About this detail

An existing concrete pan joist slab with a one-inch cementitious topping supports equipment through a suspended one and five-eighths inch by twelve-gauge channel strut installed snug-fit open-face up between existing concrete pan joists. An L4x3x1/4 angle with long legs horizontal is secured to the concrete joist with a half-inch diameter expansion anchor having a two-inch embedment, utilizing a beveled washer between the angle and the bottom of the concrete slab for full bearing. An anchor bolt passes through the concrete topping and structural slab to anchor into the channel strut below, equipped with a standard washer plate at the channel strut. An alternate half-inch diameter expansion anchor with a two-inch embedment fastens directly into the concrete slab where the anchor aligns with the concrete joist.
