Abstract: An assembly comprising a first precast concrete structure including a first rebar member and a second precast concrete structure including a second rebar member. The second rebar member is aligned with the first rebar member along an axis. The assembly further includes a sleeve with an aperture. The sleeve is coupled to the first rebar member. The assembly further includes a connecting member coupled to the second rebar member, and a rebar dowel coupled to the connecting member; wherein the rebar dowel extends through the aperture in the sleeve and is at least partially received within the sleeve. The assembly further includes a grout positioned within the sleeve; a gasket positioned between the sleeve and the connecting member; a seal positioned between the first precast concrete structure and the second precast concrete structure; and a shim positioned between the first precast concrete structure and the second precast concrete structure.

Abstract: Disclosed are various construction techniques for erecting a multistory building with an elevator shaft. In accordance with the method, upper and lower shaft components are formed at an offsite facility. These shaft components are then joined together to form a segment of the larger elevator shaft. Once constructed, the segment is transported to a jobsite and erected. Once an individual segment is installed, a floor slab can be formed about the segment. Using pre-cast elevator segments simplifies and expedites the construction process. In one embodiment, each segment includes a serrated edge that facilitates a connection between the floor slab and the shaft segment. Rebar and reinforcing dowels can also be used to improve the connection. Associated shaft constructions are also disclosed.
