Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a bridge expansion joint backplate installation mechanism, cement layer 2 including embedded groove 1 and bridge, the equal fixedly connected with fixed plate 11 in bottom in embedded groove 1 both sides, fixed plate 11 is located the inside on cement layer 2, setting through fixed plate 11, with fixed plate 11 pre-buried to the inside on cement layer 2 in advance, make the position of embedded groove 1 more stable, a plurality of fixed blocks 12 of bottom fixedly connected with of embedded groove 1 inner chamber, fixed block 12 is located both ends around spacing draw-in groove 5, setting through fixed block 12, spacing effect has been played to spacing card strip 4, backplate 3 and the stability of spacing card strip 4 have been improved.

The top of embedded groove 1 is provided with backplate 3, and two lugs 13 of the positive fixed surface of backplate 3 are connected with, and the arc recess 14 with lug 13 looks adaptation is seted up on the back surface of backplate 3, and lug 13 on one backplate 3 can insert in the arc recess 14 on the adjacent backplate 3, realizes connecting between the two adjacent backplates 3, has improved the wholeness and the stability of this installation mechanism. The guard plate 3 is provided with a counter bore 15 matched with the bolt 7, and the bolt 7 is not higher than the top of the guard plate 3 due to the arrangement of the counter bore 15, so that the damage of the counter bore 15 to vehicles and pedestrians is avoided.
