Field be welded to connect work progress influence, under dead load, unit control Section Forces with once fall to put up bridge compare it is unreasonable,
Tension is bigger than normal, under bridge cyclic load, structural fatigue easily occurs, structural bearing capacity and durability is produced very big
Influence.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of steel box girder bridge Program for structural Transformation system, it is applicable
The structure safety stock during steel box girder bridge operation is improved.
A kind of steel box girder bridge Program for structural Transformation system, including：Steel box-girder (1), end bay bridge pier (2), permanent bearing (3),
Auxiliary pier (4), Temporary Piers (5), jack (6), temporary support (8)；Wherein：
Permanent bearing (3) is fixedly installed on end bay bridge pier (2)；Auxiliary pier (4) is located at mid-span span centre position, and described
Temporary support (8) is installed, for aiding in the installation of steel box-girder (1) in place on auxiliary pier (4)；Temporary Piers (5) are located at the side
On bridge pier (2), and jack (6) is installed on the Temporary Piers (5), the jack (6), which is used to uniformly apply, to be jacked
Power lifting steel box-girder (1) and the position recovery for being used for steel box-girder (1) after load removal.
Preferably, the steel box girder bridge Program for structural Transformation system also includes leveling steel plate (7), jack (6) upper and
It is close to by leveling steel plate (7) levelling, up-regulation plain plate with the bottom surface of steel box-girder (1) down.
Compared with prior art, the final internal force status of Program for structural Transformation system described in the utility model reaches once to fall
Rack-like state, and whole process is simple to operate, construction is quick, and system stress is clear and definite, structure is safe and reliable.

Embodiment
To make those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with the accompanying drawings to this reality
It is described in detail with the steel box girder bridge Program for structural Transformation system of new offer.
A kind of steel box girder bridge Program for structural Transformation system, including：Steel box-girder 1, bridge pier 2, permanent bearing 3, auxiliary pier 4, face
When pier 5, jack 6, leveling steel plate 7, temporary support 8.
End bay bridge pier 2 construct after the completion of, permanent bearing 3 is installed on bridge pier 2, after the permanent installation of bearing 3, mid-span across
It is middle to set up auxiliary pier 4, temporary support 8 is installed on auxiliary pier 4.
After the completion of the splicing of the scene of steel box-girder 1, welding, after correct lifting is attached to bridge location, temporary support 8 is removed.End bay bridge
Dun2Chu sets Temporary Piers 5, installs jack 6 on Temporary Piers 5, jack 6 it is upper and lower with the levelling of leveling steel plate 7, upper steel plate with
It is close at the bottom of steel box-girder 1.After jack 6 is installed in place, auxiliary pier 4 can be removed；Each jack 6 uniformly exerts a force, and jacks steel box-girder 1
To computed altitude, the welding of the mid-span of steel box-girder 1 is closed up.Respectively across jack 6, removal load, steel box-girder 1 force falling to jack-up simultaneously
Front position.After steel box-girder 1 sets back, jack 6 and Temporary Piers 5 are removed.
When in use, can carry out in accordance with the following steps：
(1) permanent bearing is installed after the completion of Bridge Pier Construction, on bridge pier；
(2) mid-span span centre sets up auxiliary pier, and temporary support is installed on auxiliary pier；
(3) after the completion of the splicing of steel box-girder scene, welding, correct lifting is attached to bridge location, sees Fig. 1；
(4) temporary support is removed, sees Fig. 2；
(5) Temporary Piers are set at end bay bridge pier, jack is installed on Temporary Piers, jack is upper and lower to use leveling steel plate levelling,
Upper steel plate is close to steel box-girder bottom；
(6) auxiliary pier is removed；
(7) each jack uniformly exerts a force, and steel box-girder is jacked to computed altitude；
(8) steel box-girder mid-span welding is closed up；
(9) while removal is respectively across jack load, and steel box-girder forces falling to jack-up front position；
(10) jack and Temporary Piers are removed.
Compared with prior art, the final internal force status of Program for structural Transformation system described in the utility model reaches once to fall
Rack-like state, and whole process is simple to operate, construction is quick, and system stress is clear and definite, structure is safe and reliable.
It is understood that embodiment of above is merely to illustrate that principle of the present utility model and used exemplary
Embodiment, but the utility model is not limited thereto.For those skilled in the art, this is not being departed from
In the case of the spirit and essence of utility model, various changes and modifications can be made therein, and these variations and modifications are also considered as this reality
With new protection domain.
