Description
Technical field
The invention belongs to science of bridge building antidetonation and cushion technique field, relate to a kind of landscape configuration
Presstressed reinforcing steel bridge pier, arranges rubber layer simultaneously, thus realizes geological process between bridge pier and basis
The Self-resetting of lower bridge pier and power consumption function.This invention is with low cost, and anti-seismic performance highlights, construction
Simplicity, effective restrainer, there is good development prospect.
Background technology
In recent years, as the people that improve of people's living standard also get over for the requirement of antidetonation shock attenuation
Coming higher, since especially 2008 Wenchuan earthquakes, the various disasters that earthquake causes are increasingly
Cause the attention of people, not only to building a building, the Architectural Equipments such as bridge are also required that more
Come higher.In Wenchuan earthquake in 2008, hundreds of bridge blocks destroy in earthquake, its
Failure mode mainly have bridge pier fracture beam destroy or directly fall beam destroy.After this is to calamity
The serious impact that rescue causes, brings huge damage more to the safe property of the country and people
Lose.Therefore the antidetonation shock attenuation performance researching and developing bridge has great importance.
The antidetonation of current bridge pier essentially consists in and increases the connection that depth of foundation strengthens basis and ground,
Make basis firmer, the damage of bridge pier during to reduce coming earthquake.But this mode is for greatly
Effect during type earthquake is little, there is no one at present and effectively prevents from destroying under bridge pier geological process
Antiseismic and shock-absorbing installation, the current shockproof effect for bridge pier inconspicuous in a word.The present invention carries
Go out a kind of pier column to separate with basis, and configure the connected mode of transversely prestressed bars, it is ensured that just
Meet load requirement under normal use state, certain recovery and power consumption work(are provided during coming earthquake
Can, it is achieved reduce the antidetonation shock attenuation requirement that bridge pier destroys；In addition, the one that this invention proposes can
Change landscape configuration presstressed reinforcing steel Self-resetting power consumption bridge pier under big shake effect if it occur that destroy,
The replacing of bridge pier can be carried out to it so that easier in terms of the bridge reparation after shake.This
The bright deficiency that can overcome above-mentioned bridge pier earthquake resistant construction, provides more multifarious skill for bridge earthquake resistance
Art is supported, has great practical meaning in engineering.
Content of the invention
The present invention provides a kind of replaceable landscape configuration presstressed reinforcing steel Self-resetting power consumption bridge pier, invention
Purpose is under geological process the Self-resetting utilizing the restoring force of transversely prestressed bars to realize bridge pier
Function；Meanwhile, filled rubber layer between bridge pier and basis, it is achieved the clamping function of bridge pier reality
Bridge pier power consumption under existing geological process；The other present invention provides a kind of replaceable landscape configuration prestressing force
Muscle Self-resetting power consumption bridge pier, can realize the quick-replaceable reparation after eaerthquake damage.
To achieve these goals, this invention takes following technical scheme.
The one replaceable landscape configuration presstressed reinforcing steel Self-resetting power consumption bridge pier of the present invention, it includes
The 4th, prestressed reinforced concrete post the 1st, longitudinal prestressing muscle the 2nd, common stirrup the 3rd, rubber layer adds
Strong stirrup the 5th, transversely prestressed bars the 6th, anchorage the 7th, basis 8.Prestressed reinforced concrete post 1
Interior configuration longitudinal prestressing muscle 2 and common stirrup 3, at the position that transversely prestressed bars 6 passes through
Arrange and strengthen stirrup 5；Prestressed reinforced concrete post 1 is placed in band reeded basic 8,
Prestressed reinforced concrete post 1 and basis 8 are by passing across prestressed reinforced concrete post 1
Transversely prestressed bars 6 connects, between filled rubber layer 4.
Prestressed reinforced concrete post 1 and basis 8 employing high-strength concrete.
Reinforcement stirrup 5 in prestressed reinforced concrete post 1 is arranged in transversely prestressed bars 6 and wears
The position crossed.
Transversely prestressed bars 6 is non-bending steel cable, prestressed reinforced concrete post 1 horizontal
The position reserving hole channel that presstressed reinforcing steel 6 passes through, uses post stretching stretch-draw non-bending steel cable.
Prestressed reinforced concrete post 1 is prefabricated, and construction uses fabricated construction.
The function of the present invention is as follows:
Transversely prestressed bars utilizes its restoring force to realize the Self-resetting function of bridge pier；On the basis of recessed
Groove is as the positioner of bridge pier, and between bridge pier and basis, filled rubber layer carries out damping power consumption；
Bridge pier separates with basis, and transversely prestressed bars uses post-tensioned construction to be easy to the replaceable of bridge pier,
Thus finally realize the Self-resetting of bridge pier, power consumption, replaceable function.
Transversely prestressed bars is non-bending steel cable, utilizes its restoring force to realize in advance should in earthquake
Power reinforced column position move after reset.Transversely prestressed bars uses post-tensioned construction,
Reserving hole channel in prestressed reinforced concrete post, it is simple to the replacing of prestressed reinforced concrete post.
Filled rubber layer between prestressed reinforced concrete post and basis, rubber layer in earthquake
Extruding etc. realize the power consumption to prestressed reinforced concrete post, reduce deformed bar in earthquake and mix
The destruction of solidifying earth pillar.
Prestressed reinforced concrete post is positioned in the basis arranging draw-in groove in advance, fills out between the two
Filling rubber layer, if big earthquake centre prestressed reinforced concrete post occurs to destroy, girder does not falls off,
Support girder can be set up and ensure the quick-replaceable of prestressed reinforced concrete post, it is achieved bridge
Quick reparation.
Compared with prior art, advantages of the present invention is as follows:
1) transversely prestressed bars in the present invention, it is possible to achieve the Self-resetting function in earthquake of bridge pier,
Add the flexibility of bridge pier, improve the ductility that earthquake Bridge destroys.
2) in the present invention, the rubber layer between prestressing force bridge pier and basis realizes the consumption in earthquake to bridge pier
Can, the favourable damping power consumption realizing girder construction.
3) present invention proposes the structure that a kind of novel bridge pier separates with basis, it is achieved bridge pier can be more
Change, such that it is able to realize the quick reparation after bridge collapse.
4) present invention needs cost relatively low, can be achieved with the high ductility of bridge pier and the destruction side consumed energy
Formula, and realize the replaceable of bridge pier when repairing, effectively reduce financial cost, have relatively
Big practical meaning in engineering.
