New and old bridge splicing structure for bridge widening and construction method thereof
The invention provides a new and old bridge splicing structure for bridge widening and a construction method thereof, and belongs to the technical field of bridge engineering. A new bridge and an old bridge are connected through an I-shaped section beam, the I-shaped section beam comprises an upper wing plate, a web plate and a lower wing plate, the upper wing plate and the lower wing plate are arranged in a spaced mode, and the web plate is connected with the upper wing plate and the lower wing plate; the two sides of the upper wing plate are in lap joint with the upper portion of the old bridge edge beam wing plate and the upper portion of the new bridge edge beam wing plate respectively, and the two sides of the lower wing plate abut against the lower portion of the old bridge edge beam wing plate and the lower portion of the new bridge edge beam wing plate respectively and are supported on the old bridge edge beam web and the new bridge edge beam web through the beam supports. The spring supports are clamped between the beam support and the old bridge edge beam web and between the beam support and the new bridge edge beam web, and the webs are clamped between the old bridge edge beam wing plate and the new bridge edge beam wing plate. The deformation resistance of the joint of the new bridge and the old bridge can be greatly improved, and construction is convenient.
本申请提供一种桥梁加宽用新旧桥梁拼接构造及其施工方法，属于桥梁工程技术领域。本申请通过工字型截面梁连接新旧桥梁，所述工字型截面梁包括上翼板、腹板和下翼板，所述上翼板和所述下翼板间隔设置，所述腹板连接所述上翼板和所述下翼板，所述上翼板的两侧分别搭接在所述旧桥边梁翼板和所述新桥边梁翼板上方，所述下翼板的两侧分别抵接所述旧桥边梁翼板和所述新桥边梁翼板的下方，并通过所述所述梁托支撑在所述旧桥边梁腹板和新桥边梁腹板上，所述梁托与所述旧桥边梁腹板和新桥边梁腹板之间夹设有所述弹簧支座，所述腹板夹设于所述旧桥边梁翼板和所述新桥边梁翼板之间。本申请可以使新旧桥梁连接处抵抗变形能力得到大幅提升，且方便施工。
