Abstract
Abstract A self-erecting structure including a plurality of trusses joined by cables with a hydraulic system for producing relative rotation of the trusses at their juncture axes. The trusses comprise series of subelements hinged at common juncture I-beams. The cables effectively join adjacent structural subelements and the hydraulic system includes a plurality of hydraulic elements having their outer casings secured to the I-beams and their piston elements extending downwardly against the cable. Upon the application of hydraulic pressure, the outer casing and juncture I-beams move upward in opposition to the restraint of the cables causing relative rotation at the junctures of adjacent trusses to the desired angular position thereby producing an arch bay section. The curved edges of a series of arches are connected together to form the self-erecting structure.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
137 words
A self-erecting structure for use in the storage of aircraft and the like, said structure comprising a series of bay arches in a row forming a building structure, each of said arches including a plurality of truss subelements in side-by-side relationship, each of said truss subelements being hingedly connected to the next adjacent truss subelement, one end of said plurality of truss subelements being pivotally attached to a point on ground level and a pair of rotatable wheels attached to the other end to permit rolling motion along ground level during relative rotation of adjacent truss subelements, and means for erecting said structure by causing a relative rotation of adjacent truss subelements to increase the relative angle therebetween thereby forming an arch bay for attachment to other similarly configurated arch bays to produce the self-erecting building structure.
Claim 2
Dependent Claim
137 words
A self-erecting structure for use in the storage of aircraft and the like, said structure comprising a series of bay arches in a row forming a building structure, each of said arches including a plurality of truss subelements in side-by-side relationship, each of said truss subelements being hingedly connected to the next adjacent truss subelement, one end of said plurality of truss subelements being pivotally attached to a point on ground level and a pair of rotatable wheels attached to the other end to permit rolling motion along ground level during relative rotation of adjacent truss subelements, and means for erecting said structure by causing a relative rotation of adjacent truss subelements to increase the relative angle therebetween thereby forming an arch bay for attachment to other similarly configurated arch bays to produce the self-erecting building structure.
Claim 3
Dependent Claim
146 words
The self-erecting structure defined in claim 1 wherein the means for producing relative rotation between said truss subelements includes a hydraulic system comprising, in combination, a plurality of hydraulic elements corresponding structural tie members, each of said hydraulic elements having outer casings and extendible members, the outer casings of said hydraulic members being fixedly attached to the juncture between adjacent truss subelements and the lower end of the extendible member being attached to the structural tie member, each end of said structural tie member being fixed to the central lower surface of adjacent truss subelements such that the extension of the extendible member being restrained from downward movement by the structural tie member produces a corresponding upward movement of the outer casing attached to the juncture between said adjacent truss subelements thereby causing a rotation and increase of the relative angle between said adjacent truss subelements.
