프리캐스트 콘크리트 교량바닥판(1)을 주형(2)의 상부에 부설할 때, 프리캐스트 콘크리트 교량바닥판(1)과 주형(2)간의 충격완화 및 프리캐스트 콘크리트 교량바닥판(1)의 높이조절 등을 위하여 프리캐스트 콘크리트 교량바닥판(1)과 주형(2)사이에는 약간의 틈새를 두는 것이 바람직하며, 이 틈새는 우수 등의 침투로 인한 부식 등을 방지하기 위하여 충진재를 이용하여 틈새를 충진하여야 한다.When laying the precast concrete bridge deck 1 on the upper part of the mold 2, the impact relief between the precast concrete bridge deck 1 and the mold 2 and the height of the precast concrete bridge deck 1 It is preferable to leave a small gap between the precast concrete bridge deck (1) and the mold (2) for the purpose of adjustment, and the gap is formed by using a filler to prevent corrosion due to penetration of rainwater. It should be filled.

도2a는 본 발명에 따른 프리캐스트 콘크리트 교량바닥판과 주형의 이음부 구조도이고, 도2b는 본 발명의 채움재누출방지용 테이프를 나타내는 도면이며, 도2c는 본 발명의 간격재를 나타내는 도면이다.Figure 2a is a structural diagram of the joint of the precast concrete bridge deck and the mold according to the present invention, Figure 2b is a view showing the filling material leakage prevention tape of the present invention, Figure 2c is a view showing the spacer of the present invention.

도면을 참조하여 본 발명에 따른 시공방법을 살펴보면 다음과 같다.Looking at the construction method according to the invention with reference to the drawings as follows.

종래와 같이 주형(2)이 설치된 상태에서 본 발명에서는 교량바닥판(1)을 상기 주형 상부에 설치하기 전에 간격재(5)를 일정한 간격으로 설치하고, 채움재의 충진시 누출을 방지하기 위한 채움재누출방지용 테이프(4)를 주형(2) 상부에 설치한 다음, 교량바닥판(1)을 주형 상부에 형성된 전단연결재(3)를 이용해 부착한다. 그런 다음, 채움재를 전단포켓을 통해 부어넣어 틈새를 충진한다.In the present invention in the state in which the mold 2 is installed as in the prior art, the spacer 5 is installed at regular intervals before the bridge bottom plate 1 is installed in the upper portion of the mold, and a filler for preventing leakage during filling of the filler. The leakage preventing tape 4 is installed on the mold 2, and then the bridge bottom plate 1 is attached using the shear connector 3 formed on the mold. The filler is then poured through the shear pocket to fill the gap.

여기서, 주형(2) 상부에 부설되는 프리캐스트 콘크리트 교량바닥판(1)과 주형(2) 사이에 간격재(5)를 미리 설치하게 되면 프리캐스트 콘크리트 교량바닥판(1)의 무게로 인한 채움재누출방지용 테이프(4)의 압착을 방지하면서 프리캐스트 콘크리트 교량바닥판(1)의 수평이동이 허용되면서 소정의 틈새도 얻을 수 있다.Here, when the spacer 5 is pre-installed between the precast concrete bridge deck 1 and the mold 2, which is placed on the mold 2, the filling material due to the weight of the precast concrete bridge deck 1 A predetermined clearance can be obtained while allowing horizontal movement of the precast concrete bridge deck 1 while preventing the compression of the leak-proof tape 4.

채움재누출방지용테이프(4)는 프리캐스트 콘크리트 교량바닥판(1)과 주형(2)간 채움재의 누출을 방지하기 위하여 압축성이 양호한 발포성고무재질로 제조된 것으로, 주형(2)과 채움재누출방지용 테이프(4)와의 부착을 쉽게하기 위하여 일면에 접착제 처리를 하였고, 현장에서는 접착제보호용비닐(7)를 제거하여 쉽게 부착할 수 있도록 하였다.Filling material leakage preventing tape (4) is made of a foamable rubber material with good compressibility in order to prevent the leakage of the filling material between the precast concrete bridge deck (1) and the mold (2), mold (2) and filling material leakage prevention tape In order to easily attach with (4), an adhesive treatment was applied to one surface, and in the field, the adhesive protection vinyl (7) was removed so that it could be easily attached.

간격재(5)는 채움재와의 일체화를 위하여 시멘트 모르터로 제작된 것이다. 이때 간격재(5)가 유지해야 되는 높이는 아래의 수학식 1과 같은 조건을 만족해야 한다.Spacer 5 is made of cement mortar for the integration with the filling material. At this time, the height that the spacer 5 should maintain must satisfy the condition as shown in Equation 1 below.

Δcom< Hspacer Δ com <H spacer

여기서, Δcom 은 채움재누출방지용 테이프(4)가 프리캐스트 콘크리트 교량바닥판(1) 무게에 의한 압착시 높이(cm)를 나타내고, Hspacer 는 프리캐스트 콘크리트 교량바닥판(1)과 주형(2)사이의 간격재 높이(cm)를 나타낸다.here, Δ com Represents the height (cm) when the filling material leakage prevention tape (4) is crimped by the weight of the precast concrete bridge deck (1), H spacer Denotes the spacer height (cm) between the precast concrete bridge deck 1 and the mold 2.

즉, 간격재의 높이는 채움재누출방지용 테이프(4)의 압착 높이보다는 높게 하여 높이 조절 및 수평이동이 허용되도록 한다.That is, the height of the spacer is higher than the compression height of the filling material leakage preventing tape 4 to allow height adjustment and horizontal movement.

한편, 채움재는 시멘트와 잔골재(모래)가 미리 혼합되어 있는 상태로서, 현장에서는 좁은 틈새의 충진을 양호하게 할 수 있도록 유동성을 확보하기 위한 유동화제와 물을 배합한 후, 충진하는 것으로 한다.On the other hand, the filling material is a state in which cement and fine aggregate (sand) are mixed in advance, and in the field, the filling agent is filled with a fluidizing agent for securing fluidity and water so as to improve filling of a narrow gap.

따라서, 본 발명에서는 프리캐스트 콘크리트 교량바닥판(1)과 주형(2)간 틈새(6)가 채움재누출방지용 테이프(4)의 압착에 의해 밀봉되어 채움재의 타설시 누출현상을 방지할 수 있으며, 프리캐스트 콘크리트 교량바닥판(1)의 상부면을 작업공간으로 활용하여 채움재를 전단포켓(6)에 부어넣어서 틈새의 충진이 가능하다. 또한, 프리캐스트 콘크리트 교량바닥판(1)과 주형(2)간 틈새의 높이 유지 및 바닥판의 미끄러짐 허용은 시멘트 모르터 재질의 간격재(5)로 해결이 가능하다.Therefore, in the present invention, the gap 6 between the precast concrete bridge deck 1 and the mold 2 is sealed by the compression of the filling material leakage preventing tape 4, thereby preventing leakage during pouring of the filling material. The filling of the gap is possible by pouring the filler into the shear pocket 6 by using the upper surface of the precast concrete bridge deck 1 as a working space. In addition, maintaining the height of the gap between the precast concrete bridge deck 1 and the mold 2 and allowing the slip of the bottom plate can be solved by the spacer 5 of cement mortar material.

따라서, 상기와 같이 이루어지는 본 발명에 의하여 프리캐스트 콘크리트 교량바닥판과 주형간의 좁은 틈새를 채움재로 충진할 때, 확실한 밀봉성을 보장하며, 또한 바닥판과 바닥판의 소정의 간격 유지를 위해 바닥판을 조여줄 때 프리캐스트 바닥판과 채움재누출방지용 테이프사이에 미끄러짐이 허용되어 다시 원위치로 복원되지 않아 소정의 목적을 달성할 수 있다. 또한, 교량하부작업대의 설치가 필요없어 해상이나 산악지역과 같이 하부작업대의 설치가 곤란한 경우에는 작업원의 안전사고방지, 공기단축 및 공사비 절감을 이룰 수 있는 효과가 있다.Therefore, when filling the narrow gap between the precast concrete bridge deck and the mold by the filling material according to the present invention made as described above, it ensures a reliable sealing, and also to maintain a predetermined gap between the bottom plate and the bottom plate Slip is allowed between the precast bottom plate and the filling material leakage preventing tape when tightening, so that it is not restored to its original position, thereby achieving a predetermined purpose. In addition, when it is difficult to install the lower work platform such as a sea or mountain area because it is not necessary to install the bridge lower work platform, there is an effect that can prevent safety accidents, reduce air, and reduce construction cost of workers.
