Not constituting conflict each other can just be mutually combined.
Rail track traffic two-wire track girder, including the left box beam 2 being erected on bridge pier 1 are embraced in a kind of reference picture 3, magnetic suspension
With right box beam 3, the left box beam 2 is identical with the structure of right box beam 3, and the left box beam 2 is arranged on by a left support abutment 4
On the bridge pier 1, the right box beam 3 is arranged on the bridge pier 1 by a right support abutment 5, the left support abutment 4 and right support abutment 5
Structure it is identical；
The horizontal gird 6 that passes on left of the right side of the left box beam 2 and the right box beam 3 is fixed together,
In addition, the horizontal gird 6 it is overall in rectangular shape and its be made up of armored concrete；
The horizontal gird 6 is arranged at the surface of the bridge pier 1, and there is spacing between the bridge pier 1.
The present invention is not simply to set crossbeam and is simply superimposed with reducing bearing, but is handed over according to magnetic-levitation
The characteristics of logical, selection pouring reinforcement concrete formation crossbeam at the position of bridge pier 1, it is ensured that profile it is attractive in appearance, in temperature change
In the case of influence to track form it is smaller.Left and right two box beams are obtained by the connection of horizontal gird 6, its integral rigidity
It is greatly improved, more than 3 times of rigidity during to be separately provided left and right two panels single-beam.The lifting of the rigidity of structure, subtracts significantly accordingly
Deformation during small structure stress, meets magnetic and floats strict demand of the engineering for structural deformation.
The present invention due in box beam position corresponding with bearing be provided with horizontal gird 6, the four of corresponding support box beam
Individual bearing can be reduced to two bearings, and the top cap lateral dimension of bridge pier 1 can reduce 35%, and the overall dimensions of bridge pier 1 are reduced to be saved simultaneously
Bottom pile foundation stake is about 25%.Therefore, by optimizing the bearing plan of establishment, the manufacturing cost of bearing can be made to reduce 50%,
The cost 35% of bridge pier 1 is reduced, bottom pile foundation cost 25% is reduced.
Further, the left box beam 2 and the right box beam 3 are hollow structure, and the dead load of box beam is greatly reduced, made
Box beam makes, sets up all more convenient, and box beam holistic cost is saved more.
Further, the horizontal gird 6, left box beam 2 are concordant with the bottom face of right box beam 3, and left box beam 2 and right box beam 3 are led to
Cross horizontal gird 6 to link together, integral rigidity improves more than 3 times.Crossbeam is concordant with left and right box beam bottom, and its plastic simplicity is beautiful
See, the manufacture difficulty of box girder formwork can be reduced, save cost of manufacture.Meanwhile, crossbeam is concordant with left and right box beam bottom, it is to avoid section
It is mutated the structural stress mutation brought, it is to avoid box beam larger concentrated stress occurs with crossbeam connecting portion, makes structure stress
Uniformly, stress performance is further enhanced.
Further, the height of the horizontal gird 6 is the 2/5~4/5 of the height of left box beam 2, the height of the bearing
It is the 1/10 of the height of horizontal gird 6, the spacing between the crossbeam and the bridge pier 1 is 0.3m~0.5m, the level
The weight ratio of reinforcing bar and concrete is 0.2 in crossbeam 6：1~0.5：1, the thickness of the horizontal gird 6 be its length 1/10~
1/5, its structural volume is more relative to left and right two panels box beam very little, and especially beam thickness is relatively thin, conducts oneself with dignity smaller, subtracts accordingly
Lacked the dead load that left and right box beam is born, at the same also reduce bottom bridge pier, the load that pile foundation is born.In addition slim and graceful outer of crossbeam
Shape, adds daylighting effect under the bridge between two panels box beam, also enhances landscape effect.
Further, the tensile strength of the horizontal gird 6 is more than 10Mpa, and the compression strength of the horizontal gird 6 is more than
15Mpa, to adapt to the intensity requirement of track traffic.
As it will be easily appreciated by one skilled in the art that the foregoing is only presently preferred embodiments of the present invention, it is not used to
The limitation present invention, any modification, equivalent and the improvement made within the spirit and principles of the invention etc., it all should include
Within protection scope of the present invention.
