Bridge noise reduction and seismic resistance method
The invention discloses a bridge noise reduction and seismic resistance method. A multidirectional displacement comb plate type telescopic device composed of unit structures is used, each unit structure comprises a fixed tooth plate and a movable tooth plate, and when a bridge structure moves longitudinally, a pressing connection mechanism and a sliding box are arranged on the front portion of each movable tooth plate; the requirement for longitudinal displacement of the telescopic device is met, meanwhile, the stress state of a movable plate tooth end is improved, a lever structure is avoided, and a fixed end bolt stress is reduced; and when transverse displacement or rotation occurs, a special anchoring device and a transverse displacement assembly are arranged on the rear portion of themovable tooth plate, and the requirements for transverse displacement and rotation are met through elasticity and transverse gaps of the pressing blocks.
本发明公开了一种桥梁降噪抗震方法，使用由单元式结构组成的多向变位梳齿板式伸缩装置，每个单元结构包括固定齿板和活动齿板两部分，桥梁结构发生纵向位移时，活动齿板前部设置压紧连接机构和滑移箱，实现伸缩装置纵向位移的要求同时改善活动板齿端受力状态，避免形成杠杆结构，减轻固定端螺栓受力；发生横向位移或转动时，活动齿板后部设置专用锚固装置与横向位移组件，利用压紧块的弹性和横向间隙实现横向位移和转动要求。
