Further, the cursor is shuttle shape plank frame, and width is gradually reduced from middle part to both ends, is arranged at center
There is the through-hole for being set in shaft.
Further, the auxiliary support is circular cone structure, and the groove that push-pull rod can be made to protrude into is offered at top,
The second shaft is interspersed between two side elevation of groove, the push-pull rod end is rotatably set in second shaft.
Further, the push-pull rod uses steel pipe, in steel duct fill concrete, the outside fitting compound increasing of carbon fiber
Strong plastic sheet.
The utility model has the beneficial effects that keeping cursor auxiliary anti-by the installing connecting rods mechanism on conventional base support
Support is shaken by itself bending deformation come the seismic energy that dissipates, and more advanced earthquake can be resisted, simultaneously because link mechanism can
It effectively prevent falling beam, after macroseism, the deformed damaged of cursor makes more convenient replacing and safeguard, cost is relatively low, structure
Simply, easy to spread.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the utility model auxiliary support structural schematic diagram；
Fig. 3 is enlarged drawing at the utility model A.
Specific embodiment
The utility model is described in detail below with reference to attached drawing:
It is as shown in Figs. 1-3:
For bridge caused by the main damage form under geological process is along the cross force in bridge width direction, this is practical new
Type provides a kind of shock-absorbing bridge support structure, including the shock mount 3 being mounted between bridge 1 and bridge pier 2, the damping branch
Seat is sliding laminated rubber bearing, is vertically superimposed by rubber slab 31 and steel plate 32, outside is enclosed with rubber protective layer
33, width direction of the main glide direction of the shock mount 3 along bridge 1；It is equipped on the side elevation of the shock mount 3
Backing plate 4, the backing plate 4 are fixedly connected on the steel plate 32 in shock mount 3, make backing plate 4 in earthquake together with shock mount 3
It moves left and right, the shaft 41 parallel with 1 extending direction of bridge is provided on the backing plate 4, can turn in the shaft 41
Dynamic to be arranged with cursor 5,5 both ends of cursor are respectively hinged with a push-pull rod 6, and the end of the push-pull rod 6 is hinged on auxiliary
It helps on support 7, the auxiliary support 7 is fixedly connected on bridge pier 2 by foundation bolt；The line of two auxiliary supports 7
Along the width direction of bridge 1, entire link mechanism is made mainly to assist the transverse translation of bridge 1 in this way.
The shock mount 3 is cube structure, is provided with connecting plate 34 on upper and lower end face, sets on the connecting plate 34
It is equipped with anchor bolt hole, upper junction plate is connect by anchor bolt with bridge 1, and lower connecting plate is connected by anchor bolt and bridge pier 2
It connects.
The backing plate 4 is connect by bolt with steel plate 32, and the backing plate 4 is rectangular configuration, is arranged along 4 short transverse of backing plate
There are two rows of bolts hole, one row of top is circular hole 42, and one row of lower section is strip-shaped hole 43；The bolt passing through bolt hole and setting are in steel
Threaded hole on 32 side elevation of plate is threadedly coupled.Due to shock mount 3 in geological process happens is that shear-deformable, top is opposite
Exist in lower part and be displaced, therefore by the way that row's circular hole 42 is arranged above backing plate 4 for fixing, row's strip-shaped hole 43 is arranged in lower section
For allowing backing plate 4 that small sliding occurs relative to the steel plate 32 below shock mount 3 when shock mount 3 deforms, with
The service life of backing plate 4 is improved, while big influence will not be generated to the deformability of shock mount 3.
The cursor 5 is shuttle shape plank frame, and width is gradually reduced from middle part to both ends, is provided at center for covering
The through-hole being located in shaft 41.By the improvement of above structure, 5 both ends of cursor are respectively connected with a push-pull rod 6, send out in earthquake
When raw, since auxiliary support 7 is fixed on bridge pier 2, when bridge 1 shakes, shock mount 3 deforms, so that backing plate 4
Cursor 5 is driven to be subjected to displacement relative to the auxiliary support 7 of two sides, that is, cursor 5 is between the auxiliary support 7 of two sides
It shakes, in double swerve, the push-pull rod 6 of two sides is applied to the power at 5 both ends of cursor always towards same direction, therefore is to turn
Swing arm occurs bending and deformation, and bending deformation can also occur while shuttle shape plank frame makes cursor 5 be able to bear larger moment of flexure,
It is pushed and pulled repeatedly by the push-pull rod 6 at both ends, with bending deformation dissipation seismic energy.
The auxiliary support 7 is circular cone structure, the groove 71 that push-pull rod 6 can be made to protrude into is offered at top, described
The second shaft 72 is interspersed between 71 liang of side elevations of groove, 6 end of push-pull rod is rotatably set in second shaft 72
On.
The push-pull rod 6 uses steel pipe, in steel duct fill concrete 61, outside fitting carbon fiber composite reinforced plastics
Sheet material 62.By the improvement of above structure, the compression strength of concrete 61 is higher, and carbon fiber composite reinforced plastics sheet material 62
Tensile strength is higher, then cooperates steel pipe, is conducive to the rigidity for improving steel pipe 6, deformation is made to occur mainly in cursor 5, and unlikely
It is destroyed in making push-pull rod that stability occur, is further reduced the cost in the replacement maintenance of earthquake, damping effect is improved in earthquake
Fruit, while being also the guarantee of restrainer.
The utility model has the beneficial effects that keeping cursor auxiliary anti-by the installing connecting rods mechanism on conventional base support
Support is shaken by itself bending deformation come the seismic energy that dissipates, and more advanced earthquake can be resisted, simultaneously because link mechanism can
It effectively prevent falling beam, after macroseism, the deformed damaged of cursor makes more convenient replacing and safeguard, cost is relatively low, structure
Simply, easy to spread.
Above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although referring to preferred embodiment pair
The utility model is described in detail, those skilled in the art should understand that, it can be to the technology of the utility model
Scheme is modified or replaced equivalently, and without departing from the objective and range of technical solutions of the utility model, should all be covered
In the scope of the claims of the utility model.
