Abstract

본 발명의 목적은 지하옹벽 구축시 지하수 유입을 차단하기 위한 목적으로 수팽창성 고무 지수재를 설치함에 있어 기존제품의 성능을 개선하고 작업이 매우 간편하고 인건비와 시간이 절약 된다.An object of the present invention is to improve the performance of the existing product in the installation of water-expandable rubber index material for the purpose of blocking the groundwater inflow when building the basement retaining wall, very easy to work and save labor cost and time.

(1) 기존의 수팽창성 고무 지수재는 수팽창성 가황고무로 되어있어 현장에서 1차 콘크리트 타설 후 지수재 설치시 콘크리트면이 일정치 못하고 요철이 많아 지수재가 콘크리트에 밀착되지 못하여 지수성을 의심 받아 왔다(1) Existing water-expandable rubber index material is made of water-expandable vulcanized rubber, so it has been suspected that the index material could not adhere to concrete due to the irregularity of concrete surface and unevenness when installing the index material after the first concrete placement at the site.

(2) 지수재 설치시 30cm 간격으로 못을 박아 고정하기 때문에 비가 오면 팽창하면서 콘크리트 못 과 못 사이에 구속되어 접지 콘크리트면에서 들뜸현상이 발생하여 문제시되어왔다.(2) When installing the exponent materials, the nails are fixed at 30cm intervals, so when it rains, it expands and binds between the concrete nails and the nails.

본 발명은 수팽창고무 하단부에 접착성과 유연성이 뛰어난 부틸변성고무를 합성하여 제작되므로 콘크리트면에 직접 눌러가며 부착하여 요철부위를 메꾸어 주므로 (1)의 문제점을 해결하고, 콘크리트 못으로 고정시키지 않으므로 구속되지 않고 상단부의 팽창고무가 물에 팽창시 하단부의 부틸변성고무도 팽창력에 대응하여 신축하므로 들뜸현상이 생기지 않는다. 이로써 (2)의 문제점을 해결한다.The present invention synthesizes butyl-modified rubber having excellent adhesion and flexibility at the bottom of the water-expandable rubber, so it is pressed directly onto the concrete surface to fill the uneven part, thereby solving the problem of (1) and restraining it because it is not fixed with concrete nails. When the expansion rubber of the upper part expands in water, the butyl-modified rubber of the lower part also expands and contracts in response to the expansion force, so that no lifting phenomenon occurs. This solves the problem of (2).

Description

수팽창성 수밀형 고무 지수재Water-expandable watertight rubber index material

콘크리트 신축 이음부위(3)에 지수재를 설치시 표면에 요철이 많아 기존 수팽창성 고무 지수재로는 도 2에 도시하는것과 같이 콘크리트의 요철부위에 밀착이 이루어 지지않아 완벽한 지수성능을 발휘하지 못했다.When installing the exponent in the concrete expansion joint part (3), there were many irregularities on the surface, so the existing water-expandable rubber index material did not show the perfect exponential performance because it was not in close contact with the uneven part of the concrete as shown in FIG. .

본고안은 이문제점을 해결 하기위한 구성.This paper is structured to solve this problem.

기존의 수팽창성 고무지수재는 수팽창력, 인장력, 탄성 등에 장점이 있으나 도2가 도시하는바와 같이 콘크리트 요철부위(4)와 밀착되어야하는 문제점을 해결하지 못했다Existing water-expandable rubber index material has advantages such as water expansion force, tensile force, elasticity, but did not solve the problem that should be in close contact with the concave-convex portion 4 as shown in FIG.

수팽창성 고무 지수재의 팽창력과 인장력, 탄성을 유지하면서 콘크리트 요철부위와 밀착시키고, 팽창시 들뜸현상으로 인한 수밀성 저하를 방지하는 방법.A method of maintaining the expansion force, tensile force and elasticity of a water-expandable rubber index material in close contact with concave-convex portions, and preventing water-tightness deterioration due to lifting during expansion.

대표도는 수팽창성 수밀형 지수재의 사시도Representative view is a perspective view of a water-expandable watertight index member

도 1은 본발명 수팽창성 수밀형 지수재의 사용상태를 설명하는 도면1 is a view for explaining the state of use of the water-expandable watertight index member of the present invention

도 2는 종래 수팽창성 고무 지수재의 사용상태를 설명하는 도면2 is a view for explaining a state of use of the conventional water-expandable rubber index material

※ 도면의 주요 부분에 대한 부위의설명※ Description of parts about main parts

1 : 수팽창성고무1: water-expandable rubber

2 : 부틸 변성 고무2: butyl modified rubber

3 : 콘크리트3: concrete

4 : 공극4: void

5 : 콘크리트 못5: concrete nail

수팽창성 고무 지수재 하단부위에 접착력과 신장률이 뛰어난 부틸변성고무(2)를 합성한 제품으로 콘크리트에 접착시 요철부위에 따라 지수재가 변형되어 요철을 메꾸어주고 콘크리트못(5)에 의한 구속력이 없어 팽창고무(1)가 팽창할 때 하단부의 부틸변성고무(2)도 팽창력에 대응하여 신,수축함에 따라 들뜸현상이 일어나지 않고 도 1처럼 콘크리트 면에 접착이 좋아 지수성능도 향상된다.Synthetic butyl-modified rubber (2) with excellent adhesion and elongation at the lower end of water-expandable rubber index material. The product is transformed according to the uneven part when it is bonded to concrete, filling the unevenness and expanding because there is no binding force by concrete nail (5). When the rubber 1 expands, the butyl-modified rubber 2 at the lower end also expands and contracts in response to the expansion force, so that no lifting occurs and adhesion to the concrete surface as shown in FIG. 1 improves the index performance.

지수재 설치시 부틸변성고무가 콘크리트의 요철부위를 메꾸어 주면서 부착되므로 설치가 간편하고 인건비와 시간이 절약되며 수밀성과 지수성능이 증대된다. 또한 이로인하여 비가 올 때 팽창하면서 접지면에서 이탈되는 이탈현상도 생기지 않으므로 지수성능이 증대된다.(도 1참고)Butyl modified rubber is attached while filling the uneven part of concrete when installing the index material, so installation is easy, labor cost and time are saved, and watertightness and index performance are increased. In addition, the exponential performance is increased because it does not occur the separation phenomenon from the ground plane while expanding when it rains (see Fig. 1).
