Multi-stage anti-seismic and anti-beam-falling device for prefabricated box girder
The invention relates to the field of bridges, and discloses a multi-stage anti-seismic and anti-beam-falling device for a prefabricated box girder, the anti-falling beam device is arranged between two adjacent box beams; the anti-beam-falling device comprises a barrel, a left pull rod, a right pull rod, a left magnetic assembly, a right magnetic assembly, a left limiting plate and a right limiting plate. The cylinder body is of a cylindrical structure, the two ends of the cylinder body are sealed through a left end cover and a right end cover respectively, the cylinder body is filled with damping liquid, the left magnetic assembly and the right magnetic assembly are in magnetic connection, and a memory alloy connecting rib is fixedly connected between the left limiting plate and the rightlimiting plate. By means of the multi-stage energy dissipation design, multi-stage earthquake resistance can be performed on the bridge, the device can adapt to the low-amplitude vibration effect during small earthquakes and can also adapt to dissipation of high-amplitude vibration during large earthquakes, the design cost is reduced, and the device better meets the actual requirement.
本发明涉及桥梁领域，具体公开了一种预制箱梁用多级抗震防落梁装置，所述防落梁装置设置在相邻两箱梁之间，所述防落梁装置包括筒体、左拉杆、右拉杆、左磁性组件、右磁性组件、左限位板以及右限位板，所述筒体呈圆筒状结构且其两端分别通过左端盖和右端盖封闭，所述筒体内填充有阻尼液，所述左磁性组件和右磁性组件相互之间磁性连接，所述左限位板和右限位板之间固定连接有记忆合金连接筋。本发明装置通过多级的耗能设计，可以对桥梁进行多级抗震，既可以适应于小震时低幅振动作用，也能适应于大震时的高幅振动的耗散，降低了设计成本，使其更符合实际需要。
