Rotating shaft type three-dimensional adaptive large-displacement expansion joint
The invention relates to the technical field of expansion joints, and discloses a rotating shaft type three-dimensional adaptive large-displacement expansion joint which comprises a main toothed plate, a toothed plate seat, an auxiliary toothed plate and a fastening assembly, an elastic rubber body is arranged between the main toothed plate and the toothed plate seat, the fastening assembly comprises a bolt, a spring and a nut, the bolt sequentially penetrates through the main toothed plate, the elastic rubber body and the toothed plate seat, and the elastic rubber body is arranged on the elastic rubber body. The head of the bolt is located in a counter bore in the main toothed plate, the lower end of the bolt is sleeved with the spring, the nut is in threaded connection with the lower end of the bolt, and the two ends of the spring abut against the toothed plate base and the nut respectively. The main comb teeth of the main toothed plate and the auxiliary comb teeth of the auxiliary toothed plate are arranged at intervals in a crossed manner; the rotating shaft type three-dimensional adaptive large-displacement expansion joint solves the problems that an existing expansion joint cannot completely adapt to bridge deformation, bolts are prone to loosening, and certain noise pollution is caused due to the fact that bridge deck live loads have large impact on the expansion joint.
本发明涉及伸缩缝技术领域，公开了一种转轴式三维适应大位移伸缩缝，包括主齿板、齿板座、副齿板和紧固组件，所述主齿板与齿板座之间设有弹性橡胶体，所述紧固组件包括螺栓、弹簧和螺母，所述螺栓依次穿过主齿板、弹性橡胶体和齿板座，所述螺栓的头部位于主齿板上的沉孔内，所述弹簧套设在螺栓的下端，所述螺母与螺栓的下端螺纹连接，所述弹簧的两端分别与齿板座和螺母抵接；所述主齿板的主梳齿和副齿板的副梳齿交叉间隔设置；本发明提供的一种转轴式三维适应大位移伸缩缝，解决了现有伸缩缝不能完全适应桥梁变形、螺栓易松动以及桥面活载对伸缩缝冲击大且造成一定噪声污染的问题。
