The function-separated self-resetting friction cable energy-dissipating shock-absorbing support includes a horizontal tube. The front and rear ends of the horizontal tube are respectively fixedly connected to the fixed piers through brackets. The inner concave surface faces the horizontal tube, the length direction of the arc-shaped plate is parallel to the length square of the horizontal tube, and a plurality of evenly distributed through holes are opened on the side of the horizontal tube corresponding to the middle of the inner concave surface of the arc-shaped plate. The directions are evenly distributed, and the interior of the horizontal tube is provided with a rotating shaft, which is coaxially arranged with the horizontal tube. The front and rear ends of the rotating shaft are movably connected with the inside of the horizontal tube through bearings. The inner side of the arc-shaped plate is fixedly connected, the inner end of the insertion rod and the side of the rotating shaft are hingedly connected by a connecting rod, the left and right sides of the horizontal tube are symmetrically provided with connecting blocks, and the connecting blocks are fixedly installed on the bottom of the beam body. The overall periphery composed of shaped plates is wound with friction cables. The invention is easy to install and facilitates follow-up maintenance work.
Description
Technical field [0001] The invention belongs to the field of earthquake resistance of building structures, in particular to a function-separated self-resetting friction cable energy-consuming and shock-absorbing support. Background technique [0002] In order to reduce the seismic response of continuous girder bridges and improve the overall seismic performance of continuous girder bridges, the fixed piers usually adopt shock-absorbing and seismic isolation supports for continuous girder bridges, such as lead rubber bearings, friction pendulum bearings, etc. However, the above damping measures did not change the separation of the vertical bearing function of the support from the horizontal energy absorbing and damping functions. Many earthquake disaster inspections found that the above conventional shock-absorbing and isolating bearings were mostly damaged due to excessive horizontal relative displacement under the action of strong earthquakes. Not only did they lose the function...
