Abstract

A platform for indexing and clamping metal studs and like building structural members together for manufacturing metal framed walls or trusses of buildings. The platform includes spaced members for supporting studs, plates and the like placed there upon, and is sufficiently open between the spaced and properly placed members to allow applying screws to both sides of the structural members for connection of joints. The platform may be manually loaded with the appropriate framing structural members with the platform in a horizontal position with the indexing stops upward. The indexing stops are used to position studs, and powered clamps are provided to secure the studs in place against the stops. Screws may be applied to a first side of the framing, followed by the platform being rotated 180 degrees under motor or like power to expose the second side of the framing to allow the application of holding screws thereto. The indexing clamps and the movable raised plate hold the framing in place while the platform is rotated or inverted.

Dependent claims

A rotatable work platform for indexing and clamping building frame members during construction of a building frame section, comprising;

the platform structured of a plurality of spaced members defining a table-like surface at least 8 feet in width,
said platform including axles connected to
support means on each of two oppositely disposed ends of the platform,
indexing means attached to said platform for indexing building frame members in predetermined locations on said platform,
first clamping means affixed to said platform for securing building frame members against said indexing means,
second clamping means affixed to said platform for pressing building frame members inward toward a lengthwise center axis of said platform, powering means connected to said second clamping means for powering said second clamping means inward and outward toward and away from the lengthwise center axis of said platform,
rotational powering means connected to at least one of the axles for rotating said platform from a first horizontal position to an inverted horizontal position,
said support means including vertically movable carriage means supporting said axles, and powering means for raising and lowering said carriage means for elevationally raising and lowering said platform, whereby said platform can be raised to provide grade clearance for rotating said platform, and then lowered to position said platform at a horizontal suitable work-height.
