Press-fit fastener for a cavity wall system

FIELD OF THE INVENTION

The present invention concerns systems and methods relating to building construction.

More particularly, the present disclosure relates to a press-fit fastener for a cavity wall system.

BACKGROUND OF THE INVENTION

Cavity walls in the building construction industry have a large range of materials and methods of manufacturing them. Brick veneer uses timber, steel and brick ties to connect internal and external masonry walls. All brickwork in cavity wall construction has a volume of chasing in it for wiring and plumbing services to the new premises. Energy efficiency in the building construction industry is by law.

In some areas foil insulation is needed to be added to the cavity of double brick walls generating further cost in the materials and materials labour, and is difficult to install around brick ties and lintels. Due to the continuous additions of technology, new services and upgrades to existing premises, trades are finding it difficult to access desired points to install penetration for new services as it may be half a day of wages to install a single power point. In particular, the cavity column removes the services installation problem (chasing). With the introduction of the energy efficiency report it is also now necessary to install additional materials to single leaf stud walls, many with less desirable attributes to bolster up the thermal abilities producing costs up to double the price of the walls and producing difficulties in time for the introduction of new products at installation. The introduction of this method for constructing a vented cavity to new dwellings has all these difficult aspects dealt with.

It is against this background and the problems and difficulties associated that the present invention has been developed. The cavity column is comprised of two metal rolled steel studs, a standard building product that is manufactured worldwide and that is used for the construction of the internal leaf of the perimeter of the dwelling, which is a single stud wall frame in general home construction.

SUMMARY OF THE INVENTION

The press-fit fastener in this description replaces the nut and bolting method through compression reducing the time expended for the manufacture of a rigid connection. In this way we are able to achieve the necessary strength for the cavity system (a single rigid dual stud wall cavity column).

The invention relates to the fixing of two items similar to a nut and bolt fixture, two triangular

tapered rods with backward angled teeth both equal in all directions. The two triangular tapers, with self-aligning backward teeth, are pressed from either side through the desired materials, through the distance piece, until the backward raking teeth engage.

For the present invention disclosed, there is provided a method of forming a building construction walling system in the form of multiple prefabricated panels joined via a cavity column.

The method is comprised of first a metal rolled steel stud with rectangular holes punched centrally to receive a plurality of separation tubular distance pieces as to provide a space between and the press fit fastener.

The method also includes a second metal rolled steel stud with rectangular holes punched centrally but at an offset or minor step up to receive the plurality of tubular distance separation pieces and press-fit fasteners in an inverted position and a mirrored state.

BRIEF DESCRIPTION OF THE DRAWINGS

The above and other features will become more apparent from the following description with reference to the accompanying schematic drawings given as an example. The drawings are for the purpose of illustration only and are not intended to be in any way limiting, wherein: Figure 1 is a perspective view of a press fit fastener provided in a cavity column of a cavity wall system; Figure 2 is an exploded perspective view of the cavity column shown in Figure 1; Figure 3 is an enlarged view of the area indicated by arrow III in Figure 2, showing a

single press fit fastener; and Figure 4 is an assembled perspective view of the view shown in Figure 3.

DETAILED DESCRIPTION OF THE DRAWINGS

Referring to the drawings, there is shown a press fit faster and a cavity wall system according to the disclosure. There is also disclosed a method of forming a building construction walling system in the form of multiple prefabricated panels joined via a cavity column 10.

The cavity column 10 includes a first metal rolled steel stud 2b and a second metal rolled steel stud 4b. The first stud 2b includes multiple rectangular holes 2a punched centrally along the first stud 2b. Similarly, the second stud 4b includes multiple rectangular holes 4a punched centrally along the second stud 4b. The studs 2b and 4b are arranged to be joined together by a number of press fit fasteners 12, which include two opposing press fit fastener units la and 1b, and a distance piece 3. The second stud 4b can be at an offset or minor step up so that the holes 4a are slightly offset from the holes 2a.

The distance pieces 3 provide a space between the first stud 2b and the second stud 4b and to receive the press fit fastener pair 1.

Eachpress fit fastenerunit la and lb comprises a triangular tapered rod having backward angled teeth that are arranged to engage with the teeth of its opposing press fit fastener unit la, lb when the latter is in an inverted position and a mirrored state as shown in Figure 3.

The tubular distance piece 3 defines a channel for receiving the tapered rods of both the opposing press fit fastener units la, lb wherein the distance piece 3 is arranged to hold the tapered rods pressed laterally together to prevent the angled teeth of the opposing press fit fastener units la, lb from disengaging.

As has been discussed there are considered to be a number of preferred arrangements of the present invention that have advantages that can be applied to the building application.

It is to be appreciated that each of the embodiments have been specifically described and that the present invention is not to be construed as being limited to any specific feature or element

Australia - Patent Application Number 2018202596

of any one of the embodiments. Neither is the present invention to be construed as being limited to any feature of moulders of embodiments, or variations described in relation to the embodiments.

Also not to be misconstrued is that its only application is to the common cavity column. The press-fit fastener can be manufactured from metals, wood and plastics. Further, the press-fit fastener can be also used in other applications than building construction e.g. toys and furniture.

Claims
