Description
Technical field
The utility model relates to a kind of improvement of damping pot rubber bearing, particularly satisfies the pot rubber bearing of bridge vibration damping dissipating functions.
Technical background
Pot rubber bearing can be divided into fixed bearing, multidirectional freely movable bearing, unidirectional freely movable bearing, antidetonation type bearing according to the performance difference.Antidetonation type pot rubber bearing comprises the undersetting body that is fixed on the bridge pier in the structure, be fixed on the upper bracket body on the body of a bridge.Be sequentially set with pressure-bearing rubber tile, seal washer and middle steel liner plate at the bottom of the rectangle basin of undersetting body.The level that forms between the upper and lower bearing body by the stainless steel liner plate in being arranged at the bottom of the upper bracket body rectangle basin and polyfluortetraethylene plate is slidingly matched relatively, is provided with Vibration damping block between upper bracket body basin type limit and middle steel liner plate upper end.Currently used is to have certain rigidity in rubber or the polyurethane to have the materials processing manufacturing of certain elastic performance to form again.It has damping capacity can bear certain horizontal force again, and can produce certain displacement again when the horizontal force that is subjected to reaches certain limit, to slacken damage of external force.Above structure often satisfies the demand that the earthquake horizontal force strengthens by the physical dimension that increases structural member.And do not have the effect of energy-absorbing, vibration damping in actual use.When earthquake took place, by bearing and bridge pier antagonism, the stress to bridge did not have clear improvement the seismic forces that is produced like this, makes the failure energy that is delivered to bridge and bridge pier can not get effectively reducing fully.
Summary of the invention
The purpose of this utility model is, improve the structural shortcoming of original antidetonation type pot rubber bearing, particularly to the further improvement of vibration damping structure, make it not only have the pooling feature of general pot rubber bearing to precipitate horizontal destructive power, and can absorb the internal energy that is converted into the antidetonation assembly, and above-mentioned energy efficient is distributed on a plurality of block of wood, make girder construction evenly stressed, more effectively subdue the infringement that earthquake or the unexpected impact property volume production that produces are given birth to.
Comprise the undersetting body that is fixed on the bridge pier in the structure of the utility model after and be fixed on upper bracket body on the body of a bridge the concrete improvement of existing antidetonation pot rubber bearing.Be sequentially set with pressure-bearing rubber tile, seal washer and middle steel liner plate at the bottom of the rectangle basin of undersetting body.The level that forms between the upper and lower bearing body by stainless steel liner plate, polyfluortetraethylene plate in being arranged at the bottom of the upper bracket body rectangle basin is slidingly matched relatively.Between upper bracket body basin type limit and middle steel liner plate upper end, be provided with the damping block structure.To be that elastomeric material and steel are compound be the energy-absorbing assembly of one to set damping block structure between crucial improvement was on upper bracket body basin type periphery and the middle steel liner plate.Above combined type vibration damping damping block structure in the external force of impact when the body of a bridge passes to the damping block structure by the upper bracket body, at first be that effect by steel evenly and rapidly is delivered to elastomeric material with external force, make that the whole elastomeric material integral body in the energy-absorbing assembly are out of shape uniformly, and produce maximum damping force.Reaction speed that damping force produced and buffering effect are significantly strengthened.The tangible technique effect of the utility model generation that Here it is.Further in the improvement project, can with steel further be improved to parts with energy-storage function, make to produce energy-absorbing effect when producing damping force, thereby weaken destructive power greatly bridge pier, play better damping effect.
