Description
iZ68310 THIS INVENTION relates to improvements to building panels and particularly to building panels for use in the construction of self supporting building structures.
A number of different types of self-supporting building structures are presently available. One such type of building structure described in Australian Patent No. 477,874, comprises a plurality of arcuate panels which are interconnected in such a manner as to define a self supporting building structure without the need for trusses, columns or other supports. In this arrangement a plurality of building panels of channel shaped cross section are interconnected by crimping together the respective adjacent longitudinal flanges to form a permanent connection means. Whilst th1s arrangement is suitable for providing~a self supporting structure, ; expensive equipment is required to form the necessary jolns between the panels~ and furthermore, the ~oins formed comprise permanent joins. Other proposals have required the~use of separate fastening means to inter-; connect respective panels.~ This~necessitates ln many : . :
instances, the formation~of holes in the building panels to acaommodate the fasteners which not only is time consuming but can;lead to water leakage in an erected 25~ building.
The present invention aims to overcome or alleviate at least some of the above disadvantages by

Referring to the drawings and firstly to Fig. 1, there is illustrated a building 10 constructed in accordance with the present invention comprising a self supporting arcuate roof section 11 and a pair of upstanding end walls 12 only one of which is illustrated.
; As shown, the arcuate roof section 11 comprises a plurality of interlocked roof panels 13 each of which is preferably of the profile illustrated~in Fig. 2 and which includes a main body portion 14 and respective upstanding side portions 15 and 16. So that the roof panels 13 adopt the ~substantial1y longitudinal arcuate attitude shown in Fig. l~ the~main body portlon 1~4 is formed to have an arcuate cross section as shown in Fig. 2 whilst the side portions 15 and 16 at their , :
; lower~ends ~are deformed outwardly as at 17 and 18 respectively to compensate for the longitudinal curvature of the body portion 14. Each upstanding side portion 15 and~l6 includes a main flange portion~l9 and;20 respecti~ely, each adapted to he disposed and maintained in use in a juxtaposed attitude with the : : :
:: flange portions 19 or 20 of an adjacent panel 13 (see _ 5 _ ;:
:: ~
~ . . .
: ~ : ;. . .. - -. . : , , ., .
1~68~
Fig. 3) so as to provide the assembled roof panels 13 with the required structural rigidity. The respective flange portions 19 and 20 are surmounted by respective male and female locking ribs 21 and 22 which extend to aommon sides of the respective flange portions l9 and 20 and which in use are adapted to be engaged with one another to maintain respective panels 13 in operative engagement.
The upper ends of the flange portions l9 and 20 are also provided with respective complimentary shaped locating projections 23 and 24, the projection 23 defining a concave recess 25 of complimentary shape and size to the projection 24 so that when assembled : the projection 24 on the flange portion 20 locates neatly in the concave recess 25 in the flange portion 19 so that the flange portions 19 and 20 may be located~
: in position and in a juxtaposed attitude. This engagement also serves to prevent easy detachment of adjacent roof panels 13. As shown more clearly in Fig. 4, the male rib 21 is of generally inverted U-shaped form with one ~`
side~flange 26 thereof extending in a generally vertical direction and with the free side flange 26' thereof nclined outwardly from the vertical, in this instance .at an angle of appxox1mately 30 thereto. ~he inclination of the flange 26' is achieved by means of an inward deformation 27 formed in the base of the U-shaped male rib 2i. This provides for greater flexibility in the : :

, :: : . ' ~. . . .
.: , . . .
~, ~26~3310 flange 26' to permit the ~lange 26' to be resiliently deflected inwardly to reduce the lateral dimensions of the rib 21 to facilitate its engagement with the ~emale rib 22.
The female rib 22 is also of generally inverted U-shaped form and again one side flange 28 thereof extends generally vertically whilst the free side flange 28' thereof is slightly inclined to the vertical in this instance at an angle of approxlmately 15. The flange 28' is provided adjacent its free end with an inwardly directed deformation 29 substantially aligned with the projection 24 and defining with the latter a restricted entrance into the interior of the female rib 22.
In use and when it is desired ta interconnect :
respective panels 13, the panels 13 are positioned so that their respect1ve longitud1nal edges are ad]acent to one another;with the male and female ribs 21 and 22 respectively overlapping. ~A force is applied;between the ~.
adjacent panels 13 in a direction generally parallel to 20 ~ the side portions 15 and 16 so that the adjacent panels 13 move:relatively towards each other and so that the male rib 21 is forced through the restricted entrance of the fèmale rib 22 and into the interior thereof. This is~accomplished because the flange 26'~ of thé~male rib : 25 :~: 21 will be resiliently deformed inwardly by;virtue of the engaqement of the opposite sides: of the male rib 21 with ~ :the pxojections 24 and 29 to reduce the lateral dimensions : ' :

~83~0 of the rib 22 and at the same time engagement of the male rib 21 with the projections 24 and 29 of the female rib 22 will cause the flange 28' to be resiliently deflected outwardly thus increasing the lateral dimen-sions of the rib 22 and the width of the restrictedentrance thereof to permit the male rib 21 to pass into the interior of female rib 22.
When the end of the flange 26 moves beyond the projection 29, it will resiliently deflect outwardly to "snap lock" the male rib 21 and female rib 22 together.
At the same time, the projection 24 will locate in the recess 25 so that the flange portions 15 and 16 will be located in a juxtaposed relationship with the deformations 17 and 18 in abutment (see ~ig. 3) and maintained in that relationship by virtue of the longltudinal arcuate con~iguration of the panels 13 and the interlocked male and female ribs 21 and 220 It will be seen from Fig. 4 that the flange 26' of the male rib 21 in its operative engaged attitude is in resilient abutment with the flange 28' of the female rib 22 thus maintaining the projection 24 in co-operative engagement with the recess 25 to lock~
; ~ the side portions 15 and 16 together. Furthermore, the flanges 26 and 28 are in face to face abutment and as the flange~26' is located behind the projection 29, detachment ~; ~ 25~ of the male and female rib will be resisted.

The corrugations 34 form the main body portion 31 into a generally concave external configuration and the corrugations 34 also serve to increase the stiffness of the panels 30.
For the end walls 12 of the building, a plurality of substantially planar panels are provided, each of which are of a similar configuration to the arcuate panel 30 shown in Fig. 5 except that in this instance the main body portion of the panel is uncorrugated ~ (as shown ln dotted outlinel and of substantlally planar form as are the upstanding side flange portions so as to be in face to face abutment when engaged with adjacent planar flange portions.
In the construction of a self supporting building of the type illustrated in Fig. 1, planar paneIs 20~ Of the above described type are initially formed prefer-abIy on site with mobile roll forming apparatus. To form the arcuate roof panels 13 for thé roof section ll, the previously rolled panels are fed, on site, into deforming or corrugating apparatus to form the body portions thereof into the arcuate or trough shape shown in Fig. 2 or corrugations into the panel in the manner shown in Figs. 5 and 6~ The so formed roof panels 13 _ g _ `: :

or 30 are then i.nterconnected preferably with a connection tool 35 and in the manner shown in Fig. 7.
The tool 35 includes a first frame portion 36 supporting a pair of rollers 37 adapted for engagement with the upper surface of the female rib 22 and a second frame portion 38 which supports a further pair of rollers 39 which locate in use within the interior of the male rib 21. The frame portions 36 and 38 are slidably inter-connected to permit the rollers 37 and 39 to move towards or away from each other whilst actuating means 40 in the form of a threaded cranked member is threadedly engaged with the frame portion 38 and abutted against the frame portion 36 so that the frame portions 36 and 38 and associated rollers can be moved towards each other. Preferably the frame portion 36 includes a U-shaped handle portion 41 to permit the tool 35 to be grasped and moved along the panel ribs.
In use a first panel 13 (or 30) is laid on the ground and a second panel 13 laid on the first panel 13 with the respective male and female ribs in alignment.
The tool 3S i5 located at one end of the panels 13 and : dlsposed~ relative to the ribs in the manner shown in Fig. 7. The cranked member 40 is then rotated to move the frame portions 36 and 38 and rollers 37 and 39 : 25 towards each other to force the male rib 21 into operative engagement with the female rib as shown in Fig. 4.

ri~s to force the male rib 21 into the female rib 22 along the full length of the panels. q'his procedure may be repeated for each respective panel 13, however, preferably sets of three panels are interconnected on the ground as described above and then erected. The respective erected sets of panels 13 are then inter-connected again by the use of the tool 35 and in this instance a cord or rope is attached to the handle 41 and passed to the other side of the building where it is grasped so that the tool 35 may be drawn along the panel ribs and over the roof to interconnect the panel sets.
The opposite ends of the erected panels may then be set into a concrete foundation 42 (see Fig. 1) or alternatively fixed by an alternative anchoring arrangement.
The end walls 12 may then be formed by ~; interconnecting a plurality of planar panels. The lower ends of the interlocking planar panels may also be set into a concrete foundation 42, whilst at their upper ends th~ upstanding side portions of the planar panels `
are preferably cut away so that the projecting generally planar body portions may extend between the interlocked side portions 15 and 16 of ad~acent arcuate panels so that the end walls are supported at their upper ends.
Of course, door or wall cut-outs 43 may be formed in the end walls 12 where desired Many other arrangements may .

he provided for supporting the upper ends of the walls such as by means of a channel section fixed to the underside of the arcuate roof panels 13 which locates the upper ends of the planar panels.
The male and female rib configurations of the embodiment described above permit the panels to be interconnected by forces applied to the respective male and/or female ribs from one side of the panels only as by the tool 35. Alternatively, respective panels may be simply supported on one side and adjacent panels engaged therewith by applying a force say by body weight, to the overlapping panel to force the female rib over the male rib.
The present invention therefore provides an arrangement whereby panels may be simply interconnected to form a self supporting structure without the need for permanent interconnections such as fasteners or seams.
In the configurations illustratedt the projections 23 and 24 may be eliminated if desired. Furthermore, many different configurations of male and female ribs may be employed for interconnecting the panels in lieu of the arrangement illustrated and described above. The above arrangements may also be applied to many different building structures other than that shown in Fig. 1.

; As shown, the arcuate roof section 11 comprises a plurality of interlocked roof panels 13 each of which is preferably of the profile illustrated~in Fig. 2 and which includes a main body portion 14 and respective upstanding side portions 15 and 16.

The end walls 12 may then be formed by ~; interconnecting a plurality of planar panels. The lower ends of the interlocking planar panels may also be set into a concrete foundation 42, whilst at their upper ends th~ upstanding side portions of the planar panels `
are preferably cut away so that the projecting generally planar body portions may extend between the interlocked side portions 15 and 16 of ad~acent arcuate panels so that the end walls are supported at their upper ends.
Of course, door or wall cut-outs 43 may be formed in the end walls 12 where desired Many other arrangements may .

he provided for supporting the upper ends of the walls such as by means of a channel section fixed to the underside of the arcuate roof panels 13 which locates the upper ends of the planar panels.
The male and female rib configurations of the embodiment described above permit the panels to be interconnected by forces applied to the respective male and/or female ribs from one side of the panels only as by the tool 35. Alternatively, respective panels may be simply supported on one side and adjacent panels engaged therewith by applying a force say by body weight, to the overlapping panel to force the female rib over the male rib.
The present invention therefore provides an arrangement whereby panels may be simply interconnected to form a self supporting structure without the need for permanent interconnections such as fasteners or seams.
In the configurations illustratedt the projections 23 and 24 may be eliminated if desired. Furthermore, many different configurations of male and female ribs may be employed for interconnecting the panels in lieu of the arrangement illustrated and described above. The above arrangements may also be applied to many different building structures other than that shown in Fig. 1.
