Definitions

  • a plurality of embedment teeth extend generally perpendicularly outwardly from the body of the anchor plate and are fixedly received in the first of the members to be joined by the connector.
  • a plurality of spaced engaging apertures are also provided through the anchor plate, and, while those apertures are positioned adjacent the first member, the material of which the first member is comprised is recessed, indented, or otherwise removed from behind these apertures.
  • a plurality of enbedment teeth also extend generally perpendicularly outwardly from the body of the bayonet plate and are fixedly received in the second of the members to be joined by the connector.
  • a plurality of bayonet teeth extend perpendicularly outwardly from the body of the bayonet plate oppositely of the embedment teeth. The bayonet teeth are spaced in conformity with the spacing of apertures into which they are interfittingly received. Full seating of the bayonet teeth through their corresponding apertures locks the anchor and bayonet plates, and thus the first and second members, together.
  • metal connector plates were devised by which structural wooden components couldbe strongly, yet economically, prefabricated and shipped to the building locus.
  • An example of such a connector plate can be found in my US. Patent No. 3,211,043.
  • such connector plates can be categorized as being either of the exterior or sandwich type.
  • An exterior type connector plate has teeth extending outwardly from only one side of the plate and is, therefore, used to connect structural members that are joined in abutting relation.
  • sandwich type connector plates have teeth extending oppositely outwardly from both sides thereof and are thus adapted for connecting structural members that are joined in overlapping relation.
  • the present invention employs at least one anchor plate which is preferably prefixed to one of the members to be joined and at least one interlocking bayonet plate which is preferably prefixed to the second of the members to be joined.
  • the bayonet and anchor plates may be lockingly interfitted with considerable facility on the job and yet impart not only the load distribution but also the strength incident to thetraditionally factory applied connector plates so successful in the prior art.
  • the anchor plate is affixed to the first of the members to be joined by suitable fastening means and presents a series of spaced apertures. That material of the first memher which lies behind the apertures in said anchor plate is at least partially recessed or removedif the member is wooden, or wood-like, the member may simply be indented.
  • the bayonet plate is aflixed to the second of the members to be joined, also by suitable fastening means, and presents a series of bayonet teeth intermeshingly lockable with the apertures in said anchor plate. Locking is preferably accomplished by having the span of each aperture substantially equal the width of at least that portion of the bayonet tooth lockingly interfitted therein.

  • the improved connector when used to join a plywood panel to dimensional lumber, as shown in FIGS. -14, effects a distribution of the stresses between the members joined thereby over a relatively large area. At the same time the connector increases the horizontal shear strength of the plywood by transferring stresses deeply into the panel.
  • a connector 10 embodying the concept of the present invention employs at least one anchor plate 11 prefixed to one of the members 12 to be joined thereby.
  • the anchor plate 11 is provided with a plurality of apertures 13 spaced longitudinally therealong.
  • At least one bayonet plate 14 is prefixed to the second of the members to be joined by connector 10, and the bayonet plate 14 is provided with a plurality of bayonet teeth 16 spaced longitudinally therealong so as to be interfittingly received in the apertures 13 of said anchor 4 plate 11.
  • the material of the member 12 behind the apertures 13 is preferably indented, as by punching. However, the nature of the material, for convenience in fabricating may dictate that the material behind the apertures be removed, as by drilling or, if the apertures are aligned, even by kerfing.
  • the bayonet teeth 16 can be lockingly seated within the apertures 13 upon the application of as little as one-tenth the pressure required to seat teeth of the same configuration within the wooden member 12 itself.
  • This greatly reduced pressure can easily be applied with the members in situ at the construction site by a vibratory compactor 18, as represented schematically in FIG. 1.
  • the vibration imparted to both members 12 and 15 being joined in situ by the compactor 18 has been found not to be deleterious to the interlocking of the anchor and bayonet plates 11 and 14 of the improved connector 10 with the material at least partially recessed behind apertures 13. However, if the material is not recessed, the vibration of members 12 and 15 effectively prevents entry of the teeth into the wooden member 12.
  • the member 12 represents a plywood panel to be attached to one or more wooden dimensional members 15.
  • the anchor plate 11 for such use is preferably a strip of 1622 gauge metal from which a plurality of embedment teeth 19 are struck, or punched, preferably in opposed pairs from a single opening 20.
  • the embedment teeth 19 constitute the means by which the anchor plate 11 is prefixed to the plywood panel 12.
  • Each tooth 19 has a thickness substantially equal to the'thickness of anchor plate 11 because it was struck therefrom, and each tooth has a base portion 21 the side edges 22 and 23 of which are generally parallel and extend substantially perpendicularly outwardly from the body portion 24 of the anchor plate 11.
  • Each tooth 19 also has a tip portion 25 of lesser width than the base portion 21 which is formed integrally outwardly thereof with one edge 22A being preferably a continuation of edge 22 on base portion 21.
  • the opposite edge 26 of the tip portion 25 is preferably parallel to edges 22 and 22A but is spaced more closely thereto than the corresponding edge 23 of the base portion 21.
  • the edges 26 and 23 are joined by an inclined transitional shoulder 28.
  • the preferred proportions for this type embedment tooth 19 can also best be seen from FIGS. 2-4.
  • the width of the base portion 21 is approximately one-third /3) the length of the tooth 19, and the length, or extent, of the base portion, including the transitional shoulder 28 which is itself approximately one-sixth /6) the length of the tooth 19, measured perpendicularly outwardly from the body portion 24, is approximately one-half /2) the length of the tooth.
  • the width of the tip portion 25 is approximately one-half 0/2) the width of the base portion 21.
  • a tooth 19 three-eighths /8) of an inch long has been found most adequate for prefixing an anchor plate 11 to three-quarter A) inch plywood 12.
  • the base portion 21 would be approximately one-eighth A3) of an inch wide by three-sixteeths 7 of an inch long, of which the transitional shoulder 28 would extend for approximately one-sixteenth A of an inch.
  • the width of the tip portion would also be approximately one-sixteenth of an inch.
  • the die not only crimps, or dishes, each tooth so that the outer surface 30 of the base portion 21 tends to be arcuate but also forms each tooth with a rearward arching about its base portion 21 so that the tip portion 25 is inclined away from the opening from which the tooth was struck in the direction of their longtiudinal alignment (FIG. 7).
  • the anchor plate 11 With these teeth embedded in the plywood panel 12, the anchor plate 11 is securely prefixed thereto.
  • the plurality of longitudinally spaced apertures 13 are aligned in two rows 31 and 32, one row on each side of the two rows 28 and 29 of openings 20.
  • each aperture 13 may be of circular configuration although other workers in the art may select other configurations after acquiring knowledge of the present concept. In any event it is necessary to the facile on-the-job joinder of anchor and bayonet plates that at least a portion of the wood behind apertures 13 be recessed. As best shown in FIG. 3, a plurality of cavities 27 aligned in two rows 33 and 34 may be punched into the surface of the plywood panel 12 before the anchor plate 11 is fixed thereto.
  • the rows 33 and 34 of cavities 27 lie coincident to the rows 31 and 32 and are of a depth and width commensurate with the particular bayonet tooth employed, as more fully hereinafter described. Equally satisfactorily, particularly with materials other than wood, the cavities may be provided by drilling or kerfing.
  • the bayonet plate 14 may be prefixed thereto by embedment teeth 35 which are of exactly the same configuration as the embedment teeth 19 on anchor plate 11.
  • the bayonet teeth 16 are longitudinally aligned in rows 38 and 39 (FIG. 6) which are laterally spaced a distance equal to the lateral spacing of the aperture rows 31 and 32. This allows for two rows 40 and 41 of embedment teeth 35 to be provided therebetween. Moreover, the same configuration which works so well for the embedment teeth also does superbly well as the bayonet teeth 16.
  • the bayonet teeth are thus also punched in opposed pairs from the same opening 20A with the bridge, or span, 42 between adjacent teeth of successive openings defining the dimension between correspondingly aligned apertures 13.
  • the base portion, or at least the edges 22 and 23 thereof having contact with the boundary wall 45 of the aperture does have some thicknessan amount equal to the thickness of the body 46 of the bayonet plate 14 from which it was struck.
  • the bayonet tooth 16 must be force-fitted into the aperture 13. With teeth of the dimension and configura- "tion shown this joinder force ay be readily applied by a hand operated compactor 18.
  • the interfitting of the bayonet teeth ad their corresponding apertures may be the sole means of locking the bayonet plate 14 to the anchor plate 11.
  • the kerfs 33 and 34 may, therefore, be of such width and depth as to provide no holding power againt extraction of the bayonet teeth.
  • the interlocking provided solely by this engagement of the teeth and their apertures provides a structural integrity between the plywood panel and the dimensional member to which it is joined such that the neutral axis of the load bearing member is not the neutral axis 48 (FIG. 1) of the dimensional member alone but rather the neutral axis 49 of the T-shaped section formed by the dimensional member 15 and the proximal portion 50 of the plywood panel 12.
  • the connector 10 for increased load carrying characteristics limited to the joinder of plywood to dimensional lumber.
  • a connector can also be used integrally to join pieces of dimensional lumber together; trusses can be connected to dimensional lumber or to plywood-all manner of structural connections being possible by varying the number of rows of embedment teeth and/ or bayonet teeth and connecting apertures.
  • FIGS. 1l13 One variation, particularly adaptable as an end, or edge, connector across a supporting member, is shown in FIGS. 1l13.
  • two panels 60 and 61 are abuttingly engaged and rest across a supporting member 62.
  • a bayonet plate 14 is prefixed to the supporting member 62 with the two rows 38 and 39 of bayonet teeth 16 extending outwardly therefrom.
  • a modified anchor plate 111 is attached to each panel 60 and 61 in proximity to the abutting edges 63 and 64 respectively.
  • Each anchor plate 111 has one row 65 of embedment teeth 119 and a row 66 of connecting aperture 113 parallel thereto.
  • the row 38 of bayonet teeth 16 interfit with the row 66 of apertures 113 on that anchor plate 111 fixed to panel 60 to connect that panel to the supporting member 62, and the row 39 of bayonet teeth 16 likewise lockingly interfits with the row 66 of apertures 113 on that anchor plate 111 fixed to panel 6 to connect that panel to the supporting member 62.
  • FIGS. 14-18 Another form of abutting connection embodying the present concept is shown in FIGS. 14-18.
  • This connector 210 employs a connector plate 211 with a single row 268 of alternate openings 220 and paired apertures 213.
  • the embedment teeth 219 struck from the openings 220' are preset into the edge 69 of a panel-like member 70.
  • the connector kerfing parallel to the row of apertures will not suffice inasmuch as that would remove the material into which the embedment teeth must be seated.
  • the material is preferably recessed from behind the apertures 213 by drilling, or punching, the cavities 227.
  • the bayonet plate 214 also has a single row 271 of openings 220, the teeth punched therefrom extending from alternate sides of the plate 214 from alternate openings.
