Fabricated reinforcing device and method for small-and-medium-span arch bridge
The invention discloses a fabricated reinforcing device and method for a medium-and-small-span arch bridge, and belongs to the technical field of reinforcing of medium-and-small-span arch bridges. The structure comprises prefabricated standard blocks, embedded steel bars, jacks and longitudinal steel bars, the multiple prefabricated standard blocks are arranged side by side along the arc-shaped bottom face of an original bridge arch ring and arranged in multiple rows, every two prefabricated standard blocks close to the center position are connected through the corresponding jack, every two adjacent prefabricated standard blocks in the front-back direction are connected in a clamped mode through tenons and tenon grooves, and the longitudinal steel bars are arranged on the embedded steel bars. The embedded steel bars are installed in the centers of the prefabricated standard blocks and fixedly connected with the original bridge arch ring, and the longitudinal steel bars penetrate through and are connected with the prefabricated standard blocks in each row. The problems of facilitating industrial standardized production, saving the engineering quantity of supports and cast-in-place formworks, guaranteeing the quality of components and improving the deformation coordination of the newly-added cover arch and the original arch ring are solved, the industrial standardized production is facilitated, the engineering quantity of the supports and the cast-in-place formworks is saved, the strength of the newly-added cover arch is guaranteed, and meanwhile the deformation coordination of the newly-added cover arch and the original arch ring is improved.
一种中小跨径拱桥的装配式加固装置及方法，属于中小跨径拱桥加固技术领域。其包括预制标准块、植筋、千斤顶和纵向钢筋，多个预制标准块沿原桥拱圈的弧形底面并排设置，且设置有多列，靠近中心位置的两个预制标准块通过千斤顶连接，每前后相邻两个预制标准块之间通过凸榫和凸榫凹槽建立卡装连接，预制标准块的中心处安装有植筋，植筋与原桥拱圈固定连接，纵向钢筋贯穿连接每排预制标准块。解决便于工业标准化生产，节省支架、现浇模板工程量，保证构件质量，提高新增套拱与原拱圈的变形协调性的问题，便于工业化、标准化生产，节省支架、现浇模板工程量，保证新增套拱强度的同时，提高新增套拱与原拱圈的变形协调性。
