DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0040] FIGS. 1 through 4 illustrate basic components of the modular assembly, which in the case of FIG. 3 has been assembled in a simple planar wall arrangement of four identical modules 1. As best seen in FIG. 1 each elongate module 1 has a length L (shown in FIG. 3) and a uniform generally rectangular cross-section. In order to interconnect with adjacent modules 1, each module 1 has at least one engagement surface 2 and at least one elongate groove 3 extending the length L of the module 1.

[0041] As shown in FIG. 2, adjacent modules 1 of the assembly are laterally linked together with their engagement surfaces 2 abutting each other. In the embodiment shown in FIGS. 1 through 4, a figure-8 shaped connector 4 is mounted in the groove 3 of each adjacent module 1 and expands between the modules 1. FIGS. 3 and 4 show a simple rectangular wall assembled of four identical modules 1 joined together with three figure-8 connectors 4 mounted in the grooves 3 of each adjacent module 1.

[0042] FIG. 1 also shows a solid groove filler strip 5 which is of complimentary shape to the groove 3 and fills in the space in the grooves 3 when the modules 1 are used to form concrete for example so thate the filler 5 prevents inflow of liquid concrete. FIG. 1 also shows a reveal module 6 which may be mounted to the primary module 1 in various locations to create architecturally interesting grooves or ribs as desired in a finished concrete surface.

[0043] In the embodiment shown in FIG. 1 the module 1 is adapted for manufacture in an aluminium extrusion process. The grooves 3 are disposed in the engagement surfaces 2 however it will understood that grooves 3 and engagement surfaces 3 can be separated if desired and need not be in the same vicinity. The figure-8 connector 4 has two ends 7 each adapted for sliding engagement within the grooves 3.

[0044] In the embodiment shown in FIGS. 25 through 27, the connectors may comprise a bracket 8 having a first end 9 that is adapt for sliding engagement in the groove 3 and a second end 10 having a slot opening 11. A wedge 12 is slidably engaged in the slot 11 of cooperating brackets 8 in order to secure adjacent modules 1 together. Also, in the embodiment shown in FIGS. 25 and 27, the groove filler strip 5 may comprise a thin walled strip as opposed to a solid strip that fills the entire groove 3.

[0045] The embodiment shown in FIG. 1 includes grooves 3 which are substantially cylindrical in internal surface and engagement surfaces 2 which are substantially planar. The module 1 illustrated has a rectangular cross-section and planar engagement surfaces 2 with grooves 3 in all four sides of the rectangular cross-section. However, any shape of cross-section with any number of engagement surfaces and grooves may be provided depending on the requirements of the specific application. For ease of understanding and in view of the general use of rectangular forms for building materials a rectangular shaped cross section has been adopted in this description and drawings. When used for concrete formwork, scaffolding, platforms or stages, stairs or temporarily building structures, a simple rectangular shape is often desirable and is easily adapted as a replacement for wood. For example, a substantially planar low bearing surface 13 can be used to contain concrete or provide a platform surface in various structures. Alternatively, the opposite load bearing surface 14 is provided with a trapezoidal cross section channel 15 which can be used to form ribs in formed concrete floors or floor surfaces as explained in detail below.

[0046] Further, in the embodiments shown in FIGS. 8 and 9, modules 1 can be connected together with an elongated figure-8 connector 4 together with an angular offset module 16 having two engagement surfaces that are disposed at an angle ‘&agr;’ relative to each other.

[0047] FIGS. 5, 6 and 7 show two modules 1 connected together with a figure-8 connector 4 in various different configurations to provide flat surfaces or ribbed surfaces on inside and outside corners of a concrete form for example.

[0048] Likewise, FIGS. 10, 11, 12, 13 and 14 show various configurations of concrete forms to create corners, ribs and different wall thickness for concrete form work utilizing identical modules 1 and connectors in accordance with the invention.

[0049] FIGS. 15, 16, 17 and 18 also illustrate various configurations of identical modules 1 with connectors to form columns of poured concrete in various shapes and cross-sectional areas. The modularity of the form work provides the advantage that various shapes and sizes can be created using identical re-useable modular components.

[0050] FIG. 20 shows an exploded view of formwork removed from the finished work showing the means by which a completely planar concrete wall surface and alternatively an opposite ridged wall surface can be formed. It will be understood by those skilled in the art that floor surfaces wall and other structural components may be formed in a like manner with or without ridges and with various thicknesses as desired.

[0051] FIGS. 21 and 22 show use of the modules 1 to pour the concrete wall of the building for example with a door opening 17 and window opening 18. The bottom portion of the form may have a footing portion of larger width.

[0052] FIGS. 23 and 24 show the example of forming the wall of concrete having a footing 19 where modules 1 are used to form a footing 19 as well as a wall portion 20. Angle iron brackets 21 supporting sections of modules 1 of various lengths can be adapted to form wall 20 and footings 19 of various shapes and configurations.

[0053] FIG. 29 is a perspective view of a single module 1 with end caps 22 at each end, and six holes 23 drilled through side walls to conduct fluid through threaded fittings 24 and hoses 25 for heating or cooling the module 1. When the modules 1 are used to construct concrete formwork for example, heating of concrete in the winter or cooling during summer can be carried out by circulating hot or cold liquid with pumps through the hoses 25 and chambers created in the module 1 between end caps 22. The same arrangement may be used to inject liquid foam that later cures for insulating or structural reinforcing functions.

[0054] Although the above description relates to a specific preferred embodiment as presently contemplated by the inventor, it will be understood that the invention in its broad aspect includes mechanical and functional equivalents of the elements described herein.
