Noise reduction tenon-and-mortise type bridge comb plate expansion joint device and installation method
The invention relates to the field of bridge engineering, and provides a noise reduction tenon-and-mortise type bridge comb plate expansion joint device and a mounting method.The noise reduction tenon-and-mortise type bridge comb plate expansion joint device comprises a first fixing block and a second fixing block, the first fixing block is provided with a tenon-and-mortise assembly, the tenon-and-mortise assembly comprises a reserved groove, a tenon and a mortise, the tenon is mounted in the mortise, and the tenon is mounted in the reserved groove; the preformed groove is formed between the mortises, the tenon and the preformed groove form a movable space, and a rotating shaft is arranged in the preformed groove; the comb tooth plate assembly comprises a first comb tooth plate and a second comb tooth plate which are in butt joint with each other, the second comb tooth plate is connected with the second fixing block, and the rotating shaft is arranged at the end, away from the comb teeth, of the first comb tooth plate and fixedly connected with the first comb tooth plate; the rotating shaft rotates in the reserved groove to drive the first comb plate to deform between the mortise and the tenon in the vertical direction relative to the second comb plate. Bolts are replaced with the tenon-and-mortise assemblies, fatigue fracture of the bolts is avoided, the service life of the bridge body is prolonged, and reliability is improved.
本发明涉及桥梁工程领域，提供一种降噪榫卯型桥梁梳齿板伸缩缝装置和安装方法，降噪榫卯型桥梁梳齿板伸缩缝装置包括第一固定块和第二固定块，第一固定块上设置有榫卯组件，榫卯组件包括预留槽、榫头和榫槽，榫头安装在榫槽中，预留槽设置在榫槽之间，榫头与预留槽形成一活动空间，预留槽中设置有转轴；梳齿板组件，梳齿板组件包括相互对接的第一梳齿板和第二梳齿板，第二梳齿板与第二固定块连接，转轴设置在第一梳齿板远离梳齿的一端，与第一梳齿板固定连接，转轴在预留槽中转动带动第一梳齿板相对于第二梳齿板在榫槽和榫头之间沿竖直方向变形。本发明使用榫卯组件代替螺栓，避免螺栓疲劳断裂，延长桥梁本体的使用寿命，提高可靠性。
