Abstract

The utility model relates to a stay rope-roll shaft type expansion joint device. A swing tooth plate is fixed on a first beam through a roll shaft and can rotate freely. A fixed tooth plate is fixed on a second beam in a joggling manner, the swing tooth plate and the fixed tooth plate are overlapped in a comb tooth shape manner, and a rubber seal and a stay rope device are mounted below an expansion joint. When the first beam and the second beam have vertical displacement difference, the swing tooth plate can rotate to keep a bridge deck smooth and continuous. The fixed tooth plate is fixed on the second beam by means of joggling. When a strong earthquake happens and large lateral displacement happens between the beams, the joggled part can slide laterally to prevent breakage of the tooth plates. When the swing tooth plate gets close to the fixed tooth plate, a sealing rubber pad can buffer acting face caused by mutual impact between the beams. The stay rope-roll shaft type expansion joint device can meet the requirements on longitudinal, lateral, vertical and omnidirectional rotation under earthquake action, thereby having high earthquake resistance. The stay rope-roll shaft type expansion joint device is simple in structure, stable in earthquake resistance, convenient to produce and use and safe.

Description

Drag-line-roller shaft type expansion gap device
Technical field
The utility model relates to a kind of bridge expansion joint installation, relates in particular to a kind of higher anti-seismic performance drag-line-roller shaft type expansion gap device that has.
Background technology
Traditional axle expansion joint installation of girder 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.When coming earthquake, because the vibration of two beam bodies causes the movement at shrinkage joint.In passing domestic and international each violent earthquake, because the length travel at traditional shrinkage joint is very little, transverse shifting and relative rotation are less, and it is seriously damaged.Tradition comb plate shrinkage joint can not meet bridge earthquake resistance demand, and we need to find a kind of stretching device that also can finely play a role when earthquake.
The shortcoming of tradition comb plate stretching device: 1. next interim when large shake, do not possess laterally large displacement capacity, often there is the phenomenons such as broach fracture.2. 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.3. movable comb tooth plate is placed on beam body end face, when coming earthquake, can vertically move along with beam body, yet seismic direction has randomness, longitudinally, laterally, vertical and each to rotation, traditional stretching device can not meet above-mentioned requirements.4. between transverse joint plate and swing tooth plate, with rotating hinge, be connected, when beam body has a vertical displacement, transverse joint plate jack-up can be occurred " nose ", on beam body top, form " Eight characters shape ", cause transverse joint plate and swing tooth plate to come to nothing.5. between the first beam body and the second beam body, lack coupling beam device, under strong earthquake motion effect, beam easily falls.
In view of the deficiency at above traditional shrinkage joint, be necessary existing bridge expanssion joint technology to improve.The utility model designs a kind of drag-line-roller shaft type expansion gap device with higher anti-seismic performance on the basis at traditional broach shrinkage joint.
Summary of the invention
The purpose of this utility model is to provide a kind of larger displacement of generation of locating longitudinally, laterally and vertically allow flexible under earthquake motion effect, between fixed tooth plate and swing tooth plate, can there is larger corner, can effectively control Luo Liang and beam body and damage, reduce drag-line-roller shaft type expansion gap device that Bridges During Earthquake expansion gap device destroys.
For reaching above object, drag-line-roller shaft type the expansion gap device the utility model proposes, comprise swing tooth plate 1, fixed tooth plate 2, roll shaft 5, the first beam body 7, the second beam body 8 and bridge telescopic construction seam 9, wherein: between the first beam body 7 and the second beam body 8, be provided with bridge telescopic construction seam 9, swing tooth plate 1 is fixedly linked by roll shaft 5 and anchorage block 6 and the first beam body 7, and swing tooth plate 1 one end can be rotated around roll shaft 5, swing tooth plate 1 is crossed over bridge telescopic construction seam 9, and the other end is overlapped on the second beam body 8; Fixed tooth plate 2 one end are connected by joggle mode with joggle plate 3, and fixed tooth plate 2 is fixedly linked by the first set bolt 21 and the second beam body 8; Fixed tooth plate 2 and the second beam body 8 junctions are provided with stainless steel backing plate 4; Joggle plate 3 is fixedly connected with the second beam body 8 by the second set bolt 31; Stainless steel backing plate 4 is fixedly connected with the second beam body 8 by carrying bolt 41; Bridge telescopic construction is stitched 9 belows and is provided with rubber seal 10 and drag-line coupling beam device 11.
In the utility model, described swing tooth plate 2 and fixed tooth plate 1 intersect with comb teeth-shaped.
The utility model has the advantage of:
1. swing tooth plate is fixed on the first beam body with roll shaft, can freely rotate.When there is vertical displacement between the first beam body and the second beam body when poor, swing tooth plate can rotate, and keeps bridge deck smooth-going continuously.
2. fixed tooth plate is fixed on the second beam body in joggle mode.When macroseism is attacked, while there is larger lateral displacement between beam body, can slide along horizontal in joggle place, prevention " tooth plate fracture " phenomenon.
3. the cable arrangement between the first beam body and the second beam body, can reduce the probability that severe earthquake action whereabouts beam occurs.
4. sealing rubber pad not only plays waterstop effect, when swing tooth plate and fixed tooth plate near time, also can play the active force mutually clashing between pilot beam body.
5. in macroseism, come interim, the utility model can meet under geological process longitudinally, laterally, vertical and each to rotation, there is better stronger anti-seismic performance.
