Patented Feb. 28, 1939 UNITED STATES- PATENT OFFICE 21 Claims.

The present; invention relates to an improved wall construction for buildings, characterized by the provision of unitary factory-made, or assembled, wall panels or sections, each providing both exterior and interior surfaces of a building wall, said wall construction being applicable to the roof as well as the exterior and interior walls.

In a building having walls constructed inaccordance with the present invention, each unitary panel or section generally corresponds in height to one story of the building and in width to the distance between adjacent uprights, or studs, of the building frame. In certain cases, two or more panels, one above the other, may be used to extend between adjacent floors of the building, thus reducing the panel size for easier handling. Furthermore, adjacent panels preferably overlie the supporting frame members of the building in abutting relation to provide smooth joints therebetween, so that an assembly of such panels may, if desired, completely enclose the frame members. In addition, the invention contemplates" the construction of each panel in such a manner as to obtain a maximum degree of heat insulation, use being made of a material having high structural strength and relatively low thermal conductivity, as well as of bright interior surfaces resistant to the transmission of heat by radiation by virtue of the high reflectivity and low emissivity of such surfaces, so that the material of a panel gives off or transmits heat very slowly. The above and other advantageous features of the invention will hereinafter more fully appear from the following description with reference to the accompanying drawings, in which:

Fig. 1 is a side elevation of a portion of a building wall made up of panels embodying the invention, as viewed from the outside of the building.

Fig. 2 is a vertical section through a corresponding portion of the building shown in Fig. 1, as viewed from the inside.

Fig. 3 is a vertical sectional view along the line 3--3 of Fig. l, on an enlarged scale.

Fig. 4 is a horizontal sectional view along the line 4-4 of Fig. 1.

Like reference characters refer to like parts in the different figures.

Referring first to Figs. 1 and 2, a portion of the foundation of a building is indicated at l,

on which is supported a sill 2 carrying floor joists 3 on which is laid the usual flooring 4. The customary upright exterior wooden or, if desired, other framing material frame members, or studs shown in Fig. 1, the panels A are applied to the frame of the building in such a manner as to constitute a continuous outside wall extending the width and height of the side of the building, while in Fig. 2, it is evident that, from the inside, the panels A constitute a continuous wall extending between the floor 4 and ceiling l of each story of the building.

Referring now to Figs. 3 and 4, each panel A is a unitary structure built up of a central plate '8 flanked on either side by vertically extending parallel plates 9 and Ill, and the inner opposed surfaces of the plates 8, 9 and III, which are preferably of metal, are bright or reflective, so that these surfaces will absorb and give off heat very slowly. The plates 8, 9 and Ill are united to each other at intervals and held in spaced relation by a series of horizontally disposed crossplates ll preferably provided with flanges Ila, whereby they may be secured to the respective plates 8, 9 and ID in any suitable manner, as by welding. The cross-plates II are desirably made of metal having a. relatively low heat conductivity, such as stainless steel or metal made from a nickel compound. The cross-plates II also provide apertures l2 extending therethrough, each aperture providing a lip or flange I20 which serves to greatly strengthen the plates I l against flexure and thereby stiffen the assembled plates 8, 9, Ill and II. The shape of each aperture is not necessarily circular, said apertures being of such size and shape and so located as to eliminate, to as great an extent as possible, and to control the convective air currents within the panel, the apertures being arranged in single rows between the plate 8 and each of the adjacent plates 9 and I 9 so that up-going and down-going air currents are constrained to flow through the same apertures.

The assembled plates 8, 9 and III, as held together by the cross-plates H, are secured together around their outside edges by sealing plates l3 and I4 extending horizontally and vertically, attachment to the plates l3 and I4 being readily obtained by flanges 9a and la provided by the plates 9 and I0, respectively. The plates II and H are preferably of a material having high structural strength, relatively low thermal conductivity and high resistance to corrosion, such as stainless steel or a nickel alloy. The necessity for reflective inner or outer surfaces for these plates is less apparent, by reason of the location of these plates in planes parallel to the direction of heat transfer through the panel. The plates l3 and H are fastened to the main plates in such a manner as effectively to seal the inside of the panel from the atmosphere, thus protecting the reflective surfaces from corrosive agents. Ducts for electrical systems or heating systems or the like may also be located in the panel in any desired location.

Each panel A, consisting as it does of an interior sealed air chamber of low heat mnductivity, further comprises outside wall surface plates [5 and it, these plates extending parallel to and being spaced from the plates 9 and i0, respectively. The plate l5 constitutes a portion of the exterior wall surface of the building, and

extends on all sides beyond the area of the central air space of the panel to overlap the sill 2, floor plate 6 and the vertical studs 5 which support the panel. The space between the plates 9 and I5 is filled by suitable sound insulating material l'l having a. low cost, such as wood fiber, hair quilting or other sheet or granular material. The plate 9 also extends below the floor level at the base of the panel to provide a continuation of the space between the plates and thus provide an apron l8 which shields and closes in the space between the floor joists 3 and 3', as shown clearly in Fig. 3.

The exterior wall surface plate [5 is secured to the sealing plates 13 and I and to the plate 9 by suitable flanges secured in any desired manner, or by direct welds, so that the plate l5 forms an integral part of the panel. Furthermore, the plate I5 extends below that portion of the plate 9 which forms the apron ID to provide an extension l9 that is turned inwardly at 20 to provide an expansion joint with an insert 2| of flexible material provided by the sill 2 or by the floor plate 6, as the case may be. The vertical edges of the exterior wall plate l5 which overlap the studs 5 are similarly provided with enlarged bulbous edges 22 which cooperate with insets 23 provided in the studs 5, the vertical seals between adjacent panels A, A being clearly indicated in Fig. 4.

The plate l6 which constitutes the interior building wall of each panel A is secured to the sealing plates l3 and H by flanges or welds, in substantially the same manner as is the exterior plate l5, and the space between the interior surface plate IS and the plate III is also filled by sound insulating material I I of the type previously described. The bottom of the plate may readily be shaped to provide the equivalent of a baseboard, as indicated at 24, which fits closely with the top flooring 4, while the top of the plate may be readily shaped to form a molding 25 fitting closely with the ceiling i, as clearly indicated in Fig. 3.

From the foregoing, it is apparent that each panel A provides a building wall section ready made, assembled and finished throughout, so that a house wall can readily be erected from such panels in conjunction with the ordinary framing provided in any building. Each panel A provides an integral sealed air space in which the transmission of heat is reduced to a minisurfaces enclosing this air space and the use of material of low heat conductivity extending across the space. Therefore, the walls of a building constructed of such panels will resist the transmission of heat in either direction, so that the building can be readily maintained at an even temperature throughout the year. The panel, as will be apparent, is applicable to the roofs of buildings as well as to interior and exterior vertical walls.

The preferred method of building a house utilizing my improved panels consists in laying the foundation I, sill 2, floor joist 3 and a floor 4 in the usual manner. A stud 5 is then erected and the first panel is put in place with its bottom plate l3 resting on the subfloor and its side plates [5 and I5 overlying the opposite sides of the stud. Another stud is next put in place between the spaced side edges of

plates

15 and 16 on the other edge of the panel, and successive panels and studs are erected in this manner to complete the wall.

In addition, provision is made for taking care of the expansion and contraction of the metal parts of the panel by the extension joints between abutting edges where they overlap the frame members of the building. In order to prevent expansion of a panel from setting up strains in the enclosing frame members of the building, expansion strips 26 extend both vertically and horizontally along the sides of each panel, these strips being preferably made of sheet metal possessing a considerable degree of inherent resiliency by reason of the cross-section of each strip, as indicated. Said strips 26 also prevent the passage of air, as will be apparent, by maintaining engagement at all 'times between the frame members and the edge of the panel.

While I have in this application specifically described one embodiment which my invention may assume in practice, it will be understood that the same is shown for purposes of illustration and that the invention may be modified and embodied in various other forms without departing from its spirit or the scope of the appended claims.
