DETAILED DESCRIPTION OF THE INVENTION

It should be noted in the following description that like or the same reference numerals in different embodiments denote the same or similar features.



FIG. 1 shows a first 600 mm wide building panel 50 according to a preferred embodiment of the present invention. The building panel 50 comprises a rectangular plate body 52 having four spaced longitudinal formations 60 along one side thereof.


The plate body 52 comprises a flat first side 53, an opposite flat second side 54, ends 55, and lateral edges 56. The first side 53 comprises a flat planar surface 58. The four spaced longitudinal formations 60 are disposed along the second side 54, each extending between the ends 55 and spaced laterally between the lateral edges 56.


The four formations 60 are disposed symmetrically about a center line extending between the ends 55 of the second side 54. The formations 60 comprise two first formations 60a adjacent the respective lateral edges 56 and two second formations 60b spaced inwardly from the first formations 60a.


Each longitudinal formation 60 in the embodiment generally comprises a channel section having spaced side portions 62 extending perpendicularly from the second side 54 and a band portion 64 extending parallel to the second side 54, and thus spaced and parallel to the planar surface 58. The band portion 64 defines a work surface spaced from the first side 53.



FIG. 20 shows the series of folding steps in forming the building panel 50 from a single flat piece 70 of sheet metal. Starting from a flat piece 70 of sheet metal at the bottom of FIG. 20, the series of folding steps is shown (moving upwardly in FIG. 20) starting with folding of side sections 72 of the flat piece 70 to form the formations 60b, and then folding the side sections 72 toward a central section 74 of the second side 54 to form the formations 60a. These folding steps can be performed via a metal folding machine. The formations 60 act as ribs and strengthen the building panels 50.


Referring back to FIG. 1, portions of the side sections 72 adjacent the second side 54 are joined thereto via a metal clinching process at spaced points 76, such as by use of the TOG-L-LOC™ (registered) machine and process. This forms the general structure of the building panel 50.


A number of spaced rod apertures 78 are formed in the building panel 50 extending from the first side 53 to the second side 54. Central apertures 78a are formed along the centre 25 line of the second side 54 and side apertures 78b are formed respectively between the formations 60a and 60b. A number of spaced service line apertures 79 are also formed in the side portions 62 of the formations 60. The apertures 79 of the formations 62 are respectively aligned and extend between the lateral edges 56.


In the embodiment, the building panel 50 is 600 mm wide between the lateral edges 56, 1200 mm long between the ends 55 and 60 mm thick between the planar surface 58 and the band portions 64.



FIG. 2 is shows a footing 90 for the building system of the present invention. The footing 90 is generally J-shaped in cross-section and comprises a base portion 91 and first and second upwardly extending side portions 92 and 93 which respectively extend from longitudinal edges of the base portion 91, to define a channel 94 therebetween. The first side portion 92 extends longer than the second side portion 93 from the base portion 91.


The footing 90 is 600 mm wide and the channel 94 is slightly over 60 mm wide between the side portions 92 and 93.

FIG. 3(
c) shows a building panel 153, which is also similar to the building panel 50 except that the building panel 153 is 300 mm wide and only includes the formations 60a.



FIG. 22 shows the steps in forming the building panel 153 from a flat piece 70c of sheet metal. It can be seen that the side sections 72 are folded toward the central section 74 to form the formations 60a.



FIG. 3(
d) shows a building panel 154, which is similar to the building panel 153 except that the building panel 154 is 150 mm wide. FIG. 23 shows the steps in forming the building panel 154 from a flat piece 70d of sheet metal.



FIG. 3(
e) shows a building panel 155, which is similar to the building panel 154 except that the building panel 155 is 100 mm wide. FIG. 24 shows the steps in forming the building panel 155 from a flat piece 70e of sheet metal.



FIG. 3(
f) shows a building panel 156, which is similar to the building panel 155 except that the building panel 156 is 75 mm wide. FIG. 25 shows the steps in forming the building panel 156 from a flat piece 70f of sheet metal.



FIG. 3(
g) shows a building panel 157, which is similar to the building panel 50a except that the building panel 157 is essentially a half-panel of the building panel 50a. The building panel 157 is 300 mm wide and only includes one pair of formations 60a and 60b at one lateral edge 56 thereof, with the other lateral edge 56 being free of formations 60.



FIG. 26 shows the steps in forming the building panel 157 from a flat piece 70g of sheet metal, at which only one of the side sections 72 is folded.



FIG. 3(

FIG. 27 shows the steps in forming the building panel of 158 from a flat piece 70h of sheet metal.



FIG. 3(
i) shows a building panel 159, which is similar to the building panel 158 except that the building panel 159 is only 150 mm wide.



FIG. 3(

The external surface of the side portion 92 of the first footing 90a is joined to the base portion 91 of the second footing 90b, with the base portion 91 of the first footing 90a aligned with the side portion 92 of the second footing 90b. This results in the channels 94 of the footings 90a and 90b being oriented perpendicular to each other.



FIG. 3(
o) shows a straight 180° joiner 100b which also comprises a pair of the footings 90a and 90b but joined at a 180° angle. The base portions 91 of the footing 90a and 90b are joined to each other, with the respective side portions 92 and 93 being aligned. This results in the channels 94 of the footings 90a and 90b being aligned and facing opposing directions.

This results in the channels 94 of the footings 90a and 90b being oriented at 135° relative to each other.


The formation of a wall and a floor slab for a building structure using the building panels 50, footings 90 and joiners 100 will now be described with reference to FIGS. 4 to 10. The steps in forming a building structure using the present building system and method will be described later below with reference to FIGS. 12 to 18.



FIG. 4 shows a first building panel 50a being mounted to a first footing 90a as a first step in building a wall 300 for a building structure 400 according to a preferred embodiment of the present invention. The base portion 91 of the footing 90a is mounted to a concrete floor slab or ground via any suitable means such as by suitable RAMSET™ (registered) fasteners. A lower end 55 of the building panel 50a is inserted into the channel 94 of the mounted footing 90a, with the planar surface 58 being adjacent the first side portion 92.


If desired, the building panel 50 can be attached to the side portion 92 via any suitable fastener means such as spot welding or using a TOG-L-LOC™ (registered) machine.



FIG. 5 shows the building panel 50a mounted to the footing 90a. FIG. 5 also shows a second footing 90b, a second panel 50b, reinforcement mesh 170, and a brace assembly 180.


The second footing 90b is mounted to the floor slab parallel to and spaced from the first footing 90a, with the first side portions 92 parallel and facing each other and having a distance of 60 mm therebetween.


The second panel 50b is shown in the drawing spaced from the first panel 50a for illustration purposes only. The second panel 50b in actual use is attached to the first panel 50a using the 180° joiner 100b with the channels 94 of the joiner 10b receiving the upper end 55 of the first panel 50a and the lower end 55 of the panel 50b. The first and second panels 50a and 50b are attached to the joiner 100b also using suitable fasteners such as spot welding or a TOG-L-LOC® machine.


The building panels 50a and 50b are supported by the brace assembly 180 which comprises an anchor 182 mounted to the floor slab spaced from the first footing 90a, and lower and upper brace struts 184a and 184b respectively attached to the first and second building panels 50a and 50b.


The anchor 182 is typically mounted at a distance of between 200 cm to 400 cm from the first footing 90a. The anchor 182 comprises a first short bracket 200a which is essentially a 90° bent plate having two sides 202 and 204 which are perpendicular to each other. Both sides 202 and 204 include a respective aperture 203 and 205 therein. The anchor 182 is mounted to the floor slab via a fastener inserted through the aperture 203. This positions the other side 204 vertically and first ends of the brace struts 184 are mounted to the side 204 via a threaded rod inserted through the aperture 205 and through apertures in the ends of the brace struts 184. The brace struts can be of any suitable material such as a hollow rod.


The lower brace strut 184a is attached to the first building panel 50a via a threaded rod 190 inserted into one of its central apertures 78a and another short bracket 200b. The threaded rod 190 is inserted into one of the apertures 78a and into the aperture 203 of the short bracket 200b and locked thereto via a nut. The orientation of the side 204 can thus be varied as required, and can be horizontally or vertically oriented. The side 204 is vertically oriented in the embodiment and attached to the lower brace strut 184a via a suitable fastener such as a nut and bolt inserted through the aperture 205 and an aperture at the end of the brace strut 184a.


The upper brace strut 184b is attached to the second building panel 50b also via another threaded rod 190 inserted into one of its central apertures 78a, two short brackets 200c and 200d and a long bracket 210.


The long bracket 210 is essentially similar to the short bracket 200, except that has laterally longer sides 212 and 214 and does not have the apertures 203 and 205. The threaded rod 190 is inserted into one of the apertures 78a the second building panel 50a and into the aperture 203 of the short bracket 200c. The side 204 of the short bracket 200c is oriented horizontally and supports one side 212 of the long bracket 210 with the other side 214 thereof engaging the band portions 64 of the formations 60. The other short bracket 200d is then disposed on top of the side 212 with its side 204 extending vertically, and the threaded rod 190 inserted into its aperture 203 and the three brackets 200c, 210 and 200d locked thereto via a nut. The upper brace strut 184b is then secured via a nut and bolt inserted through the aperture 205 of the short bracket 200d and into an aperture at the end of the upper brace strut 184b.


In actual use, further building panels 50 can be joined laterally to the wall 300 by adding further footings 90 aligned with the footings 90a and 90b. The long bracket 210 will then extend across at least two adjacent building panels 50 for supporting same.


The reinforcement mesh 170 is disposed to be between facing planar surfaces 58 of facing building panels 50. In use, another building panel 50 is mounted to the second footing 90b and will face the building panel 50a. The reinforcement mesh 170 is spaced from the planar surfaces 58 of both building panels 50 via suitable means such as bar chairs such that the reinforcement mesh 170 is disposed substantially halfway between the planar surface 58.



FIG. 6 shows the addition of third and fourth building panels 50c and 50d. the building panel 50c is mounted to the second footing 90b and the fourth building panel 50d is mounted to the third building panel 50c via a joiner 100b. The reinforcement mesh 170 is omitted for illustration purposes only but will be disposed between the building panels 50.


The third and fourth building panels 50c and 50d are supported to the first and second building panels 50a and 50b respectively via the respective threaded rods 190 which attach the first and second building panels 50a and 50b to the brace assembly 180. A respective spacer (not shown) such as a tube piece is received by the threaded rod 190 and disposed between the respective pair of planar surfaces 58 to engage against such surfaces 58 and maintain their spacing. The threaded rod is then inserted into one of the central apertures 78a of the third and fourth building panels 50c and 50d and locked via a nut.


Alternatively or additionally, the third and fourth building panels 50c and 50d are supported to the first and second building panels 50a and 50b via additional threaded rods 190 and spacers inserted through the side apertures 78b.


The spaced building panels 50 define a cavity 215 therebetween within which the reinforcement mesh 170 is disposed.



FIGS. 7 and 8 show the addition of a horizontal building panel 50e to the upper end 55 of the building panel 50b via a 90° joiner 100a. The channels 94 of the joiner 100a receive the respective ends 55 of the building panels 50b and 50e which are thus oriented perpendicularly to each other. The building panel 50e can be supported by any suitable structure such as scaffolding.



FIG. 9 illustratively shows the result of the first step in pouring concrete into the channel 215 between the building panels 50. The reinforcement mesh 170 and the connection rods 190 are embedded within the poured concrete 225. This forms a wall 300 having a composite structure comprising the building panels 50 on both sides with concrete 225 and the reinforcement mesh 170 therebetween.



FIG. 10 illustratively shows the result of the next step in pouring concrete on top of the horizontal building panel 50e to form an elevated concrete slab 226. Concrete is poured as required to achieve the desired thickness of the concrete floor slab 226. This forms an elevated floor 305 having a composite structure comprising the building panels 50 on a lower side with concrete slab 226 on top.


The elevated floor 305 can then be used as the base for additional floors of the building structure 400 as described below.


As can be appreciated, FIGS. 9 and 10 are for illustratively showing only the basic concept of the preferred embodiment of the present invention, being the use of the building panels 50, footings 90, joiners 100, threaded rods 190 and reinforcement mesh 170 to form the formwork 390 for concrete for the building structure 400, for forming walls 300 and elevated floors 305. The formwork 390 becomes part of the composite wall 300 and elevated floor 305. The formwork 390 in actual use will include panel members sealing the gap between the lateral edges 56 as required as well as a further panel extending on top of the panel 50d for forming the floor slab 226 (See for example FIG. 28).



FIG. 11 illustratively shows a cross-section of the wall 300. Once the concrete 225 is set, cladding 410 can be applied to the outer work surfaces of the building panels 50, being the band portions 64.


The cladding 410 can be of any type to provide the required finish, such as Magnesium Oxide wallboards, plasterboard such as GYPROCK™, metal sheets, plywood, a brick wall and the like. Because of the formations 60, the cladding 410 will be spaced from the plate body 52 of the building panels 50 and will form cavities 230 therebetween.


Referring back to FIG. 10, it can be seen that the concrete 225 of the wall 300 and the concrete 226 of the elevated floor 305 will set together to form a generally monolithic structure. With a building structure comprising a ground floor slab, two spaced walls 300 and an elevated floor 305 extending between the spaced walls 300, the preferred embodiment essentially provides a strong box structure with numerous advantages.


The structure of the wall 300 and the elevated floor 305 provides many advantages including one or more of the following:


The composite structure comprising a reinforced concrete wall with the building panels provides a generally thin wall with superior strength compared to traditional wall structures such as those using wooden frames and a brick-veneer structure;


The concrete wall 225 is fireproof and the wall 300 has less fire burning materials;


The formations 60 provide a structure for the attachment of desired cladding, and the cladding is spaced from the concrete wall 225 thus providing an air gap insulation via the cavities 410; and


Services lines can be run through the readily available service line apertures 79 and within the cavities 410.


Further advantages of the present invention will be described and will be apparent from below.



FIGS. 12 to 18 illustratively show the steps in building a building structure 400 according to a preferred embodiment of the present invention.



FIG. 12 shows three spaced wall formwork 390a, 390b and 390c mounted on a ground floor slab 500 supported by footings 502. The formwork 390 is supported by respective brace assemblies 180. The side formwork 390a and 390c each include a respective panel 50f extending upwardly from the external top edges thereof



FIG. 13 shows the addition of the horizontal building panels 50e extending between the formwork 390. The building panels 50e are supported by scaffolding 504.



FIG. 14 shows concrete poured into the cavities 215 of the formwork 390 and over the building panels 50e to form the concrete 225 of the walls 300 and the concrete 226 of the elevated floor 305. As mentioned, this concrete sets in one piece to form a monolithic structure.



FIG. 15 shows a worker 512 standing on top of the elevated floor 305. The upwardly extending panels 50f provide instant fall protection for the worker 512. Additional building panels 50g can then be mounted to the elevated floor 305, as well as inclined building panels 50h for forming a pitched roof 302 of the building structure 400. The panels 50h are joined to the panels 50g using the 135° joiners 100d.



FIG. 16 shows the addition of further building panels 50h and building panels 50m. The building panels 50h complete the inner formwork structure for the roof 302 and the building panels 50m are spaced from the building panels 50h using threaded rods and spacers, forming a cavity 215 therebetween. These panels are supported by braces 506.


In forming the formwork for the building structure 400, any of the building panels 50 and 152 to 162 and joiners 100 can be used as required depending on the width requirements. The half-panels 157 to 159 for example can be used for the angled portions of the walls where one side may need to be cut and does not require the formations 60.



FIG. 17 shows the building structure 400 after concrete 227 is poured into the cavity 215 for the roof 302 and between the panels 50f and 50g to form the roof 302 and an upper level wall 430. The braces 506 are then removed.



FIG. 18 shows the finished building structure 400 with cladding 410 attached to the outer surfaces of the walls 300. The cladding can be a brick wall 415 attached to the building panels 50 via brick ties or any desired cladding panel 410.



FIG. 19(
a) shows a first alternative wall structure to that shown in FIG. 11. As described, any desired cladding or wall covering can be attached to the building panels 50. In this embodiment, one side is covered by a brick wall 415 while the other side is covered by cladding panel 410.



FIG. 19(
b) shows a second alternative wall structure. In this embodiment, one side is covered by a double brick wall 416. This structure can be used for strengthening existing double brick wall structures which may be required for older structures. The building panels on one side of the wall 300 are attached to the existing wall via brick ties 521, with the other building panels then mounted to the ground as required and concrete poured therebetween. This can also be used to provide a new external or internal look to such building structures as the other side of the wall 300 can be covered with cladding of the desired finish.



FIG. 19(
c) is similar to the structure of FIG. 19(b) except it is for a brick veneer wall 417. As above, this structure can be used for strengthening existing brick veneer wall structures and providing a new external look to such building structures with new cladding.



FIG. 19(
d) is similar to that shown in FIG. 19(b).



FIG. 19(
e) provides another alternative structure where the external building panels 50 are removed from the wall 300 after the concrete is set. This provides a strengthened double brick wall with a new external look.



FIG. 28 illustratively shows the formwork 390 and horizontal panels 50e as already referred to above.



FIG. 29 shows an example of a finished building structure 400 according to the preferred embodiment being a granny flat (secondary suite). In Australia, such granny flats can be constructed without requiring development approval if they cover less than 60 m2 footprint. The structure 400 is 10 meters wide and 6 meters in depth. If traditional building methods are used, such granny flat structures are limited to a single level as such traditional structures cannot provide sufficient support for upper levels. The structure of the walls and the elevated floor slab of the present embodiment however provides sufficient support for adding an additional floor level to such structures. As such, a two or more level structure can be erected using the same footprint.



FIG. 30 shows an alternative use of the building panels of the present invention as a bushfire (wildfire) shield. The planar surfaces 58 of the building panels 50 can be coated with a fire/heat resistant coating such as TEFLON™. In use, emergency services can erect a number of the building panels 50 with the coated planar surfaces 58 facing outwardly to the oncoming direction of the fire. In such cases, the building panels 50 are used to dissipate the heat around the structure to minimise or reduce the combustibility of the building structure.


Whilst preferred embodiments of the present invention have been described, it will be apparent to skilled persons that modifications can be made to the embodiments described. For example, the building panels 50 can be made to have curved planar surfaces 58 which will allow curved walls to be formed.


In other possible modifications, the planar surfaces 58 can include formations therein to assist with bonding or attachment to the concrete, such as stippling, a roughened surface, protrusions and projections.


Also, the building panels can be colour-coded for easy assembly. As shown in FIG. 28, internal vertical building panels can be blue, external building panels can be yellow and the horizontal building panels can be green which assists workers during assembly.



FIG. 31 shows a stair step building panel 700 and a stair side form panel 702. These panels are generally similar to the building panels 153 above. However, for the step panel 700, the side portions 62 extend at an inclined angle relative to the band portion 64 and the plate body 52. This results in the plate body 52 being at an inclined angle when the stair panel 700 is rested on one of its side portions 62.



FIG. 32 (a) to (j) show the steps in building stairs 710 using the building panels of FIG. 31. The steps are as follows:


A stair base 712 is formed.


Dowel bars 714 are set into the stair base 712.

Threaded bar connectors 190 are installed between the side form panels 702, in spaced pairs extending between the first side portions 92 of the connectors 90.


Stair reinforcing bars 716 are installed extending across the threaded bar connectors 190.


Stair panels 700 are installed between the connectors 90, with the plate bodies 52 facing the top of the stairs. A building panel 50 is also installed below and extending between the side form panels 702. The building panel 50 is retained in position by the dowel bars 714.


Concrete 720 is poured.


The side form panel 702 are then removed.


Shows finished stairs 710, with the stair panels 700 removed or covered with cladding.



FIG. 33 shows an end view of an internal partition building panel 800 with a reinforcing bar 812. This building panel comprises a body 802 which is generally corrugated, having spaced dovetail shaped channels 804 formed therein. Adjacent channels 804 face alternating sides of the body 802.


Each channel 804 is defined by side portions 806 and a band portion 808, with the side portion 806 of one channel 804 forming the side portion 806 of an adjacent channel 804 which faces the other direction. For each channel 804, the side portions diverge to the band portion 808 forming a dovetail channel shape.


The side portions 806 comprise apertures 807 formed therein for receiving reinforcement bars 812 which extend laterally across the building panel 800.



FIG. 35 (a) to (e) show the steps in building an internal partition 830 (FIG. 34) using the building panel of FIG. 33. The steps are as follows:


Top and bottom J-track footings 90 are mounted to the floor and ceiling of the building structure.


Internal partition building panel 800 is mounted to the footings 90.


Cavity spacers 822 are disposed in the channels 804. Each spacer 822 extends generally from the band portion 808 to the apertures 807. The cavity spacers 822 are preferably extruded polystyrene foam such as Styrofoam®. The spacers 822 are also dovetail shaped.


Reinforcing bars 824 are installed across the apertures 807 as required. Services 836 are run across the channels 804 as required.


The building panel 800 is rendered using Shotcrete method, Gunite® or Light weight foam concrete 828 to form the finished internal partition 830.



FIG. 36 shows an end view of an external render building panel 840 with a reinforcing bar 812. This building panel is similar to the building panel 800 and includes spaced dovetail shaped channels 804.



FIG. 38 (a) to (c) show the steps in building an external render 850 (FIG. 37) using the building panel of FIG. 36. The steps are as follows:


Top and bottom J-track footings 90 are mounted to the floor and ceiling of the building structure and external render building panel 840 is mounted to the footings 90. Alternatively, the external render building panel 840 is mounted to an external cladding or building panel.


Reinforcing bars 824 are installed across the apertures 807 as required.


The exposed side is rendered using Shotcrete method, Gunite® or Light weight foam concrete 828 to form the finished external render 850.
