Slideway type transverse connecting structure suitable for splicing and widening project of long-connected concrete bridge
The invention relates to a slideway type transverse connecting structure suitable for splicing and widening engineering of a long-connected concrete bridge, which is used for splicing and widening of an old bridge and a new bridge and comprises a core sliding block, a plurality of sliding blocks and a plurality of sliding blocks, the longitudinal slide way is positioned on the new bridge side and is in sliding fit with the core slide block along the bridge direction; the transverse embedded steel bars are embedded into the old bridge, and one ends of the transverse embedded steel bars extend out and are fixedly connected with the core sliding block; one end of the transverse connecting steel bar is positioned in the core sliding block in the transverse bridge direction, the other end of the transverse connecting steel bar penetrates through the core sliding block and the longitudinal sliding way, and the transverse connecting steel bar is fixed to the new bridge in a tensioned state. A conventional transverse connection mode is replaced by the method, so that the spliced box girder has the capabilities of longitudinal sliding, vertical shearing resistance and transverse pulling resistance, and a series of problems generated after the concrete continuous girder bridge is spliced and widened under a conventional construction method are effectively solved.
本发明涉及一种适用于长联混凝土桥梁拼接拓宽工程的滑道式横向连接结构，用于旧桥与新桥的拼接拓宽，该滑道式横向连接结构包括：位于旧桥侧的核心滑块；位于新桥侧并沿顺桥向滑动贴合所述核心滑块的纵向滑道；预埋至所述旧桥内且一端伸出并固定连接所述核心滑块的若干横向预埋钢筋；一端沿横桥向定位于所述核心滑块内，另一端穿过所述核心滑块与纵向滑道，并呈张紧状态与所述新桥固定的横向连接钢筋。以本发明来替换常规的横向连接形式，可以使得拼接后的箱梁兼具纵向滑移、竖向抗剪、横向抗拔能力，有效解决常规施工方法下混凝土连续梁桥拼接拓宽后产生的一系列问题。
