【考案の詳細な説明】
本考案は止水板に関する。詳しくは、本考案は
主体部分に断面波型のひだが形成されている波型
止水板に関する。[Detailed Description of the Invention] The present invention relates to a water stop plate. More specifically, the present invention relates to a corrugated water stop plate having corrugated pleats formed in its main portion.
打設されたコンクリート構造物等のすき間の止
水のために止水板が用いられるが、一担構築され
たコンクリート構造物等は、長期的には、不等沈
下又はその他の理由で若干のずれを生じる。その
ようなずれが生じると止水板の止水機能が低下
し、ついには全く止水性が失なれるに至る。 Water stop plates are used to stop water in gaps in poured concrete structures, etc., but over the long term, concrete structures built in one layer may suffer some damage due to uneven settlement or other reasons. This causes misalignment. When such a shift occurs, the water-stopping function of the water-stop plate deteriorates, and eventually the water-stopping property is completely lost.
本考案の目的は、かかる欠陥をなくし、コンク
リート構造物にずれが生じ、間隙が拡大すること
があつても止水性の低下しない止水板を提供する
ことにある。 The purpose of the present invention is to eliminate such defects and to provide a water stop plate whose water stop performance does not deteriorate even if the concrete structure is displaced and the gap is enlarged.
本考案の止水板は、長手方向の一側縁に水膨潤
性物質からなる膨出部を設け、他の一側縁に断面
略Ｃ字形の腕部を設けて該腕部の溝に水膨潤性物
質からなる止水材を装着するとともに伸縮性を有
する材料で形成された主体部分に断面波型の複数
のひだを形成せしめてなるものである。 The water stop plate of the present invention is provided with a bulge made of a water-swellable substance on one longitudinal edge, an arm portion having a substantially C-shaped cross section on the other side edge, and a groove in the arm portion that allows water to flow through the groove. A waterproof material made of a swellable substance is attached, and a plurality of folds with a corrugated cross section are formed on the main portion made of a stretchable material.
本考案の止水板の実施態様を第１図及び第２図
に示す。 An embodiment of the water stop plate of the present invention is shown in FIGS. 1 and 2.
１は、一側縁に形成された水膨潤性物質からな
る膨出部で、かかる膨出部は、第１図のように止
水板主体と一体に形成されていてもよいが、第２
図のように、水膨潤性物質からなる皮膜を止水板
主体に形成せしめてもよい。 Reference numeral 1 denotes a bulge made of a water-swellable substance formed on one side edge. This bulge may be formed integrally with the main body of the water stop plate as shown in FIG.
As shown in the figure, a film made of a water-swellable substance may be formed mainly on the water stop plate.
また２は、他の一側縁に形成された断面略Ｃ字
形の腕部で、該腕部の溝には水膨潤性物質からな
る止水材３が装着されている。止水材３は、はめ
込み式にすると水場でも使用直前にセツトすれば
使用できるので好ましい。 Further, reference numeral 2 denotes an arm portion having a substantially C-shaped cross section formed on the other side edge, and a water stop material 3 made of a water-swellable substance is attached to a groove of the arm portion. It is preferable that the water stop material 3 is a built-in type because it can be used at a water place by setting it immediately before use.
上記水膨潤性物質としては、例えば、ビニル
系、アクリル系の単一重合体もしくは共重合体、
ポリウレタン系重合体、セルロース、デンプン又
はその変性物、架橋物等が挙げられる。 Examples of the water-swellable substance include vinyl-based or acrylic-based homopolymers or copolymers;
Examples include polyurethane polymers, cellulose, starch, modified products thereof, and crosslinked products.
中でも好ましいものは水膨潤性ポリウレタン含
有可撓性物質であり、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撓性物質である。 Among these, preferred are flexible materials containing water-swellable polyurethane, and particularly preferred are flexible materials comprising a mixture of water-swellable polyurethane and natural rubber, synthetic rubber, recycled rubber, or the like.
また４は、止水板主体で、合成樹脂、ゴム等で
形成されるが、ゴムのような伸縮性のある材料で
形成されるのが好ましい。止水板主体４には複数
のひだが形成されている。 Further, 4 is mainly a water stop plate and is made of synthetic resin, rubber, etc., but preferably made of a stretchable material such as rubber. A plurality of pleats are formed in the water stop plate main body 4.
本考案の波型止水板の使用例を第３図に従い説
明する。 An example of the use of the corrugated water stop plate of the present invention will be explained with reference to FIG.
１，１′はコンクリート構造物で、この間のす
き間を止水する。１，１′の間のすき間にフオー
ム状物質２，２′を充填し、本考案の波型止水板
３を装着する。 1 and 1' are concrete structures, and the gap between them is water-tight. The gap between 1 and 1' is filled with foam material 2 and 2', and the corrugated water stop plate 3 of the present invention is attached.
波型止水板３は、膨出部をコンクリート構造物
中に埋め込んだ形で装着される。止水板３は、一
方のコンクリート構造物１′に膨出部が埋め込ま
れ、しかも多くの場合主体部分がやや圧縮された
形で装着されるのが普通であるから、その腕部は
他方のコンクリート構造体１にほとんど固定され
るけれども、所望によつては接着剤などを用い
て、腕部を固定してもよい。 The corrugated water stop plate 3 is installed with the bulge portion embedded in the concrete structure. The water stop plate 3 has a bulging part embedded in one concrete structure 1', and in many cases, the main part is usually installed in a slightly compressed form, so its arm part is attached to the other concrete structure 1'. The arms are mostly fixed to the concrete structure 1, but if desired, the arms may be fixed using an adhesive or the like.
止水板３は、１，１′の間のすき間が拡大ある
いは縮少することがあつても十分追随できる伸縮
性を有しているので、長期にわたつて止水性が低
下することはない。 Since the water stop plate 3 has sufficient elasticity to follow the expansion or contraction of the gap between 1 and 1', the water stop performance will not deteriorate over a long period of time.
