강-콘크리트 인티그럴 복합라멘교의 전단연결재 설치구조{Structure for Installing Shear connector of steel concrete Rahmen type complex integral bridge }Structure for Installing Shear connector of steel concrete Rahmen type complex integral bridge}

본 발명은 교량의 교대와 강재주형간의 강접력을 높여주기위한 전단연결재에 관한 것으로, 더욱 상세하게는 교대와 강결되는 강재주형의 상.하부에 지그재그상의 전단연결재를 보강 설치하므로써, 교대 콘크리트와 강재주형간의 부착 면적을 증가시킴과 동시에 상.하부 구조를 일체 결합시킴으로, 구조적으로 가장 취약할 수 있는 응력 집중부를 보강 처리할 수 있는 강-콘크리트 인티그럴 복합라멘교의 전단연결재에 관한 것이다.The present invention relates to a shear connector for increasing the rigidity between the bridge and the steel mold of the bridge, more specifically, by strengthening the zigzag shear connector in the upper and lower parts of the steel mold to be alternating with the alternating steel, alternating concrete and steel The present invention relates to a shear connector of steel-concrete integrated composite ramen bridge that can reinforce the stress concentration that may be most structurally weak by increasing the attachment area between molds and simultaneously combining upper and lower structures.

라멘(Rahmen) 구조는 부재를 강접(Moment connection)하여 횡력에 저항하게 하는 구조방식이다.Ramen (Rahmen) structure is a structural method that resists the lateral force by connecting the members (Moment).

여기서, 라멘교(Rahmen Bridge)란 교량의 상부구조와 하부구조를 강절로 연결함으로써 전체구조의 강성을 높임과 동시에 지간내에 발생하는 휨모멘트의 크기 를 줄이는 대신 이를 교대나 교각이 부담하게 하는 교량으로,Here, the Ramen Bridge is a bridge that increases the stiffness of the entire structure by connecting the upper and lower structures of the bridge with a steel beam, and at the same time reduces the magnitude of the bending moment occurring in the area, instead of burdening the bridge or the bridge. ,

50m 지간까지 신축이음(Expansion Joint) 이나 교량받침이 없이 가설이 가능하고, 유지 관리면에서 같은 지간의 단순교에 비해 유리하며 주형의 두께가 상대적으로 작게 설계될수 있어 교량의 미관이 수려하며, 특히 중앙부로부터 지간의 양단으로 헌치 형태를 이룰 경우 더욱 날렵한 모양을 이룬다.It can be hypothesized without expansion joints or bridge bearings up to 50m, and it is advantageous compared to simple bridges in the same area in terms of maintenance, and the thickness of the mold can be designed relatively small, so the beauty of the bridge is beautiful. The haunting form from the center to the ends of the span is more slender.

또한, 라멘교는 교각의 높이가 그리 높지 않고 단경간의 교량에서 사용 하는 것이 경제적인 것이며, 우리나라의 경우 고속도로 횡단교량에서 많이 볼 수 있는 것으로, 매우 다양한 형태의 설계가 가능하며, 보의 두께를 작게 하여 가늘게 보이도록 하는 것이 보통이므로 교대나 교각의 두께가 상대적으로 두껍다.In addition, the Ramen Bridge is economical to use in bridges with short spans without high heights, and in Korea, it can be seen in highway cross-section bridges. In general, the thickness of the alternating or pier is relatively thick.

한편, 상기와 같은 종래 라멘교의 강재주형과 상.하부 구조를 강접하는 구조는, 교대의 상부에 횡방향으로 다수의 수직형 지지형강이 돌출 형성되어 하부구조가 형성되며, 상기 각각의 지지형강에는 직교방향 즉, 종방향으로 교대간을 연결하는 I형강으로 된 강재주형이 설치되며, 상기 지지형강과 강재주형 간에 횡방향 철근이 배근됨으로 강접부가 형성되는 것이며, 상기 강접부에는 콘크리트가 타설되어 상부구조가 형성되는 것이다.On the other hand, in the structure of the steel mold and the upper and lower structures of the conventional ramen bridge as described above, a plurality of vertical support steel is protruded in the transverse direction formed on the upper portion of the shift to form a lower structure, each of the supporting steel Steel molds are formed of I-shaped steel that connects alternately in the orthogonal direction, that is, longitudinally, and steel joints are formed by transverse reinforcing bars between the supporting steels and the steel molds, and concrete is poured on the steel joints. The structure is formed.

그러나, 상기와 같은 종래의 강접구조는, 지지형강과 강재주형의 연결 및 철근배근의 공정이 현장에서 이루어지므로, 현장 시공 공정상의 난해함을 가져오는 문제점이 발생하였다.However, in the conventional steel joint structure as described above, the connection between the support steel and the steel mold and the step of the reinforcement is made in the field, there is a problem that causes difficulties in the field construction process.

또한, I형강과 하부구조의 연결은 단순 지지형강으로 이루어지고, 상부구조 강접부는 단순 지지형강과 강재주형 및 횡방향 철근으로만 이루어지므로, 교대와 하부구조간의 부착면적이 적어 강접력이 현저히 감소하며, 상부구조 콘크리트 타설시 강재주형과 콘크리트간의 강접력 또한 현저히 감소하는 문제점이 발생하였으며, 이로인한, 상.하부 구조의 강접력 저하로 구조적으로 가장 취약할 수 있는 응력 집중부의 보강에 취약한 문제점이 발생하였다.In addition, the connection between the I-beam and the substructure is made of simple supporting steel, and the superstructure steel joint is composed of only the simple supporting steel, steel mold and transverse rebar, so that the rigidity of the steel is significantly reduced due to the small attachment area between the shift and the substructure. In addition, there was a problem that the steel contact between the steel mold and the concrete was significantly reduced when the upper structure concrete was placed.Therefore, the weakness of the reinforcement of the stress concentrator, which is structurally the most vulnerable due to the lowered strength of the upper and lower structures, Occurred.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 다수의 강재주형이 교량의 교대에 매설되는 구조를 가지며, 강재주형의 상.하부면에 지그재그상의 전단연결재를 부착 형성하므로써, 교대와 강재주형 및 하부구조와 상부구조간의 강접 면적을 현저히 상승시킬 수 있는 강-콘크리트 인티그럴 복합라멘교의 전단연결재 설치구조를 제공함에 본 발명의 목적이 있는 것이다.The present invention has been made to solve the above problems, and has a structure in which a plurality of steel molds are embedded in the alternating bridge, by forming a zigzag shear connector attached to the upper and lower surfaces of the steel mold, alternating and steel It is an object of the present invention to provide a shear connector installation structure of a steel-concrete integral composite ramen bridge that can significantly increase the rigid contact area between the mold and the substructure and the superstructure.

상기와 같은 목적을 달성하기 위한 구체적인 수단으로는, 상.하부에 상.하부플랜지가 형성되어 일정거리를 두고 시공되는 교대와 교대를 연결하되, 상부플랜지면이 각각의 교대 상부면에 노출되게 양측이 각각의 교대에 매입 설치되는 "I형"상의 강재주형과; As a specific means for achieving the above object, the upper and lower flanges are formed on the upper and lower sides to connect the shifts and the shifts are constructed at a certain distance, the upper flange surface is exposed on both sides of the upper surface of each shift A steel mold of " I type " embedded in each of these shifts;

상기 강재주형의 상.하부플랜지부의 양측 매설부에 형성되며, 다수의 종형판과 다수의 횡형판이 지그재그상으로 연속되게 연결 형성된 전단연결재와; A shear connection member formed on both buried portions of the upper and lower flange portions of the steel mold, and the plurality of longitudinal plates and the plurality of horizontal plates are continuously connected in a zigzag shape;

상기 전단연결재의 종형판에 관통 배근되는 다수의 주철근과; 및A plurality of cast irons penetrating through the longitudinal plate of the shear connector; And

상기 전단연결재의 각각의 횡형판을 관통 연결 배근되는 배력철근으로 구성함으로 달성할 수 있는 것이다.It can be achieved by configuring each of the transverse plate of the shear connection member consisting of the reinforcement bar is reinforced through the bar.

상기와 같이 본 발명 강-콘크리트 인티그럴 복합라멘교의 전단연결재 설치구조는, 강재주형의 교대 및 상부구조의 콘크리트 타설부에 지그재그상의 전단연결재를 공장에서 미리 용접시공된 상태에서 현장으로 이동하고, 현장에서는 횡방향의 주철근으로 각열의 전단연결재 연결 및 종방향의 배력철근에 의해 교대와 교대간을 연결 하므로써, 시공공정을 단순화 시켜 현장 시공의 우수성을 가져올 수 있는 효과를 얻을 수 있는 것이다.As described above, the shear connector installation structure of the steel-concrete integral composite ramen bridge of the present invention moves the shear connector on the concrete casting of the alternating steel mold and the superstructure to the site in the state of being welded in advance in the factory, and the site In the lateral direction of the main reinforcing bar connecting the alternating and alternating by connecting the shear connector in each row and the longitudinal reinforcement bar, it is possible to obtain the effect of simplifying the construction process, bringing excellence in the field construction.

또한, 전단연결재가 형성된 강재주형이 교대에 매설되는 구조를 가지므로, 교대와 강재주형간의 부착면적이 증가되어 강접력이 현저히 상승되며, 상부구조 콘크리트 타설시 지그재그상의 전단연결재에 의해 콘크리트와 부착 면적이 현저히 상승되어, 구조적으로 가장 취약할 수 있는 응력 집중부의 보강력을 상승시킬 수 있는 효과를 얻을 수 있는 것이다.In addition, since the steel mold in which the shear connector is formed is embedded in the alternating steel, the adhesion area between the alternating steel mold and the steel mold is increased, and the steel welding force is significantly increased. This remarkably increases, and the effect of raising the reinforcement of the stress concentration portion that may be the structurally weakest can be obtained.
