SUPERSTRUCTURE OF T-GIRDER BRIDGE
PROBLEM TO BE SOLVED: To provide a superstructure of a T-girder bridge that not only reduces a number of expensive bearing devices, but also eliminates a location that cannot be inspected after bridge completion and reduces construction costs.SOLUTION: A superstructure 1 of a bridge is spanned between substructures A of the bridge with a bearing device S1 in between. A plurality of transverse beams 2 having a flange 21 extending on one or both sides in a bridge axis direction is mounted on the substructure A with the bearing device S1 in between, the transverse beam having a bridge width direction set as the longitudinal direction thereof. A plurality of precast concrete T-girders 3 having a T-shaped cross-section is spanned between opposite flanges 21, 21' (flanges 22', 21) of the adjacent transverse beams 2, in the bridge width direction leaving a prescribed interval, the T-girder having the bridge axis direction set as the longitudinal direction thereof. The T-girders 3 are fastened horizontally to each other by a PC steel material piercing through the t-girder in the bridge width direction, and applied with pre-stress.SELECTED DRAWING: Figure 1
【課題】高価な支承装置の数を低減することができるだけでなく、橋の完成後に点検できなくなる箇所がなく、且つ、施工費を低減することができるＴ桁橋の上部構造を提供する。【解決手段】橋の下部構造Ａ間に支承装置Ｓ１を介して架け渡された橋の上部構造１であって、橋軸方向の一方又は両方に張り出したフランジ２１を有する複数の横梁２が、橋幅方向を長手方向として下部構造Ａ上に支承装置Ｓ１を介して載置され、断面Ｔ字状のプレキャストコンクリート製の複数のＴ桁３が、橋軸方向を長手方向として橋幅方向に一定間隔を置いて、隣接する横梁２の対向するフランジ２１，２１’（フランジ２２’，２１）間に架け渡されており、Ｔ桁３同士は、Ｔ桁を橋幅方向に貫通するＰＣ鋼材により横締めされてプレストレスが負荷されている。【選択図】図１
