Description
Technical field
The utility model belongs to the technical field of suspension bridge, and in particular to a kind of half-through suspension bridge.
Background technique
Suspension bridge is across a kind of maximum works of ability, under normal circumstances, suspension bridge by anchorage, bridge tower, main push-towing rope, hang
Bar or column, five part of bridge deck (girder) composition.It is outstanding to be divided into base-supporting according to main push-towing rope, the positional relationship of girder or Path of Force Transfer
Cable bridge or deck type suspension bridge (anti-suspension bridge), the suspension bridge of ordinary meaning refer to that base-supporting suspension bridge, deck type suspension bridge also have
Some successful stories, but it is rare.Base-supporting suspension bridge mainly includes earth anchor base-supporting suspension bridge (such as Fig. 1) and holds under anchor
The characteristics of formula suspension bridge (such as Fig. 2), base-supporting suspension bridge is that girder is located at below main push-towing rope, and girder is connect by sunpender with main push-towing rope,
Sunpender bears pulling force at this time, as girder elastic bearing.Main push-towing rope bears steeve tension effect, and both ends are anchored in earth anchor or beam-ends.
It is balanced from the tension of main cable T component in the horizontal direction of anchor base-supporting suspension bridge by the axis pressure P of beam-ends.Deck type suspension bridge master
It to include earth anchor deck type suspension bridge (such as Fig. 3) and from anchor deck type suspension bridge (such as Fig. 4), the characteristics of deck type suspension bridge is main
For beam above main push-towing rope, column is the elastic bearing of girder, and power is transmitted to main push-towing rope by column by girder, and column bears pressure work at this time
With.Main push-towing rope is still under pulling force effect, and both ends are anchored in earth anchor, can also be anchored in beam-ends.
Although it is vertical however, above-mentioned base-supporting suspension bridge and deck type suspension bridge all have biggish span ability
It is all lower to rigidity and lateral stiffness, although can be improved in the method that span centre adds center button, improved limitation,
Rigidity is too low to cause structure to be easy to motivate in low-frequency range, and comfort level of driving a vehicle and degree of safety reduce.
Summary of the invention
The purpose of this utility model be exactly in order to solve deficiency existing for above-mentioned background technique, provide a kind of rigidity greatly, hold
The big half-through suspension bridge of loading capability.
A kind of in order to achieve the above purposes, the technical solution adopted by the utility model is: half-through suspension bridge, including girder,
It is respectively provided with to bridge tower, the direction across bridge two sides of the bridge tower are arranged at intervals with along the master along bridge to extension on the girder along bridge
Main push-towing rope is divided into upper cable and lower cable, is arranged between the upper cable and the top end face of girder by cable, the centre that the girder is located at main push-towing rope
Have several along to spaced apart sunpender, be provided between the lower cable and the bottom face of girder along bridge several along bridge to
Spaced apart column；The intersection of the girder and main push-towing rope consolidation.
Preferably, the both ends of the main push-towing rope are anchored with positioned at ipsilateral end of main beam respectively.
Preferably, the suitable bridge of the girder is to being provided with earth anchor on the outside of both ends, and the two of the main push-towing rope
End is anchored with earth anchor respectively.
Preferably, main pier is provided with immediately below the bridge tower.
Preferably, the suitable bridge of the girder is provided with abutment pier to both ends bottom.
The beneficial effects of the utility model are:
First, the half-through suspension bridge middle girder of the utility model is located among main push-towing rope, main push-towing rope and girder are solid in intersection
Knot, main push-towing rope and girder have an identical freedom degree in point of intersection, and external force can be directly transmitted to main push-towing rope by when such main beam stress, without
By sunpender or column indirect transfer, sunpender or column are mainly to bear based on vertical load, since main push-towing rope rigidity is larger, especially
It is lateral, the transversely deforming of girder considerably increases suspension bridge rigidity by main push-towing rope elastic restraint, thus in direction across bridge, improves
Safety and road-ability.
Second, the half-through suspension bridge of the utility model can reduce bridge tower height, reduce construction cost, and can
Bridge tower rigidity is increased, construction also becomes convenient.
