Problems solved by technology

[0011] The object of the present invention is to provide a three-segment hinged arch bridge boom system with rigid tie rods combined with flexible stay cables. Inspection, replacement and adjustment of the boom force, and at the same time solve the problem of the horizontal stress on the steel tie rod caused by the centering error of the upper and lower pre-buried pipe holes caused by the deformation of the arch rib or the external force of the beam during the construction of a new bridge or in the operation process

Embodiment Construction

[0054] A three-section hinged arch bridge suspender system with rigid pull rods and flexible cables in the present invention is as follows: Figure 2 to Figure 13 As shown, it includes an upper steel tie rod 2, a suspender cable body 1, a lower steel tie rod 3 and a connecting member, wherein the upper steel tie rod 2 and the lower steel tie rod 3 are rigid tie rods, and the two upper steel tie rods 2 and the lower steel tie rods 3 Both ends have external threads, the suspender cable body 1 is a flexible cable, and the two rigid rods are located at the upper and lower ends. The upper steel rod 2 is fixedly connected with the upper anchor unit embedded in the arch rib 8 of the arch bridge, and the lower The steel tie rod 3 is fixedly connected with the lower anchor unit embedded in the beam 26 of the arch bridge. The upper end of the suspender cable body 1 is hinged with the upper steel tie rod 2 through the upper connecting member, and the lower end is connected with the lower ...

Abstract

The invention discloses a three-section hinging type arch bridge suspender system with rigid rods combined with a flexible cable. The three-section hinging type arch bridge suspender system comprises a suspender cable body, an upper steel rod, a lower steel rod and connecting components, wherein the upper steel rod and the lower steel rod are the rigid rods; the suspender cable body is the flexible cable; the two sections of rigid rods are located on the upper end and the lower end; the upper steel rod is fixedly connected with an upper anchor unit embedded in an arch rib of an arch bridge; the lower steel rod is fixedly connected with a lower anchor unit embedded in a cross beam of the arch bridge; the upper end of the suspender cable body is hinged with the upper steel rod through the upper connecting component; the lower end of the suspender cable body is hinged with the lower steel rod through the lower connecting component; therefore, a three-section hinging type structure with the rigid rods on two ends and the flexible cable in the middle is formed. The suspender system is adjustable, detectable and replaceable, is convenient for replacing and adjusting the suspender force, and solves the problem that horizontal stress is generated on the steel rods since centralizing error of upper and lower embedded pipe holes is caused by the deformation of the arch rib or exogenic action stressed by the cross beam during the new bridge construction or operation process.

Description

technical field [0001] The invention relates to an arch bridge suspender system, in particular to an arch bridge suspender system in the form of a three-segment hinge of a rigid tie rod combined with a flexible cable. Background technique [0002] At present, the common structures of the arch bridge suspender system in the prior art are as follows: figure 1 As shown, an upper anchoring unit is pre-embedded in the arch rib 8 of the arch bridge, and the upper anchoring unit includes an upper spherical nut 5 arranged from top to bottom and an upper anchor head 16 of the ring cable body, an upper spherical bearing 6 and an upper anchor pad The plate 7 and the upper spherical nut 5 are threadedly connected with the upper anchor head 16 of the cable body with external threads, so that the force of the boom cable body 1 is transmitted to the arch rib 8, and the upper anchor unit is poured with concrete after the construction is completed, and it is connected with the arch rib 8 It...
