WALL CONSTRUCTION Filed Aug. 5, 1961 2 Sheets$heet 2 INVENTOR. PO) A M0715 wyydQ 3,080,022 WALL CONSTRUCTION Roy F. Mote, Stoney Creelr, Ontario, Canada, assignor to H. H. Robertson Company, Pittsburgh, Pin, a corporation of Pennsylvania Filed Aug. 3, 1961, Ser. No. 129,118 6 Claims. (Cl. 189-34) This invention relates to wall construction and more particularly to double sheathed walls.

According to the present invention, a plurality of channel shaped, metal inner pans is applied in outboard relation to the structural framework of a building skeleton (a) to serve as an inner metal sheath and also (b) to serve as spaced mounting posts for slotted vertical mullions. A plurality of bowed, normally flat outer facing sheets is provided between each pair of vertical mullions to serve as an outer sheath for the building.

The invention will be described by reference to the accompanying drawings in which:

FIGURE 1 is a cross-section plan view of the building wall of this invention taken along a corner of the building;

FIGURE 2 is an exploded perspective illustration of a pair of side-by-side inner pans and a portion of a slotted vertical mullion;

3,080,022 Patented Mar. 5, 1963 It will be observed that the spacing of successive vertical slotted mullions 13 along a building wall surface is determined by the width of the webs 15 of the inner pan sections 14.

An outer facing sheet 29 is provided in normally fiat rectangular form. The outer facing sheet 29 is snapped into position between each pair of adjacent vertical slotted mullions 18 by positioning its parallel opposed edges within the grooves 26 of adjacent vertical slotted mullions 18.

The outer facing sheets 29 preferably are formed from metallic substances such as stainless steel, aluminum, porcelainized enamel metal sheets, painted metal sheets, plastic coated metal sheets, protected metal sheets, and plastic sheets such as glass-fiber-filled polyester resin sheets. The outer facing sheets 29' are bowed between the adjacent vertical mullions 18. The outer facing sheets 29 may be additionally secured to the building structure by means of a centrally positioned fastener such as a metal screw 3%) which extends through the outer facing sheet 29 into a subgir-t 12. Alternatively the fastener could comprise FIGURE 3 is an enlargement of a portion of the wall seen in FIGURE 1;

FIGURE 4 is a fragmentary cross-section illustration similar to that of FIGURE 3 showing an alternative embodiment of the present invention including a layer of insulating material;

FIGURES 5 and 6 are fragmentary perspective illustrations of alternative constructions embodying thermal insulating material interposed between the outer and inner sheathing sheets; and

FIGURE 7 is a fragmentary cross-section View of a plastic vertical mullion which can be employed in the present invention.

Referring to FIGURE 1 there is illustrated in cross section a plan view of a corner portion of a building 10 which includes as the skeletal framework structural elements such as vertical columns 11 and horizontal subgirts 12. A vertical angle column 13 may be provided in the building skeletal structure.

Secured to the subgirts 12 in outboard relation are a plurality of inner metal pans 14, more clearly seen in FIGURES 2 and 3. Each individual pan 14 is channelshaped and includes a web 15 or central base and a pair of flange legs 16 extended at right angles to the web 15. The inner pans 14 are secured to the horizontal subgirts 12 by means of threaded fasteners 17 extended through the web 15 and through the subgirts 12. It will be ob served that the inner pans 14 are assembled in side-byside abutting relation with the flange legs 16 in lengthwise abutting contact.

A slotted vertical mullion element 18 fits over the abutting flange legs 16 and is secured thereto by means of a fastener such as a screw and bolt 19, 20 respectively which extend through the vertical mullion 18 and through drilled holes 21 in the flange legs 16.

The slotted vertical mullion 1% (FIGURE 3) includes a body portion 22, a slotted end portion 23 having parallel legs 24 and a crown portion 25. Opposed lateral grooves 26 are provided longitudinally between the crown portion and the body portion 22. Openings 27 are provided through the parallel legs 24 to receive the screw 19. The slotted vertical mullion 18 may be an extruded section of aluminum, for example. Preferably a U- shaped strip of plastic material of low heat conductivity is provided between the legs 24 of the slotted vertical mullion 18 for thermal insulation and weatherproofing between the vertical mullion 18 and the flange legs 16.

a simple pop-rivet. Preferably a pad 40 of plastic or fibrous material of low thermal conductivity is interposed between the outer facing sheet 29 and the web 15 to min: imize through-conduction of heat therebetween.

From an external vantage point, the only visual ele-. ments of the present assembled wall are the outer crowns 25 (of the vertical mullions 18) and the outer facing sheets 29. It will be observed that the outer facing sheets 29 require neither forming nor shapping, i.e., they are utilized as normally, flat, rectangular sheets.

According to the modification illustrated in FIGURE 4, the outer facing sheet 29 is spaced apart from the web 15 whereby a batt 31 of insulating material (glass fibers, mineral wool fibers, foamed plastics, and the like) may be interposed between the outer facing sheet 29 and the web 15. It will be observed that the central portion A of the outer facing sheet 29 deforms the batt 31 which resiliently resists the deformation thereby serving to secure the outer facing sheet 29 in its bowed configuration.

Alternatively, as shown in FIGURE 5, a vertical Z- shaped channel 32 may be welded to the outer surface of the web 15 by means of spot welds 33. The outboard surface of the Z-shaped metal strip 32 serves as a fasten ing surface for the outer facing sheets 29 and also serves i with the vertical mullions 18 to support batts 31 of in-- sulating material. Of course, a screw could be employed in place of the weld 33-. Fastening means such as a metal screw 34- or pop rivet can be applied through the outer facing sheet 29 into the Z-shaped metal strip 32.

Preferably a pad 41 of plastic or fibrous material of low thermal conductivity is interposed between the outer facing sheet 29 and the outboard surface of the Z-shaped metal strip 32 to minimize through-conduction of heat therebetween.

In place of the vertical Z-shaped metal strip 32 of FIG- URE 5, it is possible to use several Z-shaped metal elements, as shown in FIGURE 6 wherein a section of a Z-shaped element 35 is secured at each horizontal subgirt 12 by means of a spot weld 36 extending through the web 15. In place of the spot weld 36, of course, a screw could be employed. The outer facing sheet 29 is secured within the grooves 26 of the vertical mullions 18 as before and is fastened at its center portion by means of a screw 37 extending into the outer surface of the Z-shaped element 35. The Z-shaped elements 35 also serve to confine batts 31 of thermal insulating material. Preferably a pad 42 of plastic or fibrous material of low thermal conductivity is interposed between the outer facing sheet 29 and the outboard surface of the Z-shaped metal elements 35 to minimize through-conduction of heat therebetween.

The plastic material pads 40, 41, 42 may comprise a small section of plastic tape or a fibrous pad adhesively secured over one of its surfaces to the metal structure. Although not specifically illustrated herein, it will be apparent that the Z-sh-aped metal strip 32 also could be provided horizontally against the building skeletal framework instead of vertically as illustrated in FIGURE 4.

The split vertical mullion, as shown in FIGURE 7, may be fabricated by extrusion of plastic substances of relatively low thermal conductivity and substantial toughness. Referring to FIGURE 7, the vertical mullion 18' has a body portion 22', a slotted end portion 23' having parallel legs 24 and a crown portion 25'. Opposed la eral grooves 26' are provided longitudinally between the crown portion 25' and the body portion 22'. The vertical mullion 43' is secured to the abutting flange legs 16 by means of a screw 19 and bolt 2%. The vertical mullion 4.3 serves as a barrier to any metaLto-metal through-conduction between outer facing sheets 29 andthe pans 14 to minimize heat conduction through the wall.

Suitable plastic composition for the vertical mullions 43 include polyvinyl-chloride, epoxies, polyamides, polycarbonates' and the like.

As illustrated in the drawings, all of the inner metal pans 14 have the same width. When these inner metal pans Mare abutted and secured to the building skeleton, the flange legs '16 will be accurately spaced apart for subsequent assembly of the outer facing sheets 29. The actual distance between the longitudinal grooves 2d of the vertical mullions should be slightly less than the width of each individual facing sheet 29. This predetermined spacing will provide the desired bowed configuration of the normally flat facing sheets 29 when they are fitted into position.

Where the architectural features of the building provide panels of differing widths, then differing width-pans are provided which correspond to the architectural features of the building. The, outer facing sheets 29 also would correspond in width to the architectural features. The inner metal pans 14 of the present invention permit the assembly of the building with accurately positioned ver tical mullions even where the architectural features require differential widths.
