Abstract
Abstract A modular building unit including a moment resistant space frame. The space frame includes an elongate lower frame assembly and an elongate upper frame assembly overlying and spaced above the lower assembly. A pair of upright support posts adjacent one set of ends of the frame assemblies and another pair of upright support posts adjacent the other set of ends of the frame assemblies provide the sole vertical support for the upper frame assembly above the lower frame assembly. The upper and lower sets of ends of the support posts are secured to the frame assemblies in such a manner as to provide moment resistant connections therebetween. Further, the support posts at one set of ends of the frame assemblies are of a different cross section than the support posts at the opposite ends of the frame assemblies to minimize effects of vibrations on the structure.

Total Claims: 7
Claim 1
Independent Claim
281 words
A moment resistant space frame for a modular building unit comprising an elongate, horizontally disposed lower frame assembly, an elongate, horizontally disposed upper frame assembly overlying and spaced above said lower frame assembly, with one end of the upper frame assembly positioned over one end of the lower frame assembly and the opposite end of the upper frame assembly positioned over the opposite end of the lower frame assembly, said upper frame assembly being supported above said lower frame assembly solely by a pair of upright support posts adjacent one set of ends of said frame assemblies and another pair of upright support posts adjacent the opposite set of ends of said frame assemblies, said posts in each of said pairs being secured adjacent their lower set of ends to said lower frame assembly and secured adjacent their upper set of ends to said upper frame assembly in a manner to provide moment resistant connections between said upper and lower ends of the posts and said frame assemblies, and wherein said posts in said pair adjacent one set of ends of the frames assemblies have cross sections as viewed from above which differ from the cross sections as viewed from above of the posts in the pair adjacent the opposite set of ends of the frames, with a post in said pair adjacent one set of ends of the frame assemblies comprising a beam having a web and flanges projecting outwardly therefrom and said beam is disposed in said frame with the web thereof occupying a plane substantially paralleling a vertical plane occupied by the longitudinal axis of the frame and with the flanges thereof disposed substantially normal to said plane.
Claim 2
Dependent Claim
281 words
A moment resistant space frame for a modular building unit comprising an elongate, horizontally disposed lower frame assembly, an elongate, horizontally disposed upper frame assembly overlying and spaced above said lower frame assembly, with one end of the upper frame assembly positioned over one end of the lower frame assembly and the opposite end of the upper frame assembly positioned over the opposite end of the lower frame assembly, said upper frame assembly being supported above said lower frame assembly solely by a pair of upright support posts adjacent one set of ends of said frame assemblies and another pair of upright support posts adjacent the opposite set of ends of said frame assemblies, said posts in each of said pairs being secured adjacent their lower set of ends to said lower frame assembly and secured adjacent their upper set of ends to said upper frame assembly in a manner to provide moment resistant connections between said upper and lower ends of the posts and said frame assemblies, and wherein said posts in said pair adjacent one set of ends of the frames assemblies have cross sections as viewed from above which differ from the cross sections as viewed from above of the posts in the pair adjacent the opposite set of ends of the frames, with a post in said pair adjacent one set of ends of the frame assemblies comprising a beam having a web and flanges projecting outwardly therefrom and said beam is disposed in said frame with the web thereof occupying a plane substantially paralleling a vertical plane occupied by the longitudinal axis of the frame and with the flanges thereof disposed substantially normal to said plane.
Claim 3
Dependent Claim
190 words
A moment resistant space frame for a modular building unit comprising an elongate, horizontally disposed, lower frame assembly, an elongate, horizontally disposed, upper frame assembly overlying and spaced above said lower frame assembly with one end of the upper frame assembly positioned over one end of the lower frame assembly and the opposite end of the upper frame assembly positioned over the opposite end of the lower frame assembly, said upper frame assembly including a pair of elongate, laterally spaced trusses extending along opposite sides of said upper frame assembly and a substantially rectangular, horizontally disposed channel frame secured to the undersides of said trusses and extending peripherally about said upper frame assembly, said channel frame having flanges thereon facing inwardly of the upper frame assembly to present supportive shoulders within the upper frame assembly, and a plurality of upright support posts disposed adjacent opposite ends of said frame assemblies secured adjacent their lower set of ends to said lower frame assembly and secured adjacent their upper set of ends to said upper frame assemblies through moment resistant connections to support said upper frame assembly over said lower frame assembly.
Claim 4
Dependent Claim
190 words
A moment resistant space frame for a modular building unit comprising an elongate, horizontally disposed, lower frame assembly, an elongate, horizontally disposed, upper frame assembly overlying and spaced above said lower frame assembly with one end of the upper frame assembly positioned over one end of the lower frame assembly and the opposite end of the upper frame assembly positioned over the opposite end of the lower frame assembly, said upper frame assembly including a pair of elongate, laterally spaced trusses extending along opposite sides of said upper frame assembly and a substantially rectangular, horizontally disposed channel frame secured to the undersides of said trusses and extending peripherally about said upper frame assembly, said channel frame having flanges thereon facing inwardly of the upper frame assembly to present supportive shoulders within the upper frame assembly, and a plurality of upright support posts disposed adjacent opposite ends of said frame assemblies secured adjacent their lower set of ends to said lower frame assembly and secured adjacent their upper set of ends to said upper frame assemblies through moment resistant connections to support said upper frame assembly over said lower frame assembly.
Claim 5
Dependent Claim
266 words
A moment resistant space frame for a modular building unit comprising an elongate, horizontally disposed lower frame assembly, an elongate, horizontally disposed upper frame assembly overlying and spaced above said lower frame assembly, with one end of the upper frame assembly positioned over one end of the lower frame assembly and the opposite end of the upper frame assembly positioned over the opposite end of the lower frame assembly, said upper frame assembly being supported above said lower frame assembly by a pair of upright support posts adjacent one set of ends of said frame assemblies and another pair of upright support posts adjacent the opposite set of ends of said frame assemblies, said posts in each of said pairs being secured adjacent their lower set of ends to said lower frame assembly and secured adjacent their upper set of ends to said upper frame assembly in a manner to provide moment resistant connections between said upper and lower ends of the posts and said frame assemblies, said posts in said pair adjacent said one set of ends of said frame assemblies each having a first cross-sectional configuration and the posts in the pair adjacent the opposite set of ends of said frame assemblies each having a second cross-sectional configuration which is dissimilar from said first cross-sectional configuration, with a post in said pair adjacent said one set of ends of said frame assemblies comprising a Beam having a web and flanges projecting outwardly therefrom and a post in the pair adjacent the opposite set of ends of the frame assemblies having a tubular cross section.
