Description
Technical field
The utility model is related to bridge structure technical field, in particular to a kind of short tower steel truss girder cable-stayed bridge of steel.
Background technology
Traditional concrete low-pylon cable-stayed bridge, due to the self-characteristic of concrete-bridge, concrete creep is larger after construction,
It is difficult to meet requirement of the high-speed railway to vertical displacement of being crept after work.And the superstructure of concrete-bridge is heavier, while beam
Portion's concrete shrinkage and creep shortens, and off normal is produced to bridge pier and basis, and larger stress is produced in beam body, bridge pier and pile foundation.
The content of the invention
The short tower of concrete that the purpose of this utility model seeks to solve in the prior art mentioned in above-mentioned background technology is oblique
Bridge is drawn to there is the shortcomings of creep after work that vertical displacement is big, produce off normal to act on bridge pier and basis, there is provided a kind of short tower steel truss of steel
Girder stayed-cable bridge.
The technical solution of the utility model is：A kind of short tower steel truss girder cable-stayed bridge of steel, including basis, pour on the basis of
Cushion cap and the bridge pier being supported on cushion cap, it is characterised in that：Also include as the steel truss girder of bridge beam body and for supporting steel
The bridge tower of trusses；Described steel truss girder is that, along the truss structure set up to direction along bridge, steel truss girder is fixed on bridge tower；Described
Bridge tower lower end is held on bridge pier upper end, bridge tower along bridge to both sides be provided with multiple skew cables；The upper end of described suspension cable is consolidated
It is scheduled on bridge tower, anchoring lower ends are on steel truss girder.
Further described bridge pier upper end is provided with pinner；Described pinner upper end is provided with bearing；Described bridge tower
Lower end is shelved on bearing.
Further described bridge tower includes two columns for being shelved on bearing upper end；Described two root posts are along direction across bridge
Direction arranged for interval, middle setting has crossbeam；The direction across bridge two ends of the crossbeam are separately fixed in two root posts and column-type
Into the tower column structure of H types.
Further described steel truss girder includes bridge deck；The both sides of described bridge deck are respectively arranged with along suitable bridge to cloth
The top boom and lower boom put, diagonal brace is provided between the upper and lower chord member；Between two top booms of bridge deck both sides
Horizontal-associate is provided with, horizontal-associate is located at bridge deck top.
Advantage of the present utility model has：1st, by using steel truss girder as bridge beam body, Bridge Beam can effectively be solved
Crept after body work the larger problem of vertical displacement, steel truss girder does not have shrinkage and creep, high-speed railway can be met to Xu after beam body work
Become the requirement of vertical displacement, while Construction of Steel Structure is convenient, the construction period can be saved；
2nd, by setting bearing between bridge pier and bridge tower, bridge tower, bridge pier are separated in the horizontal direction, is solved
The very big horizontal applied force produced when the bridge beam body temperature deformation of traditional Pylon pier consolidation structure and shrinkage and creep is to bridge pier
With the detrimental effect on basis, level will not be produced to pier footing when the isolating construction beam body temperature deformation of tower pier and shrinkage and creep
Power, improves bridge pier of knowing clearly, the stress on basis；
3rd, the mode for by using tower pier separate, can effectively reduce the scale on bridge pier, cushion cap and basis, reduce construction
Difficulty and cost, improve bridge economic performance.
The utility model simple structure, by using steel truss girder as bridge beam body, creeps after no work, can preferably fit
The requirement of high-speed railway travel safety and comfortableness is answered, while Construction of Steel Structure is convenient, the construction period can be saved；Tower pier point
Horizontal force will not be produced to pier footing, improve bridge pier of knowing clearly, the stress on basis when deforming from structural beams temperature.

Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Such as Fig. 1~3, a kind of short tower steel truss girder cable-stayed bridge of steel, including basis 1, basis 1 is anchored on ground, used as whole
The carrying basis of bridge, cushion cap 2 has been poured on basis 1, and bridge pier 3 has been poured on cushion cap 2,.The present embodiment is provided with multiple bridge piers
3, as shown in figure 1, multiple bridge pier 3 along along bridge to direction arranged for interval, for supporting bridge beam body.
As shown in Fig. 1~2, the upper end of bridge pier 3 is provided with pinner, and pinner upper end is provided with bearing 12, and bridge tower lower end is shelved on
On bearing 12.Bridge tower includes two columns 4 for being shelved on the upper end of bearing 12, two root posts 4 along direction across bridge direction arranged for interval, in
Between be provided with crossbeam 5, the direction across bridge two ends of crossbeam 5 are separately fixed in two root posts 4 tower column structure that H types are formed with column 4.
The bridge beam body of the present embodiment uses steel truss structure, steel construction for concrete structure, lighter in weight,
There is no shrinkage and creep after construction, be conducive to high-speed railway to drive a vehicle.As shown in figure 3, steel truss girder include bridge deck 7 (the present embodiment
The bridge deck structure such as including bridge floor and the high speed railway track being arranged on bridge floor), the both sides of bridge deck 7 are provided with two lower edges
Bar 9 and two top booms 8, upper and lower chord member be along along the steel construction being fixed on bridge tower from bridge to arrangement, two top booms 8 it
