Fabricated self-resetting energy dissipation bridge stop block
The invention discloses an assembly type self-resetting energy dissipation bridge stop block which comprises a stop block body, the stop block body is connected to extending arms on the two sides of a cover beam through prestressed steel bars, a damper is connected between the side face of the stop block body and the side face of a cover beam body, and a rubber pad is connected to the upper portion of the side face of the stop block body and arranged on the side face of a beam body above the cover beam. A fixed check block is replaced by the fabricated check block, the check block is arranged at the bent cap extending arm, the check block is connected with the bent cap extending arm through the prestressed steel bar, and the disc spring is arranged at the anchoring position of the top end of the prestressed steel bar, so that the prestressed steel bar is tensioned, and the installation stability of the check block is guaranteed; the lower part of the side face of the check block is connected with the bent cap main body through the U-shaped damper; a rubber pad is arranged at the upper part of the baffle block; and the damper can drive the check block to reset, residual deformation caused by vibration is reduced, impact of an upper beam body structure on the check block is buffered, and the self-resetting capacity of the whole anti-seismic check block system is improved.
本发明公开了一种装配式自复位耗能桥梁挡块，包括：挡块，挡块通过预应力钢筋连接于盖梁两侧的伸臂处，挡块侧面与盖梁主体侧面之间连接有阻尼器，挡块侧面上部连接有橡胶垫，橡胶垫设置于盖梁上方的梁体侧面。本发明采用装配式挡块替代固定挡块，将挡块设置于盖梁伸臂处，通过预应力钢筋将挡块与盖梁伸臂连接，预应力钢筋顶端锚固处设置碟簧，实现对预应力钢筋的张拉，保证挡块的安装稳定性，挡块侧面下部通U形的阻尼器与盖梁主体连接，挡块侧面上部设置橡胶垫；有效减少挡块的横向位移，阻尼器能够带动挡块复位，减少受震动的残余变形，缓冲上部梁体结构对挡块的撞击，提升整个抗震挡块系统的自复位能力。
