Multidirectional displacement combing tooth type telescopic seam
A multidirectional displacement combing tooth type telescopic seam comprises a combing tooth type plate capable of moving in the longitudinal direction as a whole, an anchor bar fixedly connected with a bridge beam body, and displacement boxes arranged between the combing tooth type plate and the anchor bar. At least one groove is formed in the end, away form combining teeth, of the combing tooth type plate. Circular through holes are formed in the bottoms of the grooves. Transverse kidney-shaped grooves corresponding to the grooves are formed in the lower portion of displacement box upper cover plates. Transverse kidney-shaped holes attached to the circular through holes are formed in the displacement box upper cover plates. The combing tooth type plate can transversely move in the waist direction through connection parts penetrating through the circular through holes and the transverse kidney-shaped through holes. Arc-shaped face gaskets which can make the combing tooth type plate rotate in the longitudinal direction are arranged at the positions, located in the transverse kidney-shaped grooves and attached to the transverse kidney-shaped through holes, of the connection parts. By means of the multidirectional displacement combing tooth type telescopic seam, when transverse staggered displacement happens to the bridge beam body, the combing tooth plate can make the connection parts correspondingly and transversely move and make the arc-shaped face gaskets longitudinally rotate through the connection parts which can transversely move, and the anti-displacement capacity of a bridge is comprehensively improved.
