About this detail

Structural reinforcement for openings ranging from 6 inches to 36 inches wide in concrete slabs over metal deck. Reinforcing angles of size L1-1/2x1-1/2x3/16 are specified where width is 12 to 18 inches, and L2x2x1/4 where width exceeds 18 up to 36 inches, to be installed prior to cutting the hole. #4 trim bars are provided around the perimeter with typical slab reinforcement positioned above the angle, allowing bars to be bent down to within 3/4 inch clearance from the deck or pass through maximum 5/8 inch diameter holes in the angle legs. Angles are omitted at single openings less than 12 inches or where a structural beam occurs above the deck.
