The technical scheme includes that a spherical force transmission head (3) fixedly connected with a shock-absorbing tenon is arranged at the top end of the shock-absorbing tenon, and the spherical force transmission head (3) positioned inside a connecting sleeve (2) is combined with the sleeve in a matching manner; the connecting sleeve (2) is fixedly connected to the bottom of a beam body (1) to form a structure enabling the spherical force transmission head to rotate in an optional direction relatively to a sleeve body and the beam body (1); and a circular revolving body with variable sections is arranged on a working section (4) of the upper portion of the shock-absorbing tenon, an anchoring section (7) on the lower portion of the shock-absorbing tenon is fixedly connected inside a concrete abutment (6), a circular groove surrounding the shock-absorbing tenon is arranged on the upper end face of the concrete abutment (6), and a transitional sealing ring (5) is arranged inside the circular groove. The structure used for bearing horizontal loading and horizontal shifting of the beam body is capable of meeting use requirements on transverse rigidity of a bridge by a train in normal running, and has sufficient ductility in an earthquake so as to lower damage of the earthquake on the abutment.
Description
Technical field
The utility model belongs to the seismic isolation technology that subtracts of bridge and building structure, mainly proposes a kind of Simple Supported Railway Bridges beam type damping tenon structure.
Prior art
Along with the continuous intensification of the mankind to the understanding of earthquake, all kinds of buildings comprise that bridge all has higher requirement to structural seismic.It is in the junction of beam body and pier vibration absorption and isolation support to be installed that bridge subtracts seismic isolation technology, as laminated rubber bearing, pot rubber bearing, lead core rubber support etc., by changing the earthquake response that free vibration period of structure and damping reduce structure.Subtracting the traditional seismic design of isolation design replacement in the high intensity Zone employing is a kind of desirable selection.But since the neoprene bearing lateral stiffness a little less than, be difficult to satisfy the requirement of railroad bridge power performance aspect.The viscoid shock mount belongs to the viscous damping energy-dissipating device, and its shock insulation principle is the purpose that reaches absorption and dissipates vibration energy by the sticky shearing of viscoid.This class bearing generally is that interior case of bearing and bridge superstructure are fixed, and bearing outer container and bridge substructure are fixed, and change the size of the surface of shear of viscoid, can reach the purpose of regulating the bearing performance.Its damping effect is more satisfactory, but its structure and processed complex.Hyperboloid spheroidal bearer of shock absorption and insulation is the improvement to common spherical bearing, because this bearing adopts the hyperboloid structure, after the bearing horizontal restraint is disengaged during earthquake, in the occurred level displacement, because friction produces power consumption, the hyperboloid structure can change the structural vibrations cycle, the basic frequency when avoiding earthquake simultaneously.But this bearing installation dimension is bigger, uses on a large scale to be subjected to certain limitation in simply supported girder bridge.
Summary of the invention
The utility model proposes a kind of Simple Supported Railway Bridges with beam type damping tenon structure, in order to horizontal load and the horizontal movement of bearing the beam body, even the suffered horizontal seismic force of beam body reaches bridge pier by it.Its objective is to make it can satisfy under the normal operation train under earthquake, have enough ductility to reduce the harm of earthquake again to pier to reach to the instructions for use of lateral rigidity of bridge.
The utility model is to finish the technical scheme that its invention task taked to be: a kind of Simple Supported Railway Bridges is with beam type damping tenon structure, described its main body of damping tenon structure is the damping tenon, the top of described damping tenon has the ball-shaped driving head and is fixedly connected with damping tenon top, the ball-shaped driving head is in order to realize the hinged power transmission of damping tenon, the ball-shaped driving head on damping tenon top is positioned at branch sleeve and joins with sleeve kiss and combines, and makes ball-shaped driving head and branch sleeve hinged; Described branch sleeve connects firmly in beam body bottom, but constitutes the structure that the ball-shaped driving head rotates relative to cylindrical shell, beam body any direction; Its top active section of described damping tenon is a circular variable cross-section revolving body, damping tenon bottom anchoring section connects firmly in concrete pier base in pre-buried mode, have circular trough in the upper surface of concrete pier base and make circular grooved ring enclose the damping tenon, in circular trough, have the transition joint ring.
A kind of Simple Supported Railway Bridges that the utility model proposes beam type damping tenon structure has following characteristics:
(1) normal function of use: under the regular service conditions, guarantee the transmission of bridge horizontal load and the absorption of horizontal movement.
(2) cycle stretch-out function: under seismic condition, can avoid the frequency range that seismic energy is concentrated by extending structure natural vibration period, thereby reduce the seismic response of structure.
(3) energy dissipation function: under seismic condition, by the material in-fighting seimic structural response of decaying.
