New and old bridge cast-in-place continuous box girder splicing belt structure and splicing construction method
The invention discloses a new and old bridge cast-in-place continuous box girder splicing belt structure which comprises a hanging bracket and a bottom die, one end of the hanging bracket is connected to a flange plate of an old bridge continuous box girder in a hanging mode, one end of the hanging bracket is connected to a flange plate of a new bridge continuous box girder in a hanging mode, the bottom die is laid on the hanging bracket, and steel bars are planted at the flange position of the old bridge continuous box girder. And steel bars are reserved at the flanges of the new bridge continuous box girders and are connected with embedded steel bars at the flanges of the old bridge continuous box girders. The new and old bridge cast-in-place continuous box girder splicing belt structure has the advantages that the principle is simple, operation is convenient, the construction efficiency is high, the safety risk of high-altitude edge operation is reduced, the splicing belt construction quality is improved and the like, and a series of problems of new and old bridge cast-in-place continuous box girder splicing construction are solved. The invention further provides a new and old bridge cast-in-place continuous box girder splicing construction method.
本发明公开了一种新老桥梁现浇连续箱梁拼接带结构，包括吊架和底模，所述吊架的一端吊装连接在老桥连续箱梁的翼缘板上，吊架的一端吊装连接在新桥连续箱梁的翼缘板上，底模铺设在吊架上，在老桥连续箱梁翼缘处植筋，新桥连续箱梁翼缘处预留钢筋并与老桥连续箱梁翼缘处的植筋连接。本发明的新老桥梁现浇连续箱梁拼接带结构具有原理简单、操作方便、施工效率高、减小高空临边作业安全风险、提高拼接带施工质量等优点，解决了新老桥梁现浇连续箱梁新老现浇连续箱梁拼接施工系列难题。本发明还提供了一种新老桥梁现浇连续箱梁拼接施工方法。
