Description
Technical field
The utility model belongs to field of bridge construction, is applicable in the constructions such as arch bridge dismounting.
Background technique
20th century of China build bridge because operation the age it is longer, occur old unsafe bridge in various degree, some because traffic be saturated,
Navigation capacity is promoted, and bridge is unsatisfactory for requirement, and more and more bridges need to be removed in situ carries out reorganization and expansion construction.Bowstring arch bridge
Because combining arch bridge and beam bridge a little, it is widely used by last century.Because bowstring arch bridge is statically indeterminate system, Normal practice, tied arch
Bridge first sets up bracket, support tie bar and arch rib when removing in river, and then segmentation carries out arch rib dismounting.
It being continued to develop and is promoted by Navigation in Navigable, most of navigable river, which does not allow to carry out iceound or navigation hole width, to be reduced,
Cause part bowstring arch bridge that can not carry out bracket support when removing.
Utility model content
The purpose of this utility model is that: it proposes a kind of interim tie-rod device for the locking of bowstring arch bridge arch rib, is used for
Under the conditions of bowstring arch bridge is without bracket, the non-opposite sequence construction that binder removes arch rib again is first removed.
The utility model aim is realized by following technical proposals:
A kind of interim tie-rod device for the locking of bowstring arch bridge arch rib, interim tie-rod device are connected to the two of bowstring arch bridge
Between end arch foot side, interim tie-rod device includes finish rolling threaded tie-rods, nut and attachment base, and attachment base is fixed on bowstring arch bridge
Arch springing side, finish rolling threaded tie-rods are connected between the attachment base of both ends arch springing of bowstring arch bridge by nut.
Alternatively, attachment base includes wing plate and web, and wing plate is weldingly fixed on the arch springing side of bowstring arch bridge, and web connects
Fixed wing plate and arch springing are connect, finish rolling threaded tie-rods are connected on wing plate by nut.
The aforementioned main scheme of the utility model and its each further selection scheme can be freely combined to form multiple schemes,
It can be used for the utility model and claimed scheme；And the utility model, (each non conflicting selection) selection between and and
It can also be freely combined between other selections.Those skilled in the art after understanding the utility model according to the prior art and
Common knowledge can be illustrated there are many combination, be the claimed technical solution of the utility model, do not do exhaustion herein.
The course of work are as follows: utility model device is installed at tie-rod arch bridge abutment, and applies certain pretightning force, instead of
Arch bridge binder overcomes arch rib horizontal thrust.Tied arch can first remove binder, and arch rib is locked by the device, keep stable body
System realizes arch bridge opposite sequence without support removing.
The utility model has the beneficial effects that the Support Method dismounting technique that the device is more traditional, the device can be used for arch rib lock
Fixed, when arch bridge binder is first removed, arch rib will not occur that horizontal thrust is excessive structure destruction occurs, first remove binder again for arch bridge
The non-opposite sequence construction for removing arch rib, effectively prevents setting up bracket within the scope of navigable, and avoiding, which influences navigation channel, normally opens the navigation or air flight,
Save the cost improves construction efficiency, constructing operation conveniently.

Specific embodiment
Following non-limiting examples are for illustrating the utility model.
With reference to shown in Fig. 1-3, filled out for the device of bowstring arch bridge arch rib locking, including interim tie-rod device, expansion joint plug
Device and arch springing backpressure device.Interim tie-rod device is connected between 4 side of both ends arch springing of bowstring arch bridge, interim tie-rod device
Including finish rolling threaded tie-rods 5, nut 6 and attachment base, attachment base is fixed on 4 side of arch springing of bowstring arch bridge, finish rolling threaded tie-rods 5
It is connected to by nut 6 between the attachment base 16 of the both ends arch springing 4 of bowstring arch bridge；Attachment base 16 includes wing plate 7 and web 8, the wing
Plate 7 is weldingly fixed on 4 side of arch springing of bowstring arch bridge, and web 8 is connected and fixed wing plate 7 and arch springing 4, and finish rolling threaded tie-rods 5 pass through
Nut 6 is connected on wing plate 7.
Refering to what is shown in Fig. 4, expansion joint plug action includes rigid filler mechanism, rigid filler mechanism is respectively arranged on arch springing 4
Between end bay beam bridge 9, between each adjacent edge bridge bridge 9 between arch springing 4 and abutment 10 and end bay beam bridge 9 and abutment 10
Between single span freely-supported expansion joint 11 in, rigid filler mechanism rigid connection 11 both ends bridge mechanism of single span freely-supported expansion joint simultaneously pass
Pass 2 horizontal force of arch rib；Preferably, as shown in this embodiment, rigid filler mechanism is dense packing effect at single span freely-supported expansion joint
Filling steel plate 12 in 11.
With reference to shown in Fig. 5-6, arch springing backpressure device includes finish rolling screw thread 13, back-pressure beam 14 and nut 6, below arch springing 4
