Description
Technical Field
The invention relates to the technical field of building shock isolation, in particular to a shock-absorbing double-control support adopting staggered lamination of a shock-absorbing plate and perforated rubber.
Background
Firstly, in order to ensure the bearing stability of the existing building shock-insulation rubber support conforming to national standards and industrial regulations, a rubber layer of the existing building shock-insulation rubber support needs to adopt thin laminated layers, a first shape coefficient S1 (the ratio of the effective bearing area of a single rubber layer in the support to the surface area of the free side of the single rubber layer) is generally larger than 15, and a second shape coefficient S2 (the ratio of the diameter or the effective width of an internal rubber layer to the total thickness of the internal rubber) is generally larger than 5, so that the vertical rigidity of the support is very large and the support does not have a vertical shock-insulation function;
secondly, in the technical research and development field, in order to improve the vertical vibration isolation performance of the rubber vibration isolation support, the mainstream method at present is to simply increase the thickness (thick lamination and thick flesh type) of the rubber layer to increase the surface area of the free side of the single-layer rubber, but the method has very limited reduction of the vertical rigidity of the support, and simultaneously can cause the first shape coefficient S1 of the support to be obviously reduced, even cause the second shape coefficient S2 of the support to be also obviously reduced, so that the lateral buckling prevention stability and the bearing capacity of the support are greatly reduced, the vibration of subway and rail transit cannot be efficiently isolated, the amplification of the vibration component of the low-frequency section of the support can be caused, the vertical vibration isolation function is lost, and the popularization is difficult.
Furthermore, another way of improving the vertical vibration isolation performance of the conventional vibration isolation support is to simply connect the conventional vibration isolation support and the vertical vibration isolation element in series, and a vertical steel spring is usually directly additionally arranged on the upper part or the lower part of the vibration isolation support, however, the efficient vertical vibration isolation function cannot be realized by the method. The damping of the steel spring is far lower than that of a rubber material, so that the damping requirement of vertical vibration isolation is difficult to meet, and the steel spring has a local vibration mode due to large mass density, so that external vibration corresponding to the frequency of the steel spring can be smoothly transmitted to the upper part through the steel spring, a high-frequency passing phenomenon is formed, and the vibration isolation effect is reduced. In addition, the design height of the steel spring element is generally very high, so that the overall appearance of the support after being connected in series is too thin, the support is easy to have a lateral buckling form under the action of a lateral earthquake, and the structural hidden danger exists.
In conclusion, in the present stage, an elastic sliding plate shock insulation support with a vibration and shock double-control function is urgently needed to be developed, so that the elastic sliding plate shock insulation support has the characteristics of low vertical rigidity, good vibration isolation effect, high vertical damping and good lateral bending resistance stability, and meets the urgent need of the current market.
