Description

Continuous bridge using multiple stage displacement and taper member PSC slab girder connected by member rigid connection portions and method for constructing the same}

본 발명은 직선단면으로 설치되어 발생하는 거더의 형고증가로 인한 건축한계의 문제, 미관저하 및 거더에 작용하는 부재력의 재분배가 비효율적으로 대응되는 단면의 구성을 해소하기 위하여 거더의 변단면구성 및 연속교 구현과 상기 거더를 용이하게 시공하면서 동시에 경제적인 단면이 되는 변단면PSC슬래브거더를 별도로 제작한 후에 이를 교대 및 교각에 설치한다.The present invention is to solve the problem of the construction limit due to the increase in the shape of the girder caused by the linear cross section, the beauty of deterioration and the redistribution of the member force acting on the girder, in order to solve the configuration of the cross section of the girder inefficient and corresponding The construction of the bridge and the girder can be easily constructed, and at the same time, the side cross-section PSC slab girder, which is an economical cross section, is separately manufactured and then installed in the shift and the piers.

상기 지점부상에 설치된 거더와의 사이의 공간부에 부재강결장치를 이용하여 부재강결연결부를 설치하여 연속구조화하고, 지점부상에서는 거더의 지지방식을 종전의 2점지지 방식에서 1점지지 방식으로 교체하거나, 교각 또는 교대를 거더와 강결연결하여 완전한 연속보 구조로 전환시키도록 한다.In the space between the girder and the girder installed on the point portion, by using the member tightening device, the member tightening connection part is installed and structured continuously. On the point portion, the supporting method of the girder is one point supporting method from the conventional two point supporting method. Replace or rigidly connect the pier or alternator with the girder to convert it into a complete continuous beam structure.

상기와 같이 지지방식을 변경하면서 거더를 강결연결하여 설치된 연속교에서는 모멘트의 재분배가 효과적으로 이루어지게됨에 따라 지점부에 설치되는 거더에 작용하는 하중의 크기에 따라 거더를 변단면으로 제작하고, 상기 변단면으로 설치된 연속교에 2차 연속강선 및 지점부 보강 강선등을 다단으로 설치하여 긴장한 후에 정착하여 외력에 상쇄토록 하되, 상기 설치된 2차 연속 강선 및 유지관리를 위한 강선을 거더 내부의 중공부에 설치한 것으로서, 다단으로 설치된 PS강선과 부재강결연결부로 강결연결한 변단면PSC슬래브거더를 이용한 연속교의 시공방법에 관한 것이다.In the continuous bridge installed by rigidly connecting the girder while changing the support method as described above, the redistribution of the moment is effectively made, according to the magnitude of the load acting on the girder installed in the point portion to manufacture the girder as the side cross section, Secondary continuous steel and branch reinforcement steel etc. are installed in multi-stage in the cross-section of continuous bridge, and after tension, it is settled to offset the external force, but the second continuous steel and the steel wire for maintenance are installed in the hollow inside the girder. The present invention relates to a method of constructing a continuous bridge using a PSCS slab girder and a cross-section which is rigidly connected by a multi-stage PS steel wire and a member steel connection part.

종래의 PSC거더교나 프리플렉스거더교인 경우, 제작장에서 제작된 프리캐스트 거더를 교대와 교각, 교각과 교각에 거치한 다음, 상기 거더 상부측에 철근콘크리트 바닥판을 타설 강결한 합성형교이고, 교각에는 상기 거더의 각각에 교좌 장치를 배치 지지하는 단순 구조형식의 한계를 갖게 되며, 이에 의해 신축이음장치를 각 교각마다 설치하므로서 교량의 내구성, 유지관리 및 사용성등에 문제가 발생하게된다.In the case of the conventional PSC girder bridge or preflex girder bridge, the precast girder manufactured in the manufacturing site is mounted on the alternating bridges, piers, piers and piers, and then the reinforced concrete deck is placed on the upper side of the girders, There is a limit of the simple structure type for supporting the bridge arrangement on each of the girders, thereby causing problems in the durability, maintenance and usability of the bridge by installing the expansion joint for each bridge.

최근에는 상기 문제점을 다소 개선할 수 있도록 교각 지점상의 바닥판에 철근을 연속시키면서, 거더 상호간에만 PS강선을 배치하여 긴장 정착하는 방식으로 하고 있으나, 이러한 방법도 교좌장치의 배치 지지방식이 각각의 거더를 지지하는 방법에서 벗어나지 못할뿐아니라, 연속구조계를 구성치 못하여 단순지지 구조계에 근거를 두고 단순히 바닥판만 연속화되므로서 모든 재하 하중에 대해 모멘트 재분배를 못이루어, 거더단면의 증가와 애매한 합성구조로 인한 공사비 증가, 받침등 부대시설 추가 설치에 의한 유지관리비 증가 및 사용성 저하등의 문제점이 있었다.Recently, while reinforcing bars on the bottom plate on the pier point to improve the problem to some extent, by placing the PS steel wire only to each other girder tension fixing method, such a method also supports the arrangement support method of each girder Not only does it deviate from the supporting method, but also it is not possible to construct the continuous structure system, and based on the simple supporting structure system, only the bottom plate is continuous, so that the moment redistribution cannot be performed for all loads. Due to the increase in construction cost, additional installation facilities such as support, there was a problem such as increased maintenance cost and reduced usability.

이를 개선코져 본 발명자가 특허출원한 발명은 직선 단일 PSC슬래브거더와 거더를 상호 연결하고 슬래브와 슬래브는 루프식 철근이음으로 연결한 연속교를 개발하였으나, 상기 연속교는 직선 동일 단면으로 함에 의한 적용 경간장이 제한되거나, 건축한계에 의해 도로 종단고 상승이 되거나, 부재간 강결 방식이 철근을 중첩하여 루푸 및 트러스를 형성하는 등 시공이 다소 번잡하는 것과 2차강선의 정착구가 설치되는 디베이션 블록이 복부의 외부에 돌출되어 미관이 다소 떨어지고, 별도의 발판을 설치하여 강선 긴장 정착하는 번잡성등의 문제점이 있었다.The inventors have applied for a patent application to develop a continuous bridge connecting a single straight PSC slab girder and a girder and connecting the slab and the slab with a looped reinforcing bar, but the continuous bridge has a straight cross section. The construction is somewhat complicated, such as limiting the span length, rising of the road height due to building limits, or the rigidity method between members overlapping reinforcing bars to form loops and trusses, and the reversing block where the secondary steel anchorage is installed. Protruding to the outside of the abdomen, the appearance of a little fell, there was a problem such as the complexity of the line tension settled by installing a separate footrest.

본 발명은 상기와 같은 문제점을 개선하기 위하여 어떤 경간장이나 형하고에 적용 가능하도록 지점부에 다중의 원곡선과 포물선이 결합된 복합곡선에 의한 변단면을 구성하고, 상기 변단면의 형상이 모든 경간에 적용되도록 다중원곡선을 일정하게 하면서 상기 변단면의 복합곡선중 포물선으로 조정이 가능하도록 한 변단면을 구성되도록 하여, 상기 변단면 설치시 적용되는 거푸집의 전용성을 높이는 것과, 2차강선을 정착하는 디베이션 블록을 거더복부 외부에 설치하지 않고, 거더내부에 설치되도록 하기 위하여 거더지점부의 복부 단면의 중앙을 중공화하고, 상기 중공부를 구성하는 격벽에 2차 강선 및 유지관리용 강선을 정착하거나 별도의 디베이션 블록을 설치하여 정착하도록 한다.The present invention constitutes a cross section by a compound curve combined with multiple curves and parabola in the point portion so as to be applicable to any span length and form to improve the above problems, the shape of the cross section is all spans The cross section is made to be adjusted to be a parabola of the complex curve of the cross section while the multi-curve is uniformly applied to increase the exclusiveness of the formwork applied when the cross section is installed, and the secondary steel line is settled. In order to be installed inside the girder without installing the reversing block to the outside of the girder, the center of the abdominal cross section of the girder point portion is hollowed out, and the secondary steel wire and the maintenance steel wire are fixed to the partition wall constituting the hollow portion. Install a separate reversing block to fix it.
