BRIEF DESCRIPTION OF DRAWINGS
Reference will now be made to the accompanying Figures which illustrate preferred embodiment(s) of the invention and in which:-
FIG 1 is a series of three view of a first embodiment of the invention;
FIG 2 is a series of three views of a second embodiment of the invention; and
FIG 3 is a series of two views showing both embodiments being employed in a wall frame.
BEST MODE
With reference firstly to FIG 1 there is shown a first embodiment of the invention in which a pair of like C-section members are connected.
A first C-section member 10 has the end portions 14 of its flanges crushed together such that the effective web dimension adjacent the end of the C-section member is reduced. Each end portion 14 of the flange is crushed inwardly by a dimension corresponding to the thickness of the material making up the flange. Each end portion 14 of the flange includes a drill hole 16 for receiving a fixing element as will be described later.
Referring now to the second C-section member 12, it will be noted that each flange of the C-section member 12 includes a return extending from the distal end of the flange and a portion of each return is cut away at 18. Again, drill holes 20 are provided to receive a fixing element as will be described later.
As shown in FIG 1 (B) the crushed end portions 14 of the flanges of C- section member 10 are inserted through the cutaway portions 18 of the returns of the second C-section member 12.
Thereafter, as shown in FIG 1 (C) a fixing element, such as a rivet 22, can be inserted to fix the C-section members 10, 12 together.
Referring now to FIG 2, there is shown a second embodiment of the present invention in which like C-section members 30, 32 are fixed together. In this second embodiment a first C-section member 30 has an end portion of its web cut away such that the end portions 34 of the flanges extend beyond the termination of the web. Likewise, the end portions of the returns are cut away so that the extending end portions 34 of the flanges are spaced and parallel. Each of the end portions 34 is drilled at 36 to receive a fixing element as will be described later.
A second C-section member 32 has its flanges crushed together at 38 to define a region of lesser effective web dimension. Again, the crushed flanges 38 are drilled at 40 to receive a fixing element as will be described later.
As shown in FIG 2(B) the projecting and spaced flanges 34 of the first C- section member 30 closely straddle the crushed flanges 38 of the second C- section member 32. A fixing element, such as rivet 42, can thereafter be located in place.
Referring to FIG 3 there is shown a conventional wall frame assembly consisting of top plate 50, stud 52, nogging 54 and bottom plate 56. As will be noted, the first embodiment, as illustrated in FIG 1 , is utilised in connecting the stud to the top plate and to the bottom plate, respectively. The second embodiment, as shown in FIG 2, is used in connecting the nogging to the stud.
The preferred embodiments of the present invention provide significant advantages over the prior art. Firstly, the manufacturer can roll a single sized C- section member. This is a significant advantage as the rolling machinery need never be reset to produce C-section members of different dimensions.
Subsequent to rolling into the C-section shape, each member can be cut away, crushed and/or drilled as necessary.
The present invention provides a wall frame or floor frame assembly, for example, in which the bottom plate, stud, nogging and top plate present an even planer surface for attachment of wall sheeting or the like. This is contrast to the prior art where, due to the fact that the various C-section members were of different dimensions, the flange of one C-section member would necessarily stand proud of the flange of an adjacent C-section member therefore providing an uneven or irregular surface to which wall sheeting would be attached.
It will, of course, be realised that the above has been given by way of illustrative example(s) of the invention. Any variations, modifications, or omissions, as would be apparent to persons skilled in the art, are deemed to fall within the broad scope of this invention.
