Definitions

  • the present invention relates to building systems, constructional elements and methods of construction.
  • Building systems in the form of prefabricated modular building systems have a tendency to rely upon heavy machinery for their construction, are generally labour intensive requiring many different tradesmen and, although being modular, require the separate construction and application of external and internal finishes.
  • An example of components of a prefabricated modular building system is aluminium cladding. Such cladding is typically positioned and fixedly located on the exterior of a fibre panel or wood panel building structure.
  • Another example of modular elements for buildings includes a system comprising end posts and concrete slabs attached therebetween. These slabs may then be rendered or coated as necessary once the building is constructed.
  • a building system for securing a plurality of adjacent constructional elements to form a wall including:
  • At least two opposed posts positioned in use to define a space therebetween and adapted to secure respective ends of the elements, such that element ends are communicable with each other through the space.
  • the configuration of the invention allows for an improved and simplified system of construction. It also allows for improved location and interaction of utilities, such as electrical wiring, water supply via conduits, etc, from one constructional element to another through the space, and allows for the location and access of such utilities within a space within a constructional element.
  • utilities such as electrical wiring, water supply via conduits, etc
  • the system includes a base at which an end portion of each of the posts can be located.
  • the base includes an upstanding spacer on outer or inner sides of which the posts are mounted to define the space therebetween.
  • each post includes a central channel extending along at least part of its length, typically at least at its end portion.
  • the spacer includes a projection which is complementary to the central channel of the respective end portions of the posts.
  • the system allows the formation of two or more walls extending from the posts.
  • Such walls may be linearly aligned, orthogonal, or acute/obtuse to each other.
  • the system includes three posts allowing a junction of three walls extending therefrom. In another embodiment, the system includes four posts allowing a junction of four walls extending therefrom.

  • a constructional element having a front face and an opposed rear face, the element including:
  • cladding formed about the structural member such that, on the rear face of the constructional element, at least an end portion of the structural member is exposed.
  • Exposure of the structural element on the rear face of the constructional element allows the constructional element to be attached to a framework via the structural member, the framework including support elements.
  • It may be only an end portion of the structural member which is exposed to allow attachment of the structural element to a support element at its end, but preferably the structural member is exposed along the entire length of the rear face of the constructional element.
  • the rear face of the constructional element is substantially flat.
  • the structural member includes an internal cavity, which may be hollow or filled with an insulating material.
  • the structural member is a rectangular box section.

  • a preferred embodiment of the invention is a building system for securing a plurality of adjacent constructional members in the form of boards 10 in the form of a wall 12 .
  • the wall 12 may be a sidewall, floor, roof, ceiling, etc.
  • the building system may be employed for forming a single room, garden shed, retaining wall, garden feature wall, or multi-room/multi-level house, for example.
  • the building system may be used in combination with other building systems. For example, when building a multi-room dwelling, the building system of the present invention may be used to form external walls only, while a conventional building system may be used to form internal walls.
  • the board 10 is typically in the form described in PCT/AU01/01375, including a rectangular structural member in the form of an elongate hollow box core 14 , and cladding 16 about the core. Ends 18 of the core 14 of the board extend beyond respective ends 20 of the cladding 16 .
  • At least two opposed posts 22 are positioned in use to define a space 24 therebetween.
  • the opposed posts 22 are adapted to secure respective ends 18 of the boards 10 in the form of a wall and such that ends 18 of the boards 10 are communicable with each other through the space 24 .
  • one of the opposed posts 22 has been removed to reveal the space 24 between the posts 22 .
  • Utilities in the form of telecommunication and electrical wires 26 can be seen to pass through the space 24 from an end 28 of one board 30 to adjacent end 32 of a second board 34 . It is in this manner that ends 18 of the boards 10 are communicable with each other through the space 24 .
  • this communication is not limited to adjacent ends 18 of boards in series, such as boards 30 and 34 illustrated in FIG. 2, but that any one of the boards 10 within the space 24 may communicate through the space 24 with any other boards whose ends 18 are in the space 24 .
  • electrical wiring may run from a ceiling, and down through the space 24 and then through any one of the boards 10 whose ends 18 are in communication with the space 24 . This would allow, say, for a light in the ceiling to be easily wired and connected to a light switch on a board 10 .
  • Other examples of utilities which may be supplied through the boards 10 and the space 24 also include air conditioning (hot or cold), vacuum supply, gas supply and water.
  • the form of post used depends on the type of wall 12 or wall junction to be formed by the posts 22 .
  • the first type of post 22 is a straight post 36 , as illustrated in FIGS. 1, 2, 3 , 7 , 8 and 10 .
  • the second type of post 22 is a small angle post 38 , as illustrated in FIGS. 4 to 9 .
  • the third type of post 22 is a large angle post 40 , as illustrated in FIGS. 4 and 6.
  • the posts 22 are usually rolled or folded from 2-5 mm thick steel plate, though may be formed from other plate material and thicknesses, depending on the application.
  • the straight post 36 is employed with another straight post 36 to allow the formation of two walls 12 extending from the posts 36 , where the walls 12 are on a mutual plane.
  • two small angle posts 38 may be used in combination with a straight post 36 to form a junction of two walls on a mutual plane and a third wall extending perpendicularly from the two walls.
  • four small angle posts 38 may be used to form a junction of four walls extending from the posts 38 at right angles from each other.
  • one small angle posts 38 may be used in combination with one large angle post 40 to form a junction of two walls extending from the posts at right angles to each other.
  • other wall junctions may be formed, for example allowing walls to join at different angles with respect to each other.
  • the building system preferably includes a base 42 at which an end portion 44 of each of the posts 22 can be located.
  • the base includes a mounting plate 46 , for mounting to a foundation pillar 48 by attachment devices in the form of bolts 50 .
  • the base 42 includes an upstanding spacer 52 , the outer sides to which the posts 22 are mounted to define the space 24 between the posts 22 .
  • the spacer 52 is usually spot welded to the base plate 46 .
  • the spacer 52 usually includes a large portion 54 and one or more small portions 56 , depending on the type of wall junction it is used with. For example, when used in a junction of two perpendicular walls extending from a single large angle post 40 and a single small angle post 38 , as illustrated in FIG.
  • the spacer includes the large portion 54 with two small portions 56 disposed at 90° with respect to each other about the large portion 54 .

  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • The description in the Applicant's co-pending International Patent Application No. WO02/35026 is incorporated herein by reference. [0073]
  • Referring to the FIGS. [0074] 1 to 11 and 21, a preferred embodiment of the invention is a building system for securing a plurality of adjacent constructional members in the form of boards 10 in the form of a wall 12. The wall 12 may be a sidewall, floor, roof, ceiling, etc. The building system may be employed for forming a single room, garden shed, retaining wall, garden feature wall, or multi-room/multi-level house, for example. Also, the building system may be used in combination with other building systems. For example, when building a multi-room dwelling, the building system of the present invention may be used to form external walls only, while a conventional building system may be used to form internal walls.
  • The [0075] board 10 is typically in the form described in PCT/AU01/01375, including a rectangular structural member in the form of an elongate hollow box core 14, and cladding 16 about the core. Ends 18 of the core 14 of the board extend beyond respective ends 20 of the cladding 16.
  • At least two opposed posts [0076] 22 are positioned in use to define a space 24 therebetween. The opposed posts 22 are adapted to secure respective ends 18 of the boards 10 in the form of a wall and such that ends 18 of the boards 10 are communicable with each other through the space 24. For example, in FIG. 2 one of the opposed posts 22 has been removed to reveal the space 24 between the posts 22. Utilities in the form of telecommunication and electrical wires 26 can be seen to pass through the space 24 from an end 28 of one board 30 to adjacent end 32 of a second board 34. It is in this manner that ends 18 of the boards 10 are communicable with each other through the space 24.
  • These utilities may then be accessed, for example, through the [0077] cladding 16 of a board 10. For example, as illustrated in FIG. 7, an electrical point 35 is located on a board 10, the point 35 being in communication with the wiring 26 within the board 10.
  • Furthermore, it will be apparent to those skilled in the art that this communication is not limited to adjacent ends [0078] 18 of boards in series, such as boards 30 and 34 illustrated in FIG. 2, but that any one of the boards 10 within the space 24 may communicate through the space 24 with any other boards whose ends 18 are in the space 24. Also, if the building system is employed to form a multi-level house for example, electrical wiring may run from a ceiling, and down through the space 24 and then through any one of the boards 10 whose ends 18 are in communication with the space 24. This would allow, say, for a light in the ceiling to be easily wired and connected to a light switch on a board 10. Other examples of utilities which may be supplied through the boards 10 and the space 24 also include air conditioning (hot or cold), vacuum supply, gas supply and water.
  • In the preferred embodiment of the building system, there are three forms of the posts [0079] 22. The form of post used depends on the type of wall 12 or wall junction to be formed by the posts 22. The first type of post 22 is a straight post 36, as illustrated in FIGS. 1, 2, 3, 7, 8 and 10. The second type of post 22 is a small angle post 38, as illustrated in FIGS. 4 to 9. The third type of post 22 is a large angle post 40, as illustrated in FIGS. 4 and 6.
  • The posts [0080] 22 are usually rolled or folded from 2-5 mm thick steel plate, though may be formed from other plate material and thicknesses, depending on the application.
  • As illustrated for example in FIG. 1, the straight post [0081] 36 is employed with another straight post 36 to allow the formation of two walls 12 extending from the posts 36, where the walls 12 are on a mutual plane. As illustrated for example in FIG. 7, two small angle posts 38 may be used in combination with a straight post 36 to form a junction of two walls on a mutual plane and a third wall extending perpendicularly from the two walls. Alternatively, as illustrated for example in FIG. 9, four small angle posts 38 may be used to form a junction of four walls extending from the posts 38 at right angles from each other. Or, one small angle posts 38 may be used in combination with one large angle post 40 to form a junction of two walls extending from the posts at right angles to each other. In alternative embodiments of forms of the post (not shown), other wall junctions may be formed, for example allowing walls to join at different angles with respect to each other.
  • The building system preferably includes a base [0082] 42 at which an end portion 44 of each of the posts 22 can be located. As illustrated for example in FIG. 6, the base includes a mounting plate 46, for mounting to a foundation pillar 48 by attachment devices in the form of bolts 50. The base 42 includes an upstanding spacer 52, the outer sides to which the posts 22 are mounted to define the space 24 between the posts 22. The spacer 52 is usually spot welded to the base plate 46. The spacer 52 usually includes a large portion 54 and one or more small portions 56, depending on the type of wall junction it is used with. For example, when used in a junction of two perpendicular walls extending from a single large angle post 40 and a single small angle post 38, as illustrated in FIG. 6, the spacer includes the large portion 54 with two small portions 56 disposed at 90° with respect to each other about the large portion 54. Alternatively, when used in a junction of two walls in a mutual plane extending from a pair of opposed straight posts 36, as illustrated in FIG. 1, the spacer includes the large portion 54 with two small portions 56 disposed in line with the large portion 54. When used in a junction of three walls, two in a mutual plane, and the third wall extending perpendicularly therefrom, as illustrated in FIG. 7, the spacer includes the large portion 54 with three small portions 56, where two small portions 56 are disposed in line with the large portion 54, and the third small portion 56 is disposed at 90° with respect to the line between the other two small portions 56. Lastly, when used in a junction of four walls, as illustrated in FIG. 9, the spacer includes the large portion 54 with four small portions 56, disposed at 90° with respect to each other about the large portion 54. As illustrated in FIG. 6, the spacer may also be employed separate from the mounting plate 46 in a different location in the space 24 to aid in defining the space 24 along the length of the posts 22. For this reason, the spacer 52 is hollow so as not to interrupt communication through the space 24. In an alternative embodiment, the spacer only includes the large portion 54.
  • In another alternative embodiment of the invention, illustrated in FIG. 11, [0083] additional caps 57 a and 57 b are used to further secure the posts 22 about the spacer. The caps 57 a and 57 b are usually screw-attached to respective posts 22. In the embodiment of the caps 57 a and 57 b illustrated in FIG. 11, a separate base plate 46 is not required, as it is in two parts 46 a and 46 b, each part being integral with caps 57 a and 57 b respectively. In another form (not shown) the caps are separate to the base plate 46. When caps are employed, it is usually not necessary to use the small portions 56 of the spacer 52. Also, the use of caps 57 a and 57 b can replace spacer 52, with the caps then co-operatively functioning as the spacer.
  • Each post [0084] 22 includes a central channel 58, preferably along its entire length, though in alternative embodiments the channel may be along part of its post's length. The channel 58 both increases the rigidity of the posts 22 along their length and is complementary to the relative part of the spacer 52 to which the post 22 abuts in use.
  • In use, the building system may include [0085] load bearing beams 60 for supporting a preformed floor 61 or ceiling. Alternatively, the beams 60 may support a floor or ceiling formed from boards 10. The beams are usually c-section beams, though may be in other forms. As illustrated in FIG. 6, the beams 60 may extend either from the posts 22 or from another beam 60.
  • Alternatively, as illustrated in FIG. 10, the [0086] pillar 48, base 42 and end portions 44 of the posts 22 may be located below ground level, in a ground 65, the ground being either natural or in-filled. The floor 61 may then be laid on the ground, with the option of using an expansion joint 67 between the floor 61 and the posts 22 and boards 10.
  • The [0087] boards 10 are usually secured to the posts 22 by self-tapping screws 63. The core 14 of the boards 10 ideally has two internal ribs 62 along the length of the core 14 to define a utilities hollow 64 and two void hollows 66 within the core 14. As illustrated in FIG. 1, for example, utilities, such as electrical cabling are located in the utilities hollow 64. Since the boards 10 are secured to the posts 22 on a section of the core 14 corresponding to the void hollows 66, the potential for the screws to damage or obstruct installation of the utilities in the board 10 is removed. As will be appreciated by those skilled in the art, whereas having two internal ribs 62 within the core 14 is ideal, it is not essential to the working of the invention.
  • The part-formed walls illustrated in FIGS. 2 and 6 show how the [0088] boards 10 may be further clad by sheet cladding 68, covering the entire wall surface. Alternatively, each individual board 10 may have preformed secondary cladding 70, as illustrated in FIGS. 12 to 14. This is particularly useful when the board 10 is used to form an internal wall, where it is not necessary to singularly clad the structural member 14 in a heavy material, such as glass reinforced concrete (GRC) typically suited for an external wall having a surface exposed to natural elements such as sun, rain, etc. Therefore, when merely used to form an internal wall, the board 10 may be clad in primary cladding 72 of a lighter, less durable material such as polystyrene or wood-pulp based material, for example. This primary cladding may then be clad by secondary cladding 70 of GYPROC®, or another appropriate material such as GRC. This variation on board manufacture aids in reduction of weight and cost of the board 10. Furthermore, depending on the use of the board 10, it may only require secondary cladding 70 on one side, as illustrated in FIG. 12.
  • Alternatively, as illustrated in FIG. 15, the structural member may only be clad about three of its four sides, depending on the requirement for the end use of the [0089] board 10. Furthermore, as illustrated in FIGS. 16, 17 and 18, recesses 74 may be formed in the cladding to expose a portion of the structural member 14 for easier attachment thereto of a brace member 76. As illustrated in FIG. 17, the brace member 76 may be employed for connection of a board 10 mid-way along another board. For example, this may be necessary if a perpendicular wall is required at a location away from the posts 22.
  • FIGS. 19 and 20 illustrate an embodiment of the [0090] board 10 adapted for use as louvres. In this embodiment, the board 10 has abutment means in shiplap form 78. Louvre connection devices 80 are connected to ends 18 of respective boards 10 to allow a standard louvre operation, the connection devices 80 being rotatably mounted to posts by protrusions 82 on the connection devices 80. Movement arms 84 extend from the connection devices 80 for attachment to an operating arm (not shown) to allow manual opening and closing of the louvres.
  • Now that the preferred embodiments of the invention have been described, it will be apparent to those skilled in the art that the improved building system has at least the following advantages: [0091]
  • 1 It allows for easier access and deployment of utilities; [0092]
  • 2 The post configuration is lighter than present methods; and [0093]
  • 3 The post configuration is cheaper to manufacture than present methods. [0094]
  • FIGS. [0095] 22 to 29 illustrate embodiments of a building system for securing a plurality of constructional elements in the form of boards 10 to form a panel or wall. In the embodiments of FIGS. 22 to 28, each board 10 includes structural members in the form of two hollow closed section cores 101, which are covered on three faces of the board 10 by cladding 100. On the three fully clad faces of the board 10, the cladding 100 extends to the ends of the cores 101.
