Definitions

  • the invention relates to a panel having a central web and complementary polysurfaced female respectively male lips adjoined respectively to opposite first and second web edges for interlocking with complementary male respectively female lips of adjacent panels.
  • Panels of this kind are primarily used for building purposes, particularly for roof and siding structures.
  • the female lip comprises, in sequence, an upwardly and outwardly extending first element, an outwardly extending second element, an outwardly and downwardly extending third element and an arcuate re-entrant terminal element.
  • the male lip of the known panel comprises, in sequence, an upwardly extending first leg, an inwardly and downwardly extending second leg, an upwardly extending third leg and an outwardly extending fourth leg.
  • the second and third legs of the male lip extend into the space enclosed by the third and terminal elements of the female lip, while the fourth leg contacts the second element from below.
  • the lips form interengaging hooks, which, however, do not provide a sufficiently rigid and stable connection between adjacent panels. In case of non-uniform loading of the panels, there is a risk of relative movement of the lips.
  • the joint according to US-A 2 019 379 is particularly suited for use in connecting the slats of a rolling metal curtain.
  • the male lip When used in wall or roof structures, the male lip may be partially disengaged from the female lip by loads applied at locations adjacent to the male lip. The possible partial disengagement precludes formation of a reliable weather-tight seal.
  • the joint according to US-A 3 127 962 avoids the partial disengagement problem by providing tightly nested cylindrically-shaped connecting members.
  • a lubricant must be applied to the contacting surfaces of the connecting members to facilitate interconnection.
  • the cylindrically-shaped connecting members have substantially identical girths and therefore appear to utilize more material than is actually necessary.
  • US-A 3 511 011 utilizes intricately formed male and female lips of single and double metal thickness, respectively.
  • the female lip is particularly subject to damage during packaging, shipment and erection. Such damage would interfere with the interconnection of the lips and the formation of a weather-tight seal.
  • the task to be performed by this invention is to provide a panel of the type described above in which the configuration of the lips results in a snap-fit effectively precluding vertical and lateral movement of either lip relative to the other due to non-uniform loading and permitting of the formation of a reliable weather-tight seal.
  • the invention performing this task is characterized in that the female lip includes, in sequence, relative to the first web edge an upwardly and inwardly extending first element, an upwardly and outwardly extending second element, an outwardly extending third element, an outwardly and downwardly extending fourth element, and a re-entrant terminal element, and that the male lip includes, relative to the second web edge an upwardly and outwardly extending first leg arranged to overlap the first element of an adjacent panel female lip, a re-entrant arcuate terminal leg disposed over and spaced from the central web, and arranged for engagement with the re-entrant terminal element of an adjacent panel female lip, the first leg and the terminal leg being joined by at least two distinct legs and intermediate thereof at least one arcuate bend, the arcuate bend residing at a level above the terminal leg and being arranged to engage with an interior surface of an adjacent panel female lip, the lips being configured for snap-fit engagement with the complementary lips of adjacent panels.
  • the polysurfaced female lip 34 comprises, in sequence and relative to the first web edge 32: an upwardly and inwardly extending first element 36, an upwardly and outwardly extending second element 37, an outwardly extending third element 38, an outwardly and downwardly extending fourth element 39, and a re-entrant arcuate terminal element 40.
  • a bead 49 of sealant material is applied to an interior surface of the female lip 34.
  • the bead 49 may be applied along any line in a region of the female lip 34 which includes the contiguous interior surfaces of the first through third elements 36, 37, 38; and preferably a region which includes the contiguous interior surfaces of the first and second elements 36, 37.
  • the bead 49 may, as illustrated in FIGURE 1. be applied at the juncture 48 of the second and third elements 37, 38.
  • the polysurfaced male lip 35 comprises relative to the second web edge 33: an upwardly and outwardly extending first leg 41. and laterally spaced therefrom a re-entrant arcuate terminal leg 42.
  • the terminal leg 42 is disposed over and spaced from the central web 31.
  • the first leg 41 and the terminal leg 42 are joined by at least two distinct legs, that is a second leg 43 and a third leg 44, and intermediate thereof at least one arcuate bend 45 which resides at a level above the terminal leg 42.
  • the lips 34, 35 are configured for snap-fit engagement with complementary lips of adjacent ones of the panel 30 to secure the central webs thereof in fixed angularly spaced-apart relation relative to each other.
  • the upper portion of the female lip 34 which is constituted by the second, third and fourth elements 37, 38, 39 is symmetrical about a vertical plane P extending normal to the third element 38 and longitudinally through the center of the female lip 34. Also, the second and fourth elements 37, 39 converge toward a line L which is spaced above the third element 38 and which resides in the plane P.
  • the symmetry of the upper portion provides a visual resemblance to stiffening ribs 46 (FIGURES 18, 19) formed in the central web 31 of a roof panel 68.
  • the upper portion of the male lip 35 constituted by the second and third legs 43, 44 and the arcuate bend 45 is unsymmetrical about the plane P. That is, the arcuate bend 45 is laterally offset from the plane P and is remote from the juncture 50 of the first and second legs 41, 43.
  • the second leg 43 will cooperate with the second and third elements 37, 38 of . the female lip 34 to provide a pocket 67 (FIGURE 7) for the bead 49 of sealant material.
  • the sheet metal panel 30 is roll formed from material having a selected girth.
  • the edge of the material corresponding to the re-entrant tip 53 of the terminal element 40 is the control edge. Should the material exceed the selected girth, the excess material appears in the male lip 35 as a run-out flange shown in dotted lines at 54. The run-out flange 54 will not interfere with the interconnection of the female and male lips 34, 35.
  • first element 36 and the first leg 41 are inclined in the same direction and at angles 47 and 51, respectively, relative to the plane P.
  • the angle 51 of the first leg 41 may be equal to but preferably is less than the angle 47 of the first element 36 so as to provide for roll forming tolerances.
  • the first element 36 and the first leg 41 constitute - in the joint 61 (FIGURE 7) - overlapping members which coact with the other elements and legs of the lips 34, 35 to resist vertical disengagement of either of the lips 34, 35 relative to the other lip 35, 34 when the adjacent panels 30A, 30B are subjected to non-uniform loading. That is, upward movement of the panel 30B is resisted, in part, by the overlapping first leg 41, whereas downward movement of the panel 30A is resisted, in part, by the underlapped first element 36.
  • the male lip 35 of one panel is configured to provide a snap-fit engagement with the female lip 34 of an adjacent panel.
  • the spatial relationship of certain of the elements and certain interior and exterior dimensions of the lips 34, 35 will be explained with reference to FIGURE 1.
  • the arcuate bend 45 acts as a cam element which forces the terminal leg 42 to slide relative to the fourth leg 39 as will hereinafter be described.
  • the female lip 34 has an interior width indicated at 55, that is the distance between the interior surface of the terminal element 40 and the interior surface of the juncture 56 of the first and second elements 36, 37.
  • the normal distance from the interior surface of the fourth element 39 to the interior surface of the first element 36 is represented by the dashed dimension line 57.
  • the male lip 35 has a maximum width indicated at 58, that is the distance between the exterior surfaces of the terminal leg 42 and the juncture 50.
  • the maximum width 58 of the male lip 35 is equal to or less than the maximum interior width 55 of the female lip 34.
  • the normal distance 57 of the female lip 34 is less than the maximum width 58 of the male lip 35.
  • the female lip 34 has a height of 38.1 millimeters, an interior width 55 of 36.8 millimeters, and a normal distance 57 of 33.0 millimeters.
  • the second and fourth elements 37, 39 have an angle of convergance 72 of about 53.1 angular degrees.
  • the male lip 35 has an overall height H of 38.1 millimeters and a maximum width 58 of 36.1 millimeters.
  • the first distinct leg 43 has an angle of inclination 73 of about 75.1 angular degrees relative to the plane P, and the second distinct leg 44 has an angle of inclination 74 of 37.1 angular degrees relative to the plane P.
  • FIGURES 2 through 7 The sequence of forming the present joint 61 (FIGURE 7) between two of the building panels 30A, 30B is illustrated in FIGURES 2 through 7.
  • a first panel 30A (FIGURE 2) is secured tq support members 59 (only one visible).
  • a second panel 30B is installed by hooking the female lip 34 thereof over the male lip 35 (FIGURE 2); and then moving the second panel 30B laterally (FIGURE 3) until the re-entrant terminal leg 42 engages the interior surfaces of the third and fourth elements 38, 39. It will be observed in FIGURES 2 and 3 that the juncture 60 between the first element 36 and the central web 31 B may engage and slide over the first distinct leg 43 during lateral movement of the second panel 30B.
  • the second panel 30B (FIGURE 3) is rotated in a clockwise direction about the male lip 35 until the arcuate bend 45 (FIGURE 4) engages the interior surface of the third element 38.
  • the first and third elements 36, 38 are spread apart by the juncture 50 and the terminal leg 42 of the male lip 35.
  • the normal distance 57 is increased, that is approaches the maximum width 58 of the male lip 35.
  • the first and third elements 36, 39 are spread apart such that the normal distance 57 equals that of the maximum width 58.
  • the female lip 34 and the male lip 35 are in line contact along three angularly spaced-apart lines indicated by the triangles; and are in surface contact between the terminal element 40 and the . terminal leg 42 along the arcuate region 75.
  • the three line contacts and the surface contact are maintained throughout the length of the joint 61.
  • the arrangement is such that the male and female lips 34, 35 are self-aligning and self- seating.
  • the bead 49 of sealant material must be so located within the female lip 34 that a weather-tight seal is assured.
  • the bead 49 may be applied, as illustrated in FIGURE 11, along any line residing substantially within a region 77 which includes the contiguous interior surfaces 81, 82 and 83 of the first through third elements 36-38. Specifically the region 77 extends approximately from the mid-line 79 of the first element 36 to the juncture 48 of the second element 37 with third element 38.
  • the bead 49 may be applied along any line residing substantially within a preferred region 78 which includes the contiguous interior surfaces 81 and 82. Specifically, the preferred region 78 extends approximately from the mid-line 79 of the first element 36 to the mid-line 80 of the second element 37.
  • the bead 49 of sealant material may be applied along the mid-line 79 of the first element 36 (FIGURE 12). As the panel 30B is rotated clockwise, the bead 49 engages the exterior surface 85 of the first distinct leg 43 (FIGURE 13) and is spread thereby along the interior surface 81 of the first element 36. It will be observed in the resulting joint 61' (FIGURE 14) that the sealant material 49 has been spread and is compressed between (a) the contiguous interior surfaces 81, 82 of the female lip elements 36, 37 and (b) the contiguous exterior surfaces 84, 85 of the male lip legs 41, 43.
  • the bead 49 of sealant material may also be applied along the mid-line 80 of the second element 37 (FIGURE 15). As the panel 30B is rotated clockwise, the bead 49 engages the exterior surface 85 of the first distinct leg 43 and is displaced thereby. It will be observed in the resulting joint 61" (FIGURE 17) that the sealant material is compressed between the interior surface 82 of the female lip element 37 and the exterior surface 85 of the male lip leg 43.
  • a weather-tight seal can be formed provided the bead 49 does not contact the arcuate bend 45 of the male lip 35. Such contact would cause a portion of the bead 49 to be displaced away from the cavity 67 (FIGURE 7); and the amount of sealant remaining would be insufficient to form an adequate weather-tight seal. Undesirable contact with the arcuate bend 45 can be prevented if the female lip 34 is engaged with and rotated about the male lip 35 in the manner illustrated in FIGURES 2 to 7.
  • the bead 49 preferably is provided along any line residing substantially within the preferred region 78 (FIGURE 11). It will be observed in FIGURES 12, 13 and 15, 16 that displacement of the bead 49 by the first distinct leg 43 is always toward the, subsequently formed cavity 67 (FIGURES 14, 17) and not away from the cavity 67.
  • FIGURES 8 through 10 Alternative arrangements of the present joint are illustrated in FIGURES 8 through 10. Corresponding numerals will be employed to identify corresponding parts heretofore described.
  • FIGURES 8 illustrates an arrangement wherein the first and second distinct legs 43', 44' of the male lip 35 are of substantially identical width and the arcuate bend 45 is centered on the plane P.
  • FIGURE 9 illustrates an arrangement wherein the first leg 41 and the terminal leg 42 of the male lip 35" are joined by three distinct legs 62, 63 and 64 and intermediate thereof two arcuate bends 65 and 66.
  • the first leg 41 and terminal leg 42 may be connected by a plurality of distinct legs and arcuate bends. However, to minimize the amount of girth required to form the lips, it is preferred that the first and terminal legs 41, 42 be connected by the two distinct legs 43, 44 and the single arcuate bend 45. It is also preferred that the arcuate bend 45 be offset from the plane P as illustrated in FIGURE 1 so as (a) to maximize the size of the sealant pocket 67 (FIGURE 7); (b) to preclude undesirable contact of the arcuate bend 45 with the bead 49 of sealant material during interengagement of the lips 34, 35; and (c) facilitate the above-described cam function of the arcuate bend 45.
  • the joint 61 secures the adjacent central webs 31A, 31B in coplanar relation. It should be evident that the angular relation of the central webs 31 A, 31 B may, as illustrated in FIGURE 10, be altered as required. The only requirement is that the normal distance 71 between the terminal leg 42 and the web 31A be sufficiently large to permit passage of the terminal element 40 during interengagement of the lips 34, 35 as illustrated in FIGURES 2 and 3.
  • FIGURE 18 illustrates a roof panel 68 presenting the upstanding polysurfaced female and male lips 34, 35 along the opposite edges of the central web 31.
  • the central web 31 may be provided with any suitable profile which enhances the structural and aesthetic characteristics of the roof panel 68.
  • the central web 31 is provided with spaced-apart ribs 46 - the upper portion of the female lip 34 having a visual resemblance to the upper portion of the ribs 46.
  • the roof panel 68 is adapted to span across plural support members, such as the purlins 69.
  • a plurality of the roof panels 68 may be assembled, as shown in FIGURE 19, in side-by-side relation wherein the joints 61 of this invention connect adjacent roof panels.
  • Each of the roofing panels 68 is secured to the purlins 69 by plural fasteners 70.
