Description
Technical field
The utility model is related to bridge earthquake resistance and bridge subtracts technical field of isolation, and in particular to have multistage antidetonation to one kind
The spring-rubber damping device of function.
Background technology
The earthquake disaster occurred in recent decades in world wide generates significant impact to Bridge Earthquake Resistance Design theory.Its
In, the bridge collision under geological process is considered as to influence a key factor of bridge structure anti-seismic performance, thus by more
Carry out more attention.Many bridge structures cause bridge that upper beam occurs after shake due to being not provided with reasonably subtracting isolation measure
Body falls the situation that beam or bottom pier stud are damaged, so that paralysis situation occurs in bed rearrangement bridge, seriously hinders the smooth of traffic, very
To having threatened safety of life and property.Therefore how the displacement of beam body to be limited in necessarily using bridge structure seismic isolation device
In the range of so strengthen antivibration capability of bridge turn into science of bridge building seismic resistance field research emphasis.
Short/Medium Span Bridge generally sets using laminated rubber bearing and laterally Antivibration block at it, and it is restrainer shake
Evil or a kind of conventional measure for ensureing bearing seismic seeurity.But under strong earthquake motion effect, beam body lateral displacement is larger,
Easily collided with Antivibration block, in turn result in block and be sheared destruction or even fall beam, its main cause is made in earthquake
Effective buffering is not obtained to the percussion of block with lower beam body, seismic energy is not dissipated in time yet.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of spring-rubber damping with multistage function of seismic resistance and filled
Put, solve existing highway bridge beam body lateral displacement under geological process and greatly, easily cause block and be sheared destruction or even fall beam
Defect, the seismic energy that dissipation bridge is subject to improves the anti-seismic performance of bridge.
In order to solve the above technical problems, the technical scheme that is used of the utility model for：
A kind of have the spring-rubber damping device of multistage function of seismic resistance, including is vertically arranged in the block at bent cap edge,
Steel plate is connected with the inside of block；One end of spring is connected to steel plate, and the other end is connected to locating slot, the inner side connection of locating slot
There is block rubber.
According to such scheme, the bottom of the block rubber is connected with friction pad.
According to such scheme, the block rubber is close to beam body side provided with the web angle of inclination identical slope with beam body
Face.
According to such scheme, the Interal fixation is connected with dowel, and dowel is embedded in inside block.
Compared with prior art, the beneficial effects of the utility model are：Under small shake effect, become by the extruding of block rubber
The sliding friction of shape and friction pad plays isolating affection come the displacement for limiting beam body generation and the seismic energy that dissipates.Shaking greatly
Under effect, block rubber and friction pad drive spring to move consumed energy together, play cushioning effect, it is to avoid block directly by
Girder, which hits, to be destroyed, and is effectively improved the anti-seismic performance of bridge structure.Block rubber after spring breaking down with also allowing for simultaneously
Maintenance is changed.The coefficient of friction for the friction pad that damping and isolation effect of the present utility model can be bonded by changing under block rubber and
The parameters such as spring rate are adjusted, to meet the antidetonation demand of different bridge structures.
Brief description of the drawings
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings, wherein：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the cross-sectional view of A-A in Fig. 1；
Fig. 3 is riding position schematic diagram of the utility model on bridge.
Each label is interpreted as in figure：1- bent caps, 2- bearing cushion blocks, 3- rubber supports, 4- beam bodies, 5- damping devices, 6-
Block, 7- steel plates, 8- springs, 9- locating slots, 10- block rubbers, 11- friction pads, 12- dowels, 13- webs.
Embodiment
The bent cap 1 of general bridge is provided with bearing cushion block 2, and bearing cushion block 2 is provided with rubber support 3, and beam body 4 is then placed in
On rubber support 3.Damping device 5 described in the utility model is arranged on the both sides of bent cap 1, specifically includes and is vertically arranged in bent cap
The block 6 at 1 edge, the inner side of block 6 is connected with steel plate 7, and the dowel 12 of steel plate 7 is embedded in the inside of block 6；The one of spring 8
End is connected to steel plate 7, and the other end is connected to U-shaped pre-manufactured steel locating slot 9, and the inner side of locating slot 9 is connected with block rubber 10, block rubber
10 bottom is bonded with friction pad 11.Block rubber 10 is close to the side of beam body 4 provided with identical with the angle of inclination of web 13 of beam body 4
It is domatic.
Specifically, according to the actual design needs for subtracting shock insulation of bridge structure, one piece of certain size is carried four in advance
The steel plate 7 of dowel 12 is embedded in the inner side of block 6, will be configured before the concrete of block 6 is poured in dowel 12 and concrete block 6
Bar connecting, can take welding etc. form fix, then block rubber 10 is processed into and beam body 4 close to the side of beam body 4
The gradient identical of web 13 is domatic, and friction pad 11 is bonded in into the bottom of block rubber 10, finally by the two ends of spring 8 point
It is not welded on the medial surface of steel plate 7 and U-shaped pre-manufactured steel locating slot 9, so just forms the spring with multistage function of seismic resistance
Rubber shock-absorbing device 5.
The spring 8 of the present embodiment can be replaced elastic-plastic damper, U-shaped pre-manufactured steel locating slot 9 can be replaced box or
The locating slot of other forms, the vertical bridge of bridge can use this damping device 5 to block, abutment position.
Applicable cases of the present utility model are as follows：Under small shake effect, the direction across bridge of beam body 4 produces less sidesway, beam body 4
Contacted with the slope of the block rubber 10 of the damping device 5, effect of impact will force block rubber 10 to deform, bridge structure can pass through
The effect of buffering and shock insulation is played in the crimp of block rubber 10 and the sliding friction of friction pad 11 below.Shaking greatly
Under effect, the direction across bridge of beam body 4 produces larger displacement, now block rubber 10 and friction pad 11 will outside lateral movement together, by
In the presence of spring 8, this process can be consumed substantial amounts of seismic energy by the compression of spring 8, efficiently avoid beam
Body 4 directly bumps against with block 6, so as to significantly reduce the direct collision destruction of horizontal block 6 and laterally fall the generation of beam.Should
Damping device 5 takes full advantage of the crimp of block rubber 10 and the deformation of spring 8 come the seismic energy that dissipates, and serves well
Subtract function of shock insulation, significantly improve the security of bridge structure.
