Abstract
A prestressed concrete double-deck box girder bridge comprises an upper deck, a lower deck, a box girder bottom deck, lower deck plate stiffeners, top deck stiffeners, a box girder top deck and a pier, wherein the upper desk is arranged on the box girder top deck; the top deck stiffeners are uniformly distributed on the lower surface of the box girder top deck in a longitudinal direction of a bridge body; the lower deck is arranged between the box girder bottom deck and the box girder top deck; the lower deck plate stiffeners are uniformly distributed on the lower surface of the lower deck in a longitudinal direction of the bridge body; the lower deck plate stiffeners are arranged between the lower deck and the box girder bottom deck; and the pier is arranged on the lower surface of the box girder bottom deck. According to the prestressed concrete double-deck box girder bridge provided by the invention, the interior space of a prestressed concrete double-deck box girder is utilized for vehicles to run so that land resources are sufficiently utilized, lands for traffic construction are reduced and the manufacturing cost is low.
Description
Technical field
The present invention relates to a kind of box girder bridge, specially a kind of prestressed concrete double deck box girder bridge.
Background technology
The current dual deck bridge overwhelming majority is steel truss structure, and form is single and cost is of a relatively high.Prestressed concrete
Native Box Continuous are succinct due to version, and good looking appearance, torsional property is good, and the cross direction profiles under uneven loading action are than other shapes
The beam of formula is good, so be promoted quickly in recent years, but it mostly is individual layer and uses, bridge space is not utilized effectively.
The content of the invention
To solve above-mentioned technical problem, the present invention is achieved through the following technical solutions：
A kind of prestressed concrete double deck box girder bridge, including upper deck of bridge, lower floor's bridge floor, box beam base plate, lower floor's bridge
Panel ribbed stiffener, top board ribbed stiffener, box beam top board and bridge pier, the upper deck of bridge is arranged on box beam top board, the box beam top
Plate lower surface is longitudinally evenly distributed with top board ribbed stiffener along pontic, lower floor's bridge floor be arranged at box beam base plate and box beam top board it
Between, lower floor's bridge floor lower surface is longitudinally evenly distributed with lower floor's floorings ribbed stiffener along pontic, and lower floor's floorings are put more energy into
Rib is arranged between lower floor's bridge floor and box beam base plate, and the lower surface of the box beam base plate is equipped with bridge pier.
Further, also including web, the box beam base plate is closed form, and the top board floorings ribbed stiffener extends to abdomen
Plate is simultaneously combined with web.
Preferably, the box beam base plate is opening form.
Further, also including beam-ends deep floor and span centre deep floor, the beam-ends deep floor is arranged at box beam end
Face, the beam-ends deep floor is arranged at upper deck of bridge lower surface, and the span centre deep floor is arranged at upper deck of bridge and lower floor
Between bridge floor.
The invention has the advantages that：In the base of existing prestressed concrete continuous beam, continuous rigid frame, T structures etc.
It is that the use function of meeting double deck increases by one layer of driving road surface in case, in existing pre-stressed box girder construction on plinth
Construction, adapt to the driving road surface that double deck provides the enough use headroom of lower floor bridge floor and smooth-going；Mitigate bridge structure certainly
Weight, is changed to the form of thin plate plus cross rib, in order to mitigate deadweight, by common box beam bottom by carriageway plate in the top board and case of box beam
Plate is changed to opening form.Additionally, driven a vehicle using the intracavity space of inherent stress concrete box-beam, to make full use of land resource,
Reduce transport development to take up an area and cheap.

Specific embodiment
Below in conjunction with the accompanying drawings and embodiment further illustrates the present invention.
A kind of prestressed concrete double deck box girder bridge, including upper deck of bridge 1, lower floor's bridge floor 2, box beam base plate 3, lower floor
Floorings ribbed stiffener 7, top board ribbed stiffener 8, box beam top board 9 and bridge pier 11, the upper deck of bridge 1 is arranged on box beam top board 9, institute
State the lower surface of box beam top board 9 and be longitudinally evenly distributed with top board ribbed stiffener 8 along pontic, lower floor's bridge floor 2 is arranged at box beam base plate 3
Between box beam top board 9, the lower surface of lower floor's bridge floor 2 is longitudinally evenly distributed with lower floor floorings ribbed stiffener 7 along pontic, described
Lower floor floorings ribbed stiffener 7 is arranged between lower floor's bridge floor 2 and box beam base plate 3, and the lower surface of the box beam base plate 3 is equipped with bridge
Pier 11.Described prestressed concrete double deck box girder bridge also include web 10, the box beam base plate 3 be closed form, institute
State top board ribbed stiffener 8 to extend to web 10 and combined with web 10.The box beam base plate 3 is opening form.Described prestressing force
Concrete double bridge floor box girder bridge also includes beam-ends deep floor 4 and span centre deep floor 5, and the beam-ends deep floor 4 is arranged
In box beam end face, the beam-ends deep floor 4 is arranged at the lower surface of upper deck of bridge 1, and the span centre deep floor 5 is arranged at upper strata
Between bridge floor 1 and lower floor's bridge floor 2.
It is to meet making for double deck on the basis of existing prestressed concrete continuous beam, continuous rigid frame, T structures etc.
Two improvement have been done with function：
First, increase by one layer of driving road surface in case, for the construction in existing pre-stressed box girder construction, to adapt to double-decker bridge
Face just must provide for the driving road surface of the enough use headroom of lower floor's bridge floor and smooth-going；
2nd, mitigate bridge structure deadweight, carriageway plate in the top board and case of box beam is changed to into the form of thin plate plus cross rib, be
Mitigate deadweight, common box beam base plate can be changed to opening form.
Although being illustrated to invention intention with combined bridge, this is not the essence of this bridge structure invention, only
It is that the mode that used of patent of the present invention is different, that is to say, that be used for highway for railway, below above, or up and down
All it is used for highway, or is all possible for railway up and down.The invention is using the inner chamber of inherent stress concrete box-beam
Space is driven a vehicle, and to make full use of land resource, is reduced transport development and is taken up an area, and is had especially for densely populated area bigger
Realistic meaning.
