Semi-active self-resetting tenon-and-mortise joint reinforcing device and reinforcing method
The invention discloses a semi-active self-resetting tenon-and-mortise joint reinforcing device and a reinforcing method.The semi-active self-resetting tenon-and-mortise joint reinforcing device comprises a wood beam combined hoop, a wood column combined hoop, a shape memory joint strip, a magneto-rheological damper and two symmetrical steel sparrow plates, and the wood beam combined hoop and the wood column combined hoop are each composed of a splicing and inserting module, a connecting shaft rod, an extending plate and a connecting plate; the two ends of the shape memory strips are respectively connected with the connecting plates of the wood beam combination hoop and the wood column combination hoop through split bolts; flat-head connectors at the two ends of the magneto-rheological damper are connected with extending plates of the wood beam combined hoop and the wood column combined hoop through high-strength bolts respectively; and the two symmetrical steel sparrow plates are mutually spliced and wrap the shape memory alloy plates and the magneto-rheological shock absorbers. According to the invention, the damping of the magnetorheological damper can be controlled at any time, and the shape memory alloy has superelasticity; therefore, the optimal damping effect and the self-resetting capability of the tenon-and-mortise joint when the tenon-and-mortise joint deals with different earthquake forces are enhanced.
本发明公开了一种半主动自复位榫卯节点加固装置及加固方法，包括木梁组合套箍、木柱组合套箍、形状记忆合条、磁流变减震器和两块对称钢质雀替板，所述的木梁组合套箍和木柱组合套箍都由拼插模块、连接轴杆、伸出板和连接板组成，形状记忆合条两端分别通过对拉螺栓与木梁组合套箍和木柱组合套箍的连接板相连接；磁流变减震器两端扁头连接头分别通过高强度螺栓与木梁组合套箍和木柱组合套箍的伸出板相连接；两块对称钢质雀替板相互拼合并将形状记忆合金板和磁流变减震器包裹其中。本发明通过磁流变减振器的阻尼任意时刻可控的特性和形状记忆合金的超弹性性能；以此来增强榫卯节点应对不同地震力大小时的最优减震效果和自复位能力。
