building structure 50 by a plurality ofclips 30 and screws 44 as needed for the particular design. For example, theprefabricated wall panels prefabricated wall panel 10A vertically onto thebuilding structure 50. Aclip 30, including a base flange 32 (shown inFIG. 2 ), is used to clamp theprefabricated wall panels 10A to thebuilding structure 50. Theclip 30 is placed on theprefabricated wall panel 10A so that thebase flange 32 rests on thecheek surface 22 Thebase flange 32 includes a plurality of holes 40 (shown inFIG. 2 ) to enable theclip 30 to be fastened to thebuilding structure 50 withscrews 44. Accordingly, thescrews 44 are inserted through theholes 40 on theclip 30 and clamp theprefabricated wall panel 10A to thebuilding structure 50. - Once the
prefabricated wall panel 10A is coupled to thebuilding structure 50, theprefabricated wall panel 10B is slid horizontally into place so that thegroove 26 engages thetongue 24. In certain embodiments,non-skinning butyl caulk 46, or other sealant, may be applied to thetongue 24 and/or thegroove 26 before engagement thereof. Theprefabricated wall panel 10B covers theclip 30 and/or thescrews 44. - Referring to
FIGS. 2A and 2B , theclip 30 includes thebase flange 32 having on one edge a strip of metal that is bent to form arim 20. As used herein, a rim is a feature that facilitates the alignment of thebase flange 32 with theedge 36, but does not significantly increase the overall stiffness or strength of theclip 30. For example, a rim may increase the bending stiffness or strength of theclip 30 by less than 10 to 50%. The length of theclip 30 may be approximately 4.0 inches; the width of theclip 30 may be approximately 1.4 inches; the height of therim 20 may be approximately equal to 0.2 inch; and the angle between thebase flange 32 and therim 20 may be obtuse (e.g., approximately 100 degrees). Theclip 30 includes fiveholes 40 having a diameter of approximately 0.3 inch. Note that, in use, not all the holes may receive a screw. - A
clip 54 that allows for greater panel spans and/or provides improved wind resistance is illustrated inFIGS. 3A and 3B . Theclip 54 may be made of corrosion-resistant steel 14-gauge (approximately 0.07 inch thick), having a yield strength of at least 50 ksi. Theclip 54 includes aflange 38, aweb 42, abevel 56, and a plurality ofpre-punched holes 48. As used herein, a web also facilitates the alignment of thebase flange 32 with theedge 36. In contrast with a rim, a web significantly increases the overall stiffness or strength of theclip 30. For example, a rim may increase the bending stiffness or strength of theclip 30 by more than 50 to 100%. Theweb 42 and thebevel 56 are connected to theflange 38 at opposite edges of theflange 38. Theflange 38 is preferably flat. Theweb 42 and thebevel 56 are not located in the same plane as theflange 38; preferably, theweb 42 and thebevel 56 are located on opposite sides of theflange 38. The purpose of theweb 42 is to add bending strength to and stiffen theclip 54 and/or theflange 38. The purpose of thebevel 56 is similar to the purpose of theweb 42; it is to add bending strength and further stiffen theclip 54 and/or theflange 38. The length of theclip 54 is approximately at least 4.0 inches long, preferably approximately 8.0 inches, so it may be approximately the double of the length of theclip 30; the width of theclip 54 may be approximately 1.4 inches; the height of theweb 42 may be approximately equal to ¾ inch; the angle between theflange 38 and theweb 42 may be perpendicular (i.e., approximately 90 degrees); the length of thebevel 56 may be approximately 0.7 inch; and the angle between theflange 38 and thebevel 56 may be obtuse (e.g., approximately 135 degrees). Theweb 42 extends on only one side of the flange 38 (e.g., the inner side), and theflange 38 extends on only one side of the web 42 (e.g., the left side). Theclip 54 includes a minimum of threepre-punched holes 48 having a diameter of approximately 0.3 inch. - Another
clip 52 that allows for greater panel spans and/or provides improved wind resistance is illustrated inFIG. 4 . Theclip 52 may be made of corrosion-resistant steel 12-gauge (approximately 0.1 inch thick), having a yield strength of at least 50 ksi. Increasing the thickness of the clip may stiffen and/or strengthen the clip retaining the panel. The shape of theclip 52 differs from the shape of theclip 54 primarily by its length, which is approximately 12 inches. Increasing the length of the clip may also allow a better distribution of the loads retaining the panel. - The
clips 52 and/or 54 may be used similarly as theclip 30 shown inFIGS. 1, 2A, and 2B . - Referring to
FIG. 5 , theprefabricated wall panel 10A is clamped to thebuilding structure 50 using theclip 54 shown inFIGS. 3A, 3B , or theclip 52 shown inFIG. 4 and screws 44 (or other fasteners). When the flange of theclip 52 and/or 54 is in place on thecheek surface 22 formed on theprefabricated wall panel 10A, the web of theclip 52 and/or 54 extends inwardly toward thebuilding structure 50 and is adjacent to theedge surface 36 of theprefabricated wall panel 10A. The bevel of theclip 52 and/or 54 does not interfere with theshoulder surface 34 and/or thetongue 24 of theprefabricated wall panel 10A. - Another
clip 58 that allows for greater panel spans and/or provides improved wind resistance is illustrated inFIG. 6 . Theclip 58 may be made of corrosion-resistant steel 14-gauge (approximately 0.07 inch thick), having a yield strength of at least 50 ksi. The shape of theclip 58 differs from the shape of theclip 54 shown inFIGS. 3A and 3B primarily by the number of pre-punched holes. The spacing between the pre-punched holes may be the same as inFIGS. 3A and 3B . Increasing the number of holes (e.g., to 5 holes) may provide more flexibility to the installer regarding fastener placement. While only 3 screws may often be required, it may be easier to install three screws on a variety of substrates if they are spread out. For example, the 3 fasteners may be installed in the first, third, and fifth holes, that is, every other hole. The 3 fasteners may still be installed in the second, third, and fourth holes, that is, in consecutive holes. Also, increasing the number of holes (e.g., to 5 holes) may allow a better distribution of the loads applied by the screws. - Another
clip 60 that allows for greater panel spans and/or provides improved wind resistance is illustrated inFIG. 7 . Theclip 60 may be made of corrosion-resistant steel 12-gauge (approximately 0.10 inch thick), having a yield strength of at least 50 ksi. The shape of theclip 60 differs from the shape of theclip 54 shown inFIGS. 3A and 3B primarily by the number of pre-punched holes and by its length, which is approximately 12 inches. - The
clips 58 and/or 60 may also be used as shown inFIG. 5 . - In other embodiments, the clips may be 4 or 6 inches long.
