Multidirectional telescoping device and bridge of shifting

The utility model relates to a telescoping device for building provides the multidirectional telescoping device that shifts, including striding seam roof beam and at least one fishback subassembly, still including two elasticity plate rubber support that arrange the structural joint both sides respectively in, the at least one side of striding the seam roof beam has all set gradually at least one fishback subassembly along the direction of keeping away from structural joint, and seam roof beam and each fishback subassembly are striden in two elasticity plate rubber support supportings, still provide a bridge, including above -mentioned telescoping device. The utility model discloses the fishback subassembly of telescoping device then can be eliminated and span flexible change that the structural joint direction produced and influence that the perpendicular to spanes the horizontal corner of direction, and elasticity plate rubber support can be through uniform compression not in the horizontal plane, adapt to
