DETAILED DESCRIPTION

[0020] FIGS. 1 and 2 illustrate a wall construction 10 having a number of concrete panels 12 mounted on a number of channel-shaped steel studs 14. The studs 14 are spaced apart from one another along the length of the wall construction. Each panel 12 has a rearwardly and downwardly extending tie member 16. The tie members 16 are incorporated into the structure of the concrete panels 12 and extend outwardly and rearwardly into the studs 14. The studs 14 are oriented so that the channels thereof face the concrete panels.

[0021] Further, in the studs 14 the tie members 16 engage with respective pin members 18 each of which extends laterally across the channel of a respective stud 14. In use, the studs 14 are filled with concrete after the panels 12 and the tie members 16 are in place.

[0022] Still further, the construction 10 includes a furring channel 20 which is disposed inwardly of a stud 14. The furring channel 20 is spaced apart from the stud 14 by one or more generally U shaped brackets 22. The brackets 22 may be made of the same material as the furring channel. The brackets 22 are in contact with the furring channel on one side and are connected to the stud 14 by screws. A furring channel 20 may be attached to each stud 14.

[0023] The lower end 28 of each stud 14 is, as shown, mounted on a concrete foundation member 24. Further, the concrete foundation member 24 has an end mounted on a concrete footing member 26. The foundation member 24 and the footing member 26 can be a one-piece member like the footing member 110 or can be formed as individual members as shown in FIG. 1.

[0024] As shown, the lower ends 28 of the studs 14 are each mounted to a substantially Z shaped bottom plate 30. The illustrated plate 30 is a homogeneous, one=piece member made from plate that is galvanized to resist corrosion.

[0025] Each stud 14 is attached to the plate 30 by mechanical fasteners or by welding. The plate 30 in turn is mechanically or chemically attached to an upper surface of the foundation member 24. The illustrated plate 30 is attached to the foundation member 24 by mechanical fasteners, namely masonry fasteners 31. The exposed ends of the fasteners 31 are disposed at least partially within the studs 14. In other embodiments the plate 30 is attached to the foundation member using chemical adhesives that fasten the members together by chemical bonds.

[0026] The bottom plate 30 includes an upright section or portion 32 which extends upwardly along an adjacent inner side of the stud 14, a central section or portion 34 which extends beneath the stud 14 and a lateral section or portion 36 remote from the portion 32 which extends downwardly in contact with the foundation member 24. The illustrated plate portions 32, 34, 36 are each flat and generally planar.

[0027] In use, it has been found that water may accumulate adjacent the lower end 28 of a stud 14. With the use of the bottom plate 30 as described herein there is a drainage channel along the bottom plate 30 from the upright portion 32, along the central portion 34 and then down the lateral section portion 36 to the footing member 26. Further, the lateral section portion 36 resists water from freely passing inward along the junction between the lower plate 30 and the lower stud end 28. This avoids a build-up of water at the lower end 28 of the stud, thus reducing the incidence of corrosion at this part of the wall construction.

[0028] In other possible embodiments, the one-piece bottom plate 30 is replaced by separate individual lower plates 30, the lower end of each stud being attached to a respective lower plate. Each individual lower plate has the same cross section as the plate 30 to avoid buildup of water. Each lower plate can be mechanically or chemically attached to the foundation member 24.

[0029] FIGS. 3 and 4 illustrate a second embodiment wall construction that utilizes a bottom plate 40 that is different from the bottom plate 30. Only the differences between the plate 30 and the plate 40 will be discussed. The plate 40 includes an upright section or portion 42, a central section or portion 44 which extends beneath the studs 14, and a lateral section or portion 46 similar to the lateral portion 36 of the plate 30.

[0030] The upright portion 42 is itself a Z shaped portion and includes a lower upright portion 42a, an intermediate central portion 42b, and an upper upright portion 42c. The lower upright portion 42a extends upwardly away from one side of the body central portion 44 and extends upwardly along adjacent inner sides of the studs 14. The central intermediate portion 42b extends from the upper end of the lower upright portion 42a away from the studs 14 and is substantially perpendicular to the stud vertical axes. The upper upright portion 42c extends from a side of the intermediate portion 42b away from the lower upright portion 42a and extends generally parallel with the lower upright portion 42a.

[0031] The lower upright portion 42a and the intermediate central portion 42b define a pocket or recess 44 adjacent to the lower ends of the studs 14 that enables threaded fasteners 46 to extend from the recess 44, through the upright portions 42a, and into the studs 14 for attaching the studs to the lower plate 40. The exposed heads of the fasteners 46 are disposed in the recess 44 as shown in FIG. 4.

[0032] FIG. 5 illustrates water (represented by the arrows in the drawing) draining from the lower plate 40 in a manner similar to that described for the lower plate 30. The water may be condensate that forms between the studs 14 and a conventional waterproof barrier 48 spaced from and facing the inner faces of the studs. The lower end of the barrier 48 extends to the lower plate 40 and is against the inner side of the upright portion 42c to be between the lower plate 40 and the studs.

[0033] Water flows down the barrier 48 to the lower plate 40, flows across the plate intermediate portion 42b, and then down the lower upright portion 42a. The lower upright portion 42a is located in a gap 50 between the panels 12 and the foundation member 24. The gap 50 receives the water from the lower plate 40. The lower-most panels 12 include weep holes 52 near the lower ends of the panels that fluidly communicate the gap 42 to the outside of the wall for drainage of the water from the wall construction 10. The illustrated weep holes 52 are quarter-inch diameter through holes spaced apart from one another about six feet (about two meters) along the wall.

[0034] The one-piece lower plate 40 may in other embodiments of the wall construction be replaced by individual lower plates 40 that each attach to a respective stud 14.

[0035] While one or more embodiments have been disclosed and described in detail, it is understood that this is capable of modification and that the scope of the disclosure is not limited to the precise details set forth but includes modifications obvious to a person of ordinary skill in possession of this disclosure, including (but not limited to) changes in material selection, size, operating ranges (temperature, volume, displacement, stroke length, concentration, and the like), environment of use, and also such changes and alterations as fall within the purview of the following claims.
