A construction apparatus for use within an elevator hoistway is provided. The construction apparatus includes span members, each span member having a first end, a second end and a length. Sill attachments are connected to the first end of the span members. The sill attachments are configured to rotate about and seat against a building sill. A support member connected to the second end of the span members. The support members are configured to seat against a second side of the elevator hoistway. The length of the span members is longer than a horizontal distance from the building sill to the second side of the elevator hoistway such that the span members rest in an inclined orientation with respect to a substantially horizontal axis. One or more platforms is supported by one or more forms, the platforms arranged such as to provide a working platform within the elevator hoistway.
E04B 1/34 - Extraordinary structures, e.g. with suspended or cantilever parts supported by masts or tower-like structures enclosing elevators or stairsFeatures relating to the elastic stability
E04G 1/36 - Scaffolds for particular parts of buildings or buildings of particular shape, e.g. for stairs, cupolas, domes
E04G 21/14 - Conveying or assembling building elements
E04G 3/24 - Scaffolds essentially supported by building constructions, e.g. adjustable in height specially adapted for particular parts of buildings or for buildings of particular shape, e.g. chimney stacks or pylons
An expandable platform for use within an elevator hoistway is provided. The expandable platform includes a plurality of corner members slidably connected to a plurality of side members. The corner members and the side members form an adjustable frame assembly. A plurality of extension members is connected to opposing side members. The extension members are configured to support a plurality of support surfaces. A depth and a width of the adjustable frame assembly can be adjusted to fit elevator hoistways having various depths and widths.
Construction apparatus for use within an elevator hoistway are provided. The construction apparatus include a span member having a first end and a second end. A sill attachment is connected to the first end of the span member and configured to seat against a building sill. A support member is connected to the second end of the span member and configured to seat against a second side of the elevator hoistway, wherein the second side of the elevator hoistway is opposite the building sill. A plurality of apertures is arranged on the span member and configured to allow a connection to a hoist device. The span member is configured to rotate about the sill attachment.
