Energy consumption type beam falling prevention device
The invention discloses an energy consumption type anti-beam-falling device, and belongs to the technical field of bridge anti-seismic structures, by reasonably arranging the positions of a friction plate and an elastic support, an energy consumption structure of the device achieves a grading effect, the device can consume energy through friction during medium and small earthquakes, and the elastic support participates in deformation stress during large earthquakes, so that the anti-beam-falling effect is achieved. The device has a certain self-resetting function through the elastic support, and is reset after energy consumption is finished, so that the effect of long-term use is achieved, the elastic support is prevented from participating in energy consumption during small earthquakes through graded energy consumption, and the stability of a pier and a main beam connected with the whole anti-beam-falling device is improved.
本发明公开了一种耗能型防落梁装置，属于桥梁抗震结构技术领域，通过合理布置摩擦板以及弹性支撑的位置，使此装置的耗能结构实现分级效果，装置在中小震时可以通过摩擦耗能，而在大震时弹性支撑参与变形受力，此装置通过弹性支撑具有一定自复位功能，在耗能结束后进行归位，从而实现长久使用的效果，此装置通过分级耗能，避免弹性支撑在小震时参与耗能，提升整体防落梁装置连接的桥墩和主梁的稳定性。
