Multi-stage energy dissipation self-resetting and limiting integrated device
The invention discloses a multi-stage energy dissipation self-resetting and limiting integrated device, and belongs to the technical field of bridge seismic strengthening, a first-stage energy dissipation structure is formed through a friction plate arranged between an inner cylinder and an outer cylinder, further, a secondary energy dissipation part of the device can dissipate energy for large displacement caused by a large earthquake, and the energy dissipation effect is good. After the outer cylinder and the inner cylinder consume friction stress, the outer cylinder and the inner cylinder are continuously pulled or pressed, after the inner cylinder and the outer cylinder conduct certain displacement, the check blocks abut against the limiting structures of the inner cylinder and the outer cylinder, at the moment, the two check blocks are pushed to be away from each other, the steel strand is pulled, the disc spring is pressed, and a second-stage energy dissipation structure is formed; the disc spring can support the inner core to realize self-resetting; according to the device, the length of the device is changed excessively to avoid the situation that the relative distance between the pier and the main beam is too long or too short due to excessive change of the length of the device, the device can cope with displacement of different piers and main beams through a multi-stage energy dissipation structure, the device is high in energy dissipation capacity and has certain self-resetting capacity, and the connecting capacity of the device is ensured.
本发明公开了一种多级消能自复位与限位一体化装置，属于桥梁抗震加固技术领域，通过内筒和外筒之间设置的摩擦板，形成第一级消能结构，进一步的，此装置的次级消能部即可对大震带来的较大位移进行消能，当外筒和内筒在消耗摩擦应力后，继续受拉或受压，内筒和外筒在进行一定位移后，挡块抵在内筒和外筒的限位结构上，此时均会推动两块挡块相互远离，使钢绞线受拉，碟簧受压，形成二级消能结构，二级消能结构在位移因素消失后，碟簧会支撑内芯，实现自复位；以避免此装置长度的过度变化，导致桥墩和主梁相对距离过远或过近，此装置通过多级耗能的结构，以应对不同的桥墩和主梁的位移，装置消能能力较高，具有一定自复位能力，确保装置的连接能力。
