Description
Technical Field
The utility model belongs to the technical field of the support, concretely relates to damping support.
Background
Recent earthquake disasters show that once an earthquake causes serious damage to a traffic line, possible lives and properties and indirect economic losses are more and more huge. The bridge is used as an important throat of a traffic network, and the anti-seismic performance of the bridge is related to whether the whole traffic life line is smooth or not, so that the speed of anti-seismic disaster relief and post-disaster reconstruction is influenced. Therefore, the study of seismic resistance of bridge structures has been a hot issue of attention of scholars.
The bridge seismic design method goes through the traditional strength seismic theory, ductility seismic theory, seismic reduction and isolation technical theory and other stages. The seismic isolation and reduction technology is a simple, convenient, economical and advanced engineering seismic resistance means. By selecting a proper seismic isolation and reduction device and a proper setting position, the internal force distribution of the structure can be effectively controlled.

The basin-type rubber support uses the elastic rubber block in the semi-closed steel basin cavity, has the property of fluid in a three-dimensional stress state, and realizes the rotation of an upper structure; meanwhile, the horizontal displacement of the upper structure is realized by the low friction coefficient between the polytetrafluoroethylene plate on the middle sliding plate II and the stainless sliding plate II on the upper seat plate. But the shock absorption is realized through friction energy consumption, the shock absorption device can only adapt to the earthquake with smaller magnitude of earthquake, and the shock absorption requirement can not be met for the earthquake with larger magnitude of earthquake.
The lead core rubber support is formed by inserting one or more lead zinc into a common plate type rubber support, and the addition of the lead zinc increases the horizontal shearing resistance of the support and also enables the damping performance of the support to be well improved. The lead-zinc rubber support bears vertical load and horizontal load, so that lead and zinc generate hysteresis damping plastic deformation, and horizontal restoring force is provided through rubber. But the horizontal shear resistance of support has been increased in the addition of plumbous zinc, and when at ordinary times on-vehicle atress, because the atress is less, plumbous zinc rubber support is exactly a fixing support this moment, and rubber and plumbous zinc are all fixed, so rubber support can't adapt to the shock attenuation demand when at ordinary times on-vehicle atress.
In conclusion, the rubber support in the prior art does not have the rubber support which can meet the damping requirement of the vehicle-mounted earthquake with the large shock level at ordinary times, so that the damping support is provided.

It should be noted that, in the initial state, the first elastic body 3 is not in contact with the second elastic body 4, and the second elastic body 4 is not in contact with the limiting mechanism 5, so that a sliding space is provided for the second elastic body 4 when the first elastic body 3 deforms; in a similar way, the second elastic body 4 is not contacted with the limiting mechanism 5, and a sliding space is provided for the sliding of the second elastic body 4.
The working principle is as follows: the device is arranged between a pier and a bridge floor, the bridge floor can be subjected to slight vibration force under the vehicle-mounted condition, at the moment, the first elastic body 3 is subjected to damping deformation, and the damping deformation consumes vibration kinetic energy, so that the bridge floor is kept stable; under the action of other external forces, such as wind load or earthquake, there are two damping modes: (1) the first elastic body 3 deforms and absorbs shock, (2) the first elastic body 3 and the second elastic body 4 deform and absorb shock together; when the first elastic body 3 and the second elastic body 4 deform and absorb shock together, the first elastic body 3 and the second elastic body 4 both have damping deformation, the damping deformation consumes shock kinetic energy, and the shock absorption effects of the first elastic body 3 and the second elastic body 4 can achieve a superposed effect, so that the shock absorption device can adapt to shock absorption of larger shock force.
It should be noted that, in the prior art, if an elastic body with large damping is directly arranged, under the condition of normal vehicle-mounted, because the force is too small, the elastic body with large damping cannot deform and absorb shock, for example, if an elastic body with small damping is arranged, when the wind load and the earthquake force are large, the vibration kinetic energy consumed by the deformation of the elastic body with small damping is small, and the shock absorption effect is poor.
In the utility model, the elastic body is set as the first elastic body 3 and the second elastic body 4, when the force is small, the first elastic body 3 can deform and absorb the shock, when the force is large, the first elastic body 3 can independently absorb the shock, along with the continuous increase of the force, the first elastic body 3 and the second elastic body 4 can deform and absorb the shock together, and the first elastic body 3 and the second elastic body 4 deform together, so that the larger vibration kinetic energy can be consumed, and the better shock absorption effect can be achieved; therefore, the support can be applied to large-range shock absorption.
