Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
With reference to Fig. 1, a kind of highway bridge shock-absorbing bearing, including fixed block 1,1 inside both ends of fixed block symmetrically offer two
A mounting groove 2, the lower inside of mounting groove 2 are horizontally installed with antivibration pad 16, and mounting groove 2 is internally provided with L-type that is horizontal and sliding
Support plate 15, one end of two L-type support plates 15 are connected with support plate 5, L-type support plate jointly through fixed block 1 and end
Second spring 14 is arranged with 15, the both ends of second spring 14 are respectively fixedly connected with 1 upper surface of fixed block and 5 bottom of support plate
Portion, the upper horizontal of support plate 5 are equipped with base 6, beam 13 are connected between base 6 and support plate 5, the top of base 6 is consolidated
Surely bridge supports 11 are connected with, damping device is connected with bridge supports 11；When 11 longitudinal stress of bridge supports, antivibration pad 16
Can tentatively it be buffered, support plate 5 pushes, and the extruding of 14 stress of second spring carries out secondary buffer, is pushed in support plate 5 same
When drive 15 slide downward of L-type support plate, L-type support plate 15 extrudes beam 13, and beam 13 can carry out again
