Description
Technical field
The utility model is related to stayed-cable bridge bridge structure technical field, in particular to a kind of only post wide cut rachis face half
Floating system cable stayed bridge structure.
Background technology
Using A, H, the queen post bridge towers such as Y shape that fall more than conventional Cable-Stayed Bridge Structure, bridge tower consumption is big, pylon foundation scale
Greatly, long construction period.Meanwhile, pair cable-stayed bridge wider with bridge floor, the landscape effect using the formation of conventional bridge tower form is also bad.
In addition, for bridge vertical section is relatively low, bridge floor is wider and needs the cable-stayed bridge of rotator construction, it is double using conventional Cable-Stayed Bridge Structure
Pillar bridge tower can not realize that bridge tower lower king-post strut collapses to base position so as to the function of swivel in time.
The content of the invention
The purpose of this utility model seeks to solve the bridge tower architecture basics for the prior art mentioned in above-mentioned background technology
Scale is big, long construction period, there is provided a kind of half floating system of only post wide cut rachis face is oblique the problem of can not realize bridge rotating
Draw bridge structure.
The technical solution of the utility model is：A kind of only floating system cable stayed bridge structure of post wide cut rachis face half, including
Girder and the pier stud for support girder below girder；Described pier stud includes the side being supported in girder end bay beam body
Across pier stud and in being supported in girder on bridge body across pier stud；In described across be provided with pier stud vertically through master
The king-post of beam, it is characterised in that：Described king-post is that vertically can produce phase with girder in the vertical direction through girder
To the single column structure of displacement, the part of king-post through girder passes through dismountable wind-resistant support and girder in the horizontal direction
Connection, the lower end of king-post be fixed in across the upper end of pier stud, king-post be located at tower body above girder along bridge to both sides be provided with
Double rope faces suspension cable；Described double rope face suspension cable upper ends are anchored at king-post sidepiece, and anchoring lower ends are on girder.
Further described girder offers the through hole passed through for king-post on the centre position along direction across bridge direction.
Further described king-post, which is located on the tower body below girder, is provided with support beam；Described support beam is along horizontal stroke
Bridge protrudes from the horizontal beam body of king-post side to direction, and the upper end of support beam is supported on the bottom of girder.
Advantage of the present utility model has：1st, king-post and suspension cable are arranged in deck centre anchor-hold area scope, it is to avoid
Frozen in the influence and winter suspension cable to headroom of the driving a vehicle ice slush of formation of suspension cable drops security incident caused by driveway,
Bridge tower is that not contact bridge tower with bridge in a lateral direction be single pillar structure to only tower structure, basic small scale, on horizontal direction with
Bridge is connected by wind-resistant support, easily realizes that bridge beam body is turned；
2nd, the utility model is applied to Cable-Stayed Bridge Structure of the main span span between 150~350m, and be particularly suitable for use in bridge floor
Wider, rotator construction half floating system cable stayed bridge；
3rd, only cylindricality bridge tower of the present utility model, simple in construction, greatly optimizes bridge tower consumption, economy is preferably same
When, improve Bridge Landscape.

Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Such as Fig. 1~2, a kind of only floating system cable stayed bridge structure of post wide cut rachis face half, including girder 1, the present embodiment
Girder 1 include end bay beam body and middle bridge body, beam body is steel box girder, is supported by double rope faces suspension cable 5.End bay beam body
Lower section be provided with end bay pier stud 4, end bay pier stud 4 is supported on to be provided with below the lower surface of end bay beam body, middle bridge body
Across pier stud 3.The end bay pier stud 4 of the present embodiment is the supporting construction of armored concrete across pier stud 3 with.
In the upper end of pier stud 3 is provided with king-post 2, the king-post 2 of the present embodiment is that " 1 " font being arranged on girder 1 is only
Tower structure, is only cylindricality armored concrete rectangle hollow structure, the lower end of king-post 2 through the through hole on girder 1, in being anchored at across
The upper end of pier stud 3.King-post 2 be located at the tower body of the top of girder 1 along bridge to both sides be provided with double rope faces suspension cable 5, double rope faces are oblique
The upper end of drag-line 5 is anchored at the sidepiece of king-post 2, and anchoring lower ends are on the center line of girder 1.Suspension cable 5 is located at the centre position of bridge deck, this
Suspension cable 5, which is hung ice and dropped, when the arrangement of sample can avoid winter day cold influences the current vehicle in lower section.
Girder 1 offers the through hole passed through for king-post 2 on the centre position along direction across bridge direction.The king-post 2 of the present embodiment
Part tower body through girder 1 is connected by wind-resistant support with girder 1, is in the horizontal direction fixation between king-post 2 and girder 1
Structure, king-post 2 is not connected to the in the vertical direction of girder 1, and king-post 2 can produce relative displacement with the in the vertical direction of girder 1, main
Beam 1 is half form floated, and king-post 2 is connected by wind-resistant support in the horizontal with girder 1, is easy to the horizontal swing of girder 1 to apply
Work, is easy to the Horizontal Swing Construction of girder 1.
