In-service large-span continuous box girder spanning type widening connecting structure and construction method of in-service large-span continuous box girder spanning type widening connecting structure
The invention relates to an in-service large-span continuous box girder spanning type widening connecting structure and a construction method thereof. The structure comprises a connecting main piece which comprises a plurality of groove-shaped pieces, a top plate and a plurality of solid blocks; the connecting accessory comprises a plurality of wedge-shaped solid blocks and a box-shaped piece matched with the other ends of the wedge-shaped solid blocks; when the existing old bridge and the widening new bridge generate displacement or generate deflection difference, the connecting main piece vertically rotates along the central shaft of the spherical hinge, and the wedge-shaped solid block and the connecting main piece generate relative displacement, so that the connecting main piece and the connecting accessory generate limited displacement. The construction method comprises the following steps that a new bridge pavement and an old bridge pavement are installed; mounting the supporting piece; and the main connecting piece and the auxiliary connecting piece are assembled and installed on the widening new bridge and the existing old bridge correspondingly. Compared with the prior art, the problem of slab staggering possibly existing at the splicing seam position of a traditional expansion joint is solved, and the comfort of crossing driving of a vehicle is improved.
本发明涉及一种在役大跨径连续箱梁跨越式拼宽连接结构及其施工方法。该结构包括：连接主件，其包括若干槽型件、顶板、以及若干实心块；以及连接副件，其包括若干楔形实心块、以及与若干楔形实心块另一端匹配的箱型件；当既有旧桥与拼宽新桥发生位移或产生挠度差，所述连接主件沿球铰中心轴的发生垂直转动，楔形实心块与连接主件发生相对位移，使得连接主件与连接副件发生有限位移。该施工方法包括以下步骤：安装新桥铺装、旧桥铺装；安装支撑件；组装连接主件、连接副件并分别安装于拼宽新桥和既有旧桥。与现有技术相比，本发明消除了传统伸缩缝可能在拼接缝位置处存在的错台问题、提高了车辆跨越行驶的舒适性。
