Specific embodiment
As depicted in figs. 1 and 2, one preferred embodiment of fishback lateral deflection device according to the invention, including fishback
1, fishback bottom plate 2 carries out part cutting on fishback 1 and obtains cutting seam I 3, part cutting is carried out on fishback bottom plate 2 and is obtained
Cutting stitches II 4, is equipped with fixed plate 5 below fishback bottom plate 2, slide plate I 6 is welded between fishback 1 and fishback bottom plate 2,
Slide plate I 6 uses tetrafluoro plate material, can reduce the frictional force between contact surface, to guarantee the lateral displacement of fishback, Gu
Slide plate II 7 is welded between fixed board 5 and fishback bottom plate 2, slide plate II 7 uses tetrafluoro plate material, can reduce between contact surface
Frictional force, to guarantee the lateral displacement of fishback.Cutting seam I 3, cutting seam II 4, fixed plate 5 and slide plate in the present embodiment
I 6, II 7 collective effect of slide plate can create conditions for 1 lateral displacement of fishback, to comb when bridge is by Lateral Force
Tooth plate 1 is able to carry out lateral displacement, increases the ability of the adaptation actual place of fishback 1, substantially reduces the damage of fishback 1
Bad probability.The service life for increasing expansion joint greatly reduces tooth plate caused by loosening because of tooth plate and tilts caused hidden trouble of traffic.
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
