The individual limiting plate；It is connected with each other between two telescopic connection units by connector；Set on the connector
There is the connecting hole for being connected with the longitudinally connected muscle.
In a kind of preferred embodiment of the present utility model, the limiting plate is L-shaped angle steel limiting plate；The L-shaped angle
Steel limiting plate includes orthogonal connecting portion and limiting section；Axis of the connecting portion along the telescopic connection unit
Welded with the telescopic connection unit in direction；The axis of the limiting section and the telescopic connection unit mutually hangs down
Directly.
In a kind of preferred embodiment of the present utility model, the connector is by two adapter sleeves being arranged parallel to
With a connecting rod composition；The two ends of the connecting rod have been respectively and fixedly connected with the adapter sleeve, the central axis of the connecting rod with
The central axis of the connecting hole is mutually perpendicular to；It is provided with the adapter sleeve for being slidably matched company with the longitudinally connected muscle
The connecting hole connect.
The beneficial effects of the utility model are：The utility model is simple in construction, easy to install, even if steelframe is being installed
When in the presence of certain error in the case of also can guarantee that the stabilization between steelframe is quickly connected, so as to eliminate welding, it is to avoid
Speed of application caused by welding is slow, pollute, quality is difficult to ensure the relevant issues such as card；Simultaneously by setting scalable unit to connect longitudinal direction
Connect and fix, improve installation rate, correction is flexible, it is ensured that install what is connected in the range of tolerance in steelframe
Adjustability.
