Portable structure having sufficient internal structural rigidity to eliminate load-bearing perimeter support structures

摘要

A mobile structure includes first and second rigid frames and first and second horizontal roof supports supported by the rigid frame. Each of the rigid frames includes a first vertical support, a second vertical support substantially parallel to the first vertical support, and a lateral rigid frame support extending perpendicularly at least from the first vertical support to the second vertical support. The mobile structure further includes a floor under the first and second horizontal roof supports, a wheel-axle assembly under the floor, and leveling assemblies that are extendable away from the floor. Each leveling assembly is in weight-bearing and in-line relationship with respect to one of the vertical supports of the first rigid frame.

1. A portable structure having sufficient internal structural rigidity to eliminate load-bearing perimeter support structure, the portable structure comprising:
first and second rigid frames, each of the first and second rigid frames including:
at least two mutually parallel vertical supports; andmutually parallel lateral roof and floor joist supports each extending perpendicularly between the at least two vertical supports; a carriage assembly, the carriage assembly supporting a floor diaphragm coupled thereto, the carriage assembly being rigidly coupled to the lateral floor joist supports of each of the first and second frames; at least two mutually parallel horizontal roof supports supporting a roof diaphragm, the horizontal roof supports being substantially perpendicular with, and rigidly coupled to, the lateral roof supports of the first and second rigid frames; and at least one set of leveling assemblies configured to support said portable structure when in a stationary mode, each of the at least one set of leveling assemblies configured to be in weight-bearing and in-line relationship with respect to one of the vertical supports of one of the first and second rigid frames, whereby whenever the leveling assemblies are extended to and rigidly coupled to the ground, substantially all lateral forces imposed on said portable structure are transferred to the ground through the one of the first and second rigid frames.
