Compression-shear separated variable-stiffness vibration isolation support and manufacturing method thereof
The invention provides a compression-shear separated variable-stiffness vibration isolation support and a manufacturing method thereof. The support comprises an upper support plate, a lower support plate and a vibration isolation assembly arranged between the upper support plate and the lower support plate. The vibration isolation assembly comprises a vertical vibration isolation assembly and a horizontal vibration isolation assembly. The vertical vibration isolation assembly comprises long vertical springs, short vertical springs, a damper, a limiting block groove and a limiting block. The horizontal vibration isolation assembly comprises a core steel rod, a steel sleeve and a pre-tension sleeve piece. The pre-tension sleeve piece comprises a sliding ring, a unit of shape memory alloy rods and a unit of locking nuts. The support is simple in structure and simple in machining technique, all the parts and components can be obtained and assembled easily, installation is convenient, and the cost performance is high. All the parts of the support are made of metal materials and are good in durability. Meanwhile, the stress path is clear, the vertical force and horizontal force are borneby different parts of the support, compression-shear separation can be effectively achieved. The energy-dissipating capacity and the self-resetting capacity are high. The vertical and horizontal rigidity of the support is adjustable and controllable, and vibration isolation and displacement constrain under different earthquake motions are achieved.
一种压剪分离式变刚度隔震支座及其施工方法，包括支座上板、支座下板和设置在两者之间的隔震组件，隔震组件包括竖向隔震组件和水平隔震组件，竖向隔震组件包括长竖向弹簧、短竖向弹簧、阻尼器、限位挡槽和限位挡板，水平隔震组件包括核心钢棒、钢套筒和预张拉套件，预张拉套件包括滑动圆环、一组形状记忆合金棒和一组锁紧螺母。本发明构造简单、加工工艺简洁、各部件易于获取和装配，安装方便，性价比高。支座各部分均采用金属材料耐久性好。同时，受力路径明确、竖向力和水平力由支座的不同部分分开承担，可以有效实现压剪分离，耗能能力和自复位能力强。支座的竖向和水平向刚度均可调、可变、可控，从而实现不同地震动下的隔震和位移限制。
