Abstract
The utility model relates to a large-displacement inhaul cable type expansion joint device with symmetric movable toothed plates. An inhaul-cable-type double-curved-surface spherical support is arranged below the movable toothed plates and connected with the movable toothed plates in an anchoring mode through a stainless steel plate. The movable toothed plates are partitioned into several parts to be connected with the stainless steel plate on the lower portion in an anchoring mode, and it is guaranteed that relative vertical rotating of beam bodies on two sides is achieved under the earthquake action and the toothed plates will not crack. Due to the adoption of the inhaul-cable-type double-curved-surface spherical support and an inhaul cable, when a strong earthquake happens, longitudinal, transverse and vertical displacement and rotating angles can be effectively restrained, temperature changes and vehicle impact loads under normal using conditions can be achieved, beam falling is controlled under the limit state of the strong earthquake, shock absorption and limiting are achieved, and after-earthquake self-return ability of the large-displacement inhaul cable type expansion joint device can be achieved through performance of the large-displacement inhaul cable type expansion joint device. The large-displacement inhaul cable type expansion joint device with the symmetric movable toothed plates plays a good role in shock absorption limiting and damping energy dissipation during the earthquake, and therefore the wide application of the shock insulation and resistance design method is made possible.
Description
Technical field
The utility model relates to a kind of bridge expansion joint installation, relates in particular to a kind of large displacement drag-line of symmetrical swing tooth plate bridge expansion joint installation with higher anti-seismic performance.
Background technology
Tradition bridge extension joint generally comprises: be positioned at the first beam body, the second beam body of bridge telescopic construction seam both sides and be separately positioned on the first beam body and the second beam body on swing tooth plate, fixed tooth plate, swing tooth plate is placed on bridge telescopic construction seam as transverse joint plate, and swing tooth plate, fixed tooth plate are respectively provided with broach space in relative separately end staggered.In the time of coming earthquake, because the vibration of two beam bodies causes the movement at shrinkage joint, and the length travel at current traditional shrinkage joint is very little, and transverse shifting and relative rotation are less.In passing domestic and international each violent earthquake, the impact events of fall beam and mutual beam body occurs often, causes serious casualties and economic loss.How could effectively guarantee that bridge can also use safely after shake, should take which type of antishock device to avoid the generation of above-mentioned situation.As the tie between Liang Yuliang---shrinkage joint, be more and more subject to people's attention.We need to find a kind of stretching device that also can finely play a role in the time of earthquake.
The shortcoming of tradition comb plate stretching device: 1,, when large shake comes temporarily, do not possess laterally large displacement capacity, often occur the phenomenons such as broach fracture.2, in the time of beam body generation lateral rotation, movable comb tooth plate there will be " nose " phenomenon, has a strong impact on traffic safety and smooth-going, greatly reduces comb plate intensity, rigidity and impact resistance.3, when bridge is under vehicular load and warm change effect, beam body produces deflection deformation and can produce and upwarp at beam-ends, finally causes device to damage.4, movable comb tooth plate is placed on beam body end face, in the time of coming earthquake, can vertically move along with beam body, but seismic direction has randomness, and longitudinally, laterally, vertically and respectively to rotation, traditional stretching device can not meet above-mentioned requirements.5, between transverse joint plate and swing tooth plate, be connected with rotating hinge, in the time that beam body has a vertical displacement, can, by transverse joint plate jack-up, occur " nose ", form " Eight characters shape " on beam body top, cause transverse joint plate and swing tooth plate to come to nothing.
In view of all deficiencies that above-mentioned comb plate shrinkage joint exists, therefore, be necessary the bridge expanssion joint in prior art to be improved further.We on the basis of comb plate shrinkage joint, hyperboloid spherical bearing, the large displacement drag-line of a kind of symmetrical swing tooth plate of design forming expansion gap device.
Summary of the invention
The purpose of this utility model be to provide a kind of can operative constraint severe earthquake action under relative displacement and corner between shrinkage joint swing tooth plate, fixed tooth plate, buffering front and rear beam body collides mutually, consume macroseism energy, can effectively control Luo Liang and beam body and damage, reduce the large displacement drag-line of the symmetrical swing tooth plate expansion gap device that Bridges During Earthquake shrinkage joint is destroyed.
