Description
Technical field
This utility model is related to bridge structure technical field of buildings and in particular to a kind of high-speed railway steel reinforced concrete combines only tower portion
Divide cable-stayed bridge.
Background technology
For rail segment cable-stayed bridge, two kinds of most commonly seen versions are concrete and steel structural form.Concrete
Partial cable-stayed bridge, good rigidity, low cost, late maintaining workload are little, but because dead load is greatly so that span ability has
Limit, and the high area of inapplicable earthquake intensity；Steel construction partial cable-stayed bridge, dead load is little, span ability is strong, anti-seismic performance
Excellent, construction is ripe, but cost is high, late maintaining workload is big.
Content of the invention
The purpose of this utility model is to provide a kind of high-speed railway steel reinforced concrete to combine only tower section cable-stayed bridge so as to have coagulation concurrently
Native partial cable-stayed bridge and the advantage of both steel construction partial cable-stayed bridges.
The technical scheme that this utility model is adopted is：
A kind of high-speed railway steel reinforced concrete combine only tower section cable-stayed bridge it is characterised in that：
Including bridge pier, bridge pier pier top is provided with concrete box girder at bridge tower and middle pier；Bridge tower is H type, is arranged at middle Dun Chu
Concrete box girder both lateral sides；
At middle pier, concrete box girder both sides are provided with the vertically parallel steel truss of two panels, set respectively up and down between two panels steel truss
It is equipped with concrete roof and concrete floor, two panels steel truss outboard end is provided with concrete box girder at abutment pier, coagulation at abutment pier
Native box beam bottom is supported by abutment pier；
It is provided with suspension cable between bridge tower and steel truss.
Steel truss includes winding up and lower edge, winds up and is provided with the steel case web member being triangularly arranged, suspension cable and lower edge between
Bottom is fixed on and is winded up.
At middle pier, concrete box depth of beam is equal to concrete box girder at abutment pier, the high transition such as steel truss therebetween.
At middle pier, concrete box depth of beam is more than concrete box girder at abutment pier, and the two top surface is contour, steel therebetween
Purlin uprises transition in the sections of concrete box girder at middle pier.
It is provided with bearing between concrete box girder and bridge pier and at abutment pier between concrete box girder and abutment pier at middle pier.
The top board of concrete box girder arranges prestressed strand with concrete bottom intralaminar part.
This utility model has advantages below：
1）Rigidity is big, and driving power performance is good:
Compared with steel construction cable-stayed bridge, because beam portion top bottom surface adopts concrete slab, the integral rigidity of structure is remarkably reinforced.
2）Non-fragment orbit requirement can be better conformed to:
This structure is concrete roof and floor in that context it may be convenient to adapt to ballastless track structure, it is to avoid steel bridge laying no tiny fragments of stone, coal, etc. rail
A variety of technical barriers in road.
3）Low engineering cost maintenance quantities is little:
Because structure only chord member and web member adopt steel beam column, steel using amount and maintenance workload to be greatly decreased, engineering is made
Valency substantially reduces.
4）Beautiful design landscape effect is good:
Because this bridge adopts steel web member to substitute concrete web, structure permeability is good, merrily and lightheartedly attractive in appearance, and bridge site can be substantially improved
The landscape effect in area.

Specific embodiment
With reference to specific embodiment, this utility model is described in detail.
A kind of high-speed railway steel reinforced concrete that this utility model is related to combines only tower section cable-stayed bridge, including bridge pier 8, bridge pier 8 pier
Top is provided with concrete box girder 4 at bridge tower 7 and middle pier；Bridge tower 7 is H type, is arranged at concrete box girder 4 both lateral sides at middle pier.
At middle pier, concrete box girder 4 both sides are provided with the vertically parallel steel truss of two panels, are respectively arranged with mixed between two panels steel truss up and down
Solidifying soil top board 1 and concrete floor 3.Steel truss includes wind up 10 and lower edge 9, and winding up, it is triangular in shape to be provided between 10 and lower edge 9
The steel case web member 2 of arrangement.It is provided with suspension cable 6, suspension cable 6 bottom is fixed on and is winded up 10 between bridge tower 7 and steel truss.Two panels steel truss
Outboard end is provided with concrete box girder 5 at abutment pier, and at abutment pier, concrete box girder 5 bottom is supported by abutment pier.Concrete at middle pier
