Beneficial effects of the present invention：
1. this utility model is additionally arranged anti-fall girder apparatus between the top steel plate and bottom steel plate of bearing, reasonably limits and props up
Seat moves, and prevents bridge superstructure from departing from bearing, largely prevent beam body and falls the harm of sill bolt, protects
Bridge security.
2. bearing stress of the present utility model is greatly improved, and seat structure size is reduced, and facilitates active service disease
The replacing of evil sheet-type support, greatlys save space and cost.
3. intermediate rubber of the present utility model adopts casting type polyurethane, is integrally improved the performance of bearing from the inside to the outside,
Extend bearing service life；Its design stress can be promoted to 15 MPa, can be substantially reduced supporting stand size, strengthens bearing rotation
Energy.
