Abstract
The present invention is specially a kind of section combining structure of Wavelike steel webplate low-pylon cable-stayed bridge, solves the problems, such as that existing Wavelike steel webplate low-pylon cable-stayed bridge exists and is also easy to produce warping stress and section discontinuity.The section combining structure of Wavelike steel webplate low-pylon cable-stayed bridge, including box beam top plate and box beam bottom plate, two block concrete webs of left and right distribution are provided between in the middle part of box beam top plate and box beam bottom plate, and it is both provided with Wavelike steel webplate between the box beam top plate and box beam bottom plate at left and right sides of concrete web, concrete beam is both provided between the front and back end of two block concrete webs, the suspension cable for being pierced by box beam top plate is provided with the fillet surface of concrete beam, the bottom of suspension cable is provided with the anchorage fixed with concrete beam.The present invention has efficiently controlled the distortion deformation in section, ensure that the safety of structure, and ensure that the uniform stressed of box beam, while without separately setting tooth plate, has the advantages that simple in structure and easy for construction.
Description
Technical field
The present invention relates to the section structure of bridge, the section for being specially a kind of Wavelike steel webplate low-pylon cable-stayed bridge combines knot
Structure.
Background technology
Wavelike steel webplate prestressed concrete beam bridge thoroughly solves the stupid of conventional prestressed concrete beam bridge cracking in webs
Disease, and have the advantages that girder lightness, material use are efficient, anti-seismic performance is good, convenient construction, therefore, Wavelike steel webplate
Prestress box beam is promoted and applied soon after occurring.Wavelike steel webplate is used in the girder of low-pylon cable-stayed bridge（We
Referred to as Wavelike steel webplate low-pylon cable-stayed bridge）, the dead weight of girder is advantageously reduced, increases across footpath, reduce earthquake response, also favorably
In the rationalization of construction and the shortening of duration, construction cost is reduced.
Existing Wavelike steel webplate low-pylon cable-stayed bridge uses the section structure of prestressed concrete roof and floor+Wavelike steel webplate
Form, this section structure significantly reduce the dead weight of girder, increase the across footpath of bridge.But due to concrete top bottom
The stiffness difference of plate and Wavelike steel webplate is larger, and under uneven loading action, concrete roof and floor can produce larger warping stress, right
Structure is unfavorable safely.In addition, suspension cable is anchored in steel anchor box by the prior art, it is impossible to effectively transmits horizontal pull
Into concrete roof, section discontinuity is caused.
The content of the invention
The present invention in order to solve existing Wavelike steel webplate low-pylon cable-stayed bridge exist be also easy to produce warping stress and section stress not
A kind of the problem of uniform, there is provided section combining structure of Wavelike steel webplate low-pylon cable-stayed bridge.
The present invention adopts the following technical scheme that realization：The section combining structure of Wavelike steel webplate low-pylon cable-stayed bridge, bag
Box beam top plate and box beam bottom plate are included, two block concrete abdomens of left and right distribution are provided between box beam top plate and box beam bottom plate middle part
Plate, and it is both provided with Wavelike steel webplate, two block concretes between the box beam top plate and box beam bottom plate at left and right sides of concrete web
Concrete beam is both provided between the front and back end of web, is provided with the fillet surface of concrete beam and is pierced by the oblique of box beam top plate
Drag-line, the bottom of suspension cable are provided with the anchorage fixed with concrete beam.
The section combining structure by the way of corrugated steel web and concrete web coordinate in the middle part of box beam roof and floor it
Between form the concrete chamber of closure, enhance the space overall stiffness in section, reduce the distortion deformation in section, and then reduce
The warping stress of section concrete slab；Secondly, suspension cable is directly anchored on box beam top plate, and suspension cable is in the horizontal direction
Component is effectively transferred to box beam top plate, reduces loss of prestress, overcomes existing Wavelike steel webplate low-pylon cable-stayed bridge and exists
The problem of being also easy to produce warping stress and section discontinuity.
The present invention is reasonable in design reliable, and section rigidity is taken into account while mitigating beam body dead weight, has efficiently controlled section
The distortion deformation in face, ensure that the safety of structure, and horizontal force is effectively reached the top plate of box beam by the design of suspension cable, is protected
The uniform stressed of box beam has been demonstrate,proved, while by the use of the chamfered area of concrete beam as tooth plate, without separately setting tooth plate, there is structure
The advantages of simple and easy for construction.
