The present invention relates to an arch bridge structure, in particular, a reinforcement device of a tied-arch bridge. The reinforcement device of the tied-arch bridge comprises hanger rods; the upper ends of the hanger rods are connected with an arch rib, and the lower ends of the hanger rods are connected with a tie beam; the hanger rods are uprightly connected between the arch rib and the tie beam; the reinforcement device of the tied-arch bridge further comprises lug plates; each lug plate includes a pouring portion and a connection portion, wherein the pouring portion is built in the tie beam, and the connection portion protrudes out from the upper part of the tie beam; the bottoms of the hanger rods are hinged and fixed to the connection portions; the tops of the hanger rods are provided with tensioning devices; the tensioning devices are fixed on the arch rib in a pressing manner; each hanger rod comprises a pull cable and an upper pre-buried tube which sleeves the upper end of the pull cable; a plurality of positioning holes are formed in each pouring portion; hollow positioning tubes pass through the positioning holes; and the positioning tubes are V-shaped. According to the reinforcement device of the tied-arch bridge of the present invention, the arch rib can be effectively supported, the pre-tightening of the hanger rods can be facilitated, and connection is firm, and the axes of the hanger rods can be finely adjusted according to needs.
Description
technical field [0001] The invention relates to an arch bridge structure, in particular to a reinforcing device for a tied arch bridge. Background technique [0002] In the existing concrete tied arch bridge, the upper end of the suspender is fixed on the arch rib, and the lower end is connected with a tensioning device for tensioning the suspender, and the tensioning device is poured inside the tie beam. When this type of suspender adjusts the tightness of the suspender, it is necessary to adjust the tensioning device at the bottom of the tie beam. The adjustment end is at the bottom of the tie beam, which is inconvenient for the staff to operate and apply force to the tensioning device. And the tensioning device is poured inside the tie beam, and when the suspension rod is connected with the tensioning device, the axial position of the suspension rod is fixed, which is not convenient for fine-tuning of the suspension rod position. [0003] As publication number is: a kind...
