description The utility model provides a novelcoupling piece for T-steel retractable tunnel supporting frame. The utility model is characterized in that the transverse cross-section of a slipping member (3) is in oblique I-shaped, a lap joint stands out a plurality of ear benches (7) with screw (8), the ear bench (7) and a poles leg (1) are connected into one integration by bolts (2). The bending resistant modulus of the slipping member (3) can be enlarged by means of adopting this framework. The utility model has the advantages of high strength, easy assembly and disassembly, so the situation of stress more tends towards reasonable. A clamp-on friction block (5) is provided with a spacing groove (9), and the slipping member (3) is arranged in slot, so a poles leg (1) is prevented toppling toward axial direction of a tunnel, and it is convenient and rapid to loading and unloading the prop.
