Bridge pier replaceable external soft steel bar damper and using method thereof
The invention discloses a bridge pier replaceable external soft steel bar damper and a using method thereof. The bridge pier replaceable external soft steel bar damper comprises two semicircular hooprings and a plurality of soft steel bars, wherein the two semicircular hoop rings are both arranged on the outer wall of a cylindrical bridge pier, the two semicircular hoop rings are in butt joint through bolts to form a circular ring used for being tightly attached to the outer wall of the cylindrical bridge pier, a plurality of penetrating holes are formed in the semicircular hoop rings, threaded sections are arranged at the two ends of the soft steel bars, the soft steel bars correspond to the penetrating holes in a one-to-one mode, one ends of the soft steel bars penetrate through the penetrating holes from one side of the semicircular hoop ring and extend to the other side of the semicircular hoop ring, nuts are arranged on the threaded sections extending to the other side of the semicircular hoop ring, and the other end is connected with a bearing platform of the cylindrical pier. The damper has the beneficial effects that rapid mounting and dismounting of the damper can be achieved, the damper is convenient to replace after being damaged by earthquakes, and meanwhile the damper has the advantages of being simple in structural form and low in manufacturing cost.
本发明公开了一种桥墩可更换外置软钢棒阻尼器及其使用方法，桥墩可更换外置软钢棒阻尼器包括半圆箍环，半圆箍环设有两个，两个半圆箍环均设于圆柱形桥墩外壁，且两个半圆箍环通过螺栓对接形成用于贴紧圆柱形桥墩外壁的圆环，半圆箍环上设有多个穿设孔；软钢棒，软钢棒设有多个，多个软钢棒的两端均设有螺纹段，多个软钢棒与多个穿设孔一一对应，且多个软钢棒的一端均从半圆箍环的一侧穿过穿设孔并延伸至半圆箍环另一侧，且延伸至半圆箍环另一侧的螺纹段上设有螺母，另一端与圆柱形桥墩的承台连接。本发明的有益效果是能够实现阻尼器的快速安装与拆卸，当遭遇地震破坏后，方便阻尼器的更换，同时，该阻尼器具有结构形式简单，造价低廉。
