Description
Technical field
The utility model is related to a kind of high antiskid suspension bridge saddle, belongs to bridge structure technical field.
Background technology
In the structure of suspension bridge, cable saddle is arranged at the top of king-tower and end bay turning point, main push-towing rope to be fixed simultaneously
Support.The dynamic and static load of bridge floor passes sequentially through hoist cable and main push-towing rope passes to cable saddle, then passes to king-tower by cable saddle or turn to support
Frame.Due to the functional characteristic of cable saddle, it is desirable to during one's term of military service without relative slip between cable saddle and main push-towing rope.In actual engineer applied mistake
Cheng Zhong, during static load, the main push-towing rope horizontal force of cable saddle both sides is of substantially equal, substantially without relative tendency toward sliding between main push-towing rope and cable saddle；It is dynamic
During load, larger difference occurs in the main push-towing rope horizontal force of cable saddle both sides, so as to cause main push-towing rope to have tendency toward sliding in cable saddle.If occurring
Relative to slide, will wear and tear main push-towing rope steel wire, the security of crisis bridge structure.
Particularly, in recent years, multi-span suspension bridges are developed in China, compared with two traditional tower suspension bridges, multitower
Suspension bridge adds middle bridge tower, in the presence of unsymmetrical loading, and the tension force difference of main push-towing rope is larger in tower top saddle, and main push-towing rope exists
It is easier to slide in saddle.It is right in multi-span suspension bridges calculating due to the mechanical characteristic of multi-span suspension bridges " middle tower effect "
The checking computations of main push-towing rope antiskid safety are a main checking computations contents, and especially in rigid tower scheme, main push-towing rope antiskid security control rises
Come relatively difficult.If but by the rational design of structural system and to the improvement in the type of attachment of main push-towing rope and saddle, to carry
High main push-towing rope resistant slide security performance, so as to solve problem so that scope is more extensive in the selection of centering turriform formula, can be more
Fully play out the advantage of multi-span suspension bridges.Therefore the research to the resistant slide safety of main push-towing rope and saddle turns into multi-span suspension bridges
One of main research.Domestic and foreign scholars have also carried out numerous researchs to this, are concentrated mainly on the power of multi-span suspension bridges structure
Scholarship and moral conduct is the aspect of friction behavior two with main push-towing rope saddle.
In addition, in work progress, because strand is usually vertically to be separated by cantilever dividing plate in saddle, rope in each separate layer
Vertical extruding force is smaller between stock, the phenomenon cut in and out often occurs, it is impossible to effectively fix each strand.And the steel wire in strand
Contacted between vertical demarcation strip on cross section for point, construction period steel wire is constantly slided up and down, damage the anti-corrosion protection of steel wire
Layer, is unfavorable for strand anti-corrosion.
The vertical bridge of suspension bridge during one's term of military service between main push-towing rope and saddle is to relative slip, and erecting between construction period strand and saddle
The significant design and Construction control content of suspension bridge to relative slip, the control that to be also suspension bridge develop to multitower direction because
Element.Therefore, in the urgent need to a kind of high antiskid suspension bridge saddle, so that in construction period and during one's term of military service, main push-towing rope can be effective against
Occur Relative sliding with cable saddle, improve the security of structure.
The content of the invention
The purpose of this utility model is that solve above-mentioned the deficiencies in the prior art and problem resists there is provided a kind of height
Sliding suspension bridge saddle.
A kind of high antiskid suspension bridge saddle that the utility model is provided, including saddle and the strand passed therethrough, saddle
It is made up of base, end plate, side plate, cover plate etc., strand horizontal slice in saddle, there is demarcation strip, each layer demarcation strip between every layer
Upper and lower side, which makes, the groove corresponding with strand, and the corresponding groove area defined of upper and lower layer demarcation strip is slightly larger than rope
The cross section of stock, lower portion gap has flexible metaltape filling, and the upper flexible rim strip of portion gap is filled, and side plate interior sides have vertical
Recess on projection, correspondence demarcation strip；There is bolt hole demarcation strip both sides, so that after demarcation strip penetrates bolt, tightening nuts are solid
It is fixed.This programme is by setting horizontal splitter plate, it is to avoid during using current vertical demarcation strip, and extruding force is in the construction time in strand
Between the phenomenon that cuts in and out, it is ensured that do not slided in construction period；By wrapping up soft metal around strand, it is to avoid strand
Contacted on cross section with the point of demarcation strip, improve the antiseptic power of steel wire；Soft metal improves steel wire to the parcel of steel wire
Slide coefficient, improve stability against sliding.Cushion band provides extruding force to strand, except providing support to upper strata demarcation strip
Outside power, mainly the antiskid frictional force of strand can be provided.
Further, cross section of each strand of main push-towing rope in saddle is into regular hexagon.This is for the ease of composition
The close circle in main push-towing rope section.
The groove of the upper and lower side of described demarcation strip is semicircle.This is primarily to be easy to manufacture.
Described strand is steel strand wires, and the material of described flexible metaltape is tin., can be direct in the suspension bridge of small span
Using steel strand wires as strand, structural cost is reduced.
The demarcation strip bolt hole position on described upper strata is corresponding with lower floor, and quantity is not more than lower floor.
The demarcation strip lower surface of described centre has an antiskid groove, and there is an anti-skidding raised line upper surface, corresponding antiskid groove with
Anti-skidding raised line coordinates closely connected.Primarily to relative between preventing each demarcation strip slide laterally.
Compared with prior art, the utility model has the advantages that：Strand is not present mutually extruding and asked in cable saddle
Topic；The lifting weight saving of saddle, constructing operation is simple, low manufacture cost；The anti-fatigue performance of main push-towing rope, and antiskid can be improved
Dependable performance, improves the security of structure.
