Description

상하부 일체형 백본 아웃리거 구조를 갖는 도시친화형 고가구조물Urban-friendly elevated structure with integrated top and bottom backbone outrigger structure
본 발명은 상하부 일체형 백본 아웃리거 구조를 갖는 도시친화형 고가구조물에 관한 것이다. 보다 상세하게는 사람의 척추에서 갈비살이 나와 있는 구조에 착안하여 도출된 구조로서, 고가구조물의 상부구조에 척추역할을 하는 종방향 백본 상부 구조물이 연속적으로 있고 이와 연결된 하부구조(교각)와 일체로된 고가구조물이다.The present invention relates to an urban-friendly elevated structure having an upper and lower integrated backbone outrigger structure. More specifically, it is a structure derived by focusing on the structure in which the ribs protrude from the human spine. The upper structure of the elevated structure has a longitudinal backbone upper structure that serves as a backbone continuously, and is integrated with the lower structure (pier) connected thereto. It is an expensive structure.
교량은 차량이나 보행자의 통행을 위한 상판 및 상판을 지지하는 거더를 포함하여 이루어진다. 이때, 거더는 교량의 길이방향으로 단수 또는 복수 개가 나란하게 배치되어 상판을 지지하게 되며, 거더의 재질은 강재나 콘크리트가 주로 사용되며 경우에 따라 강재와 콘크리트가 조합된 것이 사용되기도 한다.The bridge includes a deck for the passage of vehicles or pedestrians and girders supporting the deck. At this time, one or more girders are arranged side by side in the longitudinal direction of the bridge to support the deck, and steel or concrete is mainly used as the material of the girder, and in some cases, a combination of steel and concrete is used.
한편, 교량의 상판에는 기능성이나 심미성, 또는 안정성 등을 향상시킬 목적으로 난간, 방음벽 등과 같은 각종 구조물이나 조형물이 설치되는 사례가 증대하고 있다. 이러한 구조물이나 조형물 모두는 비구조체로서, 교량에 작용하는 하중을 분담하는 구조체로서 전혀 기능하지 못하고 교량에 하중을 전가시키게 된다. 이로 인해, 교량의 구조적 안정성을 담보하기 위해 시공에 사용되는 거더의 크기가 점점 증대되고 있는데, 이는 시공 자체를 어렵게 하고 비용을 증대시키는 요인으로 작용하고 있다.On the other hand, cases in which various structures or sculptures, such as handrails and soundproof walls, are installed on the deck of bridges for the purpose of improving functionality, aesthetics, or stability are increasing. All of these structures or sculptures are non-structural, and do not function at all as structures that share the load acting on the bridge, and transfer the load to the bridge. For this reason, the size of girders used in construction is gradually increasing to ensure the structural stability of bridges, which makes construction itself difficult and acts as a factor increasing costs.

As shown in FIG. 2, a long-span bridge in which a box girder and a truss girder are combined is known, and as shown in FIG. 3, the shape of the lower structure (pier) is in the longitudinal direction and occupies a lot of road width. A structure that does not do this is described. That is, there is a hybrid bridge girder that fuses a PSC girder, a box girder, and a truss girder in which the girder is formed of steel, steel wire, and concrete for a long-span bridge and a long-span bridge in which the girder is integrally formed with the point of the substructure (pier). .
도 4는 종래기술 4(등록특허 10-1164935)로서, 자전거 통행용 교량의 부분 사시도를 도시한 것이다. 도 4에 도시된 바와 같이, 중앙부에 거더나 데크에서 양쪽으로 통로 형성을 위한 외팔보 형식으로 부착한 교량이 존재함을 알 수 있다. 4 is a partial perspective view of a bridge for bicycle traffic as Prior Art 4 (Registered Patent No. 10-1164935). As shown in FIG. 4, it can be seen that there is a bridge attached in the form of a cantilever for forming a passage on both sides from the girder or deck in the central part.
그러나 종래 공개된 장대교량은 현수교나 사장교 형식의 기초가 되는 주탑을 설치하고 현수나 사장교 형식에 의해 거더를 설치하여 케이블과 연결함에 따라 도시의 미관을 해치고 도로에 주탑을 건설할 경우 많은 면적을 차지하여 토지 이용에 한계가 있다. However, conventionally disclosed long-span bridges install pylons that are the foundation of suspension bridges or cable-stayed bridges, install girders in the form of suspension or cable-stayed bridges, and connect them with cables, thereby damaging the aesthetics of the city and occupying a large area when constructing pylons on roads. Therefore, land use is limited.
또한, 장대 교량을 위한 거더를 설치하지 않고 원통형상의 고가구조물을 이용한 교량에서, 원통형상의 폐합단면 구조물은 원통형상의 고가구조물을 제작하기 위해 튜브 형상의 내벽과 외벽을 일체화하여 고가구조물을 제작하는 것으로 공중에 있는 터널형태로 되어 통행자들에게 터널에서 느끼는 불편감을 주고 무게와 경제적인 면에서도 폐합단면 고가구조물을 교량으로 이용하는데 문제점이 존재하고, 단면이 크거나 길이가 길면 제작이나 이동에 많은 어려움이 존재한다. In addition, in a bridge using a cylindrical elevated structure without installing a girder for a long-span bridge, the cylindrical closed cross-section structure is to manufacture an elevated structure by integrating the inner and outer walls of the tube shape to produce a cylindrical elevated structure. In the form of a tunnel in the tunnel, it gives passengers discomfort felt in the tunnel, and there are problems in using the closed cross-section elevated structure as a bridge in terms of weight and economy. exist.
그리고 트러스 교량은 디스크 형태를 길이방향으로 배치하고 사이를 연결하여 현장에서 제작하는 것이 가능하나 형태가 일정하지 않아 응력집중이 발생할 수 있어 대형교량에 문제점이 있으며, 세로보를 설치하고 후프형태의 부재를 감아 형상을 유지하는 튜브형태로 제작하는 것 또한 응력에 문제가 있어 대형교량에는 적합하지 않은 형태에 해당한다. In addition, truss bridges can be manufactured on site by arranging disk shapes in the longitudinal direction and connecting them, but there is a problem with large bridges because the shape is not constant and stress concentration can occur. It is also not suitable for large bridges because it is produced in a tube form that maintains its shape by winding it.
또한 중앙에 거더를 설치하고 양측에 외팔보를 횡으로 설치하여 통로를 형성한 단선 교량은 존재하나, 장대교량의 하부구조(교각) 사이를 사장교나 현수교가 아닌 교량은 존재하지 않는다. In addition, there are single-line bridges in which a girder is installed in the center and cantilever beams are installed horizontally on both sides to form a passage, but there are no bridges other than cable-stayed bridges or suspension bridges between the substructures (piers) of long-span bridges.
