Replaceable limiting damper for pier beam connection
The invention relates to a replaceable limiting damper for pier-beam connection, and relates to the technical field of building bridges. Comprising an upper plate, a spiral energy dissipation ring, a spring reset ring, a lower plate, a supporting padstone and a beam bottom steel plate. The spiral energy consumption ring and the spring reset ring are uniformly distributed between the upper plate and the lower plate; the upper plate is connected with a beam bottom steel plate through first bolts; and the lower plate is connected with the supporting padstone through a ground anchor bolt. The spiral energy dissipation ring and the spring reset ring are arranged, under the condition that it is guaranteed that sliding of the plate type rubber support is not limited, beam body displacement is limited, beam body displacement or beam falling is avoided, it can be guaranteed that the limiting damper has good reset capacity and energy dissipation capacity, and post-earthquake damage is reduced.
本发明关于一种墩梁连接可更换限位阻尼器，涉及建筑桥梁技术领域。包括上板、螺旋耗能圈、弹簧复位圈、下板、支撑垫石和梁底钢板；螺旋耗能圈和弹簧复位圈均布在上板和下板之间；上板通过第一螺栓与梁底钢板连接；下板通过地锚螺栓与支撑垫石连接。本发明通过设置螺旋耗能圈和弹簧复位圈，在保证板式橡胶支座滑移不受限制的情况下限制梁体位移，避免梁体移位或落梁，并能够保证限位阻尼器具有良好的复位能力及耗能能力，降低震后损伤。
