The support is a sliding friction shock insulation support, and has the advantages of large horizontal slippage and capability of limiting horizontal displacement; the main disadvantages include: 1) under the action of an external force vertical to the translation, the vertical displacement of the upper sliding plate and the lower sliding plate of the support cannot be controlled; 2) after the horizontal displacement occurs, the original position can not be automatically recovered; 3) the requirement on the flatness of the mounting plane is high.

2. A direct-sliding friction sliding support (patent number: ZL 01212976.3) is composed of an upper sliding plate and a lower sliding plate. The upper and lower sliding plates are provided with a basic film layer on one surface of the steel plate base material, the basic film layer is covered with a composite film layer, and the composite film layers of the upper and lower sliding plates are butted together. The support is a sliding friction shock insulation support, and has the advantages of large horizontal slippage, large bearing capacity and no edge effect of the upper and lower sliding plates under the action of long-term load; the main disadvantages include: 1) under the action of an external force vertical to the translation, the vertical displacement of the upper sliding plate and the lower sliding plate of the support cannot be controlled; 2) after the horizontal displacement occurs, the original position can not be automatically recovered; 3) the requirement on the flatness of the mounting plane is high.

One end of the vibration control connecting piece is connected with the upper friction sliding plate, and the other end of the vibration control connecting piece is connected with the middle sliding plate into a whole. The support is a sliding friction shock insulation support, and has the advantages that the horizontal slippage and the vertical displacement between the upper friction sliding plate and the lower friction sliding plate can be controlled, and the stability of horizontal slippage is improved; the main disadvantages include: 1) the middle friction sliding support piece and the middle sliding plate are mutually limited, so that the provided displacement is limited, and the use is influenced, 2) the horizontal reset component is not favorably arranged due to insufficient displacement, 3) the components formed by the support are all in rigid connection, and when rubber pads are respectively adopted on the upper surface and the lower surface of the upper friction sliding plate and the lower friction sliding plate, the service life is influenced.

5. The laminated rubber support is composed of an upper connecting steel plate and a lower connecting steel plate, wherein a thin rubber plate and a thin steel plate are alternately overlapped and a lead core rod is added; the support is a vibration damping support, and has the advantages that the acting force period is prolonged through the horizontal deformation of rubber, so that the force acting on a connected object is reduced; because of the characteristics of the rubber, the support has the function of resetting after horizontal displacement, the steel plate in the lamination can change the rigidity of the support, the lead core rod can increase the damping and reduce the deformation, and the laminated rubber support is widely applied to various fields; the main disadvantages include: 1) the laminated rubber support has a vibration damping effect, but does not have the vibration isolation effect of a sliding friction support and a rolling friction support, the acting force after vibration damping cannot be determined on a same numerical value, and the reduced acting force after vibration damping of the laminated rubber support also correspondingly changes along with the change of the acting force larger than the initial horizontal displacement; 2) due to the adoption of rubber, the problems of corrosion, fire resistance and unstable performance are caused, and the time effect forms the threat to the service life of the laminated rubber support; 3) the hysteresis curve under displacement and acting force is not stable as reflected by test data.

6. The rubber and steel plate sliding support consists of upper sliding plate and lower sliding plate.

Its advantages are vibration isolating and damping function and reset function; the main disadvantages include: 1) the relative vertical displacement of the upper sliding part and the lower sliding part can not be controlled, 2) the interference of vertical vibration to horizontal displacement exists, and 3) the instability of sliding rigidity and the vulnerability of a sliding friction surface are caused by a curve sliding surface.

8.

One end of the movement control blocking body is connected with the lower support moving body, and the other end of the movement control blocking body supports the upper moving body and is connected with the upper anti-disengagement movement control moving body. One end of the anti-separation connecting piece is connected with the upper moving body, penetrates through the upper anti-separation control moving body and the anti-separation plate, and the other end of the anti-separation connecting piece is connected with the lower anti-separation moving body. The movable anti-separation support moves in any direction in a determined plane and cannot be separated in the moving process; displacement and displacement in a direction inconsistent with the moving direction can be limited, and the stability of the moving process is improved; and the structure is simple. There are disadvantages: 1) the support adopts a steel member with high rigidity to control vertical displacement, so that a large vertical impact effect is generated on the support, and objects connected by the support are not protected; 2) the vibration control and damping effect in any direction cannot be achieved, and an auxiliary component is often required to be arranged outside the support; 3) the problem of additional deformation of the support caused by uneven distribution of vertical load on a plane cannot be solved.
