The invention discloses a straddle type monorail traffic track beam bearing and pulling supporting seat which comprises upper anchoring units, a beam body supporting frame, pressure bearing supporting seats, bearing and pulling portal frames, a pre-embedded steel plate and lower anchoring units. The upper anchoring units are arranged on the top of the beam body supporting frame; the lower anchoring units are arranged at the bottom of the pre-embedded steel plate; the beam body supporting frame is arranged on the pre-embedded steel plate through the two pressure bearing supporting seats arranged at the bottom of the beam body supporting frame; the two pressure bearing supporting seats have the vertical and transverse load bearing function, the rotation and adjustment function, the longitudinal sliding function and the mounting and adjustment function; the two bearing and pulling portal frames are arranged on the pre-embedded steel plate and located on the two sides of the beam body supporting frame; and convex lugs on the two sides of the beam body supporting frame are connected with the bearing and pulling portal frames correspondingly by rotating sliding friction pairs. The structure is simple, the design is reasonable, stress bearing performance is excellent, good safety, environmental adaptability and economic efficiency are achieved, and the straddle type monorail traffic track beam bearing and pulling supporting seat can bear loads of pulling, pressing, bending, shearing, torsion and the like which are transmitted by a beam body under special working conditions and reliably transmit the loads to a lower structure.
