Bridge multidirectional limiting device
The invention discloses a bridge multidirectional limiting device. The device comprises a main beam arranged on an abutment, fixing anchor plates are fixedly arranged on the bottom side of the main beam and the side wall of the abutment, cable chains are fixedly arranged at the tail ends of the fixing anchor plates, and the other ends of the cable chains are arranged in telescopic boxes between the cable chains. A limiting steel plate fixed to the end of the cable chain is arranged in the telescopic box in a sliding mode, and a limiting spring is arranged between the limiting steel plate and the telescopic box. The invention aims to provide the bridge limiting device to meet the requirements of normal use of a bridge and displacement under the action of an earthquake so as to achieve a multi-directional limiting function between pier beams of the bridge under the action of the earthquake and thoroughly overcome the one-way limiting defect of the conventional bridge limiting device.
本发明公开了一种桥梁多向限位装置，包括设置在墩台上的主梁，所述主梁的底侧与墩台的侧壁均固定设置有固定锚板，固定锚板的末端均固定设置有索链，索链的另一端均设置在索链之间的伸缩盒内；所述伸缩盒内滑动设置有固定在索链端部的限位钢板，限位钢板与伸缩盒之间设置有限位弹簧。本发明旨在提供一种桥梁限位装置来满足桥梁正常使用及地震作用下的位移需求，以达到地震作用时桥梁的墩梁间的多向限位功能，彻底改善以往桥梁限位装置的单向限位缺陷。
