After the concrete is poured, when the opening is not needed, temporary opening protection needs to be built to prevent construction workers from falling and causing installation hazards. At present, temporary opening protection generally uses a square wood that matches the size of the opening to be nailed to the bottom of a wooden formwork that is larger than the opening, and the wooden formwork is covered on the opening. At the same time, the square wood is stuck in the opening to prevent the wooden formwork from shifting.
