About this detail

The new elevator shaft connects to structural framing using hollow structural section supports, a hoist beam support post, and an L6x4x3/8-inch angle measuring four feet three inches long secured with six 3/4-inch by 4-inch lag screws, with two lag screws per block. Framing incorporates three bays with two rows of 4x wood blocking featuring L90 angles at each end typically, alongside two 3/4-inch machine bolts centered in long oval holes with a maximum spacing of eighteen inches. Continuous CMSTC14 and MSTC40 straps tie the assembly together, supported by plywood sheathing sized per plan and a bond beam located above as indicated. An existing attic level floor intersects with the shaft wall assembly, referencing additional support details for roof trusses.
