Further, the junction steel plate of two neighboring steelframe unit end is respectively positioned in sleeve.
Further, the sleeve includes front end, follower head and stack shell, and the front end and follower head pass through stack shell phase
Connection；The front end of sleeve is connect with one of steelframe unit activity, another steelframe element solder of the follower head of sleeve.
Further, the outer edge of the junction steel plate extends to the inner wall of the stack shell of sleeve.
Further, the sleeve is fixed on country rock by anchor pole.
Further, the steelframe unit is made of I-steel.
The beneficial effects of the utility model are：The utility model is shortened big to adapt to tunnel by flexible connector compression
Deformation, its elasticity modulus is easily controllable when flexible connector is processed, and the external force of triggering flexible connector compressive deformation is big for tunnel
Deformation, eliminates the influence of the extraneous factor in addition to serious deformation；And by being sleeved on outside two neighboring steelframe unit
Sleeve not only plays a protective role to flexible connector, and concrete etc. is avoided to be mixed into the gap of flexible connector, influences elasticity
The compressive deformation of connector also limits two neighboring steelframe unit, and the center centering for making two neighboring steelframe unit is inclined
Difference is in allowed band；Finally, can support action effectively be played to country rock in the case of serious deformation, improves country rock oneself
Ability to bear.
