Further, the connecting plate adopts forging and pressing or cast molding's mode integrated into one piece, the connecting plate includes backplate, roof, bottom plate and riser, the backplate is the arc and welds with the sleeve inner wall, the screw hole sets up on the roof, the one end and the riser of roof, bottom plate are connected perpendicularly, the backplate is connected with the rear side of roof, bottom plate, the preceding side of roof, bottom plate is sunken to the backplate, and the radian of its depressed part is unanimous with the sleeve.

Furthermore, the outer wall of the sleeve is connected with six lifting lugs, wherein four lifting lugs are arranged on the outer wall of the sleeve at equal intervals and close to the bottom plate, and the other two lifting lugs are arranged on the upper portion of the outer wall of the sleeve.

The utility model has the advantages that:

1. The mode of C type structure is adopted to the connecting plate, lays jacking anchor clamps when middle C type open-ended space is used for the construction jacking, provides effective quick construction scheme to improve the progress of urban rail transit construction in earlier stage.

2. The steel spring floating slab track bed is short in skylight time, and when the operation was maintained, the maintenance process was checked efficiently again, and the supplementary frock clamp that needs is many and loaded down with trivial details, and this novel isolator cancels complicated maintenance frock, and simple and fast carries out the maintenance of circuit in the skylight time.

3. The connecting plate adopts forging and pressing or cast molding's mode integrated into one piece, guarantees the uniformity of product, has both guaranteed C type open-ended optimized structure, increases C type open-ended structural strength simultaneously.

4. by adopting a simplified design and manufacturing process, the weight of the product is reduced on the premise of not reducing the performance and the quality of the product, and a great deal of convenience is brought to construction.
