Self-resetting SMA-three-dimensional shock insulation lead core rubber support
The invention relates to the technical field of underground structure seismic resistance, in particular to a self-resetting SMA-three-dimensional seismic isolation lead core rubber support. The support is installed at the top of a center pillar in an underground space and comprises an upper connecting plate fixed to the lower surface of a top plate beam, a middle connecting plate is arranged below the upper connecting plate, force is transmitted to a rubber damping support below the upper connecting plate through a dowel bar, a middle protruding shaft and an SMA spring combined component, and the support is formed by combining a rubber laminated steel plate, a lead core and a steel block. The upper portion of the rubber laminated steel plate is fixed to the middle connecting plate, and the lower portion of the rubber laminated steel plate is fixed to the lower connecting plate. A fireproof and anti-aging rubber protective sleeve is arranged on the periphery of the rubber laminated steel plate; in addition, SMA wires are arranged between the middle connecting plate and the lower connecting plate, and the tensile strength is adjusted through double nuts and bolts. A traditional horizontal rubber support and a vertical memory alloy-lead damping technology are fused, the stability of the support and the structure is improved, and the damping effect of a structural system is obvious under the action of multidirectional earthquakes.
本发明涉及地下结构抗震技术领域，具体涉及一种自复位SMA‑三维隔震铅芯橡胶支座；该支座安装于地下空间中柱柱顶，包括固定于顶板梁下表面的上连板，下设中连板，并通过传力杆、中凸轴与SMA弹簧组合构件将力传至下方橡胶阻尼支座，支座由橡胶叠合钢板、铅芯及钢块组合构成；橡胶叠合钢板上部固定于中连板，下部固定于下连板，下连板固定于中柱顶部；橡胶叠合钢板外围有防火防老化的橡胶保护套；此外，中连板与下连板间布置有SMA丝，并通过双螺母螺栓调节拉伸强度；本发明将传统的水平橡胶支座与竖向记忆合金‑铅阻尼技术融合，不仅提高了支座与结构的稳定性，还在多向地震作用下使结构体系的减震效果明显。
