Abstract
The utility model belongs to the field of bridge bearing technology and discloses a friction pendulum shock-reduction seismic-isolation spherical supporting seat which is characterized by comprising an upper base plate, a middle spherical crown plate and a lower base plate. A plane friction pair is disposed between the upper base plate and the middle spherical crown plate. An upper spherical surface friction pair is disposed between the middle spherical crown plate and the lower base plate. A side friction pair is disposed between the upper base plate and the lower base plate. A base is disposed under the lower base plate. The bottom surface of the lower base plate is a convex spherical surface or a convex cylindrical surface. The top surface of the base is a concave spherical surface or a concave cylindrical surface matched with the convex spherical surface or the convex cylindrical surface. A limiting steel ring or a limiting steel plate matched with the lower base plate is fixed with the base through shear bolts. A lower spherical surface friction pair or a cylindrical surface friction pair is disposed between the lower base plate and the base. When an earthquake comes, the shear bolts can be sheared off, limiting devices are opened, the lower base plate slides in the base, a bridge body is isolated from abutments, and consequently the bridge body is protected and can be automatically reset after the earthquake.
Description
Technical field
The utility model belongs to the bridge pad technical field, relates in particular to a kind of friction pendulum and subtracts the shock insulation spherical bearing.
Background technology
The bearing that in bridge engineering construction, uses comprises board-like bearing, spherical bearing, pot bearing etc.; The structure of spherical bearing comprises upper base plate, middle spherical crown plate and following seat board; Be provided with the planar friction pair between upper base plate and middle spherical crown plate; Be provided with the sphere friction pair between middle spherical crown plate and following seat board, be provided with the side friction pair between upper base plate and following seat board.During installation, spherical bearing directly is fixed on and supports at the bottom of pinner and the beam.When normal the use; Common spherical bearing can satisfy the service requirement of bridge, but under emergency case such as strong wind, earthquake, common spherical bearing just can't satisfy the requirement of protection bridge; Can seismic energy be delivered to the beam body from pier, cause impaired, the structural deterioration of bridge.
The utility model content
The technical problem that the utility model will solve just provides a kind of can beam body and pier being kept apart, and makes most of seismic energy subtract the shock insulation spherical bearing from the friction pendulum that pier is delivered to the beam body.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: comprise upper base plate, middle spherical crown plate and following seat board; Be provided with the planar friction pair between upper base plate and middle spherical crown plate; Be provided with the sphere friction pair between middle spherical crown plate and following seat board, be provided with the side friction pair between upper base plate and following seat board, be provided with base below the said time seat board; The bottom surface of following seat board is protruding sphere or projection face; The end face of base is concave spherical surface or the recessed cylinder that is complementary with protruding sphere or projection face, and the spacing steel loop or the spacing steel plate that are complementary with following seat board fix through shear studs and base, are provided with lower peripheral surface friction pair or cylinder friction pair between following seat board and the base.
The friction pendulum that the utility model provided subtracts the shock insulation spherical bearing, and when bridge normally moved, fixing spacing steel loop or the spacing steel plate of shear studs made down seat board spacing, and friction pendulum subtracts the shock insulation spherical bearing and common spherical bearing function is just the same.Earthquake comes interim, and when horizontal force that bridge bore during greater than the shear studs shear strength, shear studs is cut off; Stopping means such as spacing steel loop or spacing steel plate are opened; Following seat board slides in base, and beam body and pier are kept apart, and makes most of seismic energy be delivered to the beam body from pier.It is to utilize the vibration period of the design extending structure on the arc surface or the face of cylinder that friction pendulum subtracts at a distance from spherical bearing isolation energy dissipation principle; To reduce the enlarge-effect that structure causes because of geological process significantly; And following seat board and base reach earthquake energy through the friction between the arc surface or the face of cylinder; Reduce the input of seismic energy, thus protection beam body.After the earthquake, the arc surface or the face of cylinder of following seat board and base have auto-reset function.
