Multi-story building having prefabricated stair and elevator modules

A multi-story building, comprising:

• one or more levels formed from prefabricated interior and exterior panels and substantially parallel to a reference ground plane defined by a foundation;
• a first prefabricated stairwell and elevator shaft module configured to be adjacent to at least one level of the one or more levels, the first prefabricated stairwell and elevator shaft module comprising:
• four vertical members arranged orthogonal to the ground plane;
• four transverse members fixedly attached to upper and lower distal ends of the four vertical members with corner support members;
• and
• four longitudinal members fixedly attached to upper and lower distal ends of the four vertical members with the corner support members,
• wherein the four vertical members, four transverse members, and four longitudinal members form side edges of the first module and define an interior space, wherein the first module is configured to form a segment of one or more of an elevator shaft and a stairwell within the interior space, the segment having a height corresponding to a single level of the one or more levels, the segment configured to communicate between levels of the multi-story building, and the segment being a self-supporting structure, and
• wherein the corner support members each comprise at least one anchor hole configured to receive and engage with a lifting hook for lifting and placement of the prefabricated stairwell and elevator shaft module at a construction site for the multi-story building prior to installation of the prefabricated interior and exterior panels;
• and
• a second prefabricated stairwell and elevator shaft module,
• wherein the first module is configured to align with and stack upon the second module,
• wherein the first module is configured to attach to the second module with one or more longitudinal joining members,
• wherein each longitudinal joining member is formed from a continuous piece of metal having through holes formed therein that are configured to receive fasteners that join with corresponding longitudinal members of the second module and of the first module stacked upon the second module, and wherein:
• the segment of the elevator shaft comprises one or more engagement features configured to engage and retain elevator system components,
• at one of the side edges of the first module, the four longitudinal members have oblique distal ends that extend past the corner support members to form a space dimensioned for the elevator system components, and
• the elevator system components comprise at least one elevator rail or at least one elevator counterweight.
