FIELD: building, particularly scaffold systems or three-dimensional rod frames.
SUBSTANCE: lock comprises horizontal tubular member with fixing members arranged at ends thereof. Spaced rod members of three-dimensional structure are installed on fixing members. One fixing member located at one tubular member end is formed as U-shaped clamp to be laid on horizontal rod member of three-dimensional structure. Clamp axis along slot extends transversely to longitudinal tubular member axis. One fixing member created on another tubular member end is L-shaped and has shoulder axes arranged in vertical plane and free shoulder directed downwards. Another fixing member is C-shaped and extends in horizontal plane. Bent part of above member is directed away from tubular member. Length of U-shaped clamp along slot is less than distance between horizontal shoulder of L-shaped member and C-shaped member.
EFFECT: increased reliability of structure member fixation.
