Abstract
The utility model belongs to the technical field of a bridge supporting base, and discloses a shock-absorption supporting base preventing girder falling. The supporting base mainly comprises an upper supporting base plate, a middle steel liner plate, a bearing rubber plate, a lower supporting base plate and shear bolts. The upper supporting base plate is provided with a limit barrier strip, the inner side of the limit barrier strip is provided with a shock-absorbing strip, the lower supporting base plate is provided with a check ring, and a damping ring is disposed on the inner side of the check ring. When an earthquake occurs, the limit barrier strip on the upper supporting base plate acts on the middle steel liner plate, and partial earthquake energy can be absorbed through the shock-absorbing strip. When earthquake force reaches the defense limit, the shear bolts of a pier are sheared. The damping ring on the inner side of the check ring on the lower supporting base plate repeatedly collides with a pad stone in an elastic mode, and the damping ring is repeatedly squeezed to absorb the earthquake energy. Meanwhile, the check ring provided with the damping ring inside directly acts on the side face of the pad stone, and a girder body is effectively prevented from falling due to combined action of earthquake energy reduction and blocking of the whole pad stone.
Description
Technical field
The utility model belongs to the bridge pad technical field, relates in particular to a kind of girder falling shock mount.
Background technology
How bridge structure produces larger relative displacements between the structure of upper and lower part under severe earthquake action, when displacement surpasses the actual restrainer length of bridge or the limit, beam will fall, cause the interruption of traffic, bring very big difficulty to disaster relief work, cause huge loss.Therefore how reducing seismic energy in the earthquake, reduce earthquake displacement, prevent the bridge beam that falls by structure design, is the major tasks of bridge and attachment design thereof.And Bridges in Our Country mainly takes to arrange anti-fall girder apparatus at present between beam and pier, prevents that beam section from occuring laterally or longitudinally displacement under the loads such as seismic forces.Existing anti-fall girder apparatus mostly is independent design, installation, and the cost that the bridge consumptive material is many, transportation is installed is high.
The utility model content
The technical problems to be solved in the utility model just provides a kind of bearing, damping and anti-fall girder apparatus of integrating, realize that consumptive material is few, easy transportation and installation, cost are low, when having the earthquake generation, can relax the earthquake energy impact, prevent falling of Bridges During Earthquake superstructure, avoid earthquake bridge construction to be brought the girder falling shock mount of infringement.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise upper bracket plate, middle steel liner plate, pressure-bearing rubber tile, lower support plate and shear studs, described upper bracket plate is provided with spacing blend stop, spacing blend stop installed inside has shock absorption strip, described lower support plate is provided with back-up ring, and the back-up ring inboard is provided with damped ring.
Its additional technical feature is: the described spacing blend stop that shock absorption strip is installed is symmetrically arranging in the bearing glide direction; Described back-up ring and damped ring are arranged on the lower support plate below and arrange around pinner, leave the gap between damped ring and the pinner; Be provided with energy dissipating plate, lower energy dissipating plate below the described upper bracket plate; Described shock absorption strip, damped ring are elastic body.
Girder falling shock mount provided by the utility model compared with prior art, the upper bracket plate is provided with the spacing blend stop with shock absorption strip, lower support plate is provided with the back-up ring with damped ring.When earthquake was arrived, steel liner plate in the middle of the limiting block bar on the upper bracket plate acts on relied on shock absorption strip absorption portion seismic energy, and when seismic forces reaches when setting up defences the limit, the pier shear studs is cut off.The damped ring of back-up ring inboard Elastic Impact pinner repeatedly on the lower support plate, damped ring is extruded the absorption seismic energy repeatedly.Simultaneously, in establish damped ring back-up ring act directly on the pinner side, the acting in conjunction that the minimizing of seismic energy and whole pinner stop has prevented that effectively the beam body from falling.The back-up ring of lower support plate and bottom can adopt casting technique, and once-forming also can adopt parts processing, and is easy to process, has improved working (machining) efficiency, consumptive material is few, has reduced cost of production and easy for installation when playing cushioning effect.
As required, the spacing blend stop that shock absorption strip is installed is symmetrically arranging in the bearing glide direction.Arrange all around and back-up ring and damped ring are arranged on the lower support plate below and center on pinner, leave the gap between damped ring and the pinner, be conducive to damping.Be provided with energy dissipating plate, lower energy dissipating plate below the upper bracket plate, cut off in the pier shear studs, the damped ring of back-up ring inboard is repeatedly during the Elastic Impact pinner on the lower support plate, the friction pair effect that upper energy dissipating plate, lower energy dissipating plate consist of, further earthquake energy.Shock absorption strip, damped ring are elastic body, good damping effect.
