Description
Received 12 March 2007 1 PREFABRICATED MODULAR BUILDING FIELD OF INVENTION This invention relates to modular building units which are prefabricated and 5 transported to location where they are erected to provide accommodation. BACKGROUND OF THE INVENTION There are many prior art documents disclosing different methods for achieving prefabricated accommodation. RU2240400 describes a shipping container-like 10 structure which concertinas into a flat package for transportation. When erected It constitutes an extremely rudimentary box shaped structure. WO 96/13402 shows a more sophisticated folding structure pivoted to a central unit provided with wheels for transportation. When on location supporting 15 bearers extend from the central unit and additional modules unfold from either side of the central unit to sit on the bearers. The side modules have gabled roofs and end walls fold out from the sides of the central unit to form closed structures. This construction is costly and only suitable for transportation by towing behind a prime mover. 20 US 4,780,996 teaches a folding portable building construction with a rigid central section and a winching system for the erection of roof members of complementary side modules. Wall members and flooring unfold after the roof members are winched into place. The winching system can be removed after 25 erection which makes the system independent of erecting cranes but adds to the cost. SU1803507 and US 4,912,891 teach further variations on the theme of a rigid central unit with unfolding side modules. However this rigid central unit 30 construction is bulky and difficult to transport. Accordingly there is a need for a prefabricated building which can be transported as a flat package like that of Amended Sheet
IPEA/AU
Received 12 March 2007 2 RU2240400 but which provides more habitable accommodation when erected on location. OBJECT OF THE INVENTION It is therefore an object of the present invention to provide a prefabricated 5 modular building which lends itself to efficient transportation and which is simply erected into habitable accommodation or which at least provides an alternative to prior art systems. STATEMENT OF THE INVENTION 10 According to the present invention, a prefabricated building module including a rectangular floor structure, three walls and a trussed roof structure enclosing a ceiling space, with two walls pivoted about the short sides of the floor structure, the third wall pivoted at its lower end to a long side of the floor structure and a roof structure pivoted at the upper end of said third wall such that said walls 15 and roof structure fold into a flat pack with the same footprint as the floor structure. Preferably the roof structure comprises a ceiling and upright roof trusses pivoted to the ceiling which fold down onto the ceiling to form a flat pack with 20 the same footprint as the floor structure. Preferably the two walls pivoted about the short sides fold down onto the floor, the ceiling folds down onto the third wall, the trusses fold down onto the ceiling and the ceiling folds down onto the other walls to form a flat pack. 25 Preferably the walls, the ceiling and the roof trusses have mechanisms which lock them in place when erect. Preferably the walls have provision for doors and windows. 30 Preferably the roof is formed from a flexible membrane which is held in sail tracks attached to the roof trusses.
Received 12 March 2007 3 Preferably the module is adapted to be used in combination with other modules to form habitable buildings of two or more modules. Alternatively the roof structure comprises rigid batten construction. 5 Preferably the floor and roof structure are adapted to extend beyond the building alignment to form external verandahs. Alternatively a method is provided whereby the roof structure and the walls of a 10 prefabricated building fold down sequentially onto the floor structure of the building to form a flat pack with the same footprint as the floor structure. Alternatively a roof structure in comprises upright roof trusses which fold down within the plan of the roof and a flexible membrane which is held in sail tracks 15 attached to the roof trusses. BRIEF DESCRIPTION OF THE DRAWINGS Figs 1 a to e show perspective views of a prefabricated building module in its various stages of erection from a flat pack to a fully erect structure. 20 Fig 2 is a side elevation of the flat pack in Fig 1 a Fig 3 is a side elevation of the first stage of erection in Fig 1 b Fig 4 is a side elevation of the second stage of erection in Fig 1c Fig 5 is a side elevation of the third stage of erection in Fig 1d Fig 6 is a side elevation of the fully erect structure of Fig 1 e 25 Fig 7 is a perspective view of two modules joined to form a building which has a rigid roof structure. DETAILED DESCRIPTION OF THE INVENTION The prefabricated building modules of the present invention are transported as 30 a flat pack 1 illustrated in Fig 1a and 2, with the same plan dimensions as a shipping container and with corner post stubs 2 to facilitate stacking. The floor Received 12 March 2007 4 3 of the module forms the base of pack 1 and end walls 4, side wall 5 and roof structure 6 are folded into flat pack 1. In the first stage of erection of the module shown in Fig 3, side wall 5 which is 5 pivoted to floor 3 at its inner lower end and ceiling 8 which is pivoted at the inner upper end of wall 5, are rotated up out of pack 1 and wall 5 is locked in its vertical position by means of locking struts 12, shown in Fig 7. In the second stage shown in Fig 4, roof trusses 7 are rotated out of the plane of ceiling 8 and locked in position at right angles to ceiling 8. 10 In the third stage of erection shown in Fig 5, ceiling 8 is raised to its horizontal position with roof trusses 7 vertical and held in place. An auxiliary winch pole (not shown) attaching to the floor structure midway along the outside of wall 5 may be used to raise ceiling 8. In the final stage shown in Fig 6, end walls 4 15 which are pivoted to floor 3 are rotated into their vertical positions and lock in place to support roof structure 6. Accordingly the erected module is structurally self supporting and two modules can be joined at their open ends to form a habitable structure with a plan area 20 of two shipping containers as shown in Fig 7. Roof covering may be provided by drawing a sail type membrane through sail tracks attached to trusses 7 and sealing the join between the two modules with a ridge cap. Alternatively a conventional rigid roof structure 9 may be provided as shown in 25 Fig 7. An outdoor verandah may be provided by extensions 10 to floor 3 beyond the module alignment and extensions 11 to roof structure 9 may also be provided to cover the outdoor verandah. Walls 4 and 5 are clad with a building material of structural and thermal ratings 30 appropriate to the location. Doors and windows are provided as required and three or more modules can be joined simply by eliminating one or more internal Received 12 March LUU'I 5 side walls of the modules. The buildings so formed can be usedi applications including living and working accommodation and- military uses such; as field headquarters and hospitals. 5 The sail type roof structure of the module can also be used independen provide a roof over, for example, a shipping container. Roof trusses 7 car4Ae pivoted to the top of the container just as they are to ceiling structure 9 rotated from their stowed position and locked in their erect position. A shade membrane can then be drawn into place through sail tracks attached to trusses 10 7 thus forming a roof over the container. VARIATIONS It will be realized that the foregoing has been given by way of illustrative example only and that all other modifications and variations as would be 15 apparent to persons skilled in the art are deemed to fall within the broad scope and ambit of the invention as herein set forth. For example various mechanical equivalents could be substituted for pivoting and locking components without departing from the inventive concept. 20 Throughout the description and claims to this specification the word "comprise" and variation of that word such as "comprises " and "comprising" are not intended to exclude other additives components integers or steps. 25 30
