Description

WO 2009/126985 PCT/AU2008/000718 1 COLLAPSIBLE/DEMOUNTABLE BUILDING 5 FIELD OF THE INVENTION This invention relates to buildings in particular demountable or collapsible buildings such as dormitories and military operating theatres which are easily collapsible and erected 10 particularly for field emergency operations and the like. BACKGROUND OF THE INVENTION 15 Prior art demountable or collapsible buildings are known. The application for such buildings in emergency situations such as natural disasters and in war zones is well known. Examples include remote housing used for various industries such as in mining and emergency housing in floods and cyclone caused disasters. Problems encountered with such situations include the fact that remoteness of location often acts as a barrier to 20 such housing being supplied quickly, in great quantities and where the building structures are affordable and provide longevity in the face of adverse weather and terrain conditions. Portable houses often require wide roads with added expense of pilot vehicles and heavy machinery to carry the portable houses to the locations required. Temporary portable buildings in the form of tents also require constant upkeep of 25 guyropes, ground fixtures and fittings which are often difficult to affix successfully in many geographical locations.

WO 2009/126985 PCT/AU2008/000718 2 Furthermore where tents are used as operating theatres, there is a problem with cleanliness and hygiene due to the use of fabric such as canvas and fabric in the structure. 5 Where tents are to be used, inclement weather is also a major deterrent especially where there is heavy precipitation wherein the tents become saturated with water and are unpleasant to use as a form of shelter. Military application of tents as operating theatres is obviously an example where hygiene is very much an issue. In general, tents and current examples of portable shelters and buildings also require a long time to 10 assemble and to remove from sites. As previously mentioned more substantial buildings such as compact houses and mobile homes often require transport to the site requiring a pilot vehicle and a large transporter or truck. These units are usually transported in a completed form and often cannot get to 15 remote locations easily. Some examples of transportable homes are erected on site and can be transported in sections. Such buildings however require the use of tools and often a skilled trades person to erect the building. In these examples there is often the attendant need of 20 having to have a power supply on hand and the possibility of requiring heavy machinery to lift panels and roofs into position. Where tents are used as mentioned above, there is often a significant footprint required in terms of land space due to the ropes of the tent as an addition to the disadvantages 25 already listed.

WO 2009/126985 PCT/AU2008/000718 3 Furthermore where prior art buildings are required to be erected, the site often has to be prepared by making it level and relatively clear of debris and natural vegetation. Viability and type of prior art building regiment is constrained by space, access to the space and the type of terrain which will determine ultimately the actual portable unit to be used. 5 OBJECT OF THE INVENTION It is therefore object of the present invention to provide an improved demountable or 10 collapsible building which seeks to ameliorate or eliminate some of the problems and limitations of prior art portable buildings or to at least provide the public with a useful choice. 15 STATEMENT OF INVENTION According to one but not necessarily the only aspect, the invention resides in a collapsible or demountable building comprising in combination, at least a roof and a floor; 20 at least a pair of opposed walls; each wall connecting the roof and the floor on the same side; the walls comprised of two or more side panels foldably hinged together; one or more collapsible scissors action braces associated with each wall; a mechanism associated with each scissors action brace adapted to raise or collapse 25 the brace; wherein an operation, WO 2009/126985 PCT/AU2008/000718 4 the building is placed in a storage and / or transportable configuration when the scissor braces are in the collapsed or non deployed position and wherein the roof and floor overlie and sandwich the side panels, and wherein by deploying the scissor braces to lift the roof panel away from the floor, the 5, side panels are unfolded to form the walls wherein the walls and the roof are supported by the fully deployed and extended scissor braces in a single operation to erect the building. Preferably the mechanism to raise or collapse the scissor braces are housed between 10 adjacent floor joists supporting the floor panels. Preferably the floor joists are located and positioned so that a user can lift by means of a forklift the building in either the erected or demounted configurations such as when the demounted buildings are stacked on top of one another for transportation or storage 15 purposes.

BRIEF DESCRIPTION DRAWINGS 15 In order that the invention be better understood and put into practical effect, reference will now be made to the accompanying illustrations wherein: Figure 1 shows a preferred embodiment of the invention in the fully erected position. 20 Figure 2 to Figure 5 show the building of Figure 1 being erected from the demounted position to the fully erected position of Figure 1. DETAILED DESCRIPTION OF THE INVENTION 25 Referring now to Figure 1 there is shown a preferred demountable or collapsible building according to the invention. To aid in clarity of description and to facilitate a fully enabling WO 2009/126985 PCT/AU2008/000718 9 disclosure, the numbering of components in each drawing or illustration has been kept consistent throughout the following passages. The collapsible or demounted building (10) is shown comprising a roof panel (12) 5 preferably of light gauge aluminium or steel sheet metal having a sandwich type construction with core insulation material located between a pair of sheets. The floor panel (14) is similarly of light weight gauge metal and is supported by a plurality of spaced floor joists (16, 18, 20). The walls (22, 24) of the building comprise a 10 pair of side panels (22a, 22b, 24a, 24b). The top side panel (22a, 24a) is permanently hinged to the roof (12) and the bottom side panel (22b, 24b) is permanently hinged to the floor (14). The side panels are of equal dimensions or size and are also hinged together (22c, 22d). 15 Although in this example there are two side panels, in various embodiments there can be three or four side panels depending of the height of the building as required. Shown associated with the side panels are the scissor action braces (26, 28) which raise the roof from the floor. The scissor action braces are operated by a screw-jack mechanism (30, 32) which opens or closes the scissors when deploying or collapsing the scissored 20 members. The demountable building also has end walls (34) which in a preferred embodiment are permanently hinged to the floor panel. The end walls and the side walls incorporate door (36) and window apertures respectively (38, 40, 42). 25 WO 2009/126985 PCT/AU2008/000718 10 In this example the scissor braces are operated a mechanism wherein one leg (26a) of a scissor brace is pivotal about a point (20a) in a floor joist (20) and wherein a corresponding end of the other scissor leg (26b) is attached to carriage (44) (not shown) movable in a track (46). Moving the carriage along the track by means of a screw-jack to 5 splay the scissors brace would result in collapsing the demountable building in a single action and wherein moving the scissors legs of a brace together by the screw-jack raises or erects the demountable building. Referring now to Figure 2 there is shown the demountable building in the fully collapsed 10 position wherein the scissor braces (26, 28) are shown in the completely folded or non deployed position and the roof (12) and floor panels (14) overlie the side panels of the walls (22, 24) which are hinged inwardly and are thereby sandwiched by the roof and floor panel. 15 Figure 3 shows the deployment of the scissor braces (26, 28) which raise the roof panel (12) from the floor panel (14) thereby also unfolding the side panels (22a, 22b, 24a, 24b) of the walls. Figure 4 shows further deployment of the scissor braces lifting the roof panel upwards 20 away from the floor panel wherein the side panels start to fold further outwards. Also shown are one of the end wall panels (48) which are permanently hinged to the floor panel (14). Figure 5 shows the scissor braces (26, 28) in their fully extended and operational 25 position wherein the side panels (22a, 22b, 24a, 24b) are now vertically aligned and form the walls of the demountable building. The end walls (48) of which only one is shown WO 2009/126985 PCT/AU2008/000718 11 can now be raised to attach to the roof (12) thereby completing the erection of the building as is shown in Figure 1. VARIATIONS 5 It will of course be realised that while the foregoing has been given by way of illustrative example of this invention, all such and other modifications and variations thereto as would be apparent to persons skilled in the art are deemed to fall within the broad scope and ambit of this invention as is herein set forth. 10 Throughout the description and claims this specification the word "comprise" and variations of that word such as "comprises" and "comprising", are not intended to exclude other additives, components, integers or steps. 15 20 25
