Three-way limiting anti-seismic device for bridge and application thereof
The invention relates to a bridge anti-seismic device and application thereof, in particular to a three-way limiting anti-seismic device for a bridge and application of the three-way limiting anti-seismic device. The three-way limiting anti-seismic device for the bridge comprises an abutment and a beam body erected on the abutment through a support. The lower portion of the steel bar is anchored to an abutment, a gap is formed between the upper end of the steel bar and a first steel pipe longitudinally embedded in the beam body, the lower end of the connecting cable is fixed to the upper end of the steel bar, a loose section is arranged in the middle of the connecting cable, the deformation quantity of the loose section is matched with the vertical design stroke of the beam body, and the upper end of the connecting cable is anchored in the beam body on the outer side of the first steel pipe. The problem that in the prior art, multi-direction limiting cannot be achieved or components are densely arranged is solved. The method has the advantages of wide application range, flexible arrangement, convenient construction and the like.
本发明涉及桥梁抗震装置及其应用，尤其涉及一种桥梁用三向限位抗震装置及其应用。桥梁用三向限位抗震装置包括墩台，通过支座架设于墩台上的梁体；钢棒下部与墩台锚固，钢棒上端与梁体内纵向预埋的第一钢管之间设有间隙，连接索的下端与钢棒上端固定，连接索的中部设有松弛段，该松弛段的形变量与梁体竖向设计行程适配，连接索的上端锚固于第一钢管外侧的梁体内。本发明解决了现有技术存在的无法实现多向限位或构件设置密集等问题。具有适用范围广、设置灵活、施工便捷等优点。
