ートにひび割れがでない。 Furthermore, the foam material prevents the sealant from expanding more than necessary, so that the hardened concrete does not crack.
［考案の効果］
本考案の複合シール材により改善された点は以
下の通りである。[Effects of the invention] The points improved by the composite sealing material of the invention are as follows.
膨張が主として縦方向にのみ起こり、横方向
の膨張は、フオーム状物質により吸収される。 Expansion occurs primarily only in the longitudinal direction; lateral expansion is absorbed by the foam.
目地への挿入が極めてスムーズに行うことが
できる。 Insertion into joints can be performed extremely smoothly.
コンクリート固定後、ひび割れの発生がフオ
ーム状物質により抑制される。 After fixing concrete, the occurrence of cracks is suppressed by the foam material.
