Two-way limiting shape memory alloy energy dissipation type bridge anti-seismic stop block
The invention relates to a two-way limiting shape memory alloy energy dissipation type bridge anti-seismic stop block which is arranged between a cover beam and a main beam of a bridge and comprises a shell which comprises an upper top plate fixed to the lower surface of the main beam and a sleeve installed below the upper top plate; the base comprises a lower bottom plate fixed to the cover beam and an enclosure arranged in the middle of the lower bottom plate. The shape memory alloy energy dissipation elements are arranged on the surfaces of all the side walls in the sleeve; the bottom end of the body is clamped into the enclosure, the top end of the body extends into the sleeve, and a gap is reserved between the top end of the body and the shape memory alloy energy dissipation element. Compared with the prior art, huge collision energy of the upper beam body to the check block can be effectively dissipated, and displacement of the upper beam body in the transverse bridge direction and the longitudinal bridge direction can be well limited.
本发明涉及一种双向限位形状记忆合金耗能型桥梁抗震挡块，布置在桥梁的盖梁与主梁之间，该抗震挡块包括：外壳，其包括与所述主梁下表面固定的上顶板、安装在所述上顶板下方的套筒；底座，其包括与所述盖梁固定的下底板、以及设置在所述下底板中间位置的围护；布置在所述套筒内各个侧壁表面的若干形状记忆合金耗能元件；以及本体，其底端卡入所述围护中，顶端则伸入所述套筒内并与所述形状记忆合金耗能元件之间留有空隙。与现有技术相比，本发明不仅能有效地耗散掉上部梁体对挡块的巨大碰撞能量，还能很好地限制上部梁体在横桥向和顺桥向两个方向的位移。
