Continuous bridge closure section connecting structure and construction method thereof
The invention discloses a continuous bridge closure section connecting structure and a construction method thereof.The continuous bridge closure section connecting structure comprises two frame structures, each frame structure comprises flange plates on the two sides corresponding to the end face of a closure section cantilever, and a top plate, webs on the two sides and a bottom plate are integrally formed and correspond to the end face of the cantilever in a matched mode and abut against the end face of the cantilever; first through holes are formed in the junction of a flange plate, a top plate and a web plate of the frame structure and the junction of a bottom plate and the web plate; the multiple main reinforcement structures are arranged between the two frame structures respectively, each main reinforcement structure is composed of a second reinforcement section and a third reinforcement section in a lap joint mode, and the lap joint position of the second reinforcement section and the third reinforcement section has the spatial length for sliding in the length direction; each supporting frame corresponds to each frame structure and is detachably connected with the frame structure; and the telescopic push rod is detachably mounted between the two supporting frames. The method has the effects of tightly jacking and locking the closure section, avoiding deformation and cracking of closure section concrete in the solidification period, improving the connection stability of the closure section and the like.
本发明公开了一种连续桥梁合拢段连接构造及其施工方法，包括两个框架结构，其每个框架结构包括与合拢段悬臂端面对应的两侧翼缘板、顶板、两侧腹板和底板一体成型且与悬臂端面匹配对应并抵接；在框架结构的翼缘板、顶板和腹板交接处、以及底板和腹板交接处设置有第一通孔；多个主筋结构，其分别设置在两个框架结构之间，每个主筋结构包括第二钢筋段与第三钢筋段搭接组成，第二钢筋段与第三钢筋段的搭接处具有沿长度方向滑动的空间长度；两个支撑架，其每个支撑架与每个框架结构对应并可拆卸连接；伸缩推杆，其可拆卸安装在两个支撑架之间。本发明对合拢段具有顶紧锁定效果，避免凝固期的合拢段混凝土变形、开裂，提高合拢段连接的稳定性等效果。
