Background technology
With starting, it is necessary to build more across existing highway, railway, mountain valley, river course for China's transport development climax
Long-span arch bridge, main Types have CFST Arch Bridge, steel case arch, steel truss arch, concrete arch-type bridge etc..Wherein, double cantilevers
Horizontal Swing Construction is that arch bridge often uses construction.
The double cantilever level rotation swivel construction methods of arch bridge are that arch ring or whole superstructure are divided into two and half across existing respectively
The two sides in river (paddy) utilize landform or simple beam prefabrication and assembly construction into semiarch.Then two semiarch are turned respectively using power set
Move on bridge axle line position and making to reach designed elevation and close up into arch ring.Construction by swing can reduce substantial amounts of work high above the ground,
Temporary project less investment, work progress are safer efficiently.
For arch bridge Horizontal Swing Construction, bridge structure swivel is in place to be closed up mouthful absolute altitude and locks, it is necessary to adjust temporarily, with
Just finally linear into bridge is determined.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of arch bridge Horizontal Swing Construction and closes up mouth with double cantilevers
Interim regulation locked configuration, easily to adjust arc rib alignment and close up a mouthful relative position, and monitors the internal force status for closing up mouth.
Technical scheme is as follows used by the utility model solves its technical problem：
Arch bridge Horizontal Swing Construction of the present utility model closes up mouth with double cantilevers and adjusts locked configuration temporarily, is arranged at left side
Closure segment between arch ring, right side arch ring, it is characterized in that：It includes fixed support, closes up securing rod and pressure sensor, fixed
Support is correspondingly arranged in left side arch ring, right side arch ring closes up end and connection fixed thereto, closes up corresponding to securing rod is arranged at
Between two fixed supports, pressure sensor, which is arranged at, to be closed up between securing rod both ends and fixed support.
The beneficial effects of the utility model are can easily to adjust arc rib alignment and close up a mouthful relative position, and can be monitored
Close up the internal force status of mouth, it is preferential to meet to close up mouthful elevation and temporary locking；It is reasonable in design, securely and reliably, simple operation.

Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Referring to figs. 1 to Fig. 4, arch bridge Horizontal Swing Construction of the present utility model closes up mouth with double cantilevers and adjusts locking structure temporarily
Make, the closure segment being arranged between left side arch ring 11, right side arch ring 12.It includes fixed support 20, closes up securing rod 30 and pressure
Force snesor 25, fixed support 20 is correspondingly arranged in left side arch ring 11, right side arch ring 12 closes up end and connection fixed thereto, closes
Hold together securing rod 30 be arranged at corresponding between two fixed supports 20, pressure sensor 25 be arranged at close up the both ends of securing rod 30 with
Between fixed support 20.Each control point absolute altitude of the preliminary rear repetition measurement arch rib in place of left side arch ring 11, the horizontal swing of right side arch ring 12, leads to
Cross rotor system dorsal funciculus to close up after the fine setting of securing rod 30 makes arch rib line style meet design requirement, lock interim connection.
Reference picture 4, the securing rod 30 that closes up is by nut 31 and the left side bolt 32 screwed in it, the structure of right side bolt 33
Into left side bolt 32, the hand of spiral of right side bolt 33 are opposite.Reference picture 4 and Fig. 5, the fixed support 20 is by vertical support
Steel plate 21, horizontal supporting steel plate 22, backing plate 23 and supporting steel 24 are formed, vertical support steel plate 21, the horizontal supporting to intersect
The inner and the end that closes up of left side arch ring 11 or right side arch ring 12 of steel plate 22 are welded to connect, and backing plate 23 is weldingly fixed on vertical support
The outer end of steel plate 21, horizontal supporting steel plate 22, supporting steel 24 are weldingly fixed on backing plate 23.Reference picture 4, it is described to close up locking
The end of bar 30 is supported by supporting steel 24, and in setting bayonet lock therebetween, limitation is relatively rotated, and pressure sensor 25 is set
In closing up between the end face of securing rod 30 and backing plate 23.
Double cantilevers close up mouth adjust temporarily locking process it is as follows：
1st, interim connection shaped steel 10 (shaped steel 10 illustrates middle finger and is shown with mistake, please change, and indicates channel-section steel, is not rod member) limit is taken
The position of arch rib top-bottom chord processed, it is ensured that each connecting rod relative position of arch rib is fixed, and closes up missing relatively for mouth to reduce
Difference；
2nd, each attaching plate elements of arch rib is avoided, sets arch ring to connect locking device temporarily, including is arranged at left side arch ring 11, the right side
Side arch ring 12 closes up the fixed support 20 of end and connection fixed thereto；
3) close up the total length of securing rod 30 according to closure segment measured distance, adjustment during practice of construction, put it into supporting
In groove, locking pin, rotation closes up securing rod 30 and applies top；
4) pressure sensor 25 is used to determining that arch rib to close up mouth closes up internal force.By arch rib dorsal funciculus and close up securing rod 30
The axle power for closing up mouth can accurately be adjusted.
5) after interim connection locking, lifting welding each steel plate of closure segment, and most this temporary connection is removed at last.
The utility model arch bridge Horizontal Swing Construction described above that simply explains through diagrams closes up mouth with double cantilevers and adjusted temporarily
Some principles of locked configuration are saved, are not intended to for the utility model to be confined to shown and described concrete structure and the scope of application
It is interior, therefore every corresponding modification for being possible to be utilized and equivalent, belong to the apllied the scope of the claims of the utility model.
