Description
【考案の詳細な説明】 「産業上の利用分野」 本考案は水膨潤性複合シール材に関する。[Detailed explanation of the idea] "Industrial application field" The present invention relates to a water-swellable composite sealing material.
「従来の技術と考案が解決しようとする問題点」
コンクリート打継部の止水のため、水膨潤性止
水材が用いられるが、この水膨潤性止水板はあら
ゆる方向に膨張する性質があるため、望む方向の
みに膨張をコントロールすることが求められてい
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59−
27220号によつて、水膨潤体を、一対の保持部材
によつて両側からはさんだ形の止水材が提案され
ているが、このように水膨潤部と非水膨潤部を組
合せたタイプの止水材は、両部が一様に膨張しな
いので（水膨潤部のみ膨張する）好ましい止水材
とはいい難い。 For such problems, for example,
No. 27220 proposes a water-stopping material in which a water-swellable body is sandwiched from both sides by a pair of holding members. Since both parts of the water stop material do not expand uniformly (only the water-swollen part expands), it is difficult to say that it is a desirable water stop material.
本考案の出願人は、このような問題を解決する
ためにのシール材として、既に実開昭60−177205
号のシール材を提案しているが、本考案はそれを
さらに改良したものである。 The applicant of the present invention has already developed a sealing material in 177205 in 1983 to solve such problems.
The present invention is a further improvement on the sealing material of the No.
「問題点を解決するための手段」
本考案の水膨潤性複合シール材は、三層からな

二層が水膨潤性フオーム状物質からなり、中心層
内部に芯体が、芯体の面の方向と積層面に直交す

とを特徴とするものである。``Means for solving the problem'' The water-swellable composite sealing material of the present invention consists of three layers, the center layer of which is a water-swellable material, and the two layers sandwiching the center layer are made of a water-swellable foam material. , a core is embedded within the center layer so that the direction of the surface of the core is the same as the direction of the surface perpendicular to the lamination surface.

得られるもの等が使用できる。 By appropriately blending such water-swellable polyurethane and rubber, a water-swellable material having a desired water-swelling rate can be obtained. Further, as the water-swellable foam material, a material obtained by adding a foaming agent to the rubber-containing water-swellable polyurethane material and foaming it can be used.
本考案の複合シール材の一例は、第１図に示す

案のシール材を取り付け、コンクリートを打設す
ることにより用いられる。 As shown in FIG. 1, an example of the composite sealing material of the present invention has a water-swellable substance 1 as a central layer, and a core 4 within the layer in a direction perpendicular to the surface of the core and the laminated surface. They are buried in the same direction, and the center layer is sandwiched between water-swellable foams 2 on both sides. The core body 4 is arbitrarily selected from rubber, synthetic resin, metal, etc. The sealing material of the present invention is used by attaching the sealing material of the present invention to an existing concrete structure and pouring concrete, as shown in FIG.
「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BB′方向にのみ起こり、
AA′方向の膨張は、芯体によつて制限を受ける
とともに水膨潤性発泡性物質により吸収され
る。なお水膨潤性発泡性物質の膨張も自身が発
泡体のため吸収される。 Expansion mainly occurs only in the BB′ direction,
Expansion in the AA′ direction is limited by the core and absorbed by the water-swellable foamable material. Note that the expansion of the water-swellable foamable material is also absorbed because it is a foam itself.
コンクリート打設時にも、シール材裏側への
コンクリートのまわり込みが発泡体により阻止
される。 Even during concrete pouring, the foam prevents the concrete from going around to the back side of the sealing material.
コンクリート固定後、ひび割れの発生が発泡
体により抑制される。 After concrete is fixed, the foam suppresses the occurrence of cracks.
以上のように、本考案の複合シール材は実用的
に価値の高いものである。 As described above, the composite sealing material of the present invention is of high practical value.
