Expansion joint unit component and bridge telescopic device
The invention discloses an expansion joint unit component and a bridge telescopic device. A plurality of hollow accommodating cavities are formed in a box-type telescopic table, a plurality of comb tooth telescopic arms are arranged on one side of a top surface of the box type telescopic table in an outward extending manner, a groove is formed between every two adjacent comb tooth telescopic arms,one side of a bottom surface of the box type telescopic table extends outwards to be provided with a plurality of front edge protruding blocks, the front edge protruding blocks are located below thecomb tooth telescopic arm, a plurality of rectangular embedded rib connecting frames are arranged on a side, deviating from the comb tooth telescopic arm, of the box type telescopic table, fixing lugplates are arranged on vertical surfaces of the two ends, parallel to the extending direction of the comb tooth telescopic arm, of the box type telescopic table, and a plurality of bolt penetrating holes are formed in the fixing lug plates. The box-type telescopic table is advantaged in that the box-type telescopic table is of a hollowed-out structure, and material consumption is reduced; horizontal displacement of a bridge structure can be met, vertical displacement of the bridge can further be met, stable vehicle passing is ensured, the impact force generated by vehicle running is eliminated, the service life of the bridge is effectively prolonged, material consumption is reduced, and construction cost is reduced.
本发明公开了一种伸缩缝单元构件及桥梁伸缩装置，箱式伸缩台内部设置有多个中空的容纳腔，箱式伸缩台的顶面一侧向外延伸设置有多个梳齿伸缩臂，相邻梳齿伸缩臂之间形成有凹槽，箱式伸缩台的底面一侧向外延伸设置有多个襟边凸块，襟边凸块位于梳齿伸缩臂的下方，箱式伸缩台背离梳齿伸缩臂的一侧设置有多个矩形预埋筋连接框，箱式伸缩台与梳齿伸缩臂延伸方向相互平行的两端竖直面处设置有固定耳板，固定耳板上开设有多个螺栓穿孔。效果：箱式伸缩台采用镂空结构，减少了材料用量；满足桥梁结构的水平位移，还可满足满足桥梁竖向位移，确保车辆通行平稳，消除车辆行驶产生的冲击力，有效延长桥梁的使用寿命，降低了材料用量，降低了建造成本。
