Description
Technical field
This utility model belong to a kind of suspension bridge and in particular to a kind of interior from anchor suspension bridge.
Background technology
Suspension bridge structure has that stress performance is good, span ability big, lightly attractive in appearance, shock resistance is strong, version is various
And good to landform adaptability the features such as, many cross over the hindrance to traffics such as great rivers, high mountain gorge, bay harbour when,
Often as first-selected bridge type.Therefore, people also have devised multiple Suspension bridge structure.As Chinese Patent Application No. is
201510012845.7 disclose a kind of suspension bridge of high torsional rigidity, and including girder, Sarasota, main push-towing rope and suspension rod, main push-towing rope is one
Bar and be located at girder longitudinal center facade, suspension rod be distributed in girder both lateral sides for by main push-towing rope suspend in midair girder so that main push-towing rope,
Suspension rod and girder form the structure that cross section is spatial triangle；This utility model utilizes the stability of triangle, forms one
Similar to triangle box-beam structure, fundamentally improve the overall torsional rigidity of suspension bridge and reverse shake frequency, directly improve quiet wind
The critical wind velocity of lower torsional buckling, it is also possible to increase reverse shake frequency and the vertical ratio shaking frequency, thus improve electric shock
Critical wind velocity, also ensure that compared with large span suspension bridge safety；And, do not increase existing suspension bridge material and
Cost, and in fact, main push-towing rope is one, cross-sectional area can be increased, and increase suspension rod quantity and cross-sectional area, increase further and turn round
Turn rigidity.And for example Chinese Patent Application No. discloses a kind of self-anchored suspension bridge for 200920043292.1, including Sarasota basis,
Sarasota, cable saddle, stiff girder, main push-towing rope and suspension rod, the steel pipe being provided with concrete perfusion in empty steel pipe in described stiff girder and being formed
Concrete combined component.Using concrete filled steel tube stiff girder, cost not only can be reduced, and easy construction, can substantially add
Fast construction speed.For another example Chinese Patent Application No. discloses a kind of bridge structure for 201120102496.5, includes runway
Beam, bridge tower, anchorage, weight cable, is characterized in that, weight cable is combined by a main rope and Duo Gen rope, opens from Sarasota
Begin, keep at a certain distance away and several ropes are separated from weight cable, be connected with track beam, the secondary rope on weight cable separates
Place is provided with a point cable device.Weight cable is made up of secondary rope and main rope, and with fixture combination together；Cable utensil is divided to have secondary rope from load-bearing
The inner chamber of main push-towing rope separation shape, and have clamp device, can be fixed on weight cable；Structure of the present utility model can optimize
The stress of suspension bridge weight cable, saves material.
But the earth anchored suspension bridge in generally conventional formula, needs to build bulky anchorage to anchor main push-towing rope, this is just
Cause the place in geological condition difference, the foundation engineering amount of anchorage structures is very big, often becomes the difficult point of engineering；Ground anchor type hangs
Cable bridge anchorage and Anchor Foundation occupy the considerable part of construction costs, become the important side of impact Suspension bridge structure economy
Face；In urban area or tourist district, build bulky anchorage, environmental beauty also can be had a negative impact.
Utility model content
For the problems referred to above, this utility model provides in one kind from anchor suspension bridge, by setting up water at Sarasota two ends
Flat bar and batter post, make main push-towing rope bypass Sarasota top cable saddle, horizontal boom end steering block I, Sarasota bottom steering block II, batter post successively
It is fixed on girder after bottom steering block III.Act on the load on girder and follow following Path of Force Transfer：Girder → hoist cable
→ main push-towing rope → bridge tower → horizon bar → Sarasota basis → inclined column foundation → wraparound girder.Cable is bypassed Sarasota basis, reduces
The foundation pressure of Sarasota；Cable is fixed on girder, increases girder axle power, improves suspension bridge wind resistance；Due to setting up
Batter post is thus increase the lateral rigidity of tower.Compared with earth anchor suspension bridge, eliminate bulky anchorage；With from anchor suspension bridge
Compare, the interior span being far longer than from anchor suspension bridge from anchor suspended span, can reach or exceed earth anchor suspension bridge.
This utility model takes technical scheme below to realize above-mentioned purpose：
From anchor suspension bridge in a kind of, mainly by main push-towing rope, hoist cable, Sarasota, batter post, horizon bar, girder and girder auxiliary pier group
Become；Described hoist cable is evenly arranged between main push-towing rope and girder；Described Sarasota is located at the two ends of girder；Described batter post and water
Flat bar is separately positioned on the both sides of Sarasota, and has a common end points, and that is, the end of batter post and horizon bar are in same water
On horizontal line, end points is located at the midpoint of Sarasota；It is provided with steering block I in the end of horizon bar；It is provided with cable saddle, Sarasota at the top of Sarasota
Bottom poured basis II and be provided with steering block II；Pour basis I in the bottom of batter post and be provided with steering block III；Described
Girder auxiliary pier be located at the two ends of girder, and the top braces girder of girder auxiliary pier, bottom is in Sarasota bottom and tiltedly
Between column bottom；The end of described main push-towing rope bypasses the cable saddle at Sarasota top, the steering block I of horizontal boom end, Sarasota bottom successively
It is fixedly mounted on girder and girder auxiliary pier junction after the steering block II in portion, the bottom steering block III of batter post.
Further illustrate, described main push-towing rope is provided with scattered cable saddle around at basic I.
Further illustrate, about described Sarasota top, main push-towing rope within angle α become with Sarasota in two ends is equal and is less than 180 °.
Further illustrate, described horizon bar upper and lower ends main push-towing rope is equal with the inner clip angle beta that horizon bar is formed and is less than
180°.
Further illustrate, described batter post and/or horizon bar adopt steel construction lattice column form or steel case or coagulation
Native box is made.During using steel construction lattice column form or steel case, can effectively reduce horizon bar and batter post deadweight.
In this utility model, when geological state is preferable, can directly adopt shallow foundation；When geological state is general, in batter post
Bottom batter piling；When geological state is poor, the stake being squeezed into or sunk to by many roots in soil and the cushion cap institute of connection stake top need to be made
The basis constituting；
In this utility model, main push-towing rope is the main supporting member of this system, is primarily subjected to pulling force；Hoist cable plays connection master
Beam and the effect of main push-towing rope, only transmit the component of load, and the load such as girder, bridge deck and mobile load passes to main push-towing rope by hoist cable；Rope
Tower acts the effect supporting main push-towing rope, is primarily subjected to pressure；Suo Li is passed to Sarasota and batter post by horizon bar, and power is reached by Sarasota and batter post
