Specific embodiment
As depicted in figs. 1 and 2, according to one preferred embodiment of fishback lateral deflection device of the utility model, including comb
Tooth plate 1, fishback bottom plate 2 carry out part cutting on fishback 1 and obtain cutting seam I 3, carry out part cutting on fishback bottom plate 2
Cutting seam II 4 is obtained, fixed plate 5 is installed below fishback bottom plate 2, is welded with slide plate between fishback 1 and fishback bottom plate 2
I 6, slide plate I 6 uses tetrafluoro plate material, can reduce the frictional force between contact surface, to guarantee the lateral displacement of fishback,
Be welded with slide plate II 7 between fixed plate 5 and fishback bottom plate 2, slide plate II 7 uses tetrafluoro plate material, can reduce contact surface it
Between frictional force, to guarantee the lateral displacement of fishback.Cutting seam I 3, cutting are stitched II 4, fixed plate 5 and are slided in the present embodiment
Plate I 6, II 7 collective effect of slide plate can create conditions for 1 lateral displacement of fishback, make when bridge is by Lateral Force
Fishback 1 is able to carry out lateral displacement, increases the ability of the adaptation actual place of fishback 1, substantially reduces fishback 1
Damage probability.The service life for increasing expansion joint, it is hidden to greatly reduce the traffic that tooth plate tilting is caused caused by loosening because of tooth plate
Suffer from.
Fishback 1, slide plate I 6, fishback bottom plate 2, slide plate II 7, fixed plate 5 and anchor ring 9 connect by the way that bolt is successively fixed
It connects.5 bottom surface of fixed plate is bolted to connection with anchor ring 9, and anchor ring 9 is closed type ring structure, the top margin of anchor ring 9 and bottom
