Noise-reduction self-cleaning bridge expansion device and mounting method
The invention relates to the field of bridge expansion joints, in particular to a noise-reduction self-cleaning bridge expansion device and a mounting method. The telescopic device comprises a fixed edge beam (7) and a sliding edge beam (4) which are obtained by cutting pi-shaped steel. The fixed edge beam (7) and the sliding edge beam (4) respectively comprise teeth which are formed by cutting pi-shaped steel and are staggered with each other; a fixed plate (6) is fixed on the fixed boundary beam (7) through a step surface; a sliding plate (5) is fixed on the sliding boundary beam (4) through a step surface; the fixed plate (6) and the sliding plate (5) are arranged up and down and can slide relatively; an inclined plane is arranged above the fixed edge beam (7) and is a flow guide slope; when a concrete anti-cracking anchoring plate (10) is adopted, a concrete anti-cracking steel plate (20) is welded to the position, flush with a bridge floor, above the anti-cracking anchoring plate, and the concrete anti-cracking steel plate (20) is of a latticed structure. The structure can protect the post-cast strip concrete from cracking, enhance durability and reduce maintenance frequency.
本发明涉及桥梁伸缩缝领域，尤其涉及一种降噪自清理桥梁伸缩装置及安装方法。该伸缩装置包含通过切割π型钢得到的固定边梁（7）和滑动边梁（4）；固定边梁（7）和滑动边梁（4）二者各自包含由π型钢切割而成的相互交错的齿;固定边梁（7）上通过台阶面固定有固定板（6）；滑动边梁（4）上通过台阶面固定有滑动板（5）；固定板（6）和滑动板（5）上下布置且能够相对滑动；固定边梁（7）上方包含倾斜面，该倾斜面为导流坡；当采用混凝土防裂锚固板（10）时，在防裂锚固板上方与桥面齐平位置焊接有混凝土防裂钢板（20），混凝土防裂钢板（20）为网格状结构;上述结构可以保护后浇带混凝土防止其开裂，增强耐久性，降低维修养护频率。
