Description
Technical field
Bridge is the utility model is related to, more particularly to a kind of board-like suspension rod wind resistance guiding device.
Background technology
Rigid hanger and flexible hoist cable are two kinds of conventional structure types of middle half/through arch bridge suspender.Rigid hanger generally with
Structural steel is material, using rectangle, H-shaped, circle, solid board-like uiform section form.Then generally use is high-strength parallel for flexible hoist cable
Steel wire or steel hinge line are generally circular as structural material, profile.The high tensile steel wire material yield used due to flexible hoist cable
Intensity is far above the structural steel that rigid hanger uses, therefore rigid hanger sectional area is substantially high under identical design axle power effect
In the sectional area of flexible hoist cable, so that the Fatigue Stress Amplitude of rigid hanger is significantly lower than flexible hoist cable.Further, since flexibility is hung
Rustling sound body generally as PE sheaths inside, belong to concealed work, daily anti-corrosion check it is difficult, therefore, during arch bridge military service,
Flexible hoist cable needs to regularly replace, and on the one hand generates higher operation maintenance expense, on the other hand, because flexible hoist cable is changed
During need close traffic, usually come at larger social influence.And master of the service life of rigid hanger generally with full-bridge
It is consistent to want supporting member, is not required to change during use, therefore, has larger use advantage.
Rigid hanger has the advantage for being not required to change in use, but because the wind resistance of rigid hanger is poor,
At this stage, using not universal in middle lower bearing arch bridge.For example, 2006, China southeastern coast main span 300m Fo Shandong
Flat bridge H suspension rods just generate significantly twisting vibration under wind effect and result in more boom heel fractures, cause tight
The Socie-economic loss of weight；The square-section suspension rod of main span 336m Beijing-Shanghai express railway Nanjing Foundations of Dashengguan Changjiang River Bridge is although take
The aerodynamic configuration design measure of surrounding corner cut, still there occurs significantly wind-induced vibration after real bridge crane bar installation, finally adopt
Improve its wind resistance with mechanical damping measure.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of board-like suspension rod wind resistance guiding device, to be effectively improved
The aerodynamic configuration of board-like suspension rod, its wind resistance is improved, give full play to the advantage of rigid hanger.
Technical scheme is as follows used by the utility model solves its technical problem：
Board-like suspension rod wind resistance guiding device of the present utility model, including board-like suspension rod, board-like suspension rod have on cross section
Four limbs to interlock in cross, it is characterized in that：The board-like suspension rod is provided with deflector, each water conservancy diversion outside four limbs
Plate by board-like length of boom direction spaced connecting elements be fixedly mounted on corresponding on limbs；Deflector plate face
It is straight, and extend along the length direction of board-like suspension rod.
The beneficial effects of the utility model are to improve the aerodynamic configuration of board-like suspension rod, improve its wind resistance, give full play to
The advantage of rigid hanger；Guiding device is connected with board-like suspension rod by pin plate, and regular maintenance expense is low, does not bring significant cost
Increase.
Brief description of the drawings
This specification includes the following accompanying drawing of width two：
Fig. 1 is the front view (part) of the board-like suspension rod wind resistance guiding device of the utility model；
Fig. 2 is the sectional view of the line A-A along Fig. 1；
Component and corresponding mark are shown in figure：Board-like suspension rod 10, deflector 11, intermediate plate 12.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Reference picture 1, board-like suspension rod have on cross section in cross interlock four limbs, in being mainly used under hold
Among formula arch bridge, mainly arranged in upright plane, connect arch rib and bridge deck, bridge deck load is delivered to arch rib.Ginseng
According to Fig. 1 and Fig. 2, the board-like suspension rod 10 is provided with deflector 11 outside four limbs, and each deflector 11 board-like by hanging
Spaced connecting elements is fixedly mounted on corresponding limbs on the length direction of bar 10.The plate face of deflector 11 is straight, and edge
The length direction extension of board-like suspension rod 10.The setting of deflector 11 can be effectively improved the aerodynamic configuration of board-like suspension rod 10, improve it
Wind resistance, give full play to the advantage of rigid hanger.
Generally, the length of deflector 11 and the equal length of board-like suspension rod 10.
Reference picture 2, the connecting elements are the C-shaped intermediate plate 12 in cross section, and the axle portion of intermediate plate 12 passes through bolt and water conservancy diversion
Plate 11 is detachably connected, and the opening portion of intermediate plate 12 is detachably connected by bolt and limbs.
Setting and the mounting means of deflector 11 are further illustrated with an engineering example below.
Reference picture 2, board-like suspension rod 10 are cross solid section form, and overall dimension is 300 × 300mm, along section four
The strip deflector 11 that four sectional dimensions are 100mm × 10mm, the longitudinal length and plate of deflector 11 are arranged outside individual limbs
Formula suspension rod 10 is identical, and the vertical clearance between any deflector 11 and corresponding limbs is 50mm.
It is connected between deflector 11 and board-like suspension rod 10 by the intermediate plate 12 of longitudinal spaced set, between adjacent clips 12
Longitudinal pitch be 1000mm, it is ensured that 10 stable are connected between deflector 11 and board-like suspension rod.Intermediate plate 12 is by for thickness 4mm, width
Degree 40mm strip steel disc bending forms, and be C-shaped cross section, and clear distance is identical with correspondence limbs thickness of slab between opening portion.
Some principles of the utility model board-like suspension rod wind resistance guiding device described above that simply explains through diagrams, it is not
The utility model is confined in shown and described concrete structure and the scope of application, therefore every phase for being possible to be utilized
It should change and equivalent, belong to the apllied the scope of the claims of the utility model.
