Abstract
The utility model relates to a kind of shock-absorbing bridge support, its composition comprises: top board and base plate, described top board is connected with block rubber, described block rubber is connected with steel cylinder seat, described steel cylinder seat is connected with described base plate, described top board and described base plate two ends are welded with fixing cushion block, and described fixing cushion block is welded with alloy rope, and described alloy rope is arranged to X-type through described steel cylinder seat.The relative displacement of beam body and bridge pier when the utility model can provide geological process by arranging block rubber, thus make alloy rope can play super-elasticity power consumption effect, with the over-large displacement of limit superstructure along bridge to, direction across bridge; Alloy rope is set initial tensile force is provided, enhancing the vertical anti-pulling ability of bearing, by controlling the temperature of alloy rope after vibrations terminate, Seismic Isolation of Isolation Layer and structure being automatically reset, make the displacement energy of Seismic Isolation of Isolation Layer access effective control, there is good damping, isolating affection.
Description
technical field:
the utility model relates to a kind of shock-absorbing bridge support.
background technology:
most widely used in structures isolation effect is at present laminated rubber bases and lead core rubber support.Laminated rubber bases is because damping is less and distortion these unfavorable factors comparatively large make it must use together with other dampers just to have good damping effect; Although lead core rubber support has good damping effect, but the increase of lead for retractable pencil makes the automatic recovery ability of vibration-isolating system greatly reduce, the common drawback of these two kinds of bearings is that shock insulation frequency band is narrower, can not realize having effective damping, isolating affection to the seismic wave of multifrequency feature.
summary of the invention:
the purpose of this utility model is to provide a kind of shock-absorbing bridge support.
above-mentioned object is realized by following technical scheme:
a kind of shock-absorbing bridge support, its composition comprises: top board and base plate, described top board is connected with block rubber, described block rubber is connected with steel cylinder seat, described steel cylinder seat is connected with described base plate, described top board and described base plate two ends are welded with fixing cushion block, and described fixing cushion block is welded with alloy rope, and described alloy rope is arranged to X-type through described steel cylinder seat.
described shock-absorbing bridge support, is provided with lead dot in described block rubber, and described lead dot is one or more.
described shock-absorbing bridge support, described block rubber is formed by laminar rubber and steel plate adhering and pressing.
the beneficial effects of the utility model:
the relative displacement of beam body and bridge pier when the utility model can provide geological process by arranging block rubber, thus make alloy rope can play super-elasticity power consumption effect, with the over-large displacement of limit superstructure along bridge to, direction across bridge; Alloy rope is set initial tensile force is provided, enhancing the vertical anti-pulling ability of bearing, by controlling the temperature of alloy rope after vibrations terminate, Seismic Isolation of Isolation Layer and structure being automatically reset, make the displacement energy of Seismic Isolation of Isolation Layer access effective control, there is good damping, isolating affection.
the utility model is by the rational structure of General Purpose Rubber bearing and alloy rope, and bearing is had, and isolation property is good, energy-dissipating property is good and can the strong multiple dimension shock-proof performance of recovery capability.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
detailed description of the invention:
embodiment 1:
a kind of shock-absorbing bridge support, its composition comprises: top board 1 and base plate 2, described top board is connected with block rubber 3, described block rubber is connected with steel cylinder seat 4, described steel cylinder seat is connected with described base plate 2, described top board and described base plate two ends are welded with fixing cushion block 5, and described fixing cushion block is welded with alloy rope 6, and described alloy rope is arranged to X-type through described steel cylinder seat.
embodiment 2:
shock-absorbing bridge support according to embodiment 1, is provided with lead dot 7 in described block rubber, described lead dot is one or more.
embodiment 3:
shock-absorbing bridge support according to embodiment 1 or 2, described block rubber is formed by laminar rubber and steel plate adhering and pressing.
