Replaceable shape memory alloy composite vibration-isolating support base
The invention relates to a replaceable shape memory alloy composite vibration-isolating support base. The replaceable shape memory alloy composite vibration-isolating support base comprises an upper connecting plate, a lower connecting plate, a laminated rubber support base and a shape memory alloy stranded wire, namely an SMA stranded wire, wherein the upper connecting plate and the lower connecting plate are separately fixed with upper and lower surfaces of the laminated rubber support base through fixed bolts; high-strength nuts are longitudinally welded inside the upper connecting plate and the lower connecting plate at front and rear sides of the laminated rubber support base; the shape memory alloy strained wire is fixed after sequentially passing through one high-strength nut on theupper connecting plate and the lower connecting plate, so that the shape memory alloy strained wire defines an M type. The shape memory alloy strained wire has higher energy dissipating ability and self-returning ability, and can effectively control residual deformation after earthquake of the support base and the structure; and compared with a conventional rubber support base, the replaceable shape memory alloy composite vibration-isolating support base is obviously improved in resistance to tension, can resist relatively great vertical deformation, and is convenient in mounting and dismounting.
本发明涉及一种可更换的形状记忆合金复合隔震支座，包括上连接板、下连接板，叠层橡胶支座和形状记忆合金绞线即SMA绞线，所述上连接板和下连接板分别通过固定螺栓与叠层橡胶支座上下表面固定在一起；所述叠层橡胶支座前后两侧的上连接板、下连接板内侧沿纵向焊接有高强螺母，形状记忆合金绞线依次穿过上连接板、下连接板上的一个高强螺母后固定，使形状记忆合金绞线构成“M”型。形状记忆合金绞线具有更高的耗能能力和自复位能力，能有效控制支座、结构震后的残余变形；较传统橡胶支座，抗拉能力明显提高，能抵抗较大的竖向变形，且安装、拆卸方便。
