Description
Technical Field
The utility model relates to the technical field of shock insulation supports, in particular to a composite shock insulation support with an automatic reset function, which consists of a lead rubber shock insulation support and an upper main sliding surface friction pendulum type shock insulation support.
Background
In the construction engineering and bridge engineering, the self-vibration period of the structure is prolonged and the earthquake energy is absorbed by arranging the shock-absorbing and isolating support with flexible deformation and damping performance between the foundation of the building and the upper structure, so that the earthquake reaction of the upper structure is reduced, and the purpose of reducing earthquake damage is achieved. The technology of the shock absorbing and insulating support has been widely accepted and used in engineering and academia with obvious shock absorbing effect and good economic applicability.
The friction pendulum vibration isolation support is a mature sliding vibration isolation support, and has stable hysteresis performance and automatic reset characteristics. The main principle of the shock insulation and isolation support is as follows: when the earthquake action of the friction pendulum vibration reduction and insulation support is small, the stability of the bridge is fully ensured by means of static friction force between the dead weight of the upper part and the bridge, and when the earthquake force is large, the support slides according to a certain period, so that the earthquake action of the upper structure of the bridge is not transmitted to the lower structure. The vibration period of the bridge structure is prolonged by designing the sliding surface, so that the amplification effect generated by the influence of the earthquake on the bridge structure is greatly reduced, the vibration isolation and energy absorption are realized by the friction generated between the sliding surface of the support and the sliding block, and the rigidity and period control can be realized by selecting a proper curve radius of the sliding surface. Meanwhile, the circular arc sliding surface of the friction pendulum vibration isolation can effectively control the displacement of the friction pendulum vibration reduction and isolation support, so that the friction pendulum vibration isolation support can recover to the original position after receiving the earthquake action.
The rubber shock insulation support is formed by alternately overlapping a plurality of layers of steel plates and rubber, and the steel plates are used as stiffening materials of the rubber support, so that the characteristic of smaller vertical rigidity of the rubber body is changed, the horizontal earthquake effect can be reduced, and larger vertical load can be borne. Since rubber is used as an elastomer, the energy consumption is insufficient, and therefore, a lead core is added into the support. The lead rubber vibration isolation support can bear the vertical load of the whole upper structure, prolong the structure period, provide certain damping, enable the earthquake force of the lower structure to be redistributed, prevent the displacement of the vibration isolation layer from being great, and have good vibration isolation effect. Meanwhile, the lead rubber shock insulation support has certain initial horizontal rigidity, and can resist the effects of load and braking load.
At present, the lead core rubber shock insulation support has static friction force between laminated rubber and a steel plate, so that the lead core rubber shock insulation support can not be well restored to the original position after an earthquake only by means of the attribute of the rubber, and the lead core rubber shock insulation support which is not restored can not fully exert the self function and deform when resisting the earthquake effect also has potential safety hazards on the vertical bearing capacity. Therefore, starting from the lead rubber vibration isolation support resetting device, the lead rubber vibration isolation support is improved, the automatic resetting friction vibration isolation support is additionally arranged, and the advantages of the friction vibration isolation support are fully exerted under the condition that the original functions of the lead rubber vibration isolation support are not changed, so that the lead rubber vibration isolation support can be automatically reset.
Disclosure of utility model

In order to achieve the above purpose, the present utility model provides the following technical solutions.
The utility model provides an automatic reset lead rubber composite shock insulation support, which comprises an upper connecting plate, a lower connecting plate, friction pendulum shock insulation units between the upper connecting plate and the lower connecting plate, and four lead rubber shock insulation supports arranged around the friction pendulum shock insulation units, wherein the upper end of the lead rubber shock insulation support is detachably and fixedly connected with the upper connecting plate, and the lower end of the lead rubber shock insulation support is detachably and fixedly connected with the lower connecting plate.

The number of the lead rubber shock insulation supports is four, and the lead rubber shock insulation supports are distributed uniformly and symmetrically along the friction pendulum shock insulation supports.

The working principle and the basic working process of the automatic reset lead rubber composite shock insulation support are as follows: in a normal use state, the friction pendulum vibration isolation unit and the lead core rubber vibration isolation support surrounding the friction pendulum vibration isolation unit provide vertical bearing for the upper structure together, so that the upper structure is stably supported; when an earthquake occurs, the whole support is repeatedly and laterally deformed, the period of the upper structure is prolonged, vibration isolation is realized, and meanwhile, the friction generated between the sliding surface of the support and the sliding block and the damping provided by the lead rubber vibration isolation support are used for jointly consuming energy brought by vibration through the friction vibration isolation unit in the process, so that vibration absorption is realized. When an earthquake stops, the displacement can be stopped firstly due to the fact that the damping of the lead core, the rubber and the steel plate is relatively large, and the support cannot be restored to the original shape due to the fact that the static friction force between the rubber and the steel plate is large. At the moment, the double-spherical-surface lining body of the friction pendulum vibration isolation unit still moves in the upper steel groove due to small self-damping, and self kinetic energy is consumed to offset static friction force between rubber and a steel plate so as to realize support reset. When the earthquake intensity is overlarge, the upper steel groove and the lower steel groove can clamp the double-spherical-surface lining body, and the lateral rigidity is improved to prevent the support from brittle failure, so that the building is protected.
