摘要
The friction lock in closed format with blocking cutting for mining and tunnel construction comprises rolled channel profiles (1,2) with tension convolutions and hollow grooves. With tension screws (10), the channel profiles are clamped via a profile-engaging, radial upper tab (6,7) with an integrated rib and a lower tab (8,9), which supports in the hollow grooves of the lower channel profile (1). The blocking devices are formed by blocking cutters (5) provided on the lower tab (9) of the friction lock (11,12) or on the upper tab (7) and the stop lock (14).
