Dovetail groove type transverse large-displacement bridge finger-shaped telescopic device
The invention discloses a dovetail groove type transverse large-displacement bridge finger-shaped telescopic device, and particularly relates to the field of road and bridge construction. The dovetailgroove type transverse large-displacement bridge finger-shaped telescopic device comprises a left bridge beam body and a right bridge beam body, and a bridge expansion joint is arranged between the left bridge beam body and the right bridge beam body; reserved mounting notches are formed in the tops of the sides, close to each other, of the left bridge beam body and the right bridge beam body correspondingly, finger-shaped seams are formed in the reserved mounting notches, and the finger-shaped seams are of a seam crossing type structure. A dovetail groove is formed in a main steel plate, a trapezoidal sliding block is fixed to a comb plate through a fastening bolt, the trapezoidal sliding block and the dovetail groove are matched to form a transverse displacement control unit, and the main steel plate and the comb plate relatively move through the transverse displacement control unit, so that the finger-shaped telescopic device achieves large transverse displacement; and the depth ofthe reserved mounting notches of the telescopic device of a bridge or a building does not need to be increased, and application and popularization are facilitated.
本发明公开了一种燕尾槽式横向大位移量桥梁指形伸缩装置，具体涉及路桥建设领域，包括左桥梁梁体和右桥梁梁体，所述左桥梁梁体和右桥梁梁体之间为桥梁伸缩缝，所述左桥梁梁体和右桥梁梁体相互靠近的一侧顶部均开设有预留安装槽口，所述预留安装槽口内设置有指形缝，且所述指形缝采用跨缝式结构。本发明通过在主钢板上开设燕尾槽，梳齿板通过紧固螺栓固定梯形滑块，梯形滑块与燕尾槽配合形成横向位移控制单元，主钢板与梳齿板通过横向位移控制单元产生相对移动，从而使指形伸缩装置实现大的横向位移，且不需要加深桥梁或建筑物的伸缩装置预留安装槽口的深度，有利于推广使用。
