Safety protection support for constructional engineering

The utility model discloses a safety protection support for constructional engineering, which belongs to the technical field of constructional engineering and comprises four vertical rods, connecting pieces are clamped at the top ends and the bottom ends of the vertical rods, and four cross rods are clamped between the two vertical rods on the left side and the two vertical rods on the right side through the four connecting pieces. According to the safety protection support for constructional engineering, by arranging the mounting box, the vertical plates, the mounting plates, the clamping grooves, the lead screws, the lead screw nuts, the clamping plates and the limiting grooves, the vertical plates in the safety protection support are cooperatively mounted on the outer surfaces of the corresponding vertical rods in a clamping mode, the mounting stability of the safety protection support can be effectively guaranteed, and the use strength can be guaranteed; and meanwhile, quick disassembly and assembly can b
