The utility model relates to a static load test rack for a simply supported prestressed concrete channel beam. The static load test rack comprises a main beam, wherein the main beam extends longitudinally, the top surface of the main beam is provided with three cross beams and two upper end beams, the upper cross beams and the upper end beams all extend transversely, the three cross beams are uniformly distributed along the longitudinal direction in a manner of taking the midspan of the main beam as reference, and the two upper end beams are arranged on the two end parts in longitudinal direction of the main beam; the bottom surface of the main beam is provided with three lower cross beams, the three lower cross beams are arranged in the longitudinal middle part and the two ends of the main beams respectively, and the lower cross beams extend transversely. By the structure, the mode of force bearing of two main beams is changed into the mode of force bearing of the single main beam, the main beam deviates from a transverse center line, and the cross beams transmit load, and thus, the effect of sharing the static load test rack in both transverse direction and longitudinal direction is realized; and moreover, the static load test rack is simple in structure and convenient to operate.
