Grading yield energy dissipation metal damper considering temperature effect and suitable for bridge
The invention relates to a graded yield energy dissipation metal damper considering the temperature effect and suitable for a bridge, the lower ends of two U-shaped bent plates between an upper connecting plate and a lower connecting plate are welded and fixedly installed at the two ends of the lower connecting plate correspondingly, sliding grooves are fixedly formed in the upper ends of the two U-shaped bent plates correspondingly, and sliding blocks are slidably connected into the sliding grooves correspondingly; the upper ends of the sliding blocks are fixedly welded to the two ends of the upper connecting plate correspondingly. U-shaped plate tooth blocks are welded and fixed to the ends of the opposite sides of the upper ends of the U-shaped bent plates, corrugated steel plates are welded and fixed to the lower connecting plates, cover plates are welded and fixed to the corrugated steel plates, cover plate tooth blocks are welded and fixed to the two ends of each cover plate, the cover plate tooth blocks are meshed with teeth on the U-shaped plate tooth blocks, and gaps are reserved between the cover plate tooth blocks and the U-shaped plate tooth blocks; the problems that the deformation rigidity of a second stage of an existing graded yield energy dissipation metal damper is generally smaller than that of a first stage, large deformation and damage are likely to be generated when the metal damper suffers from a large earthquake, and the repair difficulty after the earthquake is large are solved.
本发明涉及一种考虑温度效应适用于桥梁的分级屈服耗能金属阻尼器，上连接板、下连接板之间两块U型弯曲板的下端分别焊接固定安装在下连接板的两端，两块U型弯曲板的上端分别固定安装有滑槽，滑槽内均滑动连接有滑块，滑块上端分别焊接固定安装在上连接板的两端；U型弯曲板上端相对一侧的端部焊接固定有U型板齿块，下连接板上焊接固定有波纹钢板，波纹钢板上焊接固定有盖板，盖板两端焊接固定有盖板齿块，盖板齿块与U型板齿块上的齿相啮合且相互之间留有间隙；解决现有分级屈服耗能的金属阻尼器一般第二阶段的变形刚度小于第一阶段变形刚度，在遭受大震时容易产生较大的变形和损伤，震后修复难度较大的问题。
