따라서 교량 이음부재(10) 내부 양측에 형성된 가이드부재(11)에 수밀고무부재(20)의 중공형 플랜지(21)를 끼우고 보조날개(22)는 가이드부재(11) 상단부가 덮어지도록 설치함으로서, 가이드부재와 가이드부재 사이의 수밀을 유지시켜 빗물 등이 유입되는 것을 방수할 수 있게 된다. 도 3은 일측 가이드부재(11)에 수밀고무부재(20)가 끼워진 상태를 발췌하여 확대 도시한 것이다. Therefore, the hollow flange 21 of the watertight rubber member 20 is inserted into the guide members 11 formed on both sides of the bridge joint member 10 and the auxiliary wings 22 are installed to cover the upper end of the guide member 11. By maintaining the watertight between the guide member and the guide member, it is possible to waterproof the rain water and the like. 3 is an enlarged view showing the state where the watertight rubber member 20 is fitted to one side guide member 11.

또한, 교량 이음부재(10) 외면에는 다수의 고정부재(12)가 구비되어 상판(13) 내에 매립되도록 설치됨으로 교량 이음부재(10)는 견고하게 설치된다. In addition, a plurality of fixing members 12 are provided on the outer surface of the bridge joint member 10 so as to be embedded in the upper plate 13 so that the bridge joint member 10 is firmly installed.

도 4는 본 발명에 따른 수밀고무부재 상면 양측에 형성된 보조날개가 수팽창고무로 형성된 상태의 예시도이고, 도 5는 본 발명에 따른 교량 이음부재 내측에 형성된 가이드부재에 수밀고무부재가 설치어 보조날개가 물에 의해 팽창된 상태의 예시도 이며, 도 6은 본 발명에 따른 수밀고무부재가 수팽창고무로 이루어져 물을 흡수한 상태의 예시도 이고, 도 7은 본 발명에 따른 교량 이음부재 내측에 형성된 가이드부재에 수밀고무부재가 설치어 물을 흡수여 기밀을 유지한 상태를 나타낸 예 시도이다.Figure 4 is an exemplary view showing a state in which the auxiliary wings formed on both sides of the upper surface of the watertight rubber member according to the present invention is formed of water-expanded rubber, Figure 5 is a watertight rubber member is installed on the guide member formed inside the bridge joint member according to the present invention Figure 6 is an exemplary view showing a state in which the auxiliary wing is inflated by water, Figure 6 is an illustration of a state in which the watertight rubber member according to the present invention made of water-expanded rubber to absorb water, Figure 7 is a bridge joint member according to the present invention This is an example of a state in which a watertight rubber member is installed on a guide member formed inside to absorb water to maintain airtightness.

즉, 도4는 수밀고무부재(20)의 보조날개(22)를 수팽창고무로 형성하여 수분이나 물을 접촉하면 보조날개(22)가 팽창되도록 한 것이다.That is, Figure 4 is to form the auxiliary blade 22 of the water-tight rubber member 20 to the water-expanded rubber so that the auxiliary wing 22 is expanded when contacted with water or water.

따라서 보조날개(22)를 수팽창고무로 형성하여 도 5와 같이 가이드부재(11)에 설치하면 우천시 빗물이 유입되거나 또는 외부에서 물이 유입되어 보조날개(22)와 접촉되면 물이 흡수되는 동시에 팽창되어 플랜지(21)와 보조날개(22) 사이에 위치한 가이드부재(11) 상단부가 보조날개(22)와 더욱 밀착되어 방수효과가 증진되도록 한 것이다.Therefore, when the auxiliary wing 22 is formed of water-expanded rubber and installed in the guide member 11 as shown in FIG. 5, when rain water flows in rainy weather or water is introduced from the outside to contact the auxiliary wing 22, the water is absorbed. The upper end of the guide member 11 located between the flange 21 and the auxiliary wing 22 is expanded to be in close contact with the auxiliary wing 22 to enhance the waterproof effect.

도 6은 수밀고무부재의 몸체 전체를 수팽창고무로 형성하여 도 7과 같이 가이드 부재에 설치하겐 된다.Figure 6 is formed by the entire body of the water-tight rubber member water-expanded rubber is installed in the guide member as shown in FIG.

상기와 같이 설치된 수밀고무부재(20)는 우천시 빗물이나 물과 접촉하면 가이드부재에 끼워져 플랜지(21)가 팽창되어 가이드부재(11) 내부와 밀착된다. 이때 플랜지(21)는 중공형으로 형성되어 수분과 접촉시 풍선이 부풀어 오르는 것과 같이 팽창되어 가이드부재(11) 내면에 밀착되어 방수될 수 있도록 하는 동시에 보조날개(22) 역시 수분에 위해 팽창되어 가이드부재(11) 상단부를 밀착함으로써, 2중으로 밀폐가 이루어져 방수 효과를 높이도록 한 것이다. 이때 수밀고무부재의 몸체 역시 수분과 접촉되면 팽창되고 수밀고무부재는 팽창된 상태를 계속 유지하게 된다.When the watertight rubber member 20 installed as described above is in contact with rainwater or water in rainy weather, the watertight rubber member 20 is fitted to the guide member and the flange 21 is expanded to be in close contact with the inside of the guide member 11. At this time, the flange 21 is formed in a hollow shape so that the balloon is inflated when it comes in contact with water to be in close contact with the inner surface of the guide member 11 to be waterproof, and the auxiliary wing 22 is also expanded for moisture. By closely contacting the upper end of the member 11, double sealing is performed to increase the waterproof effect. At this time, the body of the watertight rubber member is also in contact with the water is expanded and the watertight rubber member is kept in an expanded state.

따라서 본 발명은 가이드부재(11)에 설치되는 수밀 고무부재(20)가 플랜지(21)와 보조날개(22)로 구성된 2중 구조로 이루어져 수분과 접촉시 팽창되므로 방수 역시 2중 구조를 갖게 됨으로 교량 이음부에 유입되는 물을 완전하게 차단할 수 있게 된다. Therefore, in the present invention, the watertight rubber member 20 installed on the guide member 11 has a double structure composed of a flange 21 and an auxiliary wing 22, and thus expands upon contact with water, thereby having a double structure of waterproofing. The water flowing into the bridge joint can be completely blocked.

도 8은 본 발명의 교량 이음부재에 배수부재가 설치된 상태를 나타낸 일부 단면도로서, 교량이음부를 수밀고무부재로 완벽하게 차단한다 하더라도 이음부의 양측부로 유입되는 물은 완전하게 차단할 수 없게 되므로 배수부재(30)를 이음부 양측에 설치하여 양측에서 유입되는 물과 수밀고무부재(20) 상부로 유입된 물을 배수부재(30)를 통하여 교각에 설치된 배수관을 통하여 배출시킬 수 있도록 한다.8 is a partial cross-sectional view showing a state in which the drain member is installed in the bridge joint member of the present invention, even if the bridge is completely blocked by the watertight rubber member, the water flowing into both sides of the joint can not completely block the drain member 30 is installed on both sides of the joint to allow the water introduced from both sides and the water flowing into the watertight rubber member 20 to be discharged through the drain pipe installed in the piers through the drain member 30.

즉, 우천시 이음부로 유입된 물은 수밀고무부재(20) 상부로 유입되게 되고 수밀고무부재는 물과 접촉되는 동시에 팽창되어 유입된 물이 다시 하부로 유입되지 못하도록 한다. 수밀고무부재 상부에 유입된 물은 중앙부에 형성된 배수홈(23)을 따라서 이음부 양측으로 이동되고 이동된 물은 배수부재(30)의 배출공(32)을 통하여 배수관으로 배출된다. In other words, the water flowing into the joint portion during rainy weather is introduced into the upper portion of the watertight rubber member 20, and the watertight rubber member is in contact with the water and expands to prevent the introduced water from flowing back into the lower portion. Water introduced into the upper portion of the watertight rubber member is moved to both sides of the joint along the drain groove 23 formed in the central portion, and the moved water is discharged into the drain pipe through the discharge hole 32 of the drain member 30.

상기와 같이 이루어진 본 발명은 교량의 이음부에 수팽창고무부재를 설치하여 빗물이 유입되는 것을 완전히 방수되도록 하고, 교량 이음부재(10)를 강재로 사용하여 내구성을 증대시키고 차량통과시 소음이 감소되도록 하며, 수팽창고무를 사용하여 이음부분과 간격재 부분을 완전하게 팽창밀착시켜 수밀이 유지도록하여 완벽한 방수를 실현할 수 있도록 한 것이다. The present invention made as described above is to install a water-expandable rubber member in the joint of the bridge to completely prevent the rain water flows, to increase the durability by using the bridge joint member 10 as a steel material and to reduce the noise when passing the vehicle By using water-expandable rubber, the joint part and the spacer part are completely expanded and adhered so that watertightness can be maintained to realize perfect waterproofing.

이와 같이 본 발명은 교량 이음부에 수팽창고무로 이루어진 수밀고무부재를 설치하여 방수함으로써 교량의 이음부와 교각, 교좌등이 습기에 의해 부식 및 백태가 발생하는 것을 방지하고 특히 겨울철에 이음부와 교좌가 동결되어 인장력과 하 중에 대한 신축력을 잃어 피로 발생에 따른 교량의 수명이 단축을 방지하는 동시에 견고성과 내구성을 증강시켜 빈번한 보수로 인한 인력과 보수비용을 줄일 수 있도록 된 효과를 갖는다. As described above, the present invention prevents corrosion and whitening of the joints, bridges, bridges, etc. due to moisture by installing a watertight rubber member made of water-expanded rubber at the bridge joint. As the bridge is frozen, the tensile strength and the elasticity of the load are lost, preventing the shortening of the bridge's life due to fatigue and increasing the robustness and durability, thereby reducing the manpower and the maintenance cost due to frequent maintenance.
