Safety protection device for building construction

The invention relates to the technical field of building construction protection, in particular to a safety protection device for building construction, which comprises a stand column, clamping pieces are distributed around the stand column, handrails are clamped in the clamping pieces, water blocking plates are detachably connected to the bottoms of the handrails and on one side of the stand column, and water permeable holes distributed at equal intervals are formed in the water blocking plates. A water storage tank is installed at the bottom of the water blocking plate, a water pipe is arranged above the water storage tank, the two ends of the water pipe are in threaded connection with sleeves, a water pumping structure is connected between the water storage tank and the water pipe, and a flow dividing structure is arranged in the stand column. In rainy days, accumulated water enters the water storage tank after penetrating through the water permeable holes of the water blocking plate, the water pumping str
