COMPLETE SPECIFICATION STANDARD PATENT Invention Title: FASTENING NOGGINGS TO WALL STUDS S.i The following statement is a full description of this invention, including the best method of performing it known to the Applicant:- This invention relates to wall frames of the kind fabricated from a j plurality of elongate structural members, namely a substantially i horizontal floor plate, a substantially horizontal roof or ceiling plate spaced above the floor plate, a plurality of upright, spaced apart studs Sextending from plate to plate, and a plurality of spaced apart substantially horizontal noggings extending from each stud to its neighbouring stud or studs.
More particularly the invention relates to such frames for use in low rise buildings, for example one or two storey domestic dwellings, wherein the frames are relatively light!y loaded and the frame members may be cold roll-formed strips of light gauge sheet metal, for example galvanised steel.
2 In the construction of such buildings every effort is made to keep costs down. This extends not only to the materials of the wall frames but also to the labour involved in assembling and erecting the frames. A substantial part of the labour involved resides in the affixture of the many noggings to the studs.
Traditionally the noggings have been comparable to the studs in cross-sectional shape and size, if only to permit the noggings to be secured to the studs by conventional fasteners, such as self-tapping I screws or the like. This is so notwithstanding that the noggings are only io lightly loaded axially (that is in longitudinal tension or compression) by comparison with the other frame members, being called upon only to l .it control lateral movement of the studs, such as would lead to buckling .thereof, rather than to resist the main weight loads imposed on the frames. Indeed the greatest stresses likely to be imposed on the noggings throughout their life are bending stresses due to the weight of persons using them as ladders when working on the building before the 'a l walls are clad.
The present invention takes advantage of the relatively light axial loading on the noggings to save material by using a nogging having a cross-section which is smaller than that of the stid, and provides a clip for securing the nogging to the stud, whereby the nogging may be affixed to the stud simply and quickly without the need for skill on the part of the assembler.
According to a first aspect, the invention consists in the i^ combination of at least three studs, being two outside studs and an intermediate stud, each stud pierced by a pre-formed hole, a nogging having a cross-section which is smaller than that of the intermediate j&1 (i N 3 stud extending through said hole of the intermediate stud from one outside stud to the other, and a clip engaging the nogging and the intermediate stud so as to prevent longitudinal movement of the nogging relative to the intermediate stud.
According to a second aspect, the invention consists in a clip, for use in conjunction with a stud pierced by a pre-formed hole and a nogging extending through said hole, comprising a body, nogging 1 ~gripping means on said body such that said body may be moved to cause the gripping means to engage the nogging and thereafter resist lo longitudinal movement of the nogging relative to the clip, and anchoring I means on said body that are able to be inserted through said hole until the body abuts the stud when the gripping means are not engaged with the nogging, but are unable to be retracted from said hole when the gripping means are engaged with the nogging.
S' 15 According to a third aspect, the invention consists in a method of I:i securing a nogging to a stud comprising the steps of passing a part of the nogging through a hole in the stud, inserting the anchoring means of t a clip according the invention through said hole until the body of the clip abuts the. stud, and then moving the clip to cause its gripping means to engagethe nogging.
By way of example, an embodiment of the above described invention is described in more detail hereinafter with reference to the I accompanying drawings. 1 Figure 1 is a perspective view of a clip according to the invention.
Figure 2 is a side elevation of a nogging and stud secured jj I A *-Ttogether by the clip of figure 1, with the near flange of the stud cut away.
I 4 Figure 3 is a front elevation of the subject matter of figure 2.
Figure 4 is an inverted plan view of the subject matter of figure 2.
The illustrated embodiment comprises a generally channel sectioned wall stud 5 which may be cold roll-formed from a sheet metal strip, for example a strip of steel coated with zinc or an alloy of aluminium and zinc. The stud 5 comprises a web 6 with a longitudinally extending stiffening rib 7 formed therein and two flanges 8. In accordance with the invention, a hole 9, which in this instance is circular, provides a passage through the stud for a nogging. The hole 9 is o positioned in the floor of the rib 7. The illustrated stud 5 is the intermediate of at least three substantially upright, substantially parallel neighbouring studs forming a portion of a wall frame.
The illustrated embodiment further comprises a nogging 10, being generally channel sectioned and comprising a wave-sectioned web 11, two mutually converging flanges 12, and out-curved lip flanges 13. The nogging 10 extends through the hole of the intermediate stud from one outside neighbouring stud to the other.
The nogging 10 may also be cold roll-formed from an initially substantially flat, coated steel strip.
The illustrated embodiment still further comprises a nogging clip 14 comprising a flat body 15 having anchoring means at one end and nogging gripping means at its other end. m In this instance the anchoring means comprise a flange 16 A.L projecting perpendicularly from the body 15. The flange 16 is tk" p r a pe N1* h.
appreciably narrower than the body 15 so that shoulders 17 of the body 15 extend outwardly from each edge of the flange 16. The connection between the flange 16 and the body 15 is such that the flange 16 is spaced outboard of the shoulders 17 by an amount substantially equal to the metal thickness of the stud 5. Thus, as may be seen clearly in figure 2, the flange 16 may lie flatly against one side of the floor of the rib 7, while the edges of the shoulders 17 abut the other side thereof after the flange 16 has been passed through the hole 9 and the clip body 15 brought into a position where it is lo substantially normal to the stud t N Ct The nogging gripping means of the clip 14 comprise at least two co-planar tongues 18 and 20 respectively, and preferably a third such Stongue 19, projecting from the body 15. The included angle between the planes of the body and the tongues may be about 750. The edges 21 of the centre tongue 19 (see figure 1) and the inner edges 22 of the outer tongues 18 and 20 are inclined so that the spaces between the inner tongue and the outer tongues are generally wedge shaped.
However each of the edges 22 is formed with two bights 23 and 24 respectively in it.
The arrangement is such that when the nogging 10 has been positioned so as to extend through the holes 9 of the neighbouring wall studs 5 of a wall frame, a clip 14 may be applied at each stud by inserting the clip's flange 16 through the hole 9 until the shoulders 17 abut the stud. After the flange 16 has been so inserted, the clip body may be swung upwardly about the shoulder to stud contact line until the lip flanges 13 of the noggings are loosely ensconced in the more widely spaced bights 23. The position of the nogging may then be finally adjusted as may be needed and the clip tapped with a hammer to cause i S -IC L 6 the nogging lip flanges 13 to become ensconced in the more closely spaced bights 24 and firmly gripped between the centre tongue 19 and the outer tongue 18 or 20 as the case may be.
It will be appreciated that the cli. of the invention may differ considerably in detail from the preferred form shown in the drawings. In general the nogging gripping means, where relying on friction and/or some degree of interference fit as in the illustrated embodiment, will be varied to suit each particular nogging shape and size. It may be that the nogging is pierced by an opening adjacent each stud, in which event the S o 10 gripping means may comprise a projection on the clip body adapted to extend through that opening. In other cases the gripping means may comprise a sharp spike on the clip adapted to be driven through the |nogging by a hammer blow to the clip.
jLikewise the stud anchoring means may differ in design. In j 15 particular those means may comprise a hook formation on the clip's body, adapted to engage over the margin of the stud that surrounds the hole through which the nogging extends.
