PRECAST PEDESTRIAN CROSSOVER BRIDGE AND THE CONSTRUCTION METHOD THEREFOR
The present invention relates to a PC pedestrian overpass having excellent section stiffness and constructability and a construction method thereof as a precast concrete pedestrian overpass. The PC pedestrian overpass comprises: a lower object in the form of a rectangular object, in a beam shaped to be curved upwards, and whose sectional height increases from both ends to the center; a web formed of a vertical member having a width (w2) smaller than the width (w1) of the lower object, and formed in the same width and sectional height in the extension direction of the lower object; an extension upper flange horizontally extended in both lateral directions from the upper part of the web, and serving as a bottom plate; and both inclined lateral plates which is a plate member inclined downwards from the end of the both extension upper flanges to the upper edge of the lower object. Moreover, a hollow part (S1) is formed in both lateral sides of the web by the extension upper flange, both inclined lateral plates, and the lower object.
프리캐스트 콘크리트 보도육교에 있어, 단면강성이 우수하면 시공성이 뛰어난 PC보도육교 및 그 시공방법에 관한 것으로서, 상기 PC보도육교는 사각구체로 형성되도록 하되 양 단부로부터 중앙부로 갈수록 단면높이가 커지는 상방 만곡된 형태로 형성된 빔 형태의 하부구체; 상기 하부구체 폭(w1) 보다 작은 폭(w2)을 가진 수직부재로 형성되며 하부구체 연장길이방향으로 동일한 폭과 단면높이로 형성된 복부; 상기 복부 상부로부터 양 측방으로 수평 연장되어 바닥판 역할을 하는 확장상부플랜지 확장상부플랜지; 및 상기 양 확장상부플랜지 단부로부터 하부구체의 상부 모서리로 하방 경사져 형성된 플레이트부재인 양 경사측판;을 포함하여, 상기 확장상부플랜지, 양 경사측판 및 하부구체에 의하여 복부 양 측방으로 중공부(S1)가 형성된다.
