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.Antivibration block device 5 described in the utility model is arranged on the both sides of bent cap 1, including is arranged on the side of bent cap 1
The block 6 of edge, the inner side of block 6 is connected with fixation steel plate 7, and the inner side of fixation steel plate 7 is provided with the first vertical chute 13；X-type branch
One end of frame 8 is connected to fixation steel plate 7, and the other end is connected to fixing steel plate 9；The outside of fixing steel plate 9 is provided with vertical second
Chute 14, inner side is provided with neck, and block rubber 10 is connected with by neck；The X-type support 8 includes two support columns, two branch
The center of dagger is mutually hinged and forms 4 legs, is connected with spring 12 between two adjacent legs；Underlying two
Individual leg is fixedly connected with fixation steel plate 7 and fixing steel plate 9 respectively, and two legs above can be in the first chute 13 and
In two chutes 14 slidably；Or two legs above are fixedly connected with fixation steel plate 7 and fixing steel plate 9 respectively,
Two legs positioned at upper and lower can be in the first chute 13 and the second chute 14 slidably.The fixation steel plate 7, which is fixed, to be connected
Dowel 11 is connected to, dowel 11 is embedded in inside block 6.Concrete block 6 before pouring, the dowel 11 of fixation steel plate 7 should first with
The bar connecting of configuration together, can take the forms such as welding to be fixed in block 6.
Specifically, the need for according to the actual antidetonation of bridge structure or seismic isolation design, carrying the first chute by one piece in advance
13 fixation steel plate 7 is welded to connect among block 6 by dowel 11, then in the inner side of fixing steel plate 9 parcel covering block rubber
10.Two legs of the below or above of X-type support 8 are welded to connect with fixation steel plate 7 and fixing steel plate 9 respectively again, top
Or two legs of lower section are then placed in the first chute 13 and the second chute 14.Last adjacent two leg in X-type support 8
