Description

A kind of Concrete Filled Steel-tube Truss Arch Bridge suspender replacement special tool boom system

Technical field

The utility model relates to field of bridge construction, refers to a kind of Concrete Filled Steel-tube Truss Arch Bridge suspender replacement special tool boom system particularly.

Background technology

Along with the development of economic society, steel arch bridge, the construction comprising concrete-filled steel tubes arch bridge gets more and more, and suspension rod is the component of its most critical.At present, China has implemented the suspender replacement of many concrete-filled steel tubes arch bridge, define multiple suspender replacement implementation method, wherein the most commonly arch ring top is symmetrical in suspension rod and arranges leveling unit, leveling unit arranges semi girder, and under bridge deck crossbeam, be symmetrical in suspension rod pocket device for hoisting is set, by punching jack tension fining twisted steel or steel strand at the bottom of vault or crossbeam, suspension rod power is transformed on interim instrument derrick rig.This kind of instrument derrick rig can be replaced in the equivalence of realizable force preferably, but for the concrete-filled steel tubes arch bridge of Long span, arrange leveling unit at arch ring top generally need bar planting or be welded and fixed, arch ring can be damaged like this, affect bearing capacity, after removing, generally can cause larger impact to arch ring outward appearance simultaneously.

Summary of the invention

The purpose of this utility model is exactly the deficiency that will solve above-mentioned background technology, provides a kind of Concrete Filled Steel-tube Truss Arch Bridge suspender replacement special tool boom system.

The technical solution of the utility model is: a kind of Concrete Filled Steel-tube Truss Arch Bridge suspender replacement special tool boom system, is characterized in that: comprise batten plate, leveling unit, tensioning system, interim suspension rod and pocket device for hoisting; Described batten plate is fixed on the arch ring below steel pipe main arch; Described leveling unit is arranged on batten plate centre position, is arranged in the both sides of suspension rod to be replaced in mode symmetrical between two; Described interim suspension rod upper end is connected with tensioning system through the truss of main arch steel pipe composition, and lower end is connected with pocket device for hoisting through the bridge floor below suspension rod to be replaced; Described tensioning system is fixed on the level leveling face of leveling unit; Described pocket device for hoisting two ends are fixed on the floor beam lower end of suspension rod vertical lower to be replaced by interim suspension rod.

Further described leveling unit comprises levelling cushion block; Described levelling cushion block lower surface laminating batten plate, upper end is provided with the horizontal plane of fixing tensioning system.

Further described pocket device for hoisting comprises shoulder pole girder; Described shoulder pole girder two ends are connected with interim suspension rod, and upper surface contacts with the lower surface of the floor beam of suspension rod vertical lower to be replaced.

The utility model fixes tensioning system by levelling cushion block, avoid the globality destroying steel pipe arch ring, do not affect the intensity of steel pipe arch ring, levelling cushion block is fixed on batten plate can remove and reuses in addition, reduce the cost changing suspension rod, save the working time, installation and maintenance easy construction, there is larger promotional value.

Detailed description of the invention

A kind of Concrete Filled Steel-tube Truss Arch Bridge suspender replacement special tool boom system as shown in Figures 1 to 3, comprise the batten plate 9 be fixed on steel pipe main arch bottom arch ring 1, batten plate 9 on steel pipe arch ring 1 is general with the gradient, if being directly arranged on by tensioning system 2 on batten plate 9 to make the pulling force of below not maintain vertical direction, therefore need to increase leveling unit 3.Leveling unit 3 is fixedly mounted on the centre position of batten plate 9 on main arch bottom arch ring 1.

Leveling unit 3 is for having the levelling cushion block identical with batten plate 9 gradient, levelling cushion block can form as required in interim concrete or other materials cast, levelling cushion block upper end horizontal plane installs tensioning system 2, and tensioning system 2 can be made like this to transmit the power of vertical direction.

Tensioning system 2 is fixed on levelling, the lower end of tensioning system 2 connects interim suspension rod 5, interim suspension rod 5 is fixed on tensioning system 2 through batten plate 9 and levelling cushion block, the hole that batten plate 9 and levelling cushion block bore is the vertical holes of vertical level, the connection of interim suspension rod 5 so not only can be facilitated to pass through, the movement of interim suspension rod 5 transverse direction can also be limited.Interim suspension rod 5 is generally arranged symmetrically in two side positions of suspension rod 4 to be replaced along bridge floor trend, be to ensure uniform force in stretching process like this.

Interim suspension rod 5 lower end connection flat spreader beam, the two ends of shoulder pole girder, by the crossbeam 7 being fastened on below suspension rod 4 to be replaced of interim suspension rod 5, are transferred on interim suspension rod 5 by the weight of shoulder pole girder by suspension rod 4 bridge section to be replaced.

During use, levelling cushion block is arranged on the batten plate 9 above suspension rod 4 to be replaced, centered by suspension rod 4 to be replaced, symmetry arrangement between two, levelling cushion block upper end horizontal plane fixes tensioning system 2, tensioning system 2 is generally jack, and the lower end of tensioning system 2 is connected with shoulder pole girder by interim suspension rod 5, and shoulder pole girder contacts with crossbeam 7.Regulate tensioning system 2 to make interim suspension rod 5 receive vertical load, interim suspension rod 5 is stressed to be delivered on shoulder pole girder, and shoulder pole girder holds up the weight of suspension rod 4 bridge section to be replaced, changes suspension rod 4 to be replaced, installs new suspension rod.

After suspender replacement completes, put a tensioning system 2, first remove interim suspension rod 5, shoulder pole girder, then remove tensioning system 2, wherein levelling cushion block can be removed, and carries out protection work, so that reuse later.

The utility model fixes tensioning system by levelling cushion block, avoid the globality destroying steel pipe arch ring, do not affect the intensity of steel pipe arch ring, levelling cushion block is fixed on batten plate can remove and reuses in addition, reduce the cost changing suspension rod, save the working time, installation and maintenance easy construction, there is larger promotional value.
