Replaceable self-resetting energy dissipation damper
The invention relates to a replaceable self-resetting energy dissipation damper, and relates to the technical field of building bridges. Comprising an upper plate, a soft steel energy dissipater, a spring reset ring, a lower plate, a supporting padstone and a beam bottom steel plate. Wherein the soft steel energy dissipater 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. By arranging the soft steel energy dissipater and the spring reset ring, under the condition that it is guaranteed that sliding of the rubber support is not limited, beam body displacement is limited, too large beam body displacement or beam falling is avoided, it can be guaranteed that the limiting damper has good self-reset capacity and energy dissipation capacity, it is guaranteed that damage to a bridge is not too large under the earthquake effect, and the service life of the bridge is prolonged. And post-earthquake structural damage is reduced.
本发明关于一种可更换的自复位耗能阻尼器，涉及建筑桥梁技术领域。包括上板、软钢耗能器、弹簧复位圈、下板、支承垫石和梁底钢板；其中，软钢耗能器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承垫石连接。本发明通过设置软钢耗能器和弹簧复位圈，在保证橡胶支座滑移不受限制的情况下限制梁体位移，避免梁体位移过大或落梁，并且能保证限位阻尼器具有良好的自复位能力及耗能能力，保证地震作用下桥梁的损伤不致过大，降低震后结构损伤。
