OPENTECHNICAL PUBLICATION OT-2026-000001175 Systems and methods for modular construction Published: 2026-09-15T19:03:58.453934Z Permanent URL: https://opentechnical.org/p/OT-2026-000001175 Categories: Lifting, Positioning & Manipulation > Hoists and Cranes ------------------------------------------------------------------------ ABSTRACT A connection assembly for modular construction includes an upper junction connector coupled to an upper end of a column. The upper junction connector includes an upper end that has a planar upper surface, a recessed surface, and at least one connector sidewall extending between the upper surface and the recessed surface. The recessed surface and the at least one connector sidewall define a contiguous recessed area in the upper end that extends to second, third, and fourth edges of the upper end of the connector. A slot extends through the upper end adjacent to an interior surface of a column sidewall. A transverse bore extends through the first column sidewall proximate to and aligned with the slot. ------------------------------------------------------------------------ OpenTechnical publication OT-2026-000001175 Published 2026-09-15T19:03:58.453934Z https://opentechnical.org/p/OT-2026-000001175
