B. E. CURRAN Sept. 26, 1967 EXTERIOR SIDING AND INNER SHEATHING STRUCTURE THEREFOR Filed March 24, 1965 swm y n? V T N T /D W/A J m 7 55 United States Patent 3,343,325 EXTERIOR SIDING AND INNER SHEATHING STRUCTURE THEREFOR Bernard E. Curran, Sewickley, Pa., assignor to H. H-

Robertson Company, Pittsburgh, Pa., a corporation of Pennsylvania Filed Mar. 24, 1965, Ser. No. 442,345 1 Claim. (Cl. 52478) The present invention concerns building outer wall structures of the double-sheathed variety.

The present double-sheathed Wall for a building com bines versatility of construction with ease of fabrication, simplicity and remarkable structural strength.

The present wall construction utilizes an inner sheathing formed from overlapped rectangular sheathing sections which are secured to a building framework in side-byside relation. The rectangular sheathing sections have lateral marginal flanges, one of which overlaps a marginal lateral flange of the next adjacent one of the sheathing sections, and the other of which in turn is itself overlapped by a marginal lateral flange of the other adjacent sheathing section. The two overlapped marginal flanges serve as vertical mullions for receiving a subsequently applied outer sheathing of horizontal strips of tongue-and-groove, weather-resistant sheathing. The tongue-and-groove weather-resistant sheathing is secured to the overlapped terminal marginal flanges by means of screws which extend through the outer sheathing and through both of the overlapped and overlapping flanges of the inner sheathing sections.

Tongue-and-groove sheathing of the type with which this invention is concerned is available commercially. Typical sheathing strips are described in US. Patents 3,158,960, 2,682,236 and 3,001,332 for example.

It is a further feature of this invention that suitable thermal insulation material may be applied between the outer sheathing and the inner sheathing according to well-known practices in the building art.

The present invention, its objects and advantages, will become apparent from the following detailed description with reference to the accompanying drawings in which:

FIGURE 1 is a fragmentary view of a building outer wall during construction in accordance with the present invention;

FIGURE 2 is a cross-section view taken along the lines 22 of FIGURE 1;

FIGURE 3 is a cross-section view taken along the lines 3-3 of FIGURE 1; and

FIGURES 4, 5 and 6 are cross-section views, similar to FIGURE 3, showing alternative embodiments of the horizontal sheathing element which may be utilized in the present construction.

Referring to FIGURE 1, there is illustrated a fragmentary view of a building under construction according to this invention wherein a plurality of generally horizontal subgirts 11, 12 are secured in outboard relation to the columns of the building (not shown). Spanning across and secured to the subgirts 11, 12 are a plurality of essentially rectangular inner sheathing sections 13, each being secured to the subgirts 11, 12 by means of fasteners 14. If desired, the inner sheathing sections 13 may be spotwelded to the subgirts 11, 12.

The rectangular inner sheathing sections 13 comprise an essentially rectangular central flat surface 15 having lateral outwardly disposed flanges 1-6, 17. Each of the flanges 16, 17 has a terminal marginal strip 18, 19 both of which extend in the same direction and are generally parallel with the flat surface 15. The terminal marginal strip 18 extends from the flange 17 and overlies the flat surface 15. The terminal marginal strip- 19 extend from the flange 16 and is dis-posed away from the flat surface 15. When two of the present sheathing sections 13 are assembled in side-by-side relation, the flange 16 of one is in abutting relation with the flange 17 of the other; the terminal marginal strip 19 of one is in overlying engagement with the terminal marginal strip 18 of the other. The outboard surface of the terminal marginal strip 19 serves as a mounting surface for the horizontal sheet like sheathing elements of the present wall. The sheet-like sheathing elements 20, as shown in FIGURE 3, have a tongue element 21 at one end and a groove element 22 at the other end.

Means are provided adjacent to the tongue element 22, such as a fastening lip 23, for receiving a suitable screw 24 which extends through the fastening lip 23 and through the terminal marginal strips 18, 19 as seen in FIGURE 3. The screw 24 is disposed in such manner as it will be hidden from external view in the final wall assembly.

The external horizontal sheathing elements 20' are assembled one-by-one from top-to-bottom when the strips are of the type shown in FIGURE 3 are employed.

Alternatively, the horizontal sheathing strips 20A, shown in FIGURE 4, may be employed where bottom-totop assembly of the external sheathing is desirable. As shown in FIGURE 4, the horizontal sheathing strips 20A have a fastening lip 25 adjacent to a groove element 26 and have a re-entrant tongue element 27. Sheathing elements of the general type shown in FIGURE 4 are described in US. Patents 3,001,332 and 2,766,861, for example.

A further alternative embodiment of the bottom-to-top assembly variety of horizontal sheathing elements is illustrated in FIGURES 5 and 6. The individual sheathing elements of FIGURE 5, 20B, have a fastening lip 28 and groove element 29 at one end and a re-entrant tongue element 30 at the other end. A single outwardly presented, hook-shaped flange 31 at the top of the sheathing strip 20B provides both the fastening lip 28 and the groove element 29. To assemble the wall of FIGURE 5, the lowermost horizontal strip 20B is secured by means of the fastener 32. Thereafter the next upper horizontal sheathing strip 20B is positioned in place by inserting the tongue element 31 into the groove element 28 of the lowermost strip. Thereupon the next upper horizontal strip 20B of FIGURE 5 is secured by extending the fastener 33 through the fastening lip 28. A still further embodiment of the bottom-to-top horizontal sheathing 20C is shown in FIGURE 6 which includes an outwardly presented terminal flange 34 at the end of the outwardly presented, hook-shaped flange 31. This outward flange 34, in abutment with the bottom horizontally disposed flange 35 of the sheathing element 20C serves to rigidity and strengthen the wall assembly.

If desired, batts of thermal insulating materials such as fibrous mineral wool, fibrous glass, foam resinous substances such as foamed polystyrene or foamed polyurethane may be secured to the inner sheathing sections 13 beneath the outer horizontal sheathing elements 20. Such insulation batts are identified by the numeral 36.

The present wall construction avoids the need for inter vening subgirts between the inner shetahing sections 13 and the external horizontal sheathing elements 20.

A preferred form of the inner sheathing sections 13 is described in co-pending U.S. patent application S.N. 425,- 517, filed Jan. 14, 1965, and assigned to the assignee of the present invention.

The inner sheathing sections 13 preferably are fabricated from steel such as galvanized steel sheets having a thickness from 12 through 22 gauge.

The outer sheathing elements 20 may be fabricated from a variety of materials such as metals, plastics and the like. Steel sheeting or aluminum sheeting is satisfactory. The external sheathing should be provided with a weatherresistant exterior coating such as porcelainized enamel,

weather-resistant paints or enamels, adhesively secured plastic films, resinous coatings and the like. A preferred material for use in the external sheathing elements 20 is protected metal fabricated from zinc-coated steel sheets having an asphalt-impregnated asbestos covering secured to the metal sheet which is in turn covered a suitable weather-resistant resinous substance. Such preferred protected metals are described, for example, in US. Patents 1,862,332 and 2,073,334.
