Description

콘크리트 엣지블록이 개선된 교량{The bridge where edge block was improved}The bridge where edge block was improved

본 발명은 콘크리트 엣지블록이 개선된 교량에 관한 것으로, 특히 PSC 라멘교 또는 슬래브교의 슬래브 상면 중앙부 또는 양측면 또는 중앙부와 양측면에 추가긴장용 콘크리트 엣지블록 다수 개를 소규모로 대칭 또는 비대칭으로 설치한 콘크리트 엣지블록이 개선된 교량에 관한 것이다.The present invention relates to a bridge with improved concrete edge blocks, and in particular, a concrete edge in which a plurality of concrete edge blocks for additional tension are installed in small centers or both sides of the slab bridges of a PSC ramen bridge or a slab bridge, or a plurality of additional tension edges on both sides. The block relates to an improved bridge.

일반적으로 PSC 라멘교 또는 슬래브교(B)는 슬래브(S) 상면 중앙부(도 1a 참조) 또는 양측면(도 1b 참조) 또는 중앙부와 양측면(도 1c 참조)에 추가 긴장용 콘크리트 엣지블록(E)을 설치함에 있어서, 각 부분당 동일한 크기의 2개의 콘크리트 엣지블록(E)을 설치하여 PC강선(W)의 2차 긴장 또는 유지관리용 긴장인 추가 긴장용으로 사용하고 있어, 추가 PC강선(W)의 긴장의 효율을 확보하기 위한 콘크리트 엣지블록(E)의 규모가 다소 커서, 소규모 교량이 대부분인 PSC 라멘교 또는 슬래브교(B)의 교량 규모에 따른 콘크리트 엣지블록(E)의 조화비율이 맞지 않아 미관이 다소 불리하게 작용하고, 가각부(보행자 통로와 도로의 연결부분)에 있어서는 콘크리트 엣지블록(E)의 크기 때문에 차량의 좌회전 또는 우회전시에는 시거(視距)확보가 어려운 측면이 상존하고 PC강선 정착부(F)의 수량 제한으로 PC강선(W)의 효율을 추가로 증대시키는데 한계가 있었다. In general, the PSC ramen bridge or slab bridge (B) has an additional tension concrete edge block (E) at the center of the slab (S) (see FIG. 1A) or on both sides (see FIG. 1B) or at the center and both sides (see FIG. 1C). In the installation, two concrete edge blocks (E) of the same size are installed for each part and used for additional tension, which is the secondary tension or maintenance tension of the PC steel wire (W), and the additional PC steel wire (W) The size of the concrete edge block (E) is rather large to secure the efficiency of tension, and the proportion of the concrete edge block (E) according to the bridge size of the PSC ramen bridge or the slab bridge (B), which is a small bridge, is not right. The aesthetic appearance works somewhat disadvantageously, and in the corner part (the connection part of the pedestrian passageway and the road), the size of the concrete edge block (E) makes it difficult to secure the cigar when turning left or right of the vehicle. Liner With the yield limit of chakbu (F) there is a limit to augment further the efficiency of the PC steel wire (W).

이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위해 안출된 것으로, PSC 라멘교 또는 슬래브교의 슬래브 상면 중앙부 또는 양측면 또는 중앙부와 양측면에 추가긴장용 콘크리트 엣지블록 다수 개를 소규모로 대칭 또는 비대칭으로 설치함으로써, 교량규모에 따른 콘크리트 엣지블록의 조화비율을 적정하게 유지할 수 있고, 차량의 시거확보를 용이하게 할 수 있으며, PC강선의 효율을 추가로 증대시킬 수 있을 뿐만 아니라 저형고ㆍ장경간화가 가능하도록 한 콘크리트 엣지블록이 개선된 교량을 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the problems described above, a plurality of concrete edge blocks for further tension in the center or both sides of the upper surface of the slab of the PSC ramen bridge or slab bridge or both sides and the symmetrical or asymmetrically small By installing it, it is possible to maintain the harmony ratio of the concrete edge block according to the bridge size, to secure the vehicle's cigars easily, to further increase the efficiency of the PC steel wire, as well as to reduce the height and length of the bridge. The aim is to provide an improved bridge with a concrete edge block made possible.

상기한 목적을 달성하기 위한 본 발명에 따른 콘크리트 엣지블록이 개선된 교량은 PSC 라멘교 또는 슬래브교의 슬래브 상면 중앙부 또는 양측면 또는 중앙부와 양측면에 PC강선 추가긴장용 콘크리트 엣지블록을 설치함에 있어서, 상기 슬래브 상면 중앙부 또는 양측면 또는 중앙부와 양측면의 각 부분에 3개 이상의 콘크리트 엣지블록을 설치하고, 상기 콘크리트 엣지블록 내에 PC강선을 설치하며, 상기 PC강선을 2차 긴장 또는 유지관리 및 긴장용으로 사용함을 특징으로 한다. The improved concrete edge block according to the present invention for achieving the above object is the slab top center portion or both sides or the center or both sides of the slab bridge of the PSC ramen bridge or slab in the installation of the concrete edge block for PC steel wire additional tension, the slab Three or more concrete edge blocks are installed on the upper center part or both sides or each part of the central part and both sides, the PC steel wire is installed in the concrete edge block, and the PC steel wire is used for secondary tension or maintenance and tension. It is done.

이상에서 설명한 바와 같이, 본 발명에 따른 콘크리트 엣지블록이 개선된 교량은 PSC 라멘교 또는 슬래브교의 슬래브 상면 중앙부 또는 양측면 또는 중앙부와 양측면에 추가긴장용 콘크리트 엣지블록 다수 개를 소규모로 대칭 또는 비대칭으로 설치함으로써, 소규모 교량이 거의 대부분인 PSC 라멘교 또는 슬래브교의 교량규모에 따른 콘크리트 엣지블록의 조화비율을 적정하게 유지할 수 있으므로 미관을 증대시킬 수 있고, 가각부의 경우에는 좌회전 또는 우회전시 시거확보를 용이하게 할 수 있으며, PC강선 정착부를 신축적으로 연장할 수 있어, 2차 긴장 또는 유지관리용 긴장인 추가긴장을 다수의 정착구로 자유자재로 구사함으로써, PC강선의 효율을 추가로 증대시킬 수 있어, 저형고ㆍ장경간화를 가능하게 하며, 유지관리에 완벽을 기할 수 있는 효과가 있다.As described above, the bridges with improved concrete edge blocks according to the present invention are installed in the symmetrical or asymmetrical asymmetrical or asymmetrically a small number of additional concrete edge blocks in the middle or both sides of the upper surface of the slab bridge or PSC ramen bridge or slab bridge By doing so, it is possible to properly maintain the harmonic ratio of the concrete edge block according to the bridge size of the PSC ramen bridge or the slab bridge, which is almost the small bridge, so that the aesthetics can be increased. It is possible to extend the PC steel wire fixing unit flexibly, and by using the additional tension, which is the secondary tension or maintenance tension freely, can increase the efficiency of the PC steel wire further, Efficient for long sentence and long span and perfect for maintenance A.
