Abstract
Abstract There is described a prefabricated structure for erecting a building, that comprises bays hinged together which can take a position with a reduced volume and a position of extension, in which each bay comprises in the structure erecting condition and from the geometrical point-of-view, two pairs of dihedrons facing one another by pairs and comprising respectively the roof, the underflooring and the frontages of the bay, each dihedron comprising two sides hinged together along the dihedron intersection line and the junction areas between the dihedrons are each comprised of a truncated polyhedron comprising four side surfaces hinged together along their converging edges, said edges converging towards an apex located outside the imaginary right angle between the intersection lines of two dihedrons, two of those edges opposite the converging edges of the polyhedron being hingedly joined to one of the dihedrons, the structure further comprising means for stabilizing the dihedron angles in the bay extension condition, and the succeeding bays being hingedly connected together along the adjacent circumferential edges thereof.

Claim 1
Independent Claim
165 words
Prefabricated structure for erecting a building, that comprises bays hinged together which can take a position with a reduced volume and a position of extension, in which each bay comprises in the structure erecting condition and from the geometrical point-of-view, two pairs of dihedrons facing one another by pairs and comprising respectively the roof, the underflooring and the frontages of the bay, each dihedron comprising two sides hinged together along the dihedron intersection line and the junction areas between the dihedrons are each comprised of a truncated polyhedron comprising four side surfaces hinged together along their converging edges, said edges converging towards an apex located outside the imaginary right angle between the intersection lines of two dihedrons, two of those edges opposite the converging edges of the polyhedron being hingedly joined to one of the dihedrons, the structure further comprising means for stabilizing the dihedron angles in the bay extension condition, and the succeeding bays being hingedly connected together along the adjacent circumferential edges thereof.
Claim 2
Dependent Claim
165 words
Prefabricated structure for erecting a building, that comprises bays hinged together which can take a position with a reduced volume and a position of extension, in which each bay comprises in the structure erecting condition and from the geometrical point-of-view, two pairs of dihedrons facing one another by pairs and comprising respectively the roof, the underflooring and the frontages of the bay, each dihedron comprising two sides hinged together along the dihedron intersection line and the junction areas between the dihedrons are each comprised of a truncated polyhedron comprising four side surfaces hinged together along their converging edges, said edges converging towards an apex located outside the imaginary right angle between the intersection lines of two dihedrons, two of those edges opposite the converging edges of the polyhedron being hingedly joined to one of the dihedrons, the structure further comprising means for stabilizing the dihedron angles in the bay extension condition, and the succeeding bays being hingedly connected together along the adjacent circumferential edges thereof.
Claim 3
Dependent Claim
60 words
Prefabricated structure as defined in claim 1, in which the dihedron sides have the same width and the locus of the junction area apexes is located in the reduced-volume condition of the structure, at a distance from the imaginary intersection point between the intersection lines of both dihedrons, which is substantially equal to half the width of the dihedron sides.
Claim 4
Dependent Claim
113 words
Prefabricated structure as defined in claim 1, which comprises two complementary separate parts that comprises in turn, the one a plurality of bays hinged together, each bay having one dihedron to form the roof and two facing dihedrons to form frontage portions as well as said junction areas, and the other part a plurality of bays hinged together each one of which has a dihedron to form the underflooring and two facing dihedrons to form frontage portions as well as said junction areas, the frontage portions of each structure part having a height which is equal to a fraction of the total frontage height and said portions comprising means to connect same together.
Claim 5
Dependent Claim
48 words
Prefabricated structure as defined in claim 1, in which said means for stabilizing the dihedron angles in the bay extension condition, comprise cross-beams connected together which are mounted inside the volumes bounded by the dihedrons at the level of the intersection of the hinging lines between adjacent bays.
Claim 6
Dependent Claim
92 words
Prefabricated structure as defined in claim 1, in which the polyhedron bounding the junction area comprises on the one hand, two side surfaces each lying in the same plane as one side of one dihedron bounding the roof, the frontage portion and the underflooring and extending said dihedron sides without discontinuity and on the other hand two sides each lying in a plane cross-wise to the plane of the one side of the second dihedron concerned by the corresponding junctions area and which sides are hinged relative to said second dihedron sides.
Claim 7
Dependent Claim
48 words
Prefabricated structure as defined in claim 5, in which the junction areas connecting the underflooring to the frontages form legs or pylons for heightening the underflooring, the dihedron sides bounding the frontage portions being extended without discontinuity by two side surfaces of that polyhedron bounding the junction area.
Claim 8
Dependent Claim
41 words
Prefabricated structure as defined in claim 1, in which in the extension condition, the angles of those dihedrons forming the frontage portions of one end the same bay are not equal to one another so as to form a curved structure.
Claim 9
Dependent Claim
44 words
Prefabricated structure as defined in claim 1, in which the sides of those dihedrons forming the roof and underflooring are comprised of two triangular segments hingedly connected together along the one side thereof, running in parallel relationship and extending diagonally through the dihedron side.
Claim 10
Dependent Claim
48 words
Prefabricated structure as defined in claim 1, in which the dihedron and polyhedron sides are comprised of rigid panels and said panels are connected together along the adjacent edges thereof by means of flexible connecting sectional shapes, the panels and the connecting sectional shapes forming a monocoque structure.
Claim 11
Dependent Claim
92 words
Prefabricated structure as defined in claim 9, which comprises two types of connecting sectional shapes, a first type to connect panels which in the reduced-volume condition of the structure lie substantially in the same plane and a second type to connect panels which in the reduced-volume condition of the structure lie substantially one against the other, both types of sectional shapes having a center portion which is curvable and located between said panels, and two flanges located on either side of the center portion to fasten the sectional shape to the panels.
Claim 12
Dependent Claim
76 words
Prefabricated structure as defined in claim 9, in which each panel is comprised of two half-shells from rigid synthetic material, each half-shell having along the outline thereof a rim for the assembly together by means of assembly members, the half-shells having an inner circumferential groove for receiving a gasket and a series of recesses for receiving a heat-isolation material, the connecting sectional shapes being sandwiched with their fastening flanges between the assembly rims of the half-shells.
Claim 13
Dependent Claim
43 words
Prefabricated structure as defined in claim 1, which comprises a series of skeleton frames bounding the circumference of the dihedrons and the polyhedrons and the polyhedron sides, rigid panels for filling said frames as well as members for hingedly connecting the frames together.
