Description
1015202530CA 02264127 1999-02-24PCT/AU97 /00541I JUL 1993CONNECTOR PLATE AND METHOD OF ASSEMBLYFIELD OF THE INVENTIONThis invention relates to the manufacture of wooden structures such as roof and ï¬oortrusses, where structural members such as webs and chords are attached by means ofmetal connector plates, consisting of plates from which have been struck a pattern ofprojecting teeth which are driven into the members to effect the joint. The inventionalso relates to connector plates for use in the manufacture of such members. Theinvention is particularly applicable to the location and attachment of webs to chords inthe manufacture of wooden roof trusses.BACKGROUND ARTVarious procedures are used in the assembly and ï¬xing of trusses. In one approach,the chords are laid out and connected, then the webs are positioned and stapled to thechords to maintain their position while connector plates are applied successively toeach side of each joint. The plates are driven home by pressing. The need for astapling operation at each joint adds to the assembly time, as does the positioning ofthe underneath plate, for example by the use of a jig or frame device, or bytemporarily locating the underneath plate by means of a hammer. The latter techniquehas the further disadvantage that teeth may be bent, reducing the quality of the joint.Attempts have been made to reduce the time involved in truss manufacture byattaching the connector plates to components of the truss prior to their assembly withthe other components. For example, International patent application No.PCT/F191/00104 describes an approach in which the plates for one side of the trussare preâattached to the webs, while the plates for the other side of the truss are pre-attached to the chords. Such a method is of limited usefulness.SUMMARY OF THE INVENTIONAMENDED SHEETIPEA/AU1015202530CA 02264127 1999-02-24PCT/AU97 /00541"I4JUL1Q98The present invention seeks to provide an alternative approach, which enables theplates for both sides of the joint to be pre-attached to each end of a web, while stillenabling the webs to be brought into position in the truss without difï¬culty, prior topressing of the joint.This is achieved by providing the nail plates with at least one, but preferably several,teeth of greater length than the remainder of the plate teeth, these longer teeth beinglocated only in the region of the plate which is to be attached to one of the jointmembers, preferably the web.In this way, plates can be attached to the web ends by pressing the plates into position,the press driving only the longer teeth into the web. The opposed ends of the teeth ofthe portion of each plate which extends beyond the end of the web will thus still beseparated by at least the thickness of the chord to which the web is to be attached, sothe web can be brought into position for fixing to the chord without these teeth foulingthe chord and thereby obstructing movement of the web.Of course, while it is preferred to preâattach the plates to the webs, they may insteadbe pre-attached in the same way to the chords at the correct joint positions and thewebs then brought into position with their ends between the projecting opposed pre-ï¬xed plates.It may be noted here that in U.S. patent 3,304,106 of Gerald M. McCorrnack there isdescribed a nail plate which is divided into a region having short teeth and a regionhaving longer teeth. In the McCormack patent, however, the short teeth have lowwithdrawal strength, so that the plate may be permanently fastened to the member bymeans of the longer teeth and removably fastened to the other member by the shortteeth, in order that the truss may be disassembled for transport and later reassembledon site. Because the short teeth are incapable of forming a permanent joint, nail holesare also provided and the ï¬nal joint is achieved by nailing through these holes.AMENDED SHEETIPEJâ-\IAU1015202530CA 02264127 1999-02-24PCT/AU97 100541*1-4JULl998A connector plate of the kind described by McCormack is distinguished from platesaccording to the present invention by the fact that the short teeth of McCormack aredesigned for low withdrawal resistance and are incapable of forming a permanentjoint, whereas in the case of the present invention the short teeth are of conventionalconnector plate design, and consequently have conventional withdrawal resistance andare capable of forming a permanent joint. In other words, McCorrnack achieves theability to disassemble the joint by having shorter than normal teeth over one half ofthe plate, whereas in the present invention the ability to pre-attach plates to one side ofthe joint is achieved by using in one half of the plate some teeth which are longer thannormal. The conventional teeth employed in the plate are, ipsofacto, capable offorming a satisfactory joint without additional means such as nailing. Such a jointwill be referred to herein as a permanent joint.The invention will be exempliï¬ed below in its application to roof trusses, but it is tobe understood that it is applicable to other structural assemblies of woodencomponents, such as ï¬oor trusses.The accompanying drawings illustrate, by way of example only, the application of theinvention to the manufacture of roof trusses.BRIEF DESCRIPTION OF THE DRAWINGSIn the drawings,Fig. 1 is a plan view of a connector plate according to a ï¬rst embodiment of thepresent invention;Fig. 2 is a side elevation of the connector plate of Fig. 1;Fig. 3 illustrates a connector plate pre-ï¬xed to a web;"l"â"T'~* Vâ. ''1'.-": 1ââhi.-.Iâ1a.iu..J âJ1 l....l..nll-""â AU1015202530CA 02264127 1999-02-24PCT/AU97 /005411 4 JUL 1998Fig. 4 illustrates a connector plate according to a second embodiment of the inventionpreï¬xed to a ï¬rst member; andFig. 5 illustrates the connector plate of Fig. 4 in a ï¬rst stage of temporary ï¬xing to asecond member.DESCRIPTION OF THE PREFERRED EMBODIMENTSAs shown in Figs. 1 and 2, the connector plate 10 is provided, in a conventionalmanner, with rows of teeth 11 struck out from the plate leaving apertures 12.The manner of formation and the pattern of these teeth may be of any suitable kind.At four locations on the left hand portion of the plate (as viewed in Figs. 1 and 2), alonger tooth 13 is formed by punching from a longer aperture 14. In this way, asillustrated in Fig. 3, a pair of the plates 10 may be attached to an end of a web 15 bydriving the longer teeth 13 into the web, but stopping short of the point where theshorter, conventional teeth 11 penetrate the web.The web can then be introduced with a rotational movement into a truss so that theopposed free ends of the pre-attached plates embrace the chord 16, shown in ghostoutline in Fig. 3, and the joint subsequently formed by pressing the plates in anyconventional manner.The plate 10 illustrated in Figs. 1 and 2 is provided with four long teeth 13, oneapproximately at each comer of the region of the plate to be engaged with the web.This is but one example of a suitable pattern of location of the longer teeth. Theymay, for example, all be located at the rear of the plate, or towards the middle, oralong one or both sides. The location of the longer teeth is entirely a matter of choice.Similarly, the number of longer teeth may be chosen to suit the convenience of theapplication to which the plate is to be put, and to enable efï¬cient production of theplates. While it is possible to use only one longer tooth, a greater number is preferredm-f1w'\1v~.--2--. pt, . ,../u\i'o:a'.3.n;1..â ~.;;i*â..,,;.._;.;IPEA/AU10152025CA 02264127 1999-02-24PCT/AU97 I00541â1!+âJULl998to give stability to the pre-ï¬xing of the plate. It is also preferred in the interests ofstability that longer teeth are located both at the rear and the forward parts of therelevant region of the plate.Connector plates according to the invention can be employed at joints between morethan two members, for example where two or three webs are connected to a chord atthe same location.Figs. 4 and 5 illustrate a fllI'thâ¬Iâ development of the invention, in which the secondportion of the plate is provided with a number of teeth the length of which isintermediate that of the longer teeth provided for the pre-ï¬xing of the first portion ofthe plate, and that of the conventional teeth 11.This plate enables the elimination of separate means, such as stapling, for thetemporary ï¬xing of the web 15 in its correct position in conjunction with the chord 16,prior to the pressing of the joint. The plates 10 (only one of which is shown here) arepre-ï¬xed to the web 15 by pressing them only by a distance which does not exceed thedifference between the length of the teeth 13 and the teeth 17. At this stage the teeth11 will be proud of the surface of the web, and the teeth 17 will not obstruct theengagement of the web with the chord, as the chord enters the space between theopposed free ends of the plates. The plates can then be engaged with the chords bydriving the intermediate teeth 17 into the chord, for example by means of a hammerblow, prior to the ï¬nal pressing of the joint.It will be understood that the principles disclosed in this speciï¬cation can be appliedto connector plates and connector plate joints in wooden structures in many waysother than those given by way of example.:~-v-.7.--â~. 4 » .. 1, :â-r.*..uu.....6.../.-._..' ~.,,.. ._ ,,zPE;r4.au â
