Building shock insulation rubber support based on phononic crystals
The building shock insulation rubber support comprises an upper pre-buried steel plate and a lower pre-buried steel plate, an upper steel plate is installed at the bottom of the upper pre-buried steel plate, a lower steel plate is installed at the top of the lower pre-buried steel plate, a stainless steel plate is fixedly connected to the bottom of the upper steel plate, and a shock absorption supporting plate is erected at the bottom of the stainless steel plate; steel plate layers and periodic damping layers are alternately stacked between the damping supporting plate and the lower steel plate, damping lead cores are fixed to the middle of the bottom of the damping supporting plate and the middle of the top of the lower steel plate, and the damping lead cores penetrate through the middles of the steel plate layers and the periodic damping layers. The periodic damping layer is composed of a plurality of damping cells, each damping cell comprises a base plate, a coating and a scatterer are sequentially arranged at the center position of the upper surface of each base plate from bottom to top, and a coating and a scatterer are sequentially arranged at the center position of the lower surface of each base plate from top to bottom. A periodic damping structure similar to a photonic crystal is applied, the low-frequency vibration isolation effect of the vibration isolation support is effectively improved, and the vibration isolation support is stable in performance, simple in structure, easy to install and worthy of popularization.
本发明是一种基于声子晶体的建筑隔震橡胶支座，包括上预埋钢板、下预埋钢板，上预埋钢板底部安装有上钢板，下预埋钢板顶部安装有下钢板，上钢板底部固接有不锈钢板，不锈钢板底部搭设有减震支撑板，减震支撑板与下钢板之间交替叠放有钢板层和周期减震层，减震支撑板底部中间位置与下钢板顶部中间位置固定有减震铅芯，减震铅芯从钢板层、周期减震层的中部穿过。周期减震层是由若干个减震元胞组成，每个减震元胞包括基板，基板上表面中心位置从下到上依次设有覆层、散射器且下表面中心位置从上到下依次设有覆层、散射器。本发明应用类似声子晶体的周期减震结构，有效提升了隔震支座隔绝低频震动的效果，性能稳定，结构简单，易于安装，值得推广。
