DETAILED DESCRIPTION OF THE INVENTION

(7) The reference numeral 11 designates generally a modular building for use for yard storage. Such buildings are well known in the art. Representative buildings can be found in U.S. Pat. Nos. 9,032,670 and 9,151,068 assigned to the assignee of the present application. The general construction details disclosed in these two patents are fully incorporated herein by reference except as noted herein. Such buildings 11 include a roof 12, sidewalls 14 and a floor (not shown). Such buildings 11 may also include a hinged door 15 and a window 16. A window 16 can be in a door 15 or a sidewall 14. As shown in these two referenced patents, the buildings are made from interconnected panels such as roof panels 17, wall panels 18 and floor panels (not shown herein, but are shown in the referenced patents). The panels 17 and 18 are typically made by a molding process such as blow molding with hollow interiors and are made of a polymeric material as described above in the Background. The panels 17, 18 are preferably made of thermoplastic materials such as those listed in the Background above. Other molding methods, such as rotational molding, can be used, or separate sheets can be joined together at their peripheral edges, such as by heat sealing. The panels 17 and 18 are preferably hollow to reduce the use of material and to make the component parts lightweight. Adjacent panels 17 and adjacent panels 18 are suitably coupled together to form ceiling and sidewall structures. The panels 17, 18 have main panel portions 19, 22 respectively.

(8) The present invention will be described with a joint 20 between two adjacent sidewall panels 18. However, it is to be understood that the invention can be used at a joint 21 between two adjacent ceiling panels 17 if desired. A representative joint 20 is shown in FIGS. 2-3. Position descriptions like side, top and bottom used herein are used as if the panel or part is used in the assembled building 11 construction.

(9) FIG. 2 illustrates a first embodiment of two interconnected panels 18. The panels 18 are joined together at joint 20. In this embodiment, the joint 20 is a lap joint that has overlapping mechanically interlocking flanges 27 and 28. The flanges 27, 28 have interior surfaces 23, 24 and exterior surfaces 25, 26 respectively. The flanges 27, 28 have thickness less than the main panel portions 22. The flange 27 has a tongue 29 that has a transverse cross-sectional shape that is received in a groove 31 in the flange 28 and captured between two generally opposing end surfaces 32, 33 of the groove 31. The tongue 29 has generally opposing side edge surfaces 34, 35 that correspond in shape and orientation to the surfaces 32, 33. The flange 28 has a tongue 36 received within a groove 39 in the flange 27. This double tongue and groove arrangement forms a mechanical interlock to help resist relative lateral movement between adjacent panels 18. It also provides a tortuous path for water and wind to traverse before it can pass through the joint 20. The tongues 29, 36 extend along the length of adjacent panels 18. Likewise, the grooves 31, 39 also extend along the length of their respective panels 18. On a given panel 18, preferably its flange 27 has a tongue 29 while its flange 28 on the opposite side edge has a groove 31.

(10) As illustrated, means is provided at the exterior side edge 41 of a panel 18 to secure a reinforcing channel member 46 to a panel 18. It is to be understood that both side edges 41, 34 of a panel 18 could be provided with a reinforcing channel 46 or the channel can be secured to the panel 18 on the interior side edge 34. Preferably, at least part of the securement of the channel 46 is by mechanical interlocking between portions of the channel 46 and portions of a panel 18. As shown, the panel edge portion 41 having the groove 31 includes an edge bead 42 extending along its length. The bead 42 fits in the channel 39 of the flange 27. In the illustrated structure, the bead 42 includes a pair of outwardly opening and lengthwise extending channel grooves 43 with one groove on each side of the flange 28. A portion of the bead 42 extends laterally sideways away from the groove 43 (FIG. 6) and forms part of the side edge 41 of the flange 28. The bead 42 and grooves 43 preferable extend the full length of the panel 18, and the bead has a uniform exterior cross sectional shape along its length.

(11) The channel member 46 has an interior surface 51 that corresponds in size and shape to the exterior surface of the bead 42, FIG. 2. It is sized and shaped to be received over the outer portion of the bead 42 and has inwardly projecting longitudinally extending ribs 52, each of which are sized and shaped to be received in a respective channel groove 43. The channel member 46 is preferably continuous and has a length substantially equal to the length of a panel 18 extending between the top and bottom thereof. In its lateral cross-section, the channel member 46 has a pair of legs 53, with the leg 53 inside the joint 20 being an inside leg and the leg 53 on the outside of the joint 20 being an outside leg, each extending from a respective rib 52. A bight portion 54 is connected to and extends between the legs 53. Preferably, the outer surfaces of the legs 53 are flush to below flush with the adjacent surfaces of the flange 28 or the flange 27 if it has a channel member 46 mounted thereon. It is to be understood, however, that at least the outer surface of the inside leg 53 be flush or below flush. The channel member 46 can be held in place by frictional engagement between its interior surface and the exterior surface of the bead 42. A channel member 46 may be mounted on a respective bead 42 by sliding it longitudinally along the bead 42, or may be resiliently deformed and snapped over the bead until both ribs 52 are each in a respective groove 43. The channel 46 can also be suitably secured to the bead 42 with an adhesive if desired. The securement resists longitudinal movement of the channel member 46 relative to the panel 18 after it is installed. The channel member 46 can be roll formed, stamped or extruded if made of metal or metal alloy, herein referred to as metal. Suitable metals include aluminum, steel and the like. The wall thickness of the channel 46 can be on the order of 0.01 inches to about 0.06 inches. The outer surface of a channel member 46 is shaped similarly to the inner surface of the channel 46 to facilitate its formation. The channel member 46 can also be a molded plastic material or plastic with reinforcing filler. The channel member 46 can be a composite of metal and molded plastic if desired. A preferred material for the channel 46 is an aluminum alloy or galvanized or painted steel to provide resistance to corrosion.

(12) Adjacent panels 18 are secured together, preferably with mechanical fasteners. The flanges 27 and 28 are placed in overlying relationship to one another with the top edges and bottom edges of two adjacent panels being preferably aligned. During the formation of the panel 18 and hence the flange 27, as seen in FIG. 3, a plurality of threaded bores 58 are formed therein. Through openings 59 are provided in the flange 28 to receive a shank 61 of a fastener 60 therethrough. A preferred fastener 60 is commonly referred to as an easy bolt. The shank 61 has external threads that are received in internal threads within the bores 58 and, upon tightening of the fasteners 60, the flanges 27, 28 are brought together, securing two adjacent panels 18 with the flanges 27, 28 being in overlapping relationship. Preferably, a plurality of fasteners 60 are provided in spaced apart relationship along the length of the panel 18 to effect the joinder of adjacent panels 18.

(13) FIGS. 4, 5 show a second form of overlapping marginal flanges forming a lap joint. These flanges are designated generally 71, 72. The flanges 71, 72 do not use the double tongue and groove arrangement of the flanges 27, 28. Instead, they have generally planar abutting overlapping surfaces 73, 74 respectively. The bight 54 abuts a longitudinal side edge surface 76 and the side edge surface 78 of flange 71 abuts the side edge surface 80 of flange 72. The remainder of the structure of a panel 18, channel member 46 and bead 42 are the same or similar as described above.
