The invention relates to a safety shaking frame for constructional engineering. The safety shaking frame comprises a support frame and a revolving drum. The revolving drum is connected with a driving mechanism. A safety rope and a safety hook are arranged on the revolving drum. First gears are arranged at two ends of the revolving drum. A transmission shaft is arranged on the lower side of the revolving drum. Second gears are arranged at two ends of the transmission shaft. Each first gear is connected with the corresponding second gear via a chain. A worm gear is arranged in the middle of the transmission shaft. A worm is arranged on the lower side of the worm gear. A revolving handle is arranged at one end of the worm. A lug is arranged at the other end of the worm. A non-return pin is arranged on the lateral side of the lug and mounted on the upper side of a support table of a mounting seat, and one end of the non-return pin is connected with a third hinge of the mounting set. The safety shaking frame for constructional engineering has the advantages that according to the technical scheme, the non-return pin cooperates with the lug, the worm is prevented from revolving clockwise, falling of a mud bucket is prevented, and safety accidents are avoided.
