Hollow slab beam hinge joint rapid maintaining and reinforcing structure and reinforcing method thereof
The invention relates to a hollow slab beam hinge joint rapid maintaining and reinforcing structure and a reinforcing method thereof. The hollow slab beam hinge joint rapid maintaining and reinforcing structure comprises prefabricated maintaining pieces for hinge joint maintaining, slab beam embedded steel bars, a UHPC concrete layer and an asphalt layer. The UHPC concrete layer and the asphalt layer are laid at the position of the pouring belt from bottom to top; the prefabricated parts are laid in the UHPC concrete layer, the upper ends of the plate-girder embedded steel bars make contact with the extending structures of the longitudinal steel bars, and the lower ends of the plate-girder embedded steel bars are suitable for extending into a pouring belt; the multiple prefabricated parts are arranged in the bridge deck direction according to a second preset interval, and the UHPC concrete filling layer is at least filled to be flush with the upper surfaces of the prefabricated parts. The transverse steel bars are longitudinally arranged on the channel steel at intervals, the longitudinal steel bars are arranged at the two longitudinal ends of the channel steel, and the prefabricated parts are manufactured in advance, so that the prefabricated parts have the advantages of being low in cost, easy to manufacture by implementation personnel in the field and low in cost while ensuring that the prefabricated parts have enough structural strength and reliable hinge joint repairing quality. And the problem of long operation time of a conventional maintenance process can be effectively solved.
本申请涉及空心板梁铰缝快速维修加固结构及其加固方法，包括铰缝维修用预制维修件、板梁植筋、UHPC混凝土层及沥青层；在灌注带位置自下至上铺设的UHPC混凝土层以及沥青层；预制构件铺设在UHPC混凝土层内，板梁植筋的上端与纵向钢筋的延伸结构相接触，板梁植筋的下端适用于延伸至灌注带内；预制构件的数量为多个，在顺桥面方向按第二预设间隔设置，UHPC混凝土填充层至少填充至与预制构件的上表面相齐平。通过在槽钢沿纵向间隔设置有多根横向钢筋，并且在槽钢的纵向两端设置有纵向钢筋，并预先制成预制构件，预制构件在确保具有足够结构强度，铰缝修复质量可靠的同时，具有成本低廉、易于本领域实施人员制备，能够有效解决常规维修工艺作业时间长的问题。
