Description

A three-way self-resetting energy-dissipating shock-isolation bearing

technical field

The invention relates to a three-way self-resetting energy-dissipating shock-isolation support, which is applied in the technical field of building shock-isolation supports.

Background technique

As we all know, at present, modern seismic isolation technology has been widely used in various fields of civil engineering. Compared with earthquake resistance, seismic isolation structures have gained a lot of attention due to their excellent shock absorption effect, safety, durability, economy and practicability. It is widely recognized in the industry that most of the previous seismic isolation designs did not take into account the impact of vertical seismic waves on building structures. The impact of seismic waves on building structures has two directions of horizontal seismic components, one vertical seismic component and three rotational seismic components. For the safety of structures, vertical seismic components are often not negligible. With the maturity of energy dissipation and shock absorption technology, more and more energy dissipation and shock absorption concepts are constantly appearing in people's field of vision. However, the research on vertical shock-isolation bearings is still mainly concentrated on the traditional disc spring, the research space and scope are generally small, and the application in actual engineering is even less.

Traditional rubber isolation bearings have the disadvantages of poor deformation ability and weak self-resetting ability, and are prone to large plastic deformation under strong earthquakes, resulting in overturning and damage to engineering structures; in addition, weak self-resetting ability will also make the use of seismic isolation bearings Reduced lifespan. And after the earthquake, the seismic isolation support was damaged, and the overall replacement cost was too high. Therefore, post-earthquake repair is undoubtedly very important.

A utility model patent with the notification number CN210032111U discloses a shock-isolation rubber bearing device with a tensile function, including an upper rail system, a lower rail system, an upper vibration-isolation rubber bearing, a lower vibration-isolation rubber bearing, and an upper guide rail. The system and the lower rail system are decoupled from the upper vibration-isolation rubber bearing and the lower vibration-isolation rubber bearing respectively, and are not involved in each other. In addition, the upper rail system and the lower rail system can slide vertically through the guide rails and sliders set on them. , which can not only ensure the arbitrary horizontal movement of the upper isolation rubber bearing and the lower isolation rubber bearing, effectively reduce the seismic effect of the isolation structure, but also provide greater tensile strength to prevent the structure from being damaged by the upper isolation rubber The support or the lower shock-absorbing rubber support is pulled out to provide a certain safety reserve. Although this kind of seismic isolation support considers vertical seismic isolation, it does not consider the influence of multi-directional horizontal earthquake action. In addition, the support lacks self-resetting ability and is not easy to repair after the earthquake.

Therefore, how to provide a multi-directional energy-dissipating and shock-absorbing member with high energy consumption efficiency, remarkable shock isolation effect, and green economy is an urgent problem to be solved by those skilled in the art.

Working principle of the present invention:

The top plate 30 on the upper part of the support is connected with the column bottom of the building, and the top plate 30 is fixed by using reserved bolt holes, the first bottom plate 1 below the support is connected with the foundation, and the first bottom plate 1 is fixed by bolts through the reserved bolt holes;

Under the earthquake, there are two directions of shear waves and one longitudinal wave, which are transmitted to the first base plate 1 of the support through the foundation at the bottom. Since the first base plate 1 and the second base plate 2 have a displacement in one direction, this direction is set to In the X direction, the movement of the first bottom plate 1 results in relative displacement. The first bottom plate 1, the second bottom plate 2, the first conduit 5, the first return spring 6 and the first stopper 7 constitute the energy dissipation in the X direction. The second bottom plate 2 snapped into the first groove 101 of the first bottom plate 1, and the viscous medium and seal filled in the first groove 101 after the assembly is completed (the bottom groove plate of the second bottom plate 2 has a through hole, and the first bottom plate 1 and the second bottom plate 2 are staggered, through the relative staggering of the viscous medium and the inner wall of the hole to consume energy), the viscous medium can be selected from hydraulic oil, silicone oil, silicon-based rubber or special suspension, preferably using dimethyl Silicone oil, through the staggering of the first bottom plate 1 and the second bottom plate 2 in the X direction, performs viscous energy dissipation, and the first return spring 6 performs the reset function and stores energy during earthquakes. This is the first stage of energy consumption and shock isolation , for the seismic wave in the X direction;

Under the action of an earthquake, the seismic wave in the X direction is isolated and energy-dissipated by the structure of the first base plate 1 and the second base plate 2, and the direction of the seismic wave in the other direction is set to the Y direction, and the Y seismic wave is transmitted to the second base plate 1 through the first base plate 1. Bottom plate 2, because there is a Y-direction misalignment allowance between the third bottom plate 8 and the second bottom plate 2, the second bottom plate 2 will move relative to the third bottom plate 8, and the second bottom plate 2 and the third bottom plate 8 use the second groove 201 for clamping, while using the second return spring 11, the second conduit 10, and the second stopper 12 to guide, fix, and reset, add friction plate material in the second groove 201, and use the second bottom plate 2 and the first The staggering of the three bottom plates 8 performs frictional energy consumption, and the second return spring 11 performs reset and energy storage during earthquakes. At this stage, the seismic energy in the Y direction is weakened, and the energy consumption isolation in the two transverse seismic wave directions is completed so far;

The relative displacement up and down of the inserting rod 16 will cause the movement of the fourth connecting rod 28, and then the slider 21 will move on the guide rail 19. Moving in the horizontal Y direction, a part of the slider 21 is in the third groove 801 provided on the third bottom plate 8, which can increase a part of the frictional energy consumption. The other end of the slider 21 is connected with the sleeve rod 22, and the movement of the slider 21 causes The sleeve rod 22 moves, and then pushes and pulls the viscous medium in the horizontal cylinder 23, and the porous circular plate 231 is fixed in the horizontal cylinder 23, so as to dissipate viscous energy, so the vertical relative movement will be transformed into a sliding medium. The horizontal movement of the block 21 performs frictional and viscous energy consumption, and at the same time has the effect of displacement and speed amplification.
