Definitions

• THIS INVENTION relates to a frame structure and to a building incorporating such a frame structure.
• the present invention seeks to provide a novel and useful frame structure having rigid frame sections which do not bend during erection.
• the invention resides in a frame structure having collapsed and erected conditions, comprising a plurality of rigid frame sections in end to end relationship, each frame section being hingedly connected to the neighbouring frame section, and erection means for effecting relative pivotal, movement between neighbouring frame sections to erect the frame structure.
• said erection means comprises means for moving the outermost frame sections together.
• Such means may comprise at least one cable having one end thereof connected to one of the outermost frame sections and the other end thereof fixed to a power device connected to the other outermost frame section whereby operation of the power device to tension the cable effects movement of the outermost frame sections in a direction towards each other.
• the cable is positioned on the underside of the frame sections.
• said cable passes through guideways mounted on the rigid frame sections.
• the guideways are spaced from the rigid frame sections.
• the guideways are supported on arms mounted on, and extending outwardly of, the rigid frame sections.
• said cables Preferably there are a plurality of said cables arranged in pairs with one pair disposed to each side of the central longitudinal axis of the frame structure.
• said arms supporting the guideways for each cable extend outwardly and downward from the frame structure when the latter is in the collapsed position and are arranged to swing inwardly upon tensioning of the cables.
• the inward swinging movement of the arms may be accommodated in any suitable way such as by bending of the arms or pivoting about a hinge incorporated in or connected to each arm.
• Means may be provided to lock neighbouring frame sections against relative pivotal movement following erection of the frame structure.
• Such locking means may comprise fastening means which secure the frame sections together.
• the invention resides in a building construction incorporating at least one frame structure of the form described above.
• the invention resides in a building construction comprising a plurality of frame structures of the form described above positioned at spaced intervals along the length of the building, and a plurality of purlins extending between the frame sections.
• said purlins support roofing material which provides a roof for the building construction.

• Fig. 14 is a schematic view of a frame structure according to a fifth embodiment.
• the first embodiment is directed to the construction of a framed building to provide unrestricted cover for a large area.
• the frame building may be used for any suitable purpose such as an aviation hanger, a manufacturing or processing plant, a storage facility, or a venue for functions such as sports, displays or entertainment.
• the framed building 10 comprises a plurality of transverse frame structures 11 spaced along the length of the building.
• the frame structures support purlins 13 which extend along the length of the building and which support roofing material 15 of any suitable form such as metal sheeting.
• the frame structures 11 each have a collapsed condition (as shown in Fig. 2 of the drawings) and an erected condition (as shown in Figs. 1 and 3 of the drawings) in which the frame structure provides a supporting arch within the building.
• Each frame structure 11 comprises a plurality of frame sections 21 in end to end relationship with each frame section being hingedly connected by hinge means 23 to neighbouring frame section.
• the frame sections 21 rest on the ground 24 when the frame structure is in the collapsed condition.
• the frame sections 21 may be of any suitable construction.
• outer frame sections 21a each comprise a support leg 25 in the form of a metal beam and a roof portion 27 in the form of a truss rigidly mounted on the support leg 25.
• the intermediate frame sections 21b between the outer sections 21a are each in the form of a truss.
• the frame sections 21a and 21b have end faces 31 as shown in Figs. 7 and 8.
• the end faces 31 of neighbouring frame sections are angularly spaced with respect to each other, as shown in Fig. 7.
• the end faces of neighbouring frame sections are in abutting engagement and are fixed to each other by any suitable means such as bolts 35, as shown in Fig. 8.
• Erection means are provided for moving the outermost frame sections 21a of the frame structure inwardly to cause the frame structure to move from the collapsed condition to the erected condition.
• the erection means comprises erecting cables 39 positioned in pairs below the frame structure, there being two pairs of cables disposed equally one to each side of the central longitudinal axis of the frame structure.
• One end of one pair of cables is connected at 36 to the supporting leg 25 one of the outermost frame sections 21a, and the corresponding end of the other pair of cables is similarly connected at 38 to the supporting leg.
• the other end of each cable is connected to a power device 40 such as a hydraulic ram mounted on the support leg of the other outermost frame section 21a.
• the cables extend through guideways 41 at spaced intervals along the frame structure.
• the guideways are in the form of tubular elements, some of which are mounted directly on the underside of the frame sections and others of which are mounted on arms 43 extending downwardly from the frame sections.
• a particular benefit of the building construction according to the embodiment is that the purlins and roofing material can be installed on the frame structures while the latter are in the collapsed condition. In this way, the work can be carried out at, or relatively close to, ground level thereby reducing the need for scaffolding and other equipment required at high working heights.
• the building can then be completed by erecting the frame structures 11, as previously described.
• the roofing material bends to accommodate angular movement of neighbouring frame sections 21 about hinges 23.
• each guideway 41 is mounted on an arm 43.
• the arms 43 extending downwardly and outwardly of the frame section, as shown in Figs. 10 and 11 of the drawings.
• the arms progressively increase in length in the direction towards the centre of the structure for the purpose of accommodating greater bending moments in the centre region.
• the arms are caused to swing inwardly into a position directly beneath the frame structure.
• the arms are caused to swing inwardly under the influence of the forces imposed on them as the erecting cables straighten during tensioning.
• the inward movement of the cables as they straighten can be accommodated in any suitable way such as by constructing the arms of material which can bend to provide the movement or incorporating a hinge (such as a plastic hinge) either in each arm or at the junction between the arm and the frame structure.
• the frame sections 21 are substantially straight.
• the frame sections may, however, be of any other suitable configuration.
• the uppermost frame section 21 is arcuate thereby providing an arch formation when the frame structure is erected.
• outer frame sections each included a support leg and a roof section integral with eachother. In other arrangements the outer section may form only the support leg.
• the fourth embodiment which is illustrated in Fig. 13.
• the erecting cables may be desirable in certain situations for the erecting cables to extend between the intermediate frame sections immediately adjacent the outer frame sections so as not to operate the latter.
• a separate system of any suitable form is provided for controlling angular movement of the support legs independently of angular movement of the intermediate frame sections.
• the support legs are arranged to extend inwardly of the frame structure when the latter is in the collapsed condition.
• a system separate of the cables is of course required to control movement of the support legs.
• one of the pivotal support sections extends inwardly of the frame structure when the latter is in the collapsed condition and the other support section extends outwardly of the frame structure.
