About this detail

Structural support framing for elevator guide rails anchors to concrete slabs and steel framing. Hollow structural section posts are positioned per plan centered on the elevator rail, with post sizes specified in the rail support table using members such as HSS12x4x3/8 and HSS10x4x3/8. At the slab edge, an ASTM A36 embed plate measuring 1/2 inch by 7 inches with a length equal to the hollow structural section plus 4 inches is anchored with two 1/2-inch diameter by 4-inch studs at 12 inches on center and three number 4 reinforcing bars at 8 inches on center. The hollow structural section post connects via an L7x4x1/2 by 0-foot-6-inch angle with two 3/4-inch diameter ASTM A307 bolts at 3 inches, featuring a vertical slotted hole through the hollow structural section and a full-height 3/8-inch stiffener plate at the centerline of each post. At the top support condition, an embed plate 1/2 inch by 8 inches with four 1/2-inch diameter by 4-inch studs at 6 inches on center secures an L6x6x1/2 angle with two 3/4-inch diameter ASTM A307 bolts through a vertical slotted hole. Double post and spreader beam conditions use 3/8-inch and 1/4-inch plates each side with 3/4-inch diameter ASTM A307 bolts and 5/16-inch or 3/16-inch fillet welds as indicated. Contractor shall coordinate locations with approved elevator supplier drawings and support rails off concrete walls where possible.
