FIELD: construction.
SUBSTANCE: at least one actuator and at least one transfer rod are installed in at least one slot of a frame and are fixed to each other by means of a screw. The screw is engaged with a through hole formed in a transfer rod. The through hole is formed in a transfer rod after installation of the actuator and the transfer rod in the slot. The hole is made by means of the screw top as a result of its screwing into the threaded hole made in the connection part of the actuator. The transfer rod comprises a central part and two side parts forming appropriate channel-shaped guides arranged at opposite sides relative to the central part. The central part has two side ledges having inclined lower surfaces. The actuator has a base and two parallel longitudinal ribs that protrude from the base. According ends of the longitudinal ribs have the shape that ensures sliding connection with the guides in longitudinal direction. Ends of longitudinal ribs have appropriate internal side ledges having inclined upper surfaces that contact with the inclined lower surfaces, when the screw is tightened to form a hole.
EFFECT: increased accuracy of installation and makes it possible to eliminate stages of measurement, cutting and drilling of rods.
