Detailed description of the invention

As shown in Figure 1, 2, 3, a kind of highway bridge shock-absorbing bearing, including base 1, described base 1 is the top cavity structure with opening, fixedly mounting multi-faceted antivibration pad 3 in base 1 inner bottom surface, the base 1 above multi-faceted antivibration pad 3 is internal is installed with cushion socket 2, and the centre of cushion socket 2 is installed with bridge supports 6, bridge supports 6 outer cover, equipped with balance lasso 4, is provided with horizontal shock-absorbing pad 5 between balance lasso 4 and the upper opening position of base 1。

It is installed with cross-brace device between described balance lasso 4 and bridge supports 6, described bridge supports 6 is cylindrical structural, described balance lasso 4 is cylindrical structural, cross-brace device is at least two-layer, every layer of cross-brace device is all made up of at least three cross-brace sheets 7, the side of cross-brace sheet 7 is fixing with the inwall of balance lasso 4 to be connected, and the opposite side of cross-brace sheet 7 is fixing with the outer wall of bridge supports 6 to be connected。Described base 1 is the top cylindrical empty cavity configuration with opening, described cushion socket 2 is round table-like structure, the diameter of cushion socket 2 is not more than the diameter of base 1 inner chamber, and base 1 upper opening is circular, and the diameter of this circular upper opening is less than the diameter of cushion socket 2。Described horizontal shock-absorbing pad 5 is the circular ring adopting rubber blanket to make, and the outside of horizontal shock-absorbing pad 5 is fixing with base 1 to be connected, and the inner side of horizontal shock-absorbing pad 5 is fixing with the outer wall of balance lasso 4 to be connected。Described multi-faceted antivibration pad 3 be adopt rubber blanket make be shaped as trapezoidal round table-like structure, the bottom diameter of multi-faceted antivibration pad 3 is more than top end diameter, the bottom of multi-faceted antivibration pad 3 is fixedly mounted on the bottom surface of base 1, and the top of multi-faceted antivibration pad 3 is fixing with the bottom surface of cushion socket 2 to be connected。
