VENTILATING WALL CONSTRUCTION Filed Nov. 8, 1961 Qm I8 v INVENTOR. JOSEPH CHARNIGA JR.
ATTO NE Y United States Patent 3,124,847 VENTILATING WALL CONSTRUCTION Joseph Charuiga, In, Box 296, Poland 14, Ohio Filed Nov. 8, 1961, Ser. No. 151,041 1 Claim. (Cl. 20-4) This invention relates to building construction and more particularly to frame building constructions such as used in dwelling houses and the like.
The principal object of the invention is the provision of an improved ventilated wall construction which prevents the build-up of moisture in the wall and thereby eliminates moisture damage to the wall.
A further object of the invention is the provision of a frame building construction for exterior walls providing means establishing intercommunication of the areas between the studding in the walls.
A still further object of the invention is the provision of an improved frame construction for buildings such as dwelling houses and the exterior walls thereof in particular and whereby air circulation is effected within said walls by providing for the intercommunication of the several air spaces therein and establishing communication between the same and a warm air heating system in the dwelling.
The improved building construction disclosed herein relates to frame construction as commonly employed in dwelling houses and wherein the exterior walls are formed of spaced vertical studding with sheathing and siding ap plied to the exterior thereof and lath and plaster or dry wall material to the interior thereof. As heretofore formed such walls provided a number of separate dead air spaces between the several studding and formed effective moisture traps through the use of waterproofed coatings on the sheathing so that moisture from the interior of the dwelling passing through the lath and plaster or dry wall material condensed in the dead air spaces on the inner side of the sheathing with resultant water damage to the several parts of the wall. This water damage frequently took the form of blistering and peeling paint on the exterior of the siding on the wall and dry rot within the wall and frequently caused peeling and loosening of the decorative material applied to the lath and plaster or dry wall forming the interior surface of the wall.
The present invention provides for the establishment of intercommunicating air circulating passageways between the various areas defined by the studding and the establishment of communication between at least one of such areas in the intercommunicating system with the cold air returns of the Warm air heating system in the dwelling so that air in the wall is gently circulated therethrough and drawn into the heating system.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being the intention to cover all changes and modifications of the example of the invention herein chosen for purposes of the disclosure, which do not constitute departures from the spirit and scope of the invention.
The invention is illustrated in the accompanying drawing, wherein:
FIGURE 1 is a perspective view of a section of an exterior wall and floor of a building construction illus trating the improved air circulating formation.
FIGURE 2 is a plan view of a section of sheathing used in the wall shown in FIGURE 1.
FIGURE 3 is an end view thereof.
FIGURE 4 is an end view of a section of wooden sheathing used in the wall shown in FIGURE 2.
3,124,847v Patented Mar. 17., 1964 "ice By referring to the drawings and FIGURE 1 in particular, it will be seen that a foundation block. 10 which may be the top one of a wall or similar block is illustrated as supporting a plate 11 upon which a sill 12 is positioned to form an abutment for the ends of a plurality of joists 13 which rest upon the plate 11 as known in the art. A sub-floor 14 and a finished floor 15 are installed on the upper side of the joists 13 and extend inwardly away from the sill 12. A plurality of studding 16 are positioned vertically in horizontally spaced relation to one another on the flooring 14 or upon a secondary 2 x 4 plate laid thereon as will be understood by those skilled in the art. Sections of sheathing 17 are aifixed to the exterior of studding 16 and the sheathing 17 comprises rigid sheets of suitable material having a plurality of horizontally disposed vertically spaced ribs 18, 18 on their innermost surfaces as best seen in FIGURES 2, 3 and 4 of the drawings. By referring thereto, it will be seen that the section of sheathing material which may be formed in the manner of Celotex or similar cane fibre insulating sheet, has a flat outer surface 17A and a ribbed inner surface 17B. The ribbed inner surface carries the plurality of vertically spaced horizontally extending projecting ribs 18, 18 which may be cross sectionally square or rounded and which provide effective spacing members between the outer sides of the studding 16 and the inner surface 17B of the sheathing. The sheathing 17 may be and preferably is provided with waterproof coating material on one or both sides as known in the art, and which waterproof coating material may also cover said ribs 18.
By referring again to FIGURE 1 of the drawings, it will be seen that horizontal siding 19 is positioned in superimposed overlapping relation on the exterior of the sheathing 17 of the wall and it will be understood that it is nailed thereto and with the nails extending through the sheathing 17, the air space between the siding and the studding 16 and into the studding.
The inner side of the wall comprises a layer of lath and plaster 20 or dry wall board as known in the art which is afiixed to the studding 16. It will thus be seen that the air spaces formed between the plurality of horizontally spaced vertical positioned studding 16 communicate with one another through the spaces formed between the vertically spaced horizontal ribs 18 on the siding 17.
By referring to FIGURE 1 of the drawings it will be seen that a cold air return duct 21 is shown extending along one of the joists 13 from a warm air heating system (not shown) and leading upwardly at its outer end into a cold air boot 22 which communicates with the interior of the areas defined by the wall as heretofore described by way of a grill 23. The cold air boot 22 has a plurality of apertures 24 in its uppermost portion so that the air in the areas between the studding 16 may be drawn into the cold air boot 22 and the duct 21 by the operation of the furnace in the heating system and as indicated by the arrows in FIGURE 1 of the drawings. It will also be seen that cold air enters the boot 22 and the duct 21 by way of the grill 23 from the room enclosed by the wall and that the majority of the air entering the cold air duct 21 enters through the grill 23 which has a relatively greater number of apertures therein than the number of apertures 24 which communicate with the interior areas of the wall construction.
It will occur to those skilled in the art that a satisfactory ventilating action in the wall construction herein disclosed may be achieved in locations where there is no warm air heating system by providing suitable openings in the secondary plate and floor which the studding rest upon and in the cap plate at the top of the wall so that air may flow downwardly or upwardly therethrough,
thereby utilizing the disclosed construction to achieve the several objects of the invention.
It will thus be seen that a ventilated wall construction has been disclosed which meets the several objects of the invention, and having thus described my invention, what I claim is:
The combination in a frame wall construction of studding forming a framework and defining a plurality of spaced chambers, an interior wall material on one side of said studding and exterior Wall material comprising sheathing boards formed of cane fibre or the like on the other side of said studding, said exterior wall material having a plurality of integral spaced ribs positioned to space the major portion of said exterior wall material with respect to said studding and thereby establish communication between said spaced chambers.
