Background technology
Along with the development of transportation and the raising of construction standard, bearing is in bridge and Other EngineeringNot only play a supporting role, but also there is the effect of vibration damping, resistance to plucking, release moment of flexure, resist displacement. OrderBefore, often there is in earthquake the situation that precast bridge plate falls from bridge pier beam, bridge plate falls from bridge pier beamFallen reason is, in the time there is earthquake, has produced very large horizontal force and vertical power, makes prefabricated bridgeThe displacement of beam slab occurred level and upper and lower displacement are shelved width when displacement exceedes precast bridge plate on bridge pierAfter, bridge plate will fall, and now, not only bridge is damaged, and pedestrian on bridge, under bridgeAll there will be serious accident with vehicle. Therefore for the problems referred to above, a solution is now proposed.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of bridge girder anti-seismic bearing is provided.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of bridge girder anti-seismic bearing, comprises bridge plate, bridge pier and pedestal, is provided with bridge pier, bridge pier on pedestalOn be provided with bridge plate, its special character is, the upper end of bridge pier is provided with dovetail groove, the bottom of bridge plateBe provided with the projection agreeing with mutually with dovetail groove profile, projection stretches into dovetail groove inside, and projection comprises reinforced concrete shellBody and the buffering energy-consumption body that is arranged on reinforced concrete enclosure interior, be provided with the first shock insulation between projection and dovetail groovePad; The two ends, bottom surface of bridge plate are provided with a pair of to downward-extension and symmetrical fixture block, and fixture block is near a side of bridge pierBe provided with slide block, on bridge pier, the position corresponding with slide block is provided with the chute agreeing with mutually with slide block, and slide block stretches into chuteIn, between slide block and chute, be provided with the second isolation cushion.
Further, buffering energy-consumption body is the flexible filler that is arranged on reinforced concrete enclosure interior, and flexibility used is filled outFilling thing is polyurethane material.
Further, the first isolation cushion is rubber blanket.
Further, the second isolation cushion is laminated steel plate rubber blanket.
Further, the longitudinal section of fixture block is rectangle.
Further, the longitudinal section of chute and slide block is rectangle.
The beneficial effects of the utility model are as follows:
The bridge girder anti-seismic bearing that the utility model provides, simple in structure, by dovetail groove being set and projection is mutualCoordinate, can make bridge plate be fixed on bridge pier, prevent the horizontal displacement of bridge plate; By slide block is setCooperatively interact with chute, can make the further fixing of bridge plate and bridge pier, prevent that bridge plate is because of earthquakeCause and move up and down displacement; And by the setting of the first isolation cushion and the second isolation cushion, more strengthen antidetonationEffect and service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Wherein, 1, bridge plate, 2, bridge pier, 3, pedestal, 4, dovetail groove, 5, projection, 5-1, reinforcing barConcrete housing, 5-2, buffering energy-consumption body, 6, the first isolation cushion, 7, fixture block, 8, slide block, 9, chute, 10,The second isolation cushion.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is elaborated.
As shown in Figure 1, a kind of bridge girder anti-seismic bearing that the utility model embodiment provides, comprise bridge plate 1,Bridge pier 2 and pedestal 3, be provided with bridge pier 2 on pedestal 3, be provided with bridge plate 1 on bridge pier 2, bridge pier 2Upper end is provided with dovetail groove 4, and the bottom of bridge plate 1 is provided with the projection 5 agreeing with mutually with dovetail groove profile, protrudingPiece 5 stretches into dovetail groove 4 inside, and projection 5 comprises reinforced concrete housing 5-1 and is arranged on reinforced concrete housing 5-1Inner buffering energy-consumption body 5-2, buffering energy-consumption body 5-2 is that the flexibility that is arranged on reinforced concrete housing 5-1 inside is filled outFill thing, flexible filler used is polyurethane material. By the setting of this projection, can be to a certain extentThe vibration effect of bringing while eliminating earthquake. Between projection 5 and dovetail groove 4, be provided with the first isolation cushion 6, theOne isolation cushion 6 is rubber blanket; The two ends, bottom surface of bridge plate 1 are provided with a pair of to downward-extension and symmetrical fixture block 7,The longitudinal section of fixture block 7 is rectangle. Such structure setting, can make bridge plate 1 be fixed on bridge pier 2,Prevent the horizontal displacement of bridge plate 1.
