Description

AN INSULATED WALL PANEL SYSTEM WITH CABLE SUPPORT

Field of the Invention

This invention relates to a new building system.

Background of the Invention

Any discussion of the background art throughout the specification should in no way be considered as an admission that such background art is prior art, nor that such background art is widely known or forms part of the common general knowledge in the field in Australia or worldwide.

All references, including any patents or patent applications, cited in this specification are 0 hereby incorporated by reference. No admission is made that any reference constitutes prior art. The discussion of the references states what their authors assert, and the applicants reserve the right to challenge the accuracy and pertinence of the cited documents. It will be clearly understood that, although a number of prior art publications are referred to herein, this reference does not constitute an admission that 5 any of these documents forms part of the common general knowledge in the art, in Australia.

Hitherto it has been very difficult in relation to insulated building panels for providing access in said panels for service such as electrical wiring or hot and cold water pipes, gas pipes or channels through which solar heated air may be passed or cold air as the 20 case may be. Use can be made of structural panels formed of ribbed structures of thermoplastic resin such as described in US Patent 3664906 or FR 2828132 but such structural panels are complicated in construction or expensive to manufacture. Alternatively it was necessary to provide insulation panels having an upper face which contained grooves or channels to facilitate in the evaporation of moisture through the 25 insulation channels to the outside atmosphere as described in US Patent 4492064.

Alternatively it was necessary to provide insulated panels containing a plurality of spaced projections forming a network of interconnected air channels which are complicated in construction and costly to produce as described in US Patent 5473847. Alternatively use could be made of channels formed from galvanised steel in insulated 30 panels as described in US Patent 5638651 or channels located on an upper surface of an insulation layer or core such as described in US Patents 4712349, 4677800,

2019206115 19 Jul 2019

4628650, 4586304, 4492064 and 5260525. However the location of these channels often makes it difficult to access services internally. Reference also may be made to US Patent 7797908 which described an insulated panel formed from metal components as separate pieces and where there were provided a series of fingers extending 5 therefrom. The two metal components could be attached together near tips of the fingers so that an alternative sequence of fingers and spaces through which spaces wires or pipes may be passed. However, again the panel was complicated in construction and expensive to manufacture.

JP 8312121 provides a wall assembly having an inner wall frame which is fixed to a 0 heat insulative outer wall panel and there is also provided an inner wall backing board formed from plaster. Electrical wiring or gas or water pipes are located in a space between the backing board, inner wall frame and heat insulative outer wall panel thereby avoiding the formation of holes in the heat insulative outer panel. Again however such wall assembly is complicated in construction.

US Patent 5771645 relates to cuts being made to insulation cores of panels in the form of elongate channels or slots which are made by a hot wire for the purpose of locating electrical wiring and pulling out foam strips through a hole in an outer facing of the panel. However this method is not only complicated but expensive in manufacture.

US Patent 3707165 refers to a wall unit having integrally formed surface panels and a 0 foam core which surrounds hot and cold water pipes and drain and vent piping along with electrical wiring. The foam is pumped into a hollow interior of the wall unit after initial attachment of the hot and cold water pipes and drain and vent piping and electrical wiring to the wall unit.

US Patent 3783563 refers to prefabricated building construction using panel and 25 connector modules which are elongate beams having longitudinally extending open channels adapted to receive complementary ribs on the edges of flat panel modules. The connector modules are provided with interior passageways constituting conduits for electrical wiring, heating water and waste facilities. These interior passageways were formed integrally into the connector modules and thus the connector modules were 30 expensive to manufacture.

US Patent 4777774 refers to extruded panel components joined together to form a building structure which are internally ribbed and may be partially or fully insulated.

2019206115 19 Jul 2019

Internal conduits in the panel components provide passageways for electrical wiring, plumbing and other required services or utilities. If fully insulated the foam material is injected into each panel component.

The practice of pumping or injecting foam material into a hollow interior of a panel as described in US Patents 4777774 and 3707165 was expensive and required initial attachment of wiring looms or pipes to an internal frame which could be time consuming and difficult in certain cases.

The use of one or more tensioning cables 103 greatly increases the stability of the beam 97 and its support when supported by support rods 14.

In the practice of the invention it is necessary to the manufacture of wall 12 shown in FIGS. 1 to 10 or wall or panel assembly 13A shown in FIGS. 10A to 10G that the following steps are followed:

(i) The panels 13 or 37A are laid down flat and a choice is made concerning support columns or tubes 9 or 9B which may have a round cross section, RHS or other suitable cross section shape. The location of such support columns is made in accordance with engineering requirements which may vary from location to location. This also applies to location of hollow passages or service passages 25 which is also chosen according to engineering requirements. It also is appropriate to utilise instead of support columns 9 or 9B and service passages 25 that adjacent panels 13 or 37A may be connected to each other by a rib-socket interaction accompanied by use of sealant. Sealant may also be used in regard to installation of support columns 9 or 9B.

(ii) The panels 13 or 37A are then located in bottom plate or channel 19 and a holding down system such as by use of columns 9 shown in FIGS. 1 to 10 or use of tubes 9B shown in FIGS. 10A to 10G is then employed wherein panels or 37A are retained within bottom plate by fasteners 19C and are also retained in top plate 18 or 18A by fasteners 19B. At this stage the location of the use of support columns 9 or tubes 9B is then chosen according to engineering requirements as well as the choice of service passages 25. In this 30 regard loadings are one element that has relevance to choice of locations of support columns 9 or tubes 9B. Service passages 25 are usually chosen within or internally of panels 13 or 37A and the use of support columns 9 or tubes 9B

2019206115 19 Jul 2019 are usually located at the junction of adjoining panels 13 or 37A. In one example one may have 3 service ducts at 300mm centres in relation to a panel of 1200mm width.

(iii) After service ducts 25 have been located wiring 68 and pipes 72 may then be located in service ducts 25 as shown in FIG. 18.

(iv) The formation of apertures 72 in panels 13 or 37A may then be carried out followed by insertion of frame 85 and plywood plate 86 and cover plate 87.
