［産業上の利用分野］
本考案はコンクリート型枠セパレータに用いら
れる型枠受片に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a form support piece used in a concrete form separator.
［従来の技術及び問題点］
従来、型枠内にコンクリートを打設する際は、
型枠の間隔を一定に保持するため、コンクリート
セパレータを用いる。コンクリートの硬化後、型

タをつたわつて漏水の起きる恐れがある。[Conventional technology and problems] Conventionally, when pouring concrete into formwork,
Concrete separators are used to maintain constant spacing between forms. After the concrete hardens, the formwork is removed, but the concrete separator remains embedded in the concrete. However, due to curing and shrinkage of concrete, a gap is created between the concrete and the separator, which may cause water to leak through the separator.
この漏水防止のために、実開昭54−114318号で

案されている。しかしながらセパレータにいちい
ち止水材をはめこむのは繁雑であり、セパレータ
に装着される型枠受片に止水機能があれば好まし
いが、従来の型枠受片は単なる合成樹脂製であ
り、あまり止水性がない。 In order to prevent this water leakage, Japanese Utility Model Application Publication No. 114318/1983 proposes a separator in which a water-swellable water stop material is fitted. However, it is complicated to fit water-stopping material into the separators one by one, and it would be preferable if the formwork pieces attached to the separators had a water-stopping function, but conventional formwork pieces are simply made of synthetic resin, so There is no water stop property.
［問題点を解決するための手段］
本考案の型枠受片は、水膨潤性物質を装着して
止水性を向上させたもので、外周部にリング状水
膨潤性止水材を装着してなることを特徴とし、さ
らに好ましくは内周部にもリング状水膨潤性止水
材を装着してなるものである。[Means for solving the problems] The formwork receiver of the present invention is equipped with a water-swellable material to improve water-stopping properties, and a ring-shaped water-swellable water-stopping material is attached to the outer periphery. More preferably, a ring-shaped water-swellable water stop material is also attached to the inner circumference.
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,
Examples include acrylic homopolymers or copolymers, polyurethane polymers, cellulose, starch, and modified and crosslinked products thereof.
なか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.
第１図ないし第３図は本考案の型枠受片の実施

れている。 1 to 3 show embodiments of the formwork receiving piece of the present invention, each of which has a roughly cylindrical formwork receiving piece 1 with a ring-shaped water-swellable water-stopping material 2 on the outer periphery and an inner wall of the formwork receiving piece 1. A ring-shaped water-swellable water stop material 2' is attached to the periphery.
本考案の型枠受片（第１図のもの）の使用状態
を第４図に示す。 FIG. 4 shows how the formwork support piece of the present invention (the one shown in FIG. 1) is used.
水膨潤性止水材２によりコンクリートと型枠受
片の間のすきまからの漏水が防止され、水膨潤性
止水材２′により型枠受片とセパレータ軸との間
のすきまからの漏水が防止される。 The water-swellable water stop material 2 prevents water from leaking from the gap between the concrete and the formwork piece, and the water-swellable water stop material 2' prevents water from leaking from the gap between the formwork piece and the separator shaft. Prevented.
