About this detail

This structural detail shows reinforcement configurations for openings cut through Formlok steel decking above supporting beams. Angle profiles measuring 1-3/4 inches by 1-3/4 inches by 1/4 inch or steel tubes measuring 1-1/2 inches by 3 inches by 1/8 inch are placed on top of the deck adjacent to cut webs. Additional reinforcing bars are positioned at the corners of larger rectangular openings above the steel tubes. The angles or tubes must extend three webs past the deck opening on typical installations.
