Description

콘크리트 구조물용 후 팽창형 지수재{late expansion typed water stopper for concrete structure}Late expansion type indexer for concrete structures

본 고안은 선타설 콘크리트와 후타설 콘크리트와의 틈으로 물(액체)이 유입 또는 누수되는 것을 억제하는 수팽창성 지수재에 관한 것이며, 특히 콘크리트가 양생된 후의 지수성을 강화한 콘크리트 구조물용 지수재에 관한 것이다.The present invention relates to a water-expandable index member that suppresses the inflow or leakage of water (liquid) into the gap between pre-pouring concrete and post-pouring concrete. It is about.

도 3에서, 콘크리트 옹벽의 예를 들어 설명하자면, 선시공한 콘크리트 바닥 또는 기초(1) 위에 콘크리트 옹벽(2)을 후타설하기 전에 콘크리트 기초(1)의 상면에서 대략 그 폭의 중간쯤에 콘크리트 기초의 길이방향을 따라 지수재(3)를 배치하고 그 콘크리트 기초(1) 위에 콘크리트 옹벽(2)을 시공함으로서 콘크리트 기초(1)와 콘크리트 옹벽(2)간의 틈으로 지하수가 새어 나오지 못하도록 방지하게 된다.In FIG. 3, for example, the concrete retaining wall will be described, before the post-casting of the concrete retaining wall 2 onto the pre-installed concrete floor or foundation 1, the concrete foundation at about the middle of its width at the top surface of the concrete foundation 1. By placing the index member (3) along the longitudinal direction of the construction and the concrete retaining wall (2) on the concrete foundation (1) to prevent groundwater from leaking into the gap between the concrete foundation (1) and the concrete retaining wall (2) .

이러한 용도를 가진 지수재는 수분을 머금게 되면 체적이 늘어나서 그 팽창력으로 틈을 메워 지수기능을 발휘하는 이른바 수팽창성 지수재다.A water repellent having such a purpose is a so-called water-expandable water repellent that exhibits a water exponential function by filling a gap with its expansion force when the water is contained.

도 4에서 보는 바와 같이 종래의 수팽창성 지수재(3)는 콘크리트를 타설할 때 초기에 그 콘크리트에 함유된 수분을 흡수하여 팽창되었다가 타설한 콘크리트가 양생되면 지수재도 같이 건조되어 수축되기 때문에 지수성이 약화되는 것이 맹점이다.As shown in FIG. 4, the conventional water-expandable index member 3 expands by absorbing moisture contained in the concrete at the time of placing concrete and then expands when the poured concrete is cured. Weak spots are a blind spot.

본 고안은 재래형 수팽창성 지수재의 단점을 개선한 것이다. 즉, 콘크리트가 양생된 후에 물을 주입하여 팽창시키는 이른바 선시공 후팽창형 지수재로 탈바꿈시킴으로서 선팽창 후수축에 기인하던 종래 지수재의 지수기능 약화현상을 근본적으로 해소한 것이다.The present invention improves the disadvantages of conventional water-expandable index materials. In other words, by transforming into a so-called pre-expanded post-exposure index material that expands by infusing water after curing, concretely solves the phenomenon of weakening of the exponential function of conventional index materials due to post-expansion contraction.

이 수팽창성 지수재는 수팽창성 지수재의 외주면을 합성수지나 고무와 같이 탄성을 지닌 비투수성 코팅재로 피복하여 콘크리트를 타설할 때는 그 콘크리트의 수분을 일절 흡수치 못하게 하고, 콘크리트가 양생된 후에는 수팽창성 지수재의 중앙부에 경질의 유공관을 삽입하여 형성된 구멍을 통하여 물을 강제 주입하게 되면 수팽창성 지수재가 팽창됨으로서 콘크리트 구조물간의 틈을 완벽하게 메우도록 구성한 것이 특징이다.The water-expandable index material covers the outer circumferential surface of the water-expandable index material with a non-permeable coating material such as synthetic resin or rubber that prevents water from being absorbed at all when pouring concrete. When water is forcibly injected through a hole formed by inserting a hard perforated tube in the center of the ash, the water-expandable index member expands to completely fill the gap between the concrete structures.

10 : 후팽창형 지수재 11 : 코팅재10: post-expansion index material 11: coating material

도 1과 도 2에서, 신형 수팽창성 지수재(10)는 단면의 중심에 경질의 유공관(4)을 삽입한 지수재(3)를 바탕으로 하되 그 외주면 전반에 걸쳐 코팅재(11)로 피복한 것이다. 코팅재(11)는 유연성 합성수지 또는 고무이고, 비투수성이다.In Figures 1 and 2, the new water-expandable index member 10 is based on the index member 3 into which the hard perforated tube 4 is inserted at the center of the cross section, and is coated with the coating member 11 over the entire outer peripheral surface thereof. will be. The coating material 11 is flexible synthetic resin or rubber and is water impermeable.

이 지수재(10)도 도 3과 같이 통상의 방법으로 선시공한 콘크리트 기초(1) 위에 그 길이방향으로 배치하고 콘크리트 옹벽(2)을 시공한다. 옹벽용 콘크리트를 타설하더라도 이때는 지수재(10)는 팽창되지 않는다. 지수재(10)의 외주면에 피복된 코팅재(11)가 옹벽용 콘크리트에 함유되어 있는 수분을 흡수할 수 없도록 차단하기 때문이다.This index member 10 is also arrange | positioned in the longitudinal direction on the concrete foundation 1 previously constructed by the conventional method like FIG. 3, and the concrete retaining wall 2 is constructed. Even if the retaining wall concrete is poured, the index member 10 is not expanded at this time. This is because the coating material 11 coated on the outer circumferential surface of the water stopper 10 prevents the moisture contained in the retaining wall concrete from being absorbed.

본격적인 지수작용은 콘크리트 옹벽(2)이 양생된 후에 나타난다. 이것은 큰크리트 옹벽(2)이 양생되고 나서 경질의 유공관(4)을 통하여 강제로 물을 주입, 팽창시켜 콘크리트 기초(1)와의 틈새를 메우게 함으로서 가능해진다. 즉, 콘크리트 타설할 당시에 팽창되었다가 콘크리트가 양생되면 건조 수축되어 지수성을 발휘하지 못하는 종래의 선팽창 후수축성 지수재와는 전혀 다른 개념인 수팽창성 지수재로서, 지수성이 탁월하다.Full-scale exponential action occurs after the concrete retaining wall 2 is cured. This can be done by forcibly injecting and expanding water through the hard oil hole tube 4 after the large concrete retaining wall 2 is cured to fill the gap with the concrete foundation 1. That is, it is a water-expandable index material, which is a completely different concept from the conventional linear expansion post-shrinkage index material that does not exhibit exponentiality when it is expanded at the time of concrete pouring and the concrete is cured.

이상 설명한대로 본 고안의 지수재는 콘크리트를 타설할 때는 그 콘크리트에 함유된 수분을 흡수하지 못하여 팽창되지 않고 타설한 콘크리트가 양생된 후 물의 강제 주입으로 팽창되어 지수역할을 하도록 구성한 것으로, 선팽창 후수축에 기인하던 종래 지수재의 지수성 약화현상을 근본적으로 해소할 수 있고, 지수성도 선팽창성 후수축성 지수재보다 월등하다.As described above, the index member of the present invention does not absorb the moisture contained in the concrete when it is poured, and it is configured to be expanded by the forced injection of water after it is cured. It is possible to fundamentally solve the exponential deterioration of the conventional index material, which is also superior to the linear expandable post-shrinkage index material.
