Self-resetting high-damping rubber and SMA steel bar combined anti-falling beam device
The invention discloses a self-resetting high-damping rubber and SMA steel bar combined anti-falling beam device, and belongs to the technical field of bridge structures. The anti-falling beam devicecomprises an anti-drawing steel stop block arranged between a main beam and a bent cap and SMA steel bar components obliquely arranged on the two sides of the anti-drawing steel stop block. The SMA steel bar component comprises an SMA steel bar. An SMA steel bar upper sleeve box is arranged at the top end of the SMA steel bar; the top of the SMA steel bar is embedded in the accommodating cavity ofthe SMA steel bar upper sleeve box. A first energy dissipation pad is arranged on the inner wall of the accommodating cavity of the SMA steel bar upper sleeve box, a first initial gap is reserved between the first energy dissipation pad and the top end of the SMA steel bar, the bottom end of the SMA steel bar is fixedly embedded in an SMA steel bar lower anchor block, the SMA steel bar upper sleeve box is connected with the main beam, and the SMA steel bar lower anchor block is connected with the bent cap and the anti-drawing steel check block. According to the anti-falling beam device, smallearthquakes, medium earthquakes, large earthquakes and even over-expected earthquakes can be better protected, and effective self-repairing can be achieved after the earthquakes.
本发明公开了一种自复位的高阻尼橡胶与SMA钢棒联合的防落梁装置，属于桥梁结构技术领域。该防落梁装置包括设置在主梁和盖梁之间的抗拉拔钢挡块以及倾斜设置在抗拉拔钢挡块两侧设置的SMA钢棒构件；SMA钢棒构件包括SMA钢棒，SMA钢棒的顶端设有SMA钢棒上套箱，SMA钢棒的顶部嵌设在SMA钢棒上套箱的容纳腔内，SMA钢棒上套箱的容纳腔内壁上设有第一耗能垫，第一耗能垫与SMA钢棒顶端预留有第一初始间隙，SMA钢棒的底端嵌固在SMA钢棒下锚块内，SMA钢棒上套箱与主梁连接，SMA钢棒下锚块与盖梁和抗拉拔钢挡块连接。本发明的防落梁装置能够对小震、中震、大震甚至超预期地震进行更为完善的防护，且在震后能够有效自修复。
