Setting pressure device for support of U-shaped steel course

The utility model relates to a setting pressure device for the support of a U-shaped steel course. The setting pressure device comprises an upper setting pressure clipping cable and a lower setting pressure clipping cable which are arranged on the U-shaped steel beam and positioned in the fore and aft positions of a fixed clipping cable at the juncture, and a hydraulic jack connected between the upper setting pressure clipping cable and the lower setting pressure clipping cable. The hydraulic jack is charged with liquid and then drives an arched beam to move upward, the arched beam generates asetting pressure to the course guard plate, and the setting pressure forms a semicircular carrier ring to the surrounding rock of the top plate of the course along the beam of the support, so as to play a function of active support to the surrounding rock of the arched course, thereby enhancing the overall strength, the completeness and the stability of the jointed coal rock, effectively improving the stress state of the
