Description
Technical field
The utility model is related to anchor, specifically a kind of fixing cable anchoring dress for tubular arch Construction of Swivel of Arch Bridge
Put.
Background technology
With China railways, expressway construction project it is increasing, in face of orographic condition complicated and changeable, at some
The extremely complicated area swivel arch bridge of landform has obtained increasingly being widely applied.
When being constructed using erection by swing, main arch need to be coupled with border pier using button anchor cable system, it is common at present
Knotted rope has two kinds with the connecting method of tubular arch, and one kind is by welded connection hinge on tubular arch, particular by big steel pin
It is coupled with knotted rope；Another kind is the direct perforate on tubular arch, and knotted rope is anchored under tubular arch again directly through tubular arch perforate
Side.
No matter using hinge, or the perforate on tubular arch is welded on tubular arch, mother metal can be damaged, directly result in steel
The decline of pipeline overhead lifting tensile strength, can even influence the structural stability of whole steel pipe arch bridge when serious.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of fixing cable anchoring for tubular arch Construction of Swivel of Arch Bridge
Device, the device can overcome on tubular arch weld hinge or on tubular arch perforate can damage mother metal, cause tubular arch to draw
The decline of intensity is stretched, the problem of the structural stability of whole steel pipe arch bridge is influenceed.
In order to solve the above technical problems, the utility model is adopted the following technical scheme that：
A kind of fixing cable anchoring device for tubular arch Construction of Swivel of Arch Bridge, including knotted rope, tubular arch, anchorage, tubular arch
Arch rib top boom be connected saddle support beam, saddle support beam fixed saddle by upper stiffener；Under the arch rib of tubular arch
Chord member is connected lower anchor beam by lower stiffener, and lower anchor beam is provided with anchor hole, and anchor hole fixes knotted rope.
Using the utility model of above-mentioned technical proposal, it is compared with prior art, the characteristics of its protrusion：
By being respectively provided with upper stiffener, lower stiffener on arch rib top boom, arch rib lower boom, using being connected thereto fixation
Saddle, lower anchor beam be connected knotted rope, reduce on the premise of knotted rope damages to tubular arch mother metal, knotted rope and tubular arch can be made
Safe and reliable connection, simple structure, easy for installation, reliability are high.
Further optimal technical scheme is as follows：
Described saddle is fixed with saddle support beam by bolt hole, bolt connection.
Described saddle upper surface is provided with tetrafluoro plate bed course.Tetrafluoro plate bed course is 10mm thick, thick in saddle surface paving 10mm
Tetrafluoro plate bed course, can effectively reduce the frictional force between zip and saddle.
Described tubular arch is provided with stiffening ring, and stiffening ring is arranged on the connection of the upper stiffener of tubular arch connection or lower stiffener
Position.
12 circular holes of diameter 30mm are provided with described stiffening ring.
