JOHN H. MAC LEOD 3,538,663 BUILDING WALL FIN UNIT John H. MacLeod, San Marino, Calif., assignor to H. H. Robertson Company, Pittsburgh, Pa., a corporation of Pennsylvania Filed July 1, 1968, Ser. No. 741,546 Int. Cl. E04f 19/02; E04c 2/38 US. Cl. 52-309 8 Claims ABSTRACT OF THE DISCLOSURE BACKGROUND OF THE INVENTION Field of the invention This invention relates to a fin unit, and more particularly to a fin unit adapted for erection with a building wall for service as an architectural column-like building feature element.
Description of the prior art Building wall fins are used extensively in new building structures. The wall fins project outwardly from the building exterior wall and serve as prominent feature elements. The wall fins interrupt the large expanse of essentially fiat wall areas and render these wall areas more attractive. The wall fins normally are non-load bearing elements.
In the past, the building wall fins have comprised precast concrete elements having a white appearance.
The use of pre-cast concrete wall fins has many disadvantages. The weight of pre-cast concrete wall fins is great. For example, a recently erected building has a plurality of 26 feet long, precast concrete wall fins having a weight per foot of length of fin of 770 pounds or a gross weight of 10 tons each. In a proposed building, the precast concrete wall fins would have a weight per foot of length of fin of 300 pounds. The great weight of the precast concrete wall fins adds considerably to the structural steel tonnage of the building frame and to the foundation cost. Additionally, complicated wall fin-to-spandrel beam connections are required and expensive erection procedures are necessary. The use of pre-cast concrete fins is not an efficient use of materials since the wall fins are non-load bearing elements.
SUMMARY OF THE INVENTION The principal object of this invention is to provide a building wall fin unit which is relatively light in weight and which may be produced in a variety of architectural configurations.
Another object of this invention is to provide a building wall fin which does not have the disadvantages of the prior art pre-cast concrete wall fins.
The present invention provides a building wall fin comprising a generally U-shaped outer shell having spaced-apart inboard longitudinal edges and a generally U-shaped inner shell having spaced-apart inboard longitudinal edges. The inner shell is secured in spaced-apart relation to the outer shell whereby a generally U-shaped cavity is defined by the two shells. A light-weight foamed insulating material is disposed between the inner shell and the outer shell for maintaining the inner shell and United States Patent ice the outer shell in the aforesaid spaced-apart relation. Bracket means having one end secured to the inner shell project at the other end away from the inboard longitudinal edges of the shells and adapt the building wall fin for erection to a building structural framework.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 illustrates a building 20 having exterior walls 22 and a roof 23. Each of the exterior walls 22 is provided with a plurality of building wall fin units 24. The wall fin units project outwardly from the exterior wall 22 and may, as shown in FIG. I, extend from ground level to the level of the roof 23. The Wall fin units 24 are prominent feature elements which interrupt the large expanse of fiat area which the exterior walls 22 would present in the absence of the wall fin units 24.
Referring to FIG. 2, the building wall fin unit 24 comprises generally U-shaped outer and inner shells 26, 28, respectively. The inner shell 28 is secured in spaced-apart relation to the outer shell 26 whereby a generally U- shaped cavity 30 is defined by the two shells 26, 28. A lightweight foamed insulating material 32 is disposed in the cavity 30 between the outer and inner shells 26, 28 for maintaining the outer and inner shells 26, 28 in the aforesaid spaced-apart relation. The building wall fin unit 24 is provided with a bracket means 33, such as structural angles 34 which are secured to the inner shell 28.
The outer shell 26 includes a base 36 and two legs 38 terminating in spaced-apart inboard longitudinal edges 40.
The inner shell 28 includes a base 42 and two legs 44 terminating in spaced-apart inboard longitudinal edges 46. The spaced-apart inboard longitudinal edges 40, 46 are secured together by suitable fastening means, such as fasteners '48.
In this embodiment of the building wall fin unit 24, the outer and inner shells 26, 28 are each formed from a single piece of material. The outer shell, being exposed, is preferably formed from an essentially maintenance free material, such as steel sheets coated with polyvinyl fluoride film, stainless steel, bronze, aluminum, porcelainenameled aluminum, and the like. The inner shell, being hidden from view, may be formed from any suitable 3 sheet metal material, such as aluminum, galvanized steel and the like.
The generally U-shaped cavity is preferably substantially entirely filled with the lightweight foamed insulating material 32. Lightweight foamed insulating materials suitable for use in the present invention includes those foamed-in-place thermal insulating materials which are produced from organic and inorganic constitutents and which have a density of less than about four pounds per cubic foot. The prefered lightweight foamed insulating material is polyurethane foam.
Referring to FIG. 3, the building wall fin unit 24 may, instead, be provided with bracket means 33, such as plate members which are secured to the inner shell 28 and having terminal mounting portions 52 which are usually coplanar.
In FIG. 4, there is shown a building wall fin unit 54 comprising generally U-shaped outer and inner shells 56, 58 secured together in spaced-apart relation to define a generally U-shaped cavity 30*. A lightweight foamed insulating material 32 is disposed within the cavity 30.
In this embodiment, the outer shell 56 is formed from plural metal sheets 60, 62 and 64 which are secured together by a recessed, non-exposed fastening means, such as seams 66. The inner shell 58 likewise is formed from plural metal sheets 68, 70 and 72 which are secured together by fasteners 74. The sheets 60, 64 of the outer shell 56 terminate in spaced-apart inboard longitudinal edges 40. The sheets 68, 72 of the inner sheel 58 likewise terminate in spaced-apart inboard longitudinal edges 46 which are engaged with the longitudinal edges 40 and secured thereto by fasteners 76.
As shown in FIG. 5, the building wall fin unit 24 can be erected by securing the angles 34 to one of the horizontal flanges 78 of a horizontal girt 80 by suitable fasteners 82.
As shown in FIG. 6, the building wall fiin units 49(54) can be erected by securing the terminal mounting portions 52 of the plate members 50 to a vertical web 84 of a horizontal girt 80 by suitable fasteners 86.
Referring again to 'FIG. 5, the building wall fin unit 24 includes a cap member 88 for at least one and preferably both of the open ends of the fin unit 24. The cap member 88 is disposed between the outer and inner shells 26, 28. The cap member 88 protects the lightweight foamed insulating material 32 against exposure to the weather.
As shown in FIG. 7, the cap member 88 may be adhesively secured to the outer and inner shells 26, 28 by a suitable adhesive '89, such as asphalts, epoxy adhesives, polyurethane sealants, et cetera.
Referring to FIG. 8, there is illustrated a butt joint between two building wall fin units 24A, 24B. The building wall fin units 24A, 24B are maintained in vertically aligned relation by alignment plates 90. The alignment plates '90, for example, are secured to the inner shell 28A of the fin unit 24A and depend therefrom into engagement with the inner shell 28B of the subjacent fin unit 24B. A sealant material 92 seals the gap between the cap members 88A, 88B.
FIG. 9 illustrates two vertically aligned building wall fin units 24C, 24D positioned to be assembled in topto-bottom overlapping relationship. In this arrangement, the outer and inner shells 26C, 28C, for example, are coterminating at their upper ends. The outer shell 26C has a fiange portion 94 extending downwardly beyond the inner shell 28C at the bottom end of the fin unit 24C for a lapping distance indicated at 96. Additionally, the outer shell 26C is inwardly recessed as at 98 at the upper end of the fin unit 24C for a distance corresponding to the lapping distance 96. As shown in FIG. 9, the subjacent wall fin unit 24D is inwardly recessed at 98. The overall arrangement is such that the two building wall fin units 24C, 24D can be assembled in top-tobottom overlapping relation. If desired, a bead 100 of sealant material may be provided along the cap member 88C of the fin unit 24C. The bead 100 will be compressed by the cap members 88C, 88D to provide an essentially weather tight seal between the two fin units 24C, 24D.
Refering again to FIG. 5, the fin unit 24 terminates in upper end 101 which may be provided with an internal closure element 102. The periphery of the closure element 102 is engaged with the inner shell 28 and is secured thereto by suitably fasteners 104.
The present building wall fin unit can be provided in the profiles of FIGS. 2, 3 and 4 and other profiles such as illustrated in FIGS. 10-13, inclusive. The building wall fin units 106, 108, and 112 have inner and outer shells 26, 28; a lightweight foamed insulating material 32 disposed between the shells 26, 28; and bracket means 33.
