Description

교량 동바리 시스템{Bridge supporting post system}Bridge supporting post system

본 발명은 교량 동바리 시스템에 관한 것으로, 특히 지반조건에 구애받지 않고 시공할 수 있는 교량 동바리 시스템에 관한 것이다. The present invention relates to a bridge club system, and more particularly, to a bridge club system that can be constructed regardless of the ground conditions.

일반적으로 철근콘크리트 슬래브교 또는 라멘교의 상부슬래브를 시공함에 있어서, 상부슬래브 시공시에 사용하는 지지방법은 다수개의 강관을 상부슬래브 하부의 지반에 설치하여, 상부슬래브의 하중을 지지하는 강관 시스템 동바리 지지방법을 사용하고 있다.In general, in the construction of upper slabs of reinforced concrete slab bridges or ramen bridges, the supporting method used in the construction of upper slabs is to support the steel pipe system copper bar for supporting the load of the upper slab by installing a plurality of steel pipes on the ground under the upper slab. I'm using the method.

이러한 강관 시스템 동바리 지지방법은 강관을 다수 개로 밀집하여 지지하는 구조로 강관 시스템 동바리가 시중에 널리 퍼져 있고, 공사비도 경제적이기 때문에 현재까지도 널리 사용되고 있다. The steel pipe system dongbar support method is a structure that supports a large number of steel pipes in a crowded structure, the steel pipe system dongbari is widely used in the market, and construction costs are also widely used to this day.

교량을 시공하는데 사용되는 종래의 강관 시스템 동바리 공법은 도 1에 도시된 바와 같이 지반다짐을 철저히 하여야 하고, 동바리 설치시에 동바리의 상단부 높이를 모두 일치되게 조정해야 하며, 특히 우기에 하천구역에서는 통수 단면을 감소시켜 우기의 강우시에 동바리의 파손으로 상부슬래브가 붕괴되거나 동바리가 댐 역할을 하여 상류가 침수되는 등의 많은 문제점이 있으며, 또한 상부슬래브 콘크리트 타설 시 동바리 붕괴사고가 자주 일어나 근로자의 사상사고가 빈번하게 발생하고 있다.Conventional steel pipe system dongbari method used to construct the bridge should be ground compaction, as shown in Figure 1, and the height of the top of the dongbari must be adjusted to match all the installation, especially in the rainy season river water flow There are many problems such as the collapse of the upper slab due to the damage of the copper bar during the rainy season and the flooding of the upper slab due to the damage of the upper bar, and the flooding of the upper slab during the concrete slab. Accidents occur frequently.

이렇나 강관 시스템의 동바리 구조가 많은 단점이 있음에도 계속 사용되는 이유는 철근콘크리트 슬래브교 또는 라멘교가 다른 교량형식에 비해 경제성이 워낙 뛰어나 널리 적용되기 때문이기도 하다.The reason why the copper bar system has many shortcomings is that it is still used because reinforced concrete slab bridges or ramen bridges are more economical and widely applicable than other bridge types.

반면에 지반조건이 연약지반이거나 지장물이 많거나 하여 강관 시스템 동바리를 사용할 수 없는 경우에는 경제적인 철근콘크리트 슬래브교나 라멘교를 적용하지 못하고 공사비가 매우 고가인 강합성 라멘교 등을 적용함에 따라 많은 예산이 낭비되고 있는 실정이다.On the other hand, when the ground condition is soft ground or there are many obstacles, the steel pipe system copper bar cannot be used. Therefore, economical reinforced concrete slab bridges or ramen bridges cannot be applied. The budget is wasted.

즉, 종래의 철근콘크리트 슬래브교나 라멘교의 상부슬래브를 시공함에 있어서 널리 사용되는 상부슬래브 지지시스템의 하나인 강관시스템 동바리 공법은 공사비가 매우 경제적인 장점은 있지만 설치과정이 매우 복잡하고 통수 단면을 감소시키며, 지반이 연약지반이거나 다짐이 불량하거나 동바리 설치에 약간의 하자가 있어도 대부분 붕괴사고로 연결되어 많은 단점이 있다.In other words, the steel pipe system dongbari method, which is one of the upper slab support systems widely used in the construction of the upper slab of the reinforced concrete slab bridge or the ramen bridge, has a very economical cost, but the installation process is very complicated and reduces the cross section. However, even if the ground is soft ground or poor compaction or some defects in the installation of the club, most of them are connected to collapse accidents.

이에, 본 발명은 상기한 제문제점을 해결하기 위해 안출된 것으로, 통수 단면을 전혀 감소시키지 않고, 지반 조건에 구애받지 않으며, 설치가 간편하고 공사비가 저렴한 교량 동바리 시스템을 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned problems, it is an object of the present invention to provide a bridge system without any reduction in the cross-sectional area, irrespective of the ground conditions, easy installation and low construction cost.

상기한 목적을 달성하기 위한 본 발명에 따른 교량 동바리 시스템은 교량의 상부슬래브를 지지하는 동바리 구조에 있어서, 교각에서는 교각 상단부의 전, 후면에 강재받침이 부착되고, 상기 강재받침은 PS강재에 의해 상호 결속되고, 교대에서는 교대 상단부의 내측면에 강재받침이 부착되고, 배면에 강판이 부착되며, 상기 강재받침과 강판이 PS강재에 의해 상호 결속됨을 특징으로 한다.Bridge dongbar system according to the present invention for achieving the above object in the dongbar structure for supporting the upper slab of the bridge, in the pier the steel bearings are attached to the front and rear of the upper end of the bridge, the steel bearing is made of PS steel It is characterized in that the mutual binding, the steel support is attached to the inner surface of the upper end portion of the shift, the steel plate is attached to the back, the steel support and the steel plate is characterized in that the mutual binding by the PS steel.

이상에서 설명한 바와 같이, 본 발명에 따른 교량 동바리 시스템은 다음과 같은 효과가 있다.As described above, the bridge club system according to the present invention has the following effects.

첫째, 본 발명은 연약지반이거나 하부에 지장물이 존재하거나 교통을 소통시켜야 하는 등 어떠한 하부조건 하에서도 상부슬래브의 시공이 가능하여 예산을 절감할 수 있는 이점이 있다.First, the present invention has the advantage that the construction of the upper slab under any lower conditions, such as the presence of obstacles in the soft ground, or to communicate with the lower traffic can be reduced budget.

둘째, 본 발명은 강재받침을 PS강재에 의해 상호 결합하고, 지지대를 사용함으로써 동바리의 안전성이 대폭 증대되어 시공중 붕괴사고를 방지할 수 있는 이점이 있다.Second, the present invention has the advantage that can be prevented from collapsing accident during construction by combining the steel support with the PS steel, using a support, greatly increases the safety of the copper bar.

셋째, 본 발명은 동바리 설치가 간편하고, 자재를 반복하여 사용할 수 있으므로 공사비를 절감할 수 있는 이점이 있다.Third, the present invention has the advantage that can be easily installed, and the construction cost can be reduced because the material can be used repeatedly.

넷째, 본 발명은 통수 단면을 감소시키지 않으므로 우기시에도 슬래브 공사를 원활하게 시공할 수 있는 이점이 있다.Fourth, the present invention does not reduce the cross section of the water flow, there is an advantage that can be smoothly constructed slab construction even during the rainy season.
