DETAILED DESCRIPTION
[0279] Each of the floating connections shown in
[0280] Shown in
[0281] Referring again to
[0282] In the embodiment described with respect to
[0283] Advantageously, owing to the screw 40 being headless, its being able to float with respect to the top plate 21 is assured, including when the screw 40 is driven so far that the trailing end 48 thereof is, or during service becomes, coincident with the lower surface of the top plate 21 or disposed within the passage formed through the top plate 21, as shown in
[0284] Advantageously, the floating connection not only is readily inspectable for determining whether the screw 40 has been sufficiently driven into the trimmer/bottom chord, but also permits the separation between the top plate and the bottom chord/trimmer to increase or decrease. The floating connection and the formation thereof provide improvements over earlier types of floating connection. A connection of one such earlier type, shown in
[0285] The fastener could, without departure from the present disclosure, instead comprise a screw 40′ configured with a head, as shown in
[0286] Also, without departure from the present disclosure, the screw 40/40′ could lack a reamer portion, whereby the threadless portion would lie immediately adjacent the threaded portion, especially if the threadless portion were to have a diameter slightly less than that of the shank of the threaded portion.
[0287] In an alternative embodiment of the present disclosure, the fastener 40/40′ is, instead of being driven upwardly through the top plate 21, whereby it is fixed in the trimmer or bottom chord overlying that top plate 21, driven downwardly, through the trimmer or bottom chord such that it becomes fixed in the top plate 21, whereby the hole/passage is instead formed in the trimmer/bottom chord and the trimmer/bottom chord can thus float up and down with respect to the fastener (which remains stationary owing to it being secured to the top plate 21). Such an embodiment might be invoked, for example, where a stud or other member obscures the top plate from below, precluding driving of the fastener upwardly through it, or where the trimmer or bottom chord is steel (and the wall member is timber).
[0288] That said, the driving of the fastener upwardly through the top plate 21, where possible, is particularly advantageous because of ease of installer access beneath the top pate 21 and ease of siting of the appropriateness of the degree to which the fastener has been driven (as described above). The upward driving of the fastener from below can also, particularly given that there is a common availability of extended-length screw tools, eliminate the need for the installer to use a ladder to install the screw(s) to form the each/connection embodying the present disclosure, perhaps even permitting installer to stand on the floor to install the screw(s).
[0289] The strength of the load transfer element defined by a given screw 40/40′ can be varied by varying the gauge of the screw. Also, the spacings of screws 40/40′, forming respective connections embodying the present disclosure, along the wall member can vary according to the degree of shear transfer required at particular positions along the wall member.
[0290] The formation of connections embodying the present disclosure as described above with reference to the drawings, advantageously, is far more rapid than formation of conventional connections, requires only a single part/element (defined by the fastener) to form the connection (there being no bracket and nails to this end), and is practically foolproof, given in particular that an appropriate degree of driving of the fastener can be visually determined, as described above, and that function of the connection is not compromised if the fastener is underdriven, as also described above.
[0291] Also, it is conceivable (though less common) that, without departure from the present disclosure, the structural member, from which horizontal loads are to be transferred into the wall or into which horizontal loads are to be transferred from the wall, will pass through the wall, in which case that member will be arranged below the top plate 21.
[0292] It is to be appreciated that, without departure from the present disclosure, the structural member, though commonly a roof truss member or trimmer, could be another member, e.g. a hanging beam, ceiling joist, ceiling batten, intermediate ceiling joist or floor truss. It is also to be appreciated that, without departure from the present disclosure, the wall member, though commonly a wall frame top plate, could likewise be another member, e.g. a lintel, stud or nog.

[0294] The jig 10 is bent or folded from a blank 100, shown in
[0295] The wall 11 defines a first locator, comprising the face 11A, which, owing to its thus engaging the member 1 lengthways, i.e. along an axis (on side face 1A) that is parallel to the length axis Ai of the member 1, precludes rotation of the jig 10 about an axis that lies on the side surface 1A and is parallel to the axis A.sub.3, and which, owing to its also thus engaging member 1 depthways, i.e. along an axis (likewise on side face 1A) that is parallel to the axis A.sub.3, precludes rotation of the jig 10 about an axis that lies on the side surface 1A and is parallel to the axis A.sub.1.
[0296] The wall 11 also defines a second locator, comprising the edge 11B, which, owing to its thus engaging the member 2 depthways, i.e. along an axis (on side face 2A) that is parallel to the axis A.sub.3, precludes rotation of the jig 10 about an axis that lies on the side surface 2A and is parallel to the length axis A.sub.2 of the member 2.
[0297] The wall 12 defines another locator, comprising face 12A, which, owing to its thus engaging the member 1 lengthways, i.e. along an axis (on bottom face 1B) that is parallel to the length axis Ai of the member 1, precludes rotation of the jig 10 about an axis that lies on the bottom surface 1B and is perpendicular to the axis A.sub.1, and which, owing to its also thus engaging member 1 widthways, i.e. along an axis (likewise on bottom face 1B) that is perpendicular to the axis A.sub.1, precludes rotation of the jig 10 about an axis that lies on the bottom surface 1B and is parallel to the axis A.sub.4.
[0298] The guide 13 comprises a first supporting wall 13A, defining a flat support face 13A1, which is perpendicular to each of walls 11, 12/faces 11A, 12A, and a second supporting wall 13B, defining a flat support face 13B1, which is perpendicular to each of walls 12, 13A/faces 12A, 13A1 and is parallel to wall 11/face 11A, the wall 13A projecting from the said lateral side of the wall 12 and the wall 13B projecting from a lateral side of the wall 13A. Referring to
[0299] The jig 10 includes a corner C1, at which wall 11 and wall 12 are interconnected, a corner C2, at which the wall 12 and guide 13/wall 13A are interconnected, and a corner C3, at which the wall 13A and wall 13B are interconnected.
[0300] Where the element E is the fastener 3 (as is typically preferable), it is driven, preferably uninterruptedly, not only into/within the first member 1 but also through that member and thence into/within (and possibly through) the second member 2 until fully home. The further driving of the element E/3, whereby it passes through the first member 1 and/or extends into/through the second member 2, can be guided by the guide 13 (correctly located)—and possibly also by the hole(s) thus formed by the element E/3—though could instead be guided solely by the hole(s) (possibly with the jig 10 removed).
[0301] Where the element E is instead a hole-forming tool, the driving thereof will comprise (i) driving it, while guided by the guide 13 of the correctly located jig 10, into/within the first member 1. The driving thereof may additionally comprise (ii) further driving it, guided by the jig 10 correctly positioned and/or by the hole created by (i), such that it passes through the member 1. Where the driving includes (ii), it may, additionally still, comprise (iii) still further driving it, guided by the jig 10 correctly positioned and/or by the hole created by (i)/(ii), into/within (and possibly through) the second member 2. The subsequent application of the connecting element 3 to the members 1, 2 can then be, advantageously, guided by the hole formed by (i) or (i) and (ii), or by either or each of holes formed by (i), (ii) and (iii).
[0302] The jig 10 is configured with markings 11X and 13X respectively, arranged to be visible by the user thereof when in use. In the embodiment described and illustrated, markings 11X are arranged on wall 11, and comprise an arrow 11Y pointing in the direction, from the wall 11, in which the second member 2 is to lie/the jig 10 is to be slid (along member 2) when wall 11/face 11A is received against surface 1A, for the jig 10 to be correctly located, and further comprise a reference 11Z to the structural component comprising the second member which the edge 11B is to abut when the jig 10 is correctly located, namely the word “truss”, the second member 2 in the example illustrated being a truss. In the embodiment described and illustrated, markings 13X are arranged on guide 13, more particularly on wall 13A thereof, and comprise an arrow 13Y pointing in the direction, from the wall 13A/guide 13, in which the first member 1 is to lie/the jig 10/edge 11B is to be moved/slid (along member 2/surface 2A) when wall 11/face 11A is received against surface 1A, for the jig 10 to be correctly located, and further comprise a reference 13Z to the structural component comprising the first member which the wall 12/face 12A is to abut when the jig 10 is correctly located, namely the word “top plate”, the first member 1 in the example illustrated being a top plate.
[0303] The blank 100, shown in
[0304] The blank 100, shown in
[0305] The blank 100 includes a junction J1, between portion 111 and portion 112/section 118, a junction J2, between portion 112/section 118 and portion 13A/section 119, and a junction J3, between portion 13A and portion 13B, at each of which junctions it is bendable/foldable to form corners C1, C2 and C3 respectively. The junctions J1, J2 and J3 be configured therealong with score lines and/or perforations 116 to facilitate bending/folding.
[0306] The blank 100, specifically section 119 thereof, is configured with a void or notch 115, which opens through the opposed main faces and a lateral side of the section 119, defining an edge 115A which is transverse to junction J3 and at which the junction J3 terminates, whereby the section 119 is bendable/foldable at junction J3, such that that edge defines, between the corner C3 thus formed and said lateral side, an upper edge 15 of the wall 13B.
[0307] The dimensioning of the blank 100, referring to
[0308] length of wall 11, L.sub.11=103 mm
[0309] width of wall 11, W.sub.11=45 mm
[0310] length of wall 12, L.sub.12=57.5 mm
[0311] width of wall 12, W.sub.12=52 mm
[0312] length of wall 13A, L.sub.13A=82.5 mm
[0313] width of wall 13A, W.sub.13A=12.5 mm
[0314] length of wall 13B, L.sub.13B=67 mm
[0315] width of wall 13B, W.sub.13B=21.5 mm
[0316] width of each junction J, W.sub.J=1 mm
[0317] This dimensioning is such that, when the jig 10 is correctly located and the element E/fastener 3 is received against the walls 13A, 13B/faces 13A1, 131B, the longitudinal axis L of the fastener 3 is coaxial with the axis A.sub.3.
[0318] In another alternative embodiment, the truss bottom chord/trimmer and top plate could constitute the first and second members (instead of the second and first members) respectively. In such an embodiment, the jig would be dimensioned such that the locating face and locating edge of its horizontally locating wall are to be received against a side face of the bottom chord/trimmer and a side face of the top plate respectively, the face of the vertically locating wall is to be received against a top face of the bottom chord, and the guide is positioned such that, when the locating face and locating edge of the horizontally locating wall and the locating face of the vertically locating wall are so received, is above the top face of the bottom chord, to guide application of the connector/driving of the hole-forming tool through said top surface/into the trimmer/chord/top plate. In such an embodiment, appropriate dimensions for the jig (for a same-diameter fastener/connector, which connector would need to be longer, in order to be able to extend through the depth D.sub.2 of the chord/trimmer, across the gap between the chord/trimmer and the top plate, and into the top plate) would be as follows:
[0319] length of wall 11, L.sub.11=138 mm
[0320] width of wall 11, W.sub.11=45 mm
[0321] length of wall 12, L.sub.12=75 mm
[0322] width of wall 12, W.sub.12=24.5 mm
[0323] length of wall 13A, L.sub.13A=102 mm
[0324] width of wall 13A, W.sub.13A=12.5 mm
[0325] length of wall 13B, L.sub.13B=102 mm
[0326] width of wall 13B, W.sub.13B=21.5 mm
[0327] width of each junction J, W.sub.J=1 mm
[0328] Shown in
[0329] The jig 10′ is bent or folded from a blank 100′, shown in
[0330] The wall 11′ defines a first locator, comprising the edge 11B′, which, owing to its thus engaging the member 1 depthways, i.e. along an axis (on side face 1A) that is parallel to the axis A3, precludes rotation of the jig 10′ about an axis that lies on the side surface 1A and is parallel to the length axis Ai of the member 1.
[0331] The wall 11′ defines a second locator, comprising the face 11A′, which, owing to its thus engaging the member 2 lengthways, i.e. along an axis (on side face 2A) that is parallel to the length axis A.sub.2 of the member 2, precludes rotation of the jig 10′ about an axis that lies on the side surface 2A and is parallel to the axis A.sub.3, and which, owing to its also thus engaging member 2 depthways, i.e. along an axis (likewise on side face 2A) that is parallel to the axis A.sub.3, precludes rotation of the jig 10′ about an axis that lies on the side surface 2A and is parallel to the axis A.sub.2.
[0332] The wall 12′ defines another locator, comprising face 12A′, which, owing to its thus engaging the member 1 lengthways, i.e. along an axis (on bottom face 1B) that is parallel to the length axis Ai of the member 1, precludes rotation of the jig 10′ about an axis that lies on the bottom surface 16 and is perpendicular to the axis Ai, and which, owing to its also thus engaging member 1 widthways, i.e. along an axis (likewise on bottom face 1B) that is perpendicular to the axis A.sub.1, precludes rotation of the jig 10′ about an axis that lies on the bottom surface 16 and is parallel to the axis At
[0333] The guide 13′ comprises a first supporting wall 13A′, defining a flat support face 13A1′, which is parallel to wall 11′/face 11A′ and perpendicular walls 12′/face 12A′, and a second supporting wall 13B′, defining a flat support face 13B1′, which is perpendicular to each of walls 11′, 12′, 13A′/faces 11A′, 12A′, 13A1′, the wall 13A′ projecting from the said other end of the wall 12′ and the wall 13B′ projecting from a lateral side of the wall 13A′. The walls 13A′, 13B′/faces 13A1′, 13B1′ are arranged for receipt thereagainst of side portions of the element to be guided by the guide 13′, such that (when the jig 10′ is correctly located) the central longitudinal axis L of the element E is coaxial with the axis A3, whereby driving of the element, while the abutment between it and each of the faces 13A1′ and 13B1′ is maintained, directs it along the axis A.sub.3, through surface 1B, and into/within the first member 1. The wall 13A′ is configured with a tapered edge 13A2′.
[0334] The jig 10′ includes a corner C1, at which wall 11′ and wall 12′ are interconnected, a corner C2′, at which the wall 12′ and guide 13′/wall 13A′ are interconnected, and a corner C3′, at which the wall 13A′ and wall 13B′ are interconnected.
[0335] Where the element E is the fastener 3 (as is typically preferable), it is driven, preferably uninterruptedly, not only into/within the first member 1 but also through that member and thence into/within (and possibly through) the second member 2 until fully home. The further driving of the element E/3, whereby it passes through the first member 1 and/or extends into/through the second member 2, can be guided by the guide 13′ (correctly located)—and possibly also by the hole(s) thus formed by the element E/3—though could instead be guided solely by the hole(s) (possibly with the jig 10′ removed).
[0336] Where the element E is the fastener 3 (as is typically preferable), it is driven, preferably uninterruptedly, not only into/within the first member 1 but also through that member and thence into/within (and possibly through) the second member 2 until fully home. The further driving of the element E/3, whereby it passes through the first member 1 and/or extends into/through the second member 2, can be guided by the guide 13′ (correctly located)—and possibly also by the hole(s) thus formed by the element E/3—though could instead be guided solely by the hole(s) (once/where deep enough to guide the element E/3).
[0337] Where the element E is instead a hole-forming tool, the driving thereof will comprise (i) driving it, while guided by the guide 13′ of the correctly located jig 10′, into/within the first member 1. The driving thereof may additionally comprise (ii) further driving it, guided by the jig 10′ correctly positioned and/or by the hole created by (i), such that it passes through the member 1. Where the driving includes (ii), it may, additionally still, comprise (iii) still further driving it, guided by the jig 10′ correctly positioned and/or by the hole created by (i)/(ii), into/within (and possibly through) the second member 2. The subsequent application of the connecting element 3 to the members 1, 2 can then be, advantageously, guided by the hole formed by (i) or (i) and (ii), or by either or each of holes formed by (i), (ii) and (iii).
[0338] The jig 10′ may be configured with markings 11X and 13X as shown in the illustrations of the jig 10.
[0339] The blank 100′, shown in
[0340] The blank 100′ includes a junction J1′, between portion 111′ and portion 112′/section 118′, a junction J2′, between portion 112′/section 118′ and portion 13A′/section 119′, and a junction J3′, between portion 13A′ and portion 1313′, at each of which junctions it is bendable/foldable to form corners CI, C2′ and C3′ respectively. The junctions J1′, J2′ and J3′ be configured therealong with score lines and/or perforations 116′ to facilitate bending/folding.
[0341] The blank 100′, specifically section 119′ thereof, is configured with a void or cutout 115′ defining an edge 115A′ which is transverse to junction J3′ and at which the junction J3′ terminates, whereby the section 119′ is bendable/foldable at junction J3′, such that that edge defines both an upper edge 15A′ of the wall 13A′ and an upper edge 15B′ the wall 13B′.
[0342] The dimensioning of the blank 100′ is for a said first member 1 having a depth D.sub.1 of 35 mm (or instead, for example, 45 mm) and a width W.sub.1 of 70 mm, consistent with a standard timber section on-flat, and for a said second member 2 having a depth D.sub.2 of 90 mm (or instead, for example, 70 mm) and a width W.sub.2 of 35 mm, consistent with another standard timber section on-edge, and for the hole-forming element E/fastener 3 having a maximum diameter ϕ.sub.max (along its shank) of 8 mm. Referring to
[0343] length of wall 11′, L.sub.11′=134.8 mm
[0344] width of wall 11′, W.sub.11′=30 mm
[0345] length of wall 12′, L′=40 mm

[0350] width of wall 13B′, W.sub.13B′=7 mm
[0351] width of each junction J′, W.sub.j=1 mm
[0352] This dimensioning is such that, when the jig 10′ is correctly located and the element E/fastener 3 is received against the walls 13A, 13B/faces 13A1, 13B1, the longitudinal axis L of the fastener 3 is coaxial with the axis A.sub.3.

[0355] In another alternative embodiment, the truss bottom chord/trimmer and top plate could constitute the first and second members (instead of the second and first members) respectively. In such an embodiment, the jig would be dimensioned such that the locating face and locating edge of its horizontally locating wall are to be received against a side face of the bottom chord/trimmer and a side face of the top plate respectively, the face of the vertically locating wall is to be received against a top face of the bottom chord, and the guide is positioned such that, when the locating face and locating edge of the horizontally locating wall and the locating face of the vertically locating wall are so received, is above the top face of the bottom chord, to guide application of the connector/driving of the hole-forming tool through said top surface/into the trimmer/chord/top plate.

[0366] The jig 10 or 10′, though used for installation of a connector/fastener which provides a translationally floating connection between said first and second members in the example described and illustrated herein, is not limited to such installation. It could, for example, instead be used to install a connector/fastener which provides a connection that does not translationally float and/or applied to mutually transverse first and second structural members either or each of which is of another kind. In one alternative embodiment, the second member could be, for example, a trimmer (instead of a truss bottom chord) extending orthogonal to the first member.
[0367] Furthermore, where the jig 10 or 10′ is used for installation of a connector which does provide a translationally floating connection between said first and second members, the type of connector/floating connection formed may vary—for example the connector may be configured such that it is fixed to the first member and is translationally slidably/movably received in the second member (oppositely to that in the embodiments described and illustrated), or is translationally slidably/movably received in both members. Alternatively, the connector may be configured such that respective portions thereof are both fixed (at least axially) to the members in which they are received though can move one-relative-to-the-other along the axis A.sub.3—for example, it may have an extendable/retractable telescopic structure comprising the portions. That said, the connector described and illustrated provides for a particularly simple while highly reliable interconnection and installation.
[0368] Moreover, the axis A.sub.3 need not in all embodiments/applications be vertical/upright. It could instead, for example, be horizontal or assume an oblique orientation.
[0369] Although (as indicated previously), the truss bottom chord/trimmer and top plate could constitute the first and second members (instead of the second and first members) respectively, the jig 10 or 10′ and its being located for application of the fastener/connector from beneath, through the top plate will, in many applications, provide for the installer optimal access to the job, allowing the installer to be positioned, typically standing, beneath the top plate/truss to apply the fastener/connector—and also for an inspector to be able to inspect readily the adequacy of the connection by sighting, from below, the end of fastener/connector at the underside of the top plate.
[0370] Also, as will be clear from the foregoing, the jig 10 or 10′ can be put to advantageous use for forming, in the former or each of the first and second members, a hole—correctly positioned and centred on the axis A.sub.3—for receipt, subsequently, of the connector/fastener (the hole(s) serving to guide the connector/fastener, during application thereof, whereby it is correctly orientated and positioned in the connection.
[0371] In another embodiment of the present disclosure, the section 119/119′ could, instead of being configured with junction J3/J3′, have no such junction and be bent about an axis parallel to that junction, such that the guide defined thereby has a single curved face conforming to the curved exterior of the maximum diameter portion(s) of the fastener, or could be omitted altogether and replaced with a separately formed guide, e.g. a bush, appropriately supported from the rest of the jig. That said, the section 119/119′ and the configuration thereof described and illustrated, advantageously, provides a simple structure for ensuring reliable centring and guiding of the connector/fastener—and for a simple means of forming the structure (namely folding/bending at the junctions J2/J2′ and J3/J3′ to form 90° bends or folds, and thus the corners C2/C2′ and C3/C3′).
[0372] Shown in
[0373] The jig 10″, though being of single-piece or unitary construction (like jigs 10 and 10′), is moulded from plastic.
[0374] The jig 10″ comprises a horizontally locating wall 11″, a vertically locating wall 12″, transverse to wall 11″, and a guide 13″, projecting transverse to the wall 12″, in a direction opposite to that in which the wall 11″ projects. The wall 11″ defines on one side thereof a flat locating face 11A″ arranged to be (as also shown in
[0375] The wall 11″ defines the first locator, comprising the edge 11 B″, and the second locator, comprising the face 11A″. The wall 12″ defines the “other” locator, comprising face 12A″.
[0376] The jig 10″ or guide 13″ comprises, referring to
[0377] The walls 13A″, 13B″, 13C″/faces 13A1″, 13B1″, 13C1″ are arranged for receipt thereagainst of side portions of the element to be guided by the guide 13″, such that (when the jig 10″ is correctly located) the central longitudinal axis L of the element E is coaxial with the axis A.sub.3, whereby driving of the element, while the abutment between it and each of the faces 13A1″, 13B1″ and 13C1″ is maintained, directs it along the axis A.sub.3, through surface 1B, and into/within the first member 1.
[0378] The jig 10″ includes holders, designated generally by the reference numeral 14 (see
[0379] Referring to
[0380] The holders 14, referring to
[0381] Laterally inner edge portions of the projections 14A in each pair are preferably profiled to conform to, and be received against, the axially extending portion (i.e. curved in the example illustrated, owing to the axially extending portion they engage being circular in cross section).
[0382] The jig 10″ includes, referring to
[0383] As can be seen especially at
[0384] The jig 10″ is preloadable with a said element 3 whereby the element 3 is located to the guide 13, particularly such that the central axis L of the element 3 is coaxial with the guide axis and thus positioned for driving thereof. To this end, the holders 14 include a preloading holder 14.3 the opposed formations/projections 14A of which extend from the walls 13A″ and 130″, and may also extend from wall 13B″, and engage the unthreaded portion/shank 42 of the (preloaded element 3) when the latter is received therebetween, though not to such a degree that the friction between the portion/shank 42 and the projections 14A hinders sliding of the former/element 3 along the projections 14A/laterally opposed edges thereof when the element 3, supported by the guide 13″, is driven. The holder 14.3 can be considered to be additional to the guide 13″, and positioned at an end thereof which is rearward with respect of the direction of driving of the element 3, or to define the rearward end thereof.
[0385] The said pairs comprise ones in which the projections 14A together define a grip or clamp (which is, owing to the projections' being integrally formed with the portions of the jig 10″ from which they extend, and to the opening action thereof being attributable to elastic deformation, is a “living” clamp or grip) and/or (referring to
[0386] The jig 10″, referring to
[0387] Also formed on the wall 11″/16″ (on the opposite side thereof to the face 11A″) are a marking 11U″, comprising the words “extra screws”, to refer to the elements 3 held in the storage section 16, and a marking 11V″, comprising the word “driver”, to refer to the tool 15 held in the storage section, the markings 11 U″ and 11V″ being positioned so as to be adjacent the elements 3 and tool 15, respectively, when so held.
[0388] The jig 10″ includes side or peripheral wall/walling 17B, projecting from a periphery of the wall 17A, in the same direction as the wall(ing) 16B, stiffening the wall 17A and defining the edge 11B′. The jig 10″ further includes opposed tab or wall portions 18A and 18B, which project from wall 17A and are, as shown at
