Anti-seismic energy dissipation column using piezoelectric material and construction method of anti-seismic energy dissipation column
The invention discloses an anti-seismic energy dissipation column using a piezoelectric material, which comprises an aluminum column, a piezoelectric anti-seismic structure is sleeved in the aluminum column, the piezoelectric anti-seismic structure comprises a power supply and a plurality of first piezoelectric circular rings, a second piezoelectric circular ring is inserted between the adjacent first piezoelectric circular rings, the positive and negative electrodes of the power supply are respectively connected with a wire, and the first piezoelectric circular ring and the second piezoelectric circular ring are connected with the aluminum column. One end of the lead is connected with the aluminum column, the other end of the lead is connected with the upper end and the lower end of the piezoelectric anti-seismic structure respectively, the upper side and the lower side of the aluminum column are tightly connected with thin-wall steel pipes respectively, and micro-expansion cement paste is poured into the thin-wall steel pipes. Structural damping is effectively increased, the anti-seismic performance of the structure is enhanced, the structure is not damaged in small earthquakes through elasticity of the aluminum columns, active control over structural seismic resistance is achieved through the inverse piezoelectric effect of piezoelectric materials, and therefore buildings can be repaired in medium earthquakes and do not fall in large earthquakes.
本发明公开了一种使用压电材料的抗震耗能柱，包括铝柱，所述铝柱内套设有压电抗震结构，所述压电抗震结构包括电源和若干第一压电圆环，相邻所述第一压电圆环之间穿插有第二压电圆环，所述电源的正负极分别连接有导线，所述导线的另一端分别连接所述压电抗震结构的上下两端，所述铝柱的上下两侧分别紧密连接有薄壁钢管，所述薄壁钢管内灌注有微膨胀水泥浆，本发明设置有铝柱和压电抗震结构，通过压电材料的逆压电效应与铝柱的弹性，有效增大结构阻尼，加强结构抗震性能，通过铝柱的弹性实现小震不坏，通过压电材料的逆压电效应实现了结构抗震的主动控制，从而实现建筑物的中震可修、大震不倒。
