Anchored type arch bridge suspender system combining flexible inhaul cable with rigid pull rod

Abstract

The invention discloses an anchored arch bridge suspender system with a flexible cable combined with a rigid tie rod. The suspender system includes a suspender cable body, an upper anchor head, an upper anchor member, a steel tie rod, a lower anchor head and a lower anchor member. The boom cable body is a flexible cable, the upper anchoring member is located in the anchor hole of the arch rib of the arch bridge, and the arch rib pre-embedded pipe is embedded in the arch rib, the upper end of the boom cable body is the upper anchor head, and the upper anchor After passing through the pre-buried pipe of the arch rib, the head is connected with the upper anchoring member. The steel tie rod is a rigid tie rod. The lower end of the suspender cable body is connected with the upper end of the steel tie rod through the cable rod connecting member. The lower anchoring member is located on the crossbeam of the arch bridge. In the anchor hole of the crossbeam, the crossbeam pre-embedded pipe is pre-buried in the crossbeam, and the lower end of the steel tie rod is the lower anchor head, which is connected to the lower anchor member after passing through the crossbeam pre-embedded pipe. The boom system uses a combination of flexible cables and rigid rods, which are adjustable, inspectable and replaceable.

Description

technical field [0001] The invention relates to an arch bridge component, in particular to an anchored arch bridge suspender system in which flexible cables are combined with rigid pull rods. Background technique [0002] At present, the common structure of the arch bridge suspender system in the prior art is as follows: figure 1 As shown, an upper anchoring unit is pre-embedded in the arch rib 10 of the arch bridge, and the upper anchoring unit includes an upper spherical nut 24, an upper spherical bearing 25 and an upper anchor pad 26 arranged from top to bottom and surrounding the upper anchor head 8, The spherical nut 24 is connected with the upper anchor head 8 of the suspender with external threads, so as to transmit the force of the suspender cable body 1 to the arch rib 10, and the upper anchor unit is poured with concrete after the construction is completed to form an integral body with the arch rib 10; 10 has an upper pre-embedded pipe 11 arranged vertically. The ...

Problems solved by technology

[0011] The object of the present invention is to provide an anchored arch bridge suspender system with a flexible cable combined with a rigid tie rod. The adjustment of the boom force also solves the problem of the horizontal stress on the new boom 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 the new bridge or during the operation process

[0013] The boom system of the present invention is a composite boom combined with rigid pull rods and
