description The utility model discloses a building construction guardrail which comprises a bottom plate, the two sides of the bottom plate are both communicated with supporting plates, the front side and the rear side of the top of the bottom plate are both fixedly connected with guardrail plates, the interior of the bottom plate is fixedly connected with a double-shaft motor, and the output end of the double-shaft motor is fixedly connected with a transmission rod. The end, away from the double-shaft motor, of the transmission rod is fixedly connected with first helical teeth which are located in the supporting plate. The output end of the double-shaft motor drives the transmission rod and the first helical tooth to rotate, the first helical tooth drives the second helical tooth and the screw rod to rotate, the screw rod pushes the threaded sleeve and the connecting plate to move upwards, the connecting plate drives the lifting guardrail to move upwards, the protection height of the guardrail plate is increased, after
