Description

Oblique orthogonal combination vibration isolation support with vibration and vibration double control Technical Field The invention relates to the technical field of civil engineering damping structures, in particular to a diagonal orthogonal combination vibration isolation support with vibration and shock dual control. Background The prior more and more buildings, structures, equipment and the like have remarkable double requirements on the adopted vibration isolation (vibration) support products, namely the support has good bearing and deformation capacity under the vertical gravity action and the earthquake action of the upper structure, and also has good three-dimensional vibration isolation function under the environment vibration action, namely the vibration and vibration double control function. However, to realize the vibration dual control function, the existing mature vibration isolation (vibration) support still has the following defects: 1. The existing mature structural shock insulation rubber support has only a single function of isolating horizontal earthquake action and cannot isolate environmental vibration action. For example, a natural rubber vibration isolation support (LNR support), a lead rubber vibration isolation support (LRB support), a high damping rubber vibration isolation support (HDR support), an elastic sliding plate vibration isolation support (SLB support) and the like have overlarge vertical rigidity, so that the vibration isolator only has a horizontal vibration isolation function and does not have a three-dimensional vibration isolation function. In order to improve the function of the rubber support for isolating the environmental vibration, the academic and engineering circles develop a thick lamination (thick meat type) rubber support, but the method reduces the vertical bearing capacity, the horizontal deformation capacity and the stability of the rubber support, influences the functions of bearing and isolating the earthquake, and cannot truly realize the vibration double control. 2. The existing mature steel spring support only has the function of isolating environmental vibration, and cannot isolate the horizontal earthquake effect. The steel spring does not have large deformation bearing capacity during horizontal earthquake action, damping required by vibration isolation cannot be provided, a damper is required to be additionally arranged, and in addition, the steel spring is relatively expensive in manufacturing cost, so that the construction cost is remarkably increased. 3. In the prior art, a series combined vibration isolation (vibration) support is adopted, for example, a support product adopting a mode of combining a rubber support with a steel spring, combining a traditional rubber support with a thick laminated rubber support and the like is difficult to coordinate different design surface pressures and bearing capacity parameters of different supports connected in series during design, and the vibration isolation (vibration) support is mainly used for isolating earthquakes or mainly used for isolating environmental vibrations, so that the vibration isolation (vibration) function on the other side is sacrificed, and the vibration and vibration double control cannot be really realized. Disclosure of Invention Aiming at the technical problems in the prior art, the invention aims to provide the inclined orthogonal combined vibration isolation support with vibration dual control, which solves the technical contradiction between the vertical flexibility and the horizontal stability of the vibration isolation support, reduces the vertical rigidity of the rubber support, and can keep the vertical bearing and horizontal large deformation capacity at the same time, thereby realizing the vibration dual control. In order to achieve the above purpose, the invention adopts the following technical scheme: The obliquely-arranged orthogonal combined vibration isolation support comprises an upper connecting plate, a middle connecting plate and a lower connecting plate which are sequentially distributed from top to bottom, wherein at least two inclined plane pedestals which are distributed side by side are installed at the bottom of the upper connecting plate, at least two inclined plane pedestals which are distributed side by side are installed at the top and the bottom of the lower connecting plate, at least one inclined plane pedestal is installed at the top and the bottom of the middle connecting plate, the two inclined plane pedestals which are located on the upper connecting plate are fixedly connected with the inclined plane pedestals which are located on the top of the middle connecting plate respectively through two vibration isolation parts, the two inclined plane pedestals which are located on the lower connecting plate are fixedly connected with the inclined plane pedestals which are located on the bottom of the middle connecting plate respectively, the two vi
