Detectable, replaceable and adjustable arch bridge suspender system and method for constructing same

Abstract

The invention discloses a detectable, replaceable and adjustable arch bridge suspender system and a method for constructing the same. The arch bridge suspender system comprises a suspender, an upper anchor head steel structure and a rigid connecting screw. The suspender is provided with an upper anchor head, a middle suspender body and a lower anchor head, the upper anchor head steel structure is positioned on an arch rib of an arch bridge and is welded with the arch rib, the upper anchor head of the suspender extends outwards after penetrating through the arch rib and the upper anchor head steel structure, an extending end of the upper anchor head is anchored on the upper anchor head steel structure via an upper anchoring unit, the upper end of the rigid connecting screw is detachably and integrally connected with the lower anchor head of the suspender, and the lower end of the rigid connecting screw is anchored on the bottom surface of a crossbeam via a lower anchoring unit after penetrating through the crossbeam of the arch bridge. The arch bridge suspender system is convenient to check and replace, and force of the suspender can be adjusted conveniently. The invention also discloses the method for constructing the arch bridge suspender system. By the method for constructing the arch bridge suspender system, the detectability, the replaceability, the adjustability and excellent corrosion resistance of the arch bridge suspender system can be guaranteed.

Description

technical field [0001] The invention relates to an arch bridge suspender system and a construction method thereof, in particular to a checkable, replaceable and adjustable arch bridge suspender system and a construction method thereof. Background technique [0002] At present, the suspension rod system is commonly used in arch bridges. The common structure of the arch bridge suspender system in the prior art is as follows: figure 1 As shown, the arch rib 6 of the arch bridge is embedded with a vertical circular casing 101 from top to bottom, a horizontally arranged annular backing plate 102, a vertically arranged upper embedded pipe 15, and embedded in the beam 19 of the arch bridge. There are lower pre-embedded pipes 16 arranged vertically. These pre-embedded parts are used as the protective coat of the arch bridge suspender system, and are constructed before the suspender system is installed, and are pre-buried in the arch bridge. The arch bridge suspender system include...

AI Technical Summary

Problems solved by technology

[0010] The arch bridge replacement suspender system of the present invention adopts the steel structure of the upper anchor head to move the anchoring position of the upper anchor head of the suspender from the inside of the arch rib to the outside of the arch rib, which solves the problem of difficult inspection of the upper anchor head of the traditional arch bridge suspender system, making the bridge construction In-process tensioning, anchoring and boom force adjustments during operation are made easy and feasible
