New and old bridge buffering and limiting connection method and connection structure
The invention relates to a new and old bridge buffering and limiting connection method and structure. The new bridge and the old bridge are connected through a buffering and limiting connecting piece, the buffering and limiting connecting piece is composed of a new bridge connecting rigid connecting piece, an old bridge connecting rigid connecting piece and an elastic body, the new bridge connecting rigid connecting piece is connected with the new bridge, and the old bridge connecting rigid connecting piece is connected with the old bridge. A rigid connecting piece reserved upper gap and a rigid connecting piece reserved lower gap exist between the new bridge connecting rigid connecting piece and the old bridge connecting rigid connecting piece, and the elastic body is connected between the new bridge connecting rigid connecting piece and the old bridge connecting rigid connecting piece. Compared with the prior art, the new and old bridge buffering and limiting connecting method has the advantages that the reserved gap is formed in the buffering and limiting connecting piece, a part of deformation difference can be absorbed, and the shearing effect borne by the old bridge is reduced. Meanwhile, the reserved gap can be customized according to the requirements of the old bridge, and the splicing requirements of new and old bridges with different spans are met.
本发明涉及一种新旧桥缓冲限位连接方法与连接结构。在新桥、旧桥之间通过缓冲限位连接件连接，所述缓冲限位连接件由连接新桥刚性连接件、连接旧桥刚性连接件以及弹性体组成，所述连接新桥刚性连接件与新桥连接，所述连接旧桥刚性连接件与旧桥连接，所述连接新桥刚性连接件与连接旧桥刚性连接件之间存在刚性连接件预留上空隙以及刚性连接件预留下空隙，所述弹性体连接在所述连接新桥刚性连接件与连接旧桥刚性连接件之间。与现有技术相比，本发明提出了一种新旧桥缓冲限位连接方法，在缓冲限位连接件中设预留空隙，可以吸收一部分变形差，减少旧桥承受的剪切作用。同时预留空隙可根据旧桥需求进行定制，满足不同跨径新旧桥的拼接需求。
