8. boss, 9. flange slide plate, 10. boss slide plate.
Detailed description of the invention
For being more fully understood that the present invention, the invention will be further described with embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of bridge shear key, including upper base plate 1 and lower seat board 2, the marginal position of upper and lower seat board is uniform
Being interval with several screw, upper base plate center is provided with flange 7, and lower seat board center is provided with boss 8, flange and boss phase configuration, convex
Edge internal face is provided with flange slide plate 9, and outer wall of boss face is provided with boss slide plate 10, flange slide plate and boss slide plate and is stainless
Steel plate, the gap between flange slide plate and boss slide plate is 1.5mm～3mm, and when bridge main beam occurs vibration, two slide plates can
There is Relative sliding, play the effect of buffer shock-absorbing, extend bridge service life.
The installation method of a kind of bridge shear key, it is characterised in that comprise the following steps:
(1), preparation is installed, first by the center line of upper base plate and the screw of lower seat board respectively at lower pinner 4 and the bridge of pier stud
Mark on the upper pinner 3 of beam slab, hole devious or the reinforcing bar relative with screw are processed, then by upper and lower seat board spiral shell
Foreign material, loosening concrete in hole are thoroughly removed totally, then are rinsed one time with water, by complete for the reinforcing bar binding of lower pinner, then reinforce benefit
By force, finally also marking out by the sideline of upper and lower seat board, it is simple to check whether that installation puts in place, the center line of screw is when mounted
It is blocked, is only controlled by sideline；
