C A DEMOUNTABLE BUILDING 0 5 FIELD OF INVENTION This invention relates to demountable buildings in particular but not exclusively to a light weight demountable building able to be assembled in the absence of 0 written instructions and without the use of any tools.

_BACKGROUND ART 00 0 The problem faced in the absence or shortage of accommodation in the event of 0 natural disasters such as during and after floods, tsunami, earthquakes and cyclones and in times of war and other human conflict is known. There are also critical times in which a number of people have to be housed rapidly such as in political refugee camps and in times of population movement or displacement.

In most cases of natural disaster, countries disposed toward their more unfortunate neighbours contribute by providing teams of experienced personnel and tradesmen to erect low cost housing en masse.

In most cases the buildings erected are very temporary and include tents, and are made of a range of perishable materials for example fabric, paper or light guage metal and plastic sheets. Such primitive shelters are often inadequate in most disaster situations. More comfortable and permanent solutions are usually heavier, difficult to transport quickly and require skilled tradesmen with attendant costs to erect such buildings.

There is therefore a worldwide demand for affordable, easy to erect dwellings which can be assembled quickly without the need for experienced tradesmen, and which can be dismantled and removed easily or left as a more permanent solution without compromising universally acceptable living standards.

OBJECT OF INVENTION It is there for the object of the present invention to provide an alternate solution to temporary and semi permanent accommodation or to at least provide the public with their useful choice.

STATEMENT OF INVENTION In one aspect the invention resides in a demountable building adapted for rapid hand assembly in the absence of written instructions and without the use of tools, including in combination, a plurality of prefabricated walls or building sides,

O

00Ar Nsaid walls or sides including wall openings such as for windows and doors, each wall or side having colour-coded edges for connecting to an edge of an adjoining wall or side of the same colour, hand operated fastening means for fixing the adjoining colour-coded edges together, wherein in use, a building can be rapidly assembled by hand without recourse to any written 00 instructions or the use of any tools.

O 10 Preferably the building walls or sides are extruded hollow panels with channels or air pockets adapted to be optionally filled with foam insulation.

00 oO 0 Preferably the channels are also adapted to enable electrical and other cabling to 0 be installed in the channels.

Preferably the edges of the walls or sides are connected by simple fastening means including metal brackets which are predrilled wherein a fastener typically a bolt and wing-nut can be used to fasten the edges together by hand.

?0 Preferably the building is anchored to the ground by means of star pickets and brackets attached to the corners of the building.

Preferably the panels comprising the building walls and sides can be packaged and assembled from a flat pack kit for easy supply, transportation and storage purposes.

Preferably all the materials used in fabricating the demountable building are fully recyclable and environmentally friendly.

BRIEF DESCRIPTION OF DRAWINGS In order that the invention be better understood and put into practical effective reference will now be made to the accompanying drawings wherein; Figure 1 shows a preferred wall panel according to the invention.

Figure 2 shows detail of joining of building panels by means of simple hand operated fittings.

Figure 3 shows a corner fitting according to the invention.

Figure 4 shows support of the building by means of star pickets at the corners of the building.

Figure 5 shows detail of a roof assembly according to the invention, and 00

O

N Figure 6 shows various views of a demountable building according to the invention.

DETAILED DESCRIPTION OF DRAWINGS 0 Referring now to the drawings and initially to Figure 1, there is shown a preferred wall or side panel (10) according to invention. The wall or side panel is 00 constructed of extruded plastic namely PVC and comprises a series of vertical channels (12) for the insertion of cabling or insulation foam if required.

Also shown is a window opening (14) which has been lined by a plastic liner OO (14a) which accommodates the thickness of the panel.

S At the edge of the panel there is also shown a tongue (10 a) on one edge and a groove (10 Ob) on the other edge for assembling panels together to form a wall.

Referring now to Figure 2 there is shown the joining of panels by the use of hand operable fixtures such as wing-nuts (18) and bolts (22) and corner strips (26) with pre-drilled holes to accommodate the bolts and wing-nuts. It .0 will be evident where a wall is to be joined perpendicularly to another wall that an end plate (28) will be required and that tightening of by hand the nuts, will provide a fairly firm joint.

Although not shown, the edges of adjoining panels would be colour coded as well as the edges and the angle corner strips for appropriate panels to be assembled together, Figure 3 shows an exploded view of a corner of a demountable building according to the invention wherein panels (36) have a tongue and groove configuration are clipped together and fastened by means of a corner angle (38) with wing-nuts (42) and bolts (46).

;0 Figure 4 shows the assembled wall of Figure 3 wherein the building (48) is supported by a star picket (50) with a bracket (52) supporting the floor of the building at each corner.

Figure 5 shows detail of a roof assembly wherein the roof (54) is pitched at an angle by means of corner angles (58) joins in co-operation with wing-nuts (62) and bolts to fasten the roof to the wall (68).

Figure 6 shows a perspective side (72) and end view (74) of a typical demountable building according to the invention. The building can be mounted on a floor (76) with joists (78) having star pickets (80) at each corner as well as where a central bearing joist (82) is required.

Window openings are typically as described in Figure 1 and the roof is connected to the walls by assembly means of Figure 00 4 C VARIATIONS Ct It will of course be realized 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.

00 Throughout the description and claims this specification the word "comprise" and variations of that word such as "comprises" and "comprising", are not intended to C 10 exclude other additives, components, integers or steps.
